[redhat] New configs in lib/Kconfig.debug

CKI ARK Botrequested to merge
configs/2020-12-15/lib/Kconfig.debug into os-build

Hi,

As part of the ongoing rebase effort, the following configuration options need to be reviewed.

As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy.

If the value for a file that is added should be changed, please reply with a better option.

CONFIG_HARDLOCKUP_DETECTOR:

Say Y here to enable the kernel to act as a watchdog to detect hard lockups.

Hardlockups are bugs that cause the CPU to loop in kernel mode for more than 10 seconds, without letting other interrupts have a chance to run. The current stack trace is displayed upon detection and the system will stay locked up.

Symbol: HARDLOCKUP_DETECTOR [=n] Type : bool Defined at lib/Kconfig.debug:1000 Prompt: Detect Hard Lockups Depends on: DEBUG_KERNEL [=y] && !S390 && (HAVE_HARDLOCKUP_DETECTOR_PERF [=y] || HAVE_HARDLOCKUP_DETECTOR_ARCH [=n]) Location: -> Kernel hacking -> Debug Oops, Lockups and Hangs Selects: LOCKUP_DETECTOR [=y] && HARDLOCKUP_DETECTOR_PERF [=n] && HARDLOCKUP_DETECTOR_ARCH
