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