I fumbled the PIPEMISC write into the wrong place. It only gets called for fastsets, but since value needs to be updated based on the set of active planes it needs to be done for all plane updates. Move it to the correct spot. The symptoms include SDR planes never showing up if a previous modeset/fastset left the pipe in HDR mode. This was immediately obvious when running the kms_plane pixel format tests. Unfortunately the test didn't realize it was scanning out pure black all the time and declared success anyway.

Currently we submit the semaphore busywait as soon as the signaler is submitted to HW. However, we may submit the signaler as the tail of a batch of requests, and even not as the first context in the HW list, i.e. the busywait may start spinning far in advance of the signaler even starting. If we wait until the request before the signaler is completed before submitting the busywait, we prevent the busywait from starting too early, if the signaler is not first in submission port. To handle the case where the signaler is at the start of the second (or later) submission port, we will need to delay the execution callback until we know the context is promoted to port0. A challenge for later. Fixes: e8861964 ("drm/i915: Use HW semaphores for inter-engine synchroni sation on gen8+") Signed-off-by:

Given sufficient preemption, we may see a busy system that doesn't advance seqno while performing work across multiple contexts, and given sufficient pathology not even notice a change in ACTHD. What does change between the preempting contexts is their RING, so take note of that and treat a change in the ring address as being an indication of forward progress. Signed-off-by:

Drop the check in GEM parking that the engines were already parked. The intention here was that before we dropped the GT wakeref, we were sure that no more interrupts could be raised -- however, we have already dropped the wakeref by this point and the warning is no longer valid. Signed-off-by:

We are not allowed to rpm_get() inside the runtime-suspend callback, so split the intel_uc_suspend() into the core that assumes the caller holds the wakeref (intel_uc_runtime_suspend), and one that acquires the wakeref as necessary (intel_uc_suspend). Reported-by:

It used to be handy that we only had a couple of headers, but over time i915_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. While at it, rename intel_i2c.c to intel_gmbus.c and the functions to intel_gmbus_*.

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.

Factor out the combo PHY lane power configuration code to a separate helper; it will be also needed by the next patch adding the same configuration for DDI ports. Add support for DDI ports and lane reversal as preparation for the next patch. The PWR_DOWN_LN_1 value is unspecified in the BSpec register description so remove it. v2: - Fix up the wrong assumption that the encodings are the same for DDI and DSI ports. (Jani) v3: - Use intel_ instead of icl_ prefix. (Jani) - Add required headers to intel_combo_phy.h after the upstream header refactoring.

Ville Syrjälä authored
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.

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.

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. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110550Signed-off-by:

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:
