## Cool, whatever
## Cool, but that's too much work
Yeah, that's fair.
Fair enough.
In case you still want some of the functionality, without the nice GUI, here's some equivalent commands.
These should all be run as superuser, i.e. run `sudo su` and then run these commands in that.
@ -32,6 +32,14 @@ Use `cpupower` (usage: `cpupower --help`).
This isn't strictly how PowerTools does it, but it's a multi-step process which can involve changing the CPU governor.
All that can be done automatically by `cpupower frequency-set --freq {frequency}` where `{frequency}` is `1.7G`, `2.4G` or `2.8G`.
### Set GPU Power
Set Slow Powerplay Table (PPT):`echo {microwatts} > /sys/class/hwmon/hwmon4/power1_cap` where `{microwatts}` is a wattage in millionths of a Watt. This doesn't seem to do a lot.
Set Fast Powerplay Table (PPT): `echo {microwatts} > /sys/class/hwmon/hwmon4/power2_cap` where `{microwatts}` is a wattage in millionths of a Watt.
Get the entry limits for those two commands with `cat /sys/class/hwmon/hwmon4/power{number}_cap_max` where `{number}` is `1` (slowPPT) or `2` (fastPPT).
### Set Fan speed
Enable automatic control: `echo 0 > /sys/class/hwmon/hwmon5/recalculate` enables automatic fan control.
@ -45,6 +53,16 @@ Read the actual fan RPM: `cat /sys/class/hwmon/hwmon5/fan1_input` gives the fan
NOTE: There's a bug in the fan controller; if you enable automatic fan control it will forget any previously-set target despite it appearing to be set correctly (i.e. `cat /sys/class/hwmon/hwmon5/fan1_target` will display the correct value).
When you disable automatic fan control, you will need to set the fan RPM again.
### Battery stats
Get the battery charge right now: `cat /sys/class/hwmon/hwmon2/device/charge_now` gives charge in uAh (uAh * 7.7/1000000 = charge in Wh).
Get the maximum battery capacity: `cat /sys/class/hwmon/hwmon2/device/charge_full` gives charge in uAh.
Get the design battery capacity: `cat /sys/class/hwmon/hwmon2/device/charge_full_design` gives charge in uAh.
Get whether the deck is plugged in: `cat /sys/class/hwmon/hwmon5/curr1_input` gives the charger current in mA.
### Steam Deck kernel patches
This is how I figured out how the fan stuff works.
