We're getting close to the new merge window, and I _think_ this patch series is ready for consideration. Notably: - multiple rescans/removes of devices with and without bridges - verified that resource allocation after multiple remove/rescan cycles is the same as what we had during initial boot - fixes the complete suckage of fakephp (that I created) - doesn't affect existing hotplug drivers - tested on x86 and ia64 platforms Please review, and consider testing. For testing ease, you can pull from my git branch: git://git.kernel.org/pub/scm/linux/kernel/git/achiang/pci-hotplug.git branch 'test-20090318' is what you want Note, this test branch does contain the small assorted patches in AER and the PCIe portdriver that I fixed along the way, but does not contain the sysfs callback mutex that I introduced to protect myself from Vegard Nossum. ;) If you want to hammer away at the sysfs interface, please apply this patch on top: http://thread.gmane.org/gmane.linux.kernel/806648 What I'm continuing to do: - investigate converting existing hotplug drivers to use new pci_rescan_bus() interface Thanks. /ac v3 -> v4: - protect sysfs interfaces with mutex - undo changes in pci_do_scan_bus - introduce pci_rescan_bus instead - do not initialize bridges more than once v2 -> v3: - properly remove device with internal bridge - added Kenji Kaneshige's pci_is_root_bus() interface - dropped whitespace cleanups for another time 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 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/devices/.../remove PCI: Introduce /sys/bus/pci/rescan PCI: Introduce pci_rescan_bus() PCI: do not initialize bridges more than once PCI: always scan child buses Kenji Kaneshige (1): PCI: pci_is_root_bus helper Trent Piepho (3): PCI Hotplug: restore fakephp interface with complete reimplementation 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 | 10 + drivers/pci/hotplug/fakephp.c | 443 +++++++--------------------- drivers/pci/pci-driver.c | 1 drivers/pci/pci-sysfs.c | 95 ++++++ drivers/pci/pci.h | 6 drivers/pci/probe.c | 103 ++++--- drivers/pci/setup-bus.c | 3 include/linux/pci.h | 12 + 10 files changed, 358 insertions(+), 374 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
