VGT_SHADER_STAGES_EN.GS_FAST_LAUNCH = 1 (mesh-style NGG, as RADV programs it on gfx10.3) was refused. With a point list and GE_CNTL groups of one point, it launches one subgroup per input point and the first thread reads that point's index in the ES vertex id VGPR, which the mesh prologue already provides. The subgroup's primitive limit comes from GE_NGG_SUBGRP_CNTL.PRIM_AMP_FACTOR, and the GS and ES VGPR counts are not required to be full. Fast launch 2, other group sizes or inputs, and indexed fast-launch draws still throw. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |
