ACPICA: Major update for acpi_get_object_info external interface
Completed a major update for the acpi_get_object_info external interface.
Changes include:
- Support for variable, unlimited length HID, UID, and CID strings
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- Call the _SxW power methods on behalf of a device object
- Determine if a device is a PCI root bridge
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.
Also, update all invocations of acpi_get_object_info interface
