Nice, looks totally valid to me.

Variable num_relocs is not effectively used, so delete it. Having two
labels seems somewhat redundant; the 'out_free_release' can be removed,
leaving 'out_free_bos'.
drivers/gpu/drm/qxl/qxl_ioctl.c:148:14: warning: variable 'num_relocs' set but
not used.

We do not want to stop a stream associated with gl_draw as a result
of timeout because we may not get another opportunity to create a
new stream if the current one gets stopped. However, when the
stream does get stopped for other reasons, we need to clear the
gl_draw_stream pointer associated with
For non-gl/remote clients, if there is no stream associated with
the DisplayChannel, then we create a new stream. Otherwise, we
just update the current stream's timestamp.
v2: (suggestions and fixups from Frediano)
- Moved the gl_draw_stream object from DCC to DC
- Moved the stream initialization
We need to determine if the client is new enough to support multiple
codecs -- which might include any of the Gstreamer based ones.
v2: (suggestions and fixups from Frediano)
- Add is_gl_client() method to DisplayChannelClient instead of a
dcc_is_gl_client() function.
- Avoid the usage of XXX_CA
This patch adds a new function to enable the creation of Gst memory with
the dmabuf fd as the source by using a dmabuf allocator. And, it also
adds a mechanism to register and invoke any callbacks once the Gst memory
object is no longer used by the pipeline.
This patch also ensures that the source
For remote (or non-gl) clients, if a valid gl_draw stream exists,
then we first extract the dmabuf fd associated with the scanout and
share it with the encoder along with other key parameters such as
stride, width and height. Once the encoder finishes creating an
encoded buffer (using the dmabuf fd
For clients that cannot accept a dmabuf fd directly (such as those
running on a remote system), this patch series provides a way for
the Spice server to stream the gl/dmabuf data/buffer instead. This
is mostly done by enabling the creation of Gst memory using a dmabuf
fd as the source. This ability
