函数名称:pdate_prstate - update partititon_root_state* Call with cpuset_mutex held.
函数原型:static int update_prstate(struct cpuset *cs, int val)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct cpuset * | cs | the cpuset to update |
int | val | 0 - disabled, 1 - enabled |
1921 | parent等于parent_cs( the cpuset to update) |
1924 | 如果 0 - disabled, 1 - enabled不等于0且 0 - disabled, 1 - enabled不等于1则返回:负EINVAL |
1926 | 如果 0 - disabled, 1 - enabled恒等于 partition root state 则返回:0 |
1933 | 如果 0 - disabled, 1 - enabled且 partition root state 则返回:负EINVAL |
1940 | 如果非 partition root state 则 |
1949 | err等于pdate_flag - read a 0 or a 1 in a file and update associated flag* Call with cpuset_mutex held. |
1955 | 如果err则 |
1956 | pdate_flag - read a 0 or a 1 in a file and update associated flag* Call with cpuset_mutex held. |
1957 | 转到:out |
1959 | partition root state 等于PRS_ENABLED |
1960 | 否则 |
1965 | 如果 partition root state 恒等于PRS_ERROR则 |
1966 | partition root state 等于0 |
1967 | pdate_flag - read a 0 or a 1 in a file and update associated flag* Call with cpuset_mutex held. |
1968 | err等于0 |
1969 | 转到:out |
1977 | partition root state 等于0 |
1990 | 如果child_ecpus_count则pdate_sibling_cpumasks - Update siblings cpumasks*@parent: Parent cpuset*@cs: Current cpuset*@tmp: Temp variables |
1993 | rebuild_sched_domains_locked() |
1994 | out : |
1996 | 返回:err |
名称 | 描述 |
---|---|
sched_partition_write | |
cpuset_css_offline | If the cpuset being removed has its flag 'sched_load_balance'* enabled, then simulate turning sched_load_balance off, which* will call rebuild_sched_domains_locked(). That is not needed* in the default hierarchy where only changes in partition |
