Link to branch: https://github.com/mediouni-m/qemu whpx (tag for this
submission: whpx-v10)
Missing features:
- PSCI state sync with Hyper-V
- Interrupt controller save-restore: As such, save/restore of VM state is
currently blocked.
- SVE register sync: I didn't have the time to test this on pre-release
hardware with SVE2 support yet.
Known bugs:
- reboots are currently broken
- 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.
"hw/arm: virt: add GICv2m for the case when ITS is not available" present in
both the HVF
vGIC and this series.
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.
And yet another note:
Would it be acceptable to have reboots handled as shutdowns for the initial
merge? Looks to me that due to Qemu changes,
reboots regressed further and don't work even for single-core VMs now...
Updates since v9:
- 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.
Updates since v8:
- 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
