[Spice-devel] [PATCH v3 x11spice 1/5] Add the upstream xf86-video-dummy as of November 25, 2018.

>
> This gives x11spice access to a modern virtual/offscreen
> frame buffer driver for the Xorg X server. We will then
> make slight revisions to make it more suitable for use with Spice.
>
> The overall result should be a more functional stack,
> as compared to the existing xf86-video-qxl driver, as we gain
> a wide range of Mesa features for free. It also simplifies
> the overall process.
>
> This is from https://gitlab.freedesktop.org/xorg/driver/xf86-video-dummy
> as of 850c0516.

> Signed-off-by: Jeremy White <jwhite at codeweavers.com>
Acked-by: Frediano Ziglio <fziglio at redhat.com>

> v2: Provide a specific URL for reference to the upstream xorg driver.
> v3: Unchanged
