Hi Chanwoo,

I think it doesn't help on the benchmark I suggested that is doing only memory
accesses. With both timer, I have the same timing.

To test the benchmark with these new patches about timer:

git clone https://github.com/wwilly/benchmark.git \
&& cd benchmark \
&& source env.sh \
&& ./bench_build.sh \
&& bash source/scripts/test_dvfs_mem_patched.sh

The benchmark is set by default to run for 1s, but you can increase this by
tweaking the script as:

taskset 8 ./bench_install/bin/microbe_cache 33554431 0 9722222 <TIME in sec> ${little_freq}

Also, as I reported the issue, would it be possible to add a

Many thanks in advance.
