Hello godfafa . How did you disable the MSR lock? I am trying my best to edit the RAPL power limits using the MSR reg 0x610 (MSR_PKG_POWER_LIMIT). I am using a Haswell processor. I have tried using the wrmsr command with root privileges. I also tried using the intel power_governor tool but that too did not work.I have also tried using the /sys/class/powercap/intel-rapl files to change the power limits but it throws error when i commit the changes. Lastly, I tried to change the lock bit (Bit 63) using the intel_rapl module. I used the rapl_write_raw_data function to try and edit the lock bit but that too didn't work. It does not throw any error so I am quite stuck. I wish to regulate the powerlimits freely in user mode. Please guide me. Thanks!
