When I where a lad...
This stuff is trivial to reverse engineer. You hook the TVAP or TVALD
under Windows prod the laptop and watch the HCI calls. I have a program
that does it all. The heavy lifting was all done over a decade ago. Then
re-implement using the toshiba/toshiba_apci /dev/toshiba interface or
the equivalent omnibook interface.
There probably should be a generic SMBIOS interface, in Linux, as this
what it all is (the System Management Mode of the processor).
