1.33	06-Sep-2013	tsutsui	Tab/whitespace cleanup.
1.32	07-Nov-2009	cegger	branches: 1.32.12; 1.32.22; 1.32.26; Add a flags argument to pmap_kenter_pa(9). Patch showed on tech-kern@ http://mail-index.netbsd.org/tech-kern/2009/11/04/msg006434.html No objections.
1.31	28-Apr-2008	martin	Remove clause 3 and 4 from TNF licenses
1.30	03-Oct-2006	tsutsui	branches: 1.30.52; 1.30.54; 1.30.56; - change find_prom_map() to take paddr_t and return vaddr_t rather than bus_space_handle_t since bus space handle without bus space tag looks weird - replace old sun3 obio_find_mapping() with new common find_prom_map() - add bus_space_vaddr(), from hp300
1.29	30-Sep-2006	tsutsui	Unmap pmap region in bus_mapout() as well as sun3/sun3/bus_subr.c does.
1.28	11-Dec-2005	christos	branches: 1.28.20; 1.28.22; merge ktrace-lwp.
1.27	01-Apr-2005	yamt	branches: 1.27.2; 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.
1.26	22-Jan-2005	chs	branches: 1.26.2; de-__P, remove register, ansify, b* -> mem, u_int_t -> uint*_t.
1.25	15-Jul-2003	lukem	branches: 1.25.8; __KERNEL_RCSID()
1.24	01-Apr-2003	thorpej	branches: 1.24.2; Use PAGE_SIZE rather than NBPG.
1.23	11-Sep-2001	chs	branches: 1.23.4; replace pmap_enter() with pmap_kenter_pa() where appropriate.
1.22	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.
1.21	05-Sep-2001	tsutsui	branches: 1.21.2; - vm_offset_t -> [pv]addr_t - vm_size_t -> vsize_t - remove register prefixes
1.20	24-Apr-2001	thorpej	branches: 1.20.2; 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.
1.19	14-Jan-2001	thorpej	branches: 1.19.2; splimp() -> splvm()
1.18	29-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.17	26-Jun-2000	mrg	remove/move more mach vm header files: <vm/pglist.h> -> <uvm/uvm_pglist.h> <vm/vm_inherit.h> -> <uvm/uvm_inherit.h> <vm/vm_kern.h> -> into <uvm/uvm_extern.h> <vm/vm_object.h> -> nothing <vm/vm_pager.h> -> into <uvm/uvm_pager.h> also includes a bunch of <vm/vm_page.h> include removals (due to redudancy with <vm/vm.h>), and a scattering of other similar headers.
1.16	13-Nov-1999	thorpej	Update for pmap_enter() API change. No functional difference.
1.15	26-Mar-1999	mycroft	branches: 1.15.8; 1.15.10; 1.15.14; Changes for modified pmap_enter() API: * Map the message buffer with access_type = VM_PROT_READ\|VM_PROT_WRITE `just because'. * Map the file system buffers with access_type = VM_PROT_READ\|VM_PROT_WRITE to avoid possible problems with pagemove(). * Do not use VM_PROT_EXEC with either of the above. * Map pages for /dev/mem with access_type = prot. Also, DO NOT use pmap_kenter() for this, as we DO NOT want to lose modification information. * Map pages in dumpsys() with VM_PROT_READ. * Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with access_type = prot. * For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use access_type = 0. This should probably be revisited.
1.14	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.13	09-Jun-1998	gwr	First cut at UVM support. Compiles, but not tested yet.
1.12	09-Jun-1998	gwr	Fix a warning
1.11	08-Feb-1998	gwr	Factor *peek out of bus_subr.c and move it to autoconf.c (to reduce duplication). Add bus_tmapin and bus_tmapout for use in probe functions (gets a temporary mapping). Add bus_mapout() to undo bus_mapin() if needed.
1.10	05-Feb-1998	gwr	Merge arch/sun3x into arch/sun3
1.9	16-Oct-1997	gwr	branches: 1.9.4; Add VME support
1.8	10-Jun-1997	veego	s/_trunc_page/m68k_trunc_page/
1.7	30-May-1997	jeremy	Undo changes which make pmap_xxxx_page() functions re-entrant; just block all interrupts which might cause re-entrancy. Allow virtual addresses which are not managed by the MI VM system to participate in the PV system. Remove a few frivoulous TLB cache flushes.
1.6	28-May-1997	jeremy	Coded to work with new lock system for tmp_vpages.
1.5	25-Apr-1997	gwr	Moved bus_scan() and bus_print() here from autoconf.c because they are now different in sun3 vs sun3x.
1.4	13-Mar-1997	gwr	s/sun3x_/_/ in sun3x_(round\|trunc)_(page\|seg) macros
1.3	24-Feb-1997	jeremy	branches: 1.3.2; Get rid of inclusion of pmap_pvt.h and use the standard pmap functions for mapping.
1.2	22-Feb-1997	gwr	Suport size=4 in bus_peek(), and clean out some junk.
1.1	18-Feb-1997	gwr	Move bus_peek(), bus_mapin() here from autoconf.c so the latter may be shared with the sun3 port.
1.3.2.1	12-Mar-1997	is	Merge in Changes from The Trunk.

