-/* 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 spawining 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 contigous

- * 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 descisions 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.

+/* 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 spawining 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 contigous
+ * 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 descisions 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.
