CONFIG_FRAME_POINTER_UNWINDER: Frame pointer unwinder

General informations

The Linux kernel configuration item CONFIG_FRAME_POINTER_UNWINDER:

• prompt: Frame pointer unwinder
• type: bool
• depends on: (none)
• defined in arch/x86/Kconfig.debug
• found in Linux kernels: 4.14

Help text

This option enables the frame pointer unwinder for unwinding kernel stack traces.

The unwinder itself is fast and it uses less RAM than the ORC unwinder, but the kernel text size will grow by ~3% and the kernel's overall performance will degrade by roughly 5-10%.

This option is recommended if you want to use the livepatch consistency model, as this is currently the only way to get a reliable stack trace (HAVE_RELIABLE_STACKTRACE).
