This patch supports all three, and uses the multiplier reported by the mouse for the HID++ 2.0+ features. The full list of product IDs of mice which support high-resolution scrolling was provided by Logitech, but the patch was tested using the following mice (using the Unifying receiver): * HID++ 1.0: Anywhere MX, Performance MX * x2120: M560 * x2121: MX Anywhere 2, MX Master 2S This patch is a combinations of the now-reverted commits 1ff2e1a44e0, d56ca9855bf9, 5fe2ccbef9d, 044ee89028 together with some extra bits for the directional and timeout-based reset. The previous patch series was in hid-input, it appears this remainder handling is logitech-specific and was moved to hid-logitech-hidpp.c and renamed accordingly. Signed-off-by: Harry Cutts Signed-off-by: Peter Hutterer --- Changes to the previous version: - this is a squash of the commits above, splitting it up after all the changes was a tad difficult - this looks to be a logitech-specific requirement because the firmware can swallow events. I moved the lot to the hidpp implementation - added directional reset together with the threshold-based REL_WHEEL emulation trigger - added a timeout to stop the emulation from sliding too much within the window This was tested on an MX Anywhere 2S, Harry, please re-test on the other mice, thanks. drivers/hid/hid-logitech-hidpp.c | 310 ++++++++++++++++++++++++++++++- 1 file changed, 306 insertions(+), 4 deletions(-) diff --git a/drivers/hid/hid-logitech-hidpp.c b/drivers/hid/hid-logitech-hidpp.c index 67ca587aecfa..8d2a7000bf0c 100644 --- a/drivers/hid/hid-logitech-hidpp.c +++ b/drivers/hid/hid-logitech-hidpp.c @@ -21,6 +21,7 @@ #include #include #include +#include #include #include #include @@ -64,6 +65,14 @@ MODULE_PARM_DESC(disable_tap_to_click, #define HIDPP_QUIRK_NO_HIDINPUT BIT(23) #define HIDPP_QUIRK_FORCE_OUTPUT_REPORTS BIT(24) #define HIDPP_QUIRK_UNIFYING BIT(25) +#define HIDPP_QUIRK_HI_RES_SCROLL_1P0 BIT(26) +#define HIDPP_QUIRK_HI_RES_SCROLL_X2120 BIT(27) +#define HIDPP_QUIRK_HI_RES_SCROLL_X2121 BIT(28) + +/* Convenience constant to check for any high-res support. */ +#define HIDPP_QUIRK_HI_RES_SCROLL (HIDPP_QUIRK_HI_RES_SCROLL_1P0 | \ + HIDPP_QUIRK_HI_RES_SCROLL_X2120 | \ + HIDPP_QUIRK_HI_RES_SCROLL_X2121) #define HIDPP_QUIRK_DELAYED_INIT HIDPP_QUIRK_NO_HIDINPUT @@ -128,6 +137,31 @@ struct hidpp_battery { bool online; }; +/** + * struct hidpp_scroll_counter - Utility class for processing high-resolution + * scroll events. + * @dev: the input device for which events should be reported. + * @wheel_multiplier: the scalar multiplier to be applied to wheel + * data as a fraction of 120.
