References SimObject::name(), and parent.

◆ onNotifyDescriptor()

void VirtIO9PBase::FSQueue::onNotifyDescriptor ( VirtDescriptor desc)

Notify queue of pending incoming descriptor.

This method is called by the default implementation of onNotify() to notify the device model of pending data in a descriptor chain.

Device models should normally overload one of onNotify() and onNotifyDescriptor().

Reimplemented from VirtQueue.
