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.
|
||||
|
||||
# Enable & Disable CPU threads
|
||||
|
||||
Enable: `echo 1 > /sys/devices/system/cpu/cpu{cpu_number}/online` where `{cpu_number}` is a number from 1 to 7 (inclusive).
|
||||
|
||||
Disable: `echo 0 > /sys/devices/system/cpu/cpu{cpu_number}/online` where `{cpu_number}` is a number from 1 to 7 (inclusive).
|
||||
|
||||
NOTE: You cannot enable or disable cpu0, hence why there are only 7 in the range for 8 cpu threads.
|
||||
|
||||
# Enable & Disable CPU boost
|
||||
|
||||
Enable: `echo 1 > /sys/devices/system/cpu/cpufreq/boost` enables boost across all threads.
|
||||
|
||||
Disable: `echo 0 > /sys/devices/system/cpu/cpufreq/boost` disables boost across all threads.
|
||||
|
||||
# Set CPU frequency
|
||||
|
||||
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
|
||||
|
||||
NOTE: PowerTools no longer supports this, since [Fantastic](https://github.com/NGnius/Fantastic) does it much better.
|
||||
|
||||
Enable automatic control: `echo 0 > /sys/class/hwmon/hwmon5/recalculate` enables automatic fan control.
|
||||
|
||||
Disable automatic control: `echo 1 > /sys/class/hwmon/hwmon5/recalculate` disables automatic (temperature-based) fan control and starts using the set fan target instead.
|
||||
|
||||
Set the fan speed: `echo {rpm} > /sys/class/hwmon/hwmon5/fan1_target` where `{rpm}` is the RPM.
|
||||
|
||||
Read the actual fan RPM: `cat /sys/class/hwmon/hwmon5/fan1_input` gives the fan speed.
|
||||
|
||||
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.
|
||||
|
||||
NOTE: 7.7 is the voltage of the battery -- it's not just a magic number.
|
||||
|
||||
# Steam Deck kernel patches
|
||||
|
||||
This is how I figured out how the fan stuff works.
|
||||
I've only scratched the surface of what this code allows, I'm sure it has more useful information.

# Game launch detection
|
||||
|
||||
```typescript
|
||||
//@ts-ignore
|
||||
let lifetimeHook = SteamClient.GameSessions.RegisterForAppLifetimeNotifications((update) => {
|
||||
if (update.bRunning) {
|
||||
console.log("AppID " + update.unAppID.toString() + " is now running");
|
||||
} else {
|
||||
console.log("AppID " + update.unAppID.toString() + " is no longer running");
|
||||
// game exit code here
|
||||
// NOTE: custom games always have 0 as AppID, so AppID is bad to use as ID
|
||||
}
|
||||
});
|
||||
//@ts-ignore
|
||||
let startHook = SteamClient.Apps.RegisterForGameActionStart((actionType, id) => {
|
||||
//@ts-ignore
|
||||
let gameInfo: any = appStore.GetAppOverviewByGameID(id);
|
||||
// game start code here
|
||||
// NOTE: GameID (variable: id) is always unique, even for custom games, so it's better to use than AppID
|
||||
});
|
||||
```
