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. -- Gene McCulley mcculley@iag.net http://www.iag.net/~mcculley
