Debugging of adapters with stateful offload connections

摘要

An approach is provided in which a network hardware adapter stores offload information in a shared memory area that is located on a host system. The offload information includes connection information that was offloaded to the network hardware adapter by an application executing on the host system. An operating system (e.g., a network device driver) detects a network adapter error corresponding to the network hardware adapter and, in turn, retrieves the offload information stored in the shared memory area. As such, an analysis application utilizes the retrieved offload information to debug the network adapter error.

1. A method comprising:
storing offload information, by a network hardware adapter, in shared system memory located on a host system, wherein the offload information was provided by an application and includes connection information corresponding to the application; detecting a network adapter error corresponding to the network hardware adapter; in response to detecting the network adapter error:
retrieving the offload information stored in the shared system memory; anddebugging the network adapter error based upon the retrieved offload information.
