1.cmci_storm_detect()函数主要是对cmci storm的处理,代码如下 static bool cmci_storm_detect(void) { unsigned int cnt = __this_cpu_read(cmci_storm_cnt); unsigned long ts = __this_cpu_read(cmci_time_stamp); unsigned long now = jiffies; int r; if (__this_cpu_read(cmci_storm_state) ...

the CPU(s) will then receive a constant influx or storm of interrupts at a high enough rate that it will impact the CPU's ability to do useful work. When that happens, the kernel disables the CMCI
CMCISTORMcmcistorm subsided UVa11059Maximum Product题意给一串整数S,你需要找到其连续子序列中乘积最大的那个,输出其乘积。如果找到的答案不是正数,那么输出0,表示无解。另外注意:每组输入后面都有一行空格,每组输出后面也应该有一行空格。输入以EOF结束。然后,按照UVa中的数据范围,它不是很大,差不多就是: 1<=n...
日志中的体现 kernel: CMCI storm subsided: switching to interrupt mode kernel: CMCI storm detected: switching to poll mode 上面是在message中输出的错误信息。我们知道CMCI架构每遇到一个错误就会产生一个中断。如果这个错误产生频率太高,CMCI架构就会切换到轮询模式(隔几秒报告一次),以减小对cpu的影响。当报错...
