函数名称:Allocate vector number for each node, so that for each node:* 1) the allocated number is >= 1* 2) the allocated numbver is <= active CPU number of this node* The actual allocated total vectors may be less than @numvecs when
函数原型:static void alloc_nodes_vectors(unsigned int numvecs, cpumask_var_t *node_to_cpumask, const struct cpumask *cpu_mask, const nodemask_t nodemsk, struct cpumask *nmsk, struct node_vectors *node_vectors)
返回类型:void
参数:
| 类型 | 参数 | 名称 |
|---|---|---|
| unsigned int | numvecs | |
| cpumask_var_t * | node_to_cpumask | |
| const struct cpumask * | cpu_mask | |
| const nodemask_t | nodemsk | |
| struct cpumask * | nmsk | |
| struct node_vectors * | node_vectors |
| 135 | remaining_ncpus等于0 |
| 137 | 以n小于nr_node_ids循环 |
| 146 | ncpus等于pumask_weight - Count of bits in *srcp*@srcp: the cpumask to count bits (< nr_cpu_ids) in. |
| 148 | 如果非ncpus则继续下一循环 |
| 150 | remaining_ncpus加等于ncpus |
| 154 | numvecs等于min_t - return minimum of two values, using the specified type*@type: data type to use*@x: first value*@y: second value(unsigned, remaining_ncpus, numvecs) |
| 156 | sort(node_vectors, nr_node_ids, node_vectors[0]的长度, ncpus_cmp_func, NULL) |
| 227 | 以n小于nr_node_ids循环 |
| 233 | WARN_ON_ONCE(numvecs == 0) |
| 236 | nvectors等于max_t - return maximum of two values, using the specified type*@type: data type to use*@x: first value*@y: second value(unsigned, 1, numvecs * ncpus / remaining_ncpus) |
| 238 | WARN_ON_ONCE(nvectors > ncpus) |
| 242 | remaining_ncpus减等于ncpus |
