Description
Hi!
I tried to boot OVMF with propolis-standalone,
and got this:
ERRO Unhandled exit @rip:00859f60 InstEmul(InstEmul { inst_data: [243, 108, 235, 10, 227, 8, 236, 136, 7, 72, 255, 199, 226, 248, 76], len: 15 })
thread 'vcpu-0' panicked at bin/propolis-standalone/src/main.rs:729:25:
not yet implemented
After a LOT of debugging, I've traced
the problem to this code:
https://github.com/tianocore/edk2/blob/master/MdePkg/Library/BaseIoLibIntrinsic/X64/IoFifoSev.nasm#L87

Research direction
Read bin/propolis-standalone/src/main.rs around line 729 and trace the InstEmul path for the REP INS sequence reported in the issue. Use the linked EDK2 IoFifoSev.nasm code as the behavior reference. Done means propolis-standalone boots OVMF without the vCPU panic for this instruction.