1.45	19-Jan-2024	thorpej	Consistently use "intr_depth" as the name of the interrupt depth counter on m68k platforms.
1.44	15-Jan-2024	thorpej	Provide a m68k_count_intr() macro that hides the details of how interrupts are counted, and also ensures that ci_data.cpu_nintr is incremented.

1.35	26-Jan-2008	tsutsui	branches: 1.35.6; Also account idepth in clock interrupt handlers (which are registered directly by isr_add_custom()) and use the idepth value for CLKF_INTR().
1.34	10-Jan-2008	tsutsui	Move todr_attach(9) calls from each MD attachment to MI intersil7170_attach().
1.33	10-Jan-2008	tsutsui	- move todr_attach(9) calls from each MD attachment to MI mk48txx_attach() - don't clear todr_setwen in mk48txx_attach() since it might be set by MD attachments
1.32	04-Oct-2006	tsutsui	branches: 1.32.28; 1.32.34; 1.32.42; Make sun3 port use MI mk48txx(4) and intersil7170(4) TOD clock drivers with bus_space(9) support. Note clock device name in obio.sun3 is renamed to oclock to use the same MI attribute (intersil7170) with sun3x. Tested on 3/80 and TME emulating 3/120 (but not on 3/4xx VME monsters).

1.27	22-Sep-2003	tsutsui	branches: 1.27.8; Count clock interrupts. clock_intr() functions on sun3 are called directly without dispatchers. XXX should use evcnt(9)?
1.26	22-Sep-2003	tsutsui	KNF a bit.

1.31	01-Oct-2006	tsutsui	First attempt at bus_space(9) support for sun3 with common sun68k/bus.c: - make sun3 port use common sun68k files as much as possible - add temporary options _SUN2_ in std.sun2 until sun3 can share all sun68k files (autoconf.c and isr.c are not yet) - move sun68kvme declaration temporary as well from files.sun68k to files.sun2 - rename and move sun68k_find_prom_map() function to MD sources since it can't be shared with sun3 - add bus tag members to struct confargs and initilize them where appropriate XXX1: MD bus_dma(9) backends are not implemented (yet). XXX2: more code (obio etc.) should be shared among sun3, sun3x and sun2.

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.

1.14	13-Nov-1999	thorpej	Update for pmap_enter() API change. No functional difference.
1.13	08-Jul-1999	thorpej	branches: 1.13.2; 1.13.4; 1.13.8; Change the pmap_extract() interface to: boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *); This makes it possible for the pmap to map physical address 0.
1.12	26-Mar-1999	mycroft	branches: 1.12.4; Changes for modified pmap_enter() API: * Map the message buffer with access_type = VM_PROT_READ\|VM_PROT_WRITE `just because'. * Map the file system buffers with access_type = VM_PROT_READ\|VM_PROT_WRITE to avoid possible problems with pagemove(). * Do not use VM_PROT_EXEC with either of the above. * Map pages for /dev/mem with access_type = prot. Also, DO NOT use pmap_kenter() for this, as we DO NOT want to lose modification information. * Map pages in dumpsys() with VM_PROT_READ. * Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with access_type = prot. * For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use access_type = 0. This should probably be revisited.

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.

