For historic details see: > https://lkml.org/lkml/2014/9/2/227 What's the right way to extend your work in order to get a NMI-like watchdog hard lockup detector similar to the one on x86? I'm testing your patches on Exynos4412 and I guess in their current state they don't go quite this deep, as the only callers of trigger_all_cpu_backtrace() are sysrq, hung_task and spinlock debug code - none of which seem as fail-safe as a trigger like a pre-programmed watchdog NMI interrupt would be. Do I need to find a way to get CONFIG_FIQ available on this platform first? and/or CONFIG_HARDLOCKUP_DETECTOR?
