    tools/power/acpi: Add userspace AML interface support · 37645d65
    Lv Zheng authored
    This patch adds a userspace tool to access Linux kernel AML debugger
    Tow modes are supported by this tool:
    1. Interactive: Users are able to launch a debugging shell to talk with
       in-kernel AML debugger.
       Note that it's user duty to ensure kernel runtime integrity by using
       this debugging tool:
       A. Some control methods evaluated by the users may result in kernel
          panics if those control methods shouldn't be evaluated by the OSPMs
          according to the current BIOS/OS configurations.
       B. Currently if a single stepping evaluation couldn't run to an end,
          then the synchronization primitives acquired by the evaluation may
          block normal OSPM control method evaluations.
    2. Batch: Users are able to execute debugger commands in a script.
       Note that in addition to the above duties, it's user duty to ensure
       script runtime integrity by using this debugging tool in this mode:
       C. Currently only those commands that are not used for single stepping
          are suitable to be used in this mode.
       D. If the execution of the command may cause a failure that could result
          in an endless kernel execution, the execution of the script may also
          get blocked.
    To exit the utility, currently "exit/quit" commands are recommended, but
    ctrl-C" can also be used.
