Hi,
I am playing with Wayland this weekend.
Unfortunately, my RV250 is not r300g-compatible.
As a workaround I wanted to build and use swrast-gallium for Wayland (compositor).
Immediately, when I have "dri" in my autogen line like "--with-state-trackers=dri,glx,egl" I get also r300_dri.so (r300g) and EGL/pipe_r300.so auto-built.
My RV250 has problems to use pipe_r300.so (see below). I must confirm that "dri" as state-tracker is required to get run Wayland here (after several builds).
NOTE: After several starts of the compositor, I got Wayland running with a background image (JPG). But this is very weaky.
Building mesa with "--with-state-trackers=glx,egl" (no dri set) results in an unuseable Wayland.
Next problem is I cannot run Wayland with a mesa compiled with --disable-gallium. So Gallium seems to be a must-have as Chia-I Wu confirmed on the wayland-devel ML.
In the end - as a more stable solution - I want to use swrastg_dri.so
- EGL/pipe_swrast.so instead.
The mesa build-system is not recognizing this wish of mine.
Is my workaround idea wrong? If not, is it a good idea to modify mesa-buildsystem to have *only* swrastg_dri.so + EGL/pipe_swrast.so built (NO r300* stuff)?
Thanks in advance.
Kind Regards,

P.S.: The background shows Walter (a friend of mine) in the cathedral/dome of Aachen/Germany.
P.S.S.:
An autogen line looks like this...
./autogen.sh --prefix=/opt/wayland --with-driver=dri --with-dri-driverdir=/opt/wayland/lib/dri --with-dri-drivers=swrast --enable-gallium-swrast --with-state-trackers=dri,glx,egl --disable-glu --disable-glut --disable-glw --enable-egl --enable-gles2
...results in:

This leads to errors when starting the Wayland compositor:

Fact is pipe_r300.so is used:
