Hi Kazi, Srikant (CC'd) previously added some support for things like this (https://gem5-review.googlesource.com/c/public/gem5/+/61589), but in the L1/L2 caches instead of the CUs specifically. From a cursory check I don't see this support directly integrated into the CUs, but since they are ClockedObject's (https://gem5.googlesource.com/public/gem5/+/refs/heads/develop/src/sim/clocked_object.hh#107, https://gem5.googlesource.com/public/gem5/+/refs/heads/develop/src/sim/ClockedObject.py#50) my guess is you could use the above patch as a model to add the support you want.
If you do add it, it would be great if you can add this back as a feature for the community! Thanks, Matt ________________________________ From: Mejbaul Islam, Kazi M. via gem5-users <gem5-users@gem5.org> Sent: Monday, April 3, 2023 3:49 AM To: gem5-users@gem5.org <gem5-users@gem5.org> Cc: Mejbaul Islam, Kazi M. <kmejbaulis...@ufl.edu> Subject: [gem5-users] How to change voltage and frequency of individual ComputeUnit for GPU? Hello, In gem5/configs/example/apu_se.py, ComputeUnit is used to build GPU. Is there any way to change voltage and frequency of each individual ComputeUnit? Best, Kazi
