/*
|
|
* Nodemasks provide a bitmap suitable for representing the
|
|
* set of Node's in a system, one bit position per Node number.
|
|
*
|
|
* See detailed comments in the file linux/bitmap.h describing the
|
|
* data type on which these nodemasks are based.
|
|
*
|
|
* For details of nodemask_scnprintf() and nodemask_parse_user(),
|
|
* see bitmap_scnprintf() and bitmap_parse_user() in lib/bitmap.c.
|
|
* For details of nodelist_scnprintf() and nodelist_parse(), see
|
|
* bitmap_scnlistprintf() and bitmap_parselist(), also in bitmap.c.
|
|
* For details of node_remap(), see bitmap_bitremap in lib/bitmap.c.
|
|
* For details of nodes_remap(), see bitmap_remap in lib/bitmap.c.
|
|
* For details of nodes_onto(), see bitmap_onto in lib/bitmap.c.
|
|
* For details of nodes_fold(), see bitmap_fold in lib/bitmap.c.
|
|
*
|
|
* The available nodemask operations are:
|
|
*
|
|
* void node_set(node, mask) turn on bit 'node' in mask
|
|
* void node_clear(node, mask) turn off bit 'node' in mask
|
|
* void nodes_setall(mask) set all bits
|
|
* void nodes_clear(mask) clear all bits
|
|
* int node_isset(node, mask) true iff bit 'node' set in mask
|
|
* int node_test_and_set(node, mask) test and set bit 'node' in mask
|
|
*
|
|
* void nodes_and(dst, src1, src2) dst = src1 & src2 [intersection]
|
|
* void nodes_or(dst, src1, src2) dst = src1 | src2 [union]
|
|
* void nodes_xor(dst, src1, src2) dst = src1 ^ src2
|
|
* void nodes_andnot(dst, src1, src2) dst = src1 & ~src2
|
|
* void nodes_complement(dst, src) dst = ~src
|
|
*
|
|
* int nodes_equal(mask1, mask2) Does mask1 == mask2?
|
|
* int nodes_intersects(mask1, mask2) Do mask1 and mask2 intersect?
|
|
* int nodes_subset(mask1, mask2) Is mask1 a subset of mask2?
|
|
* int nodes_empty(mask) Is mask empty (no bits sets)?
|
|
* int nodes_full(mask) Is mask full (all bits sets)?
|
|
* int nodes_weight(mask) Hamming weight - number of set bits
|
|
*
|
|
* void nodes_shift_right(dst, src, n) Shift right
|
|
* void nodes_shift_left(dst, src, n) Shift left
|
|
*
|
|
* int first_node(mask) Number lowest set bit, or MAX_NUMNODES
|
|
* int next_node(node, mask) Next node past 'node', or MAX_NUMNODES
|
|
* int first_unset_node(mask) First node not set in mask, or
|
|
* MAX_NUMNODES.
|
|
*
|
|
* nodemask_t nodemask_of_node(node) Return nodemask with bit 'node' set
|
|
* NODE_MASK_ALL Initializer - all bits set
|
|
* NODE_MASK_NONE Initializer - no bits set
|
|
* unsigned long *nodes_addr(mask) Array of unsigned long's in mask
|
|
*
|
|
* int nodemask_scnprintf(buf, len, mask) Format nodemask for printing
|
|
* int nodemask_parse_user(ubuf, ulen, mask) Parse ascii string as nodemask
|
|
* int nodelist_scnprintf(buf, len, mask) Format nodemask as list for printing
|
|
* int nodelist_parse(buf, map) Parse ascii string as nodelist
|
|
* int node_remap(oldbit, old, new) newbit = map(old, new)(oldbit)
|
|
* void nodes_remap(dst, src, old, new) *dst = map(old, new)(src)
|
|
* void nodes_onto(dst, orig, relmap) *dst = orig relative to relmap
|
|
* void nodes_fold(dst, orig, sz) dst bits = orig bits mod sz
|
|
*
|
|
* for_each_node_mask(node, mask) for-loop node over mask
|
|
*
|
|
* int num_online_nodes() Number of online Nodes
|
|
* int num_possible_nodes() Number of all possible Nodes
|
|
*
|

|
|
*
|
|
* int node_online(node) Is some node online?
|
|
* int node_possible(node) Is some node possible?
|
|
*
|
|
* node_set_online(node) set bit 'node' in node_online_map
|
|
* node_set_offline(node) clear bit 'node' in node_online_map
|
|
*
|
|
* for_each_node(node) for-loop node over node_possible_map
|
|
* for_each_online_node(node) for-loop node over node_online_map
|
|
*
|
|
* Subtlety:
|
|
* 1) The 'type-checked' form of node_isset() causes gcc (3.3.2, anyway)
|
|
* to generate slightly worse code. So use a simple one-line #define
|
|
* for node_isset(), instead of wrapping an inline inside a macro, the
|
|
* way we do the other calls.
|
|
*
|
|
* NODEMASK_SCRATCH
|
|
* When doing above logical AND, OR, XOR, Remap operations the callers tend to
|
|
* need temporary nodemask_t's on the stack. But if NODES_SHIFT is large,
|
|
* nodemask_t's consume too much stack space. NODEMASK_SCRATCH is a helper
|
|
* for such situations. See below and CPUMASK_ALLOC also.
