Subject: ACPI : Unneccessary to scan the PCI bus already scanned.
>From : Zhao Yakui <yakui.zhao@intel.com>
Maybe the desired pci bus has been already scanned. In such case it is
unnecessary to scan the pci bus with the given domain, busnum.

In struct device, we already have numa_node member. and we could use dev_to_node() /set_dev_node() to get and set numa_node in the device. set_dev_node is called in pci_device_add() with pcibus_to_node(bus). and pcibus_to_node use bus->sysdata for nodeid. the problem is when pci_add_device is called, bus->sysdata is not assigned correct nodeid yet. the result will be numa_node always is 0. pcibios_scan_root and pci_scan_root could take sysdata. So we need to get mp_bus_to_node mapping before these two are called. and get_mp_bus_to_node could get correct node for sysdata in root bus. in scanning of root bus, all child bus will take parent bus sysdata. So all pci_device->dev.numa_node will be assigned correctly automatically. later we could use dev_to_node(&pci_dev->dev) to get numa_node, and we could also could make other bus specific device get the correct numa_node too. this is one update version to pci_sysdata and jeff's pci_domain patch. and duplicated scan bus fix patch Signed-off-by: Yinghai Lu <yinghai.lu@sun.com> Index: linux-2.6/arch/x86/pci/Makefile_32 =================================================================== --- linux-2.6.orig/arch/x86/pci/Makefile_32 +++ linux-2.6/arch/x86/pci/Makefile_32 @@ -10,5 +10,6 @@ pci-y += legacy.o irq.o pci-$(CONFIG_X86_VISWS) := visws.o fixup.o pci-$(CONFIG_X86_NUMAQ) := numa.o irq.o +pci-$(CONFIG_NUMA) += mp_bus_to_node.o obj-y += $(pci-y) common.o early.o Index: linux-2.6/arch/x86/pci/common.c =================================================================== --- linux-2.6.orig/arch/x86/pci/common.c +++ linux-2.6/arch/x86/pci/common.c @@ -396,9 +396,14 @@ struct pci_bus * __devinit pcibios_scan_ return NULL;

In struct device, we already have numa_node member. and we could use dev_to_node() /set_dev_node() to get and set numa_node in the device. set_dev_node is called in pci_device_add() with pcibus_to_node(bus). and pcibus_to_node use bus->sysdata for nodeid. the problem is when pci_add_device is called, bus->sysdata is not assigned correct nodeid yet. the result will be numa_node always is 0. pcibios_scan_root and pci_scan_root could take sysdata. So we need to get mp_bus_to_node mapping before these two are called. and get_mp_bus_to_node could get correct node for sysdata in root bus. in scanning of root bus, all child bus will take parent bus sysdata. So all pci_device->dev.numa_node will be assigned correctly automatically. later we could use dev_to_node(&pci_dev->dev) to get numa_node, and we could also could make other bus specific device get the correct numa_node too. this is one update version to pci_sysdata and jeff's pci_domain patch. and duplicated scan bus fix patch Signed-off-by: Yinghai Lu <yinghai.lu@sun.com> Index: linux-2.6/arch/x86/pci/Makefile_32 =================================================================== --- linux-2.6.orig/arch/x86/pci/Makefile_32 +++ linux-2.6/arch/x86/pci/Makefile_32 @@ -10,5 +10,6 @@ pci-y += legacy.o irq.o pci-$(CONFIG_X86_VISWS) := visws.o fixup.o pci-$(CONFIG_X86_NUMAQ) := numa.o irq.o +pci-$(CONFIG_NUMA) += mp_bus_to_node.o obj-y += $(pci-y) common.o early.o Index: linux-2.6/arch/x86/pci/common.c =================================================================== --- linux-2.6.orig/arch/x86/pci/common.c +++ linux-2.6/arch/x86/pci/common.c @@ -396,9 +396,14 @@ struct pci_bus * __devinit pcibios_scan_ return NULL;

The function of pci_bios_acpi_scan_root will also return NULL pointer subsequently. In such case it will bring that acpi_pci_root driver can't be loaded. When the system works in acpi mode, there will be some potential problem if acpi_pci_root driver can't be loaded. For example: http://bugzilla.kernel.org/show_bug.cgi?id=10124 Thanks.
