Driver on Linux

[Christophe.LINDHEIMER at fr.thalesgroup.com]

Hi.

I am working on a PPC860.

I have developped two drivers.

The driver 2 needs to use functions that are in driver 1.
driver 1 is /dev/visu.

I thought I could make fd=open("/dev/visu", 0) in init of the driver 2 but I
get ooops.
I also need to make something like ioctl(fd, IO_Special... )but the function
ioctl is unknown in the kernel.

What is the right way to work when you need to do that ?

Thanks.

Chris
