127 | * Note: History of _PRW support in ACPICA |
||
128 | * |
||
129 | * Originally (2000 - 2010), the GPE initialization code performed a walk of |
||
130 | * the entire namespace to execute the _PRW methods and detect all GPEs |
||
131 | * capable of waking the system. |
||
132 | * |
||
133 | * As of 10/2010, the _PRW method execution has been removed since it is |
||
134 | * actually unnecessary. The host OS must in fact execute all _PRW methods |
||
135 | * in order to identify the device/power-resource dependencies. We now put |
||
136 | * the onus on the host OS to identify the wake GPEs as part of this process |
||
137 | * and to inform ACPICA of these GPEs via the AcpiSetupGpeForWake interface. This |
||
138 | * not only reduces the complexity of the ACPICA initialization code, but in |
||
139 | * some cases (on systems with very large namespaces) it should reduce the |
||
140 | * kernel boot time as well. |
