Link to branch: https://github.com/mediouni-m/qemu whpx (tag for this
submission: whpx-v5)
Missing features:
- PSCI state sync with Hyper-V: notably breaks reboots when multiple cores are
enabled
- Interrupt controller save-restore
- SVE register sync
To do:
- Switching ITS to off by default when using HVF w/ vGIC or WHPX (will probably
do when both the series are merged)
- After that, perhaps exit if ITS is explicitly enabled.
Note:
"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.
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
