ALPM is a requirement and we don't need to keep it's cached, what were done in commit 97c9de66 ("drm/i915/psr: Fix ALPM cap check for PSR2") but the alpm was not removed from i915_psr. Reviewed-by:

No functional change. But just a minor change to keep up with Spec, since it has changed since commit c3cc39c5 ("drm/i915/icl: program mbus during pipe enable") The instructions previously said to program pipe's B credit = 24 / number of pipes, which is 8 for ICL. Now the spec gives us direct values independent of number of pipes. Let's keep in sync. Also just a reorder on fields to make easier to compare against spec's sequence: A -> BW -> B.

Amber Lake used the same gen graphics as Kaby Lake. Kernel driver should configure KBL's DDI buffer setting for AML ULX as well. So far, driver would load DDI translation table that used for KBL H/S platform and apply it on AML devices. But AML is belong to ULX series. This change will lead driver to apply KBL-Y's DDI table for AML devices to avoid unexpected eDP/DP signal quality issue.

commit 'b9be7853 ("drm/i915/whl: Introducing Whiskey Lake platform")' introduced WHL by moving some of CFL IDs here and using the Spec information of "U43" for most of IDs what appeared to be GT3. However when propagating the change to Mesa, Lionel noticed that based on number of execution unities the classification here seems at least strange. So, let's move for now with the information we trust more: the number of EUs. So we are able to propagate this change across the stack without getting stuck forever.

Sprite enable on ILK-IVB may take two frames to complete when the hardware is in big FIFO mode (LP1+). That is not entirely great as it means the sprite enable may actually happen one frame after we've already signalled flip completion. At the very least crc checks may fail due to the sprite not yet being visible when we expect it. We already have code to deal with big FIFO mode when it comes to the sprite scaling on IVB (WaCxSRDisabledForSpriteScaling:ivb). Let's extend that workaround to kick in whenever the sprite is in the process of being enabled. Also ILK/SNB bspec has some notes to indicate that we should most likely also do the sprite scaling w/a on all three platforms, so let's do that as well. Pretty easy to reproduce on SNB/IVB. ILK has proved more elusive, but let's trust the spec and include it as well. v2: Make sure the pipe is active before the vblank wait Cc: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com> Testcase: igt/kms_plane/pixel-format-pipe-*-planes Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107749Signed-off-by:

When we decide that a plane is attached to the wrong pipe we try to turn off said plane. However we are passing around the crtc we think that the plane is supposed to be using rather than the crtc it is currently using. That doesn't work all that well because we may have to do vblank waits etc. and the other pipe might not even be enabled here. So let's pass the plane's current crtc to intel_plane_disable_noatomic() so that it can its job correctly. To do that semi-cleanly we also have to change the plane readout to record the plane's visibility into the bitmasks of the crtc where the plane is currently enabled rather than to the crtc we want to use for the plane. One caveat here is that our active_planes bitmask will get confused if both planes are enabled on the same pipe. Fortunately we can use plane_mask to reconstruct active_planes sufficiently since plane_mask still has the same meaning (is the plane visible?) during readout. We also have to do the same during the initial plane readout as the second plane could clear the active_planes bit the first plane had already set. v2: Rely on fixup_active_planes() to populate active_planes fully (Daniel) Add Daniel's proposed comment to better document why we do this Drop the redundant intel_set_plane_visible() call Cc: stable@vger.kernel.org # fcba862e8428 drm/i915: Have plane->get_hw_state() return the current pipe Cc: stable@vger.kernel.org Cc: Dennis <dennis.nezic@utoronto.ca> Cc: Daniel Vetter <daniel@ffwll.ch> Tested-by:Dennis <dennis.nezic@utoronto.ca> Tested-by:

Always print out the information whether the port and sink can each do MST. And let's include the modparam in the debug output as well. Makes life a little less confusing when you don't have to wonder why MST isn't kicking in. This does cause a slight change in our behaviour towards the sink. Previously we only read the MSTM_CAP register after passing all the other checks. Now we will read that register regardless. Hopefully some crazy sink doesn't get confused by a simple register read.

Inside the execlists submission tasklet, we often make the mistake of assuming that everything beneath the request is available for use. However, the submission and the request live on two separate timelines, and the request contents may be freed from an early retirement before we have had a chance to run the submission tasklet (think ksoftirqd). To safeguard ourselves against any mistakes, flush the tasklet before we unpin the context if execlists still has a reference to this context. v2: Pull hw_context->active tracking into schedule_in and schedule_out.

Indeed, in case of failure of i915_driver_create(), the load function returns indiscriminately -ENOMEM ignoring the real cause of failure.
