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_MAX_CURBE (32*16) - -struct brw_context; -struct brw_winsys; - - -/* Raised when we receive new state across the pipe interface: - */ -#define BRW_NEW_VIEWPORT 0x1 -#define BRW_NEW_RASTERIZER 0x2 -#define BRW_NEW_FS 0x4 -#define BRW_NEW_BLEND 0x8 -#define BRW_NEW_CLIP 0x10 -#define BRW_NEW_SCISSOR 0x20 -#define BRW_NEW_STIPPLE 0x40 -#define BRW_NEW_FRAMEBUFFER 0x80 -#define BRW_NEW_ALPHA_TEST 0x100 -#define BRW_NEW_DEPTH_STENCIL 0x200 -#define BRW_NEW_SAMPLER 0x400 -#define BRW_NEW_TEXTURE 0x800 -#define BRW_NEW_CONSTANTS 0x1000 -#define BRW_NEW_VBO 0x2000 -#define BRW_NEW_VS 0x4000 - -/* Raised for other internal events: - */ -#define BRW_NEW_URB_FENCE 0x10000 -#define BRW_NEW_PSP 0x20000 -#define BRW_NEW_CURBE_OFFSETS 0x40000 -#define BRW_NEW_REDUCED_PRIMITIVE 0x80000 -#define BRW_NEW_PRIMITIVE 0x100000 -#define BRW_NEW_SCENE 0x200000 -#define BRW_NEW_SF_LINKAGE 0x400000 - -extern int BRW_DEBUG; - -#define DEBUG_TEXTURE 0x1 -#define DEBUG_STATE 0x2 -#define DEBUG_IOCTL 0x4 -#define DEBUG_PRIMS 0x8 -#define DEBUG_VERTS 0x10 -#define DEBUG_FALLBACKS 0x20 -#define DEBUG_VERBOSE 0x40 -#define DEBUG_DRI 0x80 -#define DEBUG_DMA 0x100 -#define DEBUG_SANITY 0x200 -#define DEBUG_SYNC 0x400 -#define DEBUG_SLEEP 0x800 -#define DEBUG_PIXEL 0x1000 -#define DEBUG_STATS 0x2000 -#define DEBUG_TILE 0x4000 -#define DEBUG_SINGLE_THREAD 0x8000 -#define DEBUG_WM 0x10000 -#define DEBUG_URB 0x20000 -#define DEBUG_VS 0x40000 -#define DEBUG_BATCH 0x80000 -#define DEBUG_BUFMGR 0x100000 -#define DEBUG_BLIT 0x200000 -#define DEBUG_REGION 0x400000 -#define DEBUG_MIPTREE 0x800000 - -#define DBG(...) do { \ - if (BRW_DEBUG & FILE_DEBUG_FLAG) \ - debug_printf(__VA_ARGS__); \ -} while(0) - -#define PRINT(...) do { \ - debug_printf(__VA_ARGS__); \ -} while(0) - -struct brw_state_flags { - unsigned cache; - unsigned brw; -}; - - -struct brw_vertex_program { - struct pipe_shader_state program; - struct tgsi_shader_info info; - int id; -}; - - -struct brw_fragment_program { - struct pipe_shader_state program; - struct tgsi_shader_info info; - - boolean UsesDepth; /* XXX add this to tgsi_shader_info? */ - int id; -}; - - -struct pipe_setup_linkage { - struct { - unsigned vp_output:5; - unsigned interp_mode:4; - unsigned bf_vp_output:5; - } fp_input[PIPE_MAX_SHADER_INPUTS]; - - unsigned fp_input_count:5; - unsigned max_vp_output:5; -}; - - - -struct brw_texture { - struct pipe_texture base; - - /* Derived from the above: - */ - unsigned stride; - unsigned depth_pitch; /* per-image on i945? */ - unsigned total_nblocksy; - - unsigned nr_images[PIPE_MAX_TEXTURE_LEVELS]; - - /* Explicitly store the offset of each image for each cube face or - * depth value.
