A mid-sized buffer which is 47 * partitioned between the fixed function units and used for passing 48 * values (vertices, primitives, constants) between them. 49 * 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. 53 * 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. 57 * 58 * PUE - primitive URB entry. An urb entry produced by the setup (SF) 59 * unit holding rasterization and interpolation parameters. 60 * 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. 67 * 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. 74 * 75 * R0 - GRF register 0. Typically holds control information used when 76 * sending messages to other threads. 77 * 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. 81 * 82 * Fixed function units: 83 * 84 * CS - Command streamer. Notional first unit, little software 85 * interaction. Holds the URB entries used for constant data, ie the 86 * CURBEs. 87 * 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. 93 * 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. 102 * 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 descisions 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. 108 * 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. 112 * 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. 116 * 117 * CC - Color Calculator. No EU threads associated with this unit. 118 * Handles blending and (presumably) depth and stencil testing. 119 */ 120 121 122 #define BRW_MAX_CURBE (32*16) 123 124 struct brw_context; 125 struct brw_instruction; 126 struct brw_vs_prog_key; 127 struct brw_wm_prog_key; 128 struct brw_wm_prog_data; 129 130 enum brw_state_id { 131 BRW_STATE_URB_FENCE, 132 BRW_STATE_FRAGMENT_PROGRAM, 133 BRW_STATE_VERTEX_PROGRAM, 134 BRW_STATE_INPUT_DIMENSIONS, 135 BRW_STATE_CURBE_OFFSETS, 136 BRW_STATE_REDUCED_PRIMITIVE, 137 BRW_STATE_PRIMITIVE, 138 BRW_STATE_CONTEXT, 139 BRW_STATE_WM_INPUT_DIMENSIONS, 140 BRW_STATE_PSP, 141 BRW_STATE_SURFACES, 142 BRW_STATE_VS_BINDING_TABLE, 143 BRW_STATE_GS_BINDING_TABLE, 144 BRW_STATE_PS_BINDING_TABLE, 145 BRW_STATE_INDICES, 146 BRW_STATE_VERTICES, 147 BRW_STATE_BATCH, 148 BRW_STATE_NR_WM_SURFACES, 149 BRW_STATE_NR_VS_SURFACES, 150 BRW_STATE_INDEX_BUFFER, 151 BRW_STATE_VS_CONSTBUF, 152 BRW_STATE_PROGRAM_CACHE, 153 BRW_STATE_STATE_BASE_ADDRESS, 154 BRW_STATE_SOL_INDICES, 155 }; 156 157 #define BRW_NEW_URB_FENCE (1 << BRW_STATE_URB_FENCE) 158 #define BRW_NEW_FRAGMENT_PROGRAM (1 << BRW_STATE_FRAGMENT_PROGRAM) 159 #define BRW_NEW_VERTEX_PROGRAM (1 << BRW_STATE_VERTEX_PROGRAM) 160 #define BRW_NEW_INPUT_DIMENSIONS (1 << BRW_STATE_INPUT_DIMENSIONS) 161 #define BRW_NEW_CURBE_OFFSETS (1 << BRW_STATE_CURBE_OFFSETS) 162 #define BRW_NEW_REDUCED_PRIMITIVE (1 << BRW_STATE_REDUCED_PRIMITIVE) 163 #define BRW_NEW_PRIMITIVE (1 << BRW_STATE_PRIMITIVE) 164 #define BRW_NEW_CONTEXT (1 << BRW_STATE_CONTEXT) 165 #define BRW_NEW_WM_INPUT_DIMENSIONS (1 << BRW_STATE_WM_INPUT_DIMENSIONS) 166 #define BRW_NEW_PSP (1 << BRW_STATE_PSP) 167 #define BRW_NEW_SURFACES (1 << BRW_STATE_SURFACES) 168 #define BRW_NEW_VS_BINDING_TABLE (1 << BRW_STATE_VS_BINDING_TABLE) 169 #define BRW_NEW_GS_BINDING_TABLE (1 << BRW_STATE_GS_BINDING_TABLE) 170 #define BRW_NEW_PS_BINDING_TABLE (1 << BRW_STATE_PS_BINDING_TABLE) 171 #define BRW_NEW_INDICES (1 << BRW_STATE_INDICES) 172 #define BRW_NEW_VERTICES (1 << BRW_STATE_VERTICES) 173 /** 174 * Used for any batch entry with a relocated pointer that will be used 175 * by any 3D rendering. 176 */ 177 #define BRW_NEW_BATCH (1 << BRW_STATE_BATCH) 178 /** \see brw.state.depth_region */ 179 #define BRW_NEW_INDEX_BUFFER (1 << BRW_STATE_INDEX_BUFFER) 180 #define BRW_NEW_VS_CONSTBUF (1 << BRW_STATE_VS_CONSTBUF) 181 #define BRW_NEW_PROGRAM_CACHE (1 << BRW_STATE_PROGRAM_CACHE) 182 #define BRW_NEW_STATE_BASE_ADDRESS (1 << BRW_STATE_STATE_BASE_ADDRESS) 183 #define BRW_NEW_SOL_INDICES (1 << BRW_STATE_SOL_INDICES) 184 185 struct brw_state_flags { 186 /** State update flags signalled by mesa internals */ 187 GLuint mesa; 188 /** 189 * State update flags signalled as the result of brw_tracked_state updates 190 */ 191 GLuint brw; 192 /** State update flags signalled by brw_state_cache.c searches */ 193 GLuint cache; 194 }; 195 196 #define AUB_TRACE_TYPE_MASK 0x0000ff00 197 #define AUB_TRACE_TYPE_NOTYPE (0 << 8) 198 #define AUB_TRACE_TYPE_BATCH (1 << 8) 199 #define AUB_TRACE_TYPE_VERTEX_BUFFER (5 << 8) 200 #define AUB_TRACE_TYPE_2D_MAP (6 << 8) 201 #define AUB_TRACE_TYPE_CUBE_MAP (7 << 8) 202 #define AUB_TRACE_TYPE_VOLUME_MAP (9 << 8) 203 #define AUB_TRACE_TYPE_1D_MAP (10 << 8) 204 #define AUB_TRACE_TYPE_CONSTANT_BUFFER (11 << 8) 205 #define AUB_TRACE_TYPE_CONSTANT_URB (12 << 8) 206 #define AUB_TRACE_TYPE_INDEX_BUFFER (13 << 8) 207 #define AUB_TRACE_TYPE_GENERAL (14 << 8) 208 #define AUB_TRACE_TYPE_SURFACE (15 << 8) 209 210 /** 211 * state_struct_type enum values are encoded with the top 16 bits representing 212 * the type to be delivered to the .aub file, and the bottom 16 bits 213 * representing the subtype.
