Hello, I am trying to use amdctl to undervolt my laptop with a turion p450. I compiled the code, but when trying to change any settings I am given an error that refrences how it is unable to access /dev/cpu/1/msr. I ran sudo modprobe msr with no errors, but the module is still not readable or modifiable. Any advice how this device file can be read or modified?
I also tried rdmsr, which says operation not permitted. sudo modprobe msr does not create /proc/msr though.
