-/* Glossary:
- *
- * URB - uniform resource buffer.  A mid-sized buffer which is
- * partitioned between the fixed function units and used for passing
- * values (vertices, primitives, constants) between them.
- *
- * CURBE - constant URB entry.  An urb region (entry) used to hold
- * constant values which the fixed function units can be instructed to
- * preload into the GRF when spawning a thread.
- *
- * VUE - vertex URB entry.  An urb entry holding a vertex and usually
- * a vertex header.  The header contains control information and
- * things like primitive type, Begin/end flags and clip codes.  
- *
- * PUE - primitive URB entry.  An urb entry produced by the setup (SF)
- * unit holding rasterization and interpolation parameters.
- *
- * GRF - general register file.  One of several register files
- * addressable by programmed threads.  The inputs (r0, payload, curbe,
- * urb) of the thread are preloaded to this area before the thread is
- * spawned.  The registers are individually 8 dwords wide and suitable
- * for general usage.  Registers holding thread input values are not
- * special and may be overwritten.
- *
- * MRF - message register file.  Threads communicate (and terminate)
- * by sending messages.  Message parameters are placed in contiguous
- * MRF registers.  All program output is via these messages.  URB
- * entries are populated by sending a message to the shared URB
- * function containing the new data, together with a control word,
- * often an unmodified copy of R0.
- *
- * R0 - GRF register 0.  Typically holds control information used when
- * sending messages to other threads.
- *
- * EU or GEN4 EU: The name of the programmable subsystem of the
- * i965 hardware.  Threads are executed by the EU, the registers
- * described above are part of the EU architecture.
- *
- * Fixed function units:
- *
- * CS - Command streamer.  Notional first unit, little software
- * interaction.  Holds the URB entries used for constant data, ie the
- * CURBEs.
- *
- * VF/VS - Vertex Fetch / Vertex Shader.  The fixed function part of
- * this unit is responsible for pulling vertices out of vertex buffers
- * in vram and injecting them into the processing pipe as VUEs.  If
- * enabled, it first passes them to a VS thread which is a good place
- * for the driver to implement any active vertex shader.
- *
- * GS - Geometry Shader.  This corresponds to a new DX10 concept.  If
- * enabled, incoming strips etc are passed to GS threads in individual
- * line/triangle/point units.  The GS thread may perform arbitary
- * computation and emit whatever primtives with whatever vertices it
- * chooses.  This makes GS an excellent place to implement GL's
- * unfilled polygon modes, though of course it is capable of much
- * more.  Additionally, GS is used to translate away primitives not
- * handled by latter units, including Quads and Lineloops.
- *
- * CS - Clipper.  Mesa's clipping algorithms are imported to run on
- * this unit.  The fixed function part performs cliptesting against
- * the 6 fixed clipplanes and makes decisions on whether or not the
- * incoming primitive needs to be passed to a thread for clipping.
- * User clip planes are handled via cooperation with the VS thread.
- *
- * SF - Strips Fans or Setup: Triangles are prepared for
- * rasterization.  Interpolation coefficients are calculated.
- * Flatshading and two-side lighting usually performed here.
- *
- * WM - Windower.  Interpolation of vertex attributes performed here.
- * Fragment shader implemented here.  SIMD aspects of EU taken full
- * advantage of, as pixels are processed in blocks of 16.
- *
- * CC - Color Calculator.  No EU threads associated with this unit.
- * Handles blending and (presumably) depth and stencil testing.
