PCIe DPC SMI storm prevention system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide an initialization engine that is configured to:
• receive, in response to an error being experienced in a first PCIe device, a plurality of interrupts that are each configured to initiate an error handling mode;
• track a number of the plurality of interrupts;
• and
• determine that the number of the plurality of interrupts has reached an interrupt threshold and, in response, prevent use of a link to the first PCIe device and prevent the performance of recovery operations to recover the first PCIe device from the error.

A method for handling Peripheral Component Interconnect express (PCIe) device errors in a computing device, comprising:

• receiving, by an initialization subsystem in response to an error being experienced in a first PCIe device, a plurality of interrupts that are each configured to initiate an error handling mode;
• tracking, by the initialization subsystem, a number of the plurality of interrupts;
• and
• determining, by the initialization subsystem, that the number of the plurality of interrupts has reached an interrupt threshold and, in response, preventing use of a link to the first PCIe device and preventing the performance of recovery operations to recover the first PCIe device from the error.
