函数名称:__cpuhp_setup_state_cpuslocked - Setup the callbacks for an hotplug machine state*@state: The state to setup*@invoke: If true, the startup function is invoked for cpus where* cpu state >= @state*@startup: startup callback function*@teardown: teardown
函数原型:int __cpuhp_setup_state_cpuslocked(enum cpuhp_state state, const char *name, bool invoke, int (*startup)(unsigned int cpu), int (*teardown)(unsigned int cpu), bool multi_instance)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
enum cpuhp_state | state | |
const char * | name | |
bool | invoke | |
int (* | startup | |
int (* | teardown | |
bool | multi_instance |
1754 | ret等于0 |
1757 | lockdep_assert_cpus_held() |
1759 | 如果Sanity check for callbacks 或非name则返回:负EINVAL |
1762 | mutex_lock( & cpuhp_state_mutex) |
1764 | ret等于cpuhp_store_callbacks(state, name, startup, teardown, multi_instance) |
1767 | dynstate等于state恒等于CPUHP_AP_ONLINE_DYN |
1781 | st等于per_cpu_ptr( & cpuhp_state, cpu) |
1788 | 如果ret则 |
