CONFIG_PSTORE: Persistent store support

General informations

The Linux kernel configuration item CONFIG_PSTORE has multiple definitions:

Persistent store support found in fs/pstore/Kconfig

The configuration item CONFIG_PSTORE:

• prompt: Persistent store support
• type: tristate
• depends on: (none)
• defined in fs/pstore/Kconfig
• found in Linux kernels: 4.4–4.20, 5.0–5.19, 6.0–6.12
• modules built: pstore

Help text

This option enables generic access to platform level persistent storage via "pstore" filesystem that can be mounted as /dev/pstore. Only useful if you have a platform level driver that registers with pstore to provide the data, so you probably should just go say "Y" (or "M") to a platform specific persistent store driver (e.g. ACPI_APEI on X86) which will select this for you. If you don't have a platform persistent store driver, say N.
