| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | This adds just enough performance counter support to measure the clock. We don't have linux kernel drivers for the clock driving the HW, and this was useful for determining that the V3D HW is running on a slow clock, not that the driver was slow.

* | drm/v3d: Fix a use-after-free race accessing the scheduler's fences.Eric Anholt2018-10-152-2/+11
|/ | | | | | | | | | | | Once we push the job, the scheduler could run it and free it. So, if we want to reference their fences, we need to grab them before then. I haven't seen this happen in many days of conformance test runtime, but let's still close the race.
