Hi,
I've been trying to run project xenocide(projectxenocide.com), but at
the start of it there's a ps20 shader which always causes a crash.
Setting "USE_ARB_F_P == 0" in r300_context.c makes the program run.
I'm using current mesa and drm(1.2)
The error I get is:
drmRadeonCmdBuffer: -22 (exiting)

And in dmesg:
[drm:r300_emit_carefully_checked_packet0] *ERROR* Cannot emit more than
64 values at a time (reg=4c00 sz=68)
[drm:r300_do_cp_cmdbuf] *ERROR* r300_emit_packet0 failed

Is 64 values a hardware limit?

Seems that the ps20 shader reach the hardware limit. Does fglrx works
with this ? This might be due to the traduction of the program which isn't
optimal. I guess we can save few more instructions and go from 68 to 64.
Btw coud you try with USE_ARB_F_P == 1 and setting if (1) Dump..
in r300_fragprog.c (at bottom of the file).

fglrx halts even with glxinfo here for some reason (linux 2.6.15.1, xorg 2.6.9)

I've attached the dump with USE_ARB_F_P == 1.
