Hello everyone,
I am trying to experiment with changing CPU frequency in gem5
dynamically. I am trying to do so in a naive way (I am fairly new to
gem5). I am running with atomic cpu model and in the "cpu->tick"
function, I want to change the cpu frequency after a certain number of
ticks.
I see, there is a function "SrcClockDomain::clockPeriod(Tick
clock_period)" which I think I need to use to update the clock period so
that the frequency change can be propagated to all the members(including
my atomic cpu simulation object) of the clock domain to which my cpu
belongs. However I am not able to figure out where (in which file) and
how should I call this function. Could someone help me understand what I
am missing here ?
Am I on the right track? What is the right way to change cpu frequency
dynamically? I would really appreciate any help from the community.
Details:
I am attaching config.ini file alongwith.
Command used: build/X86/gem5.opt configs/example/fs.py
--disk-image=/home/ljindal/Downloads/GEM5/x86-system/disks/linux-x86.img
--kernel=/home/ljindal/Downloads/LINUX_IMAGE/linux/linux-2.6.28.4_experiment/vmlinux
--cpu-clock=1GHz
Thanks and Regards
Lokesh Jindal.
