See the linux-input "Reporting high-resolution scroll events" thread [0] for previous discussion of the evdev changes. I would love to hear your feedback. Thanks, Harry Cutts Chrome OS Touch/Input team [0]: https://www.spinics.net/lists/linux-input/msg57380.html Changes in v2: * Changed the REL_WHEEL_HI_RES code to use micrometres (a.k.a. microns) as its units, instead of 256ths of a millimetre. * Removed support for mice connecting over Bluetooth, due to a bug where the mouse's high-res mode and the driver's settings get out of sync when the mouse is power cycled. * Moved the creation of the HID++ 1.0 function and the refactor to use the LDJ_DEVICE macro into separate patches. * Added a couple of explanatory comments to the Logitech driver. Harry Cutts (5): Add the `REL_WHEEL_HI_RES` event code Create a utility class for counting scroll events Add function to enable HID++ 1.0 "scrolling acceleration" Enable high-resolution scrolling on Logitech mice Use LDJ_DEVICE macro for existing Logitech mice Documentation/input/event-codes.rst | 11 +- drivers/hid/hid-input.c | 45 ++++ drivers/hid/hid-logitech-hidpp.c | 311 ++++++++++++++++++++++--- include/linux/hid.h | 28 +++ include/uapi/linux/input-event-codes.h | 1 + 5 files changed, 368 insertions(+), 28 deletions(-) -- 2.19.0.rc0.228.g281dcd1b4d0-goog
