Revision	Date	Author	Comments
1.2	24-Feb-2002	uch	branches: 1.2.12; clean up Makefiles
1.1	13-Sep-1999	itojun	branches: 1.1.16; Merge in NetBSD/sh3 from cvs.kame.net repository. Tree structure: - sys/arch/sh3: sh3 generic code As commented, in-chip device drivers are put into sys/arch/sh3/dev. - sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW) - sys/arch/mmeye: Brains mmEye, www.brains.co.jp MI source code includes couple of #ifdef for sh3-coff support. (sh3 uses coff or elf) Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3, to compile the tree (due to last minute tree structure change).
1.1.16.1	16-Mar-2002	jdolecek	Catch up with -current.
1.2.12.2	24-Feb-2002	uch	clean up Makefiles
1.2.12.1	24-Feb-2002	uch	file Makefile was added on branch nathanw_sa on 2002-02-24 20:10:54 +0000
1.1	24-Feb-2002	uch	branches: 1.1.2; 1.1.8; 1.1.16; Move common exception vector and scheduler code to sh3/sh3/exception_vector.S and sh3/sh3/locore_subr.S. exception vectors are installed by sh_cpu_init(). machine/locore.S contains kernel entry, interrupt handler, and some MD code.
1.1.16.2	24-Feb-2002	uch	Move common exception vector and scheduler code to sh3/sh3/exception_vector.S and sh3/sh3/locore_subr.S. exception vectors are installed by sh_cpu_init(). machine/locore.S contains kernel entry, interrupt handler, and some MD code.
1.1.16.1	24-Feb-2002	uch	file Makefile.inc was added on branch nathanw_sa on 2002-02-24 18:19:44 +0000
1.1.8.2	16-Mar-2002	jdolecek	Catch up with -current.
1.1.8.1	24-Feb-2002	jdolecek	file Makefile.inc was added on branch kqueue on 2002-03-16 15:59:34 +0000
1.1.2.1	28-Feb-2002	nathanw	Catch up to -current.
1.29	22-Sep-2018	rin	- Determine KERN_AS automatically depending on whether OPT_MODULAR is set or not, in the same way as libcompat. - Specify OPT_MODULAR in the port Makefile instead of KERN_AS. Now, KERN_AS=library is used for kernels without module(7) for all ports. OK christos
1.28	10-Mar-2013	christos	branches: 1.28.36; 1.28.38; Explicitly set KERN_AS (this could be done in /usr/src/sys/conf/Makefile.*) so that modules work, on config files that did not set it explicitly. All the files now use the standard logic, except the ones that set KERN_AS=obj and Makefile.usermode which sets KERN_AS=library.
1.27	21-Jan-2011	joerg	branches: 1.27.4; 1.27.14; Switch remaining platforms to modern CPP for assembler.
1.26	06-May-2008	uwe	branches: 1.26.22; 1.26.28; 1.26.30; Default COPTS to "-Os -freorder-blocks" which is ~= -O2 but without -falign-* that is too zealous for low-memory sh3 machines. I've been using this for my hpcsh and landisk kernels for a very long time. (besides, it's not 2001 anymore and pkgsrc/cross/sh is long since gone).
1.25	01-Mar-2008	joerg	branches: 1.25.2; 1.25.4; Missing assym.h dependencies.
1.24	28-Mar-2007	uwe	branches: 1.24.14; 1.24.30; 1.24.34; G/c ancient workaround that has been commented out for ages.
1.23	02-Sep-2006	uwe	branches: 1.23.8; 1.23.12; 1.23.14; 1.23.16; There's no reason to use -Wno-parentheses.
1.22	17-Mar-2006	uebayasi	Stop using linker scripts on all sh3 ports. The only information to be compensated is text section start address. The default value is set arch-wise as DEFTEXTADDR. Each kernel config can override the default value by setting TEXTADDR. Tested on COMPUTEXEVB (evbsh3). Reviewed By: uwe
1.21	11-Dec-2005	christos	branches: 1.21.4; 1.21.6; 1.21.8; 1.21.10; 1.21.12; merge ktrace-lwp.
1.20	31-May-2005	christos	branches: 1.20.2; s/GENASSYM/GENASSYM_CONF/ so we can use "GENASSYM" as the program name.
1.19	04-Jun-2004	thorpej	Add the %MAKEOPTIONSAPPEND token at the end of the file, after the common Makefile.kern.inc has been included.
1.18	17-Mar-2002	uch	branches: 1.18.8; 1.18.14; 1.18.18; cosmetic changes, fix comments.
1.17	24-Feb-2002	uch	Move common exception vector and scheduler code to sh3/sh3/exception_vector.S and sh3/sh3/locore_subr.S. exception vectors are installed by sh_cpu_init(). machine/locore.S contains kernel entry, interrupt handler, and some MD code.
1.16	09-Dec-2001	atatat	Roll the rest of the ports over to the new MI kernel build machinery. Any problems reported by testers have been fixed, and massive cross-compiling of kernels has shown that any problems that remain with actually building kernels are not related to this.
1.15	20-Nov-2001	lukem	cleanup: options SPACE TAB makeoptions TAB psuedo-device TAB remove trailing whitespace replace multiple spaces -> tabs options "FOO" -> options FOO options "FOO=bar" -> options FOO=bar options "FOO=\"bar\"" -> options FOO="\"bar\""
1.14	26-Oct-2001	jmc	Change defaults for kernel compiles. Default all to USETOOLS?=no and have the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES This way the default for kernel compiles is still to use the installed toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by simply adding USETOOLS=yes to the command line as usual. Adjust each ports template to set the default no setting and also pull in bsd.own.mk if they weren't already to ensure they'll build correctly with the new toolchain setup.
1.13	23-Oct-2001	thorpej	branches: 1.13.2; Use MACHINE, not TARGET_MACHINE.
1.12	29-May-2001	mrg	branches: 1.12.2; define _KERNEL_OPT as well as _KERNEL. we will use this in the future to get kernel "opt_foo.h" headers, rather than _KERNEL && !_LKM.
1.11	24-Mar-2001	matt	Use ${THISSH3} instead of ../.. ; not everyone builds in ../compile/FOO
1.10	22-Jan-2001	tsubai	branches: 1.10.2; -Dsh3 --> -D${TARGET_MACHINE}.
1.9	04-Jan-2001	itojun	use -O1 for now, -O2 dies
1.8	03-Jan-2001	itojun	share sys/arch/sh3/conf/Makefile.sh3 across sh3-based architectures. cleanup param.h a bit.
1.7	17-Dec-2000	jdolecek	delete obsolete comment
1.6	09-May-2000	hubertf	Add "install" target, so "make install" after building the kernel does something useful. The target can be redefined by putting a install-kernel-${MACHINE_NAME} target that fits your needs into /etc/mk.conf.
1.5	09-May-2000	thorpej	HAVE_GCC28 -> HAVE_EGCS, and make it match gcc 2.9 as well. Also, make the use of -Wno-uninitialized explicit, don't rely on a compiler hack to do it for us.
1.4	01-Feb-2000	tsutsui	Revert STRIPPROG -> STRIP
1.3	24-Jan-2000	tron	Add "dependall" target for comfort.
1.2	19-Jan-2000	tsutsui	STRIP -> STRIPPROG
1.1	13-Sep-1999	itojun	branches: 1.1.2; Merge in NetBSD/sh3 from cvs.kame.net repository.

Pull the bus_space(9) routines into a new module, sh3/sh3/sh3_bus_space.c, that is built only on !landisk. Fixes the mmeye and landisk builds. Should fix other sh3 ports.
1.44	12-Jun-2011	rmind	Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.
1.43	22-Nov-2008	uwe	branches: 1.43.8; 1.43.14; Sort
1.42	22-Nov-2008	uwe	Move COMPAT_16 signal stuff to the new compat_16_machdep.c file, so that it can be built as part of a module.
1.41	19-Nov-2008	ad	Make the emulations, exec formats, coredump, NFS, and the NFS server into modules. By and large this commit: - shuffles header files and ifdefs - splits code out where necessary to be modular - adds module glue for each of the components - adds/replaces hooks for things that can be installed at runtime
1.40	15-Mar-2008	uwe	branches: 1.40.4; 1.40.10; 1.40.12; defflag cache related options.
1.39	02-Feb-2008	uwe	branches: 1.39.2; 1.39.6; Add cpu_in_cksum.S
1.38	01-Feb-2008	tsutsui	Catch up with "Refactor in_cksum/in4_cksum/in6_cksum implementations".
1.37	25-Jan-2008	joerg	Refactor in_cksum/in4_cksum/in6_cksum implementations: - All three functions are included in the kernel by default. They call a backend function cpu_in_cksum after possibly computing the checksum of the pseudo header. - cpu_in_cksum is the core to implement the one-complement sum. The default implementation is moderate fast on most platforms and provides a 32bit accumulator with 16bit addends for L32 platforms and a 64bit accumulator with 32bit addends for L64 platforms. It handles edge cases like very large mbuf chains (could happen with native IPv6 in the future) and provides a good base for new native implementations. - Modify i386 and amd64 assembly to use the new interface. This disables the MD implementations on !x86 until the conversion is done. For Alpha, the portable version is faster.
1.36	06-Jan-2008	ad	Add MODULAR option. Include kernel linker stuff if MODULAR.
1.35	17-Oct-2007	garbled	branches: 1.35.2; 1.35.8; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

(sh3 uses coff or elf) Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3, to compile the tree (due to last minute tree structure change).

1.14	24-Apr-2021	thorpej	branches: 1.14.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.13.74.6	05-Apr-2021	thorpej	Treat config_probe() as if it were a boolean function; don't compare return value > 0... except for the odd balls, which are now really easy to spot.
1.13.74.5	05-Apr-2021	thorpej	config_match() -> config_probe() for the straight-forward indirect config cases. There are still a few odd balls using config_match() which should be sorted out later.
1.13.74.4	04-Apr-2021	thorpej	CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
1.13.74.3	03-Apr-2021	thorpej	Give config_attach() the tagged variadic argument treatment and mechanically convert all call sites.
1.13.74.2	21-Mar-2021	thorpej	CFARG_IATTR usage audit: If a device carries only one interface attribute, there is no need to specify it when calling config_search(); that specification is meant only to disambiguate which interface attribute (which is a proxy for "what kind of attach args are being used") is having children attached. cfparent_match() will take care of ensuring that any potential children can attach to one of the parent's iterface attributes, and if the parent only carries one, no disambiguation is necessary.
1.13.74.1	20-Mar-2021	thorpej	The proliferation if config_search_() and config_found_() combinations is a little absurd, so begin to tidy this up: - Introduce a new cfarg_t enumerated type, that defines the types of tag-value variadic arguments that can be passed to the various config_() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS, for now, plus a CFARG_EOL sentinel). - Collapse config_search_() into config_search() that takes these variadic arguments. - Convert all call sites of config_search_*() to the new signature. Noticed several incorrect usages along the way, which will be audited in a future commit.
1.14.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().

1.13	13-Oct-2025	thorpej	Use "start-year" than "sh3_rtc_baseyear" as the RTC base year property name, matching the dsrtc driver and the Devicetree binding.
1.12	07-Sep-2025	thorpej	Change todr_chip_handle::cookie -> todr_chip_handle::todr_dev, and make it a device_t. Upcoming functional changes will require the device_t associated with a TODR device. Change todr_chip_handle::bus_cookie -> todr_chip_handle::todr_devaux. Nothing was using the old field, but I decided to keep it around just in cause something needs it in the future.

For dates in the year 2000 or later, use arithmetic instead (since the repeating periods are well aligned). Should fix PR 49144. -- Avoid overflowing the "year" value by making the field uint64_t. Adapt arguments and local variables accordingly. This now fixes PR 49144 for real. -- Adapt formats for debug printfs to clock_subr type changes.

Tested with release builds on amd64 and evbarm and live testing on amd64.

This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted.

1.28	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

1.13	02-May-2001	scw	Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point in each tty driver to indirect through it. This allows tty line-disciplines to handle poll(2) system calls.
1.12	14-Jan-2001	thorpej	branches: 1.12.2; Rename __GENERIC_SOFT_INTERRUPTS to __HAVE_GENERIC_SOFT_INTERRUPTS, and place the definition in <machine/types.h>. This can now be used as a flag to indicate whether or not <machine/intr.h> can be included to get the generic soft interrupt API.

1.7	23-Mar-2000	thorpej	New callout mechanism with two major improvements over the old timeout()/untimeout() API: - Clients supply callout handle storage, thus eliminating problems of resource allocation. - Insertion and removal of callouts is constant time, important as this facility is used quite a lot in the kernel. The old timeout()/untimeout() API has been removed from the kernel.

1.1	13-Sep-1999	itojun	Merge in NetBSD/sh3 from cvs.kame.net repository. Tree structure: - sys/arch/sh3: sh3 generic code As commented, in-chip device drivers are put into sys/arch/sh3/dev. - sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW) - sys/arch/mmeye: Brains mmEye, www.brains.co.jp MI source code includes couple of #ifdef for sh3-coff support. (sh3 uses coff or elf) Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3, to compile the tree (due to last minute tree structure change).

1.70	16-Sep-2023	andvar	sh3/scif(4): redefine DPRINTF again, not all SH ports has machine/debug.h. Those are defined for hpc only. unbreaks build for evbsh some kernel configs and SFIC_DEBUG still builds.
1.69	15-Sep-2023	andvar	sh3/scif(4): replace undefined scifstatus with DPRINTF. fixes the build with SCIF_DEBUG enabled.
1.68	21-Nov-2020	thorpej	malloc(9) -> kmem(9)
1.67	10-Nov-2019	chs	branches: 1.67.8; in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT and remove code to handle failures that can no longer happen.
1.66	06-Dec-2015	tsutsui	branches: 1.66.18; Make options SCIFCONSOLE patchable via a variable using gdb(1) etc. Tested on dreamcast.
1.65	15-Nov-2014	christos	branches: 1.65.2; centralize the call unit / dialout macros
1.64	25-Jul-2014	dholland	Add d_discard to all struct cdevsw instances I could find. All have been set to "nodiscard"; some should get a real implementation.
1.63	16-Mar-2014	dholland	branches: 1.63.2; Change (mostly mechanically) every cdevsw/bdevsw I can find to use designated initializers. I have not built every extant kernel so I have probably broken at least one build; however I've also found and fixed some wrong cdevsw/bdevsw entries so even if so I think we come out ahead.
1.62	09-Nov-2013	christos	fixed unused variable warning
1.61	02-Feb-2012	tls	branches: 1.61.6; 1.61.10; Entropy-pool implementation move and cleanup. 1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev. 2) Remove use of NRND as test for presence of entropy-pool code throughout source tree. 3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit. 4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources. 5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each. ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.
1.60	24-Apr-2011	rmind	branches: 1.60.4; 1.60.8; Rename ttymalloc() to tty_alloc(), and ttyfree() to tty_free() for consistency. Remove some unnecessary malloc.h inclusions as well.

