Hello,

I am trying to make the jump from 12.4 to 14, and am wondering about
some changes to GENERIC.

For some reason, iwm has been renamed to iwn, fine. But in 12.4 I've also had a required firmare:

device=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 iwm3168fw

That seems to be lacking in GENERIC 14.

In addition, 12.4 had an usb audio device:
device=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 snd_uaudio

That I am heavily reliant on. That seems to be missing in 14 as well.

Neither is mentioned in UPDATING. Any information or further reading on this? Since it is a headless box, I'd like it to come up again with (wireless) network.


Finally, two more general questions:

options=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0NUMA

is generally not needed? I am not up to date wether newer cpus make
somewhat use of that internally.

Further, if going root on zfs, is ffs for some reasons still requred?

As for some other, more obsuce partitions, like for boot/efi (even
though those are msdos, but you never know the crosslinks) or for
bootloader related stuff?

Thanks

Ede


Hey Ede,

Just commenting on the NUMA option as I've no idea about the res= t of it.
In my industry, high frequency trading, NUMA is abso= lutely required for the best performance as latency is the `top dog` here.<= br>

<= /div>
To further this answer, all modern "enterprise grade" c= pu's have support NUMA.=C2=A0 "Home" or "Personal" = systems generally don't; at least not the several that I own.

Hope this helps!
