Are the README's kernel config option requirements current?
https://github.com/fenrus75/powertop
Of those listed, these four are missing from default Fedora kernels (I
checked config-4.9.0-1.fc26.x86_64)
CONFIG_USB_SUSPEND
CONFIG_PERF_COUNTERS
CONFIG_EVENT_POWER_TRACING_DEPRECATED
CONFIG_ACPI_PROCFS_POWER
I have no idea if those missing relate to the following issues:
[root(a)f25h ~]# ls -l /var/cache/powertop/
total 0
-rw-r--r--. 1 root root 0 Dec 29 14:49 saved_parameters.powertop
-rw-r--r--. 1 root root 0 Dec 29 14:49 saved_results.powertop
These files are also zero byte files. They remain zero bytes even after
'powertop -c' although their time stamp changes.
