  • 362b64606   ACPI: Export FADT pm_profile integer value to userspace ... Browse Code »

    There are a lot userspace approaches to detect the usage of the
    platform (laptop, workstation, server, ...) and adjust kernel tunables
    accordingly (io/process scheduler, power management, ...).

    These approaches need constant maintaining and are ugly to implement
    (detect PCMCIA controller -> laptop,
    does not work on recent systems anymore, ...)
    On ACPI systems there is an easy and reliable way (if implemented
    in BIOS and most recent platforms have this value set).
    -> export it to userspace.

  • 9c8b04be4   ACPI: constify ops structs ... Browse Code »

    Structs battery_file, acpi_dock_ops, file_operations,
    thermal_cooling_device_ops, thermal_zone_device_ops, kernel_param_ops
    are not changed in runtime. It is safe to make them const.
    register_hotplug_dock_device() was altered to take const "ops" argument
    to respect acpi_dock_ops' const notion.

    - Move param aml_debug_output to other params into sysfs.c
    - Split acpi_debugfs_init to prepare custom_method to be
    an own .config option and driver.

  • a0fcdb237   ACPICA: Global event handler ... Browse Code »

    The global event handler is called whenever a general purpose
    or fixed ACPI event occurs.

    Also update Linux OSL to collect events counter with
    global event handler.

    drivers/acpi/sysfs.c:154: warning: passing argument 1 of '__check_old_set_param' from incompatible pointer type
    include/linux/moduleparam.h:165: note: expected 'int (*)(const char *, struct kernel_param *)' but argument is of type 'int (*)(const char *, const struct kernel_param *)'

    Introduced by commit 1c8fce27e275fd7c6b75bc6455745f02d3903ee6 ("ACPI:
    introduce drivers/acpi/sysfs.c") interacting with commit
    9bbb9e5a33109b2832e2e63dcc7a132924ab374b ("param: use ops in struct
    kernel_param, rather than get and set fns directly").

    Use module_param_cb instead of the obsoleted module_param_call to fix a build warning.
