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

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

463 * From the OpenGL 3.0 spec, table 6.44 (Transform Feedback State), the
464 * minimum value of MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS is 64.
466 * On Gen6, the size of transform feedback data is limited not by the number
467 * of components but by the number of binding table entries we set aside. We
468 * use one binding table entry for a float, one entry for a vector, and one
469 * entry per matrix column. Since the only way we can communicate our

472 * worst case, in which all the varyings are floats, so we use up one binding
473 * table entry per component. Therefore we need to set aside at least 64
474 * binding table entries for use by transform feedback.
476 * Note: since we don't currently pack varyings, it is currently impossible
477 * for the client to actually use up all of these binding table entries--if
