Function Documentation

test_k_mem_map_exhaustion()

void test_k_mem_map_exhaustion

(

void

)

test_k_mem_map_guard_after()

void test_k_mem_map_guard_after

(

void

)

Test that the "after" guard page is in place for k_mem_map().

test_k_mem_map_guard_before()

void test_k_mem_map_guard_before

(

void

)

Test that the "before" guard page is in place for k_mem_map().

test_k_mem_map_unmap()

void test_k_mem_map_unmap

(

void

)

Basic k_mem_map() and k_mem_unmap() functionality

Does not exercise K_MEM_MAP_* control flags, just default behavior

test_main()

void test_main

(

void

)

test case main entry

test_z_phys_map_exec()

void test_z_phys_map_exec

(

void

)

Show that mapping with/without K_MEM_PERM_EXEC works as expected

test_z_phys_map_rw()

void test_z_phys_map_rw

(

void

)

Show that mapping an irregular size buffer works and RW flag is respected

test_z_phys_map_side_effect()

void test_z_phys_map_side_effect

(

void

)

Show that memory mapping doesn't have unintended side effects

test_z_phys_unmap()

void test_z_phys_unmap

(

void

)

Test that z_phys_unmap() unmaps the memory and it is no longer accessible afterwards.
