Hello. I'll have some more info soon enough. For now, remember this:

$ flashrom -pinternal:amd_imc_force=yes -w coreboot.rom

Now chances are that will brick your system if you're not already booting coreboot. Expect to do an external flash initially.

GPIO layout

This information should not be considered reliable in any way, shape or form

  • GPIO57 - OUT - seems to control WLAN
  • GPIO54 - OUT - seems to control bluetooth

General Purpose Events layout

  • GPE3 - EC SCI
  • GPE23 - EC SMI

How the EC generates an SCI

  • EC asserts SMI
  • host does blackmagic with SMI, informs EC of servicing SMI
  • EC generates SCI
  • From this point ACPI implementation picks up the SCI and calls the _Qxx methods
