CONFIG_X86_PTDUMP: Export kernel pagetable layout to userspace via debugfs

General informations

The Linux kernel configuration item CONFIG_X86_PTDUMP has multiple definitions:

Export kernel pagetable layout to userspace via debugfs found in arch/x86/Kconfig.debug

The configuration item CONFIG_X86_PTDUMP:

• prompt: Export kernel pagetable layout to userspace via debugfs
• type: tristate
• depends on: CONFIG_DEBUG_KERNEL
• defined in arch/x86/Kconfig.debug
• found in Linux kernels: 4.5–4.20, 5.0–5.5
• modules built: debug_pagetables

Help text

Say Y here if you want to show the kernel pagetable layout in a debugfs file. This information is only useful for kernel developers who are working in architecture specific areas of the kernel. It is probably not a good idea to enable this feature in a production kernel. If in doubt, say "N"
