It's based on another patch set "use irqdomain to dynamically allocate IRQ for IOAPIC" at https://lkml.org/lkml/2014/5/27/86 You may pull from https://github.com/jiangliu/linux.git ioapic/hotplug Once passed review, we will use Yinghai's patches to glue IOAPIC driver and ACPI PCI root driver to handle hotplug events. Jiang Liu (4): 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 arch/x86/include/asm/io_apic.h | 5 +- arch/x86/kernel/acpi/boot.c | 44 +++++++-- arch/x86/kernel/apic/io_apic.c | 207 ++++++++++++++++++++++++++++++---------- 3 files changed, 196 insertions(+), 60 deletions(-) -- 1.7.10.4