1.54	19-Nov-2007	ad	- Factor out too many copies of the same bit of tty code. - Fix another tty signalling/wakeup problem.
1.53	06-Nov-2007	uwe	Misc cleanup: use device_* and aprint_*, group declarations, g/c some dead code, etc.
1.52	17-Oct-2007	garbled	branches: 1.52.2; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.51	09-Jul-2007	ad	branches: 1.51.8; 1.51.10; 1.51.14; Merge some of the less invasive changes from the vmlocking branch: - kthread, callout, devsw API changes - select()/poll() improvements - miscellaneous MT safety improvements
1.50	04-Mar-2007	christos	branches: 1.50.2; 1.50.4; 1.50.10; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

1.38	13-Dec-2004	chs	for drivers that support only one instance, use a global variable to ensure that only one instance is configured rather than requiring that its unit number be zero.
1.37	19-Oct-2004	uwe	First step towards bus_space - wrap register accesses into macros. Same object code is generated.
1.36	19-Oct-2004	uwe	KNF cosmetic. Same object code is generated. Use continue for explicit empty loop body. Use for (;;) instead of while (1). Fix an indentation glitch.
1.35	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.

1.30	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.29	27-Sep-2002	thorpej	Rather than referencing the cfdriver directly in the cfdata entries, instead use a string naming the driver. The cfdriver is then looked up in a list which is built at run-time.
1.28	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.

(sh3 uses coff or elf) Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3, to compile the tree (due to last minute tree structure change).

1.15	24-Apr-2021	thorpej	branches: 1.15.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.14.78.2	21-Mar-2021	thorpej	CFARG_IATTR usage audit: If a device carries only one interface attribute, there is no need to specify it when calling config_search(); that specification is meant only to disambiguate which interface attribute (which is a proxy for "what kind of attach args are being used") is having children attached. cfparent_match() will take care of ensuring that any potential children can attach to one of the parent's iterface attributes, and if the parent only carries one, no disambiguation is necessary.
1.14.78.1	20-Mar-2021	thorpej	The proliferation if config_search_() and config_found_() combinations is a little absurd, so begin to tidy this up: - Introduce a new cfarg_t enumerated type, that defines the types of tag-value variadic arguments that can be passed to the various config_() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS, for now, plus a CFARG_EOL sentinel). - Collapse config_search_() into config_search() that takes these variadic arguments. - Convert all call sites of config_search_*() to the new signature. Noticed several incorrect usages along the way, which will be audited in a future commit.

1.20	07-Jul-2020	thorpej	branches: 1.20.4; Overhaul the interface to pci_configure_bus(): - Don't expose how PCI bus configuration resource management is implemented. Provide a new resource provider API: ==> pciconf_resource_init() -- Initialize a PCI configuration resources container. ==> pciconf_resource_add() -- Add a PCI configuration resource to the container (I/O, MEM, or prefetchable MEM). Multiple resources of each type may be added. ==> pciconf_resource_fini() -- Tear down the PCI configurtation resources container once the bus has been configured. This is much easier to use than the previous method of providing an extent map for each kind of resource, and works better for e.g. ACPI platforms that provide potentially multiple PCI resources in tables provided by firmware. - Re-implement PCI configuration resource management using vmem arenas, rather than extent maps.

Currently the following extended capabilities are decoded: - Advanced Error Reporting - Virtual Channel - Device Serial Number - Power Budgeting - Root Complex Link Declaration - Root Complex Event Collector Association - Access Control Services - Alternative Routing-ID Interpretation - Address Translation Services - Single Root IO Virtualization - Page Request - TPH Requester - Latency Tolerance Reporting - Secondary PCI Express - Process Address Space ID - LN Requester - L1 PM Substates The following extended capabilities are not decoded yet: - Root Complex Internal Link Control - Multi-Function Virtual Channel - RCRB Header - Vendor Unique - Configuration Access Correction - Multiple Root IO Virtualization - Multicast - Resizable BAR - Dynamic Power Allocation - Protocol Multiplexing - Downstream Port Containment - Precision Time Management - M-PCIe - Function Reading Status Queueing - Readiness Time Reporting - Designated Vendor-Specific

Correct that. Rename PCI_FLAGS_IO_ENABLED to PCI_FLAGS_IO_OKAY and PCI_FLAGS_MEM_ENABLED to PCI_FLAGS_MEM_OKAY, thus making their names consistent with the other PCI flags and poisoning 3rd-party driver sources that use the flags in the old bad way.

1.7	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

These files are also required to supply inline functions __cpu_simple_lock(), __cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be supported on that platform (i.e. if MULTIPROCESSOR is defined in the _KERNEL case). Change these functions to take an int * (&alp->lock_data) rather than the struct simplelock * itself. These changes make it possible for userland to use the locking primitives by including <machine/lock.h>.

1.17	07-May-2019	kamil	Switch all users (except ia64) of custom machine/ansi.h to common_ansi.h Deduplicate the code among ports and poll definitions of types directly from a compiler. This fixes miscompilation of certain programs that instruct compilers to generate code for different types. This bug has been detected with -fshort-wchar in EFI firmware. Proposed and discussed on a mailing list (twice). Itanium uses custom !ELF fallback switch, temporarily leave it as it is.

Move machine/stdarg.h logic into MI sys/stdarg.h and expect compiler to provide proper builtins, defaulting to the GCC interface. lint still has a special fallback. Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.
1.14	27-Mar-2010	tnozaki	1. {wctype,wctrans,mbstate}_t: switch MD to MI like other libc implementation (such as BSD and glibc2). 2. don't typedef void wc{type,trans}_t, suggested by soda@-san. it may pass through compiler type check, it's harmful. so i introduce dummy struct __tag_wc{type,trans}_t(iconv_t already does). no ABI change was made.

This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.9	15-May-2006	uwe	branches: 1.9.8; 1.9.10; Change _BSD_VA_LIST_ from "void " to "__builtin_va_list" for newer gcc versions and "char " otherwise. This is what most other arches use, modulo different __GNUC_PREREQ__. This is in preparation for replacing stdarg.h and varargs.h with versions based on __builtin_* instead of handwritten code that gcc 3.3.6 and up refuse to compile b/c of lhs casts.

Note that some bus_space(9) routines' implementation will move to .c files from inline subroutines or macros in .h files. I've only made the split for machine architectures where there is PCI. All of the non-PCI-having architectures will require a similar split. These #include files are not referenced by any (committed) Makefiles or header files, yet. Changes to Makefiles, to <sys/bus.h>, and to some more machine-dependent files will dribble in before I throw the switch.

Pull the bus_space(9) routines into a new module, sh3/sh3/sh3_bus_space.c, that is built only on !landisk. Fixes the mmeye and landisk builds. Should fix other sh3 ports.
1.3	25-Jul-2011	dyoung	Move the sh_memio_*() declarations back to sh3/include/bus_funcs.h. Should fix the mmeye build.

1.61	23-Feb-2022	andvar	fix various typos in comments, mainly immediatly/immediately/, as well shared and recently fixed typos in OpenBSD code by Jonathan Grey.
1.60	03-Aug-2020	uwe	SH3_P2SEG_FUNC(f) - get a P2 address of a function. Just SH3_P1SEG_TO_P2SEG + cast, but we now define SH3_P1SEG_TO_P2SEG and SH3_P2SEG_TO_P1SEG to use arithmetic, not bitwise ops. That gives the same result for the correct P1/P2 input values, but addition can be done at link time with addends. Thus SH3_P2SEG_FUNC compiles to a constant P2 address.
1.59	01-Dec-2019	ad	Fix false sharing problems with cpu_info. Identified with tprof(8). This was a very nice win in my tests on a 48 CPU box. - Reorganise cpu_data slightly according to usage. - Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc). - On x86, put some items in their own cache lines according to usage, like the IPI bitmask and ci_want_resched.
1.58	23-Nov-2019	ad	cpu_need_resched(): - Remove all code that should be MI, leaving the bare minimum under arch/. - Make the required actions very explicit. - Pass in LWP pointer for convenience. - When a trap is required on another CPU, have the IPI set it locally. - Expunge cpu_did_resched().
1.57	22-Aug-2018	msaitoh	- Cleanup for dynamic sysctl: - Remove unused _NAMES macros for sysctl. - Remove unused _MAXID for sysctls. - Move CTL_MACHDEP sysctl definitions for m68k into m68k/include/cpu.h and use them on all m68k machines.
1.56	19-Oct-2013	christos	branches: 1.56.28; 1.56.30; make cpu_need_resched() macros consistent; __USE flags
1.55	22-Dec-2010	nisimura	branches: 1.55.8; 1.55.18; 1.55.22; PROC_PC() should have been changed to LWP_PC().
1.54	21-Oct-2009	rmind	branches: 1.54.4; Remove uarea swap-out functionality: - Addresses the issue described in PR/38828. - Some simplification in threading and sleepq subsystems. - Eliminates pmap_collect() and, as a side note, allows pmap optimisations. - Eliminates XS_CTL_DATA_ONSTACK in scsipi code. - Avoids few scans on LWP list and thus potentially long holds of proc_lock. - Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k. - Removes __SWAP_BROKEN cases. Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on acorn26 (thanks to <bjh21>). Discussed on <tech-kern>, reviewed by <ad>.
1.53	22-Mar-2008	uwe	branches: 1.53.4; Revert interrupt stack changes. There are some issues and, at least in the current form, they complicate implementation of fast software interrupts. I'd rather get fast softints in now and may be revisit interrupt stack later.
1.52	16-Mar-2008	uwe	Rewrite RUN_P2, RUN_P1 in asm. gcc4 is too happy to optimize away assigned-goto versions if try to do anything fancy with them (discovered by trying to wrap RUN_P2 into an "if").
1.51	27-Feb-2008	xtraeme	Remove CTL_MACHDEP_NAMES, it's not used anywhere. Ok by martin@.
1.50	07-Jan-2008	uwe	branches: 1.50.2; 1.50.6; Now that sh3 has didicated interrupt stack we can check for cpu_intr_p with simple sp comparison, so we can drop ci_idepth.
1.49	14-Dec-2007	uwe	Use dedicated interrupt stack. Tested on hpcsh and landisk. This has been sitting in my tree for quite a while. While here s/top/bottom/ in a few places related to stacks to confirm to conventional terminology.
1.48	03-Dec-2007	ad	branches: 1.48.2; 1.48.6; Interrupt handling changes, in discussion since February: - Reduce available SPL levels for hardware devices to none, vm, sched, high. - Acquire kernel_lock only for interrupts at IPL_VM. - Implement threaded soft interrupts.
1.47	17-Oct-2007	garbled	branches: 1.47.2; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

(cf. gmcgarry_ctxsw) 2. implement idle lwp. 3. clean up related MD/MI interfaces. 4. make scheduler(s) modular.
1.43	16-Feb-2007	ad	branches: 1.43.2; 1.43.6; 1.43.8; 1.43.14; Remove spllowersoftclock() and CLKF_BASEPRI(), and always dispatch callouts via a soft interrupt. In the near future, softclock will be run from process context.

1.35	22-Sep-2004	yamt	move some per-cpu data definitions to MI place so that they can be modified without touching all ports. discussed on tech-kern@.
1.34	24-Mar-2004	wiz	Move (c) TNF line from 4-clause UCB to 3-clause UCB license; in other words, remove UCB's ad clause from the license TNF grants. There is no point in TNF demanding that UCB's ad clause be followed when even UCB doesn't demand it any longer. Ok'd by board@ and agc@.
1.33	04-Jan-2004	jdolecek	Rearrange process exit path to avoid need to free resources from different process context ('reaper'). From within the exiting process context: * deactivate pmap and free vmspace while we can still block * introduce MD cpu_lwp_free() - this cleans all MD-specific context (such as FPU state), and is the last potentially blocking operation; all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free() * process is now immediatelly marked as zombie and made available for pickup by parent; the remaining last lwp continues the exit as fully detached * MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same for both 'process' and 'lwp' exit uvm_lwp_exit() is modified to never block; the u-area memory is now always just linked to the list of available u-areas. Introduce (blocking) uvm_uarea_drain(), which is called to release the excessive u-area memory; this is called by parent within wait4(), or by pagedaemon on memory shortage. uvm_uarea_free() is now private function within uvm_glue.c. MD process/lwp exit code now always calls lwp_exit2() immediatelly after switching away from the exiting lwp. g/c now unneeded routines and variables, including the reaper kernel thread
1.32	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.

1.30	13-Nov-2002	msaitoh	add some definitions for P[VR]R register
1.29	07-May-2002	thorpej	branches: 1.29.6; Make CLKF_INTR() slightly less broken. The previous definition always tested true if the CPU was running in the kernel at the time of the clock interrupt, therefore all such time (kernel and idle) was counted as interrupt time. The new definition simply punts on trying to count interrupt time, which allows us to see kernel and idle time.
1.28	28-Apr-2002	uch	Use "#define<tab>", white space nits.
1.27	26-Apr-2002	msaitoh	add SH4 Processor Version Register

1.19	24-Feb-2002	uch	Move common exception vector and scheduler code to sh3/sh3/exception_vector.S and sh3/sh3/locore_subr.S. exception vectors are installed by sh_cpu_init(). machine/locore.S contains kernel entry, interrupt handler, and some MD code.
1.18	22-Feb-2002	uch	New NetBSD/sh3 clock framework. + hardclock source is moved from TMU1 to TMU0. + SH3/SH4 common kernel support. + PCLOCK estimation. + remove duplicated code.

1.10	25-Aug-2000	thorpej	Make need_resched() take a "struct cpu_info *" argument. This causes gives a primitive form of processor affinity. Its use in roundrobin() still needs some work.
1.9	07-Jun-2000	tsubai	branches: 1.9.2; Remove child_return prototype; it is now in sys/proc.h.
1.8	26-May-2000	thorpej	branches: 1.8.2; First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state: - Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future. - Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU). - Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate. - All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made. Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

1.17	06-Nov-2017	christos	Cleanup and clarify the ELFSIZE mess: We now have 2 variables automatically set in elf_machdep.h: ARCH_ELFSIZE: the size for userland binaries KERN_ELFSIZE: the size for the kernel binaries DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the same values DB_ELFSIZE used to have. In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE for the kernel and ARCH_ELFSIZE for userland. These defaults should eliminate the need for most manual ELFSIZE setting.

1.9	29-Apr-2003	scw	branches: 1.9.18; Add a BKPT_ADDR() macro which gives MD code a chance to munge a breakpoint address before it's used. Currently a no-op on all but sh5. This is useful on sh5, for example, to mask off the instruction type encoding in the bottom two address bits, and makes it possible to do "db> break $rXX" instead of manually munging the address.

