Shirley> I read the documentation again, I think I was wrong. It Shirley> returns 64 bit always. I don't think that's correct. How could mftb return a 64-bit value on a CPU with 32-bit registers? The best thing to look at is the definition of get_tb() in in the kernel tree. I think that should give something that always works. - R. ___ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general

I read the documentation again, I think I was wrong. It returns 64 bit always.

What svn revision is it fixed in? 5159 is running the tests now, but I can cancel and resubmit if it was fixed after that.
