大桥的通行能力,就是CPU的最大工作量;桥梁上的车辆,就是一个个等待CPU处理的进程(process)。 如果CPU每分钟最多处理100个进程,那么系统负荷0.2,意味着CPU在这1分钟里只处理20个进程;系统负荷1.0,意味着CPU在这1分钟里正好处理100个进程;系统负荷1.7,意味着除了CPU正在处理的100个进程以外,还有70个进程正排队等着...
如果是 kprobe 机制触发的断点,会保存这个程序的状态,比如寄存器、堆栈等信息,并通过 Linux 的「notifier_call_chain」机制,将 cpu 的使用权交给之前 kprobe 的 probe handler,同时会把内核所保存的寄存器、堆栈信息传递给 probe handler。
