Detailed Description

Function Documentation

k_obj_core_stats_deregister()

int k_obj_core_stats_deregister

(

struct k_obj_core *

obj_core

)

#include <zephyr/kernel/obj_core.h>

Deregister kernel object from gathering statistics.

Deregistering a kernel object core from gathering statistics prevents it from gathering any more statistics. It is expected to be invoked at the end of a kernel object's life cycle.

Parameters

obj_core

Pointer to kernel object core

Return values

0	on success
-errno	on failure

k_obj_core_stats_disable()

int k_obj_core_stats_disable

(

struct k_obj_core *

obj_core

)

#include <zephyr/kernel/obj_core.h>

Stop gathering the stats associated with the kernel object.

This function temporarily stops the gathering of statistics associated with the kernel object core specified by obj_core. The gathering of statistics can be resumed by invoking :c:func :k_obj_core_stats_enable.

Parameters

obj_core

Pointer to kernel object core

Return values

0	on success
-errno	on failure

k_obj_core_stats_enable()

int k_obj_core_stats_enable

(

struct k_obj_core *

obj_core

)

#include <zephyr/kernel/obj_core.h>

Reset the stats associated with the kernel object.

This function resumes the gathering of statistics associated with the kernel object core specified by obj_core.

Parameters

obj_core

Pointer to kernel object core

Return values

0	on success
-errno	on failure

k_obj_core_stats_query()

int k_obj_core_stats_query	(	struct k_obj_core *	obj_core,
		void *	stats,
		size_t	stats_len )

#include <zephyr/kernel/obj_core.h>

Retrieve the statistics associated with the kernel object.

This function copies the statistics associated with the kernel object core specified by obj_core into the buffer stats. Unlike the raw statistics this may report calculated values such as averages. Note that the size of the buffer (stats_len) must match the size specified by the kernel object type's statistics descriptor.

Parameters

obj_core	Pointer to kernel object core
stats	Pointer to memory buffer into which to copy the queried stats
stats_len	Length of the memory buffer

Return values

0	on success
-errno	on failure

k_obj_core_stats_raw()

int k_obj_core_stats_raw	(	struct k_obj_core *	obj_core,
		void *	stats,
		size_t	stats_len )

#include <zephyr/kernel/obj_core.h>

Retrieve the raw statistics associated with the kernel object.

This function copies the raw statistics associated with the kernel object core specified by obj_core into the buffer stats. Note that the size of the buffer (stats_len) must match the size specified by the kernel object type's statistics descriptor.

Parameters

obj_core	Pointer to kernel object core
stats	Pointer to memory buffer into which to copy raw stats
stats_len	Length of the memory buffer

Return values

0	on success
-errno	on failure

k_obj_core_stats_register()

int k_obj_core_stats_register	(	struct k_obj_core *	obj_core,
		void *	stats,
		size_t	stats_len )

#include <zephyr/kernel/obj_core.h>

Register kernel object for gathering statistics.

Before a kernel object can gather statistics, it must be registered to do so. Registering will also automatically enable the kernel object to gather its statistics.

Parameters

obj_core	Pointer to kernel object core
stats	Pointer to raw kernel statistics
stats_len	Size of raw kernel statistics buffer

Return values

0	on success
-errno	on failure

k_obj_core_stats_reset()

int k_obj_core_stats_reset

(

struct k_obj_core *

obj_core

)

#include <zephyr/kernel/obj_core.h>

Reset the stats associated with the kernel object.

This function resets the statistics associated with the kernel object core specified by obj_core.

Parameters

obj_core

Pointer to kernel object core

Return values

0	on success
-errno	on failure
