Revision	Date	Author	Comments
1.25	09-Mar-2005	bouyer	Merge the bouyer-xen2 branch. This add supports for the Xen 2.0 virtual machine kernel (both privileged and non-privileged domains), and remove support for the old xen 1.2.
1.24	25-Feb-2005	simonb	Add COMPAT_20 (and COMPAT_16 in some cases) to kernel config files that didn't have those options but had other earlier compat options.
1.23	18-Feb-2005	dsl	Invert FFS_SNAPSHOT to FFS_NO_SNAPSHOT
1.22	11-Feb-2005	dsl	Add 'option FFS_SNAPSHOT' to most of the config files. Commented out for kernels that appear to hace space constraints.
1.21	31-Jan-2005	hannken	Add file system snapshots to kernel configs. - Ffs internal snapshots get compiled in unconditionally. - File system snapshot device fss(4) added to all kernel configs that have a disk. Device is commented out on all non-GENERIC kernels. Reviewed by: Jason Thorpe <thorpej@netbsd.org>
1.20	28-Jan-2005	rumble	Sprinkle options UFS_DIRHASH on GENERIC kernels. It's presently commented out and labeled experimental pending further review and testing.
1.19	17-Jan-2005	cube	branches: 1.19.2; Add tap(4) support to a random^Wcarefully chosen set of kernel configs. All those kernels have a line for both tun and bridge, and if either is commented out, tap is commented out also. With the exception of i386's GENERIC_TINY. XXX: we _need_ some way of making this more simple.
1.18	10-Nov-2004	christos	branches: 1.18.4; 1.18.6; Add COMPAT_BSDPTY to the rest of the config files.
1.17	10-Nov-2004	christos	Add COMPAT_BSDPTY on all the kernels that have COMPAT options.
1.16	23-Sep-2004	tls	Changes from Christian Limpach to improve timekeeping on NetBSD/xen by actually adjusting the time correctly (calling hardclock as needed, not just blindly every time Xen schedules us) based on Xen's idea of the time in the shared page.

1.15	04-Sep-2004	manu	IPv4 PIM support, based on a submission from Pavlin Radoslavov posted on tech-net@
1.14	15-Jul-2004	atatat	branches: 1.14.2; Add "options SYSCTL_INCLUDE_DESCR" to a lot of configs, but commented out in most of them.
1.13	26-Jun-2004	abs	Add (commented out) ALTQ options to all GENERIC-like files
1.12	18-Jun-2004	christos	ptm is now mandatory, depends on pty, and can be disabled with -DNO_DEV_PTM
1.11	16-Jun-2004	christos	Add pseudo-device ptm on all the generic flavored kernels.
1.10	07-May-2004	cl	Add support for domain0 operations: - access to all physical memory - access to hypervisor traps from userland - setup/config Xen's network routing/firewall rules
1.9	26-Apr-2004	cl	Add mouse support.
1.8	24-Apr-2004	cl	Enable keyboard and vga display as console when running as domain-0.
1.7	24-Apr-2004	cl	Add keyboard support and wscons config options.
1.6	24-Apr-2004	cl	Add vga display support.
1.5	24-Apr-2004	cl	Allow the block device driver to impersonate wd/sd/cd devices. This allows for most system seamless migration from a NetBSD/i386 setup to a NetBSD/xen setup without changing /etc/fstab or creating additional device nodes.
1.4	24-Apr-2004	cl	Consistently use xencons for eveything reffering to Xen's virtual console. rename arch/xen/xen/console.c -> arch/xen/xen/xencons.c
1.3	24-Apr-2004	cl	Add ``hypervisor at mainbus'' and attach all devices provided by the hypervisor to it instead of mainbus. rename arch/xen/i386/hypervisor.c -> arch/xen/i386/hypervisor_machdep.c
1.2	17-Apr-2004	cl	add block device driver

