Hi Rahul,

I do not believe McPAT supports DVFS properly, so in any case your mileage may 
vary.

My guess would be that target_core_clockrate is what the cores where designed 
to achieve as their max clock rate.

Subject: [gem5-users] [gem5 users] a query regarding <target_core_clockrate> 
tag in Mcpat xml for ARM FS simulation

Hi All,

I am performing ARM FS simulation and want to calculate energy consumption of 
the program which contains calls to DVFS. I have generated some statistics and 
with the help of config.ini and stats.txt, I am trying to populate Mcpat xml 
file to calculate energy.

There is a parameter called <param name="target_core_clockrate"> under the 
component "System". Also there is a per core parameter called <param 
name="clock_rate"> for each of the simulated core. For per core parameter 
"clock_rate", I would set this to that frequency which each of the core is 
currently running on.(The value will be different for different core).

Since each core is running at different frequency, I am not sure what value to 
put in "target_core_clockrate", as this tag belongs to "system component" which 
necessarily is a global setting.
Could you please help me here?


Regards
Rahul
