The Linux kernel configuration item CONFIG_FRAME_POINTER
has multiple definitions:
lib/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
( CONFIG_DEBUG_KERNEL && ( CONFIG_M68K || CONFIG_UML || CONFIG_SUPERH ) || CONFIG_ARCH_WANT_FRAME_POINTERS ) && (( CONFIG_DEBUG_INFO && CONFIG_UML ) || CONFIG_ARCH_WANT_FRAME_POINTERS )
If you say Y here the resulting kernel image will be slightly larger and slower, but it gives very useful debugging information in case of kernel bugs. (precise oopses/stacktraces/warnings)
arch/x86/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
! CONFIG_UNWINDER_ORC && ! CONFIG_UNWINDER_GUESS
(none)
arch/sparc/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
CONFIG_MCOUNT
(none)
arch/hexagon/Kconfig
The configuration item CONFIG_FRAME_POINTER:
(none)
(none)
arch/arm/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
(none)
(none)
arch/m32r/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
(none)
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/arm64/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
(none)
(none)
arch/xtensa/Kconfig
The configuration item CONFIG_FRAME_POINTER:
(none)
(none)
arch/sparc64/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
CONFIG_MCOUNT
(none)
arch/sh64/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
CONFIG_KGDB
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/arm26/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
(none)
If you say N here, the resulting kernel will be slightly smaller and faster. However, when a problem occurs with the kernel, the information that is reported is severely limited. Most people should say Y here.
arch/sh/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
CONFIG_KGDB
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/cris/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
(none)
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/frv/Kconfig
The configuration item CONFIG_FRAME_POINTER:
CONFIG_DEBUG_KERNEL
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/um/Kconfig.debug
The configuration item CONFIG_FRAME_POINTER:
CONFIG_DEBUG_INFO
(none)
arch/ppc64/Kconfig
The configuration item CONFIG_FRAME_POINTER:
(none)
(none)
arch/m32r/Kconfig
The configuration item CONFIG_FRAME_POINTER:
(none)
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/x86_64/Kconfig
The configuration item CONFIG_FRAME_POINTER:
(none)
Compile the kernel with frame pointers. This may help for some debugging with external debuggers. Note the standard oops backtracer doesn't make use of this and the x86-64 kernel doesn't ensure an consistent frame pointer through inline assembly (semaphores etc.) Normally you should say N.
arch/sh64/Kconfig
The configuration item CONFIG_FRAME_POINTER:
CONFIG_KGDB
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/sh/Kconfig
The configuration item CONFIG_FRAME_POINTER:
CONFIG_KGDB
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/parisc/Kconfig
The configuration item CONFIG_FRAME_POINTER:
(none)
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/m68knommu/Kconfig
The configuration item CONFIG_FRAME_POINTER:
(none)
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
arch/i386/Kconfig
The configuration item CONFIG_FRAME_POINTER:
(none)
If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers.
