[ros-diffs] [ros-arm-bringup] 44878: NMI Support Patch 13: [NMIDEBUG]: Add new NMI Debug driver. It registers an NMI callback on startup. The callback does nothing useful at the moment, but you can enhance it to add all sorts of debugging information that would otherwise be unavailable in situations such as an interrupt storm, IRQL hang, etc. When you send an NMI, such as by using QEMU, you should see the driver print a string.
