[PATCH] acpiphp: Scan slots under the nested P2P bridge
Current ACPIPHP driver scans only slots under the top level PCI-to-PCI bridge. So hotplug PCI slots under the nested PCI-to-PCI bridge would not be detected. For example, if the system has the ACPI namespace like below, hotplug slots woule not be detected. Device (PCI0) { /* Root bridge */ Name (_HID, "PNP0A03") Device (P2PA) { /* PCI-to-PCI bridge */ Name (_ADR, ...) Device (P2PB) { /* PCI-to-PCI bridge */ Name (_ADR, ...) Device (S0F0) { /* hotplug slot */ Name (_ADR, ...) Name (_SUN, ...) Method (_EJ0, ...) { ... } } ... Device (S0F7) { /* hotplug slot */ Name (_ADR, ...) Name (_SUN, ...) Method (_EJ0, ...) { ... } } Device (S1F0) { /* hotplug slot */ Name (_ADR, ...) Name (_SUN, ...) Method (_EJ0, ...) { ... } } ... } } } This patch fixes this issue.
