Hi,
The following patch add the support for AMD CPU for RAPL MSR. This was
one of the two current limitation of the introduction patch.
This has been tested on AMD Ryzen 5850U. I was able to mount the RAPL
driver in a VM with '-cpu host'. The counter value are increasing
properly.
I added a second patch to silence an error that is not really an error.
I change it to a tracepoint following Daniel advice. Thanks Daniel !
Thanks
Anthony
