From 747cf468ff41067513b6893e2fcd2b22b18e1c9b Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Fri, 6 Jul 2018 10:29:02 +0200 Subject: [PATCH] r600: report incorrect max-vertex-attrib for GL 4.4 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit OpenGL 4.4 requires a max vertex attrib of 2048 or higher, but r600 only supports 2047. Technically, this makes it an GL4.3 GPU, but it's currently exposing GL4.4. To avoid regressing the GL version supported in the following patches, let's just lie and pretend like we support 2048. Any applications using 2048 are already broken anyway.
