MSR

Is it possible for me to use the cycle counter MSR entirely from user
space? I hack a simulation application that uses the cycle counter on
the SGI. The advantage to using the cycle counter is that it serves
as a super fast, super accurate gettimeofday. This is important to my
simulation. It would be nice if I could get the same kind of
advantage on Linux/i386.
FYI: Already, this application benchmarks better on a Pentium Pro 200
than on a 195MHz r10000 SGI Indigo2. And the SGI has the unfair
advantage of not having to byte swap a lot of network traffic and
having a cycle counter.
