CONFIG_PAGE_SIZE_64KB: 64KiB pages

General informations

The Linux kernel configuration item CONFIG_PAGE_SIZE_64KB has multiple definitions:

64KiB pages found in arch/Kconfig

The configuration item CONFIG_PAGE_SIZE_64KB:

• prompt: 64KiB pages
• type: bool
• depends on: CONFIG_HAVE_PAGE_SIZE_64KB
• defined in arch/Kconfig
• found in Linux kernels: 6.9–6.14, 6.15-rc+HEAD

Help text

Using 64KiB page size will result in slightly higher performance kernel at the price of much higher memory consumption compared to 4KiB or 16KiB pages. This is not suitable for general-purpose workloads but the better performance may be worth the cost for certain types of supercomputing or database applications that work mostly with large in-memory data rather than small files.

64kB found in arch/sh/mm/Kconfig

The configuration item CONFIG_PAGE_SIZE_64KB:

• prompt: 64kB
• type: bool
• depends on: ! CONFIG_MMU || CONFIG_CPU_SH4
• defined in arch/sh/mm/Kconfig
• found in Linux kernels: 2.6.20–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8

Help text

This enables support for 64kB pages, possible on all SH-4 CPUs and later.

64kB found in arch/mips/Kconfig

The configuration item CONFIG_PAGE_SIZE_64KB:

• prompt: 64kB
• type: bool
• depends on: ! CONFIG_CPU_R3000
• defined in arch/mips/Kconfig
• found in Linux kernels: 2.6.4–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8

Help text

Using 64kB page size will result in higher performance kernel at the price of higher memory consumption. This option is available on all non-R3000 family processor. Not that at the time of this writing this option is still high experimental.
