2023-04-06drm/msm/dsi: Remove custom DSI config handlingKonrad Dybcio2-6/+2
Now that the only user is handled by common code, remove the option to specify custom handlers through match data.

The configs are identical, other than the number of *maximum* DSI hosts allowed. This isn't an issue, unless somebody deliberately tries to access the inexistent host by adding a dt node for it. Remove the SC7180 struct and point the hw revision match to the SDM845's one. On a note, this could have been done back when 7180 support was introduced.

2023-04-06drm/msm/dsi: Fix DSI index detection when version clash occursKonrad Dybcio3-19/+48
Currently, we allow for MAX_DSI entries in io_start to facilitate for MAX_DSI number of DSI hosts at different addresses. The configuration is matched against the DSI CTRL hardware revision read back from the component. We need a way to resolve situations where multiple SoCs with different register maps may use the same version of DSI CTRL. In preparation to do so, make msm_dsi_config a 2d array where each entry represents a set of configurations adequate for a given SoC. This is totally fine to do, as the only differentiating factors between same-version-different-SoCs configurations are the number of DSI hosts (1 or 2, at least as of today) and the set of base registers. The regulator setup is the same, because the DSI hardware is the same, regardless of the SoC it was implemented in. In addition to that, update the matching logic such that it will loop over VARIANTS_MAX variants, making sure they are all taken into account.

2023-04-03drm/msm/adreno: adreno_gpu: Use suspend() instead of idle() on load errorKonrad Dybcio1-1/+1
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.

2023-03-25dma-buf/dma-fence: Add deadline awarenessRob Clark3-0/+87
Add a way to hint to the fence signaler of an upcoming deadline, such as vblank, which the fence waiter would prefer not to miss. This is to aid the fence signaler in making power management decisions, like boosting frequency as the deadline approaches and awareness of missing deadlines so that can be factored in to the frequency scaling. v2: Drop dma_fence::deadline and related logic to filter duplicate deadlines, to avoid increasing dma_fence size. The fence-context implementation will need similar logic to track deadlines of all the fences on the same timeline. [ckoenig] v3: Clarify locking wrt. set_deadline callback v4: Clarify in docs comment that this is a hint v5: Drop DMA_FENCE_FLAG_HAS_DEADLINE_BIT. v6: More docs v7: Fix typo, clarify past deadlines Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Christian König <christian.koenig@amd.com> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.com> Reviewed-by: Bagas Sanjaya <bagasdotme@gmail.com>

2023-03-20drm/msm/adreno: fix runtime PM imbalance at gpu loadJohan Hovold1-4/+12
A recent commit moved enabling of runtime PM to GPU load time (first open()) but failed to update the error paths so that runtime PM is disabled if initialisation of the GPU fails. This would trigger a warning about the unbalanced disable count on the next open() attempt. Note that pm_runtime_put_noidle() is sufficient to balance the usage count when pm_runtime_put_sync() fails (and is chosen over pm_runtime_resume_and_get() for consistency reasons).
