Chris Wilson d60996ab43 drm/i915: Restore user forcewake domains across suspend ... On suspend, we cancel the automatic forcewake and clear all other sources of forcewake so the machine can sleep before we do suspend. However, we expose the forcewake to userspace (only via debugfs, but nevertheless we do) and want to restore that upon resume or else our accounting will be off and we may not acquire the forcewake before we use it. So record which domains we cleared on suspend and reacquire them early on resume. v2: Hold the spinlock to appease our sanitychecks v3: s/fw_domains_user/fw_domains_saved/ to convey intent more clearly Reported-by: Imre Deak <imre.deak@linux.intel.com> Fixes: b847305080 ("drm/i915: Fix forcewake active domain tracking") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Cc: Imre Deak <imre.deak@linux.intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180808210842.3555-1-chris@chris-wilson.co.uk		2018-08-09 14:25:46 +01:00
