From a79e4198d1effbba040e9bf407a95fc9b3418789 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Thu, 11 Oct 2007 16:58:30 -0400 Subject: PCI: X86: Introduce and enable PCI domain support * fix bug in pci_read() and pci_write() which prevented PCI domain support from working (hardcoded domain 0). * unconditionally enable CONFIG_PCI_DOMAINS * implement pci_domain_nr() and pci_proc_domain(), as required of all arches when CONFIG_PCI_DOMAINS is enabled. * store domain in struct pci_sysdata, as assigned by ACPI * support "pci=nodomains" Signed-off-by: Jeff Garzik Cc: Andi Kleen Signed-off-by: Greg Kroah-Hartman --- arch/x86/pci/common.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'arch/x86/pci/common.c') diff --git a/arch/x86/pci/common.c b/arch/x86/pci/common.c index 7d6a9a5..2d71bbc 100644 --- a/arch/x86/pci/common.c +++ b/arch/x86/pci/common.c @@ -29,12 +29,14 @@ struct pci_raw_ops *raw_pci_ops; static int pci_read(struct pci_bus *bus, unsigned int devfn, int where, int size, u32 *value) { - return raw_pci_ops->read(0, bus->number, devfn, where, size, value); + return raw_pci_ops->read(pci_domain_nr(bus), bus->number, + devfn, where, size, value); } static int pci_write(struct pci_bus *bus, unsigned int devfn, int where, int size, u32 value) { - return raw_pci_ops->write(0, bus->number, devfn, where, size, value); + return raw_pci_ops->write(pci_domain_nr(bus), bus->number, + devfn, where, size, value); } struct pci_ops pci_root_ops = { -- cgit v1.1
