From 8ba157006fe98bca96b79bea1394b0c33ddf4ad3 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Wed, 26 Feb 2014 12:32:29 -0800 Subject: [PATCH] i915: Only allow 8 vertex texture units There's no reason to have more vertex texture units than fragment texture units on this hardware. Since increasing the default maximum number of texture units from 16 to 32, this has triggered some segfault in i915 driver. There's probably some array or bitfield that isn't properly sized now. This really papers over the bug, but I don't think I'll lose any sleep over that.
