    Subject[RFC PATCH v2 00/12] PCI core learns hotplug
    Date
    Hi all,

    Jesse asked me to send out some updated bits on this series to get
    more early review. He notes that there is at least one patch out there
    (Yuji Shimada's memory resource alignment) that would really like this.

    Original discussion here:

    http://thread.gmane.org/gmane.linux.kernel.pci/2914

    This is still a work-in-progress.

    Known to work:
    - remove any device in PCI tree once, rescan to get it back
    - device seems to be functional. :)
    - can repeat above multiple times on non PCIe machines

    Known to not work:
    - can't remove/rescan multiple times when PCIe port driver is loaded
    - hotplug drivers using pci_do_scan_bus may blow up

    TODO:
    - fix known PCIe port driver bug
    - clean up hotplug drivers using pci_do_scan_bus
    - incorporate one more of Trent's patches, will probably replace
    "Introduce /sys/bus/pci/rescan" since his implementation was nicer
    - remove ASPM patch once jbarnes's linux-next tree gets rebased ;)

    Comments welcom.

    Thanks.

    /ac

    v1 -> v2:
    - incorporated lots of Trent Piepho's work
    - beefed up pci_do_scan_bus as heavy lifter for rescanning
    - small bugfixes folded into earlier patches to get everything working
    ---

    Alex Chiang (8):
    PCI: more whitespace cleanups
    PCI Hotplug: schedule fakephp for feature removal
    PCI Hotplug: rename legacy_fakephp to fakephp
    PCI: Introduce /sys/bus/pci/devices/.../rescan
    PCI: Introduce /sys/bus/pci/rescan
    PCI: beef up pci_do_scan_bus()
    PCI: properly clean up ASPM link state on device remove
    PCI: always scan child buses

    Trent Piepho (4):
    PCI Hotplug: restore fakephp interface with complete reimplementation
    PCI: Introduce /sys/bus/pci/devices/.../remove
    PCI: pci_scan_slot() returns newly found devices
    PCI: don't scan existing devices