1.2.54.2	19-Nov-2007	bouyer	Get rid of arch/xenamd64, step 1: empty xenamd64/conf - move xenamd64/conf/std.xen to amd64/conf/ - define arch to amd64 amd64/conf/std.xen, and i386 in xen/conf/std.xen (machine is xen) - enclose content of amd64/conf/files.amd64 and i386/conf/files.i386 in ifndef xen/endif, so it can be transparently inclued for xen kernels - support MACHINE_ARCH=x86_64 in xen/conf/Makefile*
1.2.54.1	17-Oct-2007	bouyer	Prepare for xenamd64: - kill xen/i386/identcpu.c, use i386/i386/identcpu.c instead (with a few #ifndef XEN) - move some files that can be shared between i386 and amd64 from xen/i386 to xen/x86 (or to xen/xen for non-cpu-specific code) - split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h - use <xen/...> instead of <machine/...> for cpu-independant include files. more work needed here, i386-specific files should got out of arch/xen to arch/xeni386, and more code shared with arch/i386.
1.2.50.1	09-Jan-2008	matt	sync with HEAD
1.2.48.1	27-Nov-2007	joerg	Sync with HEAD. amd64 Xen support needs testing.
1.2.30.1	03-Dec-2007	ad	Sync with HEAD.
1.50	02-May-2020	bouyer	Introduce Xen PVH support in GENERIC. This is compiled in with options XENPVHVM x86 changes: - add Xen section and xen pvh entry points to locore.S. Set vm_guest to VM_GUEST_XENPVH in this entry point. Most of the boot procedure (especially page table setup and switch to paged mode) is shared with native. - change some x86_delay() to delay_func(), which points to x86_delay() for native/HVM, and xen_delay() for PVH Xen changes: - remove Xen bits from init_x86_64_ksyms() and init386_ksyms() and move to xen_init_ksyms(), used for both PV and PVH - set ISA no-legacy-devices property for PVH - factor out code from Xen's cpu_bootconf() to xen_bootconf() in xen_machdep.c - set up a specific pvh_consinit() which starts with printk() (which uses a simple hypercall that is available early) and switch to xencons when we can use pmap_kenter_pa().
1.49	25-Apr-2020	bouyer	Merge the bouyer-xenpvh branch, bringing in Xen PV drivers support under HVM guests in GENERIC. Xen support can be disabled at runtime with boot -c disable hypervisor
1.48	02-Feb-2019	cherry	branches: 1.48.10; Switch NetBSD/xen to use XEN api tag RELEASE-4.11.1 The headers for this api are in sys/external/mit/xen-include-public/dist/
1.47	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
1.46	02-Jun-2018	christos	branches: 1.46.2; disable sanitizers and relro
1.45	21-Jan-2018	maxv	branches: 1.45.2; Fix the build, on Xen too amd64_trap.S needs to be compiled independently.
1.44	12-Dec-2017	pgoyette	Remove trailing '&&' from shell script to fix the build. From a-rin on https://gist.github.com/a-rin/940abb80d45eb7ac75b8110b8466f149
1.43	10-Dec-2017	christos	- Allow multiple .BEGIN targets - Make their protection consistent
1.42	09-Aug-2017	maxv	Remove several dead entries from the x86 makefiles. Looks like people (me included) regularly forget to take care of this.
1.41	02-Feb-2017	maxv	branches: 1.41.6; Increase KERNTEXTOFF from 1MB to 2MB on amd64. [1MB; 2MB[ is now handled by UVM, so there is no physical loss. On amd64 we always remap the kernel text with 2MB pages, and because of the 1MB start address we were forced to map [0MB; 2MB[ inside the first large page. The problem is, the lower half is used by UVM to allocate physical pages, and it is possible that some of these could be used by userland. We could end up with userland-controllable data mapped into the kernel text on a privileged page, which is far from being a good idea from a security pov. I am not fixing i386 yet, because the large page size depends on PAE, and we probably don't want to have a text located at 4MB on low-memory systems. (note: I didn't introduce this issue, it was already there when I came in)
1.40	24-Aug-2015	uebayasi	branches: 1.40.2; 1.40.4; Define ${LINKSCRIPT} in one place.
1.39	18-Aug-2015	uebayasi	${KERN_LDSCRIPT} -> ${KERNLDSCRIPT}
1.38	15-Nov-2014	uebayasi	branches: 1.38.2; Use LINKSCRIPT.
1.37	20-Jul-2014	joerg	Restrict -mno-fp-ret-in-387 to GCC.
1.36	17-Jul-2014	bouyer	Sync DEFCOPTS and CFLAGS with i386 and amd64 counterparts. Especially -fno-omit-frame-pointer
1.35	19-Dec-2011	joerg	branches: 1.35.6; 1.35.20; Move Clang-warning flags for ah_regdomain.c into sys/conf, they are platform independent. Use the selective -Wno-* flags instead of -Wno-error.
1.34	17-Aug-2011	joerg	branches: 1.34.2; 1.34.6; Works with clang's integrated assembler now.
1.33	30-May-2011	joerg	Disable -Werror for ah_regdomain.c if building with clang as workaround for http://llvm.org/bugs/show_bug.cgi?id=10030.
1.32	20-May-2011	joerg	LLVM's assembler parser doesn't support .code32 yet, so disable it as needed.
1.31	12-Jan-2011	joerg	branches: 1.31.2; Allow use of traditional CPP to be set on a per platform base in sys.mk. Honour this for dependency processing in bsd.dep.mk. Switch i386 and amd64 assembly to use ISO C90 preprocessor concat and drop the -traditional-cpp on this platform.
1.30	06-Jul-2010	mrg	remove almost all the ability to build netbsd with an a.out target. we're ELF now, and there are many missing checks against OBJECT_FMT. if we ever consider switching, the we can figure out what new ones we need but for now it's just clutter. this doesn't remove any of the support for exec_aout or any actually required-for-boot a.out support, only the ability to build a netbsd release in a.out format. ie, most of this code has been dead for over a decade. i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari, amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers the 5 MACHINE_ARCH's affected, and all the other arch code touched. it also includes some actual run-time testing of sparc, i386 and shark, and i performed binary comparison upon amiga and x68k as well. some minor details relevant: - move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them down to only the parts ldconfig needs - remove various unused source files - switch amiga bootblocks to using elf2bb.h instead of aout2bb.h
1.29	25-Nov-2009	tron	branches: 1.29.2; 1.29.4; Enable SSP (Stack Smash Protection) in x86 kernels by default (except in i386 *TINY kernels). The NetBSD/i386 "ALL" kernel is unconditionally compiled with SSP enabled. Change approved by the core team.
1.28	11-Dec-2008	alc	branches: 1.28.2; Clean-up makefile stub used to include in the build the binary HAL object
1.27	30-Oct-2008	joerg	branches: 1.27.2; 1.27.8; New assym.h dependency.
1.26	25-Jan-2008	joerg	branches: 1.26.6; 1.26.10; 1.26.16; 1.26.18; 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.
1.25	17-Jan-2008	lukem	Remove unnecessary references to config_time.h.
1.24	11-Jan-2008	bouyer	Merge the bouyer-xeni386 branch to head, at tag bouyer-xeni386-merge1 (the branch is still active and will see i386PAE support developement). Sumary of changes: - switch xeni386 to the x86/x86/pmap.c, and the xen/x86/x86_xpmap.c pmap bootstrap. - merge back most of xen/i386/ to i386/i386 - change the build to reduce diffs between i386 and amd64 in file locations - remove include files that were identical to the i386/amd64 counterparts, the build will find them via the xen-ma/machine link.
1.23	03-Jan-2008	joerg	Add assym.h dependency.
1.22	02-Jan-2008	joerg	Add some missing dependencies on assym.h.
1.21	01-Jan-2008	yamt	add some dependencies on assym.h.
1.20	22-Nov-2007	bouyer	branches: 1.20.6; Pull up the bouyer-xenamd64 branch to HEAD. This brings in amd64 support to NetBSD/Xen, both Dom0 and DomU.
1.19	09-Feb-2007	ad	branches: 1.19.6; 1.19.22; 1.19.24; 1.19.28; 1.19.30; Merge newlock2 to head.
1.18	28-May-2006	pavel	branches: 1.18.6; Give Xen its own linker script, which does not set the physical load address specially. In Xen, the system is already in virtual mode when the kernel is started, so the old behavior of setting physical address to virtual address was actually correct, and the previous change made NetBSD/Xen kernels unbootable. Pointed out, explained and tested by <bouyer>.
1.17	14-May-2006	elad	branches: 1.17.2; integrate kauth.
1.16	04-Apr-2006	gdamore	Convert existing ath users to new Makefile, except for amd64, which needs the rules due to needing to conditionally postprocess the HAL object file. Macppc needs a a non-ELF HAL (EABI) object, so take care of that by default in the atheros include file.
1.15	02-Apr-2006	gdamore	Reorganize ath layout as requested by sam@ and suggested by dyoung@ in http://mail-index.netbsd.org/tech-net/2006/03/15/0000.html. The new layout almost precisely matches FreeBSD, and should make future imports much easier. At the same time, import the current 0.9.16.16 HAL from FreeBSD.

Among others: - move xen/include/amd64/hypercall.h to amd64/include/xen and xen/include/i386/hypercall.h to i386/include/xen - exclude some native files from the build for xenpv - add xen to "machine" config statement for amd64 and i386 - split arch/xen/conf/files.xen to arch/xen/conf/files.xen (for pv drivers) and arch/xen/conf/files.xen.pv (for full pv support) - add GENERIC_XENHVM kernel config which includes GENERIC and add Xen PV drivers.
1.21	11-Mar-2005	bouyer	Move Xen kernel config files to arch/i386, so that they can be added to the i386 release process. Make them include archi/i386/conf/GENERIC.local, like other i386 GENERIC and INSTALL files.

1.17	18-Feb-2005	dsl	Add FFS_NO_SNAPSHOT - commented out in XEN
1.16	31-Jan-2005	hannken	Add file system snapshots to kernel configs. - Ffs internal snapshots get compiled in unconditionally. - File system snapshot device fss(4) added to all kernel configs that have a disk.

1.25	13-Dec-2016	kamil	branches: 1.25.8; Torn down KSTACK_CHECK_DR0, i386-only feature to detect stack overflow This feature was intended to detect stack overflow with CPU Debug Registers (x86). It was never ported to other ports, neither amd64 and should be adapted for SMP... Currently there might be better ways to detect stack overflows like page mapping protection. Since the number of Debug Registers is restricted (4 on x86), torn it down completely. This interface introduced helper functions for Debug Registers, they will be replaced with the new <x86/dbregs.h> interface. KSTACK_CHECK_DR0 was disabled by default and won't affect ordinary users.

