I was working with SUN's driver developer kit (DDK), when i found that there
samples would not attach to the running kernel. What am I doing wrong?
1. Compiled using Sun's compiler. The makefile has the -D_KERNEL option,
and it is linked with the "-r" option, both required for device drivers.
2. Moved the resultant driver to /usr/kernel/drv. There was no hardware
configuration file.
3. Ran "add_drv driver_name". At this point it returns with:
drvconfig: System call 'modctl_modconfig' failed: No such device or address
Warning: Driver (modsp) configuration failed.
System could not install the driver.
What have I missed? I tried the above procedure with a small test driver
that i had written. It gave the same error message. It does appear to
call the _info, _init, and unfortunatly, _fini routines. A hardware
configuration file made no difference to the results.
Any pointers, hints, or good ideas are appreciated.
