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. Reviewed-by:

In preparation for supporting multiple sets of possible base registers, remove the num_dsi variable. We're comparing the io_start array contents with the reg value from the DTS, so it will either match one of the expected values or don't match against a zero (which we get from partial array initialization).

The point of the previous cleanup was to disallow "qcom,mdss-dsi-ctrl" alone. This however didn't quite work out and the property became undocumented instead of deprecated. Fix that.

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.

Rob Clark authored
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.

Now that everything that controls which LRU an obj lives in *except* the backing pages is protected by the LRU lock, add a special path to unpin in the job_run() path, where we are assured that we already have backing pages and will not be racing against eviction (because the GEM object's dma_resv contains the fence that will be signaled when the submit/job completes).

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.) Signed-off-by:

We need to use the inuse count to track that a BO is pinned until we have the hw_fence. But we want to remove the obj lock from the job_run() path as this could deadlock against reclaim/shrinker (because it is blocking the hw_fence from eventually being signaled). So split that tracking out into a per-vma lock with narrower scope. Signed-off-by:

The flags are only accessed (1) when submit is constructed, before enqueuing to gpu sched (ie. when still visible to only the task calling the submit ioctl), (2) here, where we own a reference to the submit and are serialized on the gpu sched thread, and (3) after the submit is retired and last reference is dropped, which is serialized on the submit's reference count. Hence locking is unneeded here. Signed-off-by:
