* mesa/sso: Implement ValidateProgramPipelineGregory Hainaut2014-03-251-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implementation note: I don't use context for ralloc (don't know how). The check on PROGRAM_SEPARABLE flags is also done when the pipeline isn't bound. It doesn't make any sense in a DSA style API. Maybe we could replace _mesa_validate_program by _mesa_validate_program_pipeline. For example we could recreate a dummy pipeline object. However the new function checks also the TEXTURE_IMAGE_UNIT number not sure of the impact. V2: Fix memory leak with ralloc_strdup Formatting improvement V3 (idr): * Actually fix the leak of the InfoLog. :) * Directly generate logs in to gl_pipeline_object::InfoLog via ralloc_asprintf isntead of using a temporary buffer. * Split out from previous uber patch. * Change spec references to include section numbers, etc. * Fix a bug in checking that a different program isn't active in a stage between two stages that have the same program. Specifically, if (pipe->CurrentVertexProgram->Name == pipe->CurrentGeometryProgram->Name && pipe->CurrentGeometryProgram->Name != pipe->CurrentVertexProgram->Name) should have been if (pipe->CurrentVertexProgram->Name == pipe->CurrentFragmentProgram->Name && pipe->CurrentGeometryProgram->Name != pipe->CurrentVertexProgram->Name) v4 (idr): Rework to use CurrentProgram array in loops.

* mesa/sso: Add pipeline container/stateGregory Hainaut2014-02-211-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | V1: * Extend gl_shader_state as pipeline object state * Add a new container gl_pipeline_shader_state that contains binding point of the previous object * Update mesa init/free shader state due to the extension of the attibute * Add an init/free pipeline function for the context V2: * Rename gl_shader_state to gl_pipeline_object * Rename Pipeline.PipelineObj to Pipeline.Current * Formatting improvement V3 (idr): * Split out from previous uber patch. * Remove '#if 0' debug printfs. V4 (idr): * Fix some errors in comments. Suggested by Jordan. Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
* mesa/sso: Add extension entry points for GL_ARB_separate_shader_objectsGregory Hainaut2014-02-211-0/+70
Nothings implemented yet but glProgramUniform* which are mostly a copy/paste of the older function glUniform* I create dedicated pipelineobj.[ch] file that will contains function related to the "new" pipeline container object. V2: formatting improvement V3: * indentation fix * Update copyright * Add a comment on ProgramParameteri already present in another extension * Remove TODO, will be readded on correct patch V4 (idr): * Fix dispatch_sanity unit test * Make extension string available in core profiles (instead of just compatibility). * Trivial reformating Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
