From 9f9d9c948dc665875672b5c2ee034aca18ccaf71 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 27 Mar 2019 14:06:50 +1000 Subject: [PATCH] softpipe/draw: fix vertex id in soft paths. This fixes the vertex id fetch in the non-llvm drawing paths. This vertex id in elt mode comes from the elts not just a linear value. Note we don't bad basevertex in the elts case as it's already included in the elts by the looks of it (at least tests fail if I add it) Fixes piglit end-primitive tests and some others.
