From: Dominik Brodowski Date: Fri, 23 Apr 2010 18:32:23 +0000 (+0200) Subject: PM / Runtime: Add sysfs debug files X-Git-Tag: v2.6.35-rc1~484^2~12 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c92445fadb9179d811b5cb044947ad4712403541;p=pandora-kernel.git PM / Runtime: Add sysfs debug files Add a few sysfs files relating to runtime power management for advanced debug purposes: runtime_enabled: is runtime PM enabled for this device? States are "enabled", "disabled", "forbidden" or a combination of the latter two. runtime_status: what state is the device in currently? E.g., it reports "suspended" for runtime-suspended devices, and "active" for active devices. NOTE: if runtime_enabled returns "disabled", the value of this file may not reflect its physical state. runtime_usage: the runtime PM usage count of a device runtime_active_kids: the runtime PM children usage count of a device, or 0 if the ignore_children flag is set. Also, CONFIG_PM_SLEEP_ADVANCED_DEBUG is not defined in any Kconfig file, so replace it with CONFIG_PM_ADVANCED_DEBUG. Signed-off-by: Dominik Brodowski Acked-by: Alan Stern Signed-off-by: Rafael J.
