1config PSTORE 2 bool "Persistent store support" 3 default n 4 help 5 This option enables generic access to platform level 6 persistent storage via "pstore" filesystem that can 7 be mounted as /dev/pstore. Only useful if you have 8 a platform level driver that registers with pstore to 9 provide the data, so you probably should just go say "Y" 10 (or "M") to a platform specific persistent store driver 11 (e.g. ACPI_APEI on X86) which will select this for you. 12 If you don't have a platform persistent store driver, 13 say N. 14 15config PSTORE_RAM 16 tristate "Log panic/oops to a RAM buffer" 17 depends on PSTORE 18 depends on HAS_IOMEM 19 depends on HAVE_MEMBLOCK 20 select REED_SOLOMON 21 select REED_SOLOMON_ENC8 22 select REED_SOLOMON_DEC8 23 help 24 This enables panic and oops messages to be logged to a circular 25 buffer in RAM where it can be read back at some later point. 26 27 Note that for historical reasons, the module will be named 28 "ramoops.ko". 29 30 For more information, see Documentation/ramoops.txt. 31
