How to program in kernel ?

["Eric Delcamp" <edelcamp%easynet.fr@localhost>]

Hi,

I try to implement a minimun set of IOCTL in kernel, for the amiga graphic
chipset (grf_cc.c).
Can I do ioctl() and malloc() / free() inside the kernel ?

Another problem is ioctl() call get an error at compile time (implicit
declaration of function ioctl()), but I already included <sys/ioctl.h>. How
to do such things ?

Thanks.
