2019-09-04drm/virtio: switch from ttm to gem shmem helpersGerd Hoffmann
virtio-gpu basically needs a sg_table for the bo, to tell the host where the backing pages for the object are. So the gem shmem helpers are a perfect fit. Some drm_gem_object_funcs need thin wrappers to update the host state, but otherwise the helpers handle everything just fine. Once the fencing was sorted the switch was surprisingly easy and for the most part just removing the ttm code. v4: fix drm_gem_object_funcs name.

2019-09-04drm/virtio: rework virtio_gpu_object_create fencingGerd Hoffmann
Rework fencing workflow. Stop using ttm helpers, use the virtio_gpu_array_* helpers instead. Due to using the gem reservation object it is initialized and ready for use before calling ttm_bo_init. So we can simply use the standard fencing workflow and drop the tricky logic which checks whenever the command is in flight still. v6: rewrite most of the patch.

2019-09-04drm/virtio: rework virtio_gpu_execbuffer_ioctl fencingGerd Hoffmann
Rework fencing workflow, starting with virtio_gpu_execbuffer_ioctl. Stop using ttm helpers, use the virtio_gpu_array_* helpers (which work on the reservation objects directly) instead. Also store the object array in struct virtio_gpu_vbuffer, so we explicitly keep a reference of all buffers used instead of depending on ttm_bo_put() checking whenever the object is actually idle before releasing it. New workflow: (1) All gem objects needed by a command are added to a virtio_gpu_object_array. (2) All reservation objects will be locked (virtio_gpu_array_lock_resv). (3) virtio_gpu_fence_emit() completes fence initialization. (4) fence gets added to the objects, reservation objects are unlocked (virtio_gpu_array_add_fence, virtio_gpu_array_unlock_resv). (5) virtio command is submitted to the host. (6) The completion callback (virtio_gpu_dequeue_ctrl_func) will drop object references and free virtio_gpu_object_array. v6: rewrite most of the patch.

2019-06-06drm/virtio: Ensure cached capset entries are valid before copying.David Riley
virtio_gpu_get_caps_ioctl could return success with invalid data if a second caller to the function occurred after the entry was created in virtio_gpu_cmd_get_capset but prior to the virtio_gpu_cmd_capset_cb callback being called. This could leak contents of memory as well since the caps_cache allocation is done without zeroing.

We are already doing this for DMA-buf imports and also for amdgpu VM BOs for quite a while now.

Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging. There are also some rcar-du patches which crossover with media tree but all should be acked by Mauro.
