It means Nouveau will finally can get good I think.
- salawat 4y agoNope, nouveau is still hosed because they've been blocked ny Nvidia's secrutful FALCON's which have the reclocking and power management API's locked away behind proprietary firmware blobs.
- kaladin-jasnah 4y agoThis new driver targets GPUs with FALCON, and nouveau will be able to control it, as FALCON is GSP (https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-RISC-V-Next-Gen-Falcon https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-R...).
- salawat 4y agoThey're likely changing it because security researchers pwned FALCON. There is a way to leak the hash against which High Security mode FALCON compares the microcode for signature validation. So hopefully you'll forgive me if I maintain my skepticism over this being anything but Nvidia iterating to close a massive security defeat by redesigning their FALCON controller to mitigate the thorough pwning that's been achieved. I don't doubt there are other improvements, I just think the timing is pretty darn convenient, especially for being in the midst of a semiconductor shortage for going and doing a massive manufacturing change like that.
