* drm/scheduler: rework job destructionChristian König2019-05-028-85/+102
| | | | | | | | | | | | | | | | | | | | | | | We now destroy finished jobs from the worker thread to make sure that we never destroy a job currently in timeout processing. By this we avoid holding lock around ring mirror list in drm_sched_stop which should solve a deadlock reported by a user. v2: Remove unused variable. v4: Move guilty job free into sched code. v5: Move sched->hw_rq_count to drm_sched_start to account for counter decrement in drm_sched_stop even when we don't call resubmit jobs if guily job did signal. v6: remove unused variable Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=109692 Acked-by: Chunming Zhou <david1.zhou@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/1555599624-12285-3-git-send-email-andrey.grodzovsky@amd.com
* drm/atomic-helper: Bump vblank timeout to 100 msLinus Walleij2019-04-301-1/+1
| | | | | | | | | | | | | | | The 50 ms default timeout waiting for vblanks is too small for the first vblank from the ST-Ericsson MCDE display controller over DSI. Presumably this is because the DSI display is command-mode only and the state machine will take some time setting up its state for the first display update, and we hit a timeout. 100 ms makes it pass without problems.

| | | | | | | | | | | | | This patch adds Samsung S6E63M0 AMOLED LCD panel driver, connected over spi. It's based on already removed, non-device-tree S6E63M0 driver and panel-samsung-ld9040. It can be found for example in some of Samsung Aries based phones.

* drm/v3d: Add missing implicit synchronization.Eric Anholt2019-04-183-61/+53
| | | | | | | | | | | | | | | | | | | | | It is the expectation of existing userspace (X11 + Mesa, in particular) that jobs submitted to the kernel against a shared BO will get implicitly synchronized by their submission order. If we want to allow clever userspace to disable implicit synchronization, we should do that under its own submit flag (as amdgpu and lima do). Note that we currently only implicitly sync for the rendering pass, not binning -- if you texture-from-pixmap in the binning vertex shader (vertex coordinate generation), you'll miss out on synchronization. Fixes flickering when multiple clients are running in parallel, particularly GL apps and compositors. v2: Fix a missing refcount on the CSD done fence for L2 cleaning.

* drm/v3d: Add support for compute shader dispatch.Eric Anholt2019-04-1810-19/+531
| | | | | | | | | | | | | | | | | | | | | | | | | The compute shader dispatch interface is pretty simple -- just pass in the regs that userspace has passed us, with no CLs to run. However, with no CL to run it means that we need to do manual cache flushing of the L2 after the HW execution completes (for SSBO, atomic, and image_load_store writes that are the output of compute shaders). This doesn't yet expose the L2 cache's ability to have a region of the address space not write back to memory (which could be used for shared_var storage). So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing the ES31 tests), and on the kernel side on 7278 (failing atomic compswap tests in a way that doesn't reproduce on simpenrose). v2: Fix excessive allocation for the clean_job (reported by Dan Carpenter). Keep refs on jobs until clean_job is finished, to avoid spurious MMU errors if the output BOs are freed by userspace before L2 cleaning is finished.

* drm/v3d: Refactor job management.Eric Anholt2019-04-184-329/+380
| | | | | | | | | | | | | | The CL submission had two jobs embedded in an exec struct. When I added TFU support, I had to replicate some of the exec stuff and some of the job stuff. As I went to add CSD, it became clear that actually what was in exec should just be in the two CL jobs, and it would let us share a lot more code between the 4 queues. v2: Fix missing error path in TFU ioctl's bo[] allocation.
