Replace the keyboard driver's synthetic stream with the real path: - ps2-bus binds IRQ1 (interrupt bits set only after the bind), drains port 0x60 on each interrupt, and forwards every byte to the attached child driver over async ipc_send, routed by the status register's auxiliary-output bit. Children attach via the new well-known ps2_bus service, handing over their endpoint as a capability. - scancode.zig (new, pure, host-tested): scancode set 2 -> USB HID usage decoding (F0/E0/E1 prefix state machine) plus keyboard state — pressed-key bitmap, typematic-repeat classification, modifier and caps-lock tracking. - keyboard.zig decodes the forwarded stream and publishes real key_down/key_press/key_up events, filling key_press characters via xkeyboard-config (layout from argv[2], default us) and synthesizing ASCII control characters for Enter/Tab/Backspace/Escape. - protocol.zig names the full HID usage set in Keycode; build.zig threads the xkeyboard-config module into user binaries. Verified end to end in QEMU via monitor sendkey: shift, caps lock, and control-character synthesis all decode correctly. The mouse driver still publishes its synthetic stream; attaching it to the bus the same way is the follow-up. |
