* drm/radeon: reduce sparse false positive warningsMichele Curti2014-10-161-0/+1
| | | | | | | | | | 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..

* drm/radeon/dpm: Reenabling SS on CaymanAlexandre Demers2014-07-101-6/+0
| | | | | | | | | | | | It reverts commit c745fe611ca42295c9d91d8e305d27983e9132ef now that Cayman is stable since VDDCI fix. Spread spectrum was not the culprit. This depends on b0880e87c1fd038b84498944f52e52c3e86ebe59 (drm/radeon/dpm: fix vddci setup typo on cayman).

| * drm/radeon/dpm: move platform caps fetching to a separate functionAlex Deucher2014-02-181-3/+4

|/ | | | | | | | | | | Most laptops seems to have a vblank period of less than 300 and mclk switching works fine. Drop the quirk and set the default threshold to 200. bug: https://bugzilla.kernel.org/show_bug.cgi?id=70701 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* drm/radeon/dpm: use stored max_vddc rather than looking it upAlex Deucher2014-02-061-3/+2

* drm/radeon/dpm: disable mclk switching on desktop RV770Alex Deucher2014-01-201-0/+6
| | | | | | | | | | | | | Mclk switching doesn't seem to work reliably on these cards. Most RV770 boards specify the same mclk for all performance levels anyway so in most cases, this has no affect.

| | | | | | | | | | | This is needed for reporting the max GPU engine clock in OpenCL.

| | | | | | | | | | | | | | | | | | | | | | | | | | Spread spectrum seems to cause hangs when dynamic clock switching is enabled. Disable it for now. This does not affect performance or the amount of power saved.

| | | | | | | | | | | | | | | | | | | | 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.

* drm/radeon/dpm: rework auto performance level enableAlex Deucher2013-09-151-6/+0
| | | | | | | | | | | | | 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.

* drm/radeon/dpm: fix fallback for empty UVD clocksAlex Deucher2013-09-111-3/+7
| | | | | | | | | | | | | Some older 6xx-7xx boards didn't always fill in the UVD clocks properly in the UVD power states. This leads to the driver trying to set a 0 clock which results in slow or broken UVD playback.

* drm/radeonn: gcc fixes for rv7xx/eg/btc dpmAlex Deucher2013-08-301-2/+3
| | | | | | | | | | | | | | 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.

* drm/radeon/dpm: fix spread spectrum setup (v2)Alex Deucher2013-08-071-13/+17
| | | | | | | | | | | | | | | | | | 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>
