What's the current state of the gallium-0.2 branch for Cell?
Building it, I've seen the following :
Making programs for linux-cell
make[2]: Entering directory `/home/jonathan/src/mesa.git/progs/demos'

make[2]: *** [arbfplight] Error 1
brw_create appears to be i965 specific, and removing xmesa_create_i965simple
from src/gallium/winsys/xlib/xm_winsys_aub.c and its call in
src/gallium/winsys/xlib/xm_api.c gets past the above error and on to a somewhat
functional build: glxgears will run for 10-20 seconds before the screen goes
black and the framerate numbers seem to go a bit crazy. e.g.
~/gallium-0.2 $ DISPLAY=:0.0 LD_LIBRARY_PATH=. ./glxgears
318 frames in 5.0 seconds = 63.472 FPS
318 frames in 5.0 seconds = 63.487 FPS
318 frames in 5.0 seconds = 63.570 FPS
309 frames in 5.0 seconds = 61.644 FPS # Screen goes black
324 frames in 5.0 seconds = 64.714 FPS
324 frames in 5.0 seconds = 64.715 FPS
325 frames in 5.0 seconds = 64.855 FPS
96 frames in 17593.7 seconds = 0.005 FPS
1874 frames in 29.0 seconds = 64.617 FPS
388 frames in 6.0 seconds = 64.656 FPS
2519 frames in 39.0 seconds = 64.592 FPS
Also, I'm using a recent fsf gcc-4.4 snapshot and needed to make the following
change :
