When compiling the kernel, I found a file named vmlinux. LDS. s under the arch/ARM/kernel directory. At first glance, do you want to compile a file? It seems that it is not. So what does it do?

To allow Linux to run on a brand new arm SOC, there are a number of underlying support, such as timer beats, interrupt controllers, SMP booting, CPU HotPlug, and the underlying GPIO, clock, Pinctrl, and DMA hardware packages. Timer beats, interrupt controllers, SMP boot, and CPU hotplug are relatively not as cluttered as the early Gpio, clock, Pinctrl, and DM

The previous chapter describes how to compile the Linux kernel. After an image is obtained, it can be burned to the Development Board for running. However, this will also cause some problems: for example, if you want to add or modify some Linux kernel configurations and components, you must re-compile the
