29 /* The compiler middle-end architecture: Explaining (non-)monolithic shaders
30 * -------------------------------------------------------------------------
32 * Typically, there is one-to-one correspondence between API and HW shaders,
33 * that is, for every API shader, there is exactly one shader binary in
36 * The problem with that is that we also have to emulate some API states
37 * (e.g. alpha-test, and many others) in shaders too. The two obvious ways
38 * to deal with it are:
39 * - each shader has multiple variants for each combination of emulated states,
40 * and the variants are compiled on demand, possibly relying on a shader
41 * cache for good performance
42 * - patch shaders at the binary level
44 * This driver uses something completely different. The emulated states are
45 * usually implemented at the beginning or end of shaders. Therefore, we can
46 * split the shader into 3 parts:
47 * - prolog part (shader code dependent on states)
48 * - main part (the API shader)
49 * - epilog part (shader code dependent on states)
51 * Each part is compiled as a separate shader and the final binaries are
52 * concatenated. This type of shader is called non-monolithic, because it
53 * consists of multiple independent binaries. Creating a new shader variant
54 * is therefore only a concatenation of shader parts (binaries) and doesn't
55 * involve any compilation. The main shader parts are the only parts that are
56 * compiled when applications create shader objects. The prolog and epilog
57 * parts are compiled on the first use and saved, so that their binaries can
58 * be reused by many other shaders.
60 * One of the roles of the prolog part is to compute vertex buffer addresses
61 * for vertex shaders. A few of the roles of the epilog part are color buffer
62 * format conversions in pixel shaders that we have to do manually, and write
63 * tessellation factors in tessellation control shaders. The prolog and epilog
64 * have many other important responsibilities in various shader stages.
65 * They don't just "emulate legacy stuff".
67 * Monolithic shaders are shaders where the parts are combined before LLVM
68 * compilation, and the whole thing is compiled and optimized as one unit with
69 * one binary on the output. The result is the same as the non-monolithic
70 * shader, but the final code can be better, because LLVM can optimize across
71 * all shader parts. Monolithic shaders aren't usually used except for these
74 * 1) Some rarely-used states require modification of the main shader part
75 * itself, and in such cases, only the monolithic shader variant is
76 * compiled, and that's always done on the first use.
78 * 2) When we do cross-stage optimizations for separate shader objects and
79 * e.g. eliminate unused shader varyings, the resulting optimized shader
80 * variants are always compiled as monolithic shaders, and always
81 * asynchronously (i.e. not stalling ongoing rendering). We call them
82 * "optimized monolithic" shaders. The important property here is that
83 * the non-monolithic unoptimized shader variant is always available for use
84 * when the asynchronous compilation of the optimized shader is not done
87 * Starting with GFX9 chips, some shader stages are merged, and the number of
88 * shader parts per shader increased. The complete new list of shader parts is:
89 * - 1st shader: prolog part
90 * - 1st shader: main part
91 * - 2nd shader: prolog part
92 * - 2nd shader: main part
93 * - 2nd shader: epilog part
96 /* How linking shader inputs and outputs between vertex, tessellation, and
97 * geometry shaders works.
99 * Inputs and outputs between shaders are stored in a buffer. This buffer
100 * lives in LDS (typical case for tessellation), but it can also live
101 * in memory (ESGS). Each input or output has a fixed location within a vertex.
102 * The highest used input or output determines the stride between vertices.
104 * Since GS and tessellation are only possible in the OpenGL core profile,
105 * only these semantics are valid for per-vertex data:
112 * CULLDIST0..1 (not implemented)
115 * For example, a shader only writing GENERIC0 has the output stride of 5.
117 * Only these semantics are valid for per-patch data:
125 * That's how independent shaders agree on input and output locations.
126 * The si_shader_io_get_unique_index function assigns the locations.
128 * For tessellation, other required information for calculating the input and
129 * output addresses like the vertex stride, the patch stride, and the offsets
130 * where per-vertex and per-patch data start, is passed to the shader via
131 * user data SGPRs. The offsets and strides are calculated at draw time and
132 * aren't available at compile time.
