Subject: [driver-core PATCH v7 8/9] PM core: Use new async_schedule_dev command
Date: Wed, 28 Nov 2018 16:32:47 -0800 [thread overview]
Message-ID: <154345156732.18040.4213636216002711880.stgit@ahduyck-desk1.amr.corp.intel.com> (raw)
In-Reply-To: <154345118835.18040.17186161872550839244.stgit@ahduyck-desk1.amr.corp.intel.com>
Use the device specific version of the async_schedule commands to defer
various tasks related to power management. By doing this we should see a
slight improvement in performance as any device that is sensitive to
latency/locality in the setup will now be initializing on the node closest
to the device.
