Abstract
A method for debugging network activity involving receiving, by HCA, a packet stream comprising multiple packets, comparing a packet header of each of the packets to a trigger condition to determine whether the trigger condition has been met, after the trigger condition has been met, comparing each packet header of the packets to one or more trace filters stored in the HCA to identify matching packets, duplicating one or more portions of the matching packets and storing the duplicated portions of the matching packets in a trace buffer, where the trace buffer is located in the HCA and is dynamically repurposed from a payload RAM to the trace buffer when a corresponding port of the HCA for transmitting or receiving the packet stream is set to trace mode, and stopping the trace and copying the one or more portions of packets from the trace buffer to host memory.
