Hi, I just committed code to impliment simple locks for SMP. I created a simple lock (imen_lock) to lock the critical region of "IO APIC & apic_imen" accesses. I moved the code that accesses these critical regions *outside* of the GL (mp_lock). It seems to work!!! YMMV, be aware that I will be mucking with other sections of the ISRs next, so you may want to avoid updates for any "important" systems for awhile... (ie its time to break things). But otherwise, please test this code if you can. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
