2019-10-23drm/v3d: Fix memory leak in v3d_submit_cl_ioctlNavid Emamdoost1-1/+4
In the impelementation of v3d_submit_cl_ioctl() there are two memory leaks. One is when allocation for bin fails, and the other is when bin initialization fails. If kcalloc fails to allocate memory for bin then render->base should be put. Also, if v3d_job_init() fails to initialize bin->base then allocated memory for bin should be released.

2019-09-19drm/v3d: clean caches at the end of render jobs on request from user spaceIago Toral Quiroga2-8/+49
Extends the user space ioctl for CL submissions so it can include a request to flush the cache once the CL execution has completed. Fixes memory write violation messages reported by the kernel in workloads involving shader memory writes (SSBOs, shader images, scratch, etc) which sometimes also lead to GPU resets during Piglit and CTS workloads. v2: if v3d_job_init() fails we need to kfree() the job instead of v3d_job_put() it (Eric Anholt). v3 (Eric Anholt): - Drop _FLAG suffix from the new flag name. - Add a new param so userspace can tell whether cache flushing is implemented in the kernel.

2019-05-16drm/v3d: Fix and extend MMU error handling.Eric Anholt5-7/+37
We were setting the wrong flags to enable PTI errors, so we were seeing reads to invalid PTEs show up as write errors. Also, we weren't turning on the interrupts. The AXI IDs we were dumping included the outstanding write number and so they looked basically random. And the VIO_ADDR decoding was based on the MMU VA_WIDTH for the first platform I worked on and was wrong on others. In short, this was a thorough mess from early HW enabling. Tested on V3D 4.1 and 4.2 with intentional L2T, CLE, PTB, and TLB faults.

2019-04-18drm/v3d: Add missing implicit synchronization.Eric Anholt3-61/+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.

2019-04-18drm/v3d: Add support for compute shader dispatch.Eric Anholt9-19/+503
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.

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.

2019-01-26drm/sched: Refactor ring mirror list handling.Andrey Grodzovsky1-5/+8
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.

2018-12-07drm/v3d: Drop the wait for L2T flush to complete.Eric Anholt1-4/+4
According to Dave, once you've started an L2T flush, all L2T accesses will be blocked until the flush completes. This fixes a consistent 3-4ms stall between the ioctl and running the job, and 3DMMES Taiji goes from 27fps to 110fps. v2: Leave a note about why we don't need to wait for completion.

This reverts commit 9a09a42369a4a37a959c051d8e1a1f948c1529a4. The whole interface isn't thought through. Since this function can't fail we actually can't allocate an object to store the sync point. Sorry, I should have taken the lead on this from the very beginning and reviewed it more thoughtfully. Going to propose a new interface as a follow up change.

2018-12-03drm/v3d: Add more tracepoints for V3D GPU rendering.Eric Anholt3-3/+121
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.

v3d_bo_get_pages() checks this to decide to map the imported buffer instead of the backing shmem file. The caller was about to set this value anyway, and there's no error path in between. Ideally we wouldn't even allocate the shmem file for our imports, but that's a more invasive fix.

2018-12-01drm/v3d: Add support for submitting jobs to the TFU.Eric Anholt7-51/+402
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.
