ps2: pre-init key events may result in messed-up key state #4758

Closed chelmuth closed 1 month ago

chelmuth commented 1 year ago

Similar to #4604 after booting Fujitsu Lifebook U7411, on-boot key events mess up the key state because of press events without releases (some queue overflow in the firmware?). The situation can be reproduced by press-and-hold of a key during boot (GRUB phase) and release on first Genode boot messages.

May the driver need to trigger a special flush of pending events beyond the current data flush in https://github.com/genodelabs/genode/blob/25eac6b9e6fe3d0164e010cabc76a82fa7901601/repos/os/src/drivers/ps2/x86/i8042.h#L282-L318?

@Cochimetl may you check if commit f86bba3059c813bd6c28ec53c56760318d2ea653 also fixes this issue?

The issue is not reproducible since release 24.05.
