我是Linux新手,我想知道驱动程序的内部以及它如何与硬件进行交互,所以我的问题是,How the application is interacting with hardware
意味着当core part
会出现在图片中,它会做什么?应用程序如何在Linux中与硬件进行交互?
当该驱动程序的controller
将来,以及它将如何处理由应用程序生成的请求。
什么是Firmware
当它在Linux中的图片?
For eg: if i am using usb device like
$ cat /dev/usb0.1
then which is the core of usb(usb_storage.c) and
which is the controller(usb_hub.c)
and how they are related to each other.
预先感谢..
