Subject: [PATCH v7 00/10] PCI, x86: update MMCFG information when hot-plugging PCI host bridges
Date: Sat, 26 May 2012 17:53:53 +0800 [thread overview]
Message-ID: <1338026043-3968-1-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
git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git pci/next-3.5
-v2: split into smaller patches and skip updating MMCFG information when
MMCFG is disabled
-v3: add mmconf_added to simply free path, also make pci_mmconfig_insert()
to process extra exist case --- By Yinghai
-v4: tune arch_acpi_pci_root_add() to handle a corner case raised by Kenji
-v5: address review comments from Bjorn and Taku, also better handle corner
cases in arch_acpi_pci_root_add()
-v6: get rid of arch_acpi_pci_root_xxx() by using existing hooks
add MCFG information for host bridges on demand
more corner cases clear up
correctly handle condition compilation
fix section mismatch issues
fix a issue reported by Taku about a BIOS bug
-v7: unify log messages
remove redundant host bridge resource related log messages
fix a issue reported by Taku which breaks pnp resource allocation
