NAME

6       add_active_range - Register a range of PFNs backed by physical memory
7

SYNOPSIS

9       void add_active_range(unsigned int nid, unsigned long start_pfn,
10                             unsigned long end_pfn);
11

ARGUMENTS

13       nid
14           The node ID the range resides on
15
16       start_pfn
17           The start PFN of the available physical memory
18
19       end_pfn
20           The end PFN of the available physical memory
21

DESCRIPTION

23       These ranges are stored in an early_node_map[] and later used by
24       free_area_init_nodes to calculate zone sizes and holes. If the range
25       spans a memory hole, it is up to the architecture to ensure the memory
26       is not freed by the bootmem allocator. If possible the range being
27       registered will be merged with existing ranges.
