//! test/system/services/input-source — a hardware-free synthetic input source, used to exercise
|
|
//! the input service end to end without a real PS/2 controller (the `input` test case, and
|
|
//! any bring-up where there is no hardware). It stands in for a driver: it connects to the
|
|
//! input service and publishes a rolling stream that cycles through all device classes —
|
|
//! keyboard, mouse, and joystick/gamepad — which the service routes to interested
|
|
//! subscribers.
|
|
//!
|
|
//! It stays silent after startup (no per-event logging) so it can share the boot serial
|
|
//! transcript with a subscriber whose output is the test's success marker. The real
|
|
//! keyboard and mouse drivers publish their own synthetic streams today; swapping in
|
|
//! decoded hardware is a follow-up (see docs/input.md).
