这个IRQ number是一个虚拟的interrupt ID,和硬件无关,仅仅是被CPU用来标识一个外设中断。 HW interrupt ID:对于GIC中断控制器而言,它收集了多个外设的interrupt request line并向上传递,因此,GIC中断控制器需要对外设中断进行编码。GIC中断控制器用HW interrupt ID来标识外设的中断。如果只有一个GIC中断控制器,那IRQ ...

RK为了方便开发与产品定制,自己定义了一套固件的分区,这些分区信息存放在parameter.txt文件中,Firefly参考这个文件定义了自己的Ubuntu分区,文件为parameter-ubuntu.txt,存放于Linux_SDK的device/rockchip/rk356x目录下;另外在Ubuntu固件打包的时候也会用到一个package-file文件,文件名为rk356x-ubuntu-package-file,存放于...

中断处理是通过IRQ number(虚拟ID)和HW interrupt ID(硬件关联ID)来标识的。中断服务函数,如handler(int irq, void *dev_id),处理特定中断,其中irq表示中断号,dev_id传递设备数据。在编写中断驱动程序时,需要理解GPIO映射的中断号,通过gpio_to_irq函数获取,同时注意中断处理的触发方式和同步...
