Imre Deak ab3be73fa7 drm/i915: gen4: work around hang during hibernation ... Bjørn reported that his machine hang during hibernation and eventually bisected the problem to the following commit: commit da2bc1b9db Author: Imre Deak <imre.deak@intel.com> Date: Thu Oct 23 19:23:26 2014 +0300 drm/i915: add poweroff_late handler The problem seems to be that after the kernel puts the device into D3 the BIOS still tries to access it, or otherwise assumes that it's in D0. This is clearly bogus, since ACPI mandates that devices are put into D3 by the OSPM if they are not wake-up sources. In the future we want to unify more of the driver's runtime and system suspend paths, for example by skipping all the system suspend/hibernation hooks if the device is runtime suspended already. Accordingly for all other platforms the goal is still to properly power down the device during hibernation. v2: - Another GEN4 Lenovo laptop had the same issue, while platforms from other vendors (including mobile and desktop, GEN4 and non-GEN4) seem to work fine. Based on this apply the workaround on all GEN4 Lenovo platforms. - add code comment about failing platforms (Ville) Reference: http://lists.freedesktop.org/archives/intel-gfx/2015-February/060633.html Reported-and-bisected-by: Bjørn Mork <bjorn@mork.no> Cc: stable@vger.kernel.org # v3.19 Signed-off-by: Imre Deak <imre.deak@intel.com> Acked-by: Daniel Vetter <daniel.vetter@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>		2015-03-04 10:08:50 +02:00
