HELPER_STACK_SIZE

#define HELPER_STACK_SIZE   500

IDLE_EVENT_STATS_PRECISION

#define IDLE_EVENT_STATS_PRECISION   1

TEST_WITHIN_X_PERCENT

#define TEST_WITHIN_X_PERCENT	(		val1,
			val2,
			pcnt
	)

Value:

        ((((val1) * 100) < ((val2) * (100 + (pcnt)))) &&              \
         (((val1) * 100) > ((val2) * (100 - (pcnt))))) ? true : false

Verify va1 and val2 are within pcnt % of each other.

Function Documentation

busy_loop()

void busy_loop

(

uint32_t

ticks

)

Busy wait for specified number of ticks.

helper1()

void helper1	(	void *	p1,
		void *	p2,
		void *	p3
	)

Helper thread to test_thread_runtime_stats_get()

ZTEST() [1/4]

ZTEST	(	usage_api	,
		test_all_stats_usage
	)

Test the k_threads_runtime_stats_all_get() API.

1. Create a helper thread.
2. Busy loop for 2 ticks.
   • Idle time should not increase.
3. Sleep for two ticks. Helper executes and busy loops.
   • Idle time should not increase
4. Kill helper thread, and sleep for 2 ticks
   • Idle time should increase
5. Busy loop for 3 ticks
   • Idle time should not increase
   • current, peak and average cycles should be different

ZTEST() [2/4]

ZTEST	(	usage_api	,
		test_sys_stats_enable_disable
	)

ZTEST() [3/4]

ZTEST	(	usage_api	,
		test_thread_stats_enable_disable
	)

ZTEST() [4/4]

ZTEST	(	usage_api	,
		test_thread_stats_usage
	)

Test the k_thread_runtime_stats_get() API.

This routine tests the k_thread_runtime_stats_get() routine. It verifies that the contents of the fields guarded by CONFIG_SCHED_THREAD_USAGE are correct.
