  29 /* How linking shader inputs and outputs between vertex, tessellation, and
  30  * geometry shaders works.
  31  *
  32  * Inputs and outputs between shaders are stored in a buffer. This buffer
  33  * lives in LDS (typical case for tessellation), but it can also live
  34  * in memory (ESGS). Each input or output has a fixed location within a vertex.
  35  * The highest used input or output determines the stride between vertices.
  36  *
  37  * Since GS and tessellation are only possible in the OpenGL core profile,
  38  * only these semantics are valid for per-vertex data:
  39  *
  40  *   Name             Location
  41  *
  42  *   POSITION         0
  43  *   PSIZE            1
  44  *   CLIPDIST0..1     2..3
  45  *   CULLDIST0..1     (not implemented)
  46  *   GENERIC0..31     4..35
  47  *
  48  * For example, a shader only writing GENERIC0 has the output stride of 5.
  49  *
  50  * Only these semantics are valid for per-patch data:
  51  *
  52  *   Name             Location
  53  *
  54  *   TESSOUTER        0
  55  *   TESSINNER        1
  56  *   PATCH0..29       2..31
  57  *
  58  * That's how independent shaders agree on input and output locations.
  59  * The si_shader_io_get_unique_index function assigns the locations.
  60  *
  61  * For tessellation, other required information for calculating the input and
  62  * output addresses like the vertex stride, the patch stride, and the offsets
  63  * where per-vertex and per-patch data start, is passed to the shader via
  64  * user data SGPRs. The offsets and strides are calculated at draw time and
  65  * aren't available at compile time.
