Five years after running the vxworks driver, I was eager to switch to Linux kernel development. I would like to hear your comments and recommendation companies! -- Linux general technology-Linux programming and kernel information.

we went to install Hello.ko, there was this error: undefined symbol:This is because of the extern int function () in our program, which is not present in the system. Does that have to Insmod Function.ko first!?Although the system has already appeared function functions, but the system still cannot find. You can see that the error is still there.This is the problem with module export: When we are going to use a variable inside a module, the function must be exported using a symbol. That is, the

program is loaded by the BIOS or DOS, we do not know the segment address, so we do not know the program runtime in memory location.Now, loader is loaded by ourselves, the segment address has been identified as Baseofloader, so the physical address of the label (variable) appearing in loader can be represented by the following formula:The physical address of the designator (variable) =baseofloader*10h+ The offset of the label (variable)We put it and the corresponding statement in the Load.inc.Ba

Linux Kernel series-12. B. Operating System Development-jump from Loader to protection mode, 12. bloader Now, the kernel has been loaded into the memory. It is time to jump into the protection mode.
