2024-10-02drm/i915/hdcp: fix connector refcountingJani Nikula
We acquire a connector reference before scheduling an HDCP prop work, and expect the work function to release the reference. However, if the work was already queued, it won't be queued multiple times, and the reference is not dropped. Release the reference immediately if the work was already queued.

Make sure to call xe_pt_update_ops_fini in xe_pt_update_ops_abort to free any memory the bind allocated. Caught by kmemleak when running Vulkan CTS tests on LNL.

2024-10-02drm/panthor: introduce job cycle and timestamp accountingAdrián Larumbe
Enable calculations of job submission times in clock cycles and wall time. This is done by expanding the boilerplate command stream when running a job to include instructions that compute said times right before and after a user CS. A separate kernel BO is created per queue to store those values. Jobs can access their sampled data through an index different from that of the queue's ringbuffer. The reason for this is saving memory on the profiling information kernel BO, since the amount of simultaneous profiled jobs we can write into the queue's ringbuffer might be much smaller than for regular jobs, as the former take more CSF instructions. This commit is done in preparation for enabling DRM fdinfo support in the Panthor driver, which depends on the numbers calculated herein. A profile mode mask has been added that will in a future commit allow UM to toggle performance metric sampling behaviour, which is disabled by default to save power. When a ringbuffer CS is constructed, timestamp and cycling sampling instructions are added depending on the enabled flags in the profiling mask. A helper was provided that calculates the number of instructions for a given set of enablement mask, and these are passed as the number of credits when initialising a DRM scheduler job.

Existing last step of dsc policy is to restore pbn value under minimum compression when try to greedily disable dsc for a stream failed to fit in MST bw. Optimized dsc params result from optimization step is not necessarily the minimum compression, therefore it is not correct to restore the pbn under minimum compression rate. Restore the pbn under minimum compression instead of the value from optimized pbn could result in the dsc params not correct at the modeset where atomic_check failed due to not enough bw.

2024-10-01drm/amd/display: Configure DTBCLK_P with OPTC only for dcn401Dillon Varone
[WHY] DTBCLK_P is used to generate virtual pixel clock, and to drive the HPO stream encoder clock. Programming the required clock when enabling/disabling both components can cause issues. For example, if HPO is being disabled and clock source is changed to REFCLK, virtual pixel rate will then be wrong, causing issues in CRTC. [HOW] Only program the DTBCLK_P when programming CRTC, as its expected it will be enabled prior to HPO, and disabled after HPO in all valid cases.
