Hi,
You might want to take a look at Documentation/cpu-hotplug.txt for some details regarding online/possible CPUs...
ah, quite so, although that file is definitely out of date. it doesn't mention the command-line parameters "nosmp" or "nr_cpus=" which are defined in kernel/smp.c. more in a bit ...
I believe you'll find them in Documentation/kernel-parameters.txt. Of course, it would be good to have them documented or at least mentioned in the above file (cpu-hotplug.txt) as well..
while it's useful, the kernel-parameters.txt file is notoriously behind the times. in this case, it does mention "nosmp" and "nr_cpus" but doesn't mention the X86-only "possible_cpus" parameter. oh, well ... rday -- ======================================================================== Robert P.
