           Summary: [r300g - RV530] main/mipmap.c:144: do_row: Assertion
                    `comps >= 1' failed
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)

Command line output + backtrace

Using r300g up to 57e71b85020fff33d3e5701d0ef61e9fb84b0af4 the game 0ad crashes
with:
pyrogenesis: main/mipmap.c:144: do_row: Assertion `comps >= 1' failed.

This seems a different problem than bug #27634 and could maybe be a mesa core
problem. Command line output + backtrace is attached.

I suspect this is a problem with compressed textures.

Can you go up the stack trace into fallback_generate_mipmap() and print the
value of texObj->Image[face][baseLevel]->TexFormat ?

With 7567f05199f1ca114cc57e3a11ac101d3707f819 it's still crashing with the same
backtraces of comment #3 and comment #4.

patch for r300g is_format_supported()

Here's a patch for r300g (totally untested) that might help.  If it doesn't,
maybe you could debug further and fix the patch.

I think the softpipe bug is something else.  Could you provide the values of
the vars at the failure point?

OK, with that patch r300g now crashes similar to swrastg.

(gdb) p index
$2 = 1
(gdb) p t->psizoutindex
$3 = -1
(gdb) p t->prevInstWrotePsiz
$4 = 0 '\000'
(gdb) p t->outputMapping[index]

Other vars?

That was with r300g. With swrastg:

Can you do "export ST_DEBUG=mesa,tgsi" and re-run?  That should print the GPU
instructions to stderr.  Please attach that output to the bug report.  Thanks.

I've moved some of the debug code to get more useful info from
"ST_DEBUG=mesa,tgsi".

Can you repeat the test with the latest Mesa code (commit
ce0844b44cb3924323ed1fd2b75cda4dbd0013c7) or later?  Thanks.

Anyway you may also want to try the game yourself from
http://trac.wildfiregames.com/wiki/LatestRelease since it appears it will be a
common open source game when finished.

In the meantime 95bfc8f32571751c5c9ec6d8e84f5e3c28d1b20e has been committed
from Marek Olšák which is a subset of attached "patch for r300g
is_format_supported()", but which appears to also fix the r300g problem.

Yes but the S3TC code appears to be bloody slow, e.g. the TA3D game seems to
load a new texture everytime a new GUI element shows up and during that the
game basically locks up for 5 seconds with 100% CPU load. This is unbearable.

With mesa up to 7c5e2672f050644bcab6902b11d0ff4036603bb3 both r300g and swrast
are still crashing, but now in a different way. Game log + backtrace are
