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. <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/archives/beignet/2015-May/005642.html"><a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/archives/beignet/2015-May/005642.html">http://lists.freedesktop.org/archives/beignet/2015-May/005642.html</a></a>).
