Message-ID: <55715800.3000202@zoho.com> (raw)
In-Reply-To: <CAGXu5jKXZHU-GTuNaTCP1_yjxZrGuPHyx8gmb2G6g_HcPzsNkA@mail.gmail.com>
In next, it was fixed by
http://cgit.freedesktop.org/drm-intel/commit/drivers/gpu/drm/i915/i915_gem_execbuffer.c?h=for-linux-next&id=c7c7372edc4ebc173ad359aeb5752e9ce09f2741
In 4.1, the problem only exists with the marked-as-unsafe parameter
i915.enable_ppgtt=2. (It could be fixed there with
http://lists.freedesktop.org/archives/intel-gfx/2015-May/066259.html ,
but doing so at this late stage would be risky.)
