* compiler: Add SYSTEM_VALUE_IS_INDEXED_DRAW and instrinsicsAntia Puentes2018-05-021-0/+7
| | | | | | | | | This VS system value contains if the draw command used to start the rendering was an indexed draw command or a non-indexed one (~0/0 respectively). Useful to calculate the gl_BaseVertex as: (SYSTEM_VALUE_IS_INDEXED_DRAW & SYSTEM_VALUE_FIRST_VERTEX). Reviewed-by: Jason Ekstrand <[email protected]>
* compiler: Add SYSTEM_VALUE_FIRST_VERTEX and instrinsicsAntia Puentes2018-04-191-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This VS system value will contain the value passed as <basevertex> for indexed draw calls or the value passed as <first> for non-indexed draw calls. It can be used to calculate the gl_VertexID as SYSTEM_VALUE_VERTEX_ID_ZERO_BASE plus SYSTEM_VALUE_FIRST_VERTEX. From the OpenGL 4.6 spec, 10.4 "Drawing Commands Using Vertex Arrays": - Page 352: "The index of any element transferred to the GL by DrawArraysOneInstance is referred to as its vertex ID, and may be read by a vertex shader as gl_VertexID. The vertex ID of the ith element transferred is first + i." - Page 355: "The index of any element transferred to the GL by DrawElementsOneInstance is referred to as its vertex ID, and may be read by a vertex shader as gl_VertexID. The vertex ID of the ith element transferred is the sum of basevertex and the value stored in the currently bound element array buffer at offset indices + i." Currently the gl_VertexID calculation uses SYSTEM_VALUE_BASE_VERTEX but this will have to change when the value of gl_BaseVertex is fixed. Currently its value is broken for non-indexed draw calls because it must be zero but we are setting it to <first>. v2: use SYSTEM_VALUE_FIRST_VERTEX as name for the value, instead of SYSTEM_VALUE_BASE_VERTEX_ID (Kenneth). v3 (idr): Rebase on Rob Clark converting nir_intrinsics.h to be generated.

* mesa: Put materials at the end of the generic block.Mathias Fröhlich2018-02-011-1/+6
| | | | | | | | | | | | | | | | | | | The materials are now moved to the end of the generic attributes block to the range 4-15. Before, the way the position and generic 0 attribute is handled was dependent on the presence and kind of the currently attached vertex program. With this change the way the position attribute and the generic 0 attribute is treated only depends on the enabled flag of those two arrays. This will later help to untangle the update dependencies between enabled arrays and shader inputs. v2: s,VERT_ATTRIB_MAT_OFFSET,VERT_ATTRIB_MAT0,g Signed-off-by: Mathias Fröhlich <[email protected]> Reviewed-by: Brian Paul <[email protected]>

* nir: Move vc4's alpha test lowering to core NIR.Eric Anholt2017-10-101-0/+17
| | | | | | | | | | | | | I've been doing this inside of vc4, but vc5 wants it as well and it may be useful for other drivers (Intel has a related path for pre-gen6 with MRT, and freedreno had a TGSI path for it at one point). This required defining a common enum for the standard comparison functions, but other lowering passes are likely to also want that enum. v2: Add to meson.build as well.

| | | | | | | | | | | | | | | | | Likewise, rename the enum type to glsl_interp_mode. Beyond the GLSL front-end, talking about "interpolation modes" seems more natural than "interpolation qualifiers" - in the IR, we're removed from how exactly the source language specifies how to interpolate an input. Also, SPIR-V calls these "decorations" rather than "qualifiers".

* glsl: keep track of ssbo variable being accessed, add access paramsIlia Mirkin2016-01-291-0/+10
| | | | | | | | | | | | | | | | | | | | Currently any access params (coherent/volatile/restrict) are being lost when lowering to the ssbo load/store intrinsics. Keep track of the variable being used, and bake its access params in as the last arg of the load/store intrinsics. If the variable is accessed via an instance block, then 'variable' points to the instance block variable and not the field inside the instance block that we are accessing. In order to check access parameters for the field itself we need to detect this case and keep track of the corresponding field struct so we can extract the specific field access information from there instead.
