Description Sven Arvidsson 2011-06-22 05:31:18 UTC
21972c85ea734dbfcf69629c6b0b940efb42d4ba introduced a regression in the game ETQW:

Failed to allocate :
   size      : -1220046506 bytes
   alignment : 512 bytes
EE r600_texture.c:634 r600_texture_get_transfer - failed to create temporary texture to hold untiled copy

I can provide a backtrace later if necessary.

Comment 1 Michel Dänzer 2011-06-22 07:33:09 UTC
Should be fixed with commit eb2c9b5814f7c6a5b37bc9063b1593095ea4f620 ('r600g: Fix use of uninitialized local variable extra_size.'), thanks for the report.
Comment 2 Andre Maasikas 2011-06-22 08:19:37 UTC
hmm, from reading the patch I would have assumed that this:
+ extra_size = align(extra_size + (nblocksx * nblocksy * 1), base_align);
should have been
+ extra_size = align(size + (nblocksx * nblocksy * 1), base_align);
or smth like this, however i'm not sure about the logic/layout when
mipmap levels are involved(can they be in depth textures?)
 - then extra_size would include and be added only to last level

Arrg, please ignore last comment (seems I fail to read code far too often)
