[PATCH] drm/nouveau: fix crash regression
by Ortwin Glück 01 Oct '12

01 Oct '12

Work around a crash during boot if noaccel is set. NB: still broken in 3.5 as well, used to work in 3.4. Why are people ignoring this? It's a regression!

[Bug 49981] On HD6850, Power Profile doesn't change if 2 screen is attached.

https://bugs.freedesktop.org/show_bug.cgi?id=49981 --- Comment #10 from graham <grhm.perry(a)gmail.com> --- K, using AMD overdrive in windows it seems in single head mode it steps from 100Mhz to 777Mhz and then 900Mhz, but in dual head it idles at 300 Mhz, but switches back to 775Mhz and 900Mhz for mid and high. It doesn't seem to use 600 Mhz (ps3) at all, but it's a fairly safe bet that it's the idle state for triple head, eyefinity stuff. So the order should be; single-head: ps1/cm0, ps1/cm1, ps1/cm2 dual-head: ps2/cm(any), ps1/cm1, ps1/cm2 triple-head: ps3/cm(any), ps1/cm1, ps1/cm2 Thanks for the power states. Need cayman, caicos and turks still. Hopefully they are all the same though. -- You are receiving this mail because: You are the assignee for the bug.