1.21	05-Aug-2009	jym	Add Intel SpeedStep and AMD PowerNow! support in Xen dom0. MSR operations are now compiled in by default. Note that MSR support in Xen depends on its version. rdmsr() should always succeed, but wrmsr() to certain registers can end in a NOOP. In that case, the error will be logged (see xm dmesg). Setting CPU frequency (SpeedStep) requires Xen 3.3 with the option cpufreq="dom0-kernel" passed down to hypervisor during boot. Compiled and tested for SpeedStep under i386 for XEN3_DOM0 and XEN3PAE_DOM0 by jym@. amd64 was tested by Joel Carnat. See also http://mail-index.netbsd.org/port-xen/2009/08/02/msg005213.html . Commit requested by bouyer@.
1.20	29-Jul-2009	cegger	remove Xen2 support. ok bouyer@
1.19	19-Feb-2009	jmcneill	vesabios is no more
1.18	23-Jan-2008	bouyer	branches: 1.18.10; 1.18.18; 1.18.20; 1.18.24; 1.18.28; Merge the bouyer-xeni386 branch. This brings in PAE support to NetBSD xeni386 (domU only). PAE support is enabled by 'options PAE', see the new XEN3PAE_DOMU and INSTALL_XEN3PAE_DOMU kernel config files. See the comments in arch/i386/include/{pte.h,pmap.h} to see how it works. In short, we still handle it as a 2-level MMU, with the second level page directory being 4 pages in size. pmap switching is done by switching the L2 pages in the L3 entries, instead of loading %cr3. This is almost required by Xen, which handle the last L2 page (the one mapping 0xc0000000 - 0xffffffff) in a very special way. But this approach should also work for native PAE support if ever supported (in fact, the pmap should almost suport native PAE, what's missing is bootstrap code in locore.S).
1.17	16-Jan-2008	ad	Remove options MATH_EMULATE.
1.16	11-Jan-2008	bouyer	Merge the bouyer-xeni386 branch to head, at tag bouyer-xeni386-merge1 (the branch is still active and will see i386PAE support developement). Sumary of changes: - switch xeni386 to the x86/x86/pmap.c, and the xen/x86/x86_xpmap.c pmap bootstrap. - merge back most of xen/i386/ to i386/i386 - change the build to reduce diffs between i386 and amd64 in file locations - remove include files that were identical to the i386/amd64 counterparts, the build will find them via the xen-ma/machine link.
1.15	22-Nov-2007	bouyer	branches: 1.15.6; Pull up the bouyer-xenamd64 branch to HEAD. This brings in amd64 support to NetBSD/Xen, both Dom0 and DomU.
1.14	05-Jan-2007	jmcneill	branches: 1.14.6; 1.14.22; 1.14.24; 1.14.28; 1.14.30; On the Xbox, prevent scanning past the first device on bus 1.
1.13	01-Oct-2006	bouyer	Map the ISA hole on Xen, which allows us to access the SMBios, which allows us to find the IPMI address. Add IPMI support on Xen (commented out for now)
1.12	28-Sep-2006	bouyer	Add Xen3 support for ACPI and/or MPBIOS + IOAPIC. To help with this, physical CPUs are now configured on mainbus only in dom0, and only to know about their APIC id. virtual CPUs are attached to hypervisor as: vcpu* at hypervisor? and this is what's used as curcpu(). The kernel config files needs to be updated for this, see XEN3_DOM0 or XEN3_DOMU for examples. XEN3_DOM0 now has acpi, MPBIOS and ioapic by default. Note that a Xen dom0 kernel doens't have access to the lapic.
1.11	09-Apr-2006	bouyer	branches: 1.11.8; 1.11.10; Add support for ACPI in xen-3 dom0 support. We can now boot a xen-3 dom0 kernel with a default xen comamnd line.
1.10	15-Jan-2006	bouyer	branches: 1.10.2; 1.10.4; 1.10.6; 1.10.8; 1.10.10; Snapshot of work in progress on NetBSD port to Xen3: - kernel (both dom0 and domU) boot, console is functionnal and it can starts software from a ramdisk - there is no driver front-end expect console for domU yet. - dom0 can probe devices and ex(4) work when Xen3 is booted without acpi and apic support. But the on-board IDE doens't get interrupts. The PCI code still needs work (it's hardcoded to mode 1). Some of this code should be shared with ../x86 The physical insterrupt code needs to get MPBIOS and ACPI support, and do interrupt routing to properly interract with Xen. To enable Xen-3.0 support, add options XEN3 to your kernel config file (this will disable Xen2 support) Changes affecting Xen-2.0 support (no functionnal changes intended): - get more constants from genassym for assembly code - remove some unneeded registers move from start() - map the shared info page from start(), and remove the pte = 0xffffffff hack - vector.S: in hypervisor_callback() make sure %esi points to HYPERVISOR_shared_info before accessing the info page. Remplace some hand-written assembly with the equivalent macro defined in frameasm.h - more debug code, dissabled by default. while here added my copyright on some files I worked on in 2005.

1.6.2.2	07-Apr-2006	tron	Apply patch (requested by bouyer in ticket #1245): Pull up Xen3 domU support. This adds support for the Xen-3 memory bootstrap, xenstore, and block and network device frontend. Xen-3 support is turned on by 'options XEN3', which disable Xen-2 support. Changes affecting non-xen3 specific code: - xbd and xennet at hypervisor now attaches with xbd_hypervisor and xennet_hypervisor - x86_atomic_* renamed to xen_atomic_* - use genassim.cf to pull in more constant from include files for assembly - Map the shared info page from locore.S instead of the 0xffffffff hack in xen_machdep.c - remove some unused code - some __asm__ __volatile__ -> __asm volatile and __inline__ -> inline - more debug code

1.32.10.1	25-Apr-2020	bouyer	Include again xen/conf/files.compat for PV kernels, and make it build. My build.sh -u used stale opt_*.h files ...
1.189	17-Oct-2023	bouyer	XENPVH option is not used. Fix consinit.c to use XENPVHVM as intended and XENPVH from defflag
1.188	17-Oct-2023	bouyer	Support non-VGA framebuffers for Xen dom0. This is mandatory for graphic console on EFI-only hardware. Add a xen_genfb_getbtinfo() function which will return a btinfo_framebuffer structure, filled in with parameters provided by Xen when runing as a Xen dom0, call xen_genfb_getbtinfo() instead of lookup_bootinfo(BTINFO_FRAMEBUFFER) when adding properties to the PCI graphic device (when genfb is attached) and in x86_genfb_init() when genfb is used as console. x86/x86/consinit.c: If running as a Xen dom0, use xen_genfb_getbtinfo() to check if we have a genfb console xen/x86/consinit.c: support genfb as possible console xen/x86/consinit.c: use the hypervior IO as console until a better one is found. If the hypervisor is using a serial port for boot messages, we'll get NetBSD's boot message on the serial port too until the real console takes over. xen/x86/autoconf.c: rework device_register() to be closer to the x86 version. Especially make sure that device_pci_register() is called.
1.187	31-Aug-2022	bouyer	branches: 1.187.4; Work in progress on dom0 PVH support: ioctl support for tools. Basically, in PVH mode (where XENFEAT_auto_translated_physmap is enabled), the hypervisor will not map foreing ressources in our virtual address space for us. Instead, we have to pass it an address in our physical address space (but not mapped to some RAM) where the ressource will show up and then enter this PA in pour page table. For this, introduce xenmem_* which manage the PA space. In PVH mode this is just allocated from the iomem_ex extent. With this, I can start a PV domU, and the guest's kernel boots (and the console works). It hangs because the backend driver can't map the frontend ressources (yet). Note that, per https://xenbits.xen.org/docs/unstable/support-matrix.html, dom0 PVH support is still considered experimental by Xen.
1.186	26-May-2020	bouyer	Add need-flags for kernfs. Compile Xen kernfs support only if kernfs is compiled in the kernel. Should fix MODULAR build.
1.185	05-May-2020	bouyer	Make DOM0OPS build for PVH/PVHVM too
1.184	02-May-2020	bouyer	This is called pvh_consinit not hvm_consinit
1.183	02-May-2020	bouyer	Introduce Xen PVH support in GENERIC. This is compiled in with options XENPVHVM x86 changes: - add Xen section and xen pvh entry points to locore.S. Set vm_guest to VM_GUEST_XENPVH in this entry point. Most of the boot procedure (especially page table setup and switch to paged mode) is shared with native. - change some x86_delay() to delay_func(), which points to x86_delay() for native/HVM, and xen_delay() for PVH Xen changes: - remove Xen bits from init_x86_64_ksyms() and init386_ksyms() and move to xen_init_ksyms(), used for both PV and PVH - set ISA no-legacy-devices property for PVH - factor out code from Xen's cpu_bootconf() to xen_bootconf() in xen_machdep.c - set up a specific pvh_consinit() which starts with printk() (which uses a simple hypercall that is available early) and switch to xencons when we can use pmap_kenter_pa().
1.182	25-Apr-2020	bouyer	Merge the bouyer-xenpvh branch, bringing in Xen PV drivers support under HVM guests in GENERIC. Xen support can be disabled at runtime with boot -c disable hypervisor
1.181	21-Apr-2020	msaitoh	Get TSC frequency from CPUID 0x15 and/or x16 for newer Intel processors. - If the max CPUID leaf is >= 0x15, take TSC value from CPUID. Some processors can take TSC/core crystal clock ratio but core crystal clock frequency can't be taken. Intel SDM give us the values for some processors. - It also required to change lapic_per_second to make LAPIC timer correctly. - Add new file x86/x86/identcpu_subr.c to share common subroutines between kernel and userland. Some code in x86/x86/identcpu.c and cpuctl/arch/i386.c will be moved to this file in future. - Add comment to clarify.
1.180	03-Apr-2020	ad	branches: 1.180.2; CPU topology makes almost no sense for Xen, and populates it with B/S values

1.178	14-Feb-2019	cherry	branches: 1.178.4; Welcome XENPVHVM mode. It is UP only, has xbd(4) and xennet(4) as PV drivers. The console is com0 at isa and the native portion is very rudimentary AT architecture, so is probably suboptimal to run without PV support.
1.177	14-Feb-2019	cherry	Snag the final bits of PV only code to conditionally compile under -DXENPV This completes the bifurcation. The next step is to add -DXENPVHVM code.

