For the author's S3C2410 Development Board, Ram is connected to the physical address 0x30000000, and 0x30000000 ~ when the call _ create_page_tables ends ~ 0x30400000 physical address will be mapped to 0xc0000000 ~ 0xc0400000 virtual address.

For each configuration option, the user can answer "y", "M", or "n". where "Y" means the support or device driver of the corresponding feature is compiled into the kernel; "M" means that the support or device driver for the corresponding feature is compiled into a loadable module, which can be added to the ke

What the modules can do is limited-for example, they can't add or subtract fields from public data structures such as process descriptors (LCTT: It can disrupt the entire kernel and the system's functionality). However, in other ways, they are mature kernel-level code that can be compiled into the kernel at any time when needed (so that all restrictions can be
