Bug description:
[ Impact ]
Xilinx Mali support was originally written for GNOME 42 but it has
bitrotted since then. We need to apply a few fixes to get it working
again in GNOME 46 (Ubuntu 24.04 LTS) and later:
* https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4019 or
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4021
* https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4036
[ Test Plan ]
1. Log into an Ubuntu (GNOME + Wayland) session on Xilinx hardware.
2. Verify you can log in, there are no obvious rendering failures and that it
really is a Wayland session (environment XDG_SESSION_TYPE=wayland and
WAYLAND_DISPLAY=wayland-0).
[ Where problems could occur ]
The Mutter/GNOME startup procedure had to be modified for this fix as well as
some texture format parameters. So there is a small risk to:
(a) The ability of any machine to log into a Wayland session; and
(b) Rendering correctness once logged in.
