Subject: [PATCH V2 0/6] PCI, x86: update MMCFG information when hot-plugging PCI host bridges
Date: Tue, 10 Apr 2012 00:22:42 +0800 [thread overview]
Message-ID: <1333988568-11282-1-git-send-email-jiang.liu@huawei.com> (raw)
This patchset enhance pci_root driver to update MMCFG information when
hot-plugging PCI root bridges. It applies to Yinghai's tree at
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-root-bus-hotplug
The second patch is based on Taku Izumi work with some enhancements to
correctly handle PCI host bridges without _CBA method.
v2: split into smaller patches and skip updating MMCFG information when
MMCFG is disabled
Jiang Liu (6):
PCI, x86: split out pci_mmcfg_check_reserved() for code reuse
PCI, x86: split out pci_mmconfig_alloc() for code reuse
PCI, x86: use RCU list to protect mmconfig list
PCI, x86: introduce pci_mmcfg_arch_map()/pci_mmcfg_arch_unmap()
PCI, x86: introduce pci_mmconfig_insert()/delete() for PCI root
bridge hotplug
PCI, ACPI, x86: update MMCFG information when hot-plugging PCI host
bridges
