2019-01-25drm/sched: Refactor ring mirror list handling.Andrey Grodzovsky
Decauple sched threads stop and start and ring mirror list handling from the policy of what to do about the guilty jobs. When stoppping the sched thread and detaching sched fences from non signaled HW fenes wait for all signaled HW fences to complete before rerunning the jobs. v2: Fix resubmission of guilty job into HW after refactoring. v4: Full restart for all the jobs, not only from guilty ring. Extract karma increase into standalone function. v5: Rework waiting for signaled jobs without relying on the job struct itself as those might already be freed for non 'guilty' job's schedulers. Expose karma increase to drivers. v6: Use list_for_each_entry_safe_continue and drm_sched_process_job in case fence already signaled. Call drm_sched_increase_karma only once for amdgpu and add documentation. v7: Wait only for the latest job's fence.

According to Dave, once you've started an L2T flush, all L2T accesses will be blocked until the flush completes.

2018-12-03drm/v3d: Add more tracepoints for V3D GPU rendering.Eric Anholt
The core scheduler tells us when the job is pushed to the scheduler's queue, and I had the job_run functions saying when they actually queue the job to the hardware. By adding tracepoints for the very top of the ioctls and the IRQs signaling job completion, "perf record -a -e v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty decent timeline.

2018-11-30drm/v3d: Add support for submitting jobs to the TFU.Eric Anholt
The TFU can copy from raster, UIF, and SAND input images to UIF output images, with optional mipmap generation. This will certainly be useful for media EGL image input, but is also useful immediately for mipmap generation without bogging the V3D core down. For now we only run the queue 1 job deep, and don't have any hang recovery (though I don't think we should need it, with TFU). Queuing multiple jobs in the HW will require synchronizing the YUV coefficient regs updates since they don't get FIFOed with the job. v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain why TFU is AUTH, clarify the syncing docs, drop the unused TFU interrupt regs (you're expected to use the hub's), don't take &bo->base for NULL bos. v3: Fix a little whitespace alignment (noticed by checkpatch), rebase on drm_sched_job_cleanup() changes.

into drm-next Main changes for 4.18. I'd like to do a separate pull for vega20 later this week or next. Highlights: - Reserve pre-OS scanout buffer during init for seemless transition from console to driver - VEGAM support - Improved GPU scheduler documentation - Initial gfxoff support for raven - SR-IOV fixes - Default to non-AGP on PowerPC for radeon - Fine grained clock voltage control for vega10 - Power profiles for vega10 - Further clean up of powerplay/driver interface - Underlay fixes - Display link bw updates - Gamma fixes - Scatter/Gather display support on CZ/ST - Misc bug fixes and clean ups [airlied: fixup v3d vs scheduler API change] Link: https://patchwork.freedesktop.org/patch/msgid/20180515185450.1113-1-alexander.deucher@amd.com Signed-off-by: Dave Airlie <airlied@redhat.com>
2018-05-03drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+Eric Anholt
This driver will be used to support Mesa on the Broadcom 7268 and 7278 platforms. V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's complicated CL/shader validation scheme. This massively changes the GEM behavior, so I've forked off to a new driver. v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild test robot. Drop personal git link from MAINTAINERS. Don't double-map dma-buf imported BOs. Add kerneldoc about needing MMU eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup to mmap time. Use drm_dev_init instead of _alloc. Use ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage, since we don't modeset. Switch page tables back to WC (debug change to coherent had slipped in). Switch drm_gem_object_unreference_unlocked() to drm_gem_object_put_unlocked(). Simplify overflow mem handling by not sharing overflow mem between jobs. v3: no changes v4: align submit_cl to 64 bits (review by airlied), check zero flags in other ioctls.
