[PATCH v2 0/9] enhance PCI related drivers to handle hotplug events
From: Jiang Liu
Date: Fri Sep 14 2012 - 23:13:20 EST
Several PCI related drivers, such as pci_bind, pci_slot, acpiphp and
aerdrv, don't handle PCI device hotplug events, which may cause stale
state and even system crashes.
This patch set registers bus notification callbacks to update driver
states when PCI device hotplug happens.
V1->V2:
Hook pcie_port_bus_type instead of pci_bus_type for aerdrv
Jiang Liu (7):
PCI: make PCI device create/destroy logic symmetric
PCI: split registration of PCI bus devices into two stages
ACPI/pci_bind: correctly update binding relationship for PCI hotplug
ACPI/pci-bind: remove bind/unbind callbacks from acpi_device_ops
ACPI/pci_slot: update PCI slot information when PCI hotplug event
happens
PCI/acpiphp: update ACPI hotplug slot information when PCI hotplug
happens
PCI/acpiphp: serialize access to the bridge_list list
Yijing Wang (2):
PCI: preserve dev->subordinate until pci_stop_dev() has been called
PCI/AER: update AER configuration when PCI hotplug event happens
