gallium/tgsi: start adding hw atomics (v3.2)
This adds support for a hw atomic counters to TGSI. A new register file for storing atomic counters is added, along with a new atomic counter semantic, along with docs for both. v2: drop semantic, move hw counter to backend, Ilia pointed out SSO would have busted my plan, and he was right. v3: drop BUFFER decls. (Marek) v3.1: minor fixups for whitespace, set ureg error if we overflow the hw atomic limits. (nha) v3.2: fix some docs inconsistencies (Ilia) Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Nicolai Hähnle <[email protected]> Tested-By: Gert Wollny <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
