Android sched_setscheduler的权限,android,linux,scheduling,Android,Linux,Scheduling,进程需要什么权限来更改其调度策略？我试图设置SCHED_FIFO策略（在Android上运行平台服务），但使用EPERM失败 struct sched_param param; memset(&param, 0, sizeof(param)); int max_prio_for_policy = sched_get_priority_max(SCHED_FIFO); param.sched_priority = max_prio_for_policy;

进程需要什么权限来更改其调度策略？我试图设置SCHED_FIFO策略（在Android上运行平台服务），但使用EPERM失败

    struct sched_param param;
    memset(&param, 0, sizeof(param));
    int max_prio_for_policy = sched_get_priority_max(SCHED_FIFO);
    param.sched_priority = max_prio_for_policy; 

    if(0 != sched_setscheduler(0, SCHED_FIFO, &param)) ...
一般来说，流程需要哪些权限来提升其优先级？是否只允许root用户使用？用户进程能否提高其优先级
