[Mesa-dev] [PATCH 10/10] r600g: add initial cube map array support
Dave Airlie

Tue Nov 6 14:16:05 PST 2012
This contains the evergreen support.
Support is possible on rv670 upwards and the code in here
should work, but it doesn't and I haven't debugged it to
figure out why.
Beyond just adding support for the cube map array sampling,
r600 resinfo isn't conformant with the GL specification,
which states the number of layers should be returned for
the textureSize, so we have to track in an external
constant buffer the layers for each sampler if we need
them in the shader.