1.175	25-Dec-2018	mlelstv	Make ipmi driver available to other platforms. Add ACPI attachment.
1.174	25-Dec-2018	cherry	Excise XEN specific code out of x86/x86/intr.c into xen/x86/xen_intr.c While at it, separate the source function tracking so that the interrupt paths are truly independant. Use weak symbol exporting to provision for future PVHVM co-existence of both files, but with independant paths. Introduce assembler code such that in a unified scenario, native interrupts get first priority in spllower(), followed by XEN event callbacks. IPL management and semantics are unchanged - native handlers and xen callbacks are expected to maintain their ipl related semantics. In summary, after this commit, native and XEN now have completely unrelated interrupt handling mechanisms, including intr_establish_xname() and assembler stubs and intr handler management. Happy Christmas!
1.173	24-Dec-2018	cherry	Do not include files for MSI support on XEN dom0. We do not support MSI as of now.
1.172	22-Dec-2018	cherry	This change modifies the mainbus(4) entry point for all x86 sub-archs in the following way: i) It provides a unified entry point in x86/x86/mainbus.c:mainbus_attach() ii) It carves out the preliminary bus attachment sequence that is common to all sub-archs into x86/x86/mainbus.c: x86_cpubus_attach() iii) It consolidates the remaining pathways as internal callee functions so that these may be called piecemeal if required. A special usecase of this is XEN PVHVM which may need to call the native configure path, the xen configure path, or both. iv) It moves the driver private data structures from i386/i386_mainbus.c to an x86/ level one. This allows for other sub-arch's to do similar, if needed. (They do not at the moment). v) For dom0 kernels, it enables 'acpi0 at mainbus?' and 'acpi0 at hypervisorbus'. This serves two purposes: a) To demonstrate the possibility of dynamic configuration tree traversal ordering changes. b) To allow for the common acpi_check(self, "acpibus") call in x86/mainbus.c to not barf when it is called from the dom0 attach path. We allow for the acpi0 device to be a child of mainbus with the changes to amd64/conf/XEN3_DOM0 and i386/conf/XEN3PAE_DOM0 without actually probing further in the code. This path will later be pursued in a PVHVM boot codepath. There should be no operative changes with this change. If there are, please complain loudly.
1.171	22-Dec-2018	cherry	Move mainbus(4) driver files in various x86 sub-archs to name prefixed versions. This allows us to further modularise them by unifying common bus probe code in x86/x86/mainbus.c to be introduced next. This commit has no functional changes. It is done for ease of visibility of newer diffs in the queue.
1.170	26-Jul-2018	maxv	Merge the content of xen_debug.c into xen_machdep.c, there is only one function.
1.169	23-May-2018	maxv	branches: 1.169.2; Merge convert_xmm_s87.c into fpu.c. It contains only two functions, that are used only in fpu.c.
1.168	18-Mar-2018	christos	Separate the compat code in its own file to facilitate module building.
1.167	17-Mar-2018	christos	dedup microcode handling.
1.166	16-Mar-2018	maxv	Remove ipkdb from i386. Also remove unused references in amd64. I already talked about doing that six months ago on port-i386@. Back then it was as general cleanup, but now, with SVS etc, we do actually have good reasons for simplifying the entry points. Ok kamil@. (christos@ was in the conversation too)
1.165	22-Jan-2018	jdolecek	branches: 1.165.2; xen has separate list, update here also for x86/pmap_tlb.c -> x86/x86_tlb.c
1.164	02-Dec-2017	maxv	Drop COMPAT_13 on amd64, already not enabled. Reduces the number of critical places.
1.163	06-Nov-2017	cherry	Summary: xen/x86/intr.c has been retired. Don't try to build it.
1.162	04-Nov-2017	cherry	Remove bitrotted xen specific versions of pci, pciide machdep related code. Use the common x86/ code instead.
1.161	04-Nov-2017	cherry	Retire xen/x86/intr.c and use the new xen specific glue in x86/x86/intr.c The purpose of this change is to expose the x86/include/intr.h API to drivers. Specifically the following functions: void intr_establish_xname(...); void intr_establish(...); void intr_disestablish(...); while maintaining the old API from xen/include/evtchn.h, specifically the following functions: int event_set_handler(...); int event_remove_handler(...); This is so that if things break, we can keep using the old API until everything stabilises. This is a stepping stone towards getting the actual XEN event callback path rework code in place - which can be done opaquely behind the intr.h API - NetBSD/XEN specific drivers that have been ported to the intr.h API should then work without significant further modifications.
1.160	04-Nov-2017	cherry	On XEN dom0, the function xen/x86/intr.c:xen_intr_map() is used to map hardware interrupts to XEN callbacks called 'events'. This function combines both the allocation and the binding. This change is the first part of breaking up that combination into xen_pirq_alloc() and the binding will happen as part of the pic_addroute() callback of a new pseudo PIC_XEN This code will be added later on.
1.159	04-Nov-2017	cherry	On XEN PV, the ISA 8259A PIC is only used on dom0
1.158	04-Nov-2017	cherry	In XEN PV, the idt vector table is not required to be altered at runtime, since only entries for exceptions/traps are registered with the hypervisor and interrupts are managed via a completely different mechanism. This change uses the idt_vec_reserve() mechanism nevertheless, modifying it slightly to only do namespace management in XEN, while on native it will continue to do idt entry init as before. Rationale: Consistent API usage and potential future merging of XEN/non-XEN code. There are no functional changes in this commit.
1.157	04-Nov-2017	cherry	opt_intrdebug.h - this unbreaks the i386 DOMU build under some conditions
1.156	15-Aug-2017	maxv	Merge into x86/.
1.155	15-Aug-2017	maxv	Merge into x86/.
1.154	12-Aug-2017	maxv	Remove vm86. Pass 3.
1.153	09-Aug-2017	maxv	Remove references to compat_ibcs2.
1.152	01-Aug-2017	maxv	Move arch/i386/i386/freebsd_* into compat/freebsd/. COMPAT_FREEBSD is i386-specific.
1.151	01-Aug-2017	maxv	Don't include files.svr4 and files.svr4_32.
1.150	29-Jul-2017	maxv	Drop support for svr4 on i386. This feature is not maintained, not reliable, and of a limited use case. Most svr4 applications got time to be ported to linux, and we do have a functional, maintained linux emulation. Reduces the number of entry points into the kernel, the number of places that need special care (cpu context). Note that compat_svr4 is still available on sparc.
1.149	16-Jul-2017	cherry	branches: 1.149.2; Unify the xen and native x86/ interrupt setup functions and spl traversal data structures. This is towards PVHVM.
1.148	22-Jun-2017	khorben	Register support for SD card readers with Xen DOM0 kernels Tested on a Lenovo ThinkPad T440s (amd64)
1.147	23-May-2017	nonaka	branches: 1.147.2; x86: hypervisor detection from FreeBSD for x2APIC support.
1.146	24-Mar-2017	maxv	Don't compile PMCs on Xen.
1.145	10-Mar-2017	maxv	Move pmc.c into x86/, it can be shared with amd64.
1.144	17-Feb-2017	kre	Copy maxv's files.i386 change to files.xen ... this might fix the i386 xen kernel builds (I am doing a test build in parallel with this commit, this shouldn't make things worse ... I will make further changes if needed after my build finishes.) Note: I am not currently in a position to test a Xen3 DomU kernel (let alone Dom0) so I have no way of knowing whether a Xen kernel with PMC included will actually work correctly or not. If this results in a system that builds, I'd appreciate it if someone who can test the Xen3_DOMU kernel could do so.
1.143	15-Dec-2016	kamil	branches: 1.143.2; Add support for hardware assisted watchpoints/breakpoints API in ptrace(2) Add new ptrace(2) calls: - PT_COUNT_WATCHPOINTS - count the number of available hardware watchpoints - PT_READ_WATCHPOINT - read struct ptrace_watchpoint from the kernel state - PT_WRITE_WATCHPOINT - write new struct ptrace_watchpoint state, this includes enabling and disabling watchpoints The ptrace_watchpoint structure contains MI and MD parts: typedef struct ptrace_watchpoint { int pw_index; /* HW Watchpoint ID (count from 0) / lwpid_t pw_lwpid; / LWP described / struct mdpw pw_md; / MD fields / } ptrace_watchpoint_t; For example amd64 defines MD as follows: struct mdpw { void md_address; int md_condition; int md_length; }; These calls are protected with the __HAVE_PTRACE_WATCHPOINTS guard. Tested on amd64, initial support added for i386 and XEN. Sponsored by <The NetBSD Foundation>
1.142	13-Dec-2016	kamil	Torn down KSTACK_CHECK_DR0, i386-only feature to detect stack overflow This feature was intended to detect stack overflow with CPU Debug Registers (x86). It was never ported to other ports, neither amd64 and should be adapted for SMP... Currently there might be better ways to detect stack overflows like page mapping protection. Since the number of Debug Registers is restricted (4 on x86), torn it down completely. This interface introduced helper functions for Debug Registers, they will be replaced with the new <x86/dbregs.h> interface. KSTACK_CHECK_DR0 was disabled by default and won't affect ordinary users. Sponsored by <The NetBSD Foundation>
1.141	20-May-2016	jnemeth	branches: 1.141.2; make CPU microcode loading dependent on both DOM0OPS AND CPU_UCODE
1.140	27-Feb-2016	mlelstv	no condition for cpu_rng here
1.139	27-Feb-2016	mlelstv	add missing cpu_rng.c to kernel
1.138	11-Nov-2015	skrll	Fix XEN build - does XEN really want/need pmap_pv_track?
1.137	04-Jan-2015	uebayasi	Include files.sljit as i386/amd64 do.
1.136	15-Dec-2014	christos	there is no ibcs2 in amd64 [yet?]
1.135	15-Dec-2014	ozaki-r	Add two new compat files for Xen on amd64
1.134	11-Oct-2014	uebayasi	branches: 1.134.2; Mark machdep files.
1.133	12-Feb-2014	dsl	branches: 1.133.4; 1.133.8; Change i386 to use x86/fpu.c instead of i386/isa/npx.c This changes the trap10 and trap13 code to call directly into fpu.c, removing all the code for T_ARITHTRAP, T_XMM and T_FPUNDA from i386/trap.c Not all of the code thate appeared to handle fpu traps was ever called! Most of the changes just replace the include of machine/npx.h with x86/fpu.h (or remove it entirely).
1.132	11-Feb-2014	dsl	Move sys/arch/amd64/amd64/fpu.c and sys/arch/amd64/include/fpu.h into sys/arch/x86 in preparation for using the same code for i386.
1.131	07-Feb-2014	dsl	Convert the amd64 build to use x86/cpu_extended_state.h so that the fpu definitions match those of i386. Mostly just structure and field renames, in addition: 1) process_xmm_to_s87() and process_s87_to_xmm() moved into x86/convert_xmm_s87.c so they can be used by amd64's netbsd32 code. 2) The linux signal code simplified to use a structure copy for ths fxsave data - it matches the hardware definition and won't change.
1.130	26-Jan-2014	dsl	Remove support for 'external' floating point units and the MS-DOS compatible method of handling floating point exceptions. Make kernel support for teh fpu non-optional (486SX should still work). Only 386 cpus support external fpu, and i386 support was removed years ago. This means that the npx code no longer uses port 0xf0 or interupt 13. All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c is now mandatory for all i386 kernels. I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu() to match the very similar amd64 functions. The fpu of the boot cpu is now initialised by a direct call from cpu_configure(), this enables FP emulation for a 486SX. (for amd64 the cr0 values are set in locore.S and similar). This fixes a long-standing bug in linux_setregs() - which did not save the fpu regsiters if they were active. I've test booted a single cpu i386 kernel (using anita). amd64 builds - none of teh changes should affect it. The i386 XEN kernels build, but I'm not sure where they set cr0, and it might have got lost!
1.129	03-Oct-2012	dsl	branches: 1.129.2; Remove all references to KVM86. It was only ever used by APMBIOS - and then only if an option was selected. Probably didn't work well at all!
1.128	29-Aug-2012	drochner	branches: 1.128.2; Extend the CPU microcode update framework to support Intel x86 CPUs. Contrary to the AMD implementation, it doesn't use xcalls to distribute the update to all CPUs but relies on cpuctl(8) to bind itself to the right CPU -- to keep it simple and avoid possible problems with hyperthreading. Also, it doesn't parse the vendor supplied file to pick the right part for the present CPU model but relies on userland to prepare files with specific filenames. I'll commit a pkg for this in a minute (pkgsrc/sysutils/intel-microcode). The ioctl interface changed; compatibility is provided (should be limited to COMPAT_NETBSD6 as soon as this is available).
1.127	27-Jun-2012	jym	Retire XEN_COMPAT_030001 as detailed on port-xen@: http://mail-index.netbsd.org/port-xen/2012/06/25/msg007431.html The xen_p2m API comes next. ok bouyer@. Tested on i386 PAE and amd64 (Xen 3.3 on private test bed, and Xen 3.4 for Amazon EC2). FWIW, Amazon always reported: hypervisor0 at mainbus0: Xen version 3.4.3-kaos_t1micro multiple times for Europe and US West-1, so I guess they are now at 3.4 (32 and 64 bits).
1.126	07-May-2012	jym	Merge i386 and amd64 version of db_memrw.c. Use this opportunity to skip calculating the VA of the page. Let the CPU deal with the invalidation itself through invlpg + destination address to avoid converting between canonical/non canonical forms.
1.125	14-Jan-2012	pgoyette	No need for CPU_UCODE here now that it is global
1.124	13-Jan-2012	cegger	Support CPU microcode loading via cpuctl(8). Implemented and enabled via CPU_UCODE kernel config option for x86 and Xen Dom0. Tested on different AMD machines with different CPU families. ok wiz@ for the manpages ok releng@ ok core@ via releng@
1.123	22-Sep-2011	jym	branches: 1.123.2; 1.123.6; Expose Xen kernfs entries inside a domU. Patch originally from sborrill@, slightly modified by me to profit from runtime checks for dom0 privileges instead of using compile time macros (DOM0OPS). It should now be possible to use pkgsrc's sysutils/xentools inside a domU to query XenStore entries (or even modify part of it if the domain has enough rights).
1.122	10-Aug-2011	cherry	xen ipi infrastructure
1.121	13-Jun-2011	pgoyette	Include required file for xen acpi
1.120	12-Jun-2011	jruoho	Fix build failure for the odd child, as pointed out by pgoyette@.
1.119	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.
1.118	26-Apr-2011	joerg	branches: 1.118.2; Remove PECOFF/Win32 emulation.
1.117	26-Apr-2011	joerg	Remove Darwin, MACH and Mach-O support.
1.116	18-Apr-2011	jym	Large rewrite of the balloon driver. This one: - turns balloon into a driver that attaches to xenbus(4). This allows to disable the functionality either at compile time or boot time via userconf(4). Driver can implement detach or pmf(9) hooks if deemed necessary. - keeps Cherry's locking model, but simplify it a bit. There is now only one target value serialized inside balloon, we do not feedback alternative value to Xenstore (clients are not expected to see its value evolve behind their back, and can't do much about that either) - implements min threshold; this is an admin-settable value that tells driver to "not balloon below this threshold." This can be used by domain to keep memory reservations, useful if activity is expected in the near future. - in addition to min threshold, the driver implements internally a safeguard value (uvmexp.freemin + 1MiB), so that admin cannot inadvertently set min to a very low value forcing domain into heavy memory pressure and swapping. - create the sysctl(8) kern.xen.balloon tree. 4 nodes are actually present (values are in KiB): - min: (rw) an admin-settable value that prevents ballooning below this mark - max: (ro) the maximum size for reservation, as set by xm(1) mem-max. - current: (ro) the current reservation for domain. - target: (rw) the targetted reservation for domain. - fix a few limitations here and there, most notably the max_reservation hypercall, and KiB vs pages representations at interfaces. The driver is still turned off by default. Enabling it would need more approval, especially from bouyer@, cherry@ and cegger@. FWIW: tested it two days long, from amd64 dom0 (with dom0 ballooning enabled for xend), and bunch of domUs. Did not notice anything suspicious. XXX it still has one big limitation: it cannot hotplug memory pages in uvm(9) if they were not present beforehand. Example: ballooning above physmem will give more pages to domain but it won't use it to serve allocations, unless we teach uvm(9) how to handle the extra pages.
1.115	11-Apr-2011	cegger	build xen kernels again after db_trace merge
1.114	03-Apr-2011	dyoung	Clean up excessive #ifdef'age of NMI trap handling for amd64/i386/xen. Handle NMI in all Xen kernels.

