Yep, this is a known PCI problem, at least if you're referring to the fact that pci_fixup_irqs() only happens for devices present at boot-time. I would love for somebody to fix that generically. I would also like to squash together the PCI, PCIe, and PCI hotplug Kconfig options so arches would only have to include drivers/pci/Kconfig. > This has been tested on a Marvell 88F6281 with a TI XIO3130 > PCIe bridge (with hotplug enabled) and fixes for IRQ assignment > added. > > Signed-off-by: Ben Dooks <ben.dooks@xxxxxxxxxxxxxxx> I assume this will be handled via an ARM tree, but if you want it: Acked-by: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> > -- > CC: Linux ARM Kernel list <linux-arm-kernel@xxxxxxxxxxxxxxxxxxx> > CC: Russell King <linux@xxxxxxxxxxxxxxxx> > CC: Linux Kernel Mailing List <linux-kernel@xxxxxxxxxxxxxxx> > CC: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> > CC: Linux PCI List <linux-pci@xxxxxxxxxxxxxxx> > --- > arch/arm/Kconfig | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig > index 9f1f09a..4574ab4 100644 > --- a/arch/arm/Kconfig > +++ b/arch/arm/Kconfig > @@ -1302,6 +1302,7 @@ config PCI_HOST_ITE8152 > select DMABOUNCE > > source "drivers/pci/Kconfig" > +source "drivers/pci/hotplug/Kconfig" > source "drivers/pci/pcie/Kconfig" > > source "drivers/pcmcia/Kconfig" > -- > 2.1.4 > -- 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
