From 514604c6d1779c55d3e97dc4e9a71c117c1ccbcd Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Thu, 7 Jul 2005 16:59:00 -0700 Subject: [IA64] pcibus_to_node implementation for IA64 pcibus_to_node provides a way for the Linux kernel to identify to which node a certain pcibus connects to. Allocations of control structures for devices can then be made on the node where the pci bus is located to allow local access during interrupt and other device manipulation. This patch provides a new "node" field in the the pci_controller structure. The node field will be set based on ACPI information (thanks to Alex Williamson Signed-off-by: Tony Luck --- include/asm-ia64/pci.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/asm-ia64/pci.h') diff --git a/include/asm-ia64/pci.h b/include/asm-ia64/pci.h index 0c4c5d801d3..8b7237cc84c 100644 --- a/include/asm-ia64/pci.h +++ b/include/asm-ia64/pci.h @@ -128,6 +128,7 @@ struct pci_controller { void *acpi_handle; void *iommu; int segment; + int node; /* nearest node with memory or -1 for global allocation */ unsigned int windows; struct pci_window *window; -- cgit v1.2.3
