Performing network core dump without drivers

摘要

Core dump is performed over a network without relying on network device drivers. Instead of network device drivers, firmware of network devices that is typically used during boot is preserved in memory post-boot, and one or more application program interfaces of the firmware are invoked to perform the network core dump. For ease of implementation, a network bootstrap program that has standard application program interfaces for calling into the firmware of network devices may be invoked when performing core dump over the network.