1.63	15-Nov-2011	tsutsui	branches: 1.63.4; Move spread getsfc() and getdfc() functions into common m68k/support.s. Note: - ENTRY_NOPROFILE() is okay since they are used only for debug printf - they are declared to return int so no need to put a return value into %a0
1.62	08-Feb-2011	rmind	branches: 1.62.4; 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@.

1.57	17-Oct-2007	garbled	branches: 1.57.20; 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.

Gcc4 > was optimizing away modifications to the frame contents (it's not nice to > trick gcc). Pass the pointer as the first argument to reduce the number > of places that would be changed otherwise. Fixes the getcwd regression > test on most m68k ports. Fixes MMU fault panic in trap() on sun3x. This should be pulled up to netbsd-4 too.
1.55	18-May-2007	tsutsui	branches: 1.55.2; 1.55.4; Adapt sun68k ports to yamt-idlelwp. Tested on TME (sun2 and sun3) and 3/80 (sun3x).

1.50	02-Nov-2002	chs	finish conversion to the common m68k cacheops: add support for machine-specific flavors of the ops for off-chip caches. many thanks to Izumi Tsutsui for his help with this.
1.49	20-Oct-2002	chs	merge the 12 copies of vm_machdep.c on the m68k platforms. clean up some other stuff along the way, including: - use m68k/cacheops.*, remove duplicates from cpu.h. - centralize a few declarations in (all the copies of) cpu.h. - define M68K_VAC on platforms which have a VAC. - switch the sun platforms to the (now common) proc_trampoline(). - do the phys_map thang on the sun platforms too, no reason not to.
1.48	22-Jul-2001	scw	branches: 1.48.6; ptest_addr() is prototyped (in pmap.c) to return a u_long not a pointer. Therefore the return value should be in %d0, not %a0.
1.47	30-May-2001	lukem	branches: 1.47.2; add missing #include "opt_kgdb.h"
1.46	12-May-2001	kleink	Update to reflect that unlike in m68k a.out environments, where the .align directive is given a log2 argument, .align is given a linear argument in m68k ELF environments.
1.45	22-Feb-2001	chs	branches: 1.45.2; switch sun3 to ELF. highlight include: add "%" prefix to register names in assembly code. change assembly functions to return values in %a0 instead of %d0. C symbols no longer prepend an underscore, adjust assembly code for this. 32-bit values are now 32-bit aligned instead of 16-bit aligned, adjust structure packing and padding to override this where necessary. make EXEC_ELF std, make EXEC_AOUT and COMPAT_AOUT_M68K optional. use the MI loadfile() instead of several home-grown versions.
1.44	26-Nov-2000	jdolecek	split m68k SunOS and SVR4-specific sigcode.s code to sunos_sigcode.s and svr4_sigcode.s respectively adjust individual m68k port's locore.s to include new sigcode files if appropriate
1.43	03-Nov-2000	tsutsui	Fix typo in the previous revision. (s/LIdle/Lidle/)
1.42	20-Aug-2000	thorpej	Add a lock around the scheduler, and use it as necessary, including in the non-MULTIPROCESSOR case (LOCKDEBUG requires it). Scheduler lock is held upon entry to mi_switch() and cpu_switch(), and cpu_switch() releases the lock before returning. Largely from Bill Sommerfeld, with some minor bug fixes and machine-dependent code hacking from me.
1.41	31-May-2000	thorpej	Add a comment on single-processor systems about p_cpu being initialized by fork1().
1.40	31-May-2000	nathanw	Update for qs -> sched_qs change. Kernel compiles again.
1.39	26-May-2000	thorpej	branches: 1.39.2; 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.
1.38	26-May-2000	thorpej	Introduce a new process state distinct from SRUN called SONPROC which indicates that the process is actually running on a processor. Test against SONPROC as appropriate rather than combinations of SRUN and curproc. Update all context switch code to properly set SONPROC when the process becomes the current process on the CPU.
1.37	26-Oct-1999	itohy	Fix the problem that single-step tracing of a trap instruction drops the system into kernel debugger.
1.36	01-Aug-1999	thorpej	branches: 1.36.2; 1.36.4; 1.36.6; Make sure the branch target of the delay loop is aligned to a cache half-line (8-byte) boundary. Inspired by a discussion w/ Scott Reynolds.

