Reduce GL_MAX_TEXTURE_SIZE to avoid memory overflow
I have a GeForce4 MX 440-SE card with 64 MB RAM, and I have the following
problems:
1. When I maximize the windows of Clutter-based apps (quadrapassel,
emerillon...), their contents are disappear, and some other parts of the screen
are corrupted.
2. When I start a new game in extremetuxracer second or third time, some
textures are corrupted.
When it happens, I get the following messages in dmesg several times:
[21415.164810] [drm] nouveau 0000:01:00.0: fail ttm_validate
[21415.164821] [drm] nouveau 0000:01:00.0: validate vram_list
[21415.165831] [drm] nouveau 0000:01:00.0: validate: -12
[21415.878743] nouveau_ratelimit: 4 callbacks suppressed
[21415.878750] [drm] nouveau 0000:01:00.0: PGRAPH - ERROR nsource: DATA_ERROR
nstatus: BAD_ARGUMENT PROTECTION_FAULT
[21415.878763] [drm] nouveau 0000:01:00.0: PGRAPH - ch 2/4 class 0x0089 mthd
0x0304 data 0x02b5b500
I found that these problems can be fixed by reducing MaxTextureLevels value:
- Reducing from 12 to 11 resolves the first problem.
- Reducing to 10 resolves the second problem also.
I attached a patch which makes this change.
