Subject: [PATCH 0/2] ACPI / PCI / PM: Delay resuming runtine-suspended devices during system-suspend
Date: Mon, 24 Feb 2014 00:18:22 +0100 [thread overview]
Message-ID: <1853950.oxM3KDpyLu@vostro.rjw.lan> (raw)
Hi All,
The PCI bus type and the ACPI PM domain resume runtime-suspended devices during
their .prepare() callbacks, which is suboptimal.
One problem caused by that is increasing the time of system suspend if there
are many runtime-suspended devices to resume during it (because the .prepare()
callbacks are executed sequentially).
The following two patches are intended to improve that one aspect slightly
in those two subsystems.
Thanks!
