Multicore processor os dev

[linuxfreak]

Hi all,

I read somewere that when developing an os you need to manualy enable the rest of the processor cores(if it has more than one). If this is true how would i go about doing this or has mike already written something about this in his os dev tutorials. What interrupt is needed and maby a example of code would realy help.

I appreciate any future help

Hello,

The x86 family of processors follow Intel's MP Specification which outlines the details for initializing the other processors. I personally advise reading the specification as it provides OS design related information that is recommended for proper MP support.

I am unaware of any tutorial that covers this specific topic as it is advanced and typically OS design centric.
