func (*I8042) WriteIOPort ¶
WriteIOPort implements chipset.PortIOHandler.
type OutputBufferState ¶
type OutputBufferState uint8
OutputBufferState tracks what device owns the output buffer
const ( OutputBufferEmpty OutputBufferState = iota OutputBufferController OutputBufferKeyboard OutputBufferMouse )
type PS2Keyboard ¶
type PS2Keyboard struct {
// contains filtered or unexported fields
}
PS2Keyboard implements a PS/2 keyboard device.
func NewPS2Keyboard ¶
func NewPS2Keyboard() *PS2Keyboard
