- * Creates a temporary BO containing the pull constant data for the shader
- * stage, and the SURFACE_STATE struct that points at it.
- *
- * Pull constants are GLSL uniforms (and other constant data) beyond what we
- * could fit as push constants, or that have variable-index array access
- * (which is easiest to support using pull constants, and avoids filling
- * register space with mostly-unused data).
- *
- * Compare this path to brw_curbe.c for gen4/5 push constants, and
- * gen6_vs_state.c for gen6+ push constants.
