Can you be more specific about this? when you say "driver", do you mean a kernel driver or a userland program. I assume it's a userland pseudo-driver that links with pthreads to achieve its threads? Geez. why don't they use the per-thread-storage that the library provides? What makes them think that %gs is free? I think that linux will start using %gs for the TLS too as well soon. It's used for Thread-local-storage in the pthreads library too, so they trash each other's TLS. do they allocate LDT entries to back their own storage? > > That makes them pretty much useless in -current, especially since > libc_r is on the way out. > > One wonders why they use pthread_key_create() et al, and still > need TLS. > > > I suppose I should have mentioned this. > > Probably :-) > > -- > Dan Eischen > > _______________________________________________ > freebsd-threads@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-threads > To unsubscribe, send any mail to "freebsd-threads-unsubscribe@freebsd.org" >
