CONFIG_ACPI_HOTPLUG_MEMORY: Memory Hotplug

General informations

The Linux kernel configuration item CONFIG_ACPI_HOTPLUG_MEMORY has multiple definitions:

Memory Hotplug found in drivers/acpi/Kconfig

The configuration item CONFIG_ACPI_HOTPLUG_MEMORY:

• prompt: Memory Hotplug
• type: bool
• depends on: CONFIG_MEMORY_HOTPLUG
• defined in drivers/acpi/Kconfig
• found in Linux kernels: 3.10–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12
• modules built: acpi_memhotplug

Help text

This driver supports ACPI memory hotplug. The driver fields notifications on ACPI memory devices (PNP0C80), which represent memory ranges that may be onlined or offlined during runtime.

If your hardware and firmware do not support adding or removing memory devices at runtime, you need not enable this driver.
