[Mesa-dev] [PATCH v3 00/12] nvc0: ARB_compute_shader for Kepler/Maxwell

[Samuel Pitoiset]

Hi,

This series adds support for ARB_compute_shader on GK104 and GM107+, except on
GK110 where one test miserably fail (related to texelFetch) for really weird
reasons. Anyway, this is not going to break anything because NVF0_COMPUTE is
still required for using compute on GK110. I will have a deeper look at this
fail later.

Almost all dEQP compute tests pass with a very good ratio. As usual, the list
of fails is described below. About piglit, only two tests fail but this is
related to images support.

I don't update GL3.txt in this series because compute shaders are not really
useful without images support.

ARB_shader_image_load_store and ARB_shader_image_size are in work in progress
and should be ready in a couple of weeks.

Please review,
Thanks!