1.32	26-Feb-1999	is	sun3 part of fix for PR 6152
1.31	11-Nov-1998	thorpej	Changes to support fork_kthread(): - cpu_set_kpc() now takes void *arg third argument, passed to the entry point. - cpu_fork() allows parent to be non-curproc iff parent is proc0. When forking non-curproc, assume its state has already been saved. - Adjust various pieces of machine-dependent code to account of all of this.
1.30	30-Sep-1998	thorpej	Garbage collect trap #1 and trap #2 handlers; they're moved to trap_subr.s
1.29	30-Sep-1998	thorpej	Pull in opt_compat_netbsd.h
1.28	09-Sep-1998	thorpej	Adjust for the new "reaper" kernel thread: do not free the vmspace and u-area in machine-dependent code. Instead, call exit2() to schedule the reaper to free them for us, once it is safe to do so (i.e. we are no longer running on the dead proc's vmspace and stack).
1.27	09-Jun-1998	gwr	First cut at UVM support. Compiles, but not tested yet.
1.26	05-Feb-1998	gwr	Merge arch/sun3x into arch/sun3
1.25	22-Jan-1998	gwr	branches: 1.25.4; Separate pmap_activate() from _pmap_switch(), so the latter can remain equivalent to what locore.s:cpu_switch does with in-line assembly when PMAP_DEBUG is not defined. Also do splimp/splx in pmap_activate.
1.24	22-Jan-1998	gwr	Use MONEND instead of DVMA_SPACE_START in the "DDB convenience" symbols.
1.23	02-Jan-1998	thorpej	Make pmap_activate() take a proc *.
1.22	16-Oct-1997	gwr	MONSTART/monstart symbol

1.19	02-May-1997	jeremy	Wrap all label references with new macros in m68k/asm.h in preperation for ELF switchover. (eventually)
1.18	25-Apr-1997	gwr	Rename "Idle" to "_Idle" so clock.c can reference it.

1.11	13-Mar-1997	gwr	Sync with sun3 (Trap 1,2,15 handlers)
1.10	05-Mar-1997	gwr	Add ptest_addr
1.9	20-Feb-1997	jeremy	Added the '@' symbols that GAS needs for address register indirect addressing statements that are used when PMAP_DEBUG is undefined.
1.8	12-Feb-1997	gwr	Reinstate call to pmap_activate() for now, because it is helpful for debugging the pmap code. The in-line version of the same is still here and will be used if PMAP_DEBUG is not defined.
1.7	11-Feb-1997	gwr	Add a few more coments. (i.e. why init a6=0)

"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).

Gcc4 was optimizing away modifications to the frame contents (it's not nice to trick gcc). Pass the pointer as the first argument to reduce the number of places that would be changed otherwise. Fixes the getcwd regression test on most m68k ports. Fixes MMU fault panic in trap() on sun3x. This should be pulled up to netbsd-4 too.

1.43	13-Jan-2024	thorpej	Switch the sun68k platforms over to the common m68k vector table.
1.42	11-Jul-2020	nia	Fix various typos of "system" in comments. Mainly copypasto errors. from vezhlys on freenode.
1.41	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

1.37	27-Nov-2009	rmind	- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr. - Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb(). - Amend assembly in ports where it accesses PCB via struct user. - Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.

1.32	01-Oct-2006	tsutsui	branches: 1.32.4; First attempt at bus_space(9) support for sun3 with common sun68k/bus.c: - make sun3 port use common sun68k files as much as possible - add temporary options _SUN2_ in std.sun2 until sun3 can share all sun68k files (autoconf.c and isr.c are not yet) - move sun68kvme declaration temporary as well from files.sun68k to files.sun2 - rename and move sun68k_find_prom_map() function to MD sources since it can't be shared with sun3 - add bus tag members to struct confargs and initilize them where appropriate XXX1: MD bus_dma(9) backends are not implemented (yet). XXX2: more code (obio etc.) should be shared among sun3, sun3x and sun2.

1.129	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.
1.128	16-May-2011	tsutsui	branches: 1.128.2; - merge and move pasted m68k MD setreg() functions into m68k/m68k_machdep.c - move m68881_save() and m68881_restore() declarations into <m68k/m68k.h> Briefly tested and no obvious breakage on atari, sun3, and x68k.
1.127	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.

