int irq_set_affinity(unsigned int irq, const struct cpumask *mask); ``` 参数解释: - `irq`:要设置亲和性的中断号。 - `mask`:要绑定中断的CPU核心的位图。 要使用 `irq_set_affinity` 函数,首先需要创建一个 `cpumask` 结构,用于表示要绑定的 CPU 核心。然后调用 `irq_set_affinity` 函数,将中断...
IRQ(中断请求)是硬件设备发送给CPU的一种信号,用于通知CPU某种事件(如数据接收、数据传输等)。在Linux中,IRQ设置可以通过irq_set_affinity函数来实现。 irq_set_affinity函数可以用来设置IRQ处理程序所在的CPU核心,能够实现对中断的控制。可以指定一个或多个CPU核心,这样IRQ处理程序就只会在这些CPU核心上执行。这对于...

i want to set all ethernet irq to bind with cpu0. but no lucky for me to set it. i am not sure what kind of problems i met. and i noticed affinity_hint has following value, and i cannot set it anyway. $sudo cat /proc/irq/109/affinity_hint ...
