Revision 5ca1b0dd016701f67994414a2af50dec6efcf103 authored by Brian Norris on 17 March 2015, 19:30:32 UTC, committed by Rob Herring on 19 March 2015, 13:39:44 UTC
There were regressions seen with commit 106937e8ccdc ("of: fix handling of '/' in options for of_find_node_by_path()"), where we couldn't handle extra '/' before the ':'. Let's test for this now. Confirmed that this test fails without the previous patch and passes when patched. All other tests pass.

Kconfig
config PSTORE
bool "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".
