  41 /* Glossary:
  42  *
  43  * URB - uniform resource buffer.  A mid-sized buffer which is
  44  * partitioned between the fixed function units and used for passing
  45  * values (vertices, primitives, constants) between them.
  46  *
  47  * CURBE - constant URB entry.  An urb region (entry) used to hold
  48  * constant values which the fixed function units can be instructed to
  49  * preload into the GRF when spawining a thread.
  50  *
  51  * VUE - vertex URB entry.  An urb entry holding a vertex and usually
  52  * a vertex header.  The header contains control information and
  53  * things like primitive type, Begin/end flags and clip codes.
  54  *
  55  * PUE - primitive URB entry.  An urb entry produced by the setup (SF)
  56  * unit holding rasterization and interpolation parameters.
  57  *
  58  * GRF - general register file.  One of several register files
  59  * addressable by programmed threads.  The inputs (r0, payload, curbe,
  60  * urb) of the thread are preloaded to this area before the thread is
  61  * spawned.  The registers are individually 8 dwords wide and suitable
  62  * for general usage.  Registers holding thread input values are not
  63  * special and may be overwritten.
  64  *
  65  * MRF - message register file.  Threads communicate (and terminate)
  66  * by sending messages.  Message parameters are placed in contigous
  67  * MRF registers.  All program output is via these messages.  URB
  68  * entries are populated by sending a message to the shared URB
  69  * function containing the new data, together with a control word,
  70  * often an unmodified copy of R0.
  71  *
  72  * R0 - GRF register 0.  Typically holds control information used when
  73  * sending messages to other threads.
  74  *
  75  * EU or GEN4 EU: The name of the programmable subsystem of the
  76  * i965 hardware.  Threads are executed by the EU, the registers
  77  * described above are part of the EU architecture.
  78  *
  79  * Fixed function units:
  80  *
  81  * CS - Command streamer.  Notional first unit, little software
  82  * interaction.  Holds the URB entries used for constant data, ie the
  83  * CURBEs.
  84  *
  85  * VF/VS - Vertex Fetch / Vertex Shader.  The fixed function part of
  86  * this unit is responsible for pulling vertices out of vertex buffers
  87  * in vram and injecting them into the processing pipe as VUEs.  If
  88  * enabled, it first passes them to a VS thread which is a good place
  89  * for the driver to implement any active vertex shader.
  90  *
  91  * GS - Geometry Shader.  This corresponds to a new DX10 concept.  If
  92  * enabled, incoming strips etc are passed to GS threads in individual
  93  * line/triangle/point units.  The GS thread may perform arbitary
  94  * computation and emit whatever primtives with whatever vertices it
  95  * chooses.  This makes GS an excellent place to implement GL's
  96  * unfilled polygon modes, though of course it is capable of much
  97  * more.  Additionally, GS is used to translate away primitives not
  98  * handled by latter units, including Quads and Lineloops.
  99  *
 100  * CS - Clipper.  Mesa's clipping algorithms are imported to run on
 101  * this unit.  The fixed function part performs cliptesting against
 102  * the 6 fixed clipplanes and makes descisions on whether or not the
 103  * incoming primitive needs to be passed to a thread for clipping.
 104  * User clip planes are handled via cooperation with the VS thread.
 105  *
 106  * SF - Strips Fans or Setup: Triangles are prepared for
 107  * rasterization.  Interpolation coefficients are calculated.
 108  * Flatshading and two-side lighting usually performed here.
 109  *
 110  * WM - Windower.  Interpolation of vertex attributes performed here.
 111  * Fragment shader implemented here.  SIMD aspects of EU taken full
 112  * advantage of, as pixels are processed in blocks of 16.
 113  *
 114  * CC - Color Calculator.  No EU threads associated with this unit.
 115  * Handles blending and (presumably) depth and stencil testing.
