Merge tag 'drm-intel-next-2019-02-07' of git://anongit.freedesktop.org/drm/drm-intel into drm-next
UAPI Changes: - Expose RPCS (SSEU) configuration to userspace for Ice Lake in order to allow userspace to reconfigure the subslice config per context basis. (Tvrtko, Lionel) Driver Changes: - Execbuf and preemption improvements including selftests (Chris) - Rename HAS_GMCH_DISPLAY/HAS_GMCH (Rodrigo) - Debugfs error handling fix for robustness (Greg) - Improve reg_rw traces (Ville) - Push clear_intel_crtc_state onto the heap (Chris) - Watermark fixes for Ice Lake (Ville) - Fix enable count array size and bounds checking (Tvrtko) - MST Fixes (Lyude) - Prevent race and handle error on I915_GEM_MMAP (Joonas) - Initial rework for an full atomic gamma mode (Ville) Signed-off-by: Dave Airlie <airlied@redhat.com> From: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190208165000.GA30314@intel.com

* Context SSEU programming
|

*
|

* It may be necessary for either functional or performance reason to configure
|
||||
* a context to run with a reduced number of SSEU (where SSEU stands for Slice/
|
||||
* Sub-slice/EU).
|
||||
*
|
||||
* This is done by configuring SSEU configuration using the below
|
||||
* @struct drm_i915_gem_context_param_sseu for every supported engine which
|
||||
* userspace intends to use.
|
||||
*
|
||||
* Not all GPUs or engines support this functionality in which case an error
|
||||
* code -ENODEV will be returned.
|
||||
*
|
||||
* Also, flexibility of possible SSEU configuration permutations varies between
|
||||
* GPU generations and software imposed limitations. Requesting such a
|
||||
* combination will return an error code of -EINVAL.
|
||||
*
|
||||
* NOTE: When perf/OA is active the context's SSEU configuration is ignored in
|
||||
* favour of a single global setting.
