Bug Description
This is a feature request to include the following patches in 14.04.03 kernel.
[1] 74aa51b5ccd39753 cpuidle: powernv: Populate cpuidle state details by querying the device-tree
(3.18 upstream)
[2] cpuidle/powernv: Read target_residency value of idle states from DT if available
https:/
[3] tick/broadcast-
http://
[1] and [2] patches provide fixes to read the latency and target_residency values of different idle states from the device tree if they are present in the device tree. This fix will avoid cpu from aggressively entering into fastsleep.
[3] is an important fix against a kernel regression down the cpuidle path which was reported in the community.
