evdev: use a prometheus-safe label for ev_sysctl_tree

2026-06-30T16:51:57Z

Prometheus doesn't allow spaces, let's normalize this to what we use elsewhere for consistency. The sysctl exporter could probably do this itself, but let's decouple that from the immediate problem: matching the label between the exported data and in-tree is nice for greppability.

evdev: add devnum sysctl

2026-06-14T16:34:51Z

Add a sysctl entry for the evdev device number (devnum) to allow libudev-devd to populate the corresponding device information fields (MAJOR and MINOR) when running in a jail with no input devices exposed through devfs.

sysmouse(4): Add wsp(4)-style T-Axis reporting.

2025-03-07T17:53:35Z

Neither the ums(4) nor psm(4) reporting can be used by the wsp(4) driver, as they rely on static-length movements, while wsp(4) may need to scroll in large amounts per evdev event push. This style uses a false button-5 press as an indicator that the z-axis movement is a horizontal scroll, otherwise a vertical scroll. Signed-off-by: Joshua Rogers

of various keyboard drivers. EVIOCGRAB ioctl execution on /dev/input/event# device node gains exclusive access to this device to caller. It is used mostly for development purposes and remote control software. See e.g. https://reviews.freebsd.org/D30020 which is the reason of creation of this change. Keyboard grabbing is disabled in KDB and during panics. MFC with: 4a0db5e2920c Tested by: corvink Differential revision: https://reviews.freebsd.org/D30542

evdev: Add implicit mode for touch tracking.

2021-08-24T22:52:37Z

In implicit mode assignment of slot number and tracking id is performed automatically on each synchronization requested by device driver. This is done with creation of intermediate buffer for multitouch events. This buffer holds untracked events until synchronization is requested by device driver. It is needed as touch assigment requires knowledges of all touch positions pushed in current and previous reports. MFC after: 2 weeks
