I have revived the PSR interrupt patches that Daniel and Ville had worked on [1], added debugfs control for the interrupts and exposed interrupt timestamps via debugfs. The idea is to provide a mechanism for CI tests to know whether a PSR exit event succeeded and if PSR re-enters when it is expected to do so. This series was tested on a SKL laptop.
