It will be great to get rid of some of those weak functions! Bjorn ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
[PATCH v1 00/21] Use MSI chip to configure MSI/MSI-X in all platforms
This series is based Bjorn's pci-next branch + Alexander Gordeev's two patches "Remove arch_msi_check_device()" link: https://lkml.org/lkml/2014/7/12/41 Currently, there are a lot of weak arch functions in MSI code. Thierry Reding Introduced MSI chip framework to configure MSI/MSI-X in arm. This series use MSI chip framework to refactor MSI code across all platforms to eliminate weak arch functions. It has been tested fine in x86(with or without irq remap). RFC->v1: Updated "[patch 4/21] x86/xen/MSI: Eliminate...", export msi_chip instead of #ifdef to fix MSI bug in xen running in x86. Rename arch_get_match_msi_chip() to arch_find_msi_chip(). Drop use struct device as the msi_chip argument, we will do that later in another patchset. Yijing Wang (21): PCI/MSI: Clean up struct msi_chip argument PCI/MSI: Remove useless bus->msi assignment MSI: Remove the redundant irq_set_chip_data() x86/xen/MSI: Eliminate arch_msix_mask_irq() and arch_msi_mask_irq() PCI/MSI: Introduce weak arch_find_msi_chip() to find MSI chip PCI/MSI: Refactor struct msi_chip to make it become more common x86/MSI: Use MSI chip framework to configure MSI/MSI-X irq x86/xen/MSI: Use MSI chip framework to configure MSI/MSI-X irq Irq_remapping/MSI: Use MSI chip framework to configure MSI/MSI-X irq x86/MSI: Remove unused MSI weak arch functions MIPS/Octeon/MSI: Use MSI chip framework to configure MSI/MSI-X irq MIPS/Xlp: Remove the dead function destroy_irq() to fix build error MIPS/Xlp/MSI: Use MSI chip framework to configure MSI/MSI-X irq MIPS/Xlr/MSI: Use MSI chip framework to configure MSI/MSI-X irq Powerpc/MSI: Use MSI chip framework to configure MSI/MSI-X irq s390/MSI: Use MSI chip framework to configure MSI/MSI-X irq arm/iop13xx/MSI: Use MSI chip framework to configure MSI/MSI-X irq IA64/MSI: Use MSI chip framework to configure MSI/MSI-X irq Sparc/MSI: Use MSI chip framework to configure MSI/MSI-X irq tile/MSI: Use MSI chip framework to configure MSI/MSI-X irq PCI/MSI: Clean up unused MSI arch functions arch/arm/mach-iop13xx/include/mach/pci.h |2 + arch/arm/mach-iop13xx/iq81340mc.c|1 + arch/arm/mach-iop13xx/iq81340sc.c|1 + arch/arm/mach-iop13xx/msi.c |9 ++- arch/arm/mach-iop13xx/pci.c |6 ++ arch/ia64/kernel/msi_ia64.c | 18 - arch/mips/pci/msi-octeon.c | 35 +--- arch/mips/pci/msi-xlp.c | 18 +++- arch/mips/pci/pci-xlr.c | 15 +++- arch/powerpc/kernel/msi.c| 14 +++- arch/s390/pci/pci.c | 18 - arch/sparc/kernel/pci.c | 14 +++- arch/tile/kernel/pci_gx.c| 14 +++- arch/x86/include/asm/apic.h |4 + arch/x86/include/asm/pci.h |4 +- arch/x86/include/asm/x86_init.h |7 -- arch/x86/kernel/apic/io_apic.c | 16 - arch/x86/kernel/x86_init.c | 34 arch/x86/pci/xen.c | 60 +-- drivers/iommu/irq_remapping.c|9 ++- drivers/irqchip/irq-armada-370-xp.c | 12 +-- drivers/pci/host/pci-tegra.c |8 +- drivers/pci/host/pcie-designware.c |4 +- drivers/pci/host/pcie-rcar.c |8 +- drivers/pci/msi.c| 123 +- drivers/pci/probe.c |1 - include/linux/msi.h | 26 ++- 27 files changed, 268 insertions(+), 213 deletions(-) ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
