History
Richard Hughes a512d91d43 Report the lockdown status from UEFI and SuperIO plugins 
I was asked the other day how many machines would support a /dev/mem mmap'd
update mechanism, and I had to say that I didn't know. We use direct port IO in
the SuperIO plugin too, and it would be good to know how quickly we need to
port this to something else.

SuperIO

This plugin enumerates the various ITE85* SuperIO embedded controller ICs found in many laptops. Vendors wanting to expose the SuperIO functionality will need to add a HwId quirk entry to superio.quirk.

See https://en.wikipedia.org/wiki/Super_I/O for more details about SuperIO and what the EC actually does.

Other useful links:

GUID Generation

These devices use a custom GUID generated using the SuperIO chipset name:

  • SuperIO-$(chipset), for example SuperIO-IT8512

Vendor ID Security

The vendor ID is set from the baseboard vendor, for example DMI:Star Labs

External interface access

This plugin requires access to raw system memory via inb/outb.
