Annotated Snippet
What: /sys/devices/platform/i8042/.../sensitivity
Date: Aug, 2005
KernelVersion: 2.6.14
Contact: linux-input@vger.kernel.org
Description:
(RW) Trackpoint sensitivity.
What: /sys/devices/platform/i8042/.../intertia
Date: Aug, 2005
KernelVersion: 2.6.14

KernelVersion: 2.6.14
Contact: linux-input@vger.kernel.org
Description:
(RW) The drag hysteresis controls how hard it is to drag with
z-axis pressed.

Date: Aug, 2005
KernelVersion: 2.6.14
Contact: linux-input@vger.kernel.org
Description:
(RW) The offset from the running average required to generate a
select (click) on z-axis on release.
What: /sys/devices/platform/i8042/.../ztime
Date: Aug, 2005
KernelVersion: 2.6.14
Contact: linux-input@vger.kernel.org
Description:
(RW) This attribute determines how sharp a press has to be in
order to be recognized.

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
