Function Documentation

VOID cbmiec_wait_for_listener	(	IN PDEVICE_EXTENSION	Pdx,
		IN BOOLEAN	SendEoi
	)

Wait until listener is ready to receive.

This function waits until a listener is ready.

Parameters

Pdx	Pointer to the device extension.
SendEoi	TRUE if we want to signal an EOI. FALSE otherwise.

Todo:

Shouldn't we make sure that there is no spurious interrupt until now?

Bug:

This implementation can lock up the whole machine, thus, do not use it!
