I've built `qemu` from source on macOS 11.3.1 with v8 of the Apple Silicon support patchset[0], as follows:
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" $ brew install ninja pkgconfig glib pixman gnutls libssh libslirp libpng zstd libusb libjpeg $ cd ~/Projects $ git clone https://git.qemu.org/git/qemu.git $ cd qemu $ git checkout master -b wip/hvf $ curl 'https://patchwork.kernel.org/series/485309/mbox/' | git am --3way $ curl 'https://patchew.org/QEMU/ca+pcdy09+oqfxq3ymrnuqe59acoq7py2q4hqowgq4pnepcx...@mail.gmail.com/mbox' | git am --3way $ mkdir build && cd build $ ../configure --target-list=aarch64-softmmu,x86_64-softmmu,i386-softmmu --enable-cocoa $ make -j 8 Then downloaded the latest QEMU EFI, plus OpenBSD 6.9/arm64 installer: $ curl -O 'http://releases.linaro.org/components/kernel/uefi-linaro/latest/release/qemu64/QEMU_EFI.fd' $ curl -O 'https://cdn.openbsd.org/pub/OpenBSD/6.9/arm64/install69.img And attempted to boot qemu, as follows: $ ./qemu-img create -f qcow2 openbsd-arm64.qcow2 10G $ ./qemu-system-aarch64 \ -M virt,highmem=off \ -accel hvf \ -m 512 \ -cpu cortex-a72 \ -bios QEMU_EFI.fd \ -drive file=install69.img,format=raw,id=drive1 \ -drive file=openbsd-arm64.qcow2,if=none,id=drive0,format=qcow2 \ -device virtio-blk-device,drive=drive0 \ -nographic \ -serial tcp::4450,server,telnet,wait $ telnet localhost 4450 disks: sd0* sd1 sd2 sd3 >> OpenBSD/arm64 BOOTAA64 1.4 boot> NOTE: random seed is being reused. booting sd0a:/bsd: 8751984+1790920+569116+830804 [636827+109+1074216+628691]=0xf91440 And qemu crashes with the following error: Assertion failed: (isv), function hvf_vcpu_exec, file ../target/arm/hvf/hvf.c, line 869. I can successfully boot & install if I exclude `-accel hvf`. Not sure if anyone has any thoughts or advice on further debugging this, but it'd be appreciated. I'm just experimenting to try to provide useful bug reports to eventually see OpenBSD booting on Hypervisor.framework on M1 as this is required for virtualizing on macOS 11 Big Sur. Thanks, Morgan
