I will discuss the current status of kernel SMP support, the rthreads thread library, and relevant future developments. Over the years, we have accumulated several concurrency primitives in the kernel, causing some confusion amongst developers, so I will lay out the origin and correct usage for each. The talk is primarily targeted at the budding OpenBSD kernel developer, but I will also describe the end-user effects of each topic.
