2024-12-15drm/msm/dpu: filter out too wide modes if no 3dmux is presentAbhinav Kumar
On chipsets such as QCS615, there is no 3dmux present. In such a case, a layer exceeding the max_mixer_width cannot be split, hence cannot be supported. Filter out the modes which exceed the max_mixer_width when there is no 3dmux present. Also, add a check in the dpu_crtc_atomic_check() to return failure for such modes.

Every layer of vop2 should bind a window, and we also need to make sure that this window is not used by other layer. 0x5 is a reserved layer sel value on rk3568, but it will select Cluster3 on rk3588, configure unused layers to 0x5 will lead alpha blending error on rk3588.

2024-12-13i915/guc: Ensure busyness counter increases motonicallyUmesh Nerlige Ramappa
Active busyness of an engine is calculated using gt timestamp and the context switch in time. While capturing the gt timestamp, it's possible that the context switches out. This race could result in an active busyness value that is greater than the actual context runtime value by a small amount. This leads to a negative delta and throws off busyness calculations for the user. If a subsequent count is smaller than the previous one, just return the previous one, since we expect the busyness to catch up.

dp_ctrl_off_link() was created to handle a case where we received a cable connect and then get a cable disconnect without the corresponding dp_display_enable(). For such cases the pixel clock will be off but the link clock will still be on. dp_ctrl_off_link() handles this case by turning off the link clock only. However, the vote removal to the opp table for this case was missed. Remove the opp table vote in dp_ctrl_off_link().
