Hi Greg, The following patch series is about exporting ACPI power resources to user space that will be necessary for PM diagnostics on new platforms (powertop is the target). Still, existing systems can also benefit from that, like my oldish HP nx6325 on which the patches have been tested. Patch [1/3] shouldn't be really controverisal, as it only makes it possible to read power resources' reference counters from user space in a quite straightforward way. Patch [3/3], however, exposes lists of power resources associated with different power states of devices using ACPI PM as sysfs subdirectories containing symbolic links and that requires some sysfs changes made by patch [2/3]. Admittedly, my sysfs skills are limited so please let me know if those changes make sense and are acceptable from your perspective. If not, then please kindly advise what I can do instead of them. The patches apply on top of the current linux-next branch of the linux-pm.git tree. Thanks, Rafael -- I speak only for myself. Rafael J.