1.126	08-Feb-2011	rmind	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@.
1.125	17-Jan-2011	tsutsui	branches: 1.125.2; Explicitly include <machine/pcb.h> for struct pcb.
1.124	15-Oct-2010	tsutsui	branches: 1.124.2; Make common kernel module binaries work on both sun3 and sun3x. Tested on 3/160 (on TME) and (real) 3/80. XXX: module files can be loaded only on single user?
1.123	08-Feb-2010	joerg	branches: 1.123.2; 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.
1.122	10-Dec-2009	matt	branches: 1.122.2; Change u_long to vaddr_t/vsize_t in exec code where appropriate (mostly involves setregs and vmcmds). Should result in no code differences.
1.121	21-Nov-2009	rmind	Use lwp_getpcb() on sparc{64} and sun2/3 MD code, clean from struct user usage.
1.120	10-Nov-2009	he	Add a zero argument to pmap_kenter_pa() invocations. According to cegger@ this is the right thing to do for the moment.
1.119	15-Aug-2009	matt	Include <sys/exec_aout.h> explicitly instead of relying on <sys/exec.h> to do it for us.
1.118	13-Feb-2009	apb	Use "defopt MODULAR" in sys/conf/files, and #include "opt_modular.h" in all kernel sources that use the MODULAR option. Proposed in tech-kern on 18 Jan 2009.
1.117	21-Jan-2009	he	branches: 1.117.2; Re-adapt to the changed return types for major() and minor().
1.116	12-Jan-2009	tsutsui	Use PRIu64 to print 64 bit dev_t.
1.115	30-Nov-2008	martin	As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap phases, so move the initialization of the ksyms mutex back into main via a function called ksyms_init. Rename the existing (but quite different) ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit() and adapt machdep code accordingly.
1.114	25-Nov-2008	ad	dumpsys: don't spew numbers into the log.
1.113	12-Nov-2008	ad	Remove LKMs and switch to the module framework, pass 1. Proposed on tech-kern@.
1.112	11-Nov-2008	dyoung	It is not appropriate to call pmf_system_shutdown(9) from doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9) expect to be called with interrupts disabled, but shutdown hooks registered with pmf_device_register1(9) expect to be called with interrupts enabled. So I have made two changes: 1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead, change every call to doshutdownhooks() to a call to doshutdownhooks() followed by a call to pmf_system_shutdown(). No functional change is intended by this change. 2 Make i386 re-enable interrupts briefly while it calls pmf_system_shutdown(). I leave it to others either to fix the other ports, or to factor out some MI shutdown code, as joerg@ suggests, and fix that. Note that a functional change is intended by this change. I hope that this patch will stop us from flip-flopping between calling doshutdownhooks() and pmf_system_shutdown() sometimes with and sometimes without interrupts enabled.
1.111	02-Jul-2008	ad	branches: 1.111.2; 1.111.4; 1.111.6; Replce exec_map with a pool. Proposed on tech-kern@, reviewed by chs@.
1.110	17-Oct-2007	garbled	branches: 1.110.16; 1.110.20; 1.110.22; 1.110.24; 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.
1.109	02-Jun-2007	tsutsui	branches: 1.109.10; - Don't refer fputype before FPU is probed. - Call m68k_make_fpu_idle_frame() from initfpu().
1.108	04-Mar-2007	tsutsui	branches: 1.108.2; 1.108.4; 1.108.10; Use (char *) on pointer arith.
1.107	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.106	22-Feb-2007	thorpej	TRUE -> true, FALSE -> false
1.105	09-Feb-2007	ad	branches: 1.105.2; Merge newlock2 to head.
1.104	21-Oct-2006	mrg	in cpu_dumpconf(), don't panic() if we can't bdevsw_lookup() the dumpdev. this occurs when we try to set the dumpdev to a device with no driver loaded. this fixes PR#34872. in sys_swapctl, if bdevsw_lookup() fails, set dumpdev = NODEV before calling cpu_dumpconf(). (this also fixes PR#34872.) XXX: cpu_dumpconf() should probably be changed to take a dumpdev XXX: and return an error in such cases, but that is a much more XXX: intrusive change. XXX2: this is only run-tested on sparc64 and compile tested on a XXX2: couple of platforms.
1.103	05-Oct-2006	tsutsui	Make sun3 use common sun68k/sun68k/isr.c, sun68k/include/cpu.h and sun68k/include/intr.h. This also means now sun3 has GENERIC_SOFT_INTERRUPTS support, so also adapt fd.c and zs.c to MI softintr(9) APIs. (I'll also update related sources in yamt-splraiseipl branch later)
1.102	11-Dec-2005	christos	branches: 1.102.20; 1.102.22; merge ktrace-lwp.
1.101	19-Jun-2005	thorpej	branches: 1.101.2; Move common Sun ID PROM definitions into <dev/sun/idprom.h>.
1.100	03-Jun-2005	tsutsui	Constify.
1.99	25-Apr-2005	lukem	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.
1.98	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.
1.97	22-Jan-2005	chs	branches: 1.97.2; de-__P, remove register, ansify, b* -> mem, u_int_t -> uint*_t.
1.96	24-Mar-2004	atatat	branches: 1.96.8; Tango on sysctl_createv() and flags. The flags have all been renamed, and sysctl_createv() now uses more arguments.
1.95	13-Feb-2004	wiz	Uppercase CPU, plural is CPUs.
1.94	30-Dec-2003	pk	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.
1.93	04-Dec-2003	atatat	Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.
1.92	26-Oct-2003	mycroft	Fix a compiler warning.
1.91	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.
1.90	15-Jul-2003	lukem	__KERNEL_RCSID()
1.89	29-Jun-2003	fvdl	branches: 1.89.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.88	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V
