2015-06-03drm/amdkfd: Use DECLARE_BITMAPJoe Perches
Use the generic mechanism to declare a bitmap instead of unsigned long. It seems that "struct kfd_process.allocated_queue_bitmap" is unused. Maybe it could be deleted instead. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

2015-06-01drm/i915: Don't skip request retirement if the active list is emptyVille Syrjälä
Apparently we can have requests even if though the active list is empty, so do the request retirement regardless of whether there's anything on the active list. The way it happened here is that during suspend intel_ring_idle() notices the olr hanging around and then proceeds to get rid of it by adding a request. However since there was nothing on the active lists i915_gem_retire_requests() didn't clean those up, and so the idle work never runs, and we leave the GPU "busy" during suspend resulting in a WARN later.

According to the HSW b-spec we need to try clock divisors of 63 and 72, each 3 or more times, when attempting DP AUX channel communication on a server chipset.

2015-05-28drm/i915: disable IPS while getting the sink CRCsPaulo Zanoni
This commit is the "sink CRC" version of: commit 8c740dcea254a1472df2c0ac5ac585412a2507ec Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Fri Oct 17 18:42:03 2014 -0300 drm/i915: disable IPS while getting the pipe CRCs. For some unknown reason, when IPS gets enabled, the sink CRC changes. Since hsw_enable_ips() doesn't really guarantee to enable IPS (it depends on package C-states), we can't really predict if IPS is enabled or disabled while running our CRC tests, so let's just completely disable IPS while sink CRCs are being used. If we find a way to make IPS not change the pipe CRC result, we may want to fix IPS and then revert this patch (and 8c740dcea too). While this doesn't happen, let's merge this patch, so the IGT tests relying on sink CRCs can work properly. This was discovered while developing a new IGT test, which will probably be called kms_frontbuffer_tracking.

commit 53292cdb066950611e5bc2e0eb109c7edb42af78 ("drm/i915: Workaround to avoid lite restore with HEAD==TAIL") added a check for req0 != null which is unnecessary. The only way req0 could be null is if the list was empty, and this is already addressed at the beginning of execlists_context_unqueue().

2015-05-27drm: Fix off-by-one in vblank hardware counter wraparound handlingMichel Dänzer
dev->max_vblank_count contains the largest value that can be represented by the hardware counter. When the hardware counter wraps around, we have to add that value + 1 to get the same value as if the hardware counter didn't wrap around.

2015-05-27drm/tilcdc: Force building of DRM_TILCDC_SLAVE_COMPATJyri Sarha
If I read Documentation/kbuild/makefiles.txt section 3.6 right, this patch should not be needed. However, without this patch the objects needed for DRM_TILCDC_SLAVE_COMPAT are not linked, if DRM_TILCDC is built as module.

2015-05-27drm/tilcdc: Add DRM_TILCDC_SLAVE_COMPAT for ti,tilcdc,slave binding supportJyri Sarha
Adds a CONFIG_DRM_TILCDC_SLAVE_COMPAT module for "ti,tilcdc,slave" node conversion. The implementation is in tilcdc_slave_compat.c and it uses tilcdc_slave_compat.dts as a basis for creating a DTS overlay. The DTS overlay adds an external tda998x encoder to tilcdc that corresponds to the old tda998x based slave encoder.

2015-05-27drm/tilcdc: use pm_runtime_irq_safe()Tomi Valkeinen
tilcdc calls runtime PM get/put functions everywhere. Some of those places will be called in irq context, crashing the driver. As a quick fix, use pm_runtime_irq_safe() for tilcdc. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Jyri Sarha <jsarha@ti.com>
2015-05-27drm/tilcdc: Add support for external tda998x encoderJyri Sarha
Add support for an external compontised DRM encoder. The external encoder can be connected to tilcdc trough device tree graph binding. The binding document for tilcdc has been updated. The current implementation supports only tda998x encoder. To be able to filter out the unsupported video modes the tilcdc driver needs to hijack the external connectors helper functions. The tilcdc installes new helper functions that are otherwise identical to orignals, but the mode_valid() call-back check the mode first localy, before calling the original call-back. The tilcdc dirver restores the original helper functions before it is unbound from the external device. I got the idea and some lines of code from Jean-Francois Moine's "drm/tilcdc: Change the interface with the tda998x driver"-patch.

2015-05-26drm/i915: Use spinlocks for checking when to waitboostChris Wilson
In commit 1854d5ca0dd7a9fc11243ff220a3e93fce2b4d3e Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Apr 7 16:20:32 2015 +0100 drm/i915: Deminish contribution of wait-boosting from clients we removed an atomic timer based check for allowing waitboosting and moved it below the mutex taken during RPS. However, that mutex can be held for long periods of time on Vallyview/Cherryview as communication with the PCU is slow. As clients may frequently wait for results (e.g. such as tranform feedback) we introduced contention between the client and the RPS worker. We can take advantage of the RPS worker, by switching the wait boost decision to use spin locks and defer the actual reclocking to the worker. Fixes a regression of up to 45% on Baytrail and Baswell! v2 (Daniel): - Use max_freq_softlimit instead of the not-yet-merged boost frequency. - Don't inject a fake irq into the boost work, instead treat client_boost as just another legit waker. v3: Drop the now unused mask (Chris).
