* drm/msm: Fix dereference of pointer minor before null checkColin Ian King2025-08-071-4/+7
| | | | | | | | | | | | | Currently the pointer minor is being dereferenced before it is null checked, leading to a potential null pointer dereference issue. Fix this by dereferencing the pointer only after it has been null checked. Also Replace minor->dev with dev.

* drm/msm: Temporarily disable stall-on-fault after a page faultConnor Abbott2025-06-091-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When things go wrong, the GPU is capable of quickly generating millions of faulting translation requests per second. When that happens, in the stall-on-fault model each access will stall until it wins the race to signal the fault and then the RESUME register is written. This slows processing page faults to a crawl as the GPU can generate faults much faster than the CPU can acknowledge them. It also means that all available resources in the SMMU are saturated waiting for the stalled transactions, so that other transactions such as transactions generated by the GMU, which shares translation resources with the GPU, cannot proceed. This causes a GMU watchdog timeout, which leads to a failed reset because GX cannot collapse when there is a transaction pending and a permanently hung GPU. On older platforms with qcom,smmu-v2, it seems that when one transaction is stalled subsequent faulting transactions are terminated, which avoids this problem, but the MMU-500 follows the spec here. To work around these problems, disable stall-on-fault as soon as we get a page fault until a cooldown period after pagefaults stop. This allows the GMU some guaranteed time to continue working. We only use stall-on-fault to halt the GPU while we collect a devcoredump and we always terminate the transaction afterward, so it's fine to miss some subsequent page faults. We also keep it disabled so long as the current devcoredump hasn't been deleted, because in that case we likely won't capture another one if there's a fault. After this commit HFI messages still occasionally time out, because the crashdump handler doesn't run fast enough to let the GMU resume, but the driver seems to recover from it. This will probably go away after the HFI timeout is increased.

* drm/msm: Implement fbdev emulation as in-kernel clientThomas Zimmermann2023-04-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move code from ad-hoc fbdev callbacks into DRM client functions and remove the old callbacks. The functions instruct the client to poll for changed output or restore the display. The DRM core calls both, the old callbacks and the new client helpers, from the same places. The new functions perform the same operation as before, so there's no change in functionality. Replace all code that initializes or releases fbdev emulation throughout the driver. Instead initialize the fbdev client by a single call to msm_fbdev_setup() after msm has registered its DRM device. As in most drivers, msm's fbdev emulation now acts like a regular DRM client. The fbdev client setup consists of the initial preparation and the hot-plugging of the display. The latter creates the fbdev device and sets up the fbdev framebuffer. The setup performs display hot-plugging once. If no display can be detected, DRM probe helpers re-run the detection on each hotplug event. A call to drm_dev_unregister() releases the client automatically. No further action is required within msm. If the fbdev framebuffer has been fully set up, struct fb_ops.fb_destroy implements the release. For partially initialized emulation, the fbdev client reverts the initial setup. v2: * handle fbdev module parameter correctly (kernel test robot) Signed-off-by: Thomas Zimmermann <[email protected]> Reviewed-by: Dmitry Baryshkov <[email protected]> Tested-by: Dmitry Baryshkov <[email protected]> # RB5 Patchwork: https://patchwork.freedesktop.org/patch/530560/ Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Dmitry Baryshkov <[email protected]>

* drm/msm/shrinker: Only iterate dontneed objsRob Clark2020-11-211-1/+2
| | | | | | | | | | | | | | | | In situations where the GPU is mostly idle, all or nearly all buffer objects will be in the inactive list. But if the system is under memory pressure (from something other than GPU), we could still get a lot of shrinker calls. Which results in traversing a list of thousands of objs and in the end finding nothing to shrink. Which isn't so efficient. Instead split the inactive_list into two lists, one inactive objs which are shrinkable, and a second one for those that are not. This way we can avoid traversing objs which we know are not shrinker candidates. v2: Fix inverted logic think-o Signed-off-by: Rob Clark <[email protected]>

|/ | | | | | | | | | The msm_gpu_open() function should free "show_priv" on error or it causes static checker warnings.

* drm/msm/gpu: Capture the GPU state on a GPU hangJordan Crouse2018-07-301-2/+3
| | | | | | | | | | | Capture the GPU state on a GPU hang and store it for later playback via the devcoredump facility. Only one crash state is stored at a time on the assumption that the first hang is usually the most interesting. The existing crash state can be cleared after capturing it and then a new one will be captured on the next hang.

* drm/msm/gpu: Convert the GPU show function to use the GPU stateJordan Crouse2018-07-301-8/+84
| | | | | | | | | | | Convert the existing GPU show function to use the GPU state to dump the information rather than reading it directly from the hardware. This will require an additional step to capture the state before dumping it for the existing nodes but it will greatly facilitate reusing the same code for dumping a previously captured state from a GPU hang.

| | | | | | | | Add some debugfs to dump out PFP and ME microcontroller state, as well as some of the queues (MEQ and ROQ). Also add a debugfs file to trigger a GPU reset (and reloading the firmware on next submit). Signed-off-by: Rob Clark <[email protected]>

| | | | | | | | | | | | Move the contents of msm_debugfs_cleanup() to msm_drm_uninit() to free up the drm_driver->debugfs_cleanup callback. Also remove the mdp_kms_funcs->debugfs_cleanup callback which has no users.

| | | | | | | | | | | | | drm_debugfs_cleanup() now removes all minor->debugfs_list entries automatically, so it's not necessary to call drm_debugfs_remove_files(). Additionally it uses debugfs_remove_recursive() to clean up the debugfs files, so no need to do that.

* drm/mm: Convert to drm_printerDaniel Vetter2016-12-301-1/+5
| | | | | | | | | | | | | | | | | | | | | | Including all drivers. I thought about keeping small compat functions to avoid having to change all drivers. But I really like the drm_printer idea, so figured spreading it more widely is a good thing. v2: Review from Chris: - Natural argument order and better name for drm_mm_print. - show_mm() macro in the selftest.