1.87	26-Apr-2003	ragge	Call ksyms_init() instead of ddb_init() in case of NKSYMS \|\| defined(DDB) \|\| defined(LKM)
1.86	01-Apr-2003	thorpej	Use PAGE_SIZE rather than NBPG.
1.85	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.84	20-Oct-2002	chs	merge the 12 copies of vm_machdep.c on the m68k platforms. clean up some other stuff along the way, including: - use m68k/cacheops.*, remove duplicates from cpu.h. - centralize a few declarations in (all the copies of) cpu.h. - define M68K_VAC on platforms which have a VAC. - switch the sun platforms to the (now common) proc_trampoline(). - do the phys_map thang on the sun platforms too, no reason not to.
1.83	25-Sep-2002	thorpej	Don't include <sys/map.h>.
1.82	19-Sep-2002	ragge	Do not include <sys/clist.h>, it's not used in NetBSD at all.
1.81	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.
1.80	25-Aug-2002	thorpej	Make nbuf, nswbuf, and bufpages unsigned. Make all operations on these variables unsigned, and update places where their values are printed.
1.79	18-May-2002	lukem	add missing union sun3sir sun3sir; (hi gimpy!)
1.78	20-Mar-2002	christos	branches: 1.78.4; kill remaining PS_STRINGS instances.
1.77	06-Mar-2002	tsutsui	Change type of dumpmag to u_int32_t since it is actually a 32bit unsigned magic number. As per discussion on tech-kern, and fixes port-sparc64/11949.
1.76	11-Sep-2001	chs	branches: 1.76.4; replace pmap_enter() with pmap_kenter_pa() where appropriate.
1.75	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.
1.74	05-Sep-2001	tsutsui	branches: 1.74.2; bcopy() -> memcpy(), bzero() -> memset()
1.73	05-Sep-2001	tsutsui	- vm_offset_t -> [pv]addr_t - vm_size_t -> vsize_t - remove register prefixes
1.72	31-Aug-2001	simonb	Use comments around the token after a #endif.
1.71	16-Jun-2001	tsutsui	branches: 1.71.2; Make sure to write out the dump header into an independent block on the dump device on sun3x. (sync with sun3) Now savecore(8) can find core dump in dumpdev properly. XXX "target kcore /dev/mem" on gdb does not work yet.
1.70	02-Jun-2001	chs	replace vm_map{,_entry}_t with struct vm_map{,_entry} *.
1.69	30-May-2001	lukem	add missing #include "opt_kgdb.h"
1.68	28-May-2001	chs	remove check for too-small MSGBUFOFF now that the reason for it is gone.
1.67	28-May-2001	chs	remove a useless call to uvm_map_protect(). the kernel text is already mapped read-only in pmap_bootstrap() and the comment which tried to explain why this might be needed anyway didn't make any sense.
1.66	28-May-2001	chs	make sun3x work again after the recent change to the m68k cpu_kcore_hdr: allocate a page for dumps like the sun3 does rather than using part of the msgbuf page. this also lets the msgbuf use the full msgbuf page.
1.65	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.
1.64	15-Mar-2001	chs	eliminate the KERN_* error codes in favor of the traditional E* codes. the mapping is: KERN_SUCCESS 0 KERN_INVALID_ADDRESS EFAULT KERN_PROTECTION_FAILURE EACCES KERN_NO_SPACE ENOMEM KERN_INVALID_ARGUMENT EINVAL KERN_FAILURE various, mostly turn into KASSERTs KERN_RESOURCE_SHORTAGE ENOMEM KERN_NOT_RECEIVER <unused> KERN_NO_ACCESS <unused> KERN_PAGES_LOCKED <unused>
1.63	22-Feb-2001	chs	branches: 1.63.2; switch sun3 to ELF. highlight include: add "%" prefix to register names in assembly code. change assembly functions to return values in %a0 instead of %d0. C symbols no longer prepend an underscore, adjust assembly code for this. 32-bit values are now 32-bit aligned instead of 16-bit aligned, adjust structure packing and padding to override this where necessary. make EXEC_ELF std, make EXEC_AOUT and COMPAT_AOUT_M68K optional. use the MI loadfile() instead of several home-grown versions.
1.62	26-Jan-2001	tsutsui	Sync with sun3/machdep.c: > Require the machine-dependant DDB commands to be in db_machine_command_table[] > and link it directly to db_command_table[] so that it's not necessary > to do this at runtime. Make db_machine_command_table[] const on all ports. > g/c now unneded stuff, like db_machine_commands_install(), db_machine_init() > > Patch written by enami.
1.61	09-Nov-2000	tsutsui	On sun3x, cpu_reboot() calls sunmon_abort() for PROM bug work-around, but sunmon_abort() does not restore mon_crp so it causes problems. Instead, call romVectorPtr->abortEntry (via trap14) from sunmon_halt() and call it from cpu_reboot(). Now PROM boot command works properly even after halt on my 3/80.
1.60	13-Sep-2000	thorpej	Add an align argument to uvm_map() and some callers of that routine. Works similarly fto pmap_prefer(), but allows callers to specify a minimum power-of-two alignment of the region. How we ever got along without this for so long is beyond me.
1.59	29-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.58	26-Jun-2000	mrg	remove/move more mach vm header files: <vm/pglist.h> -> <uvm/uvm_pglist.h> <vm/vm_inherit.h> -> <uvm/uvm_inherit.h> <vm/vm_kern.h> -> into <uvm/uvm_extern.h> <vm/vm_object.h> -> nothing <vm/vm_pager.h> -> into <uvm/uvm_pager.h> also includes a bunch of <vm/vm_page.h> include removals (due to redudancy with <vm/vm.h>), and a scattering of other similar headers.
1.57	05-Jun-2000	jhawk	branches: 1.57.2; Do not clear msgbufenabled in dumpsys(). Dump messages will now go to the message buffer. This can be invaluable in debugging if the dump fails (assuming a persistant message buffer)
1.56	26-May-2000	thorpej	branches: 1.56.2; 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.
1.55	19-Jan-2000	thorpej	Move callout initialization to a single location; no need to duplicate that code all over the place.

