will add pci_stop_and_remove_bus() to support remove bus in /sys/devices/pci.../pci_bus/... it support pci root bus removal. To rescan root, need to echo 1 > /sys/bus/pci/rescan_root this patcheset include some IOMM and dmar and pnpacpi fix with device refcount leaking. The patches need to apply to pci/for-linus and pci/linux-next and [PATCH 00/36] PCI: pci_host_bridge related cleanup and busn_alloc could get from git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-root-bus-hotplug Thanks Yinghai Yinghai Lu (23): PCI, sys: Use device_type and attr_groups with pci dev PCI, sysfs: create rescan_bridge under /sys/.../pci/devices/... for pci bridges PCI: Add pci_bus_add_single_device() PCI: make pci_rescan_bus_bridge_resize use pci_scan_bridge instead PCI: clean up rescan_bus_bridge_resize PCI: rescan with bus or bridge using callback method too pci, dmar: Update dmar units devices list during hotplug PNPACPI: Fix device ref leaking in acpi_pnp_match IOMMU: Fix tboot force iommu logic PCI, x86: Fix non acpi path pci_sysdata leaking with release_fn PCI: separate out pci_assign_unassigned_bus_resources() PCI: Move back pci_rescan_bus() PCI: move pci_stop_and_remove_behind_bridge down PCI: add __pci_remove_bus_devices() PCI: add pci_stop_and_remove_bus() PCI: add pci bus removal through /sys/.../pci_bus/.../remove PCI, ACPI: make acpi_pci_root_remove remove pci root bus too PCI, ACPI: add acpi_pci_root_rescan() PCI: add /sys/bus/pci/rescan_root PCI: add __pci_scan_root_bus() that can skip bus_add x86, PCI: add __pci_scan_root_bus_on_node() that can skip bus_add x86, PCI: add __pcibios_scan_specific_bus that can skip bus_add x86, PCI: add pcibios_root_rescan Documentation/ABI/testing/sysfs-bus-pci | 27 +++++ arch/x86/include/asm/pci.h | 2 + arch/x86/pci/common.c | 28 +++-- arch/x86/pci/legacy.c | 44 ++++++- drivers/acpi/pci_root.c | 66 +++++++++++ drivers/iommu/intel-iommu.c | 193 ++++++++++++++++++++++++++++-- drivers/pci/bus.c | 39 ++++++ drivers/pci/pci-sysfs.c | 137 ++++++++++++++++++++-- drivers/pci/pci.h | 1 + drivers/pci/probe.c | 43 ++++++- drivers/pci/remove.c | 77 ++++++++----- drivers/pci/setup-bus.c | 20 +--- drivers/pnp/pnpacpi/core.c | 7 +- include/linux/dmar.h | 4 + include/linux/pci.h | 6 + 15 files changed, 604 insertions(+), 90 deletions(-) -- 1.7.7 -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
