Hello friends,

I wonder if anyone can help me out on this.
I was learning to write a basic dummy device driver from "Device Driver
Tutorial" (http://docs.sun.com/app/docs/doc/817-5789/)

The code I inherited from the book compiled successfully on my computer. I
use Opensolaris 2009.06, sunstudio compiler, amd64.
I have placed the dummy.conf in /usr/kernel/drv/amd64 and created the
soft-link to /tmp/dummy in /usr/kernel/drv/amd64.

When I tried to add the driver using

#add_drv dummy

I got the error:

devfsadm: driver failed to attach: dummy
Warning: Driver (dummy) successfully added to system but failed to attach

Even I am not able to get the notices about _info and _init in
/var/adm/messages.

The book gives 2 reasons for this:

   - Device may not be detected correctly.
   - The <driver_name>.conf file is missing or wrongly placed.

when I do
#prtconf -D
I am able to see that dummy device is there but (driver not attached) is
written.

Can anyone help me out???
