Why is the Linux kernel considered to be SMP safe?
Code that is not SMP safe is said to be thread hostile or racey, in that the multiple threads can race into the code and cause bugs. The Linux kernel is SMP safe because it is highly threaded and capable of working on multiple processors.
Why does the Linux kernel support symmetric multi processing?
Because the Linux kernel supports symmetric multi-processing (SMP) it must use a set of synchronization mechanisms to achieve predictable results, free of race conditions.
What does SMP stand for in computer programming?
SMP is an acronym for Symmetric Multi Processing (meaning multiple CPUs of the same kind – pretty much.) “SMP safe” means that the code takes advantage of special instructions and features of the system to allow multiple different CPUs to update the same piece of memory with predictable, reasonable results.
What does it mean to compile a kernel?
Yes, compiling a kernel usually means: Downloading the source code. Possibly modifying the source code (most non-programmers don’t usually do this). Configuring the kernel (what features/modules/drivers to include, etc.) Compiling it.
