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

222 * BRW_NEW_*_PROG_DATA and BRW_NEW_*_PROGRAM are similar, but distinct.
224 * BRW_NEW_*_PROGRAM relates to the gl_shader_program/gl_program structures.
225 * When the currently bound shader program differs from the previous draw
226 * call, these will be flagged. They cover brw->{stage}_program and
227 * ctx->{Stage}Program->_Current.
229 * BRW_NEW_*_PROG_DATA is flagged when the effective shaders change, from a
230 * driver perspective. Even if the same shader is bound at the API level,
231 * we may need to switch between multiple versions of that shader to handle
232 * changes in non-orthagonal state.
234 * Additionally, multiple shader programs may have identical vertex shaders
235 * (for example), or compile down to the same code in the backend. We combine
236 * those into a single program cache entry.
238 * BRW_NEW_*_PROG_DATA occurs when switching program cache entries, which
239 * covers the brw_*_prog_data structures, and brw->*.prog_offset.
