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

+/* 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.
