However in this case the devfreq infrastructure isn't notified that the GPU is busy. By the time the tick happens the job might well have finished and no time will be accounted for the GPU being busy. Fix this by recording the GPU as busy directly in queue_run_job() in the case where there is a CSG assigned and therefore we just ring the doorbell.

The FW will then call the tiler OOM exception handler, which is supposed to implement incremental rendering (execute an intermediate fragment job to flush the pending primitives, release the tiler memory that was used to store those primitives, and start over from where it stopped). Instead of checking for both ENOMEM and EBUSY, make panthor_heap_grow() return ENOMEM no matter the reason of this allocation failure, the FW doesn't care anyway. v3: - Add R-bs v2: - Make panthor_heap_grow() return -ENOMEM for all kind of allocation failures - Document the panthor_heap_grow() semantics Fixes: de8548813824 ("drm/panthor: Add the scheduler logical block") Signed-off-by: Antonino Maniscalco <antonino.maniscalco@collabora.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Liviu Dudau <liviu.dudau@arm.com> Reviewed-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240502165158.1458959-2-boris.brezillon@collabora.com 2024-05-02drm/panthor: Make sure we handle 'unknown group state' case properlyBoris Brezillon When we check for state values returned by the FW, we only cover part of the 0:7 range. Make sure we catch FW inconsistencies by adding a default to the switch statement, and flagging the group state as unknown in that case. When an unknown state is detected, we trigger a reset, and consider the group as unusable after that point, to prevent the potential corruption from creeping in other places if we continue executing stuff on this context. v2: - Add Steve's R-b - Fix commit message Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Closes: https://lore.kernel.org/dri-devel/3b7fd2f2-679e-440c-81cd-42fc2573b515@moroto.mountain/T/#u Suggested-by: Steven Price <steven.price@arm.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Reviewed-by: Liviu Dudau <liviu.dudau@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240502155248.1430582-1-boris.brezillon@collabora.com 2024-05-02drm/panthor: Kill the faulty_slots variable in panthor_sched_suspend()Boris Brezillon We can use upd_ctx.timedout_mask directly, and the faulty_slots update in the flush_caches_failed situation is never used.

Indeed, the FW only expose a few slots, and the kernel has to give all submission contexts, a chance to execute their jobs. The kernel-side scheduler is timeslice-based, with a round-robin queue per priority level. Job submission is handled with a 1:1 drm_sched_entity:drm_gpu_scheduler, allowing us to delegate the dependency tracking to the core. All the gory details should be documented inline. v6: - Add Maxime's and Heiko's acks - Make sure the scheduler is initialized before queueing the tick work in the MMU fault handler - Keep header inclusion alphabetically ordered v5: - Fix typos - Call panthor_kernel_bo_destroy(group->syncobjs) unconditionally - Don't move the group to the waiting list tail when it was already waiting for a different syncobj - Fix fatal_queues flagging in the tiler OOM path - Don't warn when more than one job timesout on a group - Add a warning message when we fail to allocate a heap chunk - Add Steve's R-b v4: - Check drmm_mutex_init() return code - s/drm_gem_vmap_unlocked/drm_gem_vunmap_unlocked/ in panthor_queue_put_syncwait_obj() - Drop unneeded WARN_ON() in cs_slot_sync_queue_state_locked() - Use atomic_xchg() instead of atomic_fetch_and(0) - Fix typos - Let panthor_kernel_bo_destroy() check for IS_ERR_OR_NULL() BOs - Defer TILER_OOM event handling to a separate workqueue to prevent deadlocks when the heap chunk allocation is blocked on mem-reclaim. This is just a temporary solution, until we add support for non-blocking/failable allocations - Pass the scheduler workqueue to drm_sched instead of instantiating a separate one (no longer needed now that heap chunk allocation happens on a dedicated wq) - Set WQ_MEM_RECLAIM on the scheduler workqueue, so we can handle job timeouts when the system is under mem pressure, and hopefully free up some memory retained by these jobs v3: - Rework the FW event handling logic to avoid races - Make sure MMU faults kill the group immediately - Use the panthor_kernel_bo abstraction for group/queue buffers - Make in_progress an atomic_t, so we can check it without the reset lock held - Don't limit the number of groups per context to the FW scheduler capacity. Fix the limit to 128 for now. - Add a panthor_job_vm() helper - Account for panthor_vm changes - Add our job fence as DMA_RESV_USAGE_WRITE to all external objects (was previously DMA_RESV_USAGE_BOOKKEEP). I don't get why, given we're supposed to be fully-explicit, but other drivers do that, so there must be a good reason - Account for drm_sched changes - Provide a panthor_queue_put_syncwait_obj() - Unconditionally return groups to their idle list in panthor_sched_suspend() - Condition of sched_queue_{,delayed_}work fixed to be only when a reset isn't pending or in progress. - Several typos in comments fixed.
