potential attack surface in virtual environment, if
hot-added CPU need run code with stack or heap before SMI rebase.
Other threats, such as SMRAM or DMA, are same.

in real world, we deprecate AB-seg usage because they are vulnerable to smm
cache poison attack.
I assume cache poison is out of scope in the virtual world, or there is a way
to prevent ABseg cache poison.
thank you!

Hi Paolo
I am not sure what do you mean - "You do not need a reset vector ...".
If so, where is the first instruction of the new CPU in the virtualization
environment?
Please help me understand that at first. Then we can continue the discussion.
Thank you

So I don’t see any problem in OVMF pkg.

Tcg2Config driver is an optional driver, and it can
be customized by platform by design.

.
After BSP returns from SMM_CORE, it will let APs leave loop state, and all CPUs
run RSM instruction to return back.
Hope that helps.
BTW: I am not sure how QEMU emulate SMI. Does SMI can be trigger by 0xB2 port?
And CPU will run to SMBASE in real mode?
Thank you

IA32FamilyCpuBasePkg\PiSmmCommunication - it is CommunicationPeim.
PiSmmCpuDxeSmm works for Quark, but I think it should be easy to port to QEMU
platform.
PiSmmCommunication should be generic, it might be able to put to UefiCpuPkg
later.
Thank you
