I tried the latest kernel patch perfmon-new-base-070725.tar.gz and it could work
for the privous simple examples.

But when I tried dear-hist, the output is just one line. I expect it would
output many lines and every line represents an instruction (or data) address 
with an
latency/event counter. Perhaps the parameters I inputted are incorrect?

I didn't find examples about DEAR/IEAR from the help documentation.

Thanks.
