android - 如何导出结构体成员

Question

我想知道如何访问我的 driver/driver.c 中的 name 成员 这是来自 include/linux/cpufreq.h 的代码

struct cpufreq_governor {
    char    name[CPUFREQ_NAME_LEN];
    int     (*governor) (struct cpufreq_policy *policy,
                 unsigned int event);
    ssize_t (*show_setspeed)    (struct cpufreq_policy *policy,
                     char *buf);
    int     (*store_setspeed)   (struct cpufreq_policy *policy,
                     unsigned int freq);
    unsigned int max_transition_latency; /* HW must be able to switch to
            next freq faster than this value in nano secs or we
            will fallback to performance governor */
    struct list_head    governor_list;
    struct module       *owner;
};

driver.c中有一个依赖于 Activity 调控器的函数。那么如何将其作为driver.c中的变量

Answer 1

CPUfreq 导出符号 cpufreq_get_policy您可以通过它获得保单。 cpufreq_policy已有成员(member)governor 。这就是您正在寻找的。
