Error Detection and Correction (EDAC) is critical for ensuring data integrity and system reliability, particularly in modern high-performance computing architectures. ARM’s Generic Interrupt Controller is widely used in multi-core processors design, where fault tolerance is essential for maintaining system stability. With the rising risk of transient and permanent faults due to hardware aging, radiation effects, and environmental interference, integrating EDAC mechanisms into interrupt controller is essential for preventing data corruption and unexpected system failures.

This work presents the first implementation of EDAC for ARM GIC-600 interrupt controller in Linux kernel, extending EDAC subsystem with new patches and drivers to integrate ARM’s error-reporting capabilities. The talk explores the necessity of EDAC in mitigating errors in interrupt controller and includes sample code snippets demonstrating how to extend the Linux EDAC framework to support error logging and correction.

Furthermore, we present performance benchmarks and case studies evaluating the effectiveness of EDAC in interrupt controller, highlighting trade-offs between error resilience and system overhead.
