[Nouveau] [Bug 77102] gallium nouveau has no profile in vdpau and libva
https://bugs.freedesktop.org/show_bug.cgi?id=77102 --- Comment #13 from Ilia Mirkin <imirkin at alum.mit.edu> --- Created attachment 97009 --> https://bugs.freedesktop.org/attachment.cgi?id=97009&action=edit firmware present patch OK, upon further code reading, it looks like the way nouveau does class id's is a bit off. That doesn't strictly matter for BSP, but there's a mismatch in the logic between mesa and the kernel, which causes problems for NVD7 and NVD9 cards. In nouveau_vp3_video.c:firmware_present, if (chipset < 0xc0) oclass = 0x85b1; else if (vp5) oclass = 0x95b1; else oclass = 0x90b1; should become if (chipset < 0xc0) oclass = 0x85b1; else if (chipset < 0xe0) oclass = 0x90b1; else oclass = 0x95b1; Since the kernel expects the 90b1 class to be used on the NVD9 card, despite it having VP5. I've attached this change as a patch, please try it out. (If you can't, I'll try to locate someone else with the relevant hardware, but it'd be much easier if you could do it.) -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
