ICP has two backlight controllers - similar to previous platforms like BXT -, but we only use one controller for now, so we can just reuse the CNP code. v2: Remove the usage of ICP_SECOND_PPS_BACKLIGHT register.(Jani) Reuse CNP code since it is very similar.(Ville) v3 (from Paulo): Rebase. v4 (from Paulo): adjust commit message (James) and comment (Rodrigo).

ICP, like BXT, has has two panel power sequencers. v2: Simplify the code. Remove unwanted register definitions. Make code as close to BXT style as possible. (Ville) Also, remove the use of ICP_SECOND_PPS_BACKLIGHT for now. Moving forward, if we are sure we need to set this register, we can access it. v3: Use INTEL_GEN(dev_priv), make code more readeable. (Ville) v4 (from Paulo): - Coding style fixes. - Add a missing HAS_PCH_CNP -> gen10+ check. - Rebase. v5: Use per platform checks rather than INTEL_GEN(). v4 of this patch breaks on CoffeeLake, since CFL uses CNP and per platform check makes sense in that case. v6 (from Paulo): - v5 was a patch on top of v4, not a new version. Now v6 is correctly a new version of the original patch. Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Reviewed-by: -

Allow sprites to scan out compressed framebuffers. Since different platforms have a different set of planes that support CCS let's add a small helper to determine whether a specific plane supports CCS or not. Currently that information is spread around in many places, and not all the pieces of code even agree with each other. In addition to allowing sprites to scan out compressed fbs, the other fix here is that we stop rejecting them on pipe C on CNL.

4K modes testing by using dummy EDID data has never been working properly on boxes with DP++ (dual-mode) adaptors. The reason for this is that those modes got pruned during hdmi mode validation. intel_hdmi_mode_valid returns CLOCK_HIGH because the pixel clock reported by the 4k mode is higher than dual port TMDS clock limit. However 4k injection does work properly on machines that don't have DP++ adapters because the mode is never validated against the DP++ TMDS clock limit. v2: Don't detect the DP++ limits when we're testing using overridden EDIDs. Make sure to check for the override condition after respecting the value of drm_dp_dual_mode_detect (Jani Nikula).

Watching a light workload on Baytrail (running glxgears and a 1080p decode), instead of the system remaining at low frequency, the glxgears would regularly trigger waitboosting after which it would have to spend a few seconds throttling back down. In this case, the waitboosting is counter productive as the minimal wait for glxgears doesn't prevent it from functioning correctly and delivering frames on time. In this case, glxgears happens to almost always be waiting on the current request, which we already expect to complete quickly (see i915_spin_request) and so avoiding the waitboost on the active request and spinning instead provides the best latency without overcommitting to upclocking. However, if the system falls behind we still force the waitboost. Similarly, we will also trigger upclocking if we detect the system is not delivering frames on time - again using a mechanism that tries to detect a miss and not preemptively upclock. v2: Also skip boosting for after missed vblank if the desired request is already active.

The CDCLK bypass frequency can vary on upcoming platforms, so prepare for that now by tracking its value in the CDCLK state. Currently on BDW+ the bypass frequency is always the reference clock and I didn't bother with earlier platforms since it's not all that clear what's the bypass clock on those. I also didn't bother adding support for changing this frequency, since atm I don't see any need for it. Suggested-by:

Since commit 4e773c3a ("drm/i915: Wire up shrinkctl->nr_scanned"), we track the number of objects we scan and do not wish to exceed that as it will overly penalise our own slabs under mempressure. Given that we now know the target number of objects to scan, use that as our guide for deciding to shrink as opposed to the number of objects we manage to shrink (which doesn't correspond to the numbers we report to shrinkctl).

When testing that the timeout fired, we need to be sure we have waited just long enough for the timeout to have occurred and for the softirq (on another cpu) to have completed. Sleeping for an arbitrary amount is prone to error, so wait for the timeout instead and complain if it was too late. v2: Use wait_event_timeout to provide an upper bound v3: Fix inverted check for wait_event_timeout timing out v4: Restore the check that the fences aren't signalled too early, by inspecting them before the expected timeout.

It's perfectly legal to create a fb with stride < 512, and one of the kms_plane_scaling subtests creates a very small fb. Downgrade the WARN_ON to a simple check check, and because this function is potentially called on every atomic update/pageflip, downgrade the other WARN_ON to a WARN_ON_ONCE, and do the right thing here.

As freeing the objects require serialisation on struct_mutex, we should prefer to use our singlethreaded driver wq that is dedicated to work requiring struct_mutex (hence serialised).The benefit should be less clutter on the system wq, allowing it to make progress even when the driver/struct_mutex is heavily contended.

In order to prevent a race condition where we may end up overaccounting the active state and leaving the busy-stats believing the GPU is 100% busy, lock out the tasklet while we reconstruct the busy state. There is no direct spinlock guard for the execlists->port[], so we need to utilise tasklet_disable() as a synchronous barrier to prevent it, the only writer to execlists->port[], from running at the same time as the enable.

Without an accompanying timer (for internal fences), we can free the fence callback immediately as we do not need to employ the RCU barrier to serialise with the timer. By avoiding the RCU delay, we can avoid the extra mempressure under heavy inter-engine request utilisation. Signed-off-by:
