test_generic_object()

void test_generic_object

(

)

Test to verify object permission.

• The kernel must be able to associate kernel object memory addresses with whether the calling thread has access to that object, the object is of the expected type, and the object is of the expected init state.
• Test support freeing kernel objects allocated at runtime manually.

(

)

Test requestor thread will implicitly be assigned permission on the dynamically allocated object.

• Create kernel object semaphore, dynamically allocate it from the calling thread's resource pool.
• Check that object's address is in bounds of that memory pool.
• Then check the requestor thread will implicitly be assigned permission on the allocated object by using semaphore API k_sem_init()

test_no_ref_dyn_kobj_release_mem()

void test_no_ref_dyn_kobj_release_mem

(

void

)

Test dynamically allocated kernel object release memory.

Dynamically allocated kernel objects whose access is controlled by the permission system will use object permission as a reference count. If no threads have access to an object, the object's memory released.
