From Harry Cutts <> Subject [PATCH v2 0/5] Add support for high-resolution scrolling on Logitech mice Date Thu, 30 Aug 2018 14:56:17 -0700 Hi everyone,



This is v2 of the patch set adding support for high-resolution scroll

wheels on Logitech mice. 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,

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