1.53	13-Nov-1999	thorpej	Update for pmap_enter() API change. No functional difference.
1.52	12-Sep-1999	chs	branches: 1.52.2; 1.52.4; 1.52.8; eliminate the PMAP_NEW option by making it required for all ports. ports which previously had no support for PMAP_NEW now implement the pmap_k* interfaces as wrappers around the non-k versions.
1.51	26-May-1999	thorpej	Change the vm_map's "entries_pageable" member to a r/o flags member, which has PAGEABLE and INTRSAFE flags. PAGEABLE now really means "pageable", not "allocate vm_map_entry's from non-static pool", so update all map creations to reflect that. INTRSAFE maps are maps that are used in interrupt context (e.g. kmem_map, mb_map), and thus use the static map entry pool (XXX as does kernel_map, for now). This will eventually change now these maps are locked, as well.
1.50	20-May-1999	lukem	* convert to using MI allocsys(). most ports were using an MD allocsys(), although a couple still used the old pre-4.4-lite (?) mechanism. * use format_bytes() to format the various printf()s that print out memory sizes
1.49	26-Apr-1999	thorpej	Garbage-collect the VM_MBUF_SIZE constant. Instead, use the size (nmbclusters * mclbytes), so that the right amount of KVA space is allocated if those variables are patched.
1.48	25-Apr-1999	simonb	g/c REAL_CLISTS.
1.47	11-Apr-1999	chs	add a `flags' argument to uvm_pagealloc_strat(). define a flag UVM_PGA_USERESERVE to allow non-kernel object allocations to use pages from the reserve. use the new flag for allocations in pmap modules.

