Show the active controller polling rate in Controller tab

[NicholasBly]

Appends the controller's active polling rate to the "Assigned:" line in Controller settings, and if the user's active controller is a PS5 Dualsense/Dualsense Edge, it will show a small prompt that hidusbf can be used to bump it up to 1000hz for max performance (if it's not currently running at 1000hz - default out of the box is 250hz). If you don't want that label feel free to remove.

SDL's reported rate is hard-coded by device type in SDL_hidapi_ps5.c (250 Hz over USB), so it reads 250 Hz even when hidusbf has the controller at 1000 Hz. The rate is measured instead from the device-clocked sensor_timestamp on accelerometer events, which SDL posts once per HID report.

The accelerometer is only enabled when the Controller settings menu is open, and only switched off again if it was enabled here, since Wii Remote motion shares it.

Summary by CodeRabbit

• New Features
  • Controller settings display a measured polling rate when available, including for newly connected controllers while the settings remain open.
  • Wired PS5 controllers reporting a rate below 900 Hz show a note about hidusbf.
  • Polling-rate collection stops when you leave Controller settings, and sensors enabled for measurement are turned off afterward.

📝 Walkthrough

Walkthrough

The controller settings overlay measures gamepad polling rates from accelerometer sensor events. It manages sensor collection, calculates rates from event timestamps, and displays available measurements, including a note for certain wired PS5 controllers.

Changes

Controller polling-rate measurement

Layer / File(s)	Summary
Sensor lifecycle and rate calculation runtime/src/settings_overlay.cpp	The overlay tracks accelerometer sensor ownership and uses event timestamps to calculate per-gamepad polling rates. It restarts the measurement window when timestamps do not increase and calculates a rate after at least 250 ms.
Controller settings integration runtime/src/settings_overlay.cpp	Controller settings request polling-rate collection and display an available rate. Draw updates sensor collection, and the label adds a hidusbf note for wired PS5 controllers reporting below 900 Hz.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: 🔵 Low · up to a247a

Wired PS5 controllers measured at 900–999 Hz still show their rate but miss the hidusbf prompt. This is a bounded issue that can be fixed or accepted before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 77fd2

Closing controller settings can disable an accelerometer that Wii Remote motion input has since started using. This could interrupt motion input until the sensor is enabled again. The change does not appear to introduce a new network or privileged operation.

Retained concerns

• Medium · reliability · inferred: If polling enables an accelerometer before Wii Remote input starts using it, closing controller settings can disable the sensor while Wii input still depends on it. Wii input's recorded gamepad ID then prevents its normal enable path from retrying for that device.
• Low · reliability · inferred: If disabling a sensor fails when polling stops, the overlay clears its ownership record anyway. A later session sees the sensor enabled and does not reclaim it, so ordinary stop processing will not retry cleanup.

Security review details

Security Blast Radius

• inferred — The demonstrated effect is confined to gamepad sensors and local runtime input behavior. The examined polling path does not route sensor values to a privileged or external sink.

Trust Boundaries and Controls

• observed — Sensor updates originate from SDL gamepad events, but the added measurement branch is gated on active controller-settings collection. Sensor enablement is limited to supported, previously disabled gamepads; that check protects consumers already active when collection starts, not consumers that begin later.

Resilience and Maintainability Implications

• inferred — Independent ownership records allow a later Wii consumer to lose sensor data on overlay cleanup; unconditional ownership clearing also prevents retrying a failed disable. Both weaken containment of sensor lifecycle failures.

Hardening Proposals

• proposed — Coordinate accelerometer use across the overlay and Wii input, or revalidate active consumers before disabling a sensor. Retain cleanup state when a disable fails so it can be retried.

Inline comments:
In `@runtime/src/settings_overlay.cpp`:
- Line 780: Update the hz threshold in the gamepad prompt condition to 1000 so
wired PS5 controllers measured below 1000 Hz receive the prompt.
- Line 753: Update the polling-rate guard using g_pollRateWanted and
g_pollRateActive so it does not skip sensor discovery while collection remains
active. Scan newly available gamepads and retry enabling sensors that previously
failed, including devices with new SDL instance IDs after reconnection; preserve
the existing polling-rate update behavior.
- Around line 753-773: Update UpdatePollRateSensors() cleanup so it does not
disable an owned accelerometer when its gamepad belongs to an active Wii Remote.
Check active remote channels and match their gamepad IDs before calling
SDL_SetGamepadSensorEnabled; keep cleanup unchanged for other gamepads.
