2019-05-02drm/i915: Tune down WARN about incorrect VBT TC legacy flagImre Deak1-3/+6
Looks like VBT contains again the wrong information about a port's TypeC legacy vs. DP-alt/TBT-alt type. There is no further issues after we notice this and fix it up, so tune down the WARN to be a a DRM_ERROR. This also avoids CI tainting the kernel and stopping the test run. v2: - Update also code coment accordingly.

We've already committed to enabling audio when intel_audio_codec_enable() is called. We can't back out even if the ELD has turned sour in the meantime. So just spew some debug log and plow ahead. Otherwise the state checker gets unhappy when audio isn't enabled when it is expected to be. I suppose we really ought to precompute the ELD as well, but let's just toss in a FIXME for the future.

2019-05-02drm/i915: Corrupt DSI picture fix for GeminiLakeStanislav Lisovskiy1-0/+9
Currently due to regression CI machine displays show corrupt picture. Problem is when CDCLK is as low as 79200, picture gets unstable, while DSI and DE pll values were confirmed to be correct. Limiting to 158400 as agreed with Ville. We could not come up with any better solution yet, as PLL divider values both for MIPI(DSI PLL) and CDCLK(DE PLL) are correct, however seems that due to some boundary conditions, when clocking is too low we get wrong timings for DSI display. Similar workaround exists for VLV though, so just took similar condition into use. At least that way GLK platform will start to be usable again, with current drm-tip. v2: Fixed commit subject as suggested. v3: Added generic bugs(crc failures, screen not init for GLK DSI which might be affected). v4: Added references tag for bugs affected.

2019-05-01drm/i915: Complete both freed-object passes before draining the workqueueChris Wilson1-3/+3
The workqueue code complains viciously if we try to queue more work onto the queue while attampting to drain it. As we asynchronously free objects and defer their enqueuing with RCU, it is quite tricky to quiesce the system before attempting to drain the workqueue. Yet drain we must to ensure that the worker is idle before unloading the module. Give the freed object drain 3 whole passes with multiple rcu_barrier() to give the defer freeing of several levels each protected by RCU and needing a grace period before its parent can be freed, ultimately resulting in a GEM object being freed after another RCU period. A consequence is that it will make module unload even slower.

2019-04-30drm/i915: Enable pipe HDR mode on ICL if only HDR planes are usedVille Syrjälä3-4/+16
The pipe has a special HDR mode with higher precision when only HDR planes are active. Let's use it. Curiously this fixes the kms_color gamma/degamma tests when using a HDR plane, which is always the case unless one hacks the test to use an SDR plane. If one does hack the test to use an SDR plane it does pass already. I have no actual explanation how the output after the gamma LUT can be different between the two modes. The way the tests are written should mean that the output should be identical between the solid color vs. the gradient. But clearly that somehow doesn't hold true for the HDR planes in non-HDR pipe mode. Anyways, as long as we stick to one type of plane the test should produce sensible results now. v2: s/HDR_MODE/HDR_MODE_PRECISION/ (Shashank) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190412183009.8237-2-ville.syrjala@linux.intel.com Reviewed-by: Uma Shankar <uma.shankar@intel.com> Tested-by: Uma Shankar <uma.shankar@intel.com> Reviewed-by: Shashank Sharma <shashank.sharma@intel.com>

2019-04-26drm/i915: Switch back to an array of logical per-engine HW contextsChris Wilson16-241/+328
We switched to a tree of per-engine HW context to accommodate the introduction of virtual engines. However, we plan to also support multiple instances of the same engine within the GEM context, defeating our use of the engine as a key to looking up the HW context. Just allocate a logical per-engine instance and always use an index into the ctx->engines[]. Later on, this ctx->engines[] may be replaced by a user specified map. v2: Add for_each_gem_engine() helper to iterator within the engines lock v3: intel_context_create_request() helper v4: s/unsigned long/unsigned int/ 4 billion engines is quite enough. v5: Push iterator locking to caller Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190426163336.15906-7-chris@chris-wilson.co.uk

2019-04-26drm/i915/gvt: Pin the per-engine GVT shadow contextsChris Wilson4-76/+73
Our eventual goal is to rid request construction of struct_mutex, with the short term step of lifting the struct_mutex requirements into the higher levels (i.e. the caller must ensure that the context is already pinned into the GTT). In this patch, we pin GVT's shadow context upon allocation and so keep them pinned into the GGTT for as long as the virtual machine is alive, and so we can use the simpler request construction path safe in the knowledge that the hard work is already done.
