Some platforms have a small amount of non-volatile storage that can be used to store information useful to diagnose the cause of a system crash. This is the generic part of a file system interface that presents information from the crash as a series of files in /dev/pstore. Once the information has been seen, the underlying storage is freed by deleting the files. Signed-off-by: Tony Luck <tony.luck@intel.com>

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.
