I have a DIY 11th gen Framework Laptop (CPU: i5-1135G7) running Ubuntu 22.04. I’m trying to read the RAPL MSR’s for my work regarding energy estimates of software products.
I can read the energy_pkg domain just fine, however the DRAM domain always returns a value of 0. I am unsure if this is because the functionality is simply not available for my specific processor, or I need to turn on some setting somewhere. I haven’t been able to find any documentation that says whether this is possible on my cpu.
I found this info here(https://github.com/intel/powergov) that seems to imply a BIOS setting may be needed to be turned on, but my BIOS does not have the mentioned memory options. In fact my bios settings are quite barebones.
FWIW, the code I’m running does provide dram energy readings on other machines - I’m just having an issue on my framework laptop.
So in short - does anyone have any experience with this?
