Subject: sim: Expose the current clock period as a stat
X-Git-Tag: stable_2014_08_26~210
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1d85e914a6b7a9b3550e84d2006ba775a27a0a44;p=gem5.git

sim: Expose the current clock period as a stat

This patch adds observability to the clock period of the clock domains
by including it as a stat.

As a result of adding this, the regressions will be updated in a
separate patch.
