HID: pidff: Move all hid-pidff definitions to a dedicated header

HID: pidff: Add PERIODIC_SINE_ONLY quirk

2025-04-20T08:17:38Z

[ Upstream commit abdbf8764f4962af2a910abb3a213ecf304a73d3 ] Some devices only support SINE periodic effect although they advertise support for all PERIODIC effect in their HID descriptor. Some just do nothing when trying to play such an effect (upload goes fine), some express undefined behavior like turning to one side. This quirk forces all the periodic effects to be uploaded as SINE. This is acceptable as all these effects are similar in nature and are mostly used as rumble. SINE is the most popular with others seldom used (especially SAW_UP and SAW_DOWN).

HID: pidff: Add FIX_WHEEL_DIRECTION quirk

2025-04-20T08:17:38Z

[ Upstream commit 3051bf5ec773b803c474ea556b57d678a8885be3 ] Most steering wheels simply ignore DIRECTION field, but some try to be compliant with the PID standard and use it in force calculations. Games often ignore setting this field properly and/or there can be issues with dinput8 -> wine -> SDL -> Linux API translation, and this value can be incorrect. This can lead to partial/complete loss of Force Feedback or even unexpected force reversal. Sadly, this quirk can't be detected automatically without sending out effects that would move an axis. This fixes FFB on Moza Racing devices and others where effect direction is not simply ignored.

HID: pidff: Add hid_pidff_init_with_quirks and export as GPL symbol

2025-04-20T08:17:38Z

[ Upstream commit 36de0164bbaff1484288e84ac5df5cff00580263 ] This lays out a way to provide an initial set of quirks to enable before device initialization takes place. GPL symbol export needed for the possibility of building HID drivers which use this function as modules. Adding a wrapper function to ensure compatibility with the old behavior of hid_pidff_init.

HID: pidff: Add PERMISSIVE_CONTROL quirk

2025-04-20T08:17:38Z

[ Upstream commit a4119108d2530747e61c7cbf52e2affd089cb1f6 ] With this quirk, a PID device isn't required to have a strict logical_minimum of 1 for the the PID_DEVICE_CONTROL usage page. Some devices come with weird values in their device descriptors and this quirk enables their initialization even if the logical minimum of the DEVICE_CONTROL page is not 1.

HID: pidff: Add MISSING_PBO quirk and its detection

[ Upstream commit fc7c154e9bb3c2b98875cfc565406f4787e3b7a4 ] Some devices with only one axis are missing PARAMETER_BLOCK_OFFSET field for conditional effects. They can only have one axis, so we're limiting the max_axis when setting the report for those effects. Automatic detection ensures compatibility even if such device won't be explicitly defined in the kernel. Fixes initialization of VRS DirectForce PRO and possibly other devices.

Merge branch 'for-6.13/bpf' into for-linus

2024-11-18T21:02:17Z

- improvement of the way hid-bpf coexists with specific drivers (others than hid-generic) that are already bound to devices (Benjamin Tissoires)

HID: add per device quirk to force bind to hid-generic

2024-10-04T14:10:46Z

We already have the possibility to force not binding to hid-generic and rely on a dedicated driver, but we couldn't do the other way around. This is useful for BPF programs where we are fixing the report descriptor and the events, but want to avoid a specialized driver to come after BPF which would unwind everything that is done there.
