- Add support for ME Soft Temporary Disable Mode. In this mode, ME
doesn't load its kernel and freezes at Bring UP (BUP) phase. This mode
is saved in ME NVRAM (and thus will remain for next reboots and
poweroffs).
- Add support of new CMOS option for Sandy Bridge and Ivy Bridge
ThinkPads.
HOW TO USE
To disable ME:
1. nvramtool -w me_state=Disabled
2. reboot
To enable it back:
1. nvramtool -w me_state=Normal
2. reboot
To check current status:
intelmetool -m
Tested on ThinkPad X230 and ThinkPad X220.
BACKGROUND
There's no Intel documentation that would explain how this should be
implemented, in public. Working binary sequence for MKHI command to put
ME in Soft Temporary Disable Mode, as well as a way to bring ME out of
it (by writing to H_GS register), was found and published by researchers
from PT Security:
1. To disable ME, BIOS issues the disable command (before End of Post)
and reboots. ME is supposed to be disabled on the next boot after
DID (DRAM Init Done).
My numerous tests show that issuing the command and rebooting is not
enough. If we reboot too early, ME will not be disabled. Apparently,
it is doing something in background after receiving the command. It
works with a delay of 500-1000 ms.
I also tried to dump all known (documented) registers, such as GMES
and HFS, before and during the next 2 seconds after execution of the
disable command to find a possible indication that something's
changed in ME and we're ready to reboot. Found nothing
unfortunately.
2. To enable ME back, host writes value 0x20000000 to H_GS.
PT slides don't contain any more information on it, but my tests
show, that after writing this value, GMES[31:28] is changing from
0x01 (BUP phase) to 0x03 (Policy Module) to 0x06 (Host
Communication). Then, after some more time, fw_init_complete bit of
HFS becomes 1.
This means that ME starts loading its kernel immediately, without
reboot.
On the other hand, Lenovo BIOS clearly perform a reboot after
enabling it (one reboot after saving the settings, then ThinkPad
logo appears, and then one more reboot). I'm assuming we have to
reset too.
