[PATCH v27 0/7] MR7422: winebus/dinput: Support arbitrary number of axes in the virtual PID descriptor
Related Wine issue: https://bugs.winehq.org/show_bug.cgi?id=52714 I'm starting work on updating/extending Linux force feedback API and one of my goals is to expose the number and an array that contains the device's ffb-enabled axes. As I'm mainly working with USB PID driver, I already have a POC of obtaining this data. What prompted this is that currently Wine always creates virtual joysticks with two PID ffb axes. This causes issues with [Richard Burns Rally](https://github.com/ValveSoftware/Proton/issues/6702#issuecomment-2670946977), as this game incorrectly initializes a `CONSTANT_FORCE` effect with all the FFB axes that contain `DIDOI_FFACTUATOR` flag and then trying to update `cAxes` and `rgdwAxes` values which leads to `DIERR_INVALIDPARAM`. Now, this flag is set by wine while enumerating virtual device's axes and while `(axis index < FFB axes)`, flag is applied. This means, that every device which has FFB functionality and at least two axes, will report FFB on `X`, `Y`. While updated API would mean a lot of steering wheels would correctly report only 1 axis, a lot of USB PID wheels still include `X` and `Y` in their `AXES_ENABLE` and `DIRECTION` usages. This, again, would lead to broken FFB (in affected games). On Windows, there's a possibility of overwriting some joystick capabilities with registry entries, which ends up removing `DIDOI_FFACTUATOR` flag from a selected axis. This doesn't work in Wine. This MR allows Wine to add an arbitrary number (up to `PID_AXES_MAX`) of axes to the PID descriptor, based on the value of Haptic Axes from SDL or from Linux FF api in the future (I'm working on it). Additionally, to work around RBR and other games with similar, wrong FFB handling, I introduced a [hint](https://github.com/libsdl-org/SDL/issues/12341) to SDL that allows a dynamic overwrite of the number of haptic axes. For the Linux API, I'll figure out a nice way to override when the number of axes will be exposed. With these changes, I was able to successfully get force feedback on my Moza Racing R9 with all axes usable. With additional traces in the dinput code, I confirmed that with one axis defined in the PID descriptor, the game created a constant force effect with just one axis and `cAxes = 1`. -- v27: https://gitlab.winehq.org/wine/wine/-/merge_requests/7422

From: Tomasz Pakuła <tomasz.pakula.oficjalny(a)gmail.com> Wine will now create PID axes in the virtual descriptor based on the haptic axes found in the SDL joystick. With the recent SDL hint SDL_JOYSTICK_HAPTIC_AXES, it's possible to limit the exposed FFB axes to just one, even if device presents more. This, in turn fixes force feedback in Richard Burns Rally which includes all ffb axes on effect creation, but then updates this effec with only the steering axis. Changing cAxes and rgdwAxes after effect creation is forbidden and renders force feedback broken. This issue is not wine-specific as the same thing happens on Windows for all steering wheels which define more than one FFB axis. On windows, this can be worked around with registry hacks which remove DIDFT_FFACTUATOR and DIDOI_FFACTUATOR from second axis dwType and dwFlags.
