I am using FreeBSD Version 5.1. I am having problem to use the softc structure variables to assign the pointer to make_dev and bus_alloc_resource functions.
When I declare dev_t sdev as global variable and assign to make_dev as follows: int unit = device_get_unit(device); sdev = make_dev(&sy_cdevsw, 0, UID_ROOT, GID_WHEEL, 0600, "sy3c%d", unit); I am able to create device node, load the kld and unload the kld. When I declare dev_t dev as part of sy_softc structure and assign the scp->dev pointer to make_dev function as shown above, the code compiles ok. When I load the kld with "kldload -v ./sy3c.ko" command, it flags error. The errors log file err_log is attached. I have also attached the driver code for reference. Would you please advise a.s.a.p to resolve this problem. Regards Gurdial Chandra
