CONFIG_ACPI_CUSTOM_METHOD: Allow ACPI methods to be inserted/replaced at run time

General informations

The Linux kernel configuration item CONFIG_ACPI_CUSTOM_METHOD:

• prompt: Allow ACPI methods to be inserted/replaced at run time
• type: tristate
• depends on: CONFIG_DEBUG_FS
• defined in drivers/acpi/Kconfig
• found in Linux kernels: 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8
• modules built: custom_method

Help text

This debug facility allows ACPI AML methods to be inserted and/or replaced without rebooting the system. For details refer to: Documentation/firmware-guide/acpi/method-customizing.rst.

NOTE: This option is security sensitive, because it allows arbitrary kernel memory to be written to by root (uid=0) users, allowing them to bypass certain security measures (e.g. if root is not allowed to load additional kernel modules after boot, this feature may be used to override that restriction).
