   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.

  17         depends on PSTORE
  18         depends on HAS_IOMEM
  19         depends on HAVE_MEMBLOCK
  20         select REED_SOLOMON
  21         select REED_SOLOMON_ENC8
  22         select REED_SOLOMON_DEC8
  23         help
  24           This enables panic and oops messages to be logged to a circular
  25           buffer in RAM where it can be read back at some later point.