1.112	24-Feb-2011	jruoho	Add cpufeaturebus and est(4) for Xen.
1.111	23-Feb-2011	jruoho	Move ENHANCED_SPEEDSTEP, or henceforth est(4), to the cpufeaturebus.
1.110	02-Dec-2010	bouyer	branches: 1.110.2; 1.110.4; Make maxpartitions 16 on !i386. Fixes hardwiring root on device autoconf index > 0 on amd64. Problem reported and patch tested by Tobias Nygren.
1.109	08-Jul-2010	rmind	Unify i386 and amd64 procfs MD code into x86.
1.108	06-Jul-2010	cherry	The Xen balloon driver enables growing and shrinking PV domains on the fly, by collaborating with UVM and the hypervisor
1.107	10-May-2010	dyoung	Provide pmap_enter_ma(), pmap_extract_ma(), pmap_kenter_ma() in all x86 kernels, and use them in the bus_space(9) implementation instead of ugly Xen #ifdef-age. In a non-Xen kernel, the _ma() functions either call or alias the equivalent _pa() functions. Reviewed on port-xen@netbsd.org and port-i386@netbsd.org. Passes rmind@'s and bouyer@'s inspection. Tested on i386 and on Xen DOMU / DOM0.
1.106	03-Nov-2009	dyoung	branches: 1.106.2; 1.106.4; Add a kernel configuration flag, SPLDEBUG, that activates a per-CPU log of transitions to IPL_HIGH from lower IPLs. SPLDEBUG is only available on i386 and Xen kernels, today. 'options SPLDEBUG' adds instrumentation to spllower() and splraise() as well as routines to start/stop debugging and to record IPL transitions: spldebug_start(), spldebug_stop(), spldebug_raise(), spldebug_lower().
1.105	05-Oct-2009	rmind	Remove X86_IPI_WRITE_MSR (and msr_ipifuncs.c), replace all uses in drivers with xc_broadcast(). AMD K8 PowerNow driver tested by <jakllsch>, thanks! Closes PR/37665.
1.104	16-Aug-2009	manu	Build COMPAT_DARWIN and COMPAT_MACH as a Xen domU too
1.103	05-Aug-2009	jym	Add Intel SpeedStep and AMD PowerNow! support in Xen dom0. MSR operations are now compiled in by default. Note that MSR support in Xen depends on its version. rdmsr() should always succeed, but wrmsr() to certain registers can end in a NOOP. In that case, the error will be logged (see xm dmesg). Setting CPU frequency (SpeedStep) requires Xen 3.3 with the option cpufreq="dom0-kernel" passed down to hypervisor during boot. Compiled and tested for SpeedStep under i386 for XEN3_DOM0 and XEN3PAE_DOM0 by jym@. amd64 was tested by Joel Carnat. See also http://mail-index.netbsd.org/port-xen/2009/08/02/msg005213.html . Commit requested by bouyer@.

