First distro with a smp kernel?
First distro with a smp kernel?
Hi all
Just a quick question to see what was the first puppy with a smp kernel, the earliest I have found is 431 does anyone know of anything earlier ?
Cheers

Hi all, hi stripe,
in my tests with puppy4.12 (Kernel 2.6.25.16)
I also had to check the kernel-sources.
There I had found some hints for you.
The kernel 2.6.25.16 for default boots in
single-cpu-mode.
But with the boot-parameter
maxcpus= [SMP]
( [SMP] is the maximum number of processors
that an SMP kernel should make use of)
the kernel tries to use more cpu-cores.
For example, with the boot-parameter (grub? in menu.lst?)
puppy ..... maxcpus=2
you can try it on a dual-core-cpu.
In the sources-doku of my old kernel 2.6.25.16 is also a hint,
that because on some platforms, the use of more than
one cpu could result in a hanging system, the default
is to boot in single-mode.
Search the internet for 'maxcpus' and 'nosmp' for more help.
But give it a try (I had never tested it )
hope it helps

If it has more than one processor, Htop will show more than 1 cpu inFlash wrote:I hadn't even tried Htop yet! Thanks for pointing it out. It's impressive, but at first glance I don't see where it's telling me how many chips or cores or whatever are being used.Stripe wrote:As far as I know, I just use Htop and hardinfo (to see the number of chips and if they are being used)
first line. (exceptions):
http://murga-linux.com/puppy/viewtopic.php?t=57241
Inspiron 700m, Pent.M 1.6Ghz, 1Gb ram.
Msi Wind U100, N270 1.6>2.0Ghz, 1.5Gb ram.
Eeepc 8g 701, 900Mhz, 1Gb ram.
Full installs
Here's what Menu -> System -> Htop shows for my computer. I presume the lines numbered 1 and 2 in the upper left refer to the cores in the CPU.
After reading this post I tried to find syslinux.cfg but it's not anywhere in my computer. Is that because I'm running Puppy from a multisession DVD?
