From: Jeff McGee <jeff.mcgee@xxxxxxxxx> This series has recently been accepted into the Haswell Android kernel and helps with debugging and profiling these power features. I would like it to be considered for upstream incorporation. The patches here have been rebased (minimal changes required) and compile-tested only. Broad device support is provided, accept for RPS and RC6 with Broadwell and Valleyview. Both of these were somewhat of a moving target and I didn't have devices to work with. Support can of course be added with help from appropriate folks. The hooks introduce some amount of overhead as an additional check is often needed to determine whether the feature is on or off - similar to the module parameters that already exist. I felt that the overhead was minimal enough and didn't want to ugly up the code with CONFIG_DEBUG_FS compile conditionals. But I'm open to the list's thoughts on this. IGT tests of these new interfaces can certainly be added. I wanted to make sure there was sufficient interest in having these interfaces before starting on the tests. So please provide feedback.
