coreboot doesn't compile smihandler.c smmhandler.S, even smm.h file, am I supposed to use other ways to compile SMM mode code?
Hi,
It seems like coreboot doesn't compile smihandler.c, smmhandler.S, even smm.h file. I tried to put some junk into these files, and then make the coreboot source code. it could still build the coreboot.rom image. In other words, coreboot BIOS doesn't use any code under src/cpu/x86/smm/. Since SMM is a special mode, am I supposed to use other ways to compile SMM mode code? Thank you very much!
Best, Fengwei

Well that is really not good! What kind of board are you trying to compile it for?

I am trying to compile it on ASUS M2V-MS SE. My coreboot image works, but
it seem like it doesn't include any SMM code. Am I supposed to use other ways to compile the coreboot(not just do "Make"), then I could compile SMM code into my BIOS?
Thanks, Fengwei

The chipset driver (southbridge mostly) must support it. Your board's southbridge driver doesn't.
One the chipset supports it, SMM code is compiled automatically (see southbridge/intel/i82801gx or mainboard/kontron/986lcd-m)

Ahh, I am pretty sure the smm code was writen for Intel chipsets.... It would be interesting to see it run with both Intel and AMD though....
