Hey, I've just committed, to nouveau git, an initial attempt at a replacement for NVIDIA's PGRAPH ucode. It's been tested on NVC0 and NVC4 thus far, but in theory has support for NVC1, NVC3, NVC8 and NVCE also, it'd be good to see how people with these chipsets fare. If you're on NVC1/NVC8/NVCE, current nouveau git will disable acceleration by default anyway, as NVC1 is known broken, and NVC8/NVCE I'm not sure has ever been tested. To force nouveau to attempt acceleration, simply pass "noaccel=0" as an option to the nouveau kernel module. Also, if there's someone out there reading this with a GF119 (NVD9) chipset, I'd love to get a mmiotrace of the NVIDIA binary driver on your card. Nouveau can be configured to use NVIDIA's ucode ("ctxfw=1" module option), I thought it might be useful to switch back and forth to compare stablity/bugs/etc, at least initially. There's likely going to be a number of issues to sort out, so please let me know if you spot any! Thanks! Ben.
