Hi,

Can anyone explain what the function thread_funnel_set() does? Is it some means of synchronization/locking mechanism to critical kernel data structures??

Regards, Bijoy Thomas.

Fore pre-Tiger, yes, thread funnels were basically giant locks. There was one for networking and one for everything else in the BSD kernel. I'm surprised that they are still in Tiger, as that is supposed to be one of the big changes in the Tiger kernel: no more funnels. I can only surmise that they are there for some kind of backward compatibility, but since all NKE and FS kext's have to be updated to the kpi's I don't know who that compatibility would be for.
