Linux 6.5 To Add Support For Some New AMD CCP Hardware

[kiffmet]

Anux could you point me to some tools that let me dissect a bios image for Gigabyte MBs (AMI Firmware)? I'd be willing to dig a bit.

Im not firm with that. I meant standard BIOS/UEFI menu that you can reach with

systemctl reboot --firmware-setup

Anux Ah OK. I know my board's UEFI in and out and I'm certain that the relevant option is not exposed then.

I'm running a 3800X and also receive a message about broken BIOS.
Googling around, there is this section at ccp-dev-v5.c:

/*
* Check for a access to the registers. If this read returns
* 0xffffffff, it's likely that the system is running a broken
* BIOS which disallows access to the device. Stop here and fail
* the initialization (but not the load, as the PSP could get
* properly initialized).
*/
if (qmr == 0xffffffff) {
dev_notice(dev, "ccp: unable to access the device: you might be running a broken BIOS.\n");
return 1;
}

So maybe there is something to do with the motherboard.
