State of the Linux PCI Subsystem for 2.6.23-rc8
Here's a summary of the current state of the Linux PCI subsystem, as of 2.6.23-rc8. If the information in here is incorrect, or anyone knows of any outstanding issues not listed here, please let me know. List of outstanding regressions from 2.6.22: - none known. List of outstanding regressions from older kernel versions: - none known. If interested, the list of all currently open PCI bugs can be seen at: http://bugzilla.kernel.org/showdependencytree.cgi?id=5829&hide_resolved=1 Future patches that are currently in my quilt tree (as found at http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/ ) for the PCI subsystem are as follows. All of these will be submitted for inclusion into 2.6.24, except as noted. The diffstat of these patches is included at the bottom of this message for those that are interested. - various pci quirks for different devices - pci hotplug driver kthread conversion - pci hotplug bugfixes - pci express hotplug tweaks and fixes - minor bugfixes and cleanups - MSI documentation update - pci bridge device rework. Note, this was reported to break Andrew's x86-64 box, but he lost the picture he took of the oops. Others reported that it worked just fine on their boxes. I'm still a little hesitant of sending this to 2.6.24 until I can track down what happened here. There are no PCI api changes scheduled for 2.6.24. thanks, greg k-h Diffstat of the current pci-2.6 quilt queue: Documentation/DMA-API.txt |3 Documentation/MSI-HOWTO.txt | 69 arch/i386/kernel/pci-dma.c|3 arch/i386/kernel/reboot_fixups.c |6 + arch/i386/pci/common.c| 10 + arch/i386/pci/fixup.c | 47 arch/i386/pci/irq.c | 39 +++ arch/x86_64/kernel/pci-dma.c |1 drivers/pci/bus.c | 17 ++- drivers/pci/hotplug/cpqphp_core.c |2 drivers/pci/hotplug/cpqphp_ctrl.c | 74 - drivers/pci/hotplug/ibmphp_hpc.c | 57 ++ drivers/pci/hotplug/pciehp_core.c | 24 +--- drivers/pci/hotplug/pciehp_ctrl.c | 20 +-- drivers/pci/hotplug/pciehp_hpc.c | 209 ++ drivers/pci/hotplug/pciehp_pci.c | 24 ++-- drivers/pci/pci-driver.c |3 drivers/pci/pci.c |5 drivers/pci/pci.h |2 drivers/pci/pcie/Kconfig |9 - drivers/pci/probe.c | 82 +++--- drivers/pci/quirks.c | 43 --- drivers/pci/remove.c |6 - include/linux/pci.h |4 include/linux/pci_ids.h |3 include/linux/pci_regs.h |6 - lib/swiotlb.c |1 27 files changed, 316 insertions(+), 453 deletions(-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

That's not a regression, right? Tt's probably never worked for that kind of box :) I think the pci bus patches that are pending from Jeff Garzik should fix up these issues. They are in one of his trees, and in the -mm release, if you are able to test those. thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

I'll take it, as I guess it should go through me, Andi is going to have enough merge issues for 2.6.24 :) I'll add them to my tree later today. > As I recall, some NUMA folks hacked in my damage (storing numa node in > x86's new struct pci_sysdata), noted and fixed additional fallout, and > added their own damage for good measure :) Yeah, I don't really trust all of the pci numa things as it keeps blowing up in odd ways, and we seem to be doing a lot of extra work for the 2 NUMA-CUBE users in the whole world... thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Please don't pull 'pciseg' just yet... it needs the fixes Andi pointed out, namely, it should be turned on by default in x86 / x86-64 platform Kconfig, and have a boot-time method of disabling it.

Ok, let me know when you want me to pull it and I will. Or just send me the patches by email, that's much easier for me :) thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
