摘要： 现在我们来看看driver是如何从WLAN chipset那里接收数据的在上一篇文章中提到，数据过来时会产生中断，而在brcms_attach()函数体中，注册的interrupt handler是brcms_isr()，所以数据过来触发的第一个函数就是brcms_isr()。1. 触发brcms_isr()static irqreturn_t brcms_isr(int irq, void *dev_id){ struct brcms_info *wl; irqreturn_t ret = IRQ_NONE; wl = (struct brcms_info *) dev_i... 阅读全文
