2 bool "Persistent store support"
7 This option enables generic access to platform level
8 persistent storage via "pstore" filesystem that can
9 be mounted as /dev/pstore. Only useful if you have
10 a platform level driver that registers with pstore to
11 provide the data, so you probably should just go say "Y"
12 (or "M") to a platform specific persistent store driver
13 (e.g. ACPI_APEI on X86) which will select this for you.
14 If you don't have a platform persistent store driver,
18 bool "Log kernel console messages"
21 When the option is enabled, pstore will log all kernel
22 messages, even if no oops or panic happened.
25 bool "Persistent function tracer"
27 depends on FUNCTION_TRACER
30 With this option kernel traces function calls into a persistent
31 ram buffer that can be decoded and dumped after reboot through
32 pstore filesystem. It can be used to determine what function
33 was last called before a reset or panic.
38 tristate "Log panic/oops to a RAM buffer"
41 depends on HAVE_MEMBLOCK
43 select REED_SOLOMON_ENC8
44 select REED_SOLOMON_DEC8
46 This enables panic and oops messages to be logged to a circular
47 buffer in RAM where it can be read back at some later point.
