Fix fps limiter - #1861

…on dxvk and opengl games, removed odin 3 from auto power control
Reverts PresentExtension.java to master; the vsync-locked idle pacing moves to its own branch for a staged rollout.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Complete cleanup when runCycle() disables the controller.
When PowerManager.setPowerControlEnabled(false) updates the profile, this branch sets running = false and restores the cap. It does not close sessionLog or clear loopThread, unlike shutdown(). The loop also sleeps once before it exits.
Use a worker-safe shutdown path here. It must close the session log and clear the thread reference without joining the current thread.

Migrate persisted profiles before relying on the new default.
PowerManager uses encodeDefaults = true and restores the stored profile directly. Profiles saved before this change contain enableAdaptiveFpsCap: true, so deserialization does not evaluate this new default. Upgraded Odin 3 users can therefore still start adaptive FPS control through PowerManager.autoStart() and PowerManager.resume().
Add a schema migration or an explicit opt-in marker. Apply the device-gated default to legacy implicit values, but preserve a deliberate user choice.

Android View.getDisplay refresh rate display changed DisplayManager.DisplayListener official documentation
💡 Result:
To detect display refresh rate changes in Android, you should use the DisplayManager.DisplayListener interface [1][2][3]. While the onDisplayChanged(int displayId) method of DisplayManager.DisplayListener is triggered for general display property changes (like size or density), it is specifically noted in official documentation that this callback can also be triggered when the display's refresh rate changes [1][3]. However, because refresh rates can change very frequently, the system provides a specific event flag to subscribe to these updates efficiently [1][3]. To explicitly monitor refresh rate changes, use the registerDisplayListener method that accepts an event filter [1][3]. You should register for the EVENT_TYPE_DISPLAY_REFRESH_RATE event (or the corresponding flag, depending on your API level) [1][4][3]. This ensures your application is only notified when the refresh rate specifically changes, rather than receiving callbacks for every property change [1][3]. When the onDisplayChanged callback is received, you can retrieve the updated refresh rate by calling Display.getRefreshRate on the display object associated with the provided displayId [1][3]. Key implementation details: 1. Registration: Use DisplayManager.registerDisplayListener(Executor, long, DisplayManager.DisplayListener) to subscribe to the EVENT_TYPE_DISPLAY_REFRESH_RATE event [1][3]. 2. Callback: Implement onDisplayChanged(int displayId) within your DisplayListener to handle the event [2][3]. 3. Retrieval: Within the callback, obtain the current display using DisplayManager.getDisplay(displayId) and query the refresh rate using Display.getRefreshRate [1][5][3]. For further details on performance optimization and handling frame rate switches, refer to the official Android documentation on frame rate management [6].

Update SHM pacing when the display refresh rate changes.
LaunchedEffect(xServerView) updates ShmFramePacer only when the view instance changes. A refresh-rate change with the same view can leave ShmFramePacer.periodNs stale, so MITSHMExtension.framePresented() can apply the wrong pacing delay. Update it from a DisplayManager.DisplayListener callback and cover the change in an instrumentation test.

P3: The DeviceGate check is always false in this driver: DeviceGate.testedModels only lists Retroid Pocket 6 and Retroid Pocket Nova, and this profile is only built on Samsung hardware via getDefaultProfile(). So adaptiveFpsCapEnabled is unconditionally false here, which hides the intended "disabled by default" decision behind a gate that can never be true and is already PowerProfile's own default. Set it explicitly to false (or drop the line) so the intent is clear.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Use one predicate for adaptive FPS enablement.
The quick-menu toggle and the autoStart, resume, profile-update, and cycle paths can enable adaptive FPS from adaptiveFpsCapEnabled alone. This allows the cap to run while power control is disabled or on unsupported/Odin 3 devices, and can leave it active after power control is turned off.
Use the same power-control and device-support predicate for the UI and every controller transition, and stop the controller whenever either condition becomes false.

There was a problem hiding this comment.
Not necessary to guard driver.start() to inside power control enabled, applyCurrentProfile already did this. And as pause() stopping the driver, you will need to do driver.start() on resume()
And please check dirver.start() in PServer whether you want to adjust armSessionBaseline(), the start() in PServer is to re-init the newSingleThreadExecutor which is necessary.
pause() always stops the driver, so resume() must always restart it or the PServer executor stays dead after a background/foreground cycle on sessions without power control. applyCurrentProfile() already gates the clock writes itself, and PServerDriver.start()'s armSessionBaseline() is idempotent per session.
