Enable ways to store Linux messages in case of panics.
config PSTORE
tristate "Persistent store support"
select CRYPTO if PSTORE_COMPRESS
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.
That implicitly selects the option `EFI_VARS_PSTORE` below.
config EFI_VARS_PSTORE
tristate "Register efivars backend for pstore"
depends on EFI_VARS && PSTORE
default y
help
Say Y here to enable use efivars as a backend to pstore. This
will allow writing console messages, crash dumps, or anything
else supported by pstore to EFI variables.
Fixes: #1249

For testing purposes this has been added to A bee root build of the next linux kernel should stumble. Just remove the line when obsolete. |
