This patch set introduces a new ARM and HVF specific machine type called "vmapple". It mimicks the device model that Apple's proprietary Virtualization.Framework exposes, but implements it in QEMU.
With this new machine type, you can run macOS guests on Apple Silicon systems via HVF. To do so, you need to first install macOS using Virtualization.Framework onto a virtual disk image using a tool like macosvm (https://github.com/s-u/macosvm) $ macosvm --disk disk.img,size=32g --aux aux.img \ --restore UniversalMac_12.0.1_21A559_Restore.ipsw vm.json Then, extract the ECID from the installed VM: $ cat "$DIR/macosvm.json" | python3 -c \ 'import json,sys;obj=json.load(sys.stdin);print(obj["machineId"]) | \ base64 -d | plutil -extract ECID raw - In addition, cut off the first 16kb of the aux.img: $ dd if=aux.img of=aux.img.trimmed bs=$(( 0x4000 )) skip=1 Now, you can just launch QEMU with the bits generated above: $ qemu-system-aarch64 -serial mon:stdio \ -m 4G \ -M vmapple,uuid=6240349656165161789 \ -bios /Sys*/Lib*/Fra*/Virtualization.f*/R*/AVPBooter.vmapple2.bin \ -pflash aux.img.trimmed \ -pflash disk.img \ -drive file=disk.img,if=none,id=root \ -device vmapple-virtio-root,drive=root \ -drive file=aux.img.trimmed,if=none,id=aux \ -device vmapple-virtio-aix,drive=aux \ -accel hvf There are a few limitations with this implementation: - Only runs on macOS because it relies on ParavirtualizesGraphics.Framework - Something is not fully correct on interrupt delivery or similar - the keyboard does not work - No Rosetta in the guest because we lack the private entitlement to enable TSO Over time, I hope that some of the limitations above could cease to exist. This device model would enable very nice use cases with KVM on an Asahi Linux device. Please beware that the vmapple device model only works with macOS 12 guests for now. Newer guests run into Hypervisor.Framework incompatibilities. --- v1 -> v2: - Adapt to system_ss meson.build target - Add documentation - Rework virtio-blk patch to make all vmapple virtio-blk logic subclasses - Add log message on write - Move max slot number to define - Use SPDX header - Remove useless includes Alexander Graf (12): build: Only define OS_OBJECT_USE_OBJC with gcc hw/misc/pvpanic: Add MMIO interface hvf: Increase number of possible memory slots hvf: arm: Ignore writes to CNTP_CTL_EL0 hw: Add vmapple subdir gpex: Allow more than 4 legacy IRQs hw/vmapple/aes: Introduce aes engine hw/vmapple/bdif: Introduce vmapple backdoor interface hw/vmapple/cfg: Introduce vmapple cfg region hw/vmapple/apple-gfx: Introduce ParavirtualizedGraphics.Framework support hw/vmapple/virtio-blk: Add support for apple virtio-blk hw/vmapple/vmapple: Add vmapple machine type MAINTAINERS | 7 + docs/system/arm/vmapple.rst | 68 ++++ docs/system/target-arm.rst | 1 + meson.build | 9 +- hw/vmapple/trace.h | 1 + include/hw/misc/pvpanic.h | 1 + include/hw/pci-host/gpex.h | 7 +- include/hw/pci/pci_ids.h | 1 + include/hw/virtio/virtio-blk.h | 11 +- include/hw/vmapple/bdif.h | 31 ++ include/hw/vmapple/cfg.h | 68 ++++ include/hw/vmapple/virtio-blk.h | 39 ++ include/sysemu/hvf_int.h | 4 +- accel/hvf/hvf-accel-ops.c | 2 +- hw/arm/sbsa-ref.c | 2 +- hw/arm/virt.c | 2 +- hw/block/virtio-blk.c | 18 +- hw/i386/microvm.c | 2 +- hw/loongarch/virt.c | 2 +- hw/mips/loongson3_virt.c | 2 +- hw/misc/pvpanic-mmio.c | 61 +++ hw/openrisc/virt.c | 12 +- hw/pci-host/gpex.c | 36 +- hw/riscv/virt.c | 12 +- hw/vmapple/aes.c | 583 ++++++++++++++++++++++++++++ hw/vmapple/bdif.c | 245 ++++++++++++ hw/vmapple/cfg.c | 105 +++++ hw/vmapple/virtio-blk.c | 212 ++++++++++ hw/vmapple/vmapple.c | 661 ++++++++++++++++++++++++++++++++ hw/xtensa/virt.c | 2 +- target/arm/hvf/hvf.c | 9 + hw/Kconfig | 1 + hw/meson.build | 1 + hw/misc/Kconfig | 4 + hw/misc/meson.build | 1 + hw/vmapple/Kconfig | 33 ++ hw/vmapple/apple-gfx.m | 578 ++++++++++++++++++++++++++++ hw/vmapple/meson.build | 6 + hw/vmapple/trace-events | 47 +++ 39 files changed, 2852 insertions(+), 35 deletions(-) create mode 100644 docs/system/arm/vmapple.rst create mode 100644 hw/vmapple/trace.h create mode 100644 include/hw/vmapple/bdif.h create mode 100644 include/hw/vmapple/cfg.h create mode 100644 include/hw/vmapple/virtio-blk.h create mode 100644 hw/misc/pvpanic-mmio.c create mode 100644 hw/vmapple/aes.c create mode 100644 hw/vmapple/bdif.c create mode 100644 hw/vmapple/cfg.c create mode 100644 hw/vmapple/virtio-blk.c create mode 100644 hw/vmapple/vmapple.c create mode 100644 hw/vmapple/Kconfig create mode 100644 hw/vmapple/apple-gfx.m create mode 100644 hw/vmapple/meson.build create mode 100644 hw/vmapple/trace-events -- 2.39.2 (Apple Git-143) Amazon Development Center Germany GmbH Krausenstr. 38 10117 Berlin Geschaeftsfuehrung: Christian Schlaeger, Jonathan Weiss Eingetragen am Amtsgericht Charlottenburg unter HRB 149173 B Sitz: Berlin Ust-ID: DE 289 237 879
