Link to branch: https://github.com/mediouni-m/qemu whpx (tag for this 
submission: whpx-v21)

Patches without a review: patches 3, 5, 6, 7

Missing features:
- VM save-restore: interrupt controller state notably
- SVE register sync: I didn't have the time to test this on pre-release 
hardware with SVE2 support yet.
So SVE2 is currently masked for VMs when running this.

Known bugs:
- U-Boot still doesn't work (hangs when trying to parse firmware) but EDK2 does.

Note:

"target/arm/kvm: add constants for new PSCI versions" taken from the mailing 
list.

"accel/system: Introduce hwaccel_enabled() helper" taken from the mailing list, 
added here
as part of this series to make it compilable as a whole.

And another note:

Seems that unlike HVF there isn't direct correspondence between WHv registers 
and the actual register layout,
so didn't do changes there to a sysreg.inc.

Updates for v22:
- Oops, add updated IORT now that the SMMU patches are merged
The revision field in the IORT changed compared to the revision of the SMMU 
patches the artefact was built on.
Ran a make test again in a clean tree to make sure...

in side note: try to make certain that qemu-system-aarch64 is built as part of 
make test on macOS instead of
the unsigned variant only as that might have been why I didn't observe this

Updates for v21:
- Change commit messsage a bit for the ACPI table updates so that it doesn't 
get parsed as a diff
- Split "qtest: hw/arm: virt: add new test case for GICv3 + GICv2m" into two 
commits

Updates for v20:
- Rebase on current origin/staging

Updates for v19:
- Address review comments
- Documentation update
- Base on top of the current target-arm queue 
(https://patchew.org/QEMU/[email protected]/)

Updates for v18:
- MSI-X config patch: remove workaround to keep existing ACPI tables, as even 
Ubuntu has hibernation support
off in their stock kernel...
- Fold patch "whpx: arm64: gicv3: add migration blocker" into "whpx: interrupt 
controller support"
- address review for "whpx: interrupt controller support"

Updates for v17:
- Reworking the MSI-X configuration patches
- Accordingly, its= retains the same behavior as before, so add a test case for 
GICv3 + GICv2m.
- Squashing "whpx: arm64: check for physical address width after WHPX 
availability"
with "whpx: arm64: clamp down IPA size"
- Not worthwhile to have a separate GICv3 + GICv2m patch, squash it into the 
"rework MSI-X
configuration" patch
- Address review comment on "whpx: arm64: gicv3: add migration blocker"

Updates since v16:
- Address some last review comments
- Rebase with the latest origin/staging

Updates since v15:
- Some last tiny changes addressed.

Updates since v14:
- Working around https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87950

It turns out that we can't avoid default: in case with an enum on GCC without 
warnings,
although Clang allows that behavior.

Updates since v13:
- Addressing review comments from Akihiko Odaki
- Squash GICv2 ACPI workaround patch and have it documented as a separate 
function
- Rebase with current origin/staging

Updates since v12:
- Address review comments and make sure that checkpatch shows no errors, make 
test also ran
- Tested the Windows x86_64 build too in addition to Windows arm64 and macOS 
arm64
- Hopefully the last revision, should be ready to merge.

Updates since v11:
- Address review comments
- Rebase up to latest staging
- Switch to assuming Qemu 11.0 as the newest machine model

Updates since v10:
- Bring forward to latest Qemu
- Fix a typo in the GICv3+GICv2m PR

Updates since v9:
- Adding partition reset on the reboot side of things...

Updates since v8:
- v9 and v8 were not submitted properly because of my MTA not behaving, sorry 
for that.
- v10 introduces a new argument, -M msi=, to handle MSI-X configuration more 
granularly.
- That surfaced what I think is a bug (?), with vms->its=1 on GICv2 
configurations... or I did understand everything wrong.
- Oopsie due to email provider ratelimiting.

Updates since v7:
- Oops, fixing bug in "hw/arm: virt: cleanly fail on attempt to use the 
platform vGIC together with ITS".
Other commits are unchanged.

Updates since v6:
- Rebasing
- Fixing a bug in the GICv3+GICv2m case for ACPI table generation
- getting rid of the slots infrastructure for memory management
- Place the docs commit right after the "cleanly fail on attempt to run 
GICv3+GICv2m on an unsupported config" one
as that's what switches ITS to a tristate.
- Fixing a build issue when getting rid of the arch-specific arm64 hvf-stub.

Updates since v5:
- Rebasing
- Address review comments
- Rework ITS enablement to a tristate
- On x86: move away from deprecated APIs to get/set APIC state

Updates since v4:
- Taking into account review comments
- Add migration blocker in the vGICv3 code due to missing interrupt controller 
save/restore
- Debug register sync

Updates since v3:
- Disabling SVE on WHPX
- Taking into account review comments incl:

- fixing x86 support
- reduce the amount of __x86_64__ checks in common code to the minimum 
(winhvemulation)
which can be reduced even further down the road.
- generalize get_physical_address_range into something common between hvf and 
whpx

Updates since v2:
- Fixed up a rebase screwup for whpx-internal.h
- Fixed ID_AA64ISAR1_EL1 and ID_AA64ISAR2_EL1 feature probe for -cpu host
- Switched to ID_AA64PFR1_EL1/ID_AA64DFR0_EL1 instead of their non-AA64 variant

Updates since v1:
- Shutdowns and reboots
- MPIDR_EL1 register sync
- Fixing GICD_TYPER_LPIS value
- IPA size clamping
- -cpu host now implemented
