From 734bef372d80a2ebf5677eb4fbd0e939f2b3cfb4 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Thu, 11 Jan 2018 02:10:25 +0100 Subject: [PATCH] mesa: require at least 14 UBOs for GL 4.3 ARB_ubo requires 12 UBOs (per stage) at least, but this limit has been raised by GL 4.3 to 14, so don't advertize GL 4.3 without it (only checking the vertex stage since all drivers probably have the same limit anyway for other stages). (piglit has minmax tests for that kind of thing, but they go only up to 3.3, so this won't really be noticed.) I think this currently should not affect any driver - r600 until very recently only supported 12 but now advertizes 14 too.
