v3: Fix for GPU/CPU thrashing in DPMS off state
The following patch series is the version 3 of the fix that prevents the application from rendering at uncontrolled rate as explained in this thread: http://lists.x.org/archives/xorg-driver-ati/2012-December/024027.html In this series all attempts to be "smart" and emulate the real CRTC behavior have been thrown away. Instead, when CRTC is disabled we just defer the swaps by a hard-coded constant, with the sole objective to prevent unecessary power dissipation. As I proposed here: http://lists.x.org/archives/xorg-driver-ati/2012-December/024193.html the more "sophisticated" fix will be provided later in a set of follow-on patches. thanks, Ilija ___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati
