Hi,
I'd like to propose this patch for 2.6.0 or 2.6.1 to quite down some
of the excessive boot messages printed for each CPU. The patch simply
introduces a boot time variable 'smpverbose' which users can set if
they experience problems and want to see the full set of messages.
Once you hit > 2 CPUs the amount of noise printed per CPU starts
becoming a pain, at 64 CPUs it's turning into a royal pain ....
Oh and I also killed a NULL initializer in kernel/cpu.c - bad Rusty ;-)
Thanks,
Jes

Hi,
Here is an improved version. Andi suggested that I move the
smp_verbose prototype to include/linux/smp.h and I also nailed another
NULL initializer in init/main.c
Oh and I fixed my b0rked spelling as well - time to look at the screen
when typing ;-)
Cheers,
Jes

Just kill the silly option, these messages are completly useless.
And IIRC we didn't have them in 2.4 either..

Agreed. We got v. chatty during 2.5. In 2.6.<smallnum> we should
drop a lot of boot crud.

Some of them I agree could just be killed while others still have some
use. Thats why I suggest leaving in the boot option.

You might want to be more creative.. With something like < for each
cpu going up and > for each cpu booted, you might be able to preserve
all the info yet make it _way_ shorter.

Sounds promising to me. I also dislike the verbosity, but getting rid
of the messages completely makes me nervous, too, because sometimes
things do fail and then it's invaluable to have some idea of how far
the boot got (even if the person booting the machines has no clue what
the funny symbols on his screen actually mean).
