* gallium: add PIPE_CAP_MAX_VARYINGSKarol Herbst2019-02-071-0/+4
| | | | | | | | | | | | | | | | | Some NVIDIA hardware can accept 128 fragment shader input components, but only have up to 124 varying-interpolated input components. We add a new cap to express this cleanly. For most drivers, this will have the same value as PIPE_SHADER_CAP_MAX_INPUTS for the fragment shader.

| | | | | | | | | Iris would like to use compact arrays for tesslevels and clip/cull distances. radeonsi will likely want to switch to these at some point, since it'll be necessary for GL_ARB_gl_spirv support, but it's not ready for them just yet. Reviewed-by: Timothy Arceri <[email protected]>

* 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/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]>

| | | | | | | | | | | | | Some hardware can do PIPE_TEX_WRAP_MIRROR_REPEAT but not PIPE_TEX_WRAP_MIRROR_CLAMP and PIPE_TEX_WRAP_MIRROR_CLAMP_TO_BORDER.

| | | | | | | | | | | | | | | | 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).
