Don't expect any management engine/system management mode instructions any time soon/ever.
- derefr 10y agoNo reason to hide them; presumably, as with firmware updates, you have to load an Intel signing key into a few registers along with your IME/SMM opcode to get it to execute.
- amluto 10y agoHuh? SMM is fully documented at the CPU level. QEMU can even emulate it. Not sure what you mean by "management mode".
- Sephr 10y agoSorry, I meant the undocumented MEI and SMM features.
