Signed-off-by: Matthew Minter <matt@xxxxxxxxxxxx> pci_fixup_irqs is the current method used in most arches to assign IRQs to PCI devices. This has a number of flaws including it requiring an extra walk of the PCI bus and most importantly not running for devices which are added after boot time, this includes hot-added devices on boards that support this. This patch set modifies the IRQ mapping and swizzling infrastructure such that functions are registered by the boot code (instead of being run directly by the boot code) and then run later in the enable_device path such that it will apply to all devices and not only those inserted at boot time. This is cleaner as it unifies how each architecture allocates PCI IRQs as much as possible (some arches were particularly resistant to these changes so some work-arounds have been used or the change disabled completely). The caveat here is that I have been forced to modify some architecture specific code for various architectures which I cannot test due to not having such boards available. The code seems correct and the changes in most cases are small and trivial however I have not tested all the patches for rare arches. NEW: Since the last version all changes and suggested bug fixes have been implemented the patch-set has also been rebased onto the latest kernel version to ease merging. Many Thanks, Matthew Note also that I have switched email addresses due to a change in employment but I am indeed the same person who submitted the previous versions of this patch. arch/alpha/kernel/pci.c | 16 +++--- arch/alpha/kernel/sys_nautilus.c | 1 - arch/arm/kernel/bios32.c | 13 +++-- arch/cris/arch-v32/drivers/pci/bios.c | 14 ++--- arch/frv/mb93090-mb00/pci-frv.h | 1 - arch/frv/mb93090-mb00/pci-irq.c | 28 ++++++---- arch/frv/mb93090-mb00/pci-vdk.c | 1 - arch/ia64/pci/pci.c | 3 ++ arch/m68k/platform/coldfire/pci.c | 8 ++- arch/microblaze/pci/pci-common.c | 10 ++-- arch/mips/pci/pci.c | 9 +++- arch/mn10300/unit-asb2305/pci-asb2305.h | 5 +- arch/mn10300/unit-asb2305/pci-irq.c | 25 ++------- arch/mn10300/unit-asb2305/pci.c | 21 +++----- arch/parisc/kernel/pci.c | 8 ++- arch/powerpc/kernel/pci-common.c | 26 ++++----- arch/s390/pci/pci.c | 7 +++ arch/sh/drivers/pci/fixups-cayman.c | 2 +- arch/sh/drivers/pci/fixups-dreamcast.c | 2 +- arch/sh/drivers/pci/fixups-r7780rp.c | 2 +- arch/sh/drivers/pci/fixups-rts7751r2d.c | 6 +-- arch/sh/drivers/pci/fixups-sdk7780.c | 4 +- arch/sh/drivers/pci/fixups-se7751.c | 2 +- arch/sh/drivers/pci/fixups-sh03.c | 2 +- arch/sh/drivers/pci/fixups-snapgear.c | 2 +- arch/sh/drivers/pci/fixups-titan.c | 4 +- arch/sh/drivers/pci/pci.c | 10 ++-- arch/sh/drivers/pci/pcie-sh7786.c | 2 +- arch/sparc/kernel/leon_pci.c | 12 ++++- arch/sparc/kernel/pci.c | 21 ++++++-- arch/tile/kernel/pci.c | 10 ++-- arch/tile/kernel/pci_gx.c | 10 ++-- arch/unicore32/kernel/pci.c | 11 ++-- arch/x86/include/asm/pci_x86.h | 7 +-- arch/x86/kernel/x86_init.c | 1 - arch/x86/pci/acpi.c | 5 +- arch/x86/pci/common.c | 2 - arch/x86/pci/irq.c | 94 ++++++++++++++++++--------------- drivers/of/of_pci_irq.c | 2 +- drivers/pci/Makefile | 15 +----- drivers/pci/host-bridge.c | 2 +- drivers/pci/pci.c | 5 +- drivers/pci/pci.h | 1 + drivers/pci/probe.c | 12 ----- drivers/pci/setup-irq.c | 34 ++++++------ include/linux/pci.h | 6 ++- 46 files changed, 265 insertions(+), 219 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
