CONFIG_UNWINDER_FRAME_POINTER: Frame pointer unwinder

General informations

The Linux kernel configuration item CONFIG_UNWINDER_FRAME_POINTER has multiple definitions:

Frame pointer unwinder found in arch/x86/Kconfig.debug

The configuration item CONFIG_UNWINDER_FRAME_POINTER:

• prompt: Frame pointer unwinder
• type: bool
• depends on: (none)
• defined in arch/x86/Kconfig.debug
• found in Linux kernels: 4.15–4.20, 5.0–5.19, 6.0–6.12

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%.
