I'm also interested in using the performance monitor, but my only
concern is if user processes will able to access the performance
counters directly with a "mov 1,PMD[r2]" instruction, instead of
having to use some sort of kernel service to access the counter.
Essentially, all I'm looking for is a replacement for the IA-32's
"RDTSC" instruction in the code I'm porting.
