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:
