receivePacket

Debugger polled-mode receive handler.

Declaration

virtual void receivePacket(
 void *pkt,
 UInt32 *pktSize,
 UInt32timeout);

Parameters

  • pkt:

    Address of a receive buffer where the received packet should be stored. This buffer has room for 1518 bytes.

  • pktSize:

    Address where the number of bytes received must be recorded. Set this to zero if no packets were received during the timeout interval.

  • timeout:

    The maximum amount of time in milliseconds to poll for a packet to arrive before this method must return.

Overview

This method must be implemented by a driver that supports kernel debugging. After a debugger client has been attached through attachDebuggerClient(), this method will be called by the debugger client to poll for an incoming packet when the kernel debugger is active. This method may be called from the primary interrupt context, and the implementation must avoid any memory allocation, and must never block. The receivePacket() method in IONetworkController is used as a placeholder, it performs no useful action, and should not be called. A driver that attaches a debugger client must override this method.
