config PSTORE
bool "Persistent store support"
default n
help
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.
config PSTORE_RAM
tristate "Log panic/oops to a RAM buffer"
depends on PSTORE
depends on HAS_IOMEM
depends on HAVE_MEMBLOCK
select REED_SOLOMON
select REED_SOLOMON_ENC8
select REED_SOLOMON_DEC8
help
This enables panic and oops messages to be logged to a circular
buffer in RAM where it can be read back at some later point.
Note that for historical reasons, the module will be named
"ramoops.ko".
For more information, see Documentation/ramoops.txt.