1.100	16-Jun-2009	bouyer	Split mc146818-related functions from clock.c into rtc.c. Call rtc_set_ymdhms() from xen/xen/clock.c:xen_rtc_set() for xen3 dom0 kernels as the Xen3 hypervisor doesn't write the new date/time to the CMOS by itself. Now a XEN3_DOM0 kernel properly updates the CMOS time.

1.93	13-Feb-2009	bouyer	Work in progress on PCI front-end/back-end support front-end: - add a xpci* at xenbus? which provides pci busses from the dom0 xpci provides support routines for PCI config space operations and enumeration in xpci_xenbus.c - hypervisor.c: do dom0-style PCI attach only ifdef DOM0OPS - pci_intr_machdep.c: check line value only if DOM0OPS back-end: - add a pciback* at pci? device which takes precedences over all other PCI devices (match return 500) and matches all devices passed to pciback.hide option on boot command line. It exports the PCI device informations to files in /kern/xen/pci/ - hypervisor.c: create /kern/xen earlier so pciback can create its entries while PCI devices are probed - xen_machdep.c: add handling for pciback.hide= frontend is know working on Xen 3.1.x dom0 with ahc(4) and pciide(4) devices. uhci(4) fail when trying to allocate a large contigous DMA buffer. backend is work in progress; support in xentools is not there yet.
1.92	18-Jan-2009	bouyer	branches: 1.92.2; The Xen PCI_BUS_FIXUP/PCI_ADDR_FIXUP has rotted, catch up with x86 changes in this area. Patch provided by FUKAUMI Naoki in PR#40356.
1.91	20-Dec-2008	ad	- Kill NOREDZONE. - Make the redzone conditional on DIAGNOSTIC. - Give amd64 an additional page for the uarea. 2 is not enough.
1.90	20-Nov-2008	ad	Put the COMPAT_NOMID stuff into its own file.
1.89	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
1.88	03-Aug-2008	joerg	branches: 1.88.2; 1.88.4; Move some MD declarations from x86/pci/files.pci to x86/conf/files.x86, so that Xen can use the former. Drop Xen's pcib.c in favor of the x86 code and thereby unbreak ichlpcib.
1.87	11-May-2008	ad	branches: 1.87.4; Update xen for identcpu changes.
1.86	10-May-2008	ad	Make xen build after tsc changes.
1.85	09-May-2008	joerg	Make cpu_idle a macro calling a function pointer on x86. Select the Xen idle routine for Xen, mwait if supported by the CPU and it is not AMD and halt otherwise. As reported by Christoph Egger, AMD Barcelona keeps the CPU in C0 state with MWAIT, contrary to HLT, which uses C1 and therefore much less power.
1.84	25-Apr-2008	ad	branches: 1.84.2; 1.84.4; Include null IPI functions if !MULTIPROCESSOR.
1.83	27-Feb-2008	dogcow	branches: 1.83.2; fix longrun build borkage on i386
1.82	20-Feb-2008	drochner	branches: 1.82.2; 1.82.6; Since files.wscons et al. are included by ~all ports anyway, include them in the mi "files" file, and remove include statements from md files. These shouldn't pull in additional kernel code when not in use, so it shouldn't do any harm except a risk of namespace collisions which should be easy to fix.
1.81	31-Jan-2008	jmmv	Let Xen kernels build with "options MODULAR" enabled by pulling in the appropriate kobj_machdep.c file.
1.80	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.
1.79	16-Jan-2008	ad	Remove options MATH_EMULATE.

1.65	17-Oct-2007	garbled	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.

As a side effect this reduces the size of amd64 GENERIC by about 120kB, and i386 by a smaller amount. Nearly all of the inlines did something slow, or something that does not need to be fast. - Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL. In that case make them inlines. Makes curlwp LKM and preemption safe. - Make bus_space and bus_dma more LKM friendly. - Share a few more files between the ports. - Other minor changes.

1.57	05-Mar-2007	drochner	branches: 1.57.2; 1.57.4; clean up how cpus and ioapics are attached at the mainbus: Seperate "cpubus" and "ioapicbus" -- while they share a common "address space" (the apic id), the kernel doesn't use this fact. There are different data passed to cpus and apics, which caused some ugly polymorphism. This also saves the special "submatch" functions needed to distingush cpus and ioapics for autoconf. (And it makes that "apid" locators wired in the kernel configuration are honored now; this allows one to dumb down an mp box to singleprocessor by userconfig.) Print "apid" locators in the buses "print" function "as everyone does", so the per-port cpu drivers don't need to do it. Being here, constify "struct cpu_functions" and g/c the unused MP_PICMODE flag.

