Re: Syscall Creation Question - New Member

Hi, Thank you for your reply. Part of the assignment is to make a system call and then the second part is to make the module version so we can learn ways. I really don't know what I am doing to be honest. I haven't received very much direction so I have been trying to scour the interne

Re: Module stacking & warnings

How do you know MY_SYMBOL is exported correctly? Have you tried explicitly exporting (EXPORT_SYMBOL(MY_SYMBOL)) in your code to get rid of the warning during make? If you can get rid of the error during make, you will be able to insmod the module. Dinesh Benedict, Michael wrote: I am trying

Re: preempt_disable() - disables preemption on all processors?

Module stacking & warnings

I am trying to implement module stacking for my embedded target. Everything seems to work fine with no errors, but there are disconcerting warnings in modpost and insmod. 1) Building a module that accesses exported symbols - I get an warning for every symbol like: WARNING: "" [.ko] undefined! I s
