drm/msm/dpu: modify encoder programming for CDM over DP Adjust the encoder format programming in the case of video mode for DP to accommodate CDM related changes. Changes in v4: - Remove hw_cdm check in dpu_encoder_needs_periph_flush() - Remove hw_cdm check when getting the fmt_fourcc in dpu_encoder_phys_vid_enable() Changes in v2: - Move timing engine programming to a separate patch from this one - Move update_pending_flush_periph() invocation completely to this patch - Change the logic of dpu_encoder_get_drm_fmt() so that it only calls drm_mode_is_420_only() instead of doing additional unnecessary checks - Create new functions msm_dp_needs_periph_flush() and it's supporting function dpu_encoder_needs_periph_flush() to check if the mode is YUV420 and VSC SDP is enabled before doing a peripheral flush Signed-off-by: Paloma Arellano <quic_parellan@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/579641/ Link: https://lore.kernel.org/r/20240222194025.25329-17-quic_parellan@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

drm/msm/dpu: pull connector from dpu_encoder_phys to dpu_encoder_virt All physical encoders used by virtual encoder share the same connector, so pull the connector field from dpu_encoder_phys into dpu_encoder_virt structure. Otherwise code suggests that different phys_encs can have different connectors.

drm/msm/disp/dpu1: turn off vblank irqs aggressively in dpu driver Set the flag vblank_disable_immediate = true to turn off vblank irqs immediately as soon as drm_vblank_put is requested so that there are no irqs triggered during idle state. This will reduce cpu wakeups and help in power saving. To enable vblank_disable_immediate flag the underlying KMS driver needs to support high precision vblank timestamping and also a reliable way of providing vblank counter which is incrementing at the leading edge of vblank. This patch also brings in changes to support vblank_disable_immediate requirement in dpu driver. Changes in v1: - Specify reason to add vblank timestamp support. (Rob). - Add changes to provide vblank counter from dpu driver. Changes in v2: - Fix warn stack reported by Rob Clark with v2 patch. Changes in v3: - Move back to HW frame counter (Rob). Changes in v4: - Frame count mismatch was causing a DRM WARN stack spew. DPU HW will increment the frame count at the end of the sync, where as vblank will be triggered at the fetch_start counter which is calculated as v_total - vfp. This is to start fetching early for panels with low vbp w.r.t hw latency lines. Add logic to detect the line count if it falls between vactive and v_total then return incremented frame count value.

drm/msm: Add SDM845 DPU support SDM845 SoC includes the Mobile Display Sub System (MDSS) which is a top level wrapper consisting of Display Processing Unit (DPU) and display peripheral modules such as Display Serial Interface (DSI) and DisplayPort (DP). MDSS functions essentially as a back-end composition engine. It blends video and graphic images stored in the frame buffers and scans out the composed image to a display sink (over DSI/DP). The following diagram represents hardware blocks for a simple pipeline (two planes are present on a given crtc which is connected to a DSI connector): MDSS +---------------------------------+ | +-----------------------------+ | | | DPU | | | | +--------+ +--------+ | | | | | SSPP | | SSPP | | | | | +----+---+ +----+---+ | | | | | | | | | | +----v-----------v---+ | | | | | Layer Mixer (LM) | | | | | +--------------------+ | | | | +--------------------+ | | | | | PingPong (PP) | | | | | +--------------------+ | | | | +--------------------+ | | | | | INTERFACE (VIDEO) | | | | | +---+----------------+ | | | +------|----------------------+ | | | | | +------|---------------------+ | | | | DISPLAY PERIPHERALS | | | | +---v-+ +-----+ | | | | | DSI | | DP | | | | | +-----+ +-----+ | | | +----------------------------+ | +---------------------------------+ The number of DPU sub-blocks (i.e. SSPPs, LMs, PP blocks and INTFs) depends on SoC capabilities. Overview of DPU sub-blocks: --------------------------- * Source Surface Processor (SSPP): Refers to any of hardware pipes like ViG, DMA etc. Only ViG pipes are capable of performing format conversion, scaling and quality improvement for source surfaces. * Layer Mixer (LM): Blend source surfaces together (in requested zorder) * PingPong (PP): This block controls frame done interrupt output, EOL and EOF generation, overflow/underflow control. * Display interface (INTF): Timing generator and interface connecting the display peripherals. DRM components mapping to DPU architecture: ------------------------------------------ PLANEs maps to SSPPs CRTC maps to LMs Encoder maps to PPs, INTFs Data flow setup: --------------- MDSS hardware can support various data flows (e.g.): - Dual pipe: Output from two LMs combined to single display. - Split display: Output from two LMs connected to two separate interfaces. The hardware capabilities determine the number of concurrent data paths possible. Any control path (i.e. pipeline w/i DPU) can be routed to any of the hardware data paths. A given control path can be triggered, flushed and controlled independently. Changes in v3: - Move msm_media_info.h from uapi to dpu/ subdir - Remove preclose callback dpu (it's handled in core) - Fix kbuild warnings with parent_ops - Remove unused functions from dpu_core_irq - Rename mdss_phys to mdss - Rename mdp_phys address space to mdp - Drop _phys from vbif and regdma binding names Signed-off-by: Abhinav Kumar <abhinavk@codeaurora.org> Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Chandan Uddaraju <chandanu@codeaurora.org> Signed-off-by: Jeykumar Sankaran <jsanka@codeaurora.org> Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rajesh Yadav <ryadav@codeaurora.org> Signed-off-by: Sravanthi Kollukuduru <skolluku@codeaurora.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> [robclark minor rebase] Signed-off-by: Rob Clark <robdclark@gmail.com>
