Description of problem:
SELinux is preventing x86_energy_perf from read, write access on the chr_file msr.

*****  Plugin device (91.4 confidence) suggests   ****************************

If you want to allow x86_energy_perf to have read write access on the msr chr_file
Then you need to change the label on msr to a type of a similar device.
# semanage fcontext -a -t SIMILAR_TYPE 'msr'
# restorecon -v 'msr'

*****  Plugin catchall (9.59 confidence) suggests   **************************

If you believe that x86_energy_perf should be allowed read write access on the msr chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'x86_energy_perf' --raw | audit2allow -M my-x86energyperf
# semodule -X 300 -i my-x86energyperf.pp
