* gallium: add CAPs to support HW atomic counters. (v3)Dave Airlie2017-11-101-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | This looks like an evergreen specific feature, but with atomic counters AMD have hw specific counters they use instead of operating on buffers directly. These are separate to the buffer atomics, so require different limits and code paths. I've left the CAP for atomic type extensible in case someone else has a variant on this sort of thing (freedreno maybe?) and needs to change it. This adds all the CAPs required to add support for those atomic counters, along with a related CAP for limiting the number of output resources. I'd like to land this and the st patch then I can start to upstream the evergreen support for these and other GL4.x features. v2: drop the ATOMIC_COUNTER_MODE cap, just use the return from the HW counters. If 0 we use the current mode. v3: fix some rebase errors (Gert Wollny) Reviewed-by: Nicolai Hähnle <[email protected]> Reviewed-by: Marek Olšák <[email protected]> Tested-By: Gert Wollny <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
* gallium: add PIPE_FLUSH_{TOP,BOTTOM}_OF_PIPE bitsNicolai Hähnle2017-11-091-0/+14
| | | | | | | | | | | | | | | | These bits are intended to be used by the ddebug hang detection and are named in analogy to the Vulkan stage bits (and the corresponding Radeon pipeline event). Hang detection needs fences on the granularity of individual commands, which nothing else really covers. The closest alternative would have been PIPE_QUERY_GPU_FINISHED, but (a) queries are a per-context object and we really want a per-screen object, (b) queries don't offer a wait with timeout, and (c) in any case, PIPE_QUERY_GPU_FINISHED is meant to imply that GPU caches are flushed, which the new bits explicitly aren't.

| | | | | | | | | | | | | | | | Because vc4 can control the order that tiles are rasterized in, we can use it to implement overlapping blits using normal drawing and GL_ARB_texture_barrier, as long as we can tell the kernel what order to render the tiles in. This commit introduces the core gallium support, vc4 changes will follow. v2: Fix on the simulator. v3: Add the cap (disabled) to other drivers, add rst docs for the cap. v4: Rebase on PIPE_CAP_TGSI_ANY_REG_AS_ADDRESS v5: Drop vc4 changes from this commit, for clarity.

* tgsi: clarify the semantics of DFRACEXPNicolai Hähnle2017-09-291-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The status quo is quite the mess: 1. tgsi_exec will do a per-channel computation, and store the dst[0] result (significand) correctly for each channel. The dst[1] result (exponent) will be written to the first bit set in the writemask. So per-component calculation only works partially. 2. r600 will only do a single computation. It will replicate the exponent but not the significand. 3. The docs pretend that there's per-component calculation, but even get dst[0] and dst[1] confused. 4. Luckily, st_glsl_to_tgsi only ever emits single-component instructions, and kind-of assumes that everything is replicated, generating this for the dvec4 case: DFRACEXP TEMP[0].xy, TEMP[1].x, CONST[0][0].xyxy DFRACEXP TEMP[0].zw, TEMP[1].y, CONST[0][0].zwzw DFRACEXP TEMP[2].xy, TEMP[1].z, CONST[0][1].xyxy DFRACEXP TEMP[2].zw, TEMP[1].w, CONST[0][1].zwzw Settle on the simplest behavior, which is single-component calculation with replication, document it, and adjust tgsi_exec and r600.
