[Nouveau] [NV50] application to confirm texture layout

[Maarten Maathuis]

Here is an app to test the texture layout.

No message means it's ok. Otherwise it spews a lot of errors.

You have to manually set the TILE_HEIGHT, TILE_WIDTH and TILING_PARAM.

TILE_WIDTH == TILE_PITCH in this case because it's 8bpp data.

Use this list (TILING_PARAM) TILE_WIDTHxTILE_HEIGHT:

(0x00) 32x4
(0x10) 64x8
(0x20) 64x16
(0x30) 64x32
(0x40) 64x64

I'm curious to know if anyone has different layouts.

You may need to sudo run it.

Maarten.
