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 spawining 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 contigous + * 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 GEN4 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. + * + * 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. + */ + +#define BRW_FALLBACK_TEXTURE 0x1 +#define BRW_MAX_CURBE (32*16) + +struct brw_context; + +#define BRW_NEW_URB_FENCE 0x1 +#define BRW_NEW_FRAGMENT_PROGRAM 0x2 +#define BRW_NEW_VERTEX_PROGRAM 0x4 +#define BRW_NEW_INPUT_DIMENSIONS 0x8 +#define BRW_NEW_CURBE_OFFSETS 0x10 +#define BRW_NEW_REDUCED_PRIMITIVE 0x20 +#define BRW_NEW_PRIMITIVE 0x40 +#define BRW_NEW_CONTEXT 0x80 +#define BRW_NEW_WM_INPUT_DIMENSIONS 0x100 +#define BRW_NEW_INPUT_VARYING 0x200 +#define BRW_NEW_TNL_PROGRAM 0x400 +#define BRW_NEW_PSP 0x800 +#define BRW_NEW_METAOPS 0x1000 +#define BRW_NEW_FENCE 0x2000 + + + +struct brw_state_flags { + GLuint mesa; + GLuint cache; + GLuint brw; +}; + +struct brw_vertex_program { + struct gl_vertex_program program; + GLuint id; + GLuint param_state; /* flags indicating state tracked by params */ +}; + + + +struct brw_fragment_program { + struct gl_fragment_program program; + GLuint id; + GLuint param_state; /* flags indicating state tracked by params */ +}; + + + + +/* Data about a particular attempt to compile a program.
