A mid-sized buffer which is - * partitioned between the fixed function units and used for passing - * values (vertices, primitives, constants) between them. - * - * CURBE - constant URB entry. An urb region (entry) used to hold - * constant values which the fixed function units can be instructed to - * preload into the GRF when spawning a thread. - * - * VUE - vertex URB entry. An urb entry holding a vertex and usually - * a vertex header. The header contains control information and - * things like primitive type, Begin/end flags and clip codes. - * - * PUE - primitive URB entry. An urb entry produced by the setup (SF) - * unit holding rasterization and interpolation parameters. - * - * GRF - general register file. One of several register files - * addressable by programmed threads. The inputs (r0, payload, curbe, - * urb) of the thread are preloaded to this area before the thread is - * spawned. The registers are individually 8 dwords wide and suitable - * for general usage. Registers holding thread input values are not - * special and may be overwritten. - * - * MRF - message register file. Threads communicate (and terminate) - * by sending messages. Message parameters are placed in contiguous - * MRF registers. All program output is via these messages. URB - * entries are populated by sending a message to the shared URB - * function containing the new data, together with a control word, - * often an unmodified copy of R0. - * - * R0 - GRF register 0. Typically holds control information used when - * sending messages to other threads. - * - * EU or GFX4 EU: The name of the programmable subsystem of the - * i965 hardware. Threads are executed by the EU, the registers - * described above are part of the EU architecture. - * - * Fixed function units: - * - * CS - Command streamer. Notional first unit, little software - * interaction. Holds the URB entries used for constant data, ie the - * CURBEs. - * - * VF/VS - Vertex Fetch / Vertex Shader. The fixed function part of - * this unit is responsible for pulling vertices out of vertex buffers - * in vram and injecting them into the processing pipe as VUEs. If - * enabled, it first passes them to a VS thread which is a good place - * for the driver to implement any active vertex shader. - * - * HS - Hull Shader (Tessellation Control Shader) - * - * TE - Tessellation Engine (Tessellation Primitive Generation) - * - * DS - Domain Shader (Tessellation Evaluation Shader) - * - * GS - Geometry Shader. This corresponds to a new DX10 concept. If - * enabled, incoming strips etc are passed to GS threads in individual - * line/triangle/point units. The GS thread may perform arbitary - * computation and emit whatever primtives with whatever vertices it - * chooses. This makes GS an excellent place to implement GL's - * unfilled polygon modes, though of course it is capable of much - * more. Additionally, GS is used to translate away primitives not - * handled by latter units, including Quads and Lineloops. - * - * CS - Clipper. Mesa's clipping algorithms are imported to run on - * this unit. The fixed function part performs cliptesting against - * the 6 fixed clipplanes and makes descisions on whether or not the - * incoming primitive needs to be passed to a thread for clipping. - * User clip planes are handled via cooperation with the VS thread. - * - * SF - Strips Fans or Setup: Triangles are prepared for - * rasterization. Interpolation coefficients are calculated. - * Flatshading and two-side lighting usually performed here. - * - * WM - Windower. Interpolation of vertex attributes performed here. - * Fragment shader implemented here. SIMD aspects of EU taken full - * advantage of, as pixels are processed in blocks of 16. - * - * CC - Color Calculator. No EU threads associated with this unit. - * Handles blending and (presumably) depth and stencil testing. - */ - -struct brw_context; -struct brw_inst; -struct brw_vs_prog_key; -struct brw_vue_prog_key; -struct brw_wm_prog_key; -struct brw_wm_prog_data; -struct brw_cs_prog_key; -struct brw_cs_prog_data; -struct brw_label; - -enum brw_pipeline { - BRW_RENDER_PIPELINE, - BRW_COMPUTE_PIPELINE, - - BRW_NUM_PIPELINES -}; - -enum brw_cache_id { - BRW_CACHE_FS_PROG, - BRW_CACHE_BLORP_PROG, - BRW_CACHE_SF_PROG, - BRW_CACHE_VS_PROG, - BRW_CACHE_FF_GS_PROG, - BRW_CACHE_GS_PROG, - BRW_CACHE_TCS_PROG, - BRW_CACHE_TES_PROG, - BRW_CACHE_CLIP_PROG, - BRW_CACHE_CS_PROG, - - BRW_MAX_CACHE -}; - -enum gfx9_astc5x5_wa_tex_type { - GFX9_ASTC5X5_WA_TEX_TYPE_ASTC5x5 = 1 << 0, - GFX9_ASTC5X5_WA_TEX_TYPE_AUX = 1 << 1, -}; - -enum brw_state_id { - /* brw_cache_ids must come first - see brw_program_cache.c */ - BRW_STATE_URB_FENCE = BRW_MAX_CACHE, - BRW_STATE_FRAGMENT_PROGRAM, - BRW_STATE_GEOMETRY_PROGRAM, - BRW_STATE_TESS_PROGRAMS, - BRW_STATE_VERTEX_PROGRAM, - BRW_STATE_REDUCED_PRIMITIVE, - BRW_STATE_PATCH_PRIMITIVE, - BRW_STATE_PRIMITIVE, - BRW_STATE_CONTEXT, - BRW_STATE_PSP, - BRW_STATE_SURFACES, - BRW_STATE_BINDING_TABLE_POINTERS, - BRW_STATE_INDICES, - BRW_STATE_VERTICES, - BRW_STATE_DEFAULT_TESS_LEVELS, - BRW_STATE_BATCH, - BRW_STATE_INDEX_BUFFER, - BRW_STATE_VS_CONSTBUF, - BRW_STATE_TCS_CONSTBUF, - BRW_STATE_TES_CONSTBUF, - BRW_STATE_GS_CONSTBUF, - BRW_STATE_PROGRAM_CACHE, - BRW_STATE_STATE_BASE_ADDRESS, - BRW_STATE_VUE_MAP_GEOM_OUT, - BRW_STATE_TRANSFORM_FEEDBACK, - BRW_STATE_RASTERIZER_DISCARD, - BRW_STATE_STATS_WM, - BRW_STATE_UNIFORM_BUFFER, - BRW_STATE_IMAGE_UNITS, - BRW_STATE_META_IN_PROGRESS, - BRW_STATE_PUSH_CONSTANT_ALLOCATION, - BRW_STATE_NUM_SAMPLES, - BRW_STATE_TEXTURE_BUFFER, - BRW_STATE_GFX4_UNIT_STATE, - BRW_STATE_CC_VP, - BRW_STATE_SF_VP, - BRW_STATE_CLIP_VP, - BRW_STATE_SAMPLER_STATE_TABLE, - BRW_STATE_VS_ATTRIB_WORKAROUNDS, - BRW_STATE_COMPUTE_PROGRAM, - BRW_STATE_CS_WORK_GROUPS, - BRW_STATE_URB_SIZE, - BRW_STATE_CC_STATE, - BRW_STATE_BLORP, - BRW_STATE_VIEWPORT_COUNT, - BRW_STATE_CONSERVATIVE_RASTERIZATION, - BRW_STATE_DRAW_CALL, - BRW_STATE_AUX, - BRW_NUM_STATE_BITS -}; - -/** - * BRW_NEW_*_PROG_DATA and BRW_NEW_*_PROGRAM are similar, but distinct. - * - * BRW_NEW_*_PROGRAM relates to the gl_shader_program/gl_program structures. - * When the currently bound shader program differs from the previous draw - * call, these will be flagged.
