Howdy,
It looks like most of the ISA drivers now days have a frag like:
SYSINIT(foo,SI_SUB_DRIVERS,SI_ORDER_MIDDLE+CDEV_MAJOR,foo_drvinit,NULL)
foo_drvinit(void *nothing){
static int foo_devsw_installed=0;
dev_t dev;
if (! foo_devsw_installed ) {
dev = makedev(CDEV_MAJOR, 0);
cdevsw_add(&dev, &foo_cdevsw, NULL);
foo_devsw_installed = 1;
}
}
Is there any reason that this can't be absorbed in the attach function,
somewhere around where the devfs stuff is done? What's the reason for
adding yet another entry point during re-boot. Isn't probe/attach enough?
eric.
