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 Documentation/ABI/testing/sysfs-bus-pci | 27 ++ Documentation/feature-removal-schedule.txt | 32 ++ Documentation/filesystems/sysfs-pci.txt | 9 + drivers/pci/hotplug-pci.c | 16 + drivers/pci/hotplug/fakephp.c | 443 +++++++--------------------- drivers/pci/pci-sysfs.c | 96 +++++- drivers/pci/pcie/aspm.c | 4 drivers/pci/probe.c | 90 +++--- drivers/pci/remove.c | 4 9 files changed, 323 insertions(+), 398 deletions(-) -- 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
