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. 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 (22): 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 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: copy over memory management logic from hvf target/arm: cpu: mark WHPX as supporting PSCI 1.3 hw/arm: virt: cleanly fail on attempt to use the platform vGIC together with ITS docs: arm: update virt machine model description 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 MAINTAINERS: update maintainers for WHPX whpx: apic: use non-deprecated APIs to control interrupt controller state Philippe Mathieu-Daudé (1): accel/system: Introduce hwaccel_enabled() helper Sebastian Ott (1): target/arm/kvm: add constants for new PSCI versions MAINTAINERS | 11 +- accel/hvf/hvf-all.c | 7 +- accel/meson.build | 1 + accel/whpx/meson.build | 7 + {target/i386 => accel}/whpx/whpx-accel-ops.c | 6 +- accel/whpx/whpx-common.c | 666 +++++++++++ docs/system/arm/virt.rst | 10 +- hw/arm/virt-acpi-build.c | 16 +- hw/arm/virt.c | 74 +- hw/i386/x86-cpu.c | 4 +- hw/intc/arm_gicv3_common.c | 3 + hw/intc/arm_gicv3_whpx.c | 249 ++++ hw/intc/meson.build | 1 + include/hw/arm/virt.h | 6 +- include/hw/boards.h | 3 +- include/hw/intc/arm_gicv3_common.h | 3 + include/system/hvf_int.h | 2 + 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 | 23 +- include/system/whpx.h | 4 +- meson.build | 20 +- target/arm/cpu.c | 3 + target/arm/cpu64.c | 19 +- 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 | 1 + target/arm/whpx/meson.build | 5 + target/arm/whpx/whpx-all.c | 1021 +++++++++++++++++ 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 | 48 +- tests/data/acpi/aarch64/virt/APIC.its_off | Bin 164 -> 188 bytes 41 files changed, 2270 insertions(+), 652 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 (89%) 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)
