Hi Andres,
I also couldn't help and hacked a bit on the rdtsc pieces. I did figure out
how to do the cycles->nanosecond conversion with integer shift and multiply in
the common case, which does show a noticable speedup. But that's for another
day.
I also have code for that here. I decided against integrating it because
we don't convert frequently enough to make it matter. Or am I missing
something?
I fought a bit with myself about whether to send those patches in this thread,
because it'll take over the CF entry. But decided that it's ok, given that
David's patches should be rebased over these anyway?
That's alright.
Though, I would hope we attempt to bring your patch set as well as the
RDTSC patch set in.
