Subject: [RFC Patch V2 00/16] Enable support of IOAPIC hotplug on x86 platforms
Date: Tue, 17 Jun 2014 13:29:39 +0800 [thread overview]
Message-ID: <1402982995-13747-1-git-send-email-jiang.liu@linux.intel.com> (raw)
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()
