12.3. 将 CPU 从 IRQ 平衡中排除

流程

1. 在首选的文本编辑器中打开 /etc/sysconfig/irqbalance，并查找标题为 IRQBALANCE_BANNED_CPUS 的文件部分。

   # IRQBALANCE_BANNED_CPUS
   # 64 bit bitmask which allows you to indicate which cpu's should
   # be skipped when reblancing irqs. Cpu numbers which have their
   # corresponding bits set to one in this mask will not have any
   # irq's assigned to them on rebalance
   #
   #IRQBALANCE_BANNED_CPUS=

2. 取消注释 IRQBALANCE_BANNED_CPUS 变量。
3. 输入适当的位掩码，以指定 IRQ 平衡机制要忽略的 CPU。
4. 保存并关闭该文件。
