config LOG_CMDS
bool "Shell commands"
depends on SHELL
depends on !LOG_MODE_MINIMAL
config LOG_TEST_CLEAR_MESSAGE_SPACE
bool "Clear message after allocation"
default y
depends on ZTEST
help
Used in testing to simplify message comparision if message contains
paddings.
config LOG_USE_VLA
bool "Using variable length arrays"
default y if !MISRA_SANE
help
Using VLA slightly decreases stack usage in some cases it may not be
supported. Note that VLA are used for arrays which size is resolved at
compile time so at runtime arrays have fixed size.
config LOG_SIMPLE_MSG_OPTIMIZE
bool "Optimize simple messages for size"
depends on !64BIT && !CBPRINTF_PACKAGE_HEADER_STORE_CREATION_FLAGS
default y
help
Dedicated code for handling simple log messages (0-2 32 bit word arguments).
Approximately, 70%-80% log messages in the application fit into that category.
Depending on the architecture code size reduction is from 0-40% (highest seen on
RISCV32) and execution time also up to 40%.
config LOG_ALWAYS_RUNTIME
bool "Always use runtime message creation (v2)"
default y if NO_OPTIMIZATIONS
default y if LOG_MODE_IMMEDIATE
default y if "$(ZEPHYR_TOOLCHAIN_VARIANT)" = "xcc"
help
If enabled, runtime method is always used for message creation. Static
creation relies on compiler being able to optimize and remove code
based on information known at compile time. Runtime only approach must
be used when optimization is disabled because some compilers
(seen on arm_cortex_m and x86) were using unrealistic amount of stack
for dead code. It is also required in immediate mode since it requires
less stack than static message creation and speed has lower priority
in that mode.
config LOG_FMT_SECTION
bool "Keep log strings in dedicated section"
help
When enabled, logs are kept in dedicated memory section. It allows
removing strings from final binary and should be used for dictionary
logging.
config LOG_FMT_SECTION_STRIP
bool "Strip log strings from binary"
depends on LOG_DICTIONARY_DB
depends on LOG_FMT_SECTION
depends on LINKER_DEVNULL_SUPPORT
depends on !LOG_ALWAYS_RUNTIME
depends on !LOG_OUTPUT

config LOG_FMT_STRING_VALIDATE
bool "Validate logging strings"
help
Logging strings cannot use %p with character pointers. They should be
casted to the pointer of another type (e.g. void *). With this feature
enabled, at compile time, the preprocessor detects strings with %p
without casting and reports an error at runtime.
config LOG_USE_TAGGED_ARGUMENTS
bool "Using tagged arguments for packaging"
depends on !PICOLIBC
select CBPRINTF_PACKAGE_SUPPORT_TAGGED_ARGUMENTS
select LOG_ALWAYS_RUNTIME
help
If enabled, packaging uses tagged arguments.
config LOG_MEM_UTILIZATION
bool "Tracking maximum memory utilization"
depends on LOG_MODE_DEFERRED
default y if LOG_CMDS
help
When enabled, maximum usage of memory used for log messages in deferred
mode is tracked. It can be used to trim LOG_BUFFER_SIZE.
config LOG_DICTIONARY_DB
bool
config LOG_DICTIONARY_DB_TARGET
bool "Only generated log dictionary database from target"
depends on LOG_DICTIONARY_DB
help
Enable this option to make generating the log dictionary database
only done by its own build target.
This removes the target from the ALL make target and the target
'log_dict_db_gen' has to be called in addition.
config LOG_MSG_APPEND_RO_STRING_LOC
bool
help
Enable this option to force log messages to always append location of
read-only string arguments in the package. This should be selected by
backends if required.
config LOG_FAILURE_REPORT_PERIOD
int "Failure report period (in milliseconds)"
default 1000
depends on LOG_MODE_DEFERRED
help
Determines how often failures are reported. Report contains number
of dropped messages. It may contain additional information depending
on the mode.
config LOG_DOMAIN_NAME
string "Domain name"
default ""
if LOG_MULTIDOMAIN
config LOG_REMOTE_DOMAIN_MAX_COUNT
int "Maximum number of link domains"
default 4
help
Number of domains that can be handled by a link
