dma-buf: drop the _rcu postfix on function names v3

2021-06-06T09:19:51+00:00

The functions can be called both in _rcu context as well
as while holding the lock.

v2: add some kerneldoc as suggested by Daniel
v3: fix indentation

drm/virtio: advertise features to userspace

2020-09-29T09:23:57+00:00

New api changes are now available to userspace. Also, the
comparison to true is redundant, so remove it.

drm/virtio: implement blob resources: report blob mem to userspace

2020-09-29T09:23:49+00:00

The stride field has never been used, so repurpose it to be
"blob_mem". This way, userspace can know the memory properties
of the blob if it's passed between userspace processes and
no suitable userspace API exists to transmit that knowledge.

drm/virtio: implement blob resources: fix stride discrepancy

2020-09-29T09:23:47+00:00

The old transfer ioctls may work on blob resources, and there is no
TRANSFER_BLOB hypercall now for simplicity.

The guest may have a image view on the blob resources such that the
stride is not equal to width * bytes_per_pixel.

For host-only blobs, we can repurpose the transfer ioctls to synchronize
caches as well.  For guest-only blobs, these operations are undefined
for now so leave them out.

Also, with seamless Wayland integration between guest/host looking
increasingly attractive, it also makes sense to keep track of
one value for stride.

drm/virtio: fix missing dma_fence_put() in virtio_gpu_execbuffer_ioctl()

2020-08-07T11:55:54+00:00

We should put the reference count of the fence after calling
virtio_gpu_cmd_submit(). So add the missing dma_fence_put().
