Hello all, I am working on a project where I have to use DVFS to change the frequency of cores based on my evaluation of some counters that I inserted in the gem5 o3 cpu src code.
I followed the guidelines given on http://www.m5sim.org/Running_gem5#Experimenting_with_DVFS . But with these steps, the kernel will be the one who decides the performance levels of the cores at different point of time. But in my case I want to decide the levels based on some counters as mentioned above. Has anybody tried anything similar to that? I want to know how can I access and update the dvfs handler registers from within the cpu src code. Any help will be appreciated. Thanks, -- Warm regards Nimish Girdhar Department of Electrical and Computer Engineering Texas A&M University
