A variable controlling whether extended input reports should be used for PS4 controllers when using the HIDAPI driver.
Defined in SDL_hints.h
#define SDL_HINT_JOYSTICK_HIDAPI_PS4_RUMBLE "SDL_JOYSTICK_HIDAPI_PS4_RUMBLE"
This variable can be set to the following values:
Extended input reports allow rumble on Bluetooth PS4 controllers, but break DirectInput handling for applications that don't use SDL.
Once extended reports are enabled, they can not be disabled without power cycling the controller.
For compatibility with applications written for versions of SDL prior to the introduction of PS5 controller support, this value will also control the state of extended reports on PS5 controllers when the SDL_HINT_JOYSTICK_HIDAPI_PS5_RUMBLE hint is not explicitly set.
