[PATCH 0/2] Add missing run-time dependency for TLP (Power management tool for Linux). |
Date: |
Sat, 20 Apr 2019 16:26:31 +0000 |
Hello.
The first patch will add system (arch-kernel) specific
x86-energy-perf-policy package,
and the second patch will adjust TLP package to use
x86-energy-perf-policy as a optional/system-specific run-time
dependency.
To understand my motivation please take a look at:
- https://linrunner.de/en/tlp/docs/tlp-configuration.html#scaling
the section explaining ENERGY_PERF_POLICY_ON_AC parameter has the
following note:
"Important: this setting requires the kernel module msr and the tool
x86_energy_perf_policy matching your kernel version."

I reworded it to use ‘filter-map’ intead of (filter string? …).

This would not work, because ‘%current-target-system’ returns a
“triplet”, not a “system type”, so I’ve also rephrased it.
Let me know if something’s broken!
Thanks,
