From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Hutterer Subject: [PATCH v3 0/8] HID: MS and Logitech high-resolution scroll wheel support Date: Wed, 5 Dec 2018 10:42:20 +1000 Message-ID: <20181205004228.10714-1-peter.hutterer@who-t.net> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-input@vger.kernel.org Cc: Dmitry Torokhov , Jiri Kosina , Harry Cutts , torvalds@linux-foundation.org, Nestor Lopez Casado , linux-kernel@vger.kernel.org, Benjamin Tissoires List-Id: linux-input@vger.kernel.org A full explanation of why and what is in the v1, v2 patch thread here: https://lkml.org/lkml/2018/11/22/625 v3 adds a better commit messages, m560 REL_HWHEEL_HI_RES support and a patch moved in the ordering. This is a full patch sequence because Benjamin's magic scripts struggle with singular updates ;) hid-tools patches to add the tests: https://gitlab.freedesktop.org/libevdev/hid-tools/merge_requests/12 libinput support (unmerged): https://gitlab.freedesktop.org/whot/libinput/tree/wip/hi-res-scrolling If you want to 'feel' how it works, run sudo ./builddir/libinput-debug-gui and watch the green/red scroll bars. On a device with hi-res scrolling the green bar (scroll fractions) will move smoother than the red bar (wheel clicks). Tested with: - Microsoft Comfort Optical Mouse 3000 - Microsoft Sculpt Ergonomic Mouse - Microsoft Wireless Mobile Mouse 4000 - Logitech MX Anywhere 2S And a few other mice that don't have that feature, so the testing was of limited excitement.
