I reworded parts of the comments, and simplified the patch against the shader to correct the piglit failures and taking into account that a shader can not set an offset for the array index at all.
Apart from the dEQP tests I've run ./piglit run gpu -t texture with no changes. (I always got hangs with "./piglit run gpu -x atomicity", with or without these patches, some image_store_load tests seem to behave badly) I'm still thinking about how relevant the TRUNC versus default rounding mode is and what is actually the more correct approach for point sampling. That's also why I think that it is better to keep the patches apart, to better be able to biscet possible issues. best, Gert Gert Wollny (2): r600: correct texture offset for array index lookup r600: set rounding mode for texture array layer selection src/gallium/drivers/r600/evergreen_state.c | 22 ++++++++++++++++++++++ src/gallium/drivers/r600/r600_shader.c | 18 +++++++++++++++++- 2 files changed, 39 insertions(+), 1 deletion(-) -- 2.16.4 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
