comment "UBI debugging options"
depends on MTD_UBI
config MTD_UBI_DEBUG
bool "UBI debugging"
depends on SYSFS
depends on MTD_UBI
select DEBUG_FS
select KALLSYMS_ALL
help
This option enables UBI debugging.
config MTD_UBI_DEBUG_MSG
bool "UBI debugging messages"
depends on MTD_UBI_DEBUG
default n
help
This option enables UBI debugging messages.
config MTD_UBI_DEBUG_PARANOID
bool "Extra self-checks"
default n
depends on MTD_UBI_DEBUG
help
This option enables extra checks in UBI code. Note this slows UBI down
significantly.
config MTD_UBI_DEBUG_DISABLE_BGT
bool "Do not enable the UBI background thread"
depends on MTD_UBI_DEBUG
default n
help
This option switches the background thread off by default. The thread
may be also be enabled/disabled via UBI sysfs.
config MTD_UBI_DEBUG_USERSPACE_IO
bool "Direct user-space write/erase support"
default n
depends on MTD_UBI_DEBUG
help
By default, users cannot directly write and erase individual
eraseblocks of dynamic volumes, and have to use update operation
instead. This option enables this capability - it is very useful for
debugging and testing.
config MTD_UBI_DEBUG_EMULATE_BITFLIPS
bool "Emulate flash bit-flips"
depends on MTD_UBI_DEBUG
default n
help
This option emulates bit-flips with probability 1/50, which in turn
causes scrubbing. Useful for debugging and stressing UBI.
config MTD_UBI_DEBUG_EMULATE_WRITE_FAILURES
bool "Emulate flash write failures"
depends on MTD_UBI_DEBUG
default n
help
This option emulates write failures with probability 1/100. Useful for
debugging and testing how UBI handlines errors.
config MTD_UBI_DEBUG_EMULATE_ERASE_FAILURES
bool "Emulate flash erase failures"
depends on MTD_UBI_DEBUG
default n
help
This option emulates erase failures with probability 1/100. Useful for
debugging and testing how UBI handlines errors.
menu "Additional UBI debugging messages"
depends on MTD_UBI_DEBUG
config MTD_UBI_DEBUG_MSG_BLD
bool "Additional UBI initialization and build messages"
default n
depends on MTD_UBI_DEBUG
help
This option enables detailed UBI initialization and device build
debugging messages.
config MTD_UBI_DEBUG_MSG_EBA
bool "Eraseblock association unit messages"
default n
depends on MTD_UBI_DEBUG
help
This option enables debugging messages from the UBI eraseblock
association unit.
config MTD_UBI_DEBUG_MSG_WL
bool "Wear-leveling unit messages"
default n
depends on MTD_UBI_DEBUG
help
This option enables debugging messages from the UBI wear-leveling
unit.
config MTD_UBI_DEBUG_MSG_IO
bool "Input/output unit messages"
default n
depends on MTD_UBI_DEBUG
help
This option enables debugging messages from the UBI input/output unit.
