Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base.
It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and
the base is:
commit 0917f823c59692d751951bf5ea699a2d1e2f26a2

Prepare v4.1.3-rt3
Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

Wysocki <rafael.j.wysocki@intel.com> +Description: + The /sys/devices/.../power_state attribute is only present for + device objects representing ACPI device nodes that provide power + management methods. + + If present, it contains a string representing the current ACPI + power state of the given device node. Its possible values, + "D0", "D1", "D2", "D3hot", and "D3cold", reflect the power state + names defined by the ACPI specification (ACPI 4 and above). + + If the device node uses shared ACPI power resources, this state + determines a list of power resources required not to be turned + off. However, some power resources needed by the device node in + higher-power (lower-number) states may also be ON because of + some other devices using them at the moment. + + This attribute is read-only. |
