2014-12-03drm/radeon: enable smc fan control on CIAlex Deucher
This seems to work well on CI boards after fixing the last few bugs noticed by Chernovsky Oleg. On boards with a high default fan speed this should reduce fan noise. Manual fan control is not enabled yet. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2014-11-20drm/radeon/ci: disable needless sclk changesAlex Deucher
The current code always reprogrammed the sclk levels, but we don't currently handle disp sclk requirements so just skip it. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Preferred ordering. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2014-10-16drm/radeon: reduce sparse false positive warningsMichele Curti
include radeon_asic.h header file in the various xxx_dpm.c files to reduce sparse false positive warnings. Not so great patch in itself, but reducing warning count from 391 to 258 may help to see real problems..

2014-08-15drm/radeon: Add missing lines to ci_set_thermal_temperature_rangeOleg Chernovskiy
Properly set the thermal min and max temp on CI. Otherwise, we end up setting the thermal ranges to 0 on resume and end up in the lowest power state. Signed-off-by: Oleg Chernovskiy <algonkvel@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2014-08-05drm/radeon/dpm: handle voltage info fetching on hawaiiAlex Deucher

2014-04-17drm/radeon: disable mclk dpm on R7 260XAlex Deucher

2014-02-18drm/radeon/cik: enable/disable vce cg when encoding v2Alex Deucher
Some of the vce clocks are automatic, others need to be manually enabled. For ease, just disable cg when vce is active. v2: rebased Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2014-02-18drm/radeon/dpm: move platform caps fetching to a separate functionAlex Deucher

2014-01-07drm/radeon/dpm: make some functions static for CIAlex Deucher
Noticed by Rashika Kheria and cherry-picked from her larger patch set. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Rashika Kheria <rashika.kheria@gmail.com>
2013-12-24drm/radeon/pm: move pm handling into the asic specific codeAlex Deucher
We need more control over the ordering of dpm init with respect to the rest of the asic. Specifically, the SMC has to be initialized before the rlc and cg/pg. The pm code currently initializes late in the driver, but we need it to happen much earlier so move pm handling into the asic specific callbacks. This makes dpm more reliable and makes clockgating work properly on CIK parts and should help on SI parts as well. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/dpm: switch on new late_enable callbackAlex Deucher
Right now it's called right after enable, but after reworking the dpm init order, it will get called later to accomodate loading the smc early, but enabling thermal interrupts and block powergating later after the ring tests are complete. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/dpm: add late_enable for CIAlex Deucher
Make sure interrupts are enabled before we enable thermal interrupts. Also, don't powergate uvd until after the ring tests. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/cik: drop cg_update from dpm codeAlex Deucher
I'm not entirely sure this is required and it won't work with the dpm restructing anyway. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2013-09-23drm/radeon/dpm/ci: filter clocks based on voltage/clk dep tablesAlex Deucher
Filter out mclk and sclk levels higher than listed in the clk voltage dependency tables. Supporting these clocks will require additional driver tweaking that isn't supported yet. See bug: https://bugs.freedesktop.org/show_bug.cgi?id=68235 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-09-15drm/radeon/dpm: rework auto performance level enableAlex Deucher
Calling force_performance_level() from set_power_state() doesn't work on some asics because the current power state pointer has not been properly updated at that point. Move the calls to force_performance_level() out of the asic specific set_power_state() functions and into the main power state sequence. Fixes dpm resume on SI.

2013-08-30drm/radeon/dpm: make sure dc performance level limits are valid (CI)Alex Deucher
Check to make sure the dc limits are valid before using them. Some systems may not have a dc limits table. In that case just use the ac limits. This fixes hangs on systems when the power state is changed when on battery (dc) due to invalid performance state parameters.

2013-08-30drm/radeon: gcc fixes for ci dpmAlex Deucher
Newer versions of gcc seem to wander off into the weeds when dealing with variable sizes arrays in structs. Rather than indexing the arrays, use pointer arithmetic.
