Mika Kuoppala 9b18572e83 drm/i915/gen9: Verify and enforce dc6 state writes ... It has been observed that sometimes disabling the dc6 fails and dc6 state pops back up, brief moment after disabling. This has to be dmc save/restore timing issue or other bug in the way dc states are handled. Try to work around this issue as we don't have firmware fix yet available. Verify that the value we wrote for the dmc sticks, and also enforce it by rewriting it, if it didn't. v2: Zero rereads on rewrite for extra paranoia (Imre) Testcase: kms_flip/basic-flip-vs-dpms References: https://bugs.freedesktop.org/show_bug.cgi?id=93768 Cc: Patrik Jakobsson <patrik.jakobsson@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Imre Deak <imre.deak@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Imre Deak <imre.deak@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1455811089-27884-1-git-send-email-mika.kuoppala@intel.com (cherry picked from commit 779cb5d3dd) Signed-off-by: Jani Nikula <jani.nikula@intel.com>		2016-02-22 18:37:43 +02:00