1.43	26-Mar-1999	mycroft	Changes for modified pmap_enter() API: * Map the message buffer with access_type = VM_PROT_READ\|VM_PROT_WRITE `just because'. * Map the file system buffers with access_type = VM_PROT_READ\|VM_PROT_WRITE to avoid possible problems with pagemove(). * Do not use VM_PROT_EXEC with either of the above. * Map pages for /dev/mem with access_type = prot. Also, DO NOT use pmap_kenter() for this, as we DO NOT want to lose modification information. * Map pages in dumpsys() with VM_PROT_READ. * Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with access_type = prot. * For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use access_type = 0. This should probably be revisited.

"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).

1.89.2.1	02-Jul-2003	darrenr	Apply the aborted ktrace-lwp changes to a specific branch. 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.

1.110.22.2	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.
1.110.22.1	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.

1.36	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.
1.35	08-Feb-2011	rmind	branches: 1.35.2; 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@.
1.34	15-Oct-2010	tsutsui	branches: 1.34.2; 1.34.4; Make common kernel module binaries work on both sun3 and sun3x. Tested on 3/160 (on TME) and (real) 3/80. XXX: module files can be loaded only on single user?

1.25	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.

1.22	10-Sep-2001	chris	branches: 1.22.4; 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	24-Apr-2001	thorpej	branches: 1.19.2; 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.

1.16	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.

Also, DO NOT use pmap_kenter() for this, as we DO NOT want to lose modification information. * Map pages in dumpsys() with VM_PROT_READ. * Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with access_type = prot. * For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use access_type = 0. This should probably be revisited.
1.11	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.

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.

1.36	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.35	24-Apr-2021	thorpej	branches: 1.35.8; 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?).

1.28	03-Oct-2006	tsutsui	- change find_prom_map() to take paddr_t and return vaddr_t rather than bus_space_handle_t since bus space handle without bus space tag looks weird - replace old sun3 obio_find_mapping() with new common find_prom_map() - add bus_space_vaddr(), from hp300
1.27	01-Oct-2006	tsutsui	First attempt at bus_space(9) support for sun3 with common sun68k/bus.c: - make sun3 port use common sun68k files as much as possible - add temporary options _SUN2_ in std.sun2 until sun3 can share all sun68k files (autoconf.c and isr.c are not yet) - move sun68kvme declaration temporary as well from files.sun68k to files.sun2 - rename and move sun68k_find_prom_map() function to MD sources since it can't be shared with sun3 - add bus tag members to struct confargs and initilize them where appropriate XXX1: MD bus_dma(9) backends are not implemented (yet). XXX2: more code (obio etc.) should be shared among sun3, sun3x and sun2.

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.

Maybe one day we can look at this again. Fixes PR kern/21517.
1.80	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).

1.74	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.

Handle unwiring page cases properly in pmap_enter(9) and pmap_remove(9). Previously sun3x pmap assumed that pmap_unwire(9) was the only interface which should handle unwiring page, but nowadays apparently it isn't true. Fixes a longstanding "panic: get_a_table: out of A tables" (and also B, C tables) problem on my 3/80. While here, make this compile with PMAP_DEBUG.

1.19	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.18	24-Apr-2021	thorpej	branches: 1.18.8; 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?).

1.17.44.3	04-Apr-2021	thorpej	CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
1.17.44.2	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.
1.17.44.1	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.
1.18.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
