* st/mesa: Optionally override RGB/RGBX dst alpha blend factorsKenneth Graunke2019-01-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel's blending hardware does not properly return 1.0 for destination alpha for RGBX formats; it requires the factors to be overridden to either zero or one. Broadcom vc4 and v3d also could use this override. While overriding these factors is safe in general, Nouveau and Radeon would prefer not to. Their blending hardware already returns correct values for RGB/RGBX formats, and would like to avoid the resulting per-buffer blending and independent blend factors (rgb != a) since it can cause additional overhead. I considered simply handling this in the driver, but it's not as nice. pipe_blend_state doesn't have any format information, so we'd need the hardware blend state to depend on both pipe_blend_state and pipe_framebuffer_state. Furthermore, Intel GPUs don't have a native RGBX_SNORM format, so I avoid exposing one, which makes Gallium fall back to RGBA_SNORM. The pipe_surfaces we get in the driver have an RGBA format, making it impossible to tell that there shouldn't be an alpha channel. One could argue that st not handling it in that case is a bug. To work around this, we'd have to expose RGBX pipe formats, mapped to RGBA hardware formats, and add format swizzling special cases. All doable, but it ends up being more code than I'd like. st_atom_blend already has access to the right information and it's trivial to accomplish there, so we just add a cap bit and do that.

* gallium: Add the ability to query a single pipeline statistics counterKenneth Graunke2019-01-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gallium historically has treated pipeline statistics queries as a single query, PIPE_QUERY_PIPELINE_STATISTICS, which returns a block of 11 values. This was originally patterned after the D3D1x API. Much later, Brian introduced an OpenGL extension that exposed these counters - but it exposes 11 separate queries, each of which returns a single value. Today, st/mesa simply queries all 11 values, and returns a single value. While pipeline statistics counters aren't typically performance critical, this is still not a great fit. A D3D1x->GL translator might request all 11 counters by creating 11 separate GL queries...which Gallium would map to reads of all 11 values each time, resulting in a total 121 counter reads. That's not ideal. This patch adds a new cap, PIPE_CAP_QUERY_PIPELINE_STATISTICS_SINGLE, and corresponding query type PIPE_QUERY_PIPELINE_STATISTICS_SINGLE. When calling create_query(), q->index should be set to one of the PIPE_STAT_QUERY_* enums to select a counter. Unlike the block query, this returns the value in pipe_query_result::u64 (as it's a single value) instead of the pipe_query_data_pipeline_statistics group. We update st/mesa to expose ARB_pipeline_statistics_query if either capability is set, preferring the new SINGLE variant when available. Thanks to Roland, Ilia, and Marek for helping me sort this out. Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Tapani Pälli <[email protected]>
* st/mesa: Make an enum for pipeline statistics query result indices.Kenneth Graunke2019-01-151-0/+17
| | | | | | | | | | | | Gallium handles pipeline statistics queries as a single query (PIPE_QUERY_PIPELINE_STATISTICS) which returns a struct with 11 values. Sometimes it's useful to refer to each of those values individually, rather than as a group. To avoid hardcoding numbers, we define a new enum for each value. Here, the name and enum value correspond to the index in the struct pipe_query_data_pipeline_statistics result.

* winsys/amdgpu: explicitly declare whether buffer_map is permanent or notNicolai Hähnle2018-11-281-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new driver-private transfer flag RADEON_TRANSFER_TEMPORARY that specifies whether the caller will use buffer_unmap or not. The default behavior is set to permanent maps, because that's what drivers do for Gallium buffer maps. This should eliminate the need for hacks in libdrm. Assertions are added to catch when the buffer_unmap calls don't match the (temporary) buffer_map calls. I did my best to update r600 for consistency (r300 needs no changes because it never calls buffer_unmap), even though the radeon winsys ignores the new flag. As an added bonus, this should actually improve the performance of the normal fast path, because we no longer call into libdrm at all after the first map, and there's one less atomic in the winsys itself (there are now no atomics left in the UNSYNCHRONIZED fast path).
