This patch set enhances IOAPIC core and ACPI drivers to support IOAPIC hotplug on x86 platforms. It's based on another patch set "use irqdomain to dynamically allocate IRQ for IOAPIC" at https://lkml.org/lkml/2014/6/9/44 You may pull it from https://github.com/jiangliu/linux.git ioapic/hotplug_v2 We have pick up several patches from Yinghai's original IOAPIC hotplug patch set and reimplemented IOAPIC driver as an ACPI driver instead of a PCI driver. It has been tested on a 4-socket Intel SDV with socket hot-addition capability. Any suggestions are welcomed! Jiang Liu (10): x86, irq, ACPI: protect acpi_pci_irq_enable() from reentrance PCI: kill wrong warning message in pcieport driver x86, irq: remove __init marker for functions will be used by IOAPIC hotplug x86, irq: refine mp_register_ioapic() to prepare for IOAPIC hotplug x86, irq, ACPI: introduce a rwsem to protect IOAPIC operations from hotplug x86, irq, ACPI: implement interface to support ACPI based IOAPIC hot-addition x86, irq, ACPI: implement interface to support ACPI based IOAPIC hot-removal x86, irq: introduce helper to check whether an IOAPIC has been registered pci, ioapic: kill ioapic PCI driver x86, irq, ACPI: implement ACPI driver to support IOAPIC hotplug Yinghai Lu (6): x86, irq: Split out alloc_ioapic_save_registers() x86, ioapic: Find usable ioapic id for 64bit. ACPI, x86/PCI: Move resource_to_addr() to acpi generic ACPI: Make map_mat_entry handle x2apic entry ACPI: Move acpi_get_cpuid() to separated file ACPI, ioapic: Add acpi_get_ioapic_id() arch/x86/include/asm/io_apic.h | 6 +- arch/x86/kernel/acpi/boot.c | 74 +++++++++- arch/x86/kernel/apic/io_apic.c | 235 +++++++++++++++++++++++++------- arch/x86/pci/acpi.c | 50 +------ drivers/acpi/Kconfig | 6 + drivers/acpi/Makefile | 2 + drivers/acpi/apic_id.c | 295 ++++++++++++++++++++++++++++++++++++++++ drivers/acpi/internal.h | 7 + drivers/acpi/ioapic.c | 231 +++++++++++++++++++++++++++++++ drivers/acpi/pci_irq.c | 7 +- drivers/acpi/pci_root.c | 3 + drivers/acpi/processor_core.c | 191 -------------------------- drivers/acpi/resource.c | 46 +++++++ drivers/pci/Kconfig | 7 - drivers/pci/Makefile | 2 - drivers/pci/ioapic.c | 121 ---------------- drivers/pci/pcie/portdrv_pci.c | 4 - include/acpi/processor.h | 3 - include/linux/acpi.h | 11 ++ 19 files changed, 868 insertions(+), 433 deletions(-) create mode 100644 drivers/acpi/apic_id.c create mode 100644 drivers/acpi/ioapic.c delete mode 100644 drivers/pci/ioapic.c -- 1.7.10.4 -- 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
