Hello. Running clinfo in my system spews for a number of times the
warning described in the object. This happens with kernel 4.1.6 and
libdrm 2.4.61 (fedora 22 x86_64), and beignet 1.1.0 (compiled from
source), hardware is i5-3230M (Ivy Brdige). Note that my libdrm version
is higher than the suggested upgrade that apparently fixed the issue for
others (e.g.
http://lists.freedesktop.org/archives/beignet/2015-May/005642.html).
Here's the full clinfo 2>&1 output:
