STRUCT TASK_CPUTIME(9) Driver Basics STRUCT TASK_CPUTIME(9)

NAME

struct_task_cputime - collected CPU time counts

SYNOPSIS

struct task_cputime {


  cputime_t utime;


  cputime_t stime;


  unsigned long long sum_exec_runtime;
};

MEMBERS

utime

time spent in user mode, in cputime_t units

stime

time spent in kernel mode, in cputime_t units

sum_exec_runtime

total time spent on the CPU, in nanoseconds

DESCRIPTION

This structure groups together three kinds of CPU time that are tracked for threads and thread groups. Most things considering CPU time want to group these counts together and treat all three of them in parallel.
