From d91e657876a96af4f00cc374e26a7a9e8c40d6de Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 24 Apr 2019 21:07:13 +0100 Subject: drm/i915: Introduce struct intel_wakeref For controlling runtime pm of the GT and engines, we would like to have a callback to do extra work the first time we wake up and the last time we drop the wakeref. This first/last access needs serialisation and so we encompass a mutex with the regular intel_wakeref_t tracker. v2: Drop the _once naming and report the errors.