1.51	17-Oct-2006	bouyer	Add ELF_PADDR_OFFSET and VIRT_ENTRY strings to __xen_guest ELF section, so that our kernels works with newer xen-3 hypervisors; and correct the value of VIRT_BASE for dom0. Now that we can embed the values of KERNBASE and KERNTEXTOFF in the binary for Xen, make the domU memory layout the same as dom0 for Xen3 (making it the other way round doens't work; probably because of alignement constraints in the hypervisor). The old domU layout is used if options XEN_COMPAT_030001 is present in the kernel config file. Enable this the domU kernel config files for now, in case someone wants to run a NetBSD domU on an older Xen3 installation.

1.48	28-Sep-2006	bouyer	Add Xen3 support for ACPI and/or MPBIOS + IOAPIC. To help with this, physical CPUs are now configured on mainbus only in dom0, and only to know about their APIC id. virtual CPUs are attached to hypervisor as: vcpu* at hypervisor? and this is what's used as curcpu(). The kernel config files needs to be updated for this, see XEN3_DOM0 or XEN3_DOMU for examples. XEN3_DOM0 now has acpi, MPBIOS and ioapic by default. Note that a Xen dom0 kernel doens't have access to the lapic.
1.47	24-Sep-2006	bouyer	The Xen folks says everyone should use hypercall call page now, make it so. Old hypercall call method still still available with options XEN_NO_HYPERCALLPAGE but this is disabled by default (xen-3.0.2-2 supports hypercall call page just fine).

But the on-board IDE doens't get interrupts. The PCI code still needs work (it's hardcoded to mode 1). Some of this code should be shared with ../x86 The physical insterrupt code needs to get MPBIOS and ACPI support, and do interrupt routing to properly interract with Xen. To enable Xen-3.0 support, add options XEN3 to your kernel config file (this will disable Xen2 support) Changes affecting Xen-2.0 support (no functionnal changes intended): - get more constants from genassym for assembly code - remove some unneeded registers move from start() - map the shared info page from start(), and remove the pte = 0xffffffff hack - vector.S: in hypervisor_callback() make sure %esi points to HYPERVISOR_shared_info before accessing the info page. Remplace some hand-written assembly with the equivalent macro defined in frameasm.h - more debug code, dissabled by default. while here added my copyright on some files I worked on in 2005.

This way, the code in, e.g., lookup_bootinfo, is a bit easier to understand. While here, move the lookup_bootinfo function used in x86 platforms (amd64, i386 and xen) to a common file (x86/x86_machdep.c), as it was exactly the same in all of them.

XXX this means that setups with serial console on com1 will now break with the default kernel. Use userconf(4) (add -c to kernel command line) or change your setup to com0 instead (most bios allows arbitrary mappings of com ports)
1.30	07-Nov-2005	yamt	branches: 1.30.2; some assym cleanup. - move copyin and friends from locore.S to their own file, copy.S. share it between i386 and xen. - defparam KERNBASE and kill KERNBASE_LOCORE hack. - add more symbols to assym.h and use it where appropriate.
1.29	21-Aug-2005	bouyer	Define a xendevbus atttibute and add it to hypervisor. Use it for xen devices which attach to hypervisor. This allows to use config_found_ia() instead of config_found(), instead of relying on the order of which device are written in ioconf.c. From Quentin Garnier.
1.28	20-Aug-2005	bouyer	Deal with the machine address space being non-contigous in bus_dmamem_alloc(): - Define _BUS_AVAIL_END to 0xffffffff, as we don't have an easy way to find the upper bound for our machine address space (and this can change when we swap pages with the hypervisor). - implement _xen_bus_dmamem_alloc_range(), which will request a contigous set of pages to the hypervisor if the pages returned by uvm_pglistalloc() don't fit the constraints. We can't deal with the low/high constraints yet, because Xen doesn't offer a way to get pages in a specific ranges of addresses. Based on patches from Dave Thompson (in private mail), with heavy hacking by me.
1.27	19-Aug-2005	bouyer	Make PCI devices usable for non-domain0 kernels. Based on patches sent by Ceri Storey to port-xen, with some additionnal changes by me: - include bus_dma.c, bus_space.c and pci_machdep.c if pci is defined instead of dom0ops - Make various initialisations, and probe/attach pci busses based on NPCI instead of DOM0OPS - in conf/files.xen, move xen-specific devices before non-xen specific devices so that the xen-specific match function is called first, to avoid false attachement from too liberal match function in non-xen code.

1.13	30-Aug-2004	drochner	Phase out the use of a string as first "attach args" member to control which bustype should be attached with a specific call to config_found() (from a "mainbus" or a bus bridge). Do it for isa/eisa/mca and pci/agp for now. These buses all attach to an mi interface attribute "isabus", "eisabus" etc., and the autoconf framework now allows to specify an interface attribute on config_found() and config_search(), which limits the search of matching config data to these which attach to that specific attribute. So we basically have to call config_found_ia(..., "foobus", ...) where such a bus is attached. As a consequence, where a "mainbus" or alike also attaches other devices (eg CPUs) which do not attach to a specific attribute yet, we need at least pass an attribute name (different from "foobus") so that the foo bus is not found at these places. This made some minor changes necessary which are not obviously related to the mentioned buses.

Changes affecting non-xen3 specific code: - xbd and xennet at hypervisor now attaches with xbd_hypervisor and xennet_hypervisor - x86_atomic_* renamed to xen_atomic_* - use genassim.cf to pull in more constant from include files for assembly - Map the shared info page from locore.S instead of the 0xffffffff hack in xen_machdep.c - remove some unused code - some __asm__ __volatile__ -> __asm volatile and __inline__ -> inline - more debug code
1.18.2.8	29-Mar-2006	tron	Apply patch (requested by bouyer in ticket #1231): Add support for ath at pci for XEN domain0.
1.18.2.7	05-Jan-2006	riz	Pull up following revision(s) (requested by bouyer in ticket #1083): sys/arch/xen/xen/hypervisor.c: revision 1.16 sys/arch/xen/xen/if_xennet.c: revision 1.31 sys/arch/xen/conf/files.xen: revision 1.29 sys/arch/xen/xen/xbd.c: revision 1.22 Define a xendevbus atttibute and add it to hypervisor. Use it for xen devices which attach to hypervisor. This allows to use config_found_ia() instead of config_found(), instead of relying on the order of which device are written in ioconf.c. From Quentin Garnier.
1.18.2.6	25-Aug-2005	tron	Pull up following revision(s) (requested by bouyer in ticket #696): sys/arch/xen/x86/xen_bus_dma.c: revision 1.1 sys/arch/xen/include/bus_private.h: revision 1.2 sys/arch/xen/conf/files.xen: revision 1.28 Deal with the machine address space being non-contigous in bus_dmamem_alloc(): - Define _BUS_AVAIL_END to 0xffffffff, as we don't have an easy way to find the upper bound for our machine address space (and this can change when we swap pages with the hypervisor). - implement _xen_bus_dmamem_alloc_range(), which will request a contigous set of pages to the hypervisor if the pages returned by uvm_pglistalloc() don't fit the constraints. We can't deal with the low/high constraints yet, because Xen doesn't offer a way to get pages in a specific ranges of addresses. Based on patches from Dave Thompson (in private mail), with heavy hacking by me.
1.18.2.5	25-Aug-2005	tron	Pull up following revision(s) (requested by bouyer in ticket #694): sys/arch/xen/xen/hypervisor.c: revision 1.15 sys/arch/xen/xen/evtchn.c: revision 1.16 sys/arch/xen/conf/files.xen: revision 1.27 sys/arch/xen/i386/machdep.c: revision 1.18 Make PCI devices usable for non-domain0 kernels. Based on patches sent by Ceri Storey to port-xen, with some additionnal changes by me: - include bus_dma.c, bus_space.c and pci_machdep.c if pci is defined instead of dom0ops - Make various initialisations, and probe/attach pci busses based on NPCI instead of DOM0OPS - in conf/files.xen, move xen-specific devices before non-xen specific devices so that the xen-specific match function is called first, to avoid false attachement from too liberal match function in non-xen code.
1.18.2.4	18-Aug-2005	tron	Pull up revision 1.26 (requested by yamt in ticket #675): include cardbus/pcmcia. XXX 32bit cards don't work due to the way how xen handles pci configuration space.
1.18.2.3	25-Apr-2005	tron	Pull up revision 1.21 (requested by bouyer in ticket #190): Add sysmon_power attribute to hypervisor, and an handler for CMSG_SHUTDOWN messages. Now a NetBSD guest will reboot or shutdown on 'xm shutdown' commands in domain0.
1.18.2.2	25-Apr-2005	tron	Pull up revision 1.20 (requested by bouyer in ticket #186): Remove xenkbc at hypervisor vga at hypervisor they have been obsoleted by PCI and ISA support, and don't compile any more.
1.18.2.1	21-Apr-2005	tron	Pull up revision 1.19 (requested by yamt in ticket #175): tweak x86 bus_dma code so that it can be used by xen port. - distinguish paddr_t and bus_addr_t. for xen, use bus_addr_t in the sense of machine address. - move _X86_BUS_DMA_PRIVATE part of bus.h into bus_private.h. - remove special handling of xen_shm. we can always grab machine address from pte.

