From 7d3f9ed71c71637a91ecf15f50dbe7578a65d57e Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 25 Jan 2017 22:31:58 -0500 Subject: [PATCH] st/mesa: MAX_VARYING is the max supported number of patch varyings, not min MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This fixes GL45-CTS.tessellation_shader.tessellation_shader_tessellation.max_in_out_attributes on nouveau. We only support 30 patch varyings (as 2 vec4 slots end up being used for tess level settings), but were getting 32 exposed.
