General informations

The Linux kernel configuration item CONFIG_SINGLE_MEMORY_CHUNK has multiple definitions:

Use one physical chunk of memory only found in arch/m68k/Kconfig.cpu

The configuration item CONFIG_SINGLE_MEMORY_CHUNK:

• prompt: Use one physical chunk of memory only
• type: bool
• depends on: ( CONFIG_ADVANCED && ! CONFIG_SUN3 ) && ( CONFIG_MMU ) && ( CONFIG_SUN3 || CONFIG_MMU_COLDFIRE )
• defined in arch/m68k/Kconfig.cpu
• found in Linux kernels: 3.2–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD

Ignore all but the first contiguous chunk of physical memory for VM purposes. This will save a few bytes kernel size and may speed up some operations. When this option os set to N, you may want to lower "Maximum zone order" to save memory that could be wasted for unused memory map. Say N if not sure.
