GET_PFN_RANGE_FOR_NI(9) 				    Memory Management in Linux					   GET_PFN_RANGE_FOR_NI(9)

NAME

       get_pfn_range_for_nid - Return the start and end page frames for a node

SYNOPSIS

       void __meminit get_pfn_range_for_nid(unsigned int nid, unsigned long * start_pfn, unsigned long * end_pfn);

ARGUMENTS

       nid
	   The nid to return the range for. If MAX_NUMNODES, the min and max PFN are returned.

       start_pfn
	   Passed by reference. On return, it will have the node start_pfn.

       end_pfn
	   Passed by reference. On return, it will have the node end_pfn.

DESCRIPTION

       It returns the start and end page frame of a node based on information provided by an arch calling add_active_range. If called for a node
       with no available memory, a warning is printed and the start and end PFNs will be 0.

Detailed Description
Function Documentation
   static inline int hwloc_cpuset_from_linux_libnuma_ulongs (hwloc_topology_ttopology, hwloc_cpuset_tcpuset, const unsigned long *mask, unsigned
       longmaxnode) [static]
       Convert the array of unsigned long mask into hwloc CPU set. mask is a array of unsigned long that will be read. maxnode contains the
       maximal node number that may be read in mask.

       This function may be used after calling get_mempolicy or any other function that takes an array of unsigned long as output parameter (and
       possibly a maximal node number as input parameter).

   static inline int hwloc_cpuset_to_linux_libnuma_ulongs (hwloc_topology_ttopology, hwloc_const_cpuset_tcpuset, unsigned long *mask, unsigned
       long *maxnode) [static]
       Convert hwloc CPU set cpuset into the array of unsigned long mask. mask is the array of unsigned long that will be filled. maxnode contains
       the maximal node number that may be stored in mask. maxnode will be set to the maximal node number that was found, plus one.

       This function may be used before calling set_mempolicy, mbind, migrate_pages or any other function that takes an array of unsigned long and
       a maximal node number as input parameter.

   static inline int hwloc_nodeset_from_linux_libnuma_ulongs (hwloc_topology_ttopology, hwloc_nodeset_tnodeset, const unsigned long *mask,
       unsigned longmaxnode) [static]
       Convert the array of unsigned long mask into hwloc NUMA node set. mask is a array of unsigned long that will be read. maxnode contains the
       maximal node number that may be read in mask.

       This function may be used after calling get_mempolicy or any other function that takes an array of unsigned long as output parameter (and
       possibly a maximal node number as input parameter).

   static inline int hwloc_nodeset_to_linux_libnuma_ulongs (hwloc_topology_ttopology, hwloc_const_nodeset_tnodeset, unsigned long *mask, unsigned
       long *maxnode) [static]
       Convert hwloc NUMA node set nodeset into the array of unsigned long mask. mask is the array of unsigned long that will be filled. maxnode
       contains the maximal node number that may be stored in mask. maxnode will be set to the maximal node number that was found, plus one.

       This function may be used before calling set_mempolicy, mbind, migrate_pages or any other function that takes an array of unsigned long and
       a maximal node number as input parameter.
