Heard quite a bit about this series of books from Yash (if I remember correctly). Am keen to get my hands on them too.

Comment on Spin locks and the vicious multi-threading cycle by Abhijeet

Abhijeet — Sun, 11 Sep 2011 08:31:33 +0000

Other than expected busy wait time, there are other reasons that will dictate which primitive to use. For instance, there are certain contexts in which you cannot go to sleep (interrupts), so spin lock is the only option there. Another twist to the story is that a lower priority thread/interrupt can grab a spin lock and be swapped out because a higher priority interrupt fires : the classic priority inversion problem. So there is a variant of spin lock that also disables interrupts in the local CPU. Here are some simple rules:

If u are in a thread or process context, and critical section is more than sleep time, use mutex and/or semaphores. If you are in contexts that do not allow sleeping like hard and soft interrupts, then use spin lock. If there is chance of priority inversion because say you are synchronizing between a kernel thread and interrupt, use spin lock with interrupt disable.
