[PATCH v5] arm64: Enable perf events based hard lockup detector

2021-01-15 Thread Sumit Garg
With the recent feature added to enable perf events to use pseudo NMIs as interrupts on platforms which support GICv3 or later, its now been possible to enable hard lockup detector (or NMI watchdog) on arm64 platforms. So enable corresponding support. One thing to note here is that normally
