kernel-kernel call communication
hi all!
i have developed a mechanism in system.c to count how many times each kernel call is called. The results are held in an array in system.c . What i want to do is to create a new kernel call which will print this array. I need help in passing the array from system.c to the new kernel call.
how can this be done?

I suggest you indicate the operating system you intend a solution for.

thanks for the reply, the operating system is minix.

Is the array held within the kernel? Why not provide an API that returns a copy of the array to a user program which can then print it out? If so ioctl/read etc should provide examples of how to transfer data from the kernel to user memory space using a syscall.

the array is held in the kernel and a kernel call do_XXXXX prints it out. these are the specifications.

Hi All, Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff. Cheers, Brendan (4 Replies)
