Support for AMD CPUs - Githubissues

PhilippWendler commented 1 year ago

Recent AMD CPUs provide energy measurements via an interface that is similar to Intel RAPL. CPU Energy Meter should be made to work on these CPUs as well.

Blog post with information and measurements: https://metebalci.com/blog/epyc-energy-consumption-test/
Kernel driver amd_energy: https://github.com/amd/amd_energy (removed from mainline kernel)
The driver intel-rapl also supports AMD: https://github.com/torvalds/linux/blob/master/drivers/powercap/intel_rapl_msr.c
List with AMD's reference documentation: https://bugzilla.kernel.org/show_bug.cgi?id=206537
Another tool that supports this: https://github.com/deater/uarch-configure/blob/master/rapl-read/rapl-read.c
Overview of CPU families that support it: https://web.eece.maine.edu/~vweaver/projects/rapl/rapl_support.html
Tool from AMD that can read the information: AMD µProf

@TBunk would be great if we can support AMD CPU, that would make this tool work most of the system, then this will be a good candidate to included in debian/ubuntu packages

Sure, would be great! Unfortunately we currently don't have anyone with spare time to work on this.
