I recently mentioned to someone this thread about GPU firmware signing:
And then today I read about Coreboot/Flashrom devs working on directly supporting GPU firmware flashing:
Coreboot’s Flashrom Working On Radeon GPU Flashing Support
Former RadeonHD driver developer Luc Verhaegen is back at the AMD Radeon GPU reverse-engineering game. He’s now pursuing Radeon firmware flashing with the Coreboot Flashrom utility.
Interesing stuff IMHO, so if anyone else comes across this kind of GPU reverse engineering news or something similar please post it here!
