* gallium: Add PIPE_SHADER_CAP_FP16Jan Vesely2017-09-181-0/+2
| | | | | | | | | Denotes native half precision float operations capability v2: PIPE_CAP_HALFS -> PIPE_SHADER_CAP_FP16 fix indentation Signed-off-by: Jan Vesely <[email protected]> Reviewed-by: Nicolai Hähnle <[email protected]>
* gallium: add PIPE_QUERY_OCCLUSION_PREDICATE_CONSERVATIVENicolai Hähnle2017-09-181-0/+6
| | | | | | | | | | | | | | | | | To be able to properly distinguish between GL_ANY_SAMPLES_PASSED and GL_ANY_SAMPLES_PASSED_CONSERVATIVE. This patch goes through all drivers, having them treat the two query types identically, except: 1. radeon incorrectly enabled conservative mode on PIPE_QUERY_OCCLUSION_PREDICATE. We now do it correctly, only on PIPE_QUERY_OCCLUSION_PREDICATE_CONSERVATIVE. 2. st/mesa uses the new query type. Fixes dEQP-GLES31.functional.fbo.no_attachments.* Reviewed-by: Marek Olšák <[email protected]>

For the TXQS opcode and TGSI_SEMANTIC_SAMPLEID, clarify return value and type. For the TGSI_SEMANTIC_SAMPLEPOS system value, clarify the range of positions returned. v2: use 'undef' for unused vector components. Use (0.5, 0.5, undef, undef) for sample pos when MSAA not applicable. v3: Add note that OPCODE_SAMPLE_INFO, OPCODE_SAMPLE_POS are not used yet and the information is subject to change.

| | | | | | | | | | | | | | pipe_draw_info::indexed is replaced with index_size. index_size == 0 means non-indexed. Instead of pipe_index_buffer::offset, pipe_draw_info::start is used. For indexed indirect draws, pipe_draw_info::start is added to the indirect start. This is the only case when "start" affects indirect draws. pipe_draw_info::index is a union. Use either index::resource or index::user depending on the value of pipe_draw_info::has_user_indices. v2: fixes for nine, svga
