The two obvious ways * to deal with it are: * - each shader has multiple variants for each combination of emulated states, * and the variants are compiled on demand, possibly relying on a shader * cache for good performance * - patch shaders at the binary level * * This driver uses something completely different. The emulated states are * usually implemented at the beginning or end of shaders. Therefore, we can * split the shader into 3 parts: * - prolog part (shader code dependent on states) * - main part (the API shader) * - epilog part (shader code dependent on states) * * Each part is compiled as a separate shader and the final binaries are * concatenated. This type of shader is called non-monolithic, because it * consists of multiple independent binaries. Creating a new shader variant * is therefore only a concatenation of shader parts (binaries) and doesn't * involve any compilation. The main shader parts are the only parts that are * compiled when applications create shader objects. The prolog and epilog * parts are compiled on the first use and saved, so that their binaries can * be reused by many other shaders. * * One of the roles of the prolog part is to compute vertex buffer addresses * for vertex shaders. A few of the roles of the epilog part are color buffer * format conversions in pixel shaders that we have to do manually, and write * tessellation factors in tessellation control shaders. The prolog and epilog * have many other important responsibilities in various shader stages. * They don't just "emulate legacy stuff". * * Monolithic shaders are shaders where the parts are combined before LLVM * compilation, and the whole thing is compiled and optimized as one unit with * one binary on the output. The result is the same as the non-monolithic * shader, but the final code can be better, because LLVM can optimize across * all shader parts. Monolithic shaders aren't usually used except for these * special cases: * * 1) Some rarely-used states require modification of the main shader part * itself, and in such cases, only the monolithic shader variant is * compiled, and that's always done on the first use. * * 2) When we do cross-stage optimizations for separate shader objects and * e.g. eliminate unused shader varyings, the resulting optimized shader * variants are always compiled as monolithic shaders, and always * asynchronously (i.e. not stalling ongoing rendering). We call them * "optimized monolithic" shaders. The important property here is that * the non-monolithic unoptimized shader variant is always available for use * when the asynchronous compilation of the optimized shader is not done * yet. * * Starting with GFX9 chips, some shader stages are merged, and the number of * shader parts per shader increased. The complete new list of shader parts is: * - 1st shader: prolog part * - 1st shader: main part * - 2nd shader: prolog part * - 2nd shader: main part * - 2nd shader: epilog part */ /* How linking shader inputs and outputs between vertex, tessellation, and * geometry shaders works. * * Inputs and outputs between shaders are stored in a buffer. This buffer * lives in LDS (typical case for tessellation), but it can also live * in memory (ESGS). Each input or output has a fixed location within a vertex. * The highest used input or output determines the stride between vertices. * * Since GS and tessellation are only possible in the OpenGL core profile, * only these semantics are valid for per-vertex data: * * Name Location * * POSITION 0 * PSIZE 1 * CLIPDIST0..1 2..3 * CULLDIST0..1 (not implemented) * GENERIC0..31 4..35 * * For example, a shader only writing GENERIC0 has the output stride of 5. * * Only these semantics are valid for per-patch data: * * Name Location * * TESSOUTER 0 * TESSINNER 1 * PATCH0..29 2..31 * * That's how independent shaders agree on input and output locations. * The si_shader_io_get_unique_index function assigns the locations. * * For tessellation, other required information for calculating the input and * output addresses like the vertex stride, the patch stride, and the offsets * where per-vertex and per-patch data start, is passed to the shader via * user data SGPRs. The offsets and strides are calculated at draw time and * aren't available at compile time. */ #ifndef SI_SHADER_H #define SI_SHADER_H #include /* LLVMModuleRef */ #include #include "tgsi/tgsi_scan.h" #include "util/u_queue.h" #include "ac_binary.h" #include "ac_llvm_build.h" #include "si_state.h" struct nir_shader; #define SI_MAX_VS_OUTPUTS 40 /* Shader IO unique indices are supported for TGSI_SEMANTIC_GENERIC with an * index smaller than this. */ #define SI_MAX_IO_GENERIC 46 /* SGPR user data indices */ enum { SI_SGPR_RW_BUFFERS, /* rings (& stream-out, VS only) */ #if !HAVE_32BIT_POINTERS SI_SGPR_RW_BUFFERS_HI, #endif SI_SGPR_BINDLESS_SAMPLERS_AND_IMAGES, #if !HAVE_32BIT_POINTERS SI_SGPR_BINDLESS_SAMPLERS_AND_IMAGES_HI, #endif SI_SGPR_CONST_AND_SHADER_BUFFERS, /* or just a constant buffer 0 pointer */ #if !HAVE_32BIT_POINTERS SI_SGPR_CONST_AND_SHADER_BUFFERS_HI, #endif SI_SGPR_SAMPLERS_AND_IMAGES, #if !HAVE_32BIT_POINTERS SI_SGPR_SAMPLERS_AND_IMAGES_HI, #endif SI_NUM_RESOURCE_SGPRS, /* all VS variants */ SI_SGPR_BASE_VERTEX = SI_NUM_RESOURCE_SGPRS, SI_SGPR_START_INSTANCE, SI_SGPR_DRAWID, SI_SGPR_VS_STATE_BITS, SI_VS_NUM_USER_SGPR, SI_SGPR_VS_BLIT_DATA = SI_SGPR_CONST_AND_SHADER_BUFFERS, /* TES */ SI_SGPR_TES_OFFCHIP_LAYOUT = SI_NUM_RESOURCE_SGPRS, SI_SGPR_TES_OFFCHIP_ADDR, SI_TES_NUM_USER_SGPR, /* GFX6-8: TCS only */ GFX6_SGPR_TCS_OFFCHIP_LAYOUT = SI_NUM_RESOURCE_SGPRS, GFX6_SGPR_TCS_OUT_OFFSETS, GFX6_SGPR_TCS_OUT_LAYOUT, GFX6_SGPR_TCS_IN_LAYOUT, GFX6_TCS_NUM_USER_SGPR, /* GFX9: Merged shaders. */ #if HAVE_32BIT_POINTERS /* 2ND_CONST_AND_SHADER_BUFFERS is set in USER_DATA_ADDR_LO (SGPR0). */ /* 2ND_SAMPLERS_AND_IMAGES is set in USER_DATA_ADDR_HI (SGPR1). */ GFX9_MERGED_NUM_USER_SGPR = SI_VS_NUM_USER_SGPR, #else /* 2ND_CONST_AND_SHADER_BUFFERS is set in USER_DATA_ADDR_LO/HI (SGPR[0:1]). */ GFX9_SGPR_2ND_SAMPLERS_AND_IMAGES = SI_VS_NUM_USER_SGPR, GFX9_SGPR_2ND_SAMPLERS_AND_IMAGES_HI, GFX9_MERGED_NUM_USER_SGPR, #endif /* GFX9: Merged LS-HS (VS-TCS) only. */ GFX9_SGPR_TCS_OFFCHIP_LAYOUT = GFX9_MERGED_NUM_USER_SGPR, GFX9_SGPR_TCS_OUT_OFFSETS, GFX9_SGPR_TCS_OUT_LAYOUT, #if !HAVE_32BIT_POINTERS GFX9_SGPR_align_for_vb_pointer, #endif GFX9_TCS_NUM_USER_SGPR, /* GS limits */ GFX6_GS_NUM_USER_SGPR = SI_NUM_RESOURCE_SGPRS, GFX9_GS_NUM_USER_SGPR = GFX9_MERGED_NUM_USER_SGPR, SI_GSCOPY_NUM_USER_SGPR = SI_SGPR_RW_BUFFERS + (HAVE_32BIT_POINTERS ?
