* drm/vram-helper: Unexport drm_vram_helper_{alloc,release}_mm()Thomas Zimmermann2021-07-052-10/+3

* drm/dbi: Print errors for mipi_dbi_command()Linus Walleij2021-07-051-1/+6
| | | | | | | | | | | | | | | | | The macro mipi_dbi_command() does not report errors unless you wrap it in another macro to do the error reporting. Report a rate-limited error so we know what is going on. After this any code wishing to send command arrays can rely on mipi_dbi_command() providing an appropriate error message if something goes wrong.

* drm/panfrost: Increase the AS_ACTIVE polling timeoutBoris Brezillon2021-07-011-1/+1
| | | | | | | | | | | | | | | | | Experience has shown that 1ms is sometimes not enough, even when the GPU is running at its maximum frequency, not to mention that an MMU operation might take longer if the GPU is running at a lower frequency, which is likely to be the case if devfreq is active.

* drm/panfrost: Simplify the reset serialization logicBoris Brezillon2021-07-012-123/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we can pass our own workqueue to drm_sched_init(), we can use an ordered workqueue on for both the scheduler timeout tdr and our own reset work (which we use when the reset is not caused by a fault/timeout on a specific job, like when we have AS_ACTIVE bit stuck). This guarantees that the timeout handlers and reset handler can't run concurrently which drastically simplifies the locking. v5: * Don't call cancel_delayed_timeout() in the reset path (those works are canceled in drm_sched_stop()) v4: * Actually pass the reset workqueue to drm_sched_init() * Don't call cancel_work_sync() in panfrost_reset(). It will deadlock since it might be called from the reset work, which is executing and cancel_work_sync() will wait for the handler to return.

* drm/sched: Allow using a dedicated workqueue for the timeout/fault tdrBoris Brezillon2021-07-017-15/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mali Midgard/Bifrost GPUs have 3 hardware queues but only a global GPU reset. This leads to extra complexity when we need to synchronize timeout works with the reset work. One solution to address that is to have an ordered workqueue at the driver level that will be used by the different schedulers to queue their timeout work. Thanks to the serialization provided by the ordered workqueue we are guaranteed that timeout handlers are executed sequentially, and can thus easily reset the GPU from the timeout handler without extra synchronization. v5: * Add a new paragraph to the timedout_job() method v3: * New patch v4: * Actually use the timeout_wq to queue the timeout work Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Reviewed-by: Lucas Stach <l.stach@pengutronix.de> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Christian König <christian.koenig@amd.com> Cc: Qiang Yu <yuq825@gmail.com> Cc: Emma Anholt <emma@anholt.net> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: "Christian König" <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210630062751.2832545-3-boris.brezillon@collabora.com

* drm: Don't test for IRQ support in VBLANK ioctlsThomas Zimmermann2021-06-292-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | For KMS drivers, replace the IRQ check in VBLANK ioctls with a check for vblank support. IRQs might be enabled wthout vblanking being supported. This change also removes the DRM framework's only dependency on IRQ state for non-legacy drivers. For legacy drivers with userspace modesetting, the original test remains in drm_wait_vblank_ioctl(). v4: * avoid preprocessor ifdef in drm_wait_vblank_ioctl() (Jani, Thierry) v3: * optimize test in drm_wait_vblank_ioctl() for KMS case (Liviu) * update docs for drm_irq_uninstall() v2: * keep the old test for legacy drivers in drm_wait_vblank_ioctl() (Daniel) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Liviu Dudau <liviu.dudau@arm.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20210625082222.3845-5-tzimmermann@suse.de
