Source for the ASP firmware is at https://github.com/amd/AMD-ASPFW.

It has a number of gaps, but it is mostly there. It doesn't build, it doesn't have source for some of the service calls iirc (SVC_.*), and the AGESA source isn't open (though a replacement is in progress, openSIL).

This is a ridiculously cool blogpost. Thanks for sharing. Lots of detail.

Since you've looked at the firmware there quite a lot would you be able to share if you noticed if ES/QS CPUs have different configurations in the firmware or if it's just a matter of duplicating and renaming so that they're recognized?

I can't wait for a modern system with an open firmware. Just so that there would be any hope for bugfixes outside "works for (default configuration) Windows".

Good post on troubleshooting the failure to boot, but from the title I was kind of hoping for something like decryption and analysis of the blobs' contents, rather than just metadata. Very "cool" that 3 megabytes of unauditable malware (the public blobs) are still not enough to even boot the platform...
