[Nouveau] [Bug 71994] Can't set performance level on Fermi card, Linux 3.13
https://bugs.freedesktop.org/show_bug.cgi?id=71994 Ilia Mirkin <imirkin at alum.mit.edu> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |NOTABUG --- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> --- Nope, not supposed to work. Feel free to apply the equivalent of http://cgit.freedesktop.org/~darktama/nouveau/commit/?h=devel-pm&id=ffbf93ba1eb5f05d22bd5419e5f314188801155b to your kernel, and if you want memory reclocking in addition to engine reclocking, you can boot with nouveau.config=NvMemExec=1. However at this point we're not interested in whether it works or not -- it (probably) doesn't on a whole bunch of cards. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=71994 --- Comment #2 from anakin.cs at gmail.com --- Thanks. It doesn't work on my 8800GT either (used to work with the older performance_level setting), I guess this'll solve it as well? -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
