This patch series is focused on improving the compatibility and usability of the hid-pidff force feedback driver. Last patch introduces a new, universal driver for PID devices that need some special handling like report fixups, remapping the button range, managing new pidff quirks and setting desirable fuzz/flat values. This work has been done in the span of the past months with the help of the great Linux simracing community, with a little input from sim flight fans from FFBeast. No changes interfere with compliant and currently working PID devices. I'm not married to the name. It's what we used previously, but if "universal" is confusing (pidff is already the generic driver), we can come up with something better like "hid-quirky-pidff" :) --- Changes in v2: - Fix typo in a comment - Fix a possible null pointer dereference when calling hid_pidff_init_with_quirks especially when compiling with HID_PID=n - Fix axis identifier when updating fuzz/flat for FFBeast Joystick --- Changes in v3: - Fixed a missed incompatible pointer type while assigning hid_pidff_init_with_quirks to init_function pointer (void -> int) - Improved Kconfig entry name to adhere to the alphabetical order of special HID drivers - Extended cover letter --- Changes in v4: - Added PXN devices and their hid ids - Added hid-universal-pidff entry in the MAINTAINERS file --- Changes in v5: - Added PERIODIC_SINE_ONLY quirk Tomasz Pakuła (12): HID: pidff: Convert infinite length from Linux API to PID standard HID: pidff: Do not send effect envelope if it's empty HID: pidff: Clamp PERIODIC effect period to device's logical range HID: pidff: Add MISSING_DELAY quirk and its detection HID: pidff: Add MISSING_PBO quirk and its detection HID: pidff: Add MISSING_DEVICE_CONTROL quirk HID: pidff: Add hid_pidff_init_with_quirks and export as GPL symbol HID: pidff: Add FIX_WHEEL_DIRECTION quirk HID: pidff: Stop all effects before enabling actuators HID: Add hid-universal-pidff driver and supported device ids MAINTAINERS: Add entry for hid-universal-pidff driver HID: pidff: Add PERIODIC_SINE_ONLY quirk MAINTAINERS | 6 + drivers/hid/Kconfig | 14 +++ drivers/hid/Makefile | 1 + drivers/hid/hid-ids.h | 29 +++++ drivers/hid/hid-universal-pidff.c | 191 ++++++++++++++++++++++++++++ drivers/hid/usbhid/hid-pidff.c | 203 ++++++++++++++++++++++-------- include/linux/hid.h | 9 ++ 7 files changed, 404 insertions(+), 49 deletions(-) create mode 100644 drivers/hid/hid-universal-pidff.c -- 2.48.1
