2013-08-08drm/radeon/dpm: fix spread spectrum setup (v2)Alex Deucher1-13/+1
Need to check for engine and memory clock ss separately and only enable dynamic ss if either of them are found. This should fix systems which have a ss table, but do not have entries for engine or memory. On those systems we may enable dynamic spread spectrum without enabling it on the engine or memory clocks which can lead to a hang in some cases. fixes some systems reported here: https://bugs.freedesktop.org/show_bug.cgi?id=66963 v2: fix typo Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-08drm/radeon/dpm: adjust thermal protection requirementsAlex Deucher1-2/+1
On rv770 and newer, clock gating is not required for thermal protection. The only requirement is that the design utilizes a thermal sensor. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-07-09drm/radeon/dpm: implement vblank_too_short callback for evergreenAlex Deucher1-0/+13
Check if we can switch the mclk during the vblank time otherwise we may get artifacts on the screen when the mclk changes. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
