[comp.unix.wizards] device driver question.

gtusar@dante.nmsu.edu (Gregory A. Tusar) (05/23/89)

I'm currently writing a driver for an array processor type board
that lives on the multibus of a sun 2..

The question I have has to do with some bizarre behavior upon
trying to install the code and compile the kernal. 
I have an include file that gets copied into /usr/sys/WHATEVER, 
and it looks something like (at least in my directory) :

/* ~/md.h */
	#define	 NDEVICES	1
	#define	 PROBESIZE	(16 * 1024)

but when it gets copied into /usr/sys/WHATEVER (by config), the
PROBESIZE define goes away.. What the hack is going on?
The code works fine and the kernal compiles ok, but this still bothers me..

thanks,
greg
