Hello,
No idea if this problem has been raised, but I had a problem running the demos
@ http://www.garagegames.com on a radeon ddr 32.
It seems to crash (lock hardware, the new IRQ code gives EBUSY, but the exit()
isn't clean) rendering triangle fan elts :-
xc/extras/Mesa/src/tnl_dd/t_dd_dmatmp2.h for (j = start + 1 ; j + 1 < count; j += nr - 1 ) { nr = MIN2( currentsz, count - j + 1 ); TAG(emit_elts)( ctx, elts+start, 1 ); TAG(emit_elts)( ctx, elts+j, nr - 1 ); NEW_PRIMITIVE(); currentsz = dmasz;
iff the first vertex is emitted by itself at the end of a CmdBuf.
Here's a patch that prevents Think Tanks (and possibly other heavy users of triangle fans) from crashing on Radeon hardware. There seem to be some other texture related problems, but I haven't had a chance to delve into that. This should also fix similar problems on R200 hardware, but I haven't tested that out yet either.
Basically, I just in-lined emit_elts and did some minor clean-up. One problem that I have with emit_elts is that it seems to assume that the number of elts to emit is *always* a multiple of 2. Clearly this may not always be the case.
I just tried it out on a 64MB R200 (my R100 card is 32MB), and the texturing problems went away. My current thinking, therefore, is that there's a texture management problem lurking in there. I'll try to take a look into it. Could this be the same as the (fixed) problem with the i830 driver?
