Add a per node state sysfs class attribute file to /sys/devices/system/node to display node state masks. E.g., on a 4-cell HP ia64 NUMA platform, we have 5 nodes: 4 representing the actual hardware cells and one memory-only pseudo-node representing a small amount [512MB] of "hardware interleaved" memory. With this patch, in /sys/devices/system/node we see: #ls -1F /sys/devices/system/node has_cpu has_normal_memory node0/ node1/ node2/ node3/ node4/ online possible #cat /sys/devices/system/node/possible 0-255 #cat /sys/devices/system/node/online 0-4 #cat /sys/devices/system/node/has_normal_memory 0-4 #cat /sys/devices/system/node/has_cpu 0-3 Signed-off-by: Lee Schermerhorn <lee.schermerhorn@hp.com> Acked-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
