X64 exception before boot menu with CPU host on Ryzen/QEMU/WSL2 #13

Closed steeve closed 4 years ago

steeve commented 4 years ago

First opened as https://github.com/acidanthera/bugtracker/issues/1105, but was told here might be better.

When using host CPU passthrough with QEMU, I get a X64 exception before the boot menu. When using Penryn, I can get to the boot menu.

Please find the EFI rootfs attached: rootfs.zip

Configuration:

QEMU command line:

qemu-system-x86_64 \
        -cpu host,kvm=on,vmware-cpuid-freq=on,rdtscp,check,+invtsc,+hypervisor \
        -serial stdio \
        "-accel" "kvm" \
        "-machine" "pc-q35-2.11" \
        "-m" 4096 \
        "-smp" "cpus=4" \
        "-usb" \
        "-device" "usb-kbd" \
        "-device" "usb-tablet" \
        -smbios type=2 \
        -drive if=pflash,format=raw,readonly,file=./OVMF/OVMF_CODE.fd \
        -drive if=pflash,format=raw,file=./OVMF/OVMF_VARS.fd \
        "-device" "ide-hd,bus=ide.1,drive=bootloader" \
        "-drive" "id=bootloader,if=none,format=raw,file=./opencore.img"

Note that QEMU complains that Ryzen doesn't support invtsc but adding/removing it doesn't change anything.

Thank you

Fixed, the reason was because of a missing TSC clock source in WSL2's kernel. See https://twitter.com/steeve/status/1297307707779801089?s=20
