On Skylake GT3 we have 2 Video Command Streamers (VCS), which is asymmetrical. For example, HEVC GPU commands can be only dispatched to VCS1 ring. But userspace has no control when using VCS1 or VCS2. This patch introduces a mechanism to avoid the default ping-pong mode and use one specific ring through execution flag. This mechanism is usable for all the platforms with 2 VCS rings. The open source usage is from these two commits in vaapi/intel: commit 702050f04131a44ef8ac16651708ce8a8d98e4b8 Author: Zhao, Yakui <yakui.zhao@intel.com> Date: Mon Nov 17 12:44:19 2014 +0800 Allow the batchbuffer to be submitted with override flag commit a56efcdf27d11ad9b21664b4a2cda72d7f90f5a8 Author: Zhao Yakui <yakui.zhao@intel.com> Date: Mon Nov 17 12:44:22 2014 +0800 Add the override flag to assure that HEVC video command always uses BSD ring0 for SKL GT3 machine v2: fix whitespace (Rodrigo) v3: remove incorrect chunk that came on -collector rebase.

Rather than having "tiled" meaning "is it X-tiled?" convert the field to explicitely store the tiling mode. The code doesn't have to change much as 1 is conveniently I915_TILING_X.

Mika Kuoppala authored
As we now have forcewake domains, take advantage of it by putting the differences in gen fw handling in data rather than in code. In past we have opencoded this quite extensively as the fw handling is in the fast path. There has also been a lot of cargo-culted copy'n'pasting from older gens to newer ones. Now when the releasing of the forcewake is done by deferred timer, it gives chance to consolidate more. Due to the frequency of actual hw access being significantly less. Take advantage of this and generalize the fw handling code as much as possible. But we still aim to keep the forcewake sequence particularities for each gen intact. So the access pattern to fw engines should remain the same. v2: - s/old_ack/clear_ack (Chris) - s/post_read/posting_read (Chris) - less polite commit msg (Chris) v3: - rebase - check and clear wake_count in init v4: - fix posting reads for gen8 (PRTS) Signed-off-by: -

The previous patch changed the config field in intel_crtc to a pointer, but to keep the mechanical changes (done with spatch) separate from the new code, the pointer was made to point to a new _config field with type struct intel_crtc_state added to that struct. This patch improves that code by getting rid of that field, allocating a state struct in intel_crtc_init() a keeping it properly updated when a mode set happens. v2: Manual changes split from previous patch.

Earlier, DRRS structures were specific to eDP (used only in intel_dp). Since DRRS can be extended to other internal display types (if the panel supports multiple RR), modifying structures to be part of drm_i915_private and have a provision to add display related structs like intel_dp. Also, aligning with frontbuffer tracking mechanism, the new structure contains data for busy frontbuffer bits. Signed-off-by:

On VLV/CHV the rc6 residency calculations read a second register to determine the actual units used for the residency value. The variable name 'reg' where that register value is stored shadows the function argument 'reg'. That can easily leave the reader utterly confused, so rename the internal variable to 'clk_reg'.

CherryViewA0_iGfx_BIOS_DRIVER_PUNIT_spec_y14w28d5 tells us not to enable the RP down timeout interrupt, and says that the timeout value is hence not used. We do enable that interrupt currently though, so leaving the timeout as 0 results in very poor performance as the GPU frequency keeps dropping constantly. So just program the register with the recommended value. Leaving the interrupt enabled doesn't seem to do any harm so far. So I've decided to leave it on for now, just to avoid making CHV a special case.
