From f19f3f5496de7e65a937ccf88812d303d0054a8f Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 26 May 2021 15:53:46 +1000 Subject: [PATCH] draw/tess: write correct primitive id into vertices The code was using a prim assembler after the tess stage, however tess prims aren't necessarily the output prim types, so just put the prim ids into the vertices at tess stage, and skip prim assembly.
