With the proliferation of dual processor pentium boards, I was wondering if anyone is working on a Symmetric MP version of FreeBSD, with fin grain MP locks (spin locks, semphores, simple mutexes without spins, and extended semaphores and mutexes; i.e. with the ability to sleep if resource locked). I came accross some source code which appears to come from I believe was the university of Minnessota, but perhaps from Berkeley, I am not sure. It implements a simple mutex lock around syscall. Even though is is rather primitive, I wonder if there is any current work in progress in this area. If you wish I can email you the uuencoded SMP.tgz file. It is based on FreeBSD 1.5.1. Cheers, Joe
