From a1e4d72cd3024999bfb6703092ea271438805c89 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 8 Feb 2010 19:16:33 +0100 Subject: PM: Allow PCI devices to suspend/resume asynchronously Set power.async_suspend for all PCI devices and PCIe port services, so that they can be suspended and resumed in parallel with other devices they don't depend on in a known way (i.e. devices which are not their parents or children). This only affects the "regular" suspend and resume stages, which means in particular that the restoration of the PCI devices' standard configuration registers during resume will still be carried out synchronously (at the "early" resume stage).
