* glsl: add top level array size and stride to gl_uniform_storageTapani Pälli2015-10-141-10/+22
| | | | | | | | | | | | Patch adds 2 new fields to gl_uniform_storage so that we don't need to calculate these values during runtime shader queries. This is required by upcoming changes to free GLSL IR after linking. Patch moves 3 booleans inside structure so that structure size stays the same after this change.

* glsl: add uniform and program resource support (v2)Dave Airlie2015-07-231-0/+8
| | | | | | | | | | | | | | | | | | | This adds linker support for subroutine uniforms, they have some subtle differences from real uniforms, we also hide them and they are given internal uniform names. This also adds the subroutine locations and subroutine uniforms to the program resource tracking for later use. v1.1: drop is_subroutine_def v2: handle explicit location properly, ARB_explicit_location has a lot of language for subroutine shaders. Calculate a link time the number of compatible subroutines for a uniform, to make program resource easier later.

* mesa: reference built-in uniforms into gl_uniform_storageMartin Peres2015-06-041-0/+5
| | | | | | | | | | | | | | | This change introduces a new field in gl_uniform_storage to explicitely say that a uniform is built-in. In the case where it is, no storage is defined to make it clear that it is read-only from the mesa side. I fixed all the places in the code that made use of the structure that I changed. Any place making a wrong assumption and using the storage straight away will just crash. This patch seems to implement the path of least resistance towards listing built-in uniforms in GL_ACTIVE_UNIFORM (and other APIs).

* glsl: Add infrastructure for "hidden" uniforms.Kenneth Graunke2014-11-061-0/+6
| | | | | | | | | | | | | | | In the compiler, we'd like to generate implicit uniforms for internal use. These should not be visible via the GL uniform introspection API. To support that, we add a new ir_variable::how_declared value of ir_var_hidden, and plumb that through to gl_uniform_storage. v2 (idr): Fix some memory management issues in move_hidden_uniforms_to_end. The comment block on the function has more details. Signed-off-by: Kenneth Graunke <kenneth@whitecape.org> Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>
* glsl: Delete unused gl_uniform_driver_format enum values.Kenneth Graunke2014-10-211-11/+0
| | | | | | | | | | | | | | A while back, Matt made the uniform upload functions simply upload ctx->Const.UniformBooleanTrue for boolean values instead of 0/1, which removed the need to convert it later. We also set UniformBooleanTrue to 1.0f for drivers which want to treat booleans as 0.0/1.0f. Nothing ever sets these, so they are dead.

| | | | | | | | | | | | | | | | | Patch adds a remap table for uniforms that is used to provide a mapping from application specified uniform location to actual location in the UniformStorage. Existing UniformLocationBaseScale usage is removed as table can be used to set sequential values for array uniform elements. This mapping helps to implement GL_ARB_explicit_uniform_location so that uniforms locations can be reorganized and handled in a more easy manner. v2: small fixes + rename parameters for merge and split functions (Ian) improve documentation, remove old check for location bounds (Eric) Signed-off-by: Tapani Pälli <tapani.palli@intel.com> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com> Reviewed-by: Eric Anholt <eric@anholt.net>

* mesa: Clean up nomenclature for pipeline stages.Paul Berry2014-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we had an enum called gl_shader_type which represented pipeline stages in the order they occur in the pipeline (i.e. MESA_SHADER_VERTEX=0, MESA_SHADER_GEOMETRY=1, etc), and several inconsistently named functions for converting between it and other representations: - _mesa_shader_type_to_string: gl_shader_type -> string - _mesa_shader_type_to_index: GLenum (GL_*_SHADER) -> gl_shader_type - _mesa_program_target_to_index: GLenum (GL_*_PROGRAM) -> gl_shader_type - _mesa_shader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string This patch tries to clean things up so that we use more consistent terminology: the enum is now called gl_shader_stage (to emphasize that it is in the order of pipeline stages), and the conversion functions are: - _mesa_shader_stage_to_string: gl_shader_stage -> string - _mesa_shader_enum_to_shader_stage: GLenum (GL_*_SHADER) -> gl_shader_stage - _mesa_program_enum_to_shader_stage: GLenum (GL_*_PROGRAM) -> gl_shader_stage - _mesa_progshader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string In addition, MESA_SHADER_TYPES has been renamed to MESA_SHADER_STAGES, for consistency with the new name for the enum.

* mesa: fix GLSL program objects with more than 16 samplers combinedMarek Olšák2013-05-281-9/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | The problem is the sampler units are allocated from the same pool for all shader stages, so if a vertex shader uses 12 samplers (0..11), the fragment shader samplers start at index 12, leaving only 4 sampler units for the fragment shader. The main cause is probably the fact that samplers (texture unit -> sampler unit mapping, etc.) are tracked globally for an entire program object. This commit adapts the GLSL linker and core Mesa such that the sampler units are assigned to sampler uniforms for each shader stage separately (if a sampler uniform is used in all shader stages, it may occupy a different sampler unit in each, and vice versa, an i-th sampler unit may refer to a different sampler uniform in each shader stage), and the sampler-specific variables are moved from gl_shader_program to gl_shader. This doesn't require any driver changes, and it fixes piglit/max-samplers for gallium and classic swrast. It also works with any number of shader stages. v2: - converted tabs to spaces - added an assertion to _mesa_get_sampler_uniform_value Reviewed-by: Ian Romanick <ian.d.romanick@intel.com> Reviewed-by: Eric Anholt <eric@anholt.net>
