commit bafb2f7d4755bf1571bd5e9a03b97f3fc4fe69ae Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Sep 21 14:51:08 2016 +0100 drm/i915/execlists: Reset RING registers upon resume There is a disparity in the context image saved to disk and our own bookkeeping - that is we presume the RING_HEAD and RING_TAIL match our stored ce->ring->tail value. However, as we emit WA_TAIL_DWORDS into the ring but may not tell the GPU about them, the GPU may be lagging behind our bookkeeping. Upon hibernation we do not save stolen pages, presuming that their contents are volatile. This means that although we start writing into the ring at tail, the GPU starts executing from its HEAD and there may be some garbage in between and so the GPU promptly hangs upon resume. Testcase: igt/gem_exec_suspend/basic-S4 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=96526 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20160921135108.29574-3-ch ris@chris-wilson.co.uk *** This bug has been marked as a duplicate of bug 96526 *** Thanks, Chris! # git describe bafb2f7d4755bf1571bd5e9a03b97f3fc4fe69ae v4.8-rc2-641-gbafb2f7d4755 With leap 42.3 we ship a drm-kmp package, which updates drm/KMS to Kernel 4.9, so this fix should already be in. Mawtey, could you verify, that drm-kmp package is installed on your system? rpm -qa | grep drm-kmp > rpm -qa | grep drm-kmp

Ok. Then it needs to be something different ... closing as this is a duplicate (In reply to Stefan Dirsch from comment #6) > Ok. Then it needs to be something different ... If I understand it right, the commit containing this patch has been reverted in the production kernel: ################ commit 0ee72d8f9b8e17b8e4ccfebc7a25cbc2d395cd6a Author: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Date: Wed Apr 12 15:49:39 2017 +0200 Revert "drm/i915/execlists: Reset RING registers upon resume" This reverts commit f2a0409a08502d64fbe3990354dff5902b08d2fb which is commit bafb2f7d4755bf1571bd5e9a03b97f3fc4fe69ae upstream. It was reported to have problems. ################ https://lists.freedesktop.org/archives/intel-gfx/2017-April/125833.html I therefore wonder whether this means this bug is still there in the production kernel. |
