Hi,

About madt_find_processor_uid() and madt_processor_handler(), my understanding is that they will find and check uid for processors based on Processor object or Device Object (ACPI0007), right?

For the Device Object (ACPI0007) case, could the codes handle the _UID implemented as Method?

  Device(XXXX) {
    Name(_HID, "ACPI0007")
    Method (_UID) {
      Return (\_SB.XXXX(XXXX, XXXX))
}
...


Table 6-189 Device Identification Objects
_UID Object that specifies a device's unique persistent ID, or a control method that generates it.


Thanks,
Star
