   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.

  15 config PSTORE_CONSOLE
  16         bool "Log kernel console messages"
  17         depends on PSTORE
  18         help
  19           When the option is enabled, pstore will log all kernel
  20           messages, even if no oops or panic happened.
  21
  22 config PSTORE_RAM
  23         tristate "Log panic/oops to a RAM buffer"
  24         depends on PSTORE
  25         depends on HAS_IOMEM
  26         depends on HAVE_MEMBLOCK
  27         select REED_SOLOMON
  28         select REED_SOLOMON_ENC8
  29         select REED_SOLOMON_DEC8
  30         help
  31           This enables panic and oops messages to be logged to a circular
  32           buffer in RAM where it can be read back at some later point.

  34           Note that for historical reasons, the module will be named
  35           "ramoops.ko".
