69.1.1 irq_of_parse_and_map函数 该函数的主要功能是解析设备节点的"interrupts"属性,并将对应的中断号映射到系统的中断号。"interrupts"属性通常以一种特定的格式表示,可以包含一个或多个中断号。通过提供索引号,可以获取对应的中断号。 函数原型: unsigned int irq_of_parse_and_map(struct device_node *dev...

Since the PCI specification requires interrupt lines to be shareable, even a processor with a limited number of IRQ lines, like the x86, can host many PCI interface boards (each with four interrupt pins). The I/O space in a PCI bus uses a 32-bit address bus (leading to 4 GB of I...
scsi模块建立联系,从而把QEMU中模拟的SCSI设备部分传递到了内核态,即内核态对该SCSI设备不是完全模拟的,仅仅负责对virtqueue进行处理,因此这个ioctl的消息主要负责3部分的内容传递:Guest内存映射;Guest Kick Event、vhost-kernel驱动用来接收Guest的消息,当接收到该消息后即可启动工作线程;IRQ Event用于通知Guest的I/O完成...
