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.

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.

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: Jessica Zhang <quic_jesszhan@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Marijn Suijten <marijn.suijten@somainline.org> Patchwork: https://patchwork.freedesktop.org/patch/523602/ Link: https://lore.kernel.org/r/20230221184256.1436-2-quic_jesszhan@quicinc.comSigned-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

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).

This series adds a deadline hint to fences, so realtime deadlines such as vblank can be communicated to the fence signaller for power/ frequency management decisions. This is partially inspired by a trick i915 does, but implemented via dma-fence for a couple of reasons: 1) To continue to be able to use the atomic helpers 2) To support cases where display and gpu are different drivers See https://patchwork.freedesktop.org/series/93035/ This does not yet add any UAPI, although this will be needed in a number of cases: 1) Workloads "ping-ponging" between CPU and GPU, where we don't want the GPU freq governor to interpret time stalled waiting for GPU as "idle" time 2) Cases where the compositor is waiting for fences to be signaled before issuing the atomic ioctl, for example to maintain 60fps cursor updates even when the GPU is not able to maintain that framerate.

Since the LRU lock is already acquired when moving an obj between LRUs, we can use it to protect pin_count and madv, without any significant change in locking (ie. it just expands the scope of the lock by a hand- ful of instructions). This prepares the way to decrement the pin_count in the job_run() path without needing to hold the obj lock, to avoid a potential deadlock (or rather stall) caused by the fence-signaling path (job_run()) blocking on shrinker/reclaim. (Only a stall because the wait for fence signaling wait_for_idle() is not infinite.)
