PCI, ACPI: remove ACPI PCI subdriver mechanism This patch set is directly derived from two sources: 1) '[PATCH 00/15] PCI/ACPI: Remove "pci_root" sub-driver support' at https://lkml.org/lkml/2012/12/7/11 from Myron Stowe The major goal is to resolve any potential sequencing inter-dependencies by converting sub-driver functionality to being only supported as statically built-in to the kernel as part of the "pci_root" driver itself. 2) 'introduce PCI bus notifier chain to get rid of the ACPI PCI subdriver' at http://lwn.net/Articles/533547/ The major goal is to update PCI slots(pci_slot), ACPI based PCI hotplug slots(acpiphp), PCIe AER(aer) etc when hot-plugging PCI devices and P2P bridges, and eventually get rid of the ACPI PCI subdriver interfaces. This patchset applies to Bjorn's pci-next branch. Patch 1-4 are minor fixups for 3.9-rc1. Patch 5-8 introduce two hooks into PCI core which will be called when creating/destroying PCI buses. Patch 9-12 replace ACPI PCI subdriver interfaces with the new hook mechanism for pci_slot and acpiphp. Patch 13 removes the ACPI PCI subdriver interfaces. v7->v8: Hook directly into the PCI core to replace pci_bus notification Remove ACPI PCI subdriver related code Jiang Liu (10): PCI: do not check is_added flag in pci_remove_bus() PCI/acpiphp: don't rely on function 0 in disable_device() ACPI/acpiphp: replace local macros with standard ACPI macros PCI: introduce platform dependent hooks for creating/destroying PCI busses PCI, ACPI: prepare stub functions to handle ACPI PCI (hotplug) slots PCI, IA64: implement pcibios_{add|remove}_bus() hooks PCI, x86: implement pcibios_{add|remove}_bus() hooks PCI, ACPI: handle PCI slot devices when creating/destroying PCI busses PCI/acpiphp: do not use ACPI PCI subdriver mechanism PCI/acpiphp: protect acpiphp data structures from concurrent updating Myron Stowe (1): PCI, ACPI: remove support of ACPI PCI subdrivers Yijing Wang (2): PCI/acpiphp: use list_for_each_entry_safe() in acpiphp_sanitize_bus() PCI/acpiphp: use normal list to simplify implementation arch/ia64/pci/pci.c | 11 + arch/x86/pci/common.c | 11 + drivers/acpi/internal.h | 5 - drivers/acpi/pci_root.c | 48 +---- drivers/acpi/pci_slot.c | 177 +++------------- drivers/acpi/scan.c | 1 - drivers/pci/bus.c | 11 +- drivers/pci/hotplug/Kconfig | 7 +- drivers/pci/hotplug/acpiphp.h | 12 +- drivers/pci/hotplug/acpiphp_core.c | 23 +- drivers/pci/hotplug/acpiphp_glue.c | 409 ++++++++++++------------------------ drivers/pci/pci-acpi.c | 30 +++ drivers/pci/probe.c | 15 +- drivers/pci/remove.c | 4 +- include/linux/acpi.h | 9 - include/linux/pci-acpi.h | 26 +++ include/linux/pci.h | 2 + 17 files changed, 268 insertions(+), 533 deletions(-) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
