2024-09-02drm/i915: Do not attempt to load the GSC multiple timesDaniele Ceraolo Spurio
If the GSC FW fails to load the GSC HW hangs permanently; the only ways to recover it are FLR or D3cold entry, with the former only being supported on driver unload and the latter only on DGFX, for which we don't need to load the GSC. Therefore, if GSC fails to load there is no need to try again because the HW is stuck in the error state and the submission to load the FW would just hang the GSCCS. Note that, due to wa_14015076503, on MTL the GuC escalates all GSCCS hangs to full GT resets, which would trigger a new attempt to load the GSC FW in the post-reset HW re-init; this issue is also fixed by not attempting to load the GSC FW after an error.

2024-09-02drm/panfrost: Add cycle counter job requirementMary Guillemard
Extend the uAPI with a new job requirement flag for cycle counters. This requirement is used by userland to indicate that a job requires cycle counters or system timestamp to be propagated. (for use with write value timestamp jobs) We cannot enable cycle counters unconditionally as this would result in an increase of GPU power consumption. As a result, they should be left off unless required by the application. If a job requires cycle counters or system timestamps propagation, we must enable cycle counting before issuing a job and disable it right after the job completes. Since this extends the uAPI and because userland needs a way to advertise features like VK_KHR_shader_clock conditionally, we bumps the driver minor version. v2: - Rework commit message - Squash uAPI changes and implementation in this commit - Simplify changes based on Steven Price comments v3: - Add Steven Price r-b - Fix a codestyle issue Signed-off-by: Mary Guillemard <mary.guillemard@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Tested-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240819080224.24914-3-mary.guillemard@collabora.com

2024-09-01mm: kvmalloc: align kvrealloc() with krealloc()Danilo Krummrich
Besides the obvious (and desired) difference between krealloc() and kvrealloc(), there is some inconsistency in their function signatures and behavior: - krealloc() frees the memory when the requested size is zero, whereas kvrealloc() simply returns a pointer to the existing allocation. - krealloc() behaves like kmalloc() if a NULL pointer is passed, whereas kvrealloc() does not accept a NULL pointer at all and, if passed, would fault instead. - krealloc() is self-contained, whereas kvrealloc() relies on the caller to provide the size of the previous allocation. Inconsistent behavior throughout allocation APIs is error prone, hence make kvrealloc() behave like krealloc(), which seems superior in all mentioned aspects. Besides that, implementing kvrealloc() by making use of krealloc() and vrealloc() provides oppertunities to grow (and shrink) allocations more efficiently. For instance, vrealloc() can be optimized to allocate and map additional pages to grow the allocation or unmap and free unused pages to shrink the allocation.

2024-09-02drm/msm/dpu: Configure DP INTF/PHY selectorDmitry Baryshkov
Some platforms provides a mechanism for configuring the mapping between (one or two) DisplayPort intfs and their PHYs. In particular SC8180X requires this to be configured, since on this platform there are fewer controllers than PHYs. The change implements the logic for optionally configuring which PHY each of the DP INTFs should be connected to and marks the SC8180X DPU to program 2 entries. For now the request is simply to program the mapping 1:1, any support for alternative mappings is left until the use case arrise. Note that e.g. msm-4.14 unconditionally maps INTF 0 to PHY 0 on all platforms, so perhaps this is needed in order to get DisplayPort working on some other platforms as well.

2024-09-01drm/msm/a5xx: workaround early ring-buffer emptiness checkVladimir Lypak
There is another cause for soft lock-up of GPU in empty ring-buffer: race between GPU executing last commands and CPU checking ring for emptiness. On GPU side IRQ for retire is triggered by CACHE_FLUSH_TS event and RPTR shadow (which is used to check ring emptiness) is updated a bit later from CP_CONTEXT_SWITCH_YIELD. Thus if GPU is executing its last commands slow enough or we check that ring too fast we will miss a chance to trigger switch to lower priority ring because current ring isn't empty just yet. This can escalate to lock-up situation described in previous patch. To work-around this issue we keep track of last submit sequence number for each ring and compare it with one written to memptrs from GPU during execution of CACHE_FLUSH_TS event.

2024-09-01drm/msm/a5xx: fix races in preemption evaluation stageVladimir Lypak
On A5XX GPUs when preemption is used it's invietable to enter a soft lock-up state in which GPU is stuck at empty ring-buffer doing nothing. This appears as full UI lockup and not detected as GPU hang (because it's not). This happens due to not triggering preemption when it was needed. Sometimes this state can be recovered by some new submit but generally it won't happen because applications are waiting for old submits to retire. One of the reasons why this happens is a race between a5xx_submit and a5xx_preempt_trigger called from IRQ during submit retire. Former thread updates ring->cur of previously empty and not current ring right after latter checks it for emptiness. Then both threads can just exit because for first one preempt_state wasn't NONE yet and for second one all rings appeared to be empty. To prevent such situations from happening we need to establish guarantee for preempt_trigger to make decision after each submit or retire. To implement this we serialize preemption initiation using spinlock. If switch is already in progress we need to re-trigger preemption when it finishes.

2024-09-01drm/msm/a5xx: properly clear preemption records on resumeVladimir Lypak
Two fields of preempt_record which are used by CP aren't reset on resume: "data" and "info". This is the reason behind faults which happen when we try to switch to the ring that was active last before suspend. In addition those faults can't be recovered from because we use suspend and resume to do so (keeping values of those fields again).

2024-09-01drm/msm/a5xx: disable preemption in submits by defaultVladimir Lypak
Fine grain preemption (switching from/to points within submits) requires extra handling in command stream of those submits, especially when rendering with tiling (using GMEM). However this handling is missing at this point in mesa (and always was). For this reason we get random GPU faults and hangs if more than one priority level is used because local preemption is enabled prior to executing command stream from submit. With that said it was ahead of time to enable local preemption by default considering the fact that even on downstream kernel it is only enabled if requested via UAPI.

2024-09-01drm/msm/adreno: Assign msm_gpu->pdev earlier to avoid nullptrsKonrad Dybcio
There are some cases, such as the one uncovered by Commit 46d4efcccc68 ("drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails") where msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL); is called on gpu->pdev == NULL, as the GPU device has not been fully initialized yet. Turns out that there's more than just the aforementioned path that causes this to happen (e.g. the case when there's speedbin data in the catalog, but opp-supported-hw is missing in DT). Assigning msm_gpu->pdev earlier seems like the least painful solution to this, therefore do so.
