[edk2-devel] OVMF SMM Support

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

Have not noticed any problems.  I've stopped using OvmfPkgIa32X64.dsc
though and switched to OvmfPkgX64.dsc.  Also running on linux not
windows host, which might make a difference too.

take care,
  Gerd
