The plane's clipped coordinates has already been validated against FB size in the drm_atomic_plane_check(). There is no need to check them again. Remove corresponding checks and inline dpu_plane_validate_src(). Reviewed-by:

Now as all accesses to pipe_cfg and pstate have been cleaned, add struct dpu_hw_sspp_cfg to struct dpu_plane_state, so that dpu_plane_atomic_check() and dpu_plane_atomic_update() do not have a chance to disagree about src/dst rectangles (currently dpu_plane_atomic_check() uses unclipped rectangles, while dpu_plane_atomic_update() uses clipped rectangles calculated by drm_atomic_helper_check_plane_state()).

The helper drm_atomic_helper_check_plane_state() already checks whether the scaled and clipped plane falls into the CRTC visible region (and clears plane_state->visible if it doesn't). Drop the redundant check from dpu_crtc_atomic_check(). Reviewed-by:

The dpu_crtc_atomic_check() compares blending stage with DPU_STAGE_MAX (maximum amount of blending stages supported by the driver), however we should compare it against .max_mixer_blendstages, the maximum blend stage supported by the mixer. Reviewed-by:

Neither source split nor multirect are properly supported at this moment. Both of these checks depend on normalized_zpos being equal for several planes (which is never the case for normalized zpos). Drop these checks to simplify dpu_crtc_atomic_check(). The actual support for either of these features is not removed from the backend code (sspp, ctl, etc). Reviewed-by:

Remove dpu_hw_fmt_layout instance from struct dpu_hw_sspp_cfg, leaving only src_rect and dst_rect. This way all the pipes used by the plane will have a common layout instance (as the framebuffer is shared between them), while still keeping a separate src/dst rectangle configuration for each pipe.

In preparation to adding fully virtualized planes, move struct dpu_hw_sspp instance from struct dpu_plane to struct dpu_plane_state, as it will become a part of state (variable, changes during runtime) rather than part of a plane (ideally should be statically allocated during boot). The sspp pointer is set at the dpu_plane_reset(), since this is the function which allocates the state. Once we have fully virtual plane<->SSPP relationship, the SSPP will be allocated dynamically in the dpu_plane_atomic_check() function. Reviewed-by:

The pipe's layout is not cached, corresponding data structure is zeroed out each time in the dpu_plane_sspp_atomic_update(), right before the call to _dpu_plane_set_scanout() -> dpu_format_populate_layout(). Drop plane_addr comparison against previous layout and corresponding EAGAIN handling. Reviewed-by:

As SSPP blocks are now visible through dpu_kms->rm.sspp_blocks, move SSPP debugfs creation from dpu_plane to dpu_kms. We are going to break the 1:1 correspondence between planes and SSPPs, so it makes no sense anymore to create SSPP debugfs entries in dpu_plane.c Reviewed-by:

For all hardware blocks except SSPP the corresponding struct is named after the block. Rename dpu_hw_pipe (SSPP structure) to dpu_hw_sspp. Also rename struct dpu_hw_pipe_cfg to dpu_hw_sspp_cfg to follow this change. Reviewed-by:

Commit da7716a2 ("drm/msm/dpu: Add support for XR30 format") enabled support for the 10-bit XR30 color format but missed enabling support for the corresponding per-pixel alpha-blending AR30 color format. Declaring only XR30 but not AR30 color format support can trigger bugs in userspace. KDE KWin compositor versions prior to 5.27.3 for example prefer 10-bit color formats, rendering a 1cm^2 black box around the cursor due to missing per-pixel alpha-blending. Signed-off-by:

Currently, DPU will enable TE during prepare_commit(). However, this will cause a crash and reboot to sahara when trying to read/write to register in get_autorefresh_config(), because the core clock rates aren't set at that time. This used to work because phys_enc->hw_pp is only initialized in mode set [1], so the first prepare_commit() will return before any register read/write as hw_pp would be NULL. However, when we try to implement support for INTF TE, we will run into the clock issue described above as hw_intf will *not* be NULL on the first prepare_commit(). This is because the initialization of dpu_enc->hw_intf has been moved to dpu_encoder_setup() [2]. To avoid this issue, let's enable TE during prepare_for_kickoff() instead as the core clock rates are guaranteed to be set then. Depends on: "Implement tearcheck support on INTF block" [3] Changes in V3: - Added function prototypes - Reordered function definitions to make change more legible - Removed prepare_commit() function from dpu_encoder_phys_cmd Changes in V4: - Reworded commit message to be more specific - Removed dpu_encoder_phys_cmd_is_ongoing_pptx() prototype [1] https://gitlab.freedesktop.org/drm/msm/-/blob/msm-next/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c#L1109 [2] https://gitlab.freedesktop.org/drm/msm/-/blob/msm-next/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c#L2339 [3] https://patchwork.freedesktop.org/series/112332/Signed-off-by:

The adreno_load_gpu() path is guarded by an error check on adreno_load_fw(). This function is responsible for loading Qualcomm-only-signed binaries (e.g. SQE and GMU FW for A6XX), but it does not take the vendor-signed ZAP blob into account. By embedding the SQE (and GMU, if necessary) firmware into the initrd/kernel, we can trigger and unfortunate path that would not bail out early and proceed with gpu->hw_init(). That will fail, as the ZAP loader path will not find the firmware and return back to adreno_load_gpu(). This error path involves pm_runtime_put_sync() which then calls idle() instead of suspend(). This is suboptimal, as it means that we're not going through the clean shutdown sequence. With at least A619_holi, this makes the GPU not wake up until it goes through at least one more start-fail-stop cycle. The pm_runtime_put_sync that appears in the error path actually does not guarantee that because of the earlier enabling of runtime autosuspend. Fix that by using pm_runtime_put_sync_suspend to force a clean shutdown. Test cases: 1. All firmware baked into kernel 2. error loading ZAP fw in initrd -> load from rootfs at DE start Both succeed on A619_holi (SM6375) and A630 (SDM845).

Recently I contributed the switch to OPP API for all Adreno generations. I did however also skip over the fact that GPUs with a GMU don't specify a core clock of any kind in the GPU node. While that didn't break anything, it did introduce unwanted spam in the dmesg: adreno 5000000.gpu: error -ENOENT: _opp_set_clknames: Couldn't find clock with name: core_clk Guard the entire logic so that it's not used with GMU-equipped GPUs.

The commit e25e92e0 ("drm/msm: devcoredump iommu fault support") enabled SMMU stalling to collect GPU state, but only for a6xx. It tied enabling the stall with tha per-instance pagetables creation.
