| For what it's worth, it's just a change in GENERIC. It's not hard to
| compile a kernel with different options,
That's what I've been doing for years, with e.g.
# options INET6 # IPv6 communications protocols
# device cbb # cardbus (yenta) bridge
# device pccard # PC Card (16-bit) bus
# device cardbus # CardBus (32-bit) bus
in my kernel configuration on 8; there was no snd_hda there, and this
is why I asked about the possibly new kernel modularization in 9.
| So recompile GENERIC without snd_hda, you're a power user.
Yes, I see it in 9 now:
uname -sr; grep -iE 'snd|hda' /usr/src/sys/amd64/conf/GENERIC
=>
FreeBSD 8.2-STABLE
uname -sr; grep -iE 'snd|hda' /usr/src/sys/amd64/conf/GENERIC
=>
FreeBSD 9.0-STABLE
device snd_es137x # Ensoniq AudioPCI ES137x
device snd_hda # Intel High Definition Audio
device snd_ich # Intel, NVidia and other ICH AC'97
Audio
device snd_uaudio # USB Audio
device snd_via8233 # VIA VT8233x Audio
The presence of /boot/kernel/snd_hda.ko in 9 did confuse me.
| The handbook is an excellent resource if you've never done it. It's
| actually nice to have a minimal kernel config available for any kind
| of testing. Or reboot a few times, it's not that bad!
That's another thing for me to decide on: as I said, I used to
eliminate building some parts of the kernel but have recently decided
that it might be easier to just use GENERIC -- the resources and sizes
are no longer worth worrying about.
I have a better understanding of the situation now and will do some
adjustments.
Thanks,
