    Subject[RFC][PATCH 0/3] ACPI / PM: Export power resources information to user space
    Date
    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
