Hi George, I think you're looking for CONFIG_SMP and CONFIG_NR_CPUS. There are some details here: http://cateee.net/lkddb/web-lkddb/NR_CPUS.html.
One thing to note is that sometimes the Linux kconfigs set range restrictions on the number of CPU cores. Sometimes these limitations are based on hardware restrictions, such as the design of interrupt devices, and other times they are soft limits that can be fudged for running in gem5 (I don't recall the details off-hand, but it involves modifying a range parameter in kconfigs - check out: https://www.kernel.org/doc/Documentation/kbuild/kconfig-language.txt). Hope this helps, Joel On Thu, Aug 1, 2013 at 6:51 PM, George Michelogiannakis < [email protected]> wrote: > Hi all, > A quick question: I looked through the pre-compiled SMP kernel's config > file on the wiki, but I couldn't find the option for the maximum number of > CPUs it supports.
