Subject: [RFC Patch V1 0/4] enhance IOAPIC core to support hotplug
Date: Tue, 27 May 2014 16:24:33 +0800 [thread overview]
Message-ID: <1401179077-2020-1-git-send-email-jiang.liu@linux.intel.com> (raw)
This patch set enhances IOAPIC core 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/2014/5/27/86
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
