[PATCH] drm/virtio: fix mmap page attributes
virtio-gpu uses cached mappings. shmem helpers use writecombine though. So roll our own mmap function, wrapping drm_gem_shmem_mmap(), to tweak vm_page_prot accordingly.

[PATCH v7 14/18] drm/virtio: switch from ttm to gem shmem helpers
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:

[PATCH v2] drm/virtio: rework batching
Drop the virtio_gpu_{disable,enable}_notify(). Add a new virtio_gpu_notify() call instead, which must be called whenever the driver wants make sure the host is notified needed. Drop notification from command submission. Add virtio_gpu_notify() calls everywhere instead. This results in more batching because we now notify only once for a series of commands. We already had that for page flips,

[PATCH v2 4/4] drm/virtio: move virtio_gpu_mem_entry initialization to new function
Introduce new virtio_gpu_object_shmem_init() helper function which will create the virtio_gpu_mem_entry array, containing the backing storage information for the host. For the most path this just moves code from virtio_gpu_object_attach().
