Hi Gerd,

 

With below OVMF build and QEMU command, OVMF hangs after SendSmiIpi (mBspApicId) during SmmRelocateBases(), is there any issues with latest code to support SMM on OVMF or my local command/configuration issue?

 

Build (latest edk2 code):

build -p OvmfPkg\OvmfPkgIa32X64.dsc -a IA32 -a X64 -D SECURE_BOOT -D SMM_REQUIRE -D DEBUG_ON_SERIAL_PORT

 

QEMU command (QEMU version: 8.2.0):

qemu-system-x86_64 -machine q35,smm=on -m 4G -net none -drive if=pflash,format=raw,unit=0,file=C:\Dev\Code\edk2\Build\Ovmf3264\DEBUG_VS2019\FV\OVMF_CODE.fd,readonly=on -drive if=pflash,format=raw,unit=1,file=C:\Dev\Code\edk2\Build\Ovmf3264\DEBUG_VS2019\FV\OVMF_VARS.fd -hda fat:rw:hda-contents -serial file:log.log

 

Thanks,

Jiaxin
