If a link or response timeout occurs in the RapidIO physical layer, is there any indication on the logic layer response port?
There currently is no way for the user to know when the physical layer's timeout register has expired. The only indication that you might get is that the ACK ID counter is rewound to resend the packet, but this could happen for other reasons as well, such as a CRC error.
Currently, our interpretation is that users do not need to know this. However, perhaps we are wrong. We would welcome users' responses concerning why they need to know this, and if appropriate we could potentially add in a functionality to make this information available to the user.
