Here is a patch to add Appstream metainfo XML announcing the hardware
handled by this package.

Including this information in the package will ensure programs mapping
hardware to packages using Appstream information, like the isenkram
package, will know that this package is useful on machines where the
hardware is discovered.

The appstream metadata file can be checked using this command after
package build:

  appstreamcli validate-tree  --no-net --explain debian/xserver-xorg-video-qxl

For some reason, the install rules in Makefile.am did not take effect, I
suspect the autorebuild setup in debian/rules, so I added a install rule
in debian/xserver-xorg-video-qxl.install to work around this.  I believe
this can be removed if automake is used during build.

Dear xserver-xorg-video-qxl maintainers,

[Petter Reinholdtsen]

It would be great if this package could join 116 other packages in
Debian and start announcing the hardware it support using AppStream
metadata XML.  Any chance you got time to look at this patch and
perhaps include it in unstable?

I'm trying to get rid of all the hardcoded overrides in the isenkram
package, and xserver-xorg-video-qxl is one of the 48 remaining ones. )

Please send this upstream, see
https://gitlab.freedesktop.org/xorg/driver/xf86-video-qxl

Cheers,
Emilio

It is now sent upstream.
