119 An important difference is that VS is always the first stage to run in SW models,
120 whereas HW VS refers to the last HW stage before fragment shading in GCN/RDNA terminology.
121 That's why, among other things, the HW VS is no longer used to execute the SW VS when tesselation o…

134 * LS = Local Shader (merged into HS on GFX9+), only runs SW VS when tessellation is used

143 ##### Notes about HW VS and the "GS copy" shader
145 HW PS reads its inputs from a special buffer that only HW VS can write to, using export instruction…
147 So in order for HW PS to be able to read the GS outputs, we must run something on the VS stage whic…
149 From a HW perspective the "GS copy" shader is in fact VS (it runs on the HW VS stage),
157 …GFX9 (and GFX10/legacy) are: LSHS and ESGS. On GFX10/NGG the ESGS is merged with HW VS into NGG GS.
174 * GS outputs got to VRAM, so they have to be copied by a GS copy shader running on the HW VS stage
