qemu/target/i386/tcg/sysemu/smm_helper.c

/* SMM support */
  #ifdef TARGET_X86_64
  #define SMM_REVISION_ID 0x00020064
  #else
  #define SMM_REVISION_ID 0x00020000
  #endif

So currently, even if qemu command line -cpu parameter is used, those are the possible revision numbers we could see here.

ASEG works with PARALLEL_MP.
