tools/power/turbostat: Fix turbostat for AMD Zen CPUs
BugLink: https://bugs.launchpad.net/bugs/1928183
It was reported that on Zen+ system turbostat started exiting,
which was tracked down to the MSR_PKG_ENERGY_STAT read failing because
offset_to_idx wasn't returning a non-negative index.
This patch combined the modification from Bingsong Si and
Bas Nieuwenhuizen and addd the MSR to the index system as alternative for
MSR_PKG_ENERGY_STATUS.
Fixes: 9972d5d84d76 ("tools/power turbostat: Enable accumulate RAPL
display")

BTW it looks like you will need to install more than just linux-tools-common
deb. On a 21.04 clean install, if I just install linux-tools-common the
turbostat command will complain about:
$ turbostat
WARNING: turbostat not found for kernel 5.11.0-17
You may need to install the following packages for this specific kernel:
linux-tools-5.11.0-17-generic
linux-cloud-tools-5.11.0-17-generic
I will have to install 5.11.0-18 kernel/header/module/module-extras debs and
other two tools-5.11 deb files to make it work on 5.11.0-18
Can you give it a try?
Thanks
