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

[steeve]

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:

• OpenCore 0.6.0 Debug
• QEMU 4.2.0 + KVM
• WSL2 with Linux 4.19.121-microsoft-standard #1 SMP Fri Jun 19 21:06:10 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
• Ryzen 3950x

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

Interestingly, I can get to the boot menu with:

		-cpu EPYC-v2,kvm=on,vendor=GenuineIntel,vmware-cpuid-freq=on,rdtscp,check,+hypervisor,+svm \

However, these two don't work, and I get the same X64 exception:

		-cpu EPYC-v2,kvm=on,vmware-cpuid-freq=on,rdtscp,check,+hypervisor,+svm \
		-cpu host,kvm=on,vendor=GenuineIntel,vmware-cpuid-freq=on,rdtscp,check,+hypervisor,+svm \

We don't support AMD. Use forums for support.
