Specifically I'm trying to identify what pci bus, device and function is associated with a acpi device under the pci root bridge (PCI0)
For example.
I have
P0P2.BMD0.BPD0
P0P2.BMD0.BPD1
P0P2.BMD0.BPD2
POP2 disassembles as follows on my test box...I understand this is a PCI bridge but what standard tells me that this is in fact a pci bridge other than the name?
I understand that the _ADR tells me that the device is 2.
Code: Select all
Device (P0P2)
{
Name (_ADR, 0x00020000)
OperationRegion (PMER, PCI_Config, 0x00, 0xFF)
Field (PMER, DWordAcc, Lock, Preserve)
{
Offset (0x48),
, 9,
PMGE, 1,
Offset (0x8C),
Offset (0x8E),
PMST, 1
}
Name (_PRW, Package (0x02)
{
0x09,
0x05
})
Method (_PRT, 0, NotSerialized)
.... and so on
Code: Select all
Device (BMD0)
{
Name (_ADR, 0x00)
Method (_PRT, 0, NotSerialized)
{
....
From what I can tell the _ADR represents the device id again on the pci bus.
Code: Select all
Device (BPD1)
{
Name (_ADR, 0x00010000)
Name (_PRW, Package (0x02)
{
0x09,
0x05
})
....
