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.

When the option is enabled, pstore will log all kernel

messages, even if no oops or panic happened.

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.
