config PSTORE tristate "Persistent store support" default n select ZLIB_DEFLATE select ZLIB_INFLATE 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. config PSTORE_CONSOLE bool "Log kernel console messages" depends on PSTORE help When the option is enabled, pstore will log all kernel messages, even if no oops or panic happened. config PSTORE_PMSG bool "Log user space messages" depends on PSTORE help When the option is enabled, pstore will export a character interface /dev/pmsg0 to log user space messages. On reboot data can be retrieved from /sys/fs/pstore/pmsg-ramoops-[ID]. If unsure, say N. config PSTORE_FTRACE bool "Persistent function tracer" depends on PSTORE depends on FUNCTION_TRACER depends on DEBUG_FS help With this option kernel traces function calls into a persistent ram buffer that can be decoded and dumped after reboot through pstore filesystem. It can be used to determine what function was last called before a reset or panic. If unsure, say N. config PSTORE_RAM tristate "Log panic/oops to a RAM buffer" depends on PSTORE depends on HAS_IOMEM depends on HAVE_MEMBLOCK select REED_SOLOMON select REED_SOLOMON_ENC8 select REED_SOLOMON_DEC8 help 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. Note that for historical reasons, the module will be named "ramoops.ko". For more information, see Documentation/ramoops.txt.
