treewide: Add missing includes masked by cgroup -> bpf dependency

2021-12-03T18:58:13+00:00

cgroup.h (therefore swap.h, therefore half of the universe) includes bpf.h which in turn includes module.h and slab.h. Since we're about to get rid of that dependency we need to clean things up. v2: drop the cpu.h include from cacheinfo.h, it's not necessary and it makes riscv sensitive to ordering of include files.

drm/lima: use scheduler dependency tracking

2021-08-30T08:58:20+00:00

Nothing special going on here. Aside reviewing the code, it seems like drm_sched_job_arm() should be moved into lima_sched_context_queue_task and put under some mutex together with drm_sched_push_job(). See the kerneldoc for drm_sched_push_job(). v2: Rebase over renamed functions to add dependencies.

drm/sched: drop entity parameter from drm_sched_push_job

2021-08-30T08:54:45+00:00

Originally a job was only bound to the queue when we pushed this, but now that's done in drm_sched_job_init, making that parameter entirely redundant. Remove it. The same applies to the context parameter in lima_sched_context_queue_task, simplify that too. v2: Rebase on top of msm adopting drm/sched Reviewed-by: Christian König Acked-by: Emma Anholt Acked-by: Melissa Wen Reviewed-by: Steven Price (v1) Reviewed-by: Boris Brezillon (v1) Signed-off-by: Daniel Vetter Cc: Lucas Stach Cc: Russell King Cc: Christian Gmeiner Cc: Qiang Yu Cc: Rob Herring Cc: Tomeu Vizoso Cc: Steven Price Cc: Alyssa Rosenzweig Cc: Emma Anholt Cc: David Airlie Cc: Daniel Vetter Cc: Sumit Semwal Cc: "Christian König" Cc: Alex Deucher Cc: Nirmoy Das Cc: Dave Airlie Cc: Chen Li Cc: Lee Jones Cc: Deepak R Varma Cc: Kevin Wang Cc: Luben Tuikov Cc: "Marek Olšák" Cc: Maarten Lankhorst Cc: Andrey Grodzovsky Cc: Dennis Li Cc: Boris Brezillon Cc: etnaviv@lists.freedesktop.org Cc: lima@lists.freedesktop.org Cc: linux-media@vger.kernel.org Cc: linaro-mm-sig@lists.linaro.org Cc: Rob Clark Cc: Sean Paul Cc: Melissa Wen Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20210805104705.862416-6-daniel.vetter@ffwll.ch

drm/sched: Split drm_sched_job_init

2021-08-30T08:50:44+00:00

This is a very confusingly named function, because not just does it init an object, it arms it and provides a point of no return for pushing a job into the scheduler. It would be nice if that's a bit clearer in the interface. But the real reason is that I want to push the dependency tracking helpers into the scheduler code, and that means drm_sched_job_init must be called a lot earlier, without arming the job. v2: - don't change .gitignore (Steven) - don't forget v3d (Emma) v3: Emma noticed that I leak the memory allocated in drm_sched_job_init if we bail out before the point of no return in subsequent driver patches. To be able to fix this change drm_sched_job_cleanup() so it can handle being called both before and after drm_sched_job_arm(). Also improve the kerneldoc for this. v4: - Fix the drm_sched_job_cleanup logic, I inverted the booleans, as usual (Melissa) - Christian pointed out that drm_sched_entity_select_rq() also needs to be moved into drm_sched_job_arm, which made me realize that the job->id definitely needs to be moved too. Shuffle things to fit between job_init and job_arm. v5: Reshuffle the split between init/arm once more, amdgpu abuses drm_sched.ready to signal gpu reset failures. Also document this somewhat. (Christian) v6: Rebase on top of the msm drm/sched support. Note that the drm_sched_job_init() call is completely misplaced, and hence also the split-out drm_sched_entity_push_job(). I've put in a FIXME which the next patch will address. v7: Drop the FIXME in msm, after discussions with Rob I agree it shouldn't be a problem where it is now.

drm/sched: Allow using a dedicated workqueue for the timeout/fault tdr

2021-07-01T06:53:25+00:00

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 Signed-off-by: Boris Brezillon Reviewed-by: Steven Price Reviewed-by: Lucas Stach Acked-by: Daniel Vetter Acked-by: Christian König Cc: Qiang Yu Cc: Emma Anholt Cc: Alex Deucher Cc: "Christian König" Link: https://patchwork.freedesktop.org/patch/msgid/20210630062751.2832545-3-boris.brezillon@collabora.com

treewide: Add missing semicolons to __assign_str uses

The __assign_str macro has an unusual ending semicolon but the vast majority of uses of the macro already have semicolon termination. $ git grep -P '\b__assign_str\b' | wc -l 551 $ git grep -P '\b__assign_str\b.*;' | wc -l 480 Add semicolons to the __assign_str() uses without semicolon termination and all the other uses without semicolon termination via additional defines that are equivalent to __assign_str() with the eventual goal of removing the semicolon from the __assign_str() macro definition.
