I didn't change any parameters, I just used the SMP kernel configuration
from the source tree (i.e., GENERIC plus "options SMP").

Thanks for the kernel.
What parameters did you change in your SMP kernel.
Just curious, surely gonna try your kernel. :-)
Thanks,

Mipam.

Ok, I've gone through my log files, and it looks like the number of systems
downloading SMP kernels is around 4% - 6% of the number of systems downloading
GENERIC kernels.

That said, I don't think this should be used as a measure of how popular SMP
is on FreeBSD systems overall, since people with high-end SMP systems are more
likely than average to build their own kernels rather than using those which
I distribute and the availability of SMP kernels via FreeBSD Update wasn't
very widely advertised.  It is probably safe to conclude that _at least_ 5%
of FreeBSD systems have more than one processor, but I suspect that the actual
value is considerably higher than that.

I'm curious how popular.  Would you like to report some statistics here 
on the list?  As in, how many SMP downloads did you get, say, in 
comparison to the GENERIC?  I wonder just how popular SMP has become.  I 
ran dual Pentium 120s on a 430HX motherboard once a long time ago.  And 
I know SMP goes farther back to at least the Pentium 60.  Back then, it 
was pretty unusual, but I wonder what it's like now.


Thanks.

BTW, nice idea you've got.  I tried to use it back before you offered 
SMP kernels and was disappointed.

FreeBSD 5.4 SMP kernels now available via FreeBSD Update

2005-06-15 Thread Colin Percival
It sounds like the SMP kernel I provided for FreeBSD 5.3 was quite
popular, so I've started building an SMP kernel for FreeBSD 5.4 as
well, in addition to the usual GENERIC kernel.  To take advantage
of this on your FreeBSD 5.4 SMP system, run the following commands
as root:

# touch /boot/kernel/SMP
# freebsd-update fetch
# freebsd-update install
# echo 'bootfile="SMP"' >> /boot/loader.conf

and reboot.  You should now find that `uname -ri` outputs "5.4-SECURITY SMP".
