* drm/radeon: use pflip irq on R600+ v2Christian König2014-06-071-0/+6
| | | | | | | | | | | | | | | | | | | | | commit f5d636d2a74b755879feec35e14a259de52ccc07 upstream. Testing the update pending bit directly after issuing an update is nonsense cause depending on the pixel clock the CRTC needs a bit of time to execute the flip even when we are in the VBLANK period. This is just a non invasive patch to solve the problem at hand, a more complete and cleaner solution should follow in the next merge window. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=76564 v2: fix source IDs for CRTC2-6 Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | | | | | | commit 90c4cde9d5a2bb6239cb3e253bb3832ed89dc75c upstream. Don't try and runtime suspend the APU in PX systems. We only want to power down the dGPU. v2: fix harder v3: fix stupid typo v4: consolidate runpm enablement to a single flag bugs: https://bugs.freedesktop.org/show_bug.cgi?id=75127 https://bugzilla.kernel.org/show_bug.cgi?id=72701 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | commit be0949f5eb9c8133a05cf25f108f09e85e79cd32 upstream. There is actually quite a bit of variance based on the asic. v2: fix typo noticed by Jerome.

| | | | | | | | | | The CP semaphore queue on CIK has a bug that triggers if uncompleted waits use the same address while a signal is still pending.

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 ...

On some asics there is no thermal state, so we just use a regular state and force the low performance state. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
