Subject: [driver-core PATCH v10 7/9] PM core: Use new async_schedule_dev command
Date: Tue, 22 Jan 2019 10:39:42 -0800 [thread overview]
Message-ID: <154818238223.18753.9585851073401018816.stgit@ahduyck-desk1.amr.corp.intel.com> (raw)
In-Reply-To: <154818223154.18753.12374915684623789884.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.
