Subject: [Patch v4 00/16] Enable support of IOAPIC hotplug on x86 platforms
Date: Thu, 28 Aug 2014 10:22:25 +0800 [thread overview]
Message-ID: <1409192561-19744-1-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 latest mainstream kernel at
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
You may pull it from
https://github.com/jiangliu/linux.git ioapic/hotplug_v4
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!
Patch 1-5 are bugfixes and enhancements to ACPI subsystem
Patch 6-14 enhances IOAPIC core to support IOAPIC hotplug
Patch 15 killes PCI IOAPIC driver
Patch 16 reimplements ACPI IOAPIC driver and enables IOAPIC hotplug
V3->V4:
1) Fix a bug in manage IOAPIC reference count
2) Rebase to v3.17-rc2
3) Refine commit messages
V2->V3:
1) Refine ACPI resource walk functions for PCI root bus and IOAPIC
2) Improve commit messages
3) Reorder patch order for better maintenence
Jiang Liu (13):
x86, PCI, ACPI: Kill private function resource_to_addr() in
arch/x86/pci/acpi.c
ACPI: Correct return value of acpi_dev_resource_address_space()
ACPI: Fix minor syntax issues in processor_core.c
ACPI: Rename processor_core.c as apic_id.c
x86, irq: Remove __init marker for functions will be used by IOAPIC
hotplug
x86, irq: Keep balance of IOAPIC pin reference count
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 interfaces to support ACPI based IOAPIC
hot-removal
x86, irq: Introduce helper to check whether an IOAPIC has been
registered
PCI: Remove PCI ioapic driver
x86, irq, ACPI: Implement ACPI driver to support IOAPIC hotplug
Yinghai Lu (3):
ACPI: Add interfaces to parse IOAPIC ID for IOAPIC hotplug
x86, irq: Split out alloc_ioapic_save_registers()
x86, irq: Prefer assigned ID in APIC ID register for x86_64
