da50337373c90c Lin Ming 2010-12-13 21 * Originally (2000 - 2010), the GPE initialization code performed a walk of
da50337373c90c Lin Ming 2010-12-13 22 * the entire namespace to execute the _PRW methods and detect all GPEs
da50337373c90c Lin Ming 2010-12-13 23 * capable of waking the system.
da50337373c90c Lin Ming 2010-12-13 24 *
da50337373c90c Lin Ming 2010-12-13 25 * As of 10/2010, the _PRW method execution has been removed since it is
da50337373c90c Lin Ming 2010-12-13 26 * actually unnecessary. The host OS must in fact execute all _PRW methods
da50337373c90c Lin Ming 2010-12-13 27 * in order to identify the device/power-resource dependencies. We now put
da50337373c90c Lin Ming 2010-12-13 28 * the onus on the host OS to identify the wake GPEs as part of this process
da50337373c90c Lin Ming 2010-12-13 29 * and to inform ACPICA of these GPEs via the acpi_setup_gpe_for_wake interface. This
da50337373c90c Lin Ming 2010-12-13 30 * not only reduces the complexity of the ACPICA initialization code, but in
da50337373c90c Lin Ming 2010-12-13 31 * some cases (on systems with very large namespaces) it should reduce the
da50337373c90c Lin Ming 2010-12-13 32 * kernel boot time as well.
