	sys/arch/xen/include/xen.h (apply patch)

xen_intr.c: Use kpreempt_disable/enable around access to curcpu().

curcpu() is not otherwise guaranteed to be stable at these points.

While here, nix nonsensical membars.  This need only be synchronized
with interrupts on the same CPU.

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().

Add PVHVM multiprocessor support:
We need the hypervisor to be set up before cpus attaches.
Move hypervisor setup to a new function xen_hvm_init(), called at the
beggining of mainbus_attach(). This function searches the cfdata[] array
to see if the hypervisor device is enabled (so you can disable PV
support with
disable hypervisor
from userconf).
For HVM, ci_cpuid doens't match the virtual CPU index needed by Xen.
Introduce ci_vcpuid to cpu_info. Introduce xen_hvm_init_cpu(), to be
called for each CPU in in its context, which initialize ci_vcpuid and
ci_vcpu, and setup the event callback.
Change Xen code to use ci_vcpuid.

Do not call lapic_calibrate_timer() for VM_GUEST_XENPVHVM, we will use
Xen timers.

Don't call lapic_initclocks() from cpu_hatch(); instead set
x86_cpu_initclock_func to lapic_initclocks() in lapic_calibrate_timer(),
and call *(x86_cpu_initclock_func)() from cpu_hatch().
Also call x86_cpu_initclock_func from cpu_attach() for the boot CPU.
As x86_cpu_initclock_func is called for all CPUs, x86_initclock_func can
be a NOP for lapic timer.

Reorganize Xen code for x86_initclock_func/x86_cpu_initclock_func.
Move x86_cpu_idle_xen() to hypervisor_machdep.c

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

Bump up XEN source API compatibility to 0x00030208 from 0x00030201,

but maintain backwards source API compilation compatibility.

ie; sources with config(5)
options 	__XEN_INTERFACE_VERSION__=0x00030201 # Xen 3.1 interface

should compile and run without problems.

Not that API version 0x00030201 is the lowest version we support now.

Merge jym-xensuspend branch in -current. ok bouyer@.

Goal: save/restore support in NetBSD domUs, for i386, i386 PAE and amd64.

Executive summary:
- split all Xen drivers (xenbus(4), grant tables, xbd(4), xennet(4))
in two parts: suspend and resume, and hook them to pmf(9).
- modify pmap so that Xen hypervisor does not cry out loud in case
it finds "unexpected" recursive memory mappings
- provide a sysctl(7), machdep.xen.suspend, to command suspend from
userland via powerd(8). Note: a suspend can only be handled correctly
when dom0 requested it, so provide a mechanism that will prevent
kernel to blindly validate user's commands

The code is still in experimental state, use at your own risk: restore
can corrupt backend communications rings; this can completely thrash
dom0 as it will loop at a high interrupt level trying to honor
all domU requests.

XXX PAE suspend does not work in amd64 currently, due to (yet again!)
page validation issues with hypervisor. Will fix.

XXX secondary CPUs are not suspended, I will write the handlers
in sync with cherry's Xen MP work.

Tested under i386 and amd64, bear in mind ring corruption though.

No build break expected, GENERICs and XEN* kernels should be fine.
./build.sh distribution still running. In any case: sorry if it does
break for you, contact me directly for reports.

Rename the functions for suspend to reflect that Xen does not hijack
the ACPI "sleepstate" sysctl(7) node anymore.

Add a boolean value to mark that the save/suspend operation has been
notified by dom0, so as to avoid possible errors where admin would like
to schedule the domain for sleep without dom0 being prepared for that. Fail
with EAGAIN in this case.

Sprinkle some KNF.

- Upgrade suspend/resume code to comply with Xen2 removal.
- Add support for PAE domUs suspend/resume.
- Fix an issue regarding initialization of the xbd ring I/O that could end
badly during resume, with invalid block operations submitted to dom0 backend.

NetBSD supports PAE under x86_32 by considering the L2 page as being
4 pages long instead of 1.

Xen validates the page types during resume. Sadly, the hypervisor handles
alternative recursive mappings (== PG/PD entries pointing to pages other
than self) inadequately, which could lead to incorrect page pinning.

As a result, the important change with this patch is to clear these alternative
mappings during suspend, and reset them back to their former self upon
resume. For PAE, approx. all 4 PDIR_SLOT_PTEs could be considered as
alternative recursive mappings.

See comments in pmap.c for further details.

Now, let the testing and bug hunting begin.

Initial code for xen save/restore/migrate facilities.

- split the attach code of frontends in two half: one that is only needed
during autoconf(9) attach/detach phases, and one used at each save/restore
of device state (between suspend and resume).

Applies to hypervisor, xencons, xenbus, xbd, and xennet.

- add a rwlock(9) ("ptom_lock") to protect the different parts in the kernel
 that manipulate MFNs (which could change between a suspend and a resume,
without the kernel noticing it). Parts that require MFNs acquire a reader lock,
while suspend code will acquire a writer lock to ensure that no-other parts
in kernel still use MFNs.

- integrate the suspend code with sysmon.

- various things in pmap(9), and clock.

TODO:
- factorize code a bit more inside frontends drivers.
- remove all alternative recursive (APDP_PDE) mappings found in PD/PT during
suspend, as Xen does not support them.
- abstract the ptom_lock locking, it is only required when kernel preemption
is enabled, or on MP systems.

Current code works mostly. You may experience difficulties in some corner
cases (dom0 warnings about xennet interface errors, and Xen tools failing to
 validate NetBSD's alternative pmaps).

The event bitmasks provided by the hypervisor are unsigned long (so 64bits
on amd64). Make sure to use the right type to store and manipulate them.
This fixes amd64, where basically any event channel > 31 was not working
(and you get there after starting/stopping a domU a few times). Things
would occasionally unwedge though the spllower() callbacks.

- split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h

more work needed here, i386-specific files should got out of arch/xen to
arch/xeni386, and more code shared with arch/i386.

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.

x86 changes for pcc and LKMs.

- Replace most inline assembly with proper functions. 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.

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

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.
