Description Fabio Pedretti 2010-07-28 01:16:48 UTC

I noticed a regression with the game 0ad: it crashes with swrastg and it stucks at game start with r300g. 

Bisecting, with both r300g and swrastg:
# good: [815e79e72c1f4aa849c0ee6103621685b678bc9d] draw: re-order optimization passes depending on LLVM version, 32/64-bit
git bisect good 815e79e72c1f4aa849c0ee6103621685b678bc9d
# bad: [7b7845a076c933e096ac511b4184141ba194449a] glx: Move WaitGL, WaitX, UseXFont to context vtable functions
git bisect bad 7b7845a076c933e096ac511b4184141ba194449a

With ab434f6b7641a64d30725a9ac24929240362d466 it works with swrastg but it stucks with r300g. Trying to bisect in between I get other crashes that are apparently fixed later.

The game works fine here with r300g.

Comment 2 Fabio Pedretti 2010-07-28 02:55:53 UTC

Note: with current mesa git the problem appears only with r300g, not with swrastg. I have a RV530. After starting the game (7732 release, with default config, i.e. no ~/.config/0ad/config/local.cfg file) I get:

TIMER| InitVfs: 53.8333 ms
TIMER| InitScripting: 1.18771 ms
TIMER| CONFIG_Init: 4.14799 ms

and the game blocks.

I don't have an r300 here to test with, could you run it under gdb and Ctrl-C it when it hangs and the type 'bt' to get a backtrace?  Also, did you do 'make clean' first?  Mesa has trouble building cleanly when jumping between revisions.

Make sure you have both the driver and libGL*.so from git properly installed, and please let me know if you still have problems even with latest libGL*.so.

This was fixed with 1f1928db001527c3dcf1d78d6a5d2ef8f519327b .
