2013-08-08drm/radeon/dpm: disable sclk ss on rv6xxAlex Deucher1-0/+3
Enabling spread spectrum on the engine clock leads to hangs on some asics. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=66963 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-08drm/radeon/dpm: fix spread spectrum setup (v2)Alex Deucher1-11/+8
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>
2013-07-26drm/radeon/dpm: implement force performance levels for rv6xxAlex Deucher1-0/+35
Allows you to limit the selected power levels via sysfs. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-07-26drm/radeon/dpm: fix displaygap programming on rv6xxAlex Deucher1-2/+2
Need to use the driver state rather than the register state since the displays may not be enabled when the power state is programmed. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
