X11 Prime renderoffload is another unsolved problem with nouveau depth 30.
Currently we get swapped red-blue with intel + nvidia. We could extend the
buffer creation code to convert nouveau's rgba format into the bgra format
wanted by intel or amd display gpu's during the blitImage call for
converting the tiled renderbuffer to the linear buffer, like i try for the
wayland+egl case. But we'd need to know what the display gpu wants. Haven't
looked into that.
FWIW the NVIDIA hardware is perfectly happy to render into BGR10_A2.
Just can't display it.

Yes, but due to one of your earlier depth 30 commits we only expose
formats with PIPE_BIND_DISPLAY_TARGET, so that ability is hidden from
driver independent code like the EGL platform code, GLX etc. to prevent
exposing formats that the hw can't display.
