General informations

The Linux kernel configuration item CONFIG_DEBUG_VM_PGTABLE:

• prompt: Debug arch page table for semantics compliance
• type: bool
• depends on: ( CONFIG_MMU ) && ( CONFIG_ARCH_HAS_DEBUG_VM_PGTABLE ) && ( CONFIG_DEBUG_VM )
• defined in lib/Kconfig.debug
• found in Linux kernels: 5.8–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

This option provides a debug method which can be used to test architecture page table helper functions on various platforms in verifying if they comply with expected generic MM semantics. This will help architecture code in making sure that any changes or new additions of these helpers still conform to expected semantics of the generic MM. Platforms will have to opt in for this through ARCH_HAS_DEBUG_VM_PGTABLE.

If unsure, say N.
