Abstract:
In accordance with certain embodiments of the present disclosure, an information handling system is provided. The information handling system may include a plurality of processors, each processor comprising multiple cores, a memory system coupled to the plurality of processors, and a controller coupled to the plurality of processors. The controller may be configured to: receive a local system management interrupt (SMI) signal regarding an error associated with at least one of the multiple cores, determine that the received local SMI signal triggers a global SMI based on a global SMI trigger rule, cause the plurality of processors to enter a global system management mode (SMM), and log the error in a shared resource shared by the plurality of processors during the global SMM.
