Member Function Documentation

add_handler()

void IORegDispatcher::add_handler ( IORegHandler &  handler )

inline

ioreg_peek_handler()

virtual uint8_t IORegDispatcher::ioreg_peek_handler ( reg_addr_t  addr, uint8_t  value  )

inlineoverridevirtual

Callback for a I/O peek access. On-the-fly modifications of the register content are possible.

Parameters

addr	address of the register read, in I/O address space
value	current cached value of the register

Returns

actual value of the register

Implements IORegHandler.

ioreg_read_handler()

virtual uint8_t IORegDispatcher::ioreg_read_handler ( reg_addr_t  addr, uint8_t  value  )

inlineoverridevirtual

Callback for a CPU I/O read access. On-the-fly modifications of the register content are possible.

Parameters

addr	address of the register read, in I/O address space
value	current cached value of the register

Returns

actual value of the register

Implements IORegHandler.

ioreg_write_handler()

virtual void IORegDispatcher::ioreg_write_handler ( reg_addr_t  addr, const ioreg_write_t &  data  )

inlineoverridevirtual

Callback for a CPU I/O write access. Note that the register has already been updated so it's ok for the callback to overwrite it. (a typical use case is implementing write-one-to-clear bits)

Parameters

addr	address of the register read, in I/O address space
data	struct containing the data change.

Implements IORegHandler.
