[Mesa-dev] [PATCH v2 0/9] radeonsi, radv: fix cube map coordinate derivatives

[Nicolai Hähnle]

Hi all,

once more without the change to the offset, and with a small fix on
patch #5: while munging radv and radeonsi versions of prepare_cube_coords
together, I accidentally went back to touching all four coordinates.
This is fixed now.

With Bas' testing on radv and more thorough piglit/cts testing on
radeonsi, this looks correct now. I admit I still don't understand
understand the 0.5 vs. 1.5 offset issue, but (a) we now stick to the
magic 1.5 that was used before, (b) the tests look good, and (c) I'd
like to land this for 17.0, so...

Thanks,
Nicolai
