Hi Everybody,
I am a jackaroo to FreeBSD kernel. I have a question about how the kern=
el add all devices. =20
For example, in NetBSD, I can find the code in /sys/kern/init_main.c:
/* Attach pseudo-devices. */
for (pdev =3D pdevinit; pdev->pdev_attach !=3D NULL; pdev++)
(*pdev->pdev_attach)(pdev->pdev_count);
I know the NetBSD kernel add devices(such as storage device and network d=
evice) by them.
But in FreeBSD, I can not locate the place.
which part code should I read?
Thank you.

Best Regards
