2019-04-18drm/v3d: Switch the type of job-> to reduce casting.Eric Anholt

2019-04-01drm/v3d: Rename the fence signaled from IRQs to "irq_fence".Eric Anholt
We have another thing called the "done fence" that tracks when the scheduler considers the job done, and having the shared name was confusing.

2019-03-14drm/v3d: Use the new shmem helpers to reduce driver boilerplate.Eric Anholt
The new shmem helpers from Noralf and Rob abstract out a bunch of our BO creation and mapping code. v2: Use the new sgt getter, and flag pages as dirty before freeing. v3: Remove the mismatched put_pages.

2019-03-08drm/v3d: Add support for V3D v4.2.Eric Anholt
No compatible string for it yet, just the version-dependent changes. They've now tied the hub and the core interrupt lines into a single interrupt line coming out of the block. It also turns out I made a mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D itself -- the bridge is going away in favor of an external reset controller in a larger HW module. v2: Use consistent checks for whether we're on 4.2, and fix a leak in an error path. v3: Use more general means of determining if the current 4.2 changes are in place, as apparently other platforms may switch back (noted by Dave). Update the binding doc. v4: Improve error handling for IRQ init.

Now that the base struct drm_gem_object has a reservation_object, use it and remove the private BO one.

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.

2018-10-15drm/v3d: Fix a use-after-free race accessing the scheduler's fences.Eric Anholt
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.

2018-07-05drm/v3d: Delay the scheduler timeout if we're still making progress.Eric Anholt
GTF-GLES2.gtf.GL.acos.acos_float_vert_xvary submits jobs that take 4 seconds at maximum resolution, but we still want to reset quickly if a job is really hung. Sample the CL's current address and the return address (since we call into tile lists repeatedly) and if either has changed then assume we've made progress.

2018-06-21drm/v3d: Remove the bad signaled() implementation.Eric Anholt
Since our seqno value comes from a counter associated with the GPU ring, not the entity (aka client), they'll be completed out of order. There's actually no need for this code at all, since we don't have enable_signaling() and thus DMA_FENCE_SIGNALED_BIT will be set before we could be called.

2018-06-21drm/v3d: Take a lock across GPU scheduler job creation and queuing.Eric Anholt
Between creation and queueing of a job, you need to prevent any other job from being created and queued. Otherwise the scheduler's fences may be signaled out of seqno order. v2: move mutex unlock to the error label.

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.
