Mon, 20 Jul 2026 05:15:49 +0200

HID: hid-msi: Add Rumble Intensity AttributesAdds intensity adjustment for the left and right rumble motors.Claude was used during the reverse-engineering data gathering for thisfeature done by Zhouwang Huang. As the code had already been affected,I used Claude to create the initial framing for the feature, then didmanual cleanup of the _show and _store functions afterwards to fix bugsand keep the coding style consistent. Claude was also used as an initialreviewer of this patch.Assisted-by: Claude:claude-sonnet-4-6Co-developed-by: Zhouwang Huang Signed-off-by: Zhouwang Huang Link: https://patch.msgid.link/20260529072111.7565-5-derekjohn.clark@gmail.comSigned-off-by: Derek J.

f27e2e3c80edb2ff09c3bb3ee1605c86c64fcaa8 - HID: hid-msi: Add RGB control interface

Mon, 20 Jul 2026 05:15:48 +0200

HID: hid-msi: Add RGB control interfaceAdds RGB control interface for MSI Claw devices. The MSI Claw uses afairly unique RGB interface. It has 9 total zones (4 per joystick ringand 1 for the ABXY buttons), and supports up to 8 sequential frames ofRGB zone data. Each frame is written to a specific area of MCU memory bythe profile command, the value of which changes based on the firmware ofthe device. Unlike other devices (such as the Legion Go or the OneXPlayerdevices), there are no hard coded effects built into the MCU. Instead,the basic effects are provided as a series of frame data. I havemirrored the effects available in Windows in this driver, while keepingthe effect names consistent with the Lenovo drivers for the effects thatare similar.Initial reverse-engineering and implementation of this feature was doneby Zhouwang Huang. I refactored the overall format to conform to kerneldriver best practices and style guides. Claude was used as an initialreviewer of this patch.Assisted-by: Claude:claude-sonnet-4-6Co-developed-by: Zhouwang Huang Signed-off-by: Zhouwang Huang Link: https://patch.msgid.link/20260529072111.7565-4-derekjohn.clark@gmail.comSigned-off-by: Derek J.

93ff13ed1c4b49e0574e92dfb2f833e10ba88e5e - HID: hid-msi: Add M-key mapping attributes

Mon, 20 Jul 2026 05:15:47 +0200

HID: hid-msi: Add M-key mapping attributesAdds attributes that allow for remapping the M-keys with up to 5 valueswhen in macro mode. There are 2 mappable buttons on the rear of thedevice, M1 on the right and M2 on the left. When mapped, the events willfire from one of three event devices: gamepad buttons will fire from thedevice handled by xpad, while keyboard and mouse events will fire fromrespectively typed evdevs provided by the input core. Names of eachmapping have been kept as close to the event that will fire from the evdevas possible, with context added to the ABS_ events on the direction of themovement.Initial reverse-engineering and implementation of this feature was doneby Zhouwang Huang. I refactored the overall format to conform to kerneldriver best practices and style guides.

a9517958e828429ffd88558a8dae80f49f8cfbea - HID: hid-msi: Add MSI Claw configuration driver

Mon, 20 Jul 2026 05:15:46 +0200

HID: hid-msi: Add MSI Claw configuration driverAdds configuration HID driver for the MSI Claw series of handheld PC's.In this initial patch add the initial driver outline and attributes forchanging the gamepad mode, M-key behavior, and add a WO reset function.Sending the SWITCH_MODE and RESET commands causes a USB disconnect inthe device. The completion will therefore never get hit and would triggeran -EIO. To avoid showing the user an error for every write to theseattrs a bypass for the completion handling is introduced when timeout ==0.The initial version of this patch was written by Denis Benato, whichcontained the initial reverse-engineering and implementation for thegamepad mode switching. This work was later expanded by Zhouwang Huangto include more gamepad modes. Finally, I refactored the drivers datain/out flow and overall format to conform to kernel driver bestpractices and style guides. Claude was used as an initial reviewer ofthis patch.Assisted-by: Claude:claude-sonnet-4-6Co-developed-by: Denis Benato Signed-off-by: Denis Benato Co-developed-by: Zhouwang Huang Signed-off-by: Zhouwang Huang Signed-off-by: Derek J.
