Subject: [PATCH] hid-asus-ally: Add full gamepad support
This driver adds full support of the ASUS ROG Ally X gamepad and support
for the Ally 1 xpad configuration options.
- dinput is translated to XBox controller (Ally-X only)
- default mode has the QAM buttons mapped (Ally-X only)
* left is XBox button
* right is an XBox + A combo for steam QAM
- force feedback is supported (Ally-X only)
- LED brightness control (0-3)
- LED multicolor class support
- Support all configuration
The configuration options available are:
- Gamepad mode (game, wasd, mouse)
- Remapping each button, plus macro map (hold macro btn and press other)
- Joystrick and trigger deadzones
- Gamepad vibration intensity
- Leds (using multicolor class)
- Button turbo abilities (per button)
- Joystick repsonse curves
- Joystick anti-deadzones
The attribute path tree looks like this:
- `./sys/../<USB HID>/`
- `joystick_left/
- `deadzone`
- `mapping` (mouse, wasd, custom)
- `anti_deadzone`
- `response_curve`
- `calibration`
- `calibration_reset`
- `trigger_left/
- `deadzone`
- `response_curve`
- `calibration`
- `calibration_reset`
- `gamepad_mode`
- `button_mapping`
- `A`
- `B`
- `dpad_left`
- etc
No settings are applied until `apply_all` is written to. The exception is
for calibrations.
While there is calibration ability, it can be difficult to get correct
and is heavily device dependent, as such it is set when written and not
when `apply_all` is written to. On driver load the set calibrations are
retrieved - this may be what you've set in Linux, Windows, or factory
defaults.
This patch provides an excellent default experience for the Ally X
device while the Ally 1 is a little more limited due to Xinput being
used.
