To:mesa-dev@lists.freedesktop.org From:Brian Paul Subject:[Mesa-dev] [PATCH] softpipe: set max cube texture size to 4Kx4K Date:Sun, 18 Mar 2012 10:49:00 -0600
 

The max size was 16Kx16K so a 4 byte/pixel, six-sided cube would require
6 GBytes of memory. If mipmapped, 8 GB. Reduce the max size to 4K to
make the total size more reasonable.

Fixes a crash with the new piglit max-texture-size test.