Default to it for the rump disk component. No functional change for regular kernels. (The other option would've been to include dkbad in disklabels everywhere, but arguably this approach has less possible side-effects, especially given that wedges and related magic will take over the world any second now).
1.7	11-Dec-2005	christos	branches: 1.7.78; merge ktrace-lwp.
1.6	12-Jun-2005	dyoung	Make disklabel(8) and fdisk(8) into "host tools " last step: build and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel, ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/. To avoid clashes with a build-host's header files, especially on *BSD, the host-tools versions of fdisk and disklabel search for #includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h, and bootinfo.h in a new #includes namespace, nbinclude/. That is, they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>, <nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and such. I have also updated the system headers to #include from nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.
1.5	08-Oct-2003	lukem	Overhaul MBR handling (part 1): <sys/bootblock.h>: * Added definitions for the Master Boot Record (MBR) used by a variety of systems (primarily i386), including the format of the BIOS Parameter Block (BPB). This information was cribbed from a variety of sources including <sys/disklabel_mbr.h> which this is a superset of. As part of this, some data structure elements and #defines were renamed to be more "namespace friendly" and consistent with other bootblocks and MBR documentation. Update all uses of the old names to the new names. <sys/disklabel_mbr.h>: * Deprecated in favor of <sys/bootblock.h> (the latter is more "host tool" friendly). amd64 & i386: * Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to be consistent with the naming convention of the msdosfs tools. * Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1 and it's confusing to have two functionally equivalent bootblocks, especially given that "ufs" has multiple meanings (it could be a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems). * Rework pbr.S (the first sector of bootxx_): + Ensure that BPB (bytes 11..89) and the partition table (bytes 446..509) do not contain code. + Add support for booting from FAT partitions if BOOT_FROM_FAT is defined. (Only set for bootxx_msdos). + Remove "dummy" partition 3; if people want to installboot(8) these to the start of the disk they can use fdisk(8) to create a real MBR partition table... + Compile with TERSE_ERROR so it fits because of the above. Whilst this is less user friendly, I feel it's important to have a valid partition table and BPB in the MBR/PBR. Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent with other platforms. * Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that we can boot off FAT partitions. * Crank version of /usr/mdec/boot to 3.1, and fix some of the other entries in the version file. installboot(8) (i386): * Read the existing MBR of the filesystem and retain the BIOS Parameter Block (BPB) in bytes 11..89 and the MBR partition table in bytes 446..509. (Previously installboot(8) would trash those two sections of the MBR.) mbrlabel(8): * Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code to map the MBR partition type to the NetBSD disklabel type. Test built "make release" for i386, and new bootblocks verified to work (even off FAT!).

1.5	30-Sep-2025	rillig	sh3/dmacreg.h: revert snprintb change The the snprintb format strings produced nice-looking output, even though they combine the 'f' and ':' conversions, which in other cases can produce garbled output. Instead of "fixing" these particular format strings, the snprintb function should allow these variants.
1.4	29-Sep-2025	rillig	sh3/dmacreg.h: fix snprintb definitions In the previous definitions, the 'f' conversion was combined with the ':' conversion, which snprintb rejects at runtime, starting with snprintb.c 1.47 from 2024-04-07.
1.3	29-Mar-2007	uwe	Include #include <sh3/devreg.h> like other *reg.h do.

1.13	06-Nov-2017	christos	Cleanup and clarify the ELFSIZE mess: We now have 2 variables automatically set in elf_machdep.h: ARCH_ELFSIZE: the size for userland binaries KERN_ELFSIZE: the size for the kernel binaries DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the same values DB_ELFSIZE used to have. In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE for the kernel and ARCH_ELFSIZE for userland. These defaults should eliminate the need for most manual ELFSIZE setting.

1.15.50.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.15.50.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted.

1.6	28-Apr-2003	bjh21	branches: 1.6.2; Add a new feature-test macro, _NETBSD_SOURCE. If this is defined by the application, all NetBSD interfaces are made visible, even if some other feature-test macro (like _POSIX_C_SOURCE) is defined. <sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE, _POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve existing behaviour. This has two major advantages: + Programs that require non-POSIX facilities but define _POSIX_C_SOURCE can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS. + It makes most of the #ifs simpler, in that they're all now ORs of the various macros, rather than having checks for (!defined(_ANSI_SOURCE) \|\| !defined(_POSIX_C_SOURCE) \|\| !defined(_XOPEN_SOURCE)) all over the place. I've tried not to change the semantics of the headers in any case where _NETBSD_SOURCE wasn't defined, but there were some places where the current semantics were clearly mad, and retaining them was harder than correcting them. In particular, I've mostly normalised things so that _ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE, _XOPEN_SOURCE and _NETBSD_SOURCE in that order. Tested by building for vax, encouraged by thorpej, and uncontested in tech-userlevel for a week.

1.21	04-Feb-2011	uwe	__EXCEPTION_ENTRY - "tst" already does logical AND, so shave off extra "mov" and "and" and just test PSL_MD bit directly. While here - shuffle around instructions to construct PSL_MD to break dependencies. While still here - only interrupt vector uses SSR and SPC as function args, so don't bother saving them here in r4 and r5. Other vectors don't need them and interrupt vector can just as well "stc" them directly before exceptions are enabled.

1.15	17-Oct-2007	garbled	branches: 1.15.12; 1.15.16; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted.

1.11	15-Feb-2018	kamil	branches: 1.11.4; Introduce _UC_MACHINE_FP() as a macro _UC_MACHINE_FP() is a helper macro to extract from mcontext a frame pointer. Don't rely on this interface as a compiler might strip frame pointer or optimize it making this interface unreliable. For hppa assume a small frame context, for larger frames FP might be located in a different register (4 instead of 3). For ia64 there is no strict frame pointer, and registers might rotate. Reuse 79 following: ./gcc/config/ia64/ia64.h:#define HARD_FRAME_POINTER_REGNUM LOC_REG (79) Once ia64 will mature, this should be revisited. A macro can encapsulate a real function for extracting Frame Pointer on more complex CPUs / ABIs. For the remaining CPUs, reuse standard register as defined in appropriate ABI. The direct users of this macro are LLVM and GCC with Sanitizers. Proposed on tech-userlevel@. Sponsored by <The NetBSD Foundation>
1.10	12-Sep-2012	manu	branches: 1.10.32; setcontext() used to be incompatible with -lpthread since it affected the TLS pointer, therefore wrecking the pthread environement. Some ports had _UC_TLSBASE flag or equivalent (_UC_UNIQUE on alpha) that controlled whether setcontext() would change the TLS pointer. This change let libpthread override setcontext() with its own version that unsets _UC_TLSBASE, enabling safe usage of setcontext() with -lpthread. We also have the following required changes here: - rename alpha's _UC_UNIQUE into _UC_TLSBASE - add _UC_TLSBASE definition in header file for all ports (powerpc, sh3, sparc and sparc64 lack the implementation for now) - introduce a libc stub that can be overriden for setcontext() - modify MD libcs swapcontext() implementations so that they use the setcontext() libc stub instead of doing a plain system call. While we are there: - document various MD _UC_* flags in header file - add libc and libpthread tests for swapcontext() behavior (hopefully helpful to spot MD problems introduced with this change) Future work: - Deciding whether kernel support or _UC_TLSBASE should be added for powerpc, sh3, sparc and sparc64 is left to portmasters sparc64 Approved by core@
1.9	25-Feb-2011	joerg	branches: 1.9.4; Be nicer to software that insists on -ansi and use __inline.
1.8	24-Feb-2011	joerg	Allow storing and receiving the LWP private pointer via ucontext_t on all platforms except VAX and IA64. Add fast access via register for AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace the stack based pthread_self(). Implement skeleton support for Alpha, HPPA, PowerPC, SPARC and SPARC64, but leave it disabled. Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in machine/types.h and a corresponding __lwp_getprivate_fast in machine/mcontext.h. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger.
1.7	01-Jun-2008	uwe	branches: 1.7.20; 1.7.26; 1.7.28; Recycle unused _REG_EXPEVT slot in mcontext for _REG_GBR. As the size of mcontext is not changed, we avoid the hassle of versioning all the calls that use it. _REG_EXPEVT was never used by any code in the tree. Reporting EXPEVT makes sense only for signals and in that case we pass it to userland in ksi_trap already which is official MI way to get this (MD) information. Old binaries running on new kernels will now have their GBR set from new mcontext, but that's ok too, as GBR was not properly supported by old kernels (not saved in trapframe), so old binaries couldn't have possibly used it anyway.

This is a follow up of the _UC_MACHINE_FP() introduction. These tests use PRIxREGISTER, and require to be built with -D_KERNTYPES. Sponsored by <The NetBSD Foundation>

1.13	12-Jul-2023	riastradh	machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h. Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which always comes from sys/types.h. And, really, sys/types.h (or at least sys/stdint.h) is needed for uintN_t and uintptr_t.

1.11	25-Aug-2021	thorpej	branches: 1.11.4; - In kern_mutex.c, if MUTEX_CAS() is not defined, define it in terms of atomic_cas_ulong(). - For arm, ia64, m68k, mips, or1k, riscv, vax: don't define our own MUTEX_CAS(), as they either use atomic_cas_ulong() or equivalent (atomic_cas_uint() on m68k). - For alpha and sparc64, don't define MUTEX_CAS() in terms of their own _lock_cas(), which has its own memory barriers; the call sites in kern_mutex.c already have the appropriate memory barrier calls. Thus, alpha and sparc64 can use default definition. - For sh3, don't define MUTEX_CAS() in terms of its own _lock_cas(); atomic_cas_ulong() is strong-aliased to _lock_cas(), therefore defining our own MUTEX_CAS() is redundant.

Only ipl_cookie_t really needs to be exposed now, for crash(8). mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). Make inclusion of sys/intr.h explicit for spl. fix hppa and vax builds. machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in sys/types.h. avoids cpu_data.h vs sched.h include order issues. move the hppa ipl_t typedef with the moved usage of it. machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h. Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which always comes from sys/types.h. And, really, sys/types.h (or at least sys/stdint.h) is needed for uintN_t and uintptr_t. ddb: Cast pointer to uintptr_t, then to db_expr_t. Avoids warnings about conversion between pointer and integer of different size on some architectures. re-fix hppa builds. this file uses __cpu_simple_lock(), not just the underlying type, so it does need machine/lock.h. Break cycle by using `struct kmutex ' instead of `kmutex_t '. sys/sched.h included sys/mutex.h which includes sys/intr.h which includes machine/intr.h which on cats includes arm/footbridge/footbridge_intr.h which includes arm/cpu.h which includes sys/cpu_data.h which includes sys/sched.h But there was never any real need for sys/mutex.h in sys/sched.h, because it only uses pointers to the opaque struct kmutex. Cycle broken by using `struct kmutex *' instead of pulling in sys/mutex.h for the definition of kmutex_t. Side effect: This revealed that sys/cpu_data.h needed sys/intr.h (which was pulled in accidentally by sys/mutex.h via sys/sched.h) for SOFTINT_COUNT. Also revealed some other machine/cpu.h header files were missing includes of sys/mutex.h for kmutex_t. ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t. explicitly include no longer implicitly included sys/mutex.h. arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz. Sidesteps namespace collision with `#define bits ...' in net/zlib.c. complete the previous - there were two calls to find_first_bit() to fix. arm/xscale: Missed a spot with previous find_first_bit commit. evbarm/g42xxeb: Fix off-by-one in previous. The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x), which is equivalent to fls32(x) - 1, not to fls32(x). Note that fls32 is 1-based and returns 0 for x=0.
1.26	31-May-2021	simonb	Include "opt_param.h" (ifdef _KERNEL_OPT) everywhere that MSGBUFSIZE is referenced since some sources include <machine/param.h>.
1.25	01-May-2020	isaki	branches: 1.25.6; Move machine dependent AUDIO_BLK_MS default value to <machine/param.h>. If the port has __AUDIO_BLK_MS in <machine/param.h>, it will be used. Otherwise the default value (currently 10 msec) defined in audio.c will be used. This mechanism is for very old ports which cannot satisfactorily handle 10 msec block. Currently hppa, m68k, sh3, sparc(!64) and vax are. For port maintainers, if general models in your port cannot satisfactorily handle 10 msec block, please consider to define your suitable longer period (40 msec would be a good first choice). But please don't be eager to make the default value shorter. <machine/param.h> was discussed in source-changes-d. It's better than ifdef storm, or adding 60+ new header files in every arch/*/include/ directories for this. Thanks mrg@, ad@, and everyone. http://mail-index.netbsd.org/source-changes-d/2020/05/01/msg012572.html

1.21	20-Jan-2012	joerg	Change CMSG_SPACE and CMSG_LEN to provide Integer Constant Expressions again. This was changed in sys/socket.h r1.51 to work around fallout from the IPv6 aux data migration. It broke the historic ABI on some platforms. This commit restores compatibility for netbsd32 code on such platforms and provides a template for future changes to the CMSG_* alignment. Revert PCC/Clang workarounds in postfix and tmux.
1.20	08-Feb-2010	joerg	branches: 1.20.10; 1.20.14; Remove separate mb_map. The nmbclusters is computed at boot time based on the amount of physical memory and limited by NMBCLUSTERS if present. Architectures without direct mapping also limit it based on the kmem_map size, which is used as backing store. On i386 and ARM, the maximum KVA used for mbuf clusters is limited to 64MB by default. The old default limits and limits based on GATEWAY have been removed. key_registered_sb_max is hard-wired to a value derived from 2048 clusters.

This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

And remove the option from GENERIC. - It's not good idea to set such parameter in individual GENERICs. - 4msec is (probably no problem for most modern real hardware but) too aggressive to be default. - 10msec is too severe for antique machines but it's hard to draw a line. Set AUDIO_BLK_MS 40 msec on other old(slow) architectures not only m68k. Thanks tsutsui@ for comment about architecture choice. And move it from audiodef.h to audio.c as suggested by joerg@. Move machine dependent AUDIO_BLK_MS default value to <machine/param.h>. If the port has __AUDIO_BLK_MS in <machine/param.h>, it will be used. Otherwise the default value (currently 10 msec) defined in audio.c will be used. This mechanism is for very old ports which cannot satisfactorily handle 10 msec block.

1.10	06-Apr-2019	thorpej	Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe). Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.

1.37	14-Mar-2020	ad	pmap_remove_all(): Return a boolean value to indicate the behaviour. If true, all mappings have been removed, the pmap is totally cleared out, and UVM can then avoid doing the work to call pmap_remove() for each map entry. If false, either nothing has been done, or some helpful arch-specific voodoo has taken place.
1.36	03-Sep-2016	christos	branches: 1.36.16; Fix pmap_prefer for topdown and turn topdown on.
1.35	14-Nov-2010	uebayasi	branches: 1.35.18; 1.35.36; Move struct vm_page_md definition from vmparam.h to pmap.h, because it's used only by pmap. vmparam.h has definitions for wider audience. All GENERIC kernels build tested, except ia64. powerpc/include/booke/vmparam.h has one too, but it has no pmap.h, so it's left as is.
1.34	21-Oct-2009	rmind	branches: 1.34.2; 1.34.4; Remove uarea swap-out functionality: - Addresses the issue described in PR/38828. - Some simplification in threading and sleepq subsystems. - Eliminates pmap_collect() and, as a side note, allows pmap optimisations. - Eliminates XS_CTL_DATA_ONSTACK in scsipi code. - Avoids few scans on LWP list and thus potentially long holds of proc_lock. - Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k. - Removes __SWAP_BROKEN cases. Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on acorn26 (thanks to <bjh21>). Discussed on <tech-kern>, reviewed by <ad>.
1.33	09-Dec-2008	pooka	Make pmap_kernel() a MI macro for struct pmap *kernel_pmap_ptr, which is now the "API" provided by the pmap module. pmap_kernel() remains as the syntactic sugar. Bonus cosmetics round: move all the pmap_t pointer typedefs into uvm_pmap.h. Thanks to Greg Oster for providing cpu muscle for doing test builds.

Currently this is a no-op on most platforms, so they should see no difference. Reviewed by Jason.

1.9	21-Apr-2001	thorpej	pmap_update() should not be equated with "flush entire TLB", it is used to process deferred pmap operations. Since these pmaps don't defer anything, pmap_update() is a noop.

This is very bad, and e.g. caused the VM system to attempt to "clean" pages of read-only files. Only lip-services is paid to referenced attribute emulation. This could be improved.

They were all empty, except for ARM XSCALE. * Reorders the x86 PMC code not to rely on the legacy pmc.h file. The definitions are put in sysarch.h. * Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control and sys_pmc_get_info syscalls. They are marked as OBSOL in kern, netbsd32 and rump. * Removes the pmc_evid_t and pmc_ctr_t types. * Removes all the associated man pages. The sets are marked as obsolete.

In reality we are just restoring SR to its old state as no other modifications to SR can possibly happen. So return old SR and let the caller restore it in one instruction.

1.19	15-Oct-2020	mgorny	Fix the machine-dependent ptrace requests to respect LWP number Fix the machine-dependent ptrace register-related requests (e.g. PT_GETXMMREGS, PT_GETXSTATE on x86) to correctly respect the LWP number passed as the data argument. Before this change, these requests did not operate on the requested LWP of a multithreaded program. This change required moving ptrace_update_lwp() out of unit scope, and changing ptrace_machdep_dorequest() function to take a pointer to pointer as the second argument, consistently with ptrace_regs(). I am planning to extend the ATF ptrace() register tests in the future to check for regressions in multithreaded programs, as time permits. Reviewed by kamil.
1.18	14-Sep-2020	mrg	apply some parens to make macros safe. fixes GCC 9 sanitizer issues.
1.17	24-Dec-2019	kamil	Introduce PT_LWPSTATUS + PT_LWPNEXT, obsolete PT_LWPINFO PT_LWPINFO is a legacy ptrace(2) operation that was originally intended to retrieve the thread (LWP) information inside a traced process. It has a number of flaws and is confused with PT_LWPINFO from FreeBSD. PT_LWPSTATUS and PT_LWPNEXT address the problems (shortly by: rename, removal of pl_event) and introduces new features: signal context (pl_sigpend, pl_sigmask), LWP name (pl_name), LWP TLS base address (pl_private). The private pointer was so far missing information for a debugger. PT_LWPSTATUS@nnn is now shipped with core(5) files and contain LWP specific information, so far missed in the core(5) files. PT_LWPSTATUS retrieves LWP information for the prompted thread. PT_LWPNEXT retrieves LWP information for the next thread, borrowing the semantics from NetBSD specific PT_LWPINFO. PT_LWPINFO is namespaced with __LEGACY_PT_LWPINFO and still available for the foreseeable future, without plans of removing it. Add ATF tests for PT_LWPSTATUS + PT_LWPNEXT. Keep ATF tests for PT_LWPINFO. Switch GDB to new API. Proposed on tech-kern@.

Missing instruction for powerpc targets. This code is used in ATF tests (lib/libc/sys/t_ptrace_wait). Original patch by Nick Hudson, thanks!
1.13	08-Apr-2017	kamil	Add new ptrace(2) API: PT_SETSTEP & PT_CLEARSTEP These operations allow to mark thread as a single-stepping one. This allows to i.a.: - single step and emit a signal (PT_SETSTEP & PT_CONTINUE) - single step and trace syscall entry and exit (PT_SETSTEP & PT_SYSCALL) The former is useful for debuggers like GDB or LLDB. The latter can be used to singlestep a usermode kernel. These examples don't limit use-cases of this interface. Define PT_*STEP only for platforms defining PT_STEP. Add new ATF tests setstep[1234]. These ptrace(2) operations first appeared in FreeBSD. Sponsored by <The NetBSD Foundation>

1.15	26-Oct-2021	christos	Merge all MD __sigaction14_sigtramp.c copies into one: - sparc and sparc64 were not using version 0 sigcontext when there were no arguments in the signal version. This was probably a bug. - vax is using +1 the version numbers of the other archs. - Only hppa was defining __LIBC12_SOURCE__ so it was getting a working sigcontext before. all the other ports that supported sigcontext had the compat code disabled. [pointed out by thorpej, thanks!] If we want to remove sigcontext support from userland at least now there is less work to do so.

If this is defined by the application, all NetBSD interfaces are made visible, even if some other feature-test macro (like _POSIX_C_SOURCE) is defined. <sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE, _POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve existing behaviour. This has two major advantages: + Programs that require non-POSIX facilities but define _POSIX_C_SOURCE can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS. + It makes most of the #ifs simpler, in that they're all now ORs of the various macros, rather than having checks for (!defined(_ANSI_SOURCE) \|\| !defined(_POSIX_C_SOURCE) \|\| !defined(_XOPEN_SOURCE)) all over the place. I've tried not to change the semantics of the headers in any case where _NETBSD_SOURCE wasn't defined, but there were some places where the current semantics were clearly mad, and retaining them was harder than correcting them. In particular, I've mostly normalised things so that _ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE, _XOPEN_SOURCE and _NETBSD_SOURCE in that order. Tested by building for vax, encouraged by thorpej, and uncontested in tech-userlevel for a week.

1.4.6.2	16-Jan-2003	thorpej	* Include <sys/sigtypes.h> rather than <sys/signal.h> in <sys/ucontext.h>. * Define _UCONTEXT_TO_SIGCONTEXT() and _SIGCONTEXT_TO_UCONTEXT() macros for converting a ucontext -> sigcontext and back again. These macros in turn use machine-dependent macros _MCONTEXT_TO_SIGCONTEXT() and _SIGCONTEXT_TO_MCONTEXT() provided by <machine/signal.h>. The conversion process is not 100% accurate, but should be close enough. Also note that the mcontext conversion may not be enough for all platforms (m68k is a good example of this). These macros should be used only if you really know what you're doing.

Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.

1.9	21-May-2006	uwe	New stdarg.h and varargs.h based on arm and i386 versions. Use __builtin_va_* instead of hand written code in va-sh.h that uses LHS casts.

1.35	27-Aug-2015	pooka	Fix PTHREAD_FOO_INITIALIZER for C++ by not using volatile in the relevant pthread types in C++ builds, attempt 2. The problem with attempt 1 was making assumptions of what the MD __cpu_simple_lock_t (declared volatile) looks like. To get a same type except non-volatile, we change the MD type to __cpu_simple_lock_nv_t and typedef __cpu_simple_lock_t as a volatile __cpu_simple_lock_nv_t. IMO, __cpu_simple_lock_t should not be volatile at all, but changing it now is too risky. Fixes at least Rumprun w/ gcc 5.1/5.2. Furthermore, the mpd application (and possibly others) will no longer require NetBSD-specific patches. Tested: build.sh for i386, Rumprun for x86_64 w/ gcc 5.2. Based on the patch from Christos in lib/49989.
1.34	17-Jul-2011	dyoung	branches: 1.34.12; 1.34.30; Switch to new-style <sys/bus.h>.
1.33	12-Jun-2011	rmind	Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.
1.32	12-Mar-2011	joerg	branches: 1.32.2; Add TLS support for AMD64, i386 and SH3. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger.
1.31	24-Feb-2011	joerg	Allow storing and receiving the LWP private pointer via ucontext_t on all platforms except VAX and IA64. Add fast access via register for AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace the stack based pthread_self(). Implement skeleton support for Alpha, HPPA, PowerPC, SPARC and SPARC64, but leave it disabled. Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in machine/types.h and a corresponding __lwp_getprivate_fast in machine/mcontext.h. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger.
1.30	22-Dec-2010	matt	branches: 1.30.2; 1.30.4; Add a define __HAVE_CPU_DATA_FIRST which means that cpu_data is the first member in struct cpu_info.
1.29	11-Dec-2009	matt	branches: 1.29.4; Add PRIx{P,V}{ADDR,SIZE}, PRIu{P,V}SIZE, and PRIxREGISTER{,32,64} for all (except where they will be added via merge). These should be used to print {p,v}{addr,size}_t and register*_t as appropriate.
1.28	21-Oct-2009	rmind	Remove uarea swap-out functionality: - Addresses the issue described in PR/38828. - Some simplification in threading and sleepq subsystems. - Eliminates pmap_collect() and, as a side note, allows pmap optimisations. - Eliminates XS_CTL_DATA_ONSTACK in scsipi code. - Avoids few scans on LWP list and thus potentially long holds of proc_lock. - Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k. - Removes __SWAP_BROKEN cases. Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on acorn26 (thanks to <bjh21>). Discussed on <tech-kern>, reviewed by <ad>.
1.27	20-Jan-2008	joerg	branches: 1.27.10; Now that __HAVE_TIMECOUNTER and __HAVE_GENERIC_TODR are invariants, remove the conditionals and the code associated with the undef case.
1.26	17-Oct-2007	garbled	branches: 1.26.2; 1.26.8; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.25	14-Jul-2007	ad	branches: 1.25.10; Generic soft interrupts are mandatory.
1.24	24-Sep-2006	tsutsui	branches: 1.24.8; 1.24.16; Add timecounter support for SH3 ports. From gdamore on port-sh3, with several minor fixes by me. Previously sh3 ports use two timers (TMU1 and TMU2) as oneshot timer to cause real hardware interrupts by softintr(9), but now softintr(9) uses only TMU1 and TMU2 is configured as freerunning counter for timecounter(9). Tested on my dreamcast.
1.23	20-Sep-2006	uwe	Switch the rest of sh3 ports to todr(9) Split code to handle on-chip rtc into a separate driver Eliminate all todr code from clock.c Move __HAVE_GENERIC_TODR to sh3/include/types.h
1.22	11-Dec-2005	christos	branches: 1.22.20; 1.22.22; merge ktrace-lwp.

1.17	26-Sep-2003	nathanw	Move __cpu_simple_lock_t and __SIMPLELOCK_{UN,}LOCKED to machine/types.h so that they can be used in a namespace-friendly way.
1.16	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.15	28-Apr-2003	bjh21	branches: 1.15.2; Add a new feature-test macro, _NETBSD_SOURCE. If this is defined by the application, all NetBSD interfaces are made visible, even if some other feature-test macro (like _POSIX_C_SOURCE) is defined. <sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE, _POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve existing behaviour. This has two major advantages: + Programs that require non-POSIX facilities but define _POSIX_C_SOURCE can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS. + It makes most of the #ifs simpler, in that they're all now ORs of the various macros, rather than having checks for (!defined(_ANSI_SOURCE) \|\| !defined(_POSIX_C_SOURCE) \|\| !defined(_XOPEN_SOURCE)) all over the place. I've tried not to change the semantics of the headers in any case where _NETBSD_SOURCE wasn't defined, but there were some places where the current semantics were clearly mad, and retaining them was harder than correcting them. In particular, I've mostly normalised things so that _ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE, _XOPEN_SOURCE and _NETBSD_SOURCE in that order. Tested by building for vax, encouraged by thorpej, and uncontested in tech-userlevel for a week.

1.5	28-Apr-2001	kleink	branches: 1.5.2; * Move definitions of exact-width integer types from <machine/types.h> to <sys/types.h> and <sys/stdint.h>. * Add a new C99 <stdint.h> header, which provides integer types of explicit width, related limits and integer constant macros. * Extend <inttypes.h> to provide <stdint.h> definitions and format macros for printf() and scanf(). * Add C99 strtoimax() and strtoumax() functions. * Use the latter within scanf(). * Add C99 %j, %t and %z printf()/scanf() conversions for intmax_t, pointer-type and size_t arguments.

1.14	02-Nov-2016	pgoyette	branches: 1.14.16; * Split sys/kern/sys_process.c into three parts: 1 - ptrace(2) syscall for native emulation 2 - common ptrace(2) syscall code (shared with compat_netbsd32) 3 - support routines that are shared with PROCFS and/or KTRACE * Add module glue for #1 and #2. Both modules will be built-in to the kernel if "options PTRACE" is included in the config file (this is the default, defined in sys/conf/std). * Mark the ptrace(2) syscall as modular in syscalls.master (generated files will be committed shortly). * Conditionalize all remaining portions of PTRACE code on a new kernel option PTRACE_HOOKS. XXX Instead of PROCFS depending on 'options PTRACE', we should probably just add a procfs attribute to the sys/kern/sys_process.c file's entry in files.kern, and add PROCFS to the "#if defineds" for process_domem(). It's really confusing to have two different ways of requiring this file.

Move machine/stdarg.h logic into MI sys/stdarg.h and expect compiler to provide proper builtins, defaulting to the GCC interface. lint still has a special fallback. Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.
1.7	21-May-2006	uwe	New stdarg.h and varargs.h based on arm and i386 versions. Use __builtin_va_* instead of hand written code in va-sh.h that uses LHS casts. Slightly worse code is generated by gcc 3.3.3, but LHS casts are outlawed in gcc 3.3.6 and gcc 4. Build-tested on hpcsh (le) and mmeye (be), run-tested on hpcsh.

1.8	29-Apr-2001	thorpej	Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this data when pages are initialized by UVM. These macros are mandatory, but ports may #define them to nothing if they are not needed/used. This deprecates struct pmap_physseg. As a transitional measure, allow a port to #define PMAP_PHYSSEG so that it can continue to use it until its pmap is converted to use VM_MDPAGE_MEMBERS. Use all this stuff to eliminate a lot of extra work in the Alpha pmap module (it's smaller and faster now). Changes to other pmap modules will follow.

1.3	26-May-2000	thorpej	First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state: - Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future. - Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU). - Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate. - All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made. Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

1.12.6.3	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).
1.12.6.2	21-Jun-2002	thorpej	Add support for scheduler activations on SuperH. Boots multi-user on Dreamcast (SH4) with stock userland.

Makes sh4 kernel compiled with -Os actually work.

