This introduces a new driver for the Xbox One/Series controller protocol, officially known as the Gaming Input Protocol, or GIP for short. Microsoft released documentation on (some of) GIP in late 2024, upon which this driver is based. Though the documentation was incomplete, it still provided enough information to warrant a clean start over the previous, incomplete implementation. This driver is already at feature parity with the GIP support in xpad, along with several more enhancements: - Proper support for parsing message length and fragmented messages - Metadata parsing, allowing for auto-detection on various parameters, including the presence and location in the message of the share button, as well as detection of specific device types - Controllable LED support - HID passthrough for the Chatpad - Preliminary support for racing wheels and flight sticks The framework set out in this driver also allows future expansion for specialized device types and additional features more cleanly than xpad. Future plans include: - Improved support for racing wheels and flight sticks, including force feedback and LED support. - Support for the security handshake, which is required for devices that use wireless dongles. - Exposing a raw character device to enable sending vendor-specific commands from userspace. - Event logging to either sysfs or dmesg. - Support for the headphone jack. Also included in this series is the addition of three new ABS input types, with the two relevant ones to HID added to the mappings Vicki Pfau (6): Input: xbox_gip - Add new driver for Xbox GIP Input: xpad - Remove Xbox One support Input: Add ABS_CLUTCH, HANDBRAKE, and SHIFTER HID: Map more automobile simulation inputs Input: xbox_gip - Add wheel support Input: xbox_gip - Add flight stick support Documentation/input/devices/xpad.rst | 17 +- MAINTAINERS | 6 + drivers/hid/hid-debug.c | 16 +- drivers/hid/hid-input.c | 2 + drivers/input/joystick/Kconfig | 26 + drivers/input/joystick/Makefile | 1 + drivers/input/joystick/xbox_gip.c | 3434 ++++++++++++++++++++++++ drivers/input/joystick/xpad.c | 634 +---- include/uapi/linux/input-event-codes.h | 3 + 9 files changed, 3492 insertions(+), 647 deletions(-) create mode 100644 drivers/input/joystick/xbox_gip.c -- 2.50.1
