  1. config PSTORE
  2. bool "Persistent store support"
  3. default n
  4. help
  5. This option enables generic access to platform level
  6. persistent storage via "pstore" filesystem that can
  7. be mounted as /dev/pstore. Only useful if you have
  8. a platform level driver that registers with pstore to
  9. provide the data, so you probably should just go say "Y"
  10. (or "M") to a platform specific persistent store driver
  11. (e.g. ACPI_APEI on X86) which will select this for you.
  12. If you don't have a platform persistent store driver,
  13. say N.
  14. config PSTORE_RAM
  15. tristate "Log panic/oops to a RAM buffer"
  16. depends on PSTORE
  17. depends on HAS_IOMEM
  18. depends on HAVE_MEMBLOCK
  19. select REED_SOLOMON
  20. select REED_SOLOMON_ENC8
  21. select REED_SOLOMON_DEC8
  22. help
  23. This enables panic and oops messages to be logged to a circular
  24. buffer in RAM where it can be read back at some later point.
  25. Note that for historical reasons, the module will be named
  26. "ramoops.ko".
