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..

2014-02-18drm/radeon/dpm: move platform caps fetching to a separate functionAlex Deucher
It's needed by by both the asic specific functions and the extended table parser. 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>
2013-11-01drm/radeon/dpm: cleanup a type issue with rv6xx_clocks_per_unit()Dan Carpenter
The rv6xx_clocks_per_unit() function pretends it can set flags in a u64 bitfield but really because "1" is an int it doesn't work for more than 32 bits. The only caller truncates the high bits away anyway. I've just changed it to be a u32. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> 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: gcc fixes for rv6xx 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. See bugs: https://bugs.freedesktop.org/show_bug.cgi?id=66932 https://bugs.freedesktop.org/show_bug.cgi?id=66972 https://bugs.freedesktop.org/show_bug.cgi?id=66945 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-07drm/radeon/dpm: disable sclk ss on rv6xxAlex Deucher
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>
2013-08-07drm/radeon/dpm: fix spread spectrum setup (v2)Alex Deucher
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>
2013-07-25drm/radeon/dpm: implement force performance levels for rv6xxAlex Deucher
Allows you to limit the selected power levels via sysfs. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-07-25drm/radeon/dpm: fix displaygap programming on rv6xxAlex Deucher
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>
2013-07-25drm/radeon/dpm: fix a typo in the rv6xx mclk setupAlex Deucher
Need to set high for the last two entries. Looks like a copy and paste typo. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-07-17drm/radeon: add a module parameter to disable aspmAlex Deucher
Can cause hangs when enabled in certain motherboards. Set radeon.aspm=0 to disable aspm. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
