Cache native keyboard lock state across input-provider transitions and
reconcile it with HID LED feedback over LGMP.
Project raw and corrective lock-key transitions through the reliable
input FIFO, defer correction until outstanding transitions settle, and
recover from delayed or missing feedback without double toggling.
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.
evdev_stop was never called, and calling it revealed unsafe teardown:
the device list was freed before the thread was joined, a zero epoll
descriptor was mistaken for a valid one, and the device loops walked
past the end of the array through a sentinel that does not exist.
Join the thread in evdev_stop and defer the rest to the new evdev_free.
The display server grab hooks route into evdev until its event thread
is joined, so the device state must stay valid until the display
server has been freed; evdev_free then restores the hooks and releases
the state.
Treat autoCapture as keyboard ownership while the pointer is inside the
guest viewport. Predict the next local position for both absolute and
relative motion, then release the keyboard before the pointer crosses
an edge.
Keep capture, focus, and deferred evdev transitions consistent while
retaining the latest local position as the prediction baseline.
Map the remaining Linux mouse buttons through Wayland and evdev.
Use one X11 translation for cooked and raw press and release events.
Ignore unsupported horizontal scrolling and extended SPICE buttons.
The new configuration option `input:evdev` accepts a comma separated
list of `/dev/input/` keyboard devices to use for input when in capture
mode. This makes it possible to capture only a specific keyboard instead
of all keyboards.
