See 40-surface-power.rules for more details on how to obtain info about sensors

and cooling devices.

|

## Bonus
|
||||
|
||||
40-surface-power.rules also contains power-related tweaks for:
|
||||
- `surface profile`: currently low-power vs. performance
|
||||
- Various PCIe powersaving strategies
|
||||
- Intel p-state control for turbo-boost
|
||||
|
||||
50-surface.conf contains sysctl tweaks advised by `powertop`.

## Installation

|
||||
- Make sure to install `surface-control`

|

- Install `thermal-cpu-cdev-order.xml` to `/etc/thermald/`
|
||||
- Install `thermald.service` to `/lib/systemd/system/` and overwrite the old one.
|

- Maybe install to `/usr/lib/systemd/system/` too.

## TODO
|

|

- I tried to update cpufreq governor and turbo in udev event triggers but it
|
||||
didn't work.
|
||||
- You can install `cpufreqctl` for that.
