Member Function Documentation

◆ keyPress()

void gem5::ps2::PS2Keyboard::keyPress	(	uint32_t	key,
		bool	down )

overridevirtual

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

Parameters

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

Implements gem5::VncKeyboard.

Definition at line 182 of file keyboard.cc.

References gem5::ArmISA::c, gem5::ps2::down, enabled, gem5::ps2::keys, gem5::ps2::keySymToPs2(), gem5::ps2::Device::send(), and shiftDown.

◆ recv()

bool gem5::ps2::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

data	Pending input data (at least one byte)

Returns: false if more data is needed to process the current command, true otherwise.

Implements gem5::ps2::Device.

Definition at line 84 of file keyboard.cc.

◆ serialize()

void gem5::ps2::PS2Keyboard::serialize ( CheckpointOut & cp ) const

overridevirtual

Serialize an object.

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

Parameters

cp	Checkpoint state

Reimplemented from gem5::ps2::Device.

References enabled, gem5::ps2::Device::serialize(), SERIALIZE_SCALAR, and shiftDown.

◆ unserialize()

void gem5::ps2::PS2Keyboard::unserialize ( CheckpointIn & cp )

overridevirtual

Unserialize an object.

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

Parameters

cp	Checkpoint state

Reimplemented from gem5::ps2::Device.
