| |
I am trying to add a new system call to my kernel, which is 2.0.36. When trying to call this from userland, using a function created with _syscall1, I get the error that the function is not implemented errno 38.
I have added #define __NR_newop 190 to unistd.h
I have also added .long SYMBOL_NAME(sys_newop) /* 190 */ to entry.S
and changed the line after that to: .space (NR_syscalls-190)*4.
I put source code in kernel/newop.c and added newop.o to the O_OBJS in kernel/Makefile.
I have also rebuilt the kernel from scratch, make dep; make clean; make zImage, and booted off this image.
Is there anything else I need to do?
Thanks a lot! Tim
