函数名称：Find the sched_domain_topology_level where all CPU capacities are visible* for all CPUs.

函数原型：static struct sched_domain_topology_level *asym_cpu_capacity_level(const struct cpumask *cpu_map)

返回类型：struct sched_domain_topology_level

参数：

类型参数名称
const struct cpumask *cpu_map
1925  asym_level等于0
1926  bool asym = false
1927  struct sched_domain_topology_level * tl, * asym_tl = NULL
1931  cap等于arch_scale_cpu_capacity(Uniprocessor. Assume all masks are "1". )
1934  如果arch_scale_cpu_capacity(i)不等于cap则
1935  asym = true
1936  退出
1940  如果非asym则返回:NULL
1949  max_capacity等于arch_scale_cpu_capacity(i)
1950  tl_id等于0
1953  如果tl_id小于asym_level则转到:next_level
1959  capacity等于arch_scale_cpu_capacity(j)
1961  如果capacity小于等于max_capacity则继续下一循环
1964  max_capacity等于capacity
1965  asym_level等于tl_id
1966  asym_tl等于tl
1968  next_level :
1969  tl_id自加
1973  返回:asym_tl
