CONFIG_3_LEVEL_PGTABLES: Three-level pagetables

General informations

The Linux kernel configuration item CONFIG_3_LEVEL_PGTABLES has multiple definitions:

Three-level pagetables found in arch/x86/um/Kconfig

The configuration item CONFIG_3_LEVEL_PGTABLES:

• prompt: Three-level pagetables
• type: bool
• depends on: ! CONFIG_64BIT
• defined in arch/x86/um/Kconfig
• found in Linux kernels: 3.9–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD

Three-level pagetables will let UML have more than 4G of physical memory. All the memory that can't be mapped directly will be treated as high memory.

However, this it experimental on 32-bit architectures, so if unsure say N (on x86-64 it's automatically enabled, instead, as it's safe there).

Three-level pagetables (EXPERIMENTAL) found in arch/x86/um/Kconfig

The configuration item CONFIG_3_LEVEL_PGTABLES:

• prompt: Three-level pagetables (EXPERIMENTAL)
• type: bool
• depends on: (! CONFIG_64BIT ) && ( CONFIG_EXPERIMENTAL )
• defined in arch/x86/um/Kconfig
• found in Linux kernels: 3.2–3.8
