set_cpus_allowed_ptr() will fail with -EINVAL if the requested affinity mask is not a subset of the task_cpu_possible_mask() for the task being updated. Consequently, on a heterogeneous system with cpusets spanning the different CPU types, updates to the cgroup hierarchy can silently fail...
Ultimately, the function set_cpus_allowed_ptr achieves the same outcome as sched_setaffinity, but employs task_struct instead of PID. Test case: # cd /sys/kernel/tracing # echo 0 > tracing_on # echo round-robin > hwlat_detector/mode # echo hwlat > current_tracer # unshare --fork --...

Android SWT 即 Android Software Watchdog Timeout。 System Server进程是Android的一个核心进程,里面为APP运行提供了核心的服务。如果System Server的一些核心服务和重要线程卡住,就会导致相应的功能异常。 如手机发生hang机,输入无响应,无法启动APP等一些不正常的情况。而且,如果没有一种机制,让这些服务复位的话,那么...
