2014-01-30drm/radeon: set si_notify_smc_display_change properlyAlex Deucher1-3/+2
This is effectively a revert of 4573388c92ee60b4ed72b8d95b73df861189988c. Forcing a display active when there is none causes problems with dpm on some SI boards which results in improperly initialized dpm state and boot failures on some boards. As for the bug commit 4573388c92ee tried to address, one can manually force the state to high for better performance when using the card as a headless compute node until a better fix is developed. bugs: https://bugs.freedesktop.org/show_bug.cgi?id=73788 https://bugs.freedesktop.org/show_bug.cgi?id=69395 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> cc: stable@vger.kernel.org

Copy/paste typos from the ni code. Should not have any functional change. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-25drm/radeon/pm: move pm handling into the asic specific codeAlex Deucher1-0/+7
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>
2013-12-25drm/radeon/dpm: switch on new late_enable callbackAlex Deucher1-15/+0
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>

git://people.freedesktop.org/~danvet/drm-intel into drm-next Bit a bit -fixes pull request in the merge window than usual dua to two feauture-y things: - Display CRCs are now enabled on all platforms, including the odd DP case on gm45/vlv. Since this is a testing-only feature it should ever hurt, but I figured it'll help with regression-testing -fixes. So I left it in and didn't postpone it to 3.14. - Display power well refactoring from Imre. Would have caused major pain conflict with the bdw stage 1 patches if I'd postpone this to -next. It's only an relatively small interface rework, so shouldn't cause pain. It's also been in my tree since almost 3 weeks already. That accounts for about two thirds of the pull, otherwise just bugfixes: - vlv backlight fix from Jesse/Jani - vlv vblank timestamp fix from Jesse - improved edp detection through vbt from Ville (fixes a vlv issue) - eDP vdd fix from Paulo - fixes for dvo lvds on i830M - a few smaller things all over Note: This contains a backmerge of v3.12. Since the -internal branch always applied on top of -nightly I need that unified base to merge bdw patches. So you'll get a conflict with radeon connector props when pulling this (and nouveau/master will also conflict a bit when Ben doesn't rebase). The backmerge itself only had conflicts in drm/i915. There's also a tiny conflict between Jani's backlight fix and your sysfs lifetime fix in drm-next. * tag 'drm-intel-fixes-2013-11-07' of git://people.freedesktop.org/~danvet/drm-intel: (940 commits) drm/i915/vlv: use per-pipe backlight controls v2 drm/i915: make backlight functions take a connector drm/i915: move opregion asle request handling to a work queue drm/i915/vlv: use PIPE_START_VBLANK interrupts on VLV drm/i915: Make intel_dp_is_edp() less specific drm/i915: Give names to the VBT child device type bits drm/i915/vlv: enable HDA display audio for Valleyview2 drm/i915/dvo: call ->mode_set callback only when the port is running drm/i915: avoid unclaimed registers when capturing the error state drm/i915: Enable DP port CRC for the "auto" source on g4x/vlv drm/i915: scramble reset support for DP port CRC on vlv drm/i915: scramble reset support for DP port CRC on g4x drm/i916: add "auto" pipe CRC source ...

2013-11-01drm/radeon/si: tell dpm there is a display connectedAlex Deucher1-1/+6
On SI asics, the SMC will automatically force the performance level to the lowest level if there are no displays active. This prevents automatic performance scaling on PowerXpress systems or for offscreen rendering or compute when displays are disabled. Going forward, it would be best to dynamically change this, but for now leave scaling enabled.

2013-09-16drm/radeon/dpm: rework auto performance level enableAlex Deucher1-6/+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.

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.

2013-08-08drm/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>