1.64.2.5	19-Nov-2007	bouyer	Get rid of arch/xenamd64, step 1: empty xenamd64/conf - move xenamd64/conf/std.xen to amd64/conf/ - define arch to amd64 amd64/conf/std.xen, and i386 in xen/conf/std.xen (machine is xen) - enclose content of amd64/conf/files.amd64 and i386/conf/files.i386 in ifndef xen/endif, so it can be transparently inclued for xen kernels - support MACHINE_ARCH=x86_64 in xen/conf/Makefile*

1.64.2.1	17-Oct-2007	bouyer	Prepare for xenamd64: - kill xen/i386/identcpu.c, use i386/i386/identcpu.c instead (with a few #ifndef XEN) - move some files that can be shared between i386 and amd64 from xen/i386 to xen/x86 (or to xen/xen for non-cpu-specific code) - split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h - use <xen/...> instead of <machine/...> for cpu-independant include files. more work needed here, i386-specific files should got out of arch/xen to arch/xeni386, and more code shared with arch/i386.

1.180.2.9	25-Apr-2020	bouyer	restore part accidentaly deleted
1.180.2.8	25-Apr-2020	bouyer	sync with bouyer-xenpvh-base2 (HEAD)
1.180.2.7	25-Apr-2020	bouyer	Include again xen/conf/files.compat for PV kernels, and make it build. My build.sh -u used stale opt_*.h files ...
1.180.2.6	20-Apr-2020	bouyer	We need xenbus_bus_dma_tag for PVHVM too, but without phys->machine translation
1.180.2.5	19-Apr-2020	bouyer	Move xen_ipi.c to XENPV only. Make sure we don't need to send events to remote CPUs (outside of IPIs)
1.180.2.4	16-Apr-2020	bouyer	Rename xen/xen/clock.c to xen_clock.c, so that it can be compiled with x86/isa/clock.c call events_default_setup() from hypervisor_match to that event arrays are properly initialised. Use xen_delay() and xen's timecounter for PVHVM.
1.180.2.3	16-Apr-2020	bouyer	Reorganise sources to make it possible to include Xen PVHVM support in native kernels. Among others: - move xen/include/amd64/hypercall.h to amd64/include/xen and xen/include/i386/hypercall.h to i386/include/xen - exclude some native files from the build for xenpv - add xen to "machine" config statement for amd64 and i386 - split arch/xen/conf/files.xen to arch/xen/conf/files.xen (for pv drivers) and arch/xen/conf/files.xen.pv (for full pv support) - add GENERIC_XENHVM kernel config which includes GENERIC and add Xen PV drivers.
1.180.2.2	14-Apr-2020	bouyer	Always patch spllower with cx8_spllower; it works fine for Xen now Include x86/x86/patch.c is !xenpv While there, defopt XENPV
1.180.2.1	11-Apr-2020	bouyer	Move softint and preemtion-related functions out of x86/x86/intr.c to its own file, x86/x86/x86_softintr.c Add x86/x86/x86_softintr.c for native and XenPV Make sure XenPV also check ci_ioending, which is used for softints. Switch XenPV to fast softints and allow kernel preemption. kpreempt_disable() before calling pmap_changeprot_local() run xen_wallclock_time() and xen_global_systime_ns() at splshed() to avoid being interrupted. XXX amd64 lock stubs are racy for XPENDING

Support non-VGA framebuffers for Xen dom0. This is mandatory for graphic console on EFI-only hardware. Add a xen_genfb_getbtinfo() function which will return a btinfo_framebuffer structure, filled in with parameters provided by Xen when runing as a Xen dom0, call xen_genfb_getbtinfo() instead of lookup_bootinfo(BTINFO_FRAMEBUFFER) when adding properties to the PCI graphic device (when genfb is attached) and in x86_genfb_init() when genfb is used as console. x86/x86/consinit.c: If running as a Xen dom0, use xen_genfb_getbtinfo() to check if we have a genfb console xen/x86/consinit.c: support genfb as possible console xen/x86/consinit.c: use the hypervior IO as console until a better one is found. If the hypervisor is using a serial port for boot messages, we'll get NetBSD's boot message on the serial port too until the real console takes over. xen/x86/autoconf.c: rework device_register() to be closer to the x86 version. Especially make sure that device_pci_register() is called. Make sure to always fall back to xen_early_console, even for dom0 Enable genfb in DOM0 kernels Add ext_lfb_base to dom0_vga_console_info, from recent Xen. We know if it's present or not by checking dom0.info_size Add XENPF_get_dom0_console, which gets a dom0_vga_console_info stucture from the hypervisor. To be used by PVH dom0 kernels. XENPVH option is not used. Fix consinit.c to use XENPVHVM as intended and XENPVH from defflag for a dom0 PVH, the dom0_vga_console_info structure has to be retrieved using a platform hypercall; do so in the XENPVHVM case. Now genfb works in a PVH dom0 running on Xen 4.18 (Xen 4.15 doesn't support this platoform op, so no way to make it work here).
1.3	05-May-2020	bouyer	Make DOM0OPS build for PVH/PVHVM too

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.

Among others: - move xen/include/amd64/hypercall.h to amd64/include/xen and xen/include/i386/hypercall.h to i386/include/xen - exclude some native files from the build for xenpv - add xen to "machine" config statement for amd64 and i386 - split arch/xen/conf/files.xen to arch/xen/conf/files.xen (for pv drivers) and arch/xen/conf/files.xen.pv (for full pv support) - add GENERIC_XENHVM kernel config which includes GENERIC and add Xen PV drivers.
1.3	25-Apr-2020	bouyer	Merge the bouyer-xenpvh branch, bringing in Xen PV drivers support under HVM guests in GENERIC. Xen support can be disabled at runtime with boot -c disable hypervisor
1.2	09-Apr-2020	jdolecek	branches: 1.2.2; 1.2.4; update to __XEN_INTERFACE_VERSION__ 0x0003020a aka Xen 3.2.10 this brings grant memory v2 support: - status separated from flags - revoking access needs just memory barrier, no need for expensive cmpxchg16 any more - sub-page hypervisor copy-only grants, to be used by xennet(4) - 64-bit frame, i.e. support for DomU RAM >16TB the grant table is now always allocated on boot to maximum size, it's now never grown in runtime; switch back to regular kmem_alloc()/kmem_free() code now requires v2 support, no compatibility for grant version 1 retained - Xen v2 support predates all currently supported Xen versions also interface for baloon changed slightly, code updated
1.1	09-Apr-2020	jdolecek	move xen/conf/std.xen to i386/conf/std.xen, it's i386-specific split off __XEN_INTERFACE_VERSION__ to new xen/conf/std.xenversion and use from both i386/conf/std.xen and amd64/conf/stf.xen, so that there is single place for the definition
