refactor: Add global toggle for in-game power control, fix issues - #1845
Conversation
Introduces a master switch to enable or disable all in-game power control features. This allows users to prevent the app from taking over CPU/GPU clock management from the OS. - Adds a "Power Control" toggle to settings to set the default state. - The `PowerManager` now conditionally activates its features based on this toggle, and the UI reflects this state by hiding/disabling sub-controls when power control is off. - Refactors `PowerManager`'s lifecycle and `PServerDriver`'s initialization to streamline logic and simplify driver interactions. - Update `PID Controller` implementation logic to give different min / max values

In `@app/src/main/java/app/gamenative/powercontrol/drivers/PServerDriver.kt`:
- Around line 44-48: Change the cpuPolicies and cpuClusters properties in
PServerDriver from lateinit declarations to instance-scoped properties
initialized with emptyList() and emptyMap(). Ensure getCpuCoresByCluster(),
getCpuClusterCount(), and policyForCluster() safely observe these defaults
before asynchronous CPU discovery completes.
In `@app/src/main/java/app/gamenative/powercontrol/PowerManager.kt`:
- Around line 222-231: The setPowerControlEnabled toggle must not call the full
stop path when disabling power control, because stop clears session state needed
while the game remains running. Separate runtime controller shutdown from
session teardown, keeping containerDir, isGameStarted, ownsGameAffinity, and
pinned-game fields owned by autoStart/stop; use the lighter runtime-disable path
in setPowerControlEnabled(false), and ensure the toggle flow saves the profile
on both enable and disable as indicated by the “Always save the profile”
contract.
- Line 84: Initialize currentProfile in initialize(context) with the existing
default PowerProfile after the driver setup, ensuring all public methods can
safely read it before autoStart invokes loadCurrentProfile().
- Around line 1491-1501: Update loadCurrentProfile() to catch profile file read
and PowerProfile decode failures, including corrupt or incompatible persisted
data, and assign getDriverDefaultProfile() when either fails. Preserve the
existing file-missing fallback and successful restoration behavior so profile
errors cannot propagate into autoStart.
In `@app/src/main/java/app/gamenative/powercontrol/PowerProfile.kt`:
- Around line 3-5: Update the PowerProfile preview constructions to pass an
explicit enablePowerControl value, avoiding the PrefManager-backed default
during `@Preview` rendering while preserving production initialization behavior.

- Line 264: Cache the capability probe results with Compose remember in the

isFanControlAvailable, isGamePinningAvailable, and isClusterTuningAvailable so
each probe runs once per composition instead of on every recomposition.

- Around line 155-173: Update the onMinCpuValueChanged and onMaxCpuValueChanged

PowerManager setter rather than substituting 0L; preserve profile selection and
UI refresh for valid frequencies.

by settings_performance_power_control_title and

to align with the established CPU/GPU frequency-control terminology.

- Around line 2243-2244: Update the power_control_enable_desc Japanese

Use consistent Korean terminology for Power Control.
The existing power_control label at Line 2265 is 성능 제어, but these new strings use 전원 제어. Use 성능 제어 in the new labels so the settings screen and in-game control use the same term.

224-232: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winStop the driver when power control is disabled.
setPowerControlEnabled(false)stops only auto-tuning and fan control. It does not calldriver.stop(). The CPU, GPU, and bus limits written byapplyCurrentProfile()can remain active.resume()also starts the driver whileenablePowerControlis false.Stop the driver on disable. On resume, start and apply the driver only when the active profile enables power control.

Description
Introduces a master switch to enable or disable all in-game power control features. This allows users to prevent the app from taking over CPU/GPU clock management from the OS.
PowerManagernow conditionally activates its features based on this toggle, and the UI reflects this state by hiding/disabling sub-controls when power control is off.PowerManager's lifecycle andPServerDriver's initialization to streamline logic and simplify driver interactions.PID Controllerimplementation logic to give different min / max valuesRecording
