2022-05-02drm/msm/dpu: Issue MDSS reset during initializationBjorn Andersson
It's typical for the bootloader to bring up the display for showing a boot splash or efi framebuffer. But in some cases the kernel driver ends up only partially configuring (in particular) the DPU, which might result in e.g. that two different data paths attempts to push data to the interface - with resulting graphical artifacts. Naturally the end goal would be to inherit the bootloader's configuration and provide the user with a glitch free handover from the boot configuration to a running DPU. But as implementing seamless transition from the bootloader configuration to the running OS will be a considerable effort, start by simply resetting the entire MDSS to its power-on state, to avoid the partial configuration.

2022-05-02drm/msm/dpu: Bind pingpong block to intf on active ctls in cmd encoderMarijn Suijten
As per the specification of DPU_CTL_ACTIVE_CFG the configuration of active blocks should be proactively specified, and the pingpong block is no different. The downstream display driver [1] confirms this by also calling bind_pingpong_blk on CTL_ACTIVE_CFG. Note that this else-if is always entered, as setup_intf_cfg - unlike this mainline dpu driver that combines both behind the same function pointer - is left NULL in favour of using setup_intf_cfg_v1 when CTL_ACTIVE_CFG is set. This solves continuous timeouts on at least the Qualcomm sm6125 SoC: [drm:dpu_encoder_frame_done_timeout:2091] [dpu error]enc31 frame done timeout [drm:_dpu_encoder_phys_cmd_handle_ppdone_timeout.isra.0] *ERROR* id:31 pp:0 kickoff timeout 0 cnt 1 koff_cnt 1 [drm:dpu_encoder_phys_cmd_prepare_for_kickoff] *ERROR* failed wait_for_idle: id:31 ret:-110 pp:0 In the same way this pingpong block should also be unbound followed by an interface flush when the encoder is disabled, according to the downstream display driver [2].