1.20.34.1	16-Jan-2013	yamt	sync with (a bit old) head
1.41	03-Aug-2020	uwe	_cpu_exception_suspend - return old SR In a typical use case we do a very short code sequence with PSL_BL set and restore the old PSL_BL value with _cpu_exception_resume that does the full read/mask/set dance. In reality we are just restoring SR to its old state as no other modifications to SR can possibly happen. So return old SR and let the caller restore it in one instruction.
1.40	18-Mar-2009	cegger	Ansify function definitions w/o arguments. Generated with sed.
1.39	28-Apr-2008	martin	branches: 1.39.8; 1.39.14; Remove clause 3 and 4 from TNF licenses
1.38	30-Mar-2007	uwe	branches: 1.38.34; 1.38.36; 1.38.38; In sh_clock_init just make sure that rtc oscillator is running, but don't start rtc, so that rtc(4) can report wall time as invalid if clock was not running on attach.
1.37	19-Oct-2006	uwe	branches: 1.37.4; 1.37.8; 1.37.10; Oops, don't stop rtc when enabling rtc oscillator - we would stall it until rtc(4) attaches and starts the clock (that caused my Jornada to lose about 12 secs during boot).
1.36	11-Oct-2006	uwe	Oops, fix bug in previous. On SH4 (two-issue) sh_clock.cpuclock is the spin count divided by two, so introduce a variable to hold the original number that we later use to compute pclock.
1.35	11-Oct-2006	uwe	Do calculations to estimate cpu and pclock using 64-bit and doing all the multiplications first. Round to nearest, instead of down. When estimating pclock don't compute sh_clock.cpucycle_1us * 1000000 sh_clock.cpuclock is exactly that (but without rounding errors). This improves timekeeping on my Jornada.
1.34	24-Sep-2006	tsutsui	Add timecounter support for SH3 ports. From gdamore on port-sh3, with several minor fixes by me. Previously sh3 ports use two timers (TMU1 and TMU2) as oneshot timer to cause real hardware interrupts by softintr(9), but now softintr(9) uses only TMU1 and TMU2 is configured as freerunning counter for timecounter(9). Tested on my dreamcast.
1.33	20-Sep-2006	uwe	Switch the rest of sh3 ports to todr(9) Split code to handle on-chip rtc into a separate driver Eliminate all todr code from clock.c Move __HAVE_GENERIC_TODR to sh3/include/types.h
1.32	05-Sep-2006	uwe	branches: 1.32.2; 1.32.4; Switch dreamcast to MI todr(9). Dreamcast does not use SuperH on-chip RTC, so do it seprately from other sh3 ports. Convert dreamcast rtc code into a real device instead of searching/attaching it manually. Tested by Nick Hudson.

1.31	19-Nov-2008	ad	branches: 1.31.4; Make the emulations, exec formats, coredump, NFS, and the NFS server into modules. By and large this commit: - shuffles header files and ifdefs - splits code out where necessary to be modular - adds module glue for each of the components - adds/replaces hooks for things that can be installed at runtime
1.30	25-Feb-2008	dholland	branches: 1.30.4; 1.30.10; 1.30.12; This code was not compiling on amd64 (is there any reason, beyond lack of demand, that it's not MI?) and it shouldn't have been compiling on sh3 either, because it was passing int * to size_t *.

1.28	17-Oct-2007	garbled	branches: 1.28.4; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.27	23-Jun-2007	dsl	branches: 1.27.8; 1.27.10; Pass TRYEMULROOT to NDINIT() instead of using CHECK_ALT_XXX. (Code is inside a big #if 0)

1.11	30-Oct-2001	thorpej	- Add a new vnode flag VEXECMAP, which indicates that a vnode has executable mappings. Stop overloading VTEXT for this purpose (VTEXT also has another meaning). - Rename vn_marktext() to vn_markexec(), and use it when executable mappings of a vnode are established. - In places where we want to set VTEXT, set it in v_flag directly, rather than making a function call to do this (it no longer makes sense to use a function call, since we no longer overload VTEXT with VEXECMAP's meaning). VEXECMAP suggested by Chuq Silvers.

1.6	20-Nov-2019	pgoyette	Move all non-emulation-specific coredump code into the coredump module, and remove all #ifdef COREDUMP conditional compilation. Now, the coredump module is completely separated from the emulation modules, and they can all be independently loaded and unloaded. Welcome to 9.99.18 !

1.9	18-Sep-2021	uwe	Do not obfuscate r0 as "reg_tmp0". Using r0 as a temp is a common choice. Some instructions _must_ use r0 as the destination (like mova or instructions with immediates). ABI uses r0 as the return register. So a helpful name is not that helpful for the former use case (temp) and is confusing for the latter two (ISA or ABI constraints). Same object code is generated.

1.7	18-Sep-2021	rin	Support __PIC__ build, in order to avoid text relocations for /usr/tests/net/in_cksum/in_cksum. Now, all the tests for in_cksum successfully pass for sh[34]. No binary changes for kernel.
1.6	18-Sep-2021	rin	cksum128mod: Prepare jump address by 'mova', instead of 'mov.l'. Since both this 'mova' and 'and #imm' above must be used against r0, we need extra 'mov r0, r3'. However, this should still be good both for sh3 and sh4: - For sh3, 'mov.l' at odd half-word address is removed; pipeline hazard due to instruction fetch is resolved. - For sh4, data cache line is no longer assigned for this 'mov.l'. Also: - Upcoming __PIC__ support (in order to avoid text relocations when built in tests/net/in_cksum) becomes simpler; no need CALL_DATUM_LOCAL() for cksum128_tail. - Shave off 4 bytes from text. No regression is observed for sh3 (hpcsh) and sh4 (landisk).

The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe). Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.

1.67	26-Oct-2022	riastradh	ddb/db_active.h: New home for extern db_active. This can be included unconditionally, and db_active can then be queried unconditionally; if DDB is not in the kernel, then db_active is a constant zero. Reduces need for #include opt_ddb.h, #ifdef DDB.
1.66	23-Feb-2021	mrg	introduce DDB_END_CMD and replace more than 20 copies of the same list of NULLs and 0. idea from rillig@. all touched ports built, several booted.
1.65	03-Aug-2020	uwe	branches: 1.65.2; SH3_P2SEG_FUNC(f) - get a P2 address of a function. Just SH3_P1SEG_TO_P2SEG + cast, but we now define SH3_P1SEG_TO_P2SEG and SH3_P2SEG_TO_P1SEG to use arithmetic, not bitwise ops. That gives the same result for the correct P1/P2 input values, but addition can be done at link time with addends. Thus SH3_P2SEG_FUNC compiles to a constant P2 address.
1.64	03-Aug-2020	uwe	db_tlbdump_cmd - get rid of RUN_P2/P1, use functions instead. Move the bits of code to read TLB entries into separate functions and call them via P2 pointers instead of doing P2/P1 switch inline.
1.63	03-Aug-2020	uwe	Declare __db_cachedump_sh3/sh4 __noinline too. Previous commit only did that for the definitions. Forgot to apply the attribute to the declarations too.
1.62	03-Aug-2020	uwe	db_cachedump_cmd - call the dump function via P2 directly. Instead of calling RUN_P2 at the very beginning of both cpu-specific cache dump functions just call them via P2 pointers. This effectively just makes db_cachedump_cmd into a shared RUN_P2 code for both of them. Drop RUN_P1 at the end as we are getting back to P1 anyway because that's where the return address is. Any necessary padding is provided by the sh_icache_sync_all() call.
1.61	28-Jan-2011	uwe	Implement PT_STEP.
1.60	26-Jan-2011	uwe	BRCR and BAMRA have different format in sh3 and sh4, so there's no point in using SH_() wrapper to refer to them in code that is already model-specific.
1.59	21-Nov-2009	rmind	branches: 1.59.4; 1.59.6; 1.59.8; Use lwp_getpcb() on mips, powerpc and sh3, clean from struct user usage.
1.58	18-Mar-2009	cegger	Ansify function definitions w/o arguments. Generated with sed.
1.57	08-Jun-2008	uwe	branches: 1.57.6; 1.57.12; Match PC address for single-stepping, program BARA = tf->tf_spc before returning from exception. Makes single-stepping work on sh3 - without matching the address sh3 gets stuck at the instruction we are at, getting EXPEVT_BREAK before executing the instruction.
1.56	07-Jun-2008	uwe	Cosmetics: add blank lines to make db_trap() call more prominent. s/kdb/ddb/ is a comment (does anyone really still calls it kdb?)
1.55	07-Jun-2008	uwe	We never pass type = -1 to kdb_trap() so g/c that cargo-culted case.
1.54	07-Jun-2008	uwe	Use _SH_TRA_BREAK instead of hardcoded constant under ifdef KGDB too.
1.53	06-Jun-2008	uwe	Support single-stepping in DDB for sh3 too, it has different format of UBC registers.
1.52	01-Jun-2008	uwe	Add GBR register to switchframe. While here, reorder switchframe so that we can shave off a few instructions when restoring it (group stack registers at the end, make sure that last and first registers are safe to load/store in delay slots).
1.51	01-Jun-2008	uwe	Add GBR register to trapframe.
1.50	22-Mar-2008	uwe	branches: 1.50.2; 1.50.4; 1.50.6; Revert interrupt stack changes. There are some issues and, at least in the current form, they complicate implementation of fast software interrupts. I'd rather get fast softints in now and may be revisit interrupt stack later.
1.49	22-Mar-2008	uwe	Oops, delete commented out line forgotten in previous.
1.48	22-Mar-2008	uwe	On SH4 we must be running on P2 to access memory-mapped TLB arrays. Print DA2 again - that messenger was shot in 1.34
1.47	15-Mar-2008	uwe	Add "mach reset" command that resets machine by taking a trap with exceptions disabled. Fix db_stackcheck_cmd (have_addr is now bool). Supply help strings for mach commands.
1.46	14-Dec-2007	uwe	branches: 1.46.2; 1.46.6; Use dedicated interrupt stack. Tested on hpcsh and landisk. This has been sitting in my tree for quite a while. While here s/top/bottom/ in a few places related to stacks to confirm to conventional terminology.
1.45	17-Oct-2007	garbled	branches: 1.45.4; 1.45.8; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.44	22-Sep-2007	martin	Add a new option DDB_VERBOSE_HELP that adds online help to ddb. From Adam Hamsik. Minor modifications by me, all bugs are probably mine.
1.43	17-May-2007	uwe	branches: 1.43.8; 1.43.10; Print pc/pr when faulting in ddb, it comes in handy.
1.42	23-Feb-2007	uwe	branches: 1.42.4; 1.42.6; 1.42.12; Sprinkle static so that gcc can eliminate simple helper functions that get inlined.
1.41	23-Feb-2007	uwe	Catch up with bool rototill.
1.40	22-Feb-2007	thorpej	TRUE -> true, FALSE -> false
1.39	21-Feb-2007	thorpej	Replace the Mach-derived boolean_t type with the C99 bool type. A future commit will replace use of TRUE and FALSE with true and false.
1.38	24-Jan-2007	hubertf	branches: 1.38.2; Remove duplicate #includes, patch contributed in private mail by Slava Semushin <slava.semushin@gmail.com>. To verify that no nasty side effects of duplicate includes (or their removal) have an effect here, I've compiled an i386/ALL kernel with and without the patch, and the only difference in the resulting .o files was in shifted line numbers in some assert() calls. The comparison of the .o files was based on the output of "objdump -D". Thanks to martin@ for the input on testing.
1.37	06-Sep-2006	uwe	branches: 1.37.2; __db_print_symbol: don't try to be too smart with db_print_loc_and_inst. We can have in a register an address that points to/into some variable in the data segment, but db_print_loc_and_inst only looks for functions, so it will misprint it as something unrelated from libkern + huge offset. E.g. instead of netbsd:cpu_info_store it would print netbsd:prop_string_create_cstring+0xdeadbeef Worse, if the address happens to be odd (char field in a struct, an element of char array), attempt at printing the "instruction" at that address will cause a fault and will abort "mach frame". Disassemly is not really that useful in "mach frame" listing anyway and more often just clutters things by overflowing 80 columns.
1.36	05-Sep-2006	uwe	Cosmetics - space auxiliary defines so that they are not visually hidden in surrounding code.
1.35	04-Sep-2006	uwe	s/0/NULL/ for pointers.
1.34	23-Aug-2006	uwe	Make columns align with the header when dumping sh4 tlb. Ifdef out dump of data array 2, it causes weird effects on landisk. Minor whitespace cosmetic.
1.33	22-Jul-2006	uwe	exp_type[] was constified in exception.c but an extern declaration in db_interface.c was not updated. Declare it publicly. While here, constify the array itself too.

Again, I'm unable to test compilation on all affected platforms, so advance apologies for potential brokenness.
1.2	25-May-2000	jhawk	Interface change: db_printsym() takes a third argument, pr, a function pointer indicating how to print the symbol. This allows db_printsym() to called in places where db_printf() is not an appropriate output function. While straightforward, apologies in advance if I've introduced any minor syntax errors; I was unable to test compilation this on all the affected platforms.
1.1	13-Sep-1999	itojun	branches: 1.1.2; Merge in NetBSD/sh3 from cvs.kame.net repository. Tree structure: - sys/arch/sh3: sh3 generic code As commented, in-chip device drivers are put into sys/arch/sh3/dev. - sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW) - sys/arch/mmeye: Brains mmEye, www.brains.co.jp MI source code includes couple of #ifdef for sh3-coff support. (sh3 uses coff or elf) Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3, to compile the tree (due to last minute tree structure change).

Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted.

1.16	08-Oct-2003	lukem	Overhaul MBR handling (part 1): <sys/bootblock.h>: * Added definitions for the Master Boot Record (MBR) used by a variety of systems (primarily i386), including the format of the BIOS Parameter Block (BPB). This information was cribbed from a variety of sources including <sys/disklabel_mbr.h> which this is a superset of. As part of this, some data structure elements and #defines were renamed to be more "namespace friendly" and consistent with other bootblocks and MBR documentation. Update all uses of the old names to the new names. <sys/disklabel_mbr.h>: * Deprecated in favor of <sys/bootblock.h> (the latter is more "host tool" friendly). amd64 & i386: * Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to be consistent with the naming convention of the msdosfs tools. * Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1 and it's confusing to have two functionally equivalent bootblocks, especially given that "ufs" has multiple meanings (it could be a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems). * Rework pbr.S (the first sector of bootxx_): + Ensure that BPB (bytes 11..89) and the partition table (bytes 446..509) do not contain code. + Add support for booting from FAT partitions if BOOT_FROM_FAT is defined. (Only set for bootxx_msdos). + Remove "dummy" partition 3; if people want to installboot(8) these to the start of the disk they can use fdisk(8) to create a real MBR partition table... + Compile with TERSE_ERROR so it fits because of the above. Whilst this is less user friendly, I feel it's important to have a valid partition table and BPB in the MBR/PBR. Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent with other platforms. * Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that we can boot off FAT partitions. * Crank version of /usr/mdec/boot to 3.1, and fix some of the other entries in the version file. installboot(8) (i386): * Read the existing MBR of the filesystem and retain the BIOS Parameter Block (BPB) in bytes 11..89 and the MBR partition table in bytes 446..509. (Previously installboot(8) would trash those two sections of the MBR.) mbrlabel(8): * Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code to map the MBR partition type to the NetBSD disklabel type. Test built "make release" for i386, and new bootblocks verified to work (even off FAT!).

