This will require a bit more thought since it isn't trivially cherry-pick into 3.16. So far I have the following patchset that still requires some backporting: d6a4f70909d279004a2b3d539e240e07b1ecc1cb * added * 56548fc0e86cb9156af7a7e1f15ba78f251dafaf 8117ac6a6c2fa0f847ff6a21a1f32c8d2c8501d0 74aa51b5ccd3975392e30d11820dc073c5f2cd32 * added * 8eb8ac89a364305d05ad16be983b7890eb462cc3 6d626c5ea3d8411cc2a72d7cabe70f01dfc32d1d * added (backport) * 7cba160ad789a3ad7e68b92bf20eaad6ed171f80 * backport * 77b54e9f213f76a23736940cf94bcd765fc00f40
Obviously only introducing the required features would be optimal. Feedback on backport strategy would be appreciated. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1400411 Title: Feature: cpuidle: Enable fastsleep and winkle in ubuntu 14.04.02 kernel Status in linux package in Ubuntu: New Status in linux source package in Utopic: In Progress Bug description: SRU Justification: Impact: Users would like to be able to use fastsleep and winkle cpuidle states in the 3.16 Ubuntu kernel when using powernv.
