Recent Huawei kernel contributions (March 2025) demonstrate sophisticated WDT evolution. Engineers at Huawei have developed patches that enable the NMI watchdog (hardlockup detector) to automatically adapt to CPU frequency changes. The hardlockup_detector_perf driver, driven by PMU sample interrupts of CPU cycle events, now includes a cpufreq notifier that updates watchdog thresholds when processor speeds change. This prevents the watchdog from becoming permanently active
Reduces the need for heavy laptops and complex command-line interfaces for basic site setup. Efficiency: enabling this option provides additional security
During development, the CONFIG_WATCHDOG_NOWAYOUT option should remain disabled. This prevents the watchdog from becoming permanently active once started, allowing developers to stop it during debugging sessions. For production systems, enabling this option provides additional security, preventing malicious or buggy code from disabling the watchdog protection.
