From: Nicolai Hähnle Date: Sat, 3 Oct 2015 22:44:00 +0000 (+0200) Subject: u_vbuf: fix vb slot assignment for translated buffers X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=45ed627d894aa4d51682e8b07e7234bbc6e7c02d;p=mesa.git u_vbuf: fix vb slot assignment for translated buffers Vertex attributes of different categories (constant/per-instance/ per-vertex) go into different buffers for translation, and this is now properly reflected in the vertex buffers passed to the driver. Fixes e.g. piglit's point-vertex-id divisor test.
