config PSTORE
	bool "Persistant 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.
pstore: new filesystem interface to platform persistent storage 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> 2010-12-28 22:25:21 +00:00			`config PSTORE`
