Member Function Documentation

◆ keyPress()

void PS2Keyboard::keyPress ( uint32_t  key,
bool  down 
)
overridevirtual

Called when the vnc server receives a key press event from the client.

Parameters
keythe key passed is an x11 keysym
downis the key now down or up?

Implements VncKeyboard.

Definition at line 156 of file keyboard.cc.

References ArmISA::c, Ps2::down, enabled, Ps2::keys, Ps2::keySymToPs2(), PS2Device::send(), and shiftDown.

◆ recv()

bool PS2Keyboard::recv ( const std::vector< uint8_t > &  data)
overrideprotectedvirtual

Data received from host.

Data sent to the device is buffered one byte at a time. Each time a byte is added, this function is called and passed the current buffer. It should return true if it has consumed the data and the buffer can be cleared, or false if more data is needed to process the current command.

Parameters
dataPending input data (at least one byte)
Returns
false if more data is needed to process the current command, true otherwise.

Implements PS2Device.

◆ serialize()

void PS2Keyboard::serialize ( CheckpointOut cp) const

Serialize an object.

Output an object's state into the current checkpoint section.

Parameters

◆ unserialize()

void PS2Keyboard::unserialize ( CheckpointIn cp)
overridevirtual

Unserialize an object.

Read an object's state from the current checkpoint section.

Parameters
cpCheckpoint state

Reimplemented from PS2Device.
