* glsl: use bitmask of active xfb buffer indicesTimothy Arceri2016-03-311-1/+1
| | | | | | | | | | | | | This allows us to print the correct binding point when not all buffers declared in the shader are bound. For example if we use a single buffer: layout(xfb_buffer=2, offset=0) out vec4 v; We now print '2' when the buffer is not bound rather than '0'. Reviewed-by: Dave Airlie <airlied@redhat.com>

* mesa: Separate transform feedback object initialization from allocation.Kenneth Graunke2013-10-311-0/+3
| | | | | | | | | | | Both Gallium and i965 subclass gl_transform_feedback_object, which requires implementing a custom NewTransformFeedback hook. Creating a helper function to initialize the fields avoids code duplication and divergence.

* mesa: Disallow relinking if a program is used by an active XFB object.Kenneth Graunke2013-09-121-0/+4
| | | | | | | | | | | | | | | | | Paused transform feedback objects may refer to a program other than the current program. If any active objects refer to a program, LinkProgram must reject the request to relink. The code to detect this is ugly since _mesa_HashWalk is awkward to use, but unfortunately we can't use hash_table_foreach since there's no way to get at the underlying struct hash_table (and even then, we'd need to handle locking somehow). Fixes the last subcase of Piglit's new ARB_transform_feedback2 api-errors test. Signed-off-by: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Marek Olšák <marek.olsak@amd.com>

* mesa: refactor _mesa_compute_max_transform_feedback_vertices from i965.Paul Berry2012-12-181-0/+5
| | | | | | | | | | | | | | | | | Previously, the i965 driver contained code to compute the maximum number of vertices that could be written without overflowing any transform feedback buffers. This code wasn't driver-specific, and for GLES3 support we're going to need to use it in core mesa. So this patch moves the code into a core mesa function, _mesa_compute_max_transform_feedback_vertices().

* mesa: Fix const correctness of API implementation functions.Paul Berry2012-11-121-1/+2
| | | | | | | | | | | | | | This patch changes the use of const in the type signatures of _mesa_ShaderSource() and _mesa_TransformFeedbackVaryings(), to match the type signatures in the GL spec. This avoids warnings when building the code-generated api_exec.c file. Note: previously we avoided the build warnings because these functions were being type-checked against ShaderSourceARB and TransformFeedbackVaryingsEXT; those functions are semantically equivalent, but have fewer const qualifiers in their type signatures.

* mesa: implement DrawTransformFeedback from ARB_transform_feedback2Marek Olšák2011-12-151-3/+3
| | | | | | | | | | | | | | It's like DrawArrays, but the count is taken from a transform feedback object. This removes DrawTransformFeedback from dd_function_table and adds the same function to GLvertexformat (with the function parameters matching GL). The vbo_draw_func callback has a new parameter "struct gl_transform_feedback_object *tfb_vertcount". The rest of the code just validates states and forwards the transform feedback object into vbo_draw_func.
