Classify configured devices by keyboard and pointer capability so
automatic keyboard capture leaves relative pointer devices with the
display server.
Run descriptor, grab, physical-state, and LED operations on one worker.
Marshal normalized events through each display server's event loop and
serialize ownership changes with per-lane barriers.
Fall back whole lanes to native input when an evdev cohort cannot be
owned, and retry missing or removed devices without disabling the rest.
Handle report framing, SYN_DROPPED, high-resolution wheels, queue
overflow, held-state cleanup, and guest-driven keyboard LEDs. Restore
host LEDs and kernel grabs during teardown.
Re-evaluate capture when the active input transport changes.
Report guest HID keyboard LED state from LGInput to LGIdd and
publish it with the LGMP input endpoint status.
Forward SPICE modifier updates through the same provider state so evdev
can synchronize physical keyboard LEDs across transport changes and
reconnects.
Bump the versioned pipe and KVMFR input status contracts for the new
feedback state.
Accept earlier LGMP input status versions without LED feedback so the
client retains input while the guest driver is being upgraded.
Introduce LG_InputOps and route keyboard and mouse input through the
active video transport when it provides an input backend.
Keep SPICE as the fallback and force it while the SPICE display is
active. Add atomic shared/exclusive locking for safe backend changes.
