BNUM numbering changes across DSDT due to addition of new bridges.
Fixed missing PCI tree brunch (q35/DSDT.multi-bridge case):
// -device pcie-root-port,id=rpnohp,chassis=8,addr=0xA.0,hotplug=off
+ Device (S50)
+ {
+ Name (_ADR, 0x000A0000) // _ADR: Address
// -device pcie-root-port,id=rp3,chassis=9,bus=rpnohp
+ Device (S00)
+ {
+ Name (_ADR, Zero) // _ADR: Address
+ Name (BSEL, Zero)
+ Device (S00)
+ {
+ Name (_ADR, Zero) // _ADR: Address
+ Name (ASUN, Zero)
+ Method (_DSM, 4, Serialized) // _DSM: Device-Specific Method
+ {
+ Local0 = Package (0x02)
+ {
+ BSEL,
+ ASUN
+ }
+ Return (PDSM (Arg0, Arg1, Arg2, Arg3, Local0))
+ }
+
+ Name (_SUN, Zero) // _SUN: Slot User Number
+ Method (_EJ0, 1, NotSerialized) // _EJx: Eject Device
+ {
+ PCEJ (BSEL, _SUN)
+ }
+ }
+
+ Method (DVNT, 2, NotSerialized)
+ {
+ If ((Arg0 & One))
+ {
+ Notify (S00, Arg1)
+ }
+ }
+ }
+ }
Fixed hotplug notification for leaf root port (hotplug=on) attached to
intermediate root port (hotplug=off) (q35/DSDT.multi-bridge case)
// -device pcie-root-port,id=rpnohp,chassis=8,addr=0xA.0,hotplug=off
+ Scope (S50)
+ {
// -device pcie-root-port,id=rp3,chassis=9,bus=rpnohp
+ Scope (S00)
+ {
+ Method (PCNT, 0, NotSerialized)
+ {
+ BNUM = Zero
+ DVNT (PCIU, One)
+ DVNT (PCID, 0x03)
+ }
+ }
+
+ Method (PCNT, 0, NotSerialized)
+ {
+ ^S00.PCNT ()
+ }
+ }
...
Method (PCNT, 0, NotSerialized)
{
+ ^S50.PCNT ()
^S13.PCNT ()
Populated slots being described on coldplugged bridges even if
ACPI bridge hotplug is disabled.
(pc/DSDT.hpbridge and pc/DSDT.hpbrroot)
...
Device (S18)
{
Name (_ADR, 0x00030000) // _ADR: Address
+ Device (S08)
+ {
+ Name (_ADR, 0x00010000) // _ADR: Address
+ }
+
+ Device (S10)
+ {
+ Name (_ADR, 0x00020000) // _ADR: Address
+ }
}
...
Device (S18)
{
Name (_ADR, 0x00030000) // _ADR: Address
+ Device (S00)
+ {
+ Name (_ADR, Zero) // _ADR: Address
+ }
}
