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 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 Mohamed Mediouni (24): qtest: hw/arm: virt: skip ACPI test for ITS off hw/arm: virt: add GICv2m for the case when ITS is not available tests: data: update AArch64 ACPI tables hw/arm: virt: cleanly fail on attempt to use the platform vGIC together with ITS hw: arm: virt: rework MSI-X configuration docs: arm: update virt machine model description whpx: Move around files before introducing AArch64 support whpx: reshuffle common code whpx: ifdef out winhvemulation on non-x86_64 whpx: common: add WHPX_INTERCEPT_DEBUG_TRAPS define hw, target, accel: whpx: change apic_in_platform to kernel_irqchip whpx: interrupt controller support whpx: add arm64 support whpx: change memory management logic target/arm: cpu: mark WHPX as supporting PSCI 1.3 whpx: arm64: clamp down IPA size hw/arm, accel/hvf, whpx: unify get_physical_address_range between WHPX and HVF whpx: arm64: implement -cpu host target/arm: whpx: instantiate GIC early whpx: arm64: gicv3: add migration blocker whpx: enable arm64 builds whpx: arm64: check for physical address width after WHPX availability whpx: arm64: add partition-wide reset on the reboot path MAINTAINERS: update the list of maintained files for WHPX Philippe Mathieu-Daudé (1): accel/system: Introduce hwaccel_enabled() helper Sebastian Ott (1): target/arm/kvm: add constants for new PSCI versions MAINTAINERS | 6 + accel/hvf/hvf-all.c | 7 +- accel/meson.build | 1 + accel/stubs/whpx-stub.c | 1 + accel/whpx/meson.build | 7 + {target/i386 => accel}/whpx/whpx-accel-ops.c | 6 +- accel/whpx/whpx-common.c | 536 ++++++++++ docs/system/arm/virt.rst | 13 +- hw/arm/virt-acpi-build.c | 27 +- hw/arm/virt.c | 140 ++- hw/i386/x86-cpu.c | 4 +- hw/intc/arm_gicv3_common.c | 3 + hw/intc/arm_gicv3_whpx.c | 248 +++++ hw/intc/meson.build | 1 + include/hw/arm/virt.h | 8 +- include/hw/core/boards.h | 3 +- include/hw/intc/arm_gicv3_common.h | 3 + include/system/hvf_int.h | 4 + include/system/hw_accel.h | 13 + .../whpx => include/system}/whpx-accel-ops.h | 4 +- include/system/whpx-all.h | 20 + include/system/whpx-common.h | 26 + .../whpx => include/system}/whpx-internal.h | 16 +- include/system/whpx.h | 5 +- meson.build | 20 +- target/arm/cpu.c | 3 + target/arm/cpu64.c | 17 +- target/arm/hvf-stub.c | 20 - target/arm/hvf/hvf.c | 6 +- target/arm/hvf_arm.h | 3 - target/arm/kvm-consts.h | 2 + target/arm/meson.build | 2 +- target/arm/whpx/meson.build | 5 + target/arm/whpx/whpx-all.c | 985 ++++++++++++++++++ target/arm/whpx/whpx-stub.c | 15 + target/arm/whpx_arm.h | 17 + target/i386/cpu-apic.c | 2 +- target/i386/hvf/hvf.c | 11 + target/i386/whpx/meson.build | 1 - target/i386/whpx/whpx-all.c | 569 +--------- target/i386/whpx/whpx-apic.c | 2 +- tests/data/acpi/aarch64/virt/APIC.its_off | Bin 164 -> 188 bytes 42 files changed, 2146 insertions(+), 636 deletions(-) create mode 100644 accel/whpx/meson.build rename {target/i386 => accel}/whpx/whpx-accel-ops.c (96%) create mode 100644 accel/whpx/whpx-common.c create mode 100644 hw/intc/arm_gicv3_whpx.c rename {target/i386/whpx => include/system}/whpx-accel-ops.h (92%) create mode 100644 include/system/whpx-all.h create mode 100644 include/system/whpx-common.h rename {target/i386/whpx => include/system}/whpx-internal.h (95%) delete mode 100644 target/arm/hvf-stub.c create mode 100644 target/arm/whpx/meson.build create mode 100644 target/arm/whpx/whpx-all.c create mode 100644 target/arm/whpx/whpx-stub.c create mode 100644 target/arm/whpx_arm.h -- 2.50.1 (Apple Git-155)
