If userspace asked for a timeout greater than zero, but less than a jiffy, they clearly weren't planning on spinning. So it is better to round up to one. This fixes an issue with supertuxkart that was (for some reason) spinning on a gl sync with 1ms timeout.

Make sure to destroy the workqueue also in case of early errors during bind (e.g. a subcomponent failing to bind). Since commit c3b790ea ("drm: Manage drm_mode_config_init with drmm_") the mode config will be freed when the drm device is released also when using the legacy interface, but add an explicit cleanup for consistency and to facilitate backporting.

This reverts commit 86365003. A recent commit tried to address a drm device leak in the early msm_drm_uninit() error paths but ended up making things worse. Specifically, it moved the drm device reference put in msm_drm_uninit() to msm_drm_init() which means that the drm would now be leaked on normal unbind. For reasons that were never spelled out, it also added kms NULL pointer checks to a couple of helper functions that had nothing to do with the paths modified by the patch. Instead of trying to salvage this incrementally, let's revert the bad commit so that clean and backportable fixes can be added in its place.

This reverts commit 643b7d08. A recent patch that tried to fix up the msm_drm_init() paths with respect to the workqueue but only ended up making things worse: First, the newly added calls to msm_drm_uninit() on early errors would trigger NULL-pointer dereferences, for example, as the kms pointer would not have been initialised. (Note that these paths were also modified by a second broken error handling patch which in effect cancelled out this part when merged.) Second, the newly added allocation sanity check would still leak the previously allocated drm device. Instead of trying to salvage what was badly broken (and clearly not tested), let's revert the bad commit so that clean and backportable fixes can be added in its place.

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.

-
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.

As the finished fence is the one that is exposed to userspace, and therefore the one that other operations, like atomic update, would block on, we need to propagate the deadline from from the finished fence to the actual hw fence. v2: Split into drm_sched_fence_set_parent() (ckoenig) v3: Ensure a thread calling drm_sched_fence_set_deadline_finished() sees fence->parent set before drm_sched_fence_set_parent() does this test_bit(DMA_FENCE_FLAG_HAS_DEADLINE_BIT).