(Some old mmeyes have "the bootstrap kernel to load kernel from disks" on their flash ROMs and it is not easy to update kernels on the ROMs.) - While here, use leXXtoh() to read some values in MBR.

This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted.

1.3	15-Nov-2002	manu	Add a realcode argument to trace_enter and ktrsyscall. realcode is the original system call number, which can be negative for a Mach trap. We cannot just replace code by realcode, because ktrsyscall uses it as an index in the system call table, thus crashing the kernel when the value is negative.

1.2.4.6	07-Jan-2003	thorpej	In the SA universe, the switch-to-this-LWP decision is made at a different level than where preempt() calls are made, which renders the "newlwp" argument useless. Replace it with a "more work to do" boolean argument. Returning to userspace preempt() calls pass 0. "Voluntary" preemptions in e.g. uiomove() pass 1. This will be used to indicate to the SA subsystem that the LWP is not yet finished in the kernel. Collapse the SA vs. non-SA cases of preempt() together, making the conditional code block much smaller, and don't call sa_preempt() if more work is to come. NOTE: THIS IS NOT A COMPLETE FIX TO THE preempt()-in-uiomove() PROBLEM THAT CURRENTLY EXISTS FOR SA PROCESSES.

1.2.4.3	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.46.12.4	30-Jun-2008	wrstuden	Change how we make SA threads not generate upcalls. Instead of clearing LW_SA, use a private flag, LP_SA_NOBLOCK, that we set when we want to not generate upcalls. This means we do NOT need to lock (l) (ourselves) to set it. Adjust tests that look at LW_SA. Now, we are an upcall-generating lwp if ((l->l_flag & LW_SA) && (~l->l_pflag & LP_SA_NOBLOCK)). Introduce code pattern to set & remember this: f = ~l->l_pflag & LP_SA_NOBLOCK; l->l_pflag \|= LP_SA_NOBLOCK; ... /* f is now LP_SA_NOBLOCK if it wasn't set in l_pflag before */ l->l_pflag ^= f; I updated a lot of the trap handlers to do trap handling iff LP_SA_NOBLOCK is not set. I tried to figure out if the trap handler could be triggered for user-based faults as opposed to kernel faults to user addresses, and only look at LP_SA_NOBLOCK for the latter. Above is a result of discussions with rmind at to reduce lock twiddling. Also, per same discussions, add locking to sys_sa_preempt(). p_lock is the lock we want. Also, per same discussions, remove use of LSSUSPENDED as a thread state. We needed to use it when we were emulating the 4.X and previous behavior of hiding cached threads. For the moment, we now have them instead remain visible to all and have them sleeping on the "lwpcache" wait channel. sa_newcachelwp(): sa_putcachelwp() wants savp_mutex held, not p_lock. Tweak some comments.

This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

Both modules will be built-in to the kernel if "options PTRACE" is included in the config file (this is the default, defined in sys/conf/std). * Mark the ptrace(2) syscall as modular in syscalls.master (generated files will be committed shortly). * Conditionalize all remaining portions of PTRACE code on a new kernel option PTRACE_HOOKS. XXX Instead of PROCFS depending on 'options PTRACE', we should probably just add a procfs attribute to the sys/kern/sys_process.c file's entry in files.kern, and add PROCFS to the "#if defineds" for process_domem(). It's really confusing to have two different ways of requiring this file.
1.49	04-Feb-2011	uwe	branches: 1.49.14; 1.49.32; 1.49.36; Use __INTR_MASK_EXCEPTION_UNBLOCK combo.
1.48	04-Feb-2011	uwe	__EXCEPTION_ENTRY - "tst" already does logical AND, so shave off extra "mov" and "and" and just test PSL_MD bit directly. While here - shuffle around instructions to construct PSL_MD to break dependencies. While still here - only interrupt vector uses SSR and SPC as function args, so don't bother saving them here in r4 and r5. Other vectors don't need them and interrupt vector can just as well "stc" them directly before exceptions are enabled.
1.47	28-Jan-2011	uwe	Implement PT_STEP.
1.46	20-Dec-2010	matt	branches: 1.46.2; 1.46.4; Move counting of faults, traps, intrs, soft[intr]s, syscalls, and nswtch from uvmexp to per-cpu cpu_data and move them to 64bits. Remove unneeded includes of <uvm/uvm_extern.h> and/or <uvm/uvm.h>.
1.45	23-Jan-2009	uwe	branches: 1.45.6; Revert two previous revisions and just use __pmap_kernel directly again. There's no reason to pretend we don't know what kernel_pmap_ptr is.
1.44	23-Jan-2009	uch	__pmap_kernel is pointer not symbol from pmap.c 1.68. set correct address.
1.43	09-Dec-2008	pooka	Make pmap_kernel() a MI macro for struct pmap *kernel_pmap_ptr, which is now the "API" provided by the pmap module. pmap_kernel() remains as the syntactic sugar. Bonus cosmetics round: move all the pmap_t pointer typedefs into uvm_pmap.h. Thanks to Greg Oster for providing cpu muscle for doing test builds.
1.42	08-Jun-2008	uwe	branches: 1.42.4; 1.42.6; sh_vector_generic - reorder literals to improve locality of reference.
1.41	08-Jun-2008	uwe	Match PC address for single-stepping, program BARA = tf->tf_spc before returning from exception. Makes single-stepping work on sh3 - without matching the address sh3 gets stuck at the instruction we are at, getting EXPEVT_BREAK before executing the instruction.
1.40	06-Jun-2008	uwe	Bah, got tf_ubc = 0 logic wrong in previous. Revert that part, it's bogus.
1.39	06-Jun-2008	uwe	Support single-stepping in DDB for sh3 too, it has different format of UBC registers.
1.38	28-Apr-2008	martin	branches: 1.38.2; Remove clause 3 and 4 from TNF licenses
1.37	22-Mar-2008	uwe	branches: 1.37.2; 1.37.4; Revert interrupt stack changes. There are some issues and, at least in the current form, they complicate implementation of fast software interrupts. I'd rather get fast softints in now and may be revisit interrupt stack later.
1.36	23-Feb-2008	uwe	Now that __EXCEPTION_BLOCK does the right thing, preserving SR for us, we don't have to open-code it here.
1.35	14-Feb-2008	uwe	branches: 1.35.2; 1.35.6; If we are returning from a nested interrupt we know we are returning to kernel so we can skip the PSL_MD check.
1.34	14-Dec-2007	uwe	Use dedicated interrupt stack. Tested on hpcsh and landisk. This has been sitting in my tree for quite a while. While here s/top/bottom/ in a few places related to stacks to confirm to conventional terminology.
1.33	17-Oct-2007	garbled	branches: 1.33.2; 1.33.4; 1.33.8; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.32	25-Sep-2007	uwe	sh_vector_interrupt - while here, shave off a few cycles and run with exceptions disabled only the code that really needs to.
1.31	24-Sep-2007	uwe	Do RAS check in sh_vector_interrupt, don't abuse ast() for that.
1.30	20-Aug-2007	uwe	branches: 1.30.2; 1.30.4; Add back comma between operands lost in s/tab/space/ cosmetics of 1.21 (as(1) doesn't mind, apparently)
1.29	18-May-2007	uwe	branches: 1.29.4; 1.29.8; Implement fast path TLB miss handling. Walk the page table without creating a trapframe, with exceptions disabled and using only BANK1 registers. If a valid pte is found, load it and return. Otherwise create a trapframe and proceed to the full-blown C handler.
1.28	18-Mar-2007	uwe	branches: 1.28.4; Don't do curupte checks if the miss address is in user space.
1.27	17-Mar-2007	uwe	Shave off few instructions when doing ldtlb.
1.26	17-Mar-2007	uwe	Cosmetic - fix local label name to match the name of the var it refers.
1.25	16-Mar-2007	uwe	Use dt to loop over md_upte in sh3_vector_tlbmiss. Saves a few instructions.
1.24	15-Mar-2007	uwe	Comment sh3_vector_tlbmiss. Same object code is generated.
1.23	15-Mar-2007	uwe	Arrange for data blocks to start on 32B cache line boundary.
1.22	15-Mar-2007	uwe	Use .L* for local labels. Misc cosmetic. Same object code is generated.
1.21	14-Mar-2007	uwe	branches: 1.21.2; s/TAB/space/ to separate instruction operands. There are quite a few cpp macros and long src operands anyway that destroy any intended "neatly lined up" effect that TAB was supposed to achieve. White space change only, same object code is generated, but it is much easier on the eyes now.
1.20	21-Sep-2006	uwe	branches: 1.20.2; 1.20.4; 1.20.8; 1.20.10; 1.20.12; Don't truncate TEA when we call tlb_exception from sh_vector_generic.
1.19	22-Aug-2006	uwe	branches: 1.19.2; 1.19.4; Follow up to revision 1.16 (that only dealt with sh3). Pass untruncated va=TEA to tlb_exception() from sh4_vector_tlbmiss too.
1.18	08-Feb-2006	uwe	branches: 1.18.2; sh3_vector_tlbmiss: don't waste perfectly good delay slots.
1.17	08-Feb-2006	uwe	While here, shave off few bytes and few cycles off of the sh3_vector_tlbmiss. Since the registers we use are at the very end of address space, we can load their addresses as small immediate negative constants instead of loading them from memory.
1.16	07-Feb-2006	uwe	Pass untruncated va=TEA to tlb_exception(), not its VPN.
1.15	22-Jan-2006	uwe	branches: 1.15.2; 1.15.4; Use macros from <machine/asm.h>. Provide .size Provide LINTSTUBs.
1.14	11-Dec-2005	christos	branches: 1.14.2; merge ktrace-lwp.
1.13	24-Nov-2003	uwe	branches: 1.13.16; Cosmetic: in sh_vector_generic use named label instead of numeric label for the curlwp address. Same object code is generated.
1.12	24-Nov-2003	uwe	Add __KERNEL_RCSID.
1.11	24-Nov-2003	uwe	Pass TEA to general_exception. While here add a couple of comments.

1.6	28-Mar-2002	uch	add uvmexp.intrs++
1.5	24-Mar-2002	uch	Rework interrupt code. + Fully utilize SH SR.I[0:3] interrupt level. + software interrupt is emulated by TMU1, 2 one shot interrupt. + implement generic soft interrupts. + implement clockframe correctly.
1.4	17-Mar-2002	uch	cosmetic changes, fix comments.
1.3	17-Mar-2002	uch	kernel stack fix. old code simply P3 address converted to P1, it caused memory destruction when kernel stack grow over 1 page. new code use P3 address for kernel stack. but for the sake of debug, P1 kernel stack mode remain.
1.2	28-Feb-2002	uch	branches: 1.2.2; 1.2.8; Change foo_r0_r1 macro in sh3/locore.h to foo(Rn, Rm)
1.1	24-Feb-2002	uch	Move common exception vector and scheduler code to sh3/sh3/exception_vector.S and sh3/sh3/locore_subr.S. exception vectors are installed by sh_cpu_init(). machine/locore.S contains kernel entry, interrupt handler, and some MD code.

1.9.6.2	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

1.21	06-Apr-2019	thorpej	Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe). Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives. Welcome to NetBSD 8.99.37.
1.20	14-Jan-2011	rmind	branches: 1.20.60; Retire struct user, remove sys/user.h inclusions. Note sys/user.h header as obsolete. Remove USER_TO_UAREA/UAREA_TO_USER macros. Various #include fixes and review by matt@.

1.17	01-Jun-2008	uwe	Add GBR register to switchframe. While here, reorder switchframe so that we can shave off a few instructions when restoring it (group stack registers at the end, make sure that last and first registers are safe to load/store in delay slots).
1.16	01-Jun-2008	uwe	Add GBR register to trapframe.

1.24	22-Mar-2008	uwe	Revert interrupt stack changes. There are some issues and, at least in the current form, they complicate implementation of fast software interrupts. I'd rather get fast softints in now and may be revisit interrupt stack later.
1.23	07-Jan-2008	uwe	branches: 1.23.6; Add endif comment for __HAVE_FAST_SOFTINTS.

1.19	24-Sep-2006	tsutsui	Add timecounter support for SH3 ports. From gdamore on port-sh3, with several minor fixes by me. Previously sh3 ports use two timers (TMU1 and TMU2) as oneshot timer to cause real hardware interrupts by softintr(9), but now softintr(9) uses only TMU1 and TMU2 is configured as freerunning counter for timecounter(9). Tested on my dreamcast.

1.9	18-Oct-2003	uwe	Make intc_intr_priority() return old level. While here, make the code more compact by factoring out register update to happen in one place, outside the switch statements. Add intc_intr_disable() and intc_intr_enable().
1.8	08-Oct-2003	uwe	Add IPR mappings for remaining sh7709 IRQx. While here, fix couple of typos.
1.7	08-Aug-2003	uwe	Add more sh7709 interrupt sources. Split sh3 and sh4 specific switches because of conflicts in exception codes.
1.6	15-Jul-2003	lukem	__KERNEL_RCSID()
1.5	10-Nov-2002	tsutsui	branches: 1.5.6; Make sure to stop timer count before writing timer counter registers in tmu[12]_oneshot(). Otherwise sometimes interrupts would be lost.

This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.32	30-Jun-2020	maxv	Make copystr() a MI C function, part of libkern and shared on all architectures. Notes: - On alpha and ia64 the function is kept but gets renamed locally to avoid symbol collision. This is because on these two arches, I am not sure whether the ASM callers do not rely on fixed registers, so I prefer to keep the ASM body for now. - On Vax, only the symbol is removed, because the body is used from other functions. - On RISC-V, this change fixes a bug: copystr() was just a wrapper around strlcpy(), but strlcpy() makes the operation less safe (strlen on the source beyond its size). - The kASan, kCSan and kMSan wrappers are removed, because now that copystr() is in C, the compiler transformations are applied to it, without the need for manual wrappers. Could test on amd64 only, but should be fine.

1.61	15-Jul-2021	rin	For cpu_switchto(), inherit PSL_IMASK field of SR between lwp's. Otherwise, IPL is lost during context switch, which allows improper interrupts when, e.g., spin mutexes are hold. With this fix, full ATF is successfully completed on DIAGNOSTIC kernel (with one KASSERT in uvm_map.c, which triggers kern/51254, converted to printf). Thanks uwe@ for review and suggesting optimization. Also thanks ad@ for useful comment, and ryo@ for giving me reference manuals of SH-4!

1.1.2.3	11-Feb-2001	bouyer	Sync with HEAD.
1.1.2.2	18-Jan-2001	bouyer	Sync with head (for UBC+NFS fixes, mostly).
1.1.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.30	12-Jun-2011	rmind	Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.
1.29	08-Feb-2011	rmind	branches: 1.29.2; Remove clause 3 (UCB advertising clause) from the University of Utah copyright. Confirmed by Mike Hibler, mike at cs.utah.edu - thanks! Also, merge UCB and Utah copyright texts back into one, as they originally were. Extra verification by snj@.
1.28	10-Nov-2010	uebayasi	branches: 1.28.2; 1.28.4; Use more VM_PHYSMEM_*() accessors. No functional changes.
1.27	06-Nov-2010	uebayasi	Machine dependent code is considered as part of UVM. Include internal API header.
1.26	04-Mar-2007	christos	branches: 1.26.40; 1.26.64; 1.26.66; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.25	22-Feb-2007	thorpej	TRUE -> true, FALSE -> false
1.24	21-Feb-2007	thorpej	Replace the Mach-derived boolean_t type with the C99 bool type. A future commit will replace use of TRUE and FALSE with true and false.
1.23	26-Dec-2006	elad	branches: 1.23.2; Make machdep scope architecture-agnostic by removing all arch-specific requests and centralizing them all. The result is that some of these are not used on some architectures, but the documentation was updated to reflect that.
1.22	22-Dec-2006	elad	Add requests indicating access to unmanaged memory for arm, pc532, powerpc, sh3, sh5, and vax, and use them instead of KAUTH_GENERIC_ISSUSER. Update documentation and example secmodel code.
1.21	23-Jul-2006	ad	branches: 1.21.4; 1.21.8; Use the LWP cached credentials where sane.
1.20	14-May-2006	elad	integrate kauth.
1.19	11-Dec-2005	christos	branches: 1.19.4; 1.19.6; 1.19.8; 1.19.10; 1.19.12; merge ktrace-lwp.
1.18	24-Mar-2004	wiz	branches: 1.18.16; Move (c) TNF line from 4-clause UCB to 3-clause UCB license; in other words, remove UCB's ad clause from the license TNF grants. There is no point in TNF demanding that UCB's ad clause be followed when even UCB doesn't demand it any longer. Ok'd by board@ and agc@.
1.17	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.16	15-Jul-2003	lukem	__KERNEL_RCSID()
1.15	14-Jun-2003	tsutsui	branches: 1.15.2; mmap(2) function on sh3 should return page number, not physical address.
1.14	02-Apr-2003	thorpej	Use PAGE_SIZE rather than NBPG.
1.13	23-Oct-2002	jdolecek	merge kqueue branch into -current kqueue provides a stateful and efficient event notification framework currently supported events include socket, file, directory, fifo, pipe, tty and device changes, and monitoring of processes and signals kqueue is supported by all writable filesystems in NetBSD tree (with exception of Coda) and all device drivers supporting poll(2) based on work done by Jonathan Lemon for FreeBSD initial NetBSD port done by Luke Mewburn and Jason Thorpe
1.12	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.11	09-May-2002	uch	branches: 1.11.2; 1.11.6; suitable for SH3/SH4 memory architecture. support non-contiguos memory banks.
1.10	07-May-2002	thorpej	Fix reading values mapped in P1 via /dev/kmem (problem uncovered by uch's new pmap).
1.9	27-Feb-2002	christos	- Use DEV_ constants, instead of documenting the numbers! - Delete cdev_decl(mm); where appropriate, and other hand-crufting [hi powerpc!]
1.8	12-Feb-2002	uch	ANSIfy KNF.
1.7	10-Sep-2001	chris	Update pmap_update to now take the updated pmap as an argument. This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment. Currently this is a no-op on most platforms, so they should see no difference. Reviewed by Jason.
1.6	24-Apr-2001	thorpej	branches: 1.6.2; 1.6.4; Sprinkle pmap_update() calls after calls to: - pmap_enter() - pmap_remove() - pmap_protect() - pmap_kenter_pa() - pmap_kremove() as described in pmap(9). These calls are relatively conservative. It may be possible to optimize these a little more.
1.5	29-Jun-2000	mrg	branches: 1.5.2; remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.4	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
1.3	04-Dec-1999	ragge	branches: 1.3.4; CL* discarding.
1.2	13-Nov-1999	thorpej	Update for pmap_enter() API change. No functional difference.

1.11.6.3	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

1.26.66.1	18-Mar-2010	rmind	Unify /dev/{mem,kmem,zero,null} implementations in MI code. Based on patch from Joerg Sonnenberger, proposed on tech-kern@, in February 2008. Work and depression still in progress.
1.26.64.3	30-Oct-2010	uebayasi	Implement pmap_physload_device(9) to replace xmd(4) MD backend. Implement pmap_mmap(9) and use it from mem(4) and xmd(4).

1.26.64.1	28-Apr-2010	uebayasi	Always use struct vm_physseg *vm_physmem_ptrs[] in MD code.
1.26.40.1	29-Mar-2008	mjf	Add a mem_init() function for each architecture that requests a device node for /dev/mem, /dev/null, /dev/zero, etc. This will disappear when I move this code (and others) to be a pseudo-device. When we have machine-independent mem code this will all be unnecessary anyway.

This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.21	04-Aug-2020	uwe	Avoid inline RUN_P2 when accessing TLB via memory mapped arrays. Move code that needs to run from P2 into separate functions and call them via P2 pointer.
1.20	03-Aug-2020	uwe	sh4_mmu_start - cosmetics. Split construction of the initial MMUCR value into several assignments for readability. Same object code is generated.
1.19	03-Aug-2020	uwe	sh4_mmu_start - call sh4_tlb_invalidate_all directly.
1.18	03-Aug-2020	uwe	sh4_tlb_invalidate_addr - refactor to avoid RUN_P2. Introduce __sh4_tlb_assoc that performs the associative write. Call it from sh4_tlb_invalidate_addr. In sh4_tlb_update do not call sh4_tlb_invalidate_addr, call __sh4_tlb_assoc directly. We need to do the song and dance to block exceptions and set PTEH anyway for the new value, so don't waste all that effort.
1.17	03-Aug-2020	uwe	sh4_tlb_invalidate_addr - use the right constant. VPN mask happens to be the same in many registers, but since we are writing the value to UTLB data array, use that particular constant for consistency. Same object code is generated.
1.16	03-Aug-2020	uwe	Split compound assertion into several, one for each term.
1.15	03-Aug-2020	uwe	_cpu_exception_suspend - return old SR In a typical use case we do a very short code sequence with PSL_BL set and restore the old PSL_BL value with _cpu_exception_resume that does the full read/mask/set dance. In reality we are just restoring SR to its old state as no other modifications to SR can possibly happen. So return old SR and let the caller restore it in one instruction.

1.86	02-Sep-2021	rin	PR port-sh3/56381 pmap_enter() returns ENOMEM if __pmap_pte_alloc() fails and PMAP_CANFAIL flag is specified. In this case, remove pv via __pmap_pv_remove() if it is added to p-v map list via __pmap_pv_enter(). Otherwise, pmap becomes an inconsistent state, which results in an infinite loop in pmap_page_protect(), as reported in the PR. Also, KASSERT's are added for sure, in order to detect the infinite loops. Great thanks to chs@ for finding out this bug!!

In future, these pmaps should be rewritten to handle such read only shared mappings properly like ARM pmap, but currently we just disable sosend_loan() to avoid unnecessary uncached mappings and cache flushes on MIPS3 CPUs, or map/unmap thrashing on SH4.

1.50	30-Dec-2003	pk	branches: 1.50.16; Replace the traditional buffer memory management -- based on fixed per buffer virtual memory reservation and a private pool of memory pages -- by a scheme based on memory pools. This allows better utilization of memory because buffers can now be allocated with a granularity finer than the system's native page size (useful for filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation of virtual to physical memory mappings (due to the former fixed virtual address reservation) resulting in better utilization of MMU resources on some platforms. Finally, the scheme is more flexible by allowing run-time decisions on the amount of memory to be used for buffers. On the other hand, the effectiveness of the LRU queue for buffer recycling may be somewhat reduced compared to the traditional method since, due to the nature of the pool based memory allocation, the actual least recently used buffer may release its memory to a pool different from the one needed by a newly allocated buffer. However, this effect will kick in only if the system is under memory pressure.

1.44	08-May-2003	thorpej	Simplify the way the bounds of the managed kernel virtual address space is advertised to UVM by making virtual_avail and virtual_end first-class exported variables by UVM. Machine-dependent code is responsible for initializing them before main() is called. Anything that steals KVA must adjust these variables accordingly. This reduces the number of instances of this info from 3 to 1, and simplifies the pmap(9) interface by removing the pmap_virtual_space() function call, and removing two arguments from pmap_steal_memory(). This also eliminates some kludges such as having to burn kernel_map entries on space used by the kernel and stolen KVA. This also eliminates use of VM_{MIN,MAX}_KERNEL_ADDRESS from MI code, this giving MD code greater flexibility over the bounds of the managed kernel virtual address space if a given port's specific platforms can vary in this regard (this is especially true of the evb* ports).

1.34	08-Mar-2002	thorpej	Pool deals fairly well with physical memory shortage, but it doesn't deal with shortages of the VM maps where the backing pages are mapped (usually kmem_map). Try to deal with this: * Group all information about the backend allocator for a pool in a separate structure. The pool references this structure, rather than the individual fields. * Change the pool_init() API accordingly, and adjust all callers. * Link all pools using the same backend allocator on a list. * The backend allocator is responsible for waiting for physical memory to become available, but will still fail if it cannot callocate KVA space for the pages. If this happens, carefully drain all pools using the same backend allocator, so that some KVA space can be freed. * Change pool_reclaim() to indicate if it actually succeeded in freeing some pages, and use that information to make draining easier and more efficient. * Get rid of PR_URGENT. There was only one use of it, and it could be dealt with by the caller. From art@openbsd.org.

1.28	19-Sep-2001	chs	Fix kern/13049: missing unlock on failure exit from pmap_enter()
1.27	15-Sep-2001	chs	a whole bunch of changes to improve performance and robustness under load: - remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places. The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.
1.26	10-Sep-2001	chris	Update pmap_update to now take the updated pmap as an argument. This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment. Currently this is a no-op on most platforms, so they should see no difference. Reviewed by Jason.

1.19	25-Apr-2001	thorpej	Work around the problem that causes kern/12554. Basically, there are some pathological cases that cause pmap_page_protect() to be called on a wired page to revoke all mappings.

We need to prevent the pathological behavior from happening in UVM to begin with. But it's unclear what the right solution is there, right now.

Before this change, these requests did not operate on the requested LWP of a multithreaded program. This change required moving ptrace_update_lwp() out of unit scope, and changing ptrace_machdep_dorequest() function to take a pointer to pointer as the second argument, consistently with ptrace_regs().

1.22	20-Nov-2019	pgoyette	Move all non-emulation-specific coredump code into the coredump module, and remove all #ifdef COREDUMP conditional compilation. Now, the coredump module is completely separated from the emulation modules, and they can all be independently loaded and unloaded. Welcome to 9.99.18 !
1.21	02-Nov-2016	pgoyette	branches: 1.21.16; 1.21.20; * Split sys/kern/sys_process.c into three parts: 1 - ptrace(2) syscall for native emulation 2 - common ptrace(2) syscall code (shared with compat_netbsd32) 3 - support routines that are shared with PROCFS and/or KTRACE * Add module glue for #1 and #2. Both modules will be built-in to the kernel if "options PTRACE" is included in the config file (this is the default, defined in sys/conf/std). * Mark the ptrace(2) syscall as modular in syscalls.master (generated files will be committed shortly). * Conditionalize all remaining portions of PTRACE code on a new kernel option PTRACE_HOOKS. XXX Instead of PROCFS depending on 'options PTRACE', we should probably just add a procfs attribute to the sys/kern/sys_process.c file's entry in files.kern, and add PROCFS to the "#if defineds" for process_domem(). It's really confusing to have two different ways of requiring this file.

1.99	21-May-2012	martin	Calling _lwp_create() with a bogus ucontext could trigger a kernel assertion failure (and thus a crash in DIAGNOSTIC kernels). Independently discovered by YAMAMOTO Takashi and Joel Sing. To avoid this, introduce a cpu_mcontext_validate() function and move all sanity checks from cpu_setmcontext() there. Also untangle the netbsd32 compat mess slightly and add a cpu_mcontext32_validate() cousin there. Add an exhaustive atf test case, based partly on code from Joel Sing. Should finally fix the remaining open part of PR kern/43903.

1.92	04-Mar-2011	joerg	Refactor ps_strings access. Based on PK_32, write either the normal version or the 32bit compat layout in execve1. Introduce a new function copyin_psstrings for reading it back from userland and converting it to the native layout. Refactor procfs to share most of the code with the kern.proc_args sysctl handler. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger.
1.91	24-Feb-2011	joerg	Allow storing and receiving the LWP private pointer via ucontext_t on all platforms except VAX and IA64. Add fast access via register for AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace the stack based pthread_self(). Implement skeleton support for Alpha, HPPA, PowerPC, SPARC and SPARC64, but leave it disabled. Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in machine/types.h and a corresponding __lwp_getprivate_fast in machine/mcontext.h.

Architectures without direct mapping also limit it based on the kmem_map size, which is used as backing store. On i386 and ARM, the maximum KVA used for mbuf clusters is limited to 64MB by default. The old default limits and limits based on GATEWAY have been removed. key_registered_sb_max is hard-wired to a value derived from 2048 clusters.

As the size of mcontext is not changed, we avoid the hassle of versioning all the calls that use it. _REG_EXPEVT was never used by any code in the tree. Reporting EXPEVT makes sense only for signals and in that case we pass it to userland in ksi_trap already which is official MI way to get this (MD) information. Old binaries running on new kernels will now have their GBR set from new mcontext, but that's ok too, as GBR was not properly supported by old kernels (not saved in trapframe), so old binaries couldn't have possibly used it anyway.
1.73	01-Jun-2008	uwe	Add GBR register to trapframe.

1.55	25-Apr-2005	lukem	branches: 1.55.2; Move the MI printing of `copyright' to the MD cpu_startup() code where the printing of `version' is already performed. This has the benefit of allowing the copyright to be available via dmesg(8) on platforms which need the `msgbuf' to be setup in cpu_startup() before printed output is remembered.
1.54	30-Dec-2003	pk	branches: 1.54.8; Replace the traditional buffer memory management -- based on fixed per buffer virtual memory reservation and a private pool of memory pages -- by a scheme based on memory pools. This allows better utilization of memory because buffers can now be allocated with a granularity finer than the system's native page size (useful for filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation of virtual to physical memory mappings (due to the former fixed virtual address reservation) resulting in better utilization of MMU resources on some platforms. Finally, the scheme is more flexible by allowing run-time decisions on the amount of memory to be used for buffers. On the other hand, the effectiveness of the LRU queue for buffer recycling may be somewhat reduced compared to the traditional method since, due to the nature of the pool based memory allocation, the actual least recently used buffer may release its memory to a pool different from the one needed by a newly allocated buffer. However, this effect will kick in only if the system is under memory pressure.

1.44	04-Jul-2002	thorpej	Add kernel support for having userland provide the signal trampoline: * struct sigacts gets a new sigact_sigdesc structure, which has the sigaction and the trampoline/version. Version 0 means "legacy kernel provided trampoline". Other versions are coordinated with machine- dependent code in libc. * sigaction1() grows two more arguments -- the trampoline pointer and the trampoline version. * A new __sigaction_sigtramp() system call is provided to register a trampoline along with a signal handler. * The handler is no longer passed to sensig() functions. Instead, sendsig() looks up the handler by peeking in the sigacts for the process getting the signal (since it has to look in there for the trampoline anyway). * Native sendsig() functions now select the appropriate trampoline and its arguments based on the trampoline version in the sigacts. Changes to libc to use the new facility will be checked in later. Kernel version not bumped; we will ride the 1.6C bump made recently.
1.43	23-Jun-2002	thorpej	When delivering a signal, arrange for the handler to be invoked directly. The trampoline is now used only for the return, and makes it another 2 instructions shorter.
1.42	23-Jun-2002	thorpej	When delivering a signal, don't push the signum, code, and context pointer, or handler onto the stack. Instead, just stuff them into the correct argument registers (handler is a "4th arg").

NOTE: These may collectively move into a struct schedstate at some point in the future. - Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU). - Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate. - All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made. Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

1.72.2.3	22-Jun-2008	wrstuden	Re-add cpu_upcall() and page fault code. i386 kernels now compile. They don't boot, but that seems to be a consequence of current from the day this branch was started.
1.72.2.2	14-May-2008	wrstuden	Per discussion with ad at n dot o, revert signal mask handling changes. The l_sigstk changes are most likely totally un-needed as SA will never use a signal stack - we send an upcall (or will as other diffs are brought in). The l_sigmask changes were too controvertial. In all honesty, I think it's probably best to revert them. The main reason they were there is the fact that in an SA process, we don't mask signals per kernel thread, we mask them per user thread. In the kernel, we want them all to get turned into upcalls. Thus the normal state of l_sigmask in an SA process is for it to always be empty. While we are in the process of delivering a signal, we want to temporarily mask a signal (so we don't recursively exhaust our upcall stacks). However signal delivery is rare (important, but rare), and delivering back-to-back signals is even rarer. So rather than cause every user of a signal mask to be prepared for this very rare case, we will just add a second check later in the signal delivery code. Said change is not in this diff. This also un-compensates all of our compatability code for dealing with SA. SA is a NetBSD-specific thing, so there's no need for Irix, Linux, Solaris, SVR4 and so on to cope with it. As previously, everything other than kern_sa.c compiles in i386 GENERIC as of this checkin. I will switch to ALL soon for compile testing.
1.72.2.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

Independently discovered by YAMAMOTO Takashi and Joel Sing. To avoid this, introduce a cpu_mcontext_validate() function and move all sanity checks from cpu_setmcontext() there. Also untangle the netbsd32 compat mess slightly and add a cpu_mcontext32_validate() cousin there. Add an exhaustive atf test case, based partly on code from Joel Sing. Should finally fix the remaining open part of PR kern/43903.

1.13.12.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.13.12.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.10.12.2	14-Oct-2008	wrstuden	Add a new vp-private flag, SAVP_FLAG_DELIVERING. This flag indicates that the vp is in the process of delivering a new-thread upcall. This is a BLOCKED or NEWPROC upcall. Do NOT generate any BLOCKED upcalls while this is set. Set it at the end of sa_switchcall() and clear it at syscall entry. Sadly, I have found no other way to handle this. The old SA interface has no way for userland to acknowledge that it got the upcall, so use syscall entry as the indicator that libpthread got it. This addresses the issue seen on current-users with firefox dying with a blockedgen != unbockedgen error. The problem is we deliver a BLOCKED upcall, but between the end of userret() and when the CPU indicates that it's running in user mode, we take a page fault. Said page fault blocks, blocking upcall delivery. The original block, however, was short-lived, and the UNBLOCK happens shortly. It happens before libpthread actually notices the BLOCKED upcall. Boom! Unfortunately a LOCKDEBUG/DIAGNOSTIC kernel still dies before firefox opens. However this new issue is with uvm code calling mtsleep when not holding a correct lock; sa_switch() is exploding at KASSERT(lwp_locked(l, NULL)); before it's done _anything_. Also, while here, add sa_system_disabled. This is an integer that we examine when starting SA for a proc. If it's non-zero, we error out. Once this is hooked into sysctl, you'll be able to disable SA w/o recompiling.

Also, miscellaneous cleanups in ktrace: - ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up. - move code duplicated between sys_fktrace and sys_ktrace into ktrace_common. - simplify interface to ktrwrite()
1.11	26-May-2000	thorpej	First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state: - Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future. - Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU). - Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate. - All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made. Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

1.80	06-Apr-2019	kamil	branches: 1.80.12; Centralized shared part of child_return() into MI part Add a new function md_child_return() for MD specific bits only. New child_return() is now part of MI and central code that handles uniformly tracing code (KTR and ptrace(2)). Synchronize value passed to ktrsysret() among ports to SYS_fork. This is a traditional value and accessing p_lflag to check for PL_PPWAIT shall use locking against proc_lock. Returning SYS_fork vs SYS_vfork still isn't correct enough as there are more entry points to forking code. Instead of making it too good, just settle with plain SYS_fork for all ports.

1.78	03-Apr-2019	kamil	Rework the fork(2)/vfork(2) event signalling under ptrace(2) Remove the constraint of SIGTRAP event being maskable by a tracee. Now all SIGTRAP TRAP_CHLD events are delivered to debugger. This code touches MD specific logic and the child_return routine. It's an intermediate step with a room for refactoring in future and right now the least invasive approach. This allows to assert expected behavior in already existing ATF tests and make the code prettier in future keeping the same semantics. Probably there is a need for a MI wrapper of child_return for shared functionality between ports.

Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports).

1.67	23-Apr-2010	rmind	Remove lwp_uc_pool, replace it with kmem(9), plus add some consistency. As discussed, a while ago, with ad@.
1.66	10-Dec-2009	uch	branches: 1.66.2; 1.66.4; u-area is no longer zero-cleared. reset here
1.65	29-Nov-2009	rmind	Replace l_addr with uvm_lwp_getuarea() in various MD code, mostly cpu_lwp_fork().
1.64	21-Nov-2009	rmind	Use lwp_getpcb() on mips, powerpc and sh3, clean from struct user usage.
1.63	19-Nov-2008	ad	Make the emulations, exec formats, coredump, NFS, and the NFS server into modules. By and large this commit: - shuffles header files and ifdefs - splits code out where necessary to be modular - adds module glue for each of the components - adds/replaces hooks for things that can be installed at runtime
1.62	15-Feb-2008	uwe	branches: 1.62.6; 1.62.10; 1.62.16; 1.62.18; G/c vestiges of curpute hack that was obsoleted by the fast TLB miss handler. sh3_switch_setup() has nothing to do now so don't bother calling it.
1.61	17-Oct-2007	garbled	branches: 1.61.2; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.60	27-Aug-2007	uwe	branches: 1.60.2; Move child_return() and startlwp() to be in the same file with cpu_lwp_fork() that is used to call them.
1.59	21-Aug-2007	uwe	Factor out code to setup lwp u-area into a separate function used by both cpu_lwp_fork and cpu_setfunc.
1.58	17-Aug-2007	ad	cpu_lwp_fork: don't rely on struct mdlwp being zeroed in advance.
1.57	26-May-2007	tsutsui	branches: 1.57.4; 1.57.8; Update function names in comments.
1.56	17-May-2007	yamt	merge yamt-idlelwp branch. asked by core@. some ports still needs work. from doc/BRANCHES: idle lwp, and some changes depending on it. 1. separate context switching and thread scheduling. (cf. gmcgarry_ctxsw) 2. implement idle lwp. 3. clean up related MD/MI interfaces. 4. make scheduler(s) modular.
1.55	04-Mar-2007	christos	branches: 1.55.2; 1.55.4; 1.55.10; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

1.49	11-Dec-2005	christos	branches: 1.49.2; merge ktrace-lwp.
1.48	10-Jun-2005	matt	branches: 1.48.2; Rework the coredump code to have no explicit knownledge of how coredump i/o is done. Instead, pass an opaque cookie which is then passed to a new routine, coredump_write, which does the actual i/o. This allows the method of doing i/o to change without affecting any future MD code. Also, make netbsd32_core.c [re]use core_netbsd.c (in a similar manner that core_elf64.c uses core_elf32.c) and eliminate that code duplication. cpu_coredump{,32} is now called twice, first with a NULL iocookie to fill the core structure and a second to actually write md parts of the coredump. All i/o is nolonger random access and is suitable for shipping over a stream.
1.47	01-Apr-2005	yamt	merge yamt-km branch. - don't use managed mappings/backing objects for wired memory allocations. save some resources like pv_entry. also fix (most of) PR/27030. - simplify kernel memory management API. - simplify pmap bootstrap of some ports. - some related cleanups.
1.46	09-Jan-2005	tsutsui	branches: 1.46.2; 1.46.4; Small optimization in vmapbuf()/vunmapbuf(). BTW, should we also pass 'VM_PROT_READ\|VM_PROT_WRITE' to flags with PMAP_WIRED for pmap_enter() in vmapbuf()?
1.45	17-Sep-2004	skrll	There's no need to pass a proc value when using UIO_SYSSPACE with vn_rdwr(9) and uiomove(9). OK'd by Jason Thorpe
1.44	28-Aug-2004	thorpej	Garbage-collect pagemove(); nothing use it anymore (YAY!!!)
1.43	24-Mar-2004	wiz	Move (c) TNF line from 4-clause UCB to 3-clause UCB license; in other words, remove UCB's ad clause from the license TNF grants. There is no point in TNF demanding that UCB's ad clause be followed when even UCB doesn't demand it any longer. Ok'd by board@ and agc@.
1.42	18-Jan-2004	uwe	Implement proper switch_exit in assembler. Since cpu_switch is reduced to just a call to switch_exit, g/c the C version and add a one instruction assembler version that just falls through to switch_exit. Addresses PR#24007 by Jaromir Dolecek <jdolecek@netbsd> and makes sh3 kernels work again after his elimination of the reaper. Tested on hpcsh.
1.41	06-Jan-2004	tsutsui	MD cpu_lwp_free() should have the second arg.
1.40	04-Jan-2004	jdolecek	Rearrange process exit path to avoid need to free resources from different process context ('reaper'). From within the exiting process context: * deactivate pmap and free vmspace while we can still block * introduce MD cpu_lwp_free() - this cleans all MD-specific context (such as FPU state), and is the last potentially blocking operation; all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free() * process is now immediatelly marked as zombie and made available for pickup by parent; the remaining last lwp continues the exit as fully detached * MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same for both 'process' and 'lwp' exit uvm_lwp_exit() is modified to never block; the u-area memory is now always just linked to the list of available u-areas. Introduce (blocking) uvm_uarea_drain(), which is called to release the excessive u-area memory; this is called by parent within wait4(), or by pagedaemon on memory shortage. uvm_uarea_free() is now private function within uvm_glue.c. MD process/lwp exit code now always calls lwp_exit2() immediatelly after switching away from the exiting lwp. g/c now unneeded routines and variables, including the reaper kernel thread
1.39	15-Nov-2003	uwe	Tweak KDASSERT to avoid double negation.
1.38	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.

1.30	17-Mar-2002	uch	cosmetic changes, fix comments.
1.29	17-Mar-2002	uch	kernel stack fix. old code simply P3 address converted to P1, it caused memory destruction when kernel stack grow over 1 page. new code use P3 address for kernel stack. but for the sake of debug, P1 kernel stack mode remain.
1.28	08-Mar-2002	uch	cpu_swapout() moved to cpu.h
1.27	04-Mar-2002	simonb	Don't need to declare phys_map - it is declared in <uvm/uvm_extern.h>.
1.26	03-Mar-2002	uch	SR related parts moved to psl.h. cpufunc.h segments.h are removed. kernel mode checking is only SR.MD. no check stack pointer.

1.21	16-Sep-2001	wiz	Spell 'occurred' with two 'r's.
1.20	10-Sep-2001	chris	Update pmap_update to now take the updated pmap as an argument. This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment. Currently this is a no-op on most platforms, so they should see no difference. Reviewed by Jason.
1.19	19-Aug-2001	chs	branches: 1.19.2; I was wrong, sh4 does have a VAC. change vmapbuf()/vmunmapbuf() back to using pmap_enter()/pmap_remove().
1.18	19-Aug-2001	chs	typo in previous.
1.17	19-Aug-2001	chs	use pmap_k* in vmapbuf() and vunmapbuf() since there's no VAC on this platform. in vunmapbuf(), call pmap_*remove() explicitly since uvm_km_free_wakeup() will soon no longer do it for us.
1.16	24-Jun-2001	msaitoh	branches: 1.16.2; cpu_fork() fix: - add cacheflush() when sh4 - convert kr15 from P2 area to P1 area (SH4)
1.15	02-Jun-2001	chs	replace vm_map{,_entry}_t with struct vm_map{,_entry} *.
1.14	24-Apr-2001	thorpej	Sprinkle pmap_update() calls after calls to: - pmap_enter() - pmap_remove() - pmap_protect() - pmap_kenter_pa() - pmap_kremove() as described in pmap(9). These calls are relatively conservative. It may be possible to optimize these a little more.
1.13	21-Apr-2001	thorpej	pmap_update() should not be equated with "flush entire TLB", it is used to process deferred pmap operations. Since these pmaps don't defer anything, pmap_update() is a noop.

1.9	28-May-2000	thorpej	branches: 1.9.2; Rather than starting init and creating kthreads by forking and then doing a cpu_set_kpc(), just pass the entry point and argument all the way down the fork path starting with fork1(). In order to avoid special-casing the normal fork in every cpu_fork(), MI code passes down child_return() and the child process pointer explicitly. This fixes a race condition on multiprocessor systems; a CPU could grab the newly created processes (which has been placed on a run queue) before cpu_set_kpc() would be performed.
1.8	26-Mar-2000	kleink	branches: 1.8.2; Merge parts of chs-ubc2 into the trunk: * Remove the casts to vaddr_t from the round_page() and trunc_page() macros to make them type-generic, which is necessary i.e. to operate on file offsets without truncating them. * In due course, cast pointer arguments to these macros to an appropriate integral type (paddr_t, vaddr_t). Originally done by Chuck Silvers, updated by myself.
