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