From 2e64a2f2d1f83c9f0ec6ba31ed92620abf221f86 Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Wed, 4 Jul 2018 14:40:25 +0200 Subject: [PATCH] mesa: verify MaxVertexAttribStride for GL 4.4 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The OpenGL 4.4 specification, table Table 23.55 ("Implementation Dependent Values"), defines the minimum-maximum value for MAX_VERTEX_ATTRIB_STRIDE to be 2048. So we shouldn't enable OpenGL 4.4 on implementations where this isn't the case. Let's add a check for this.
