14 // e32test\device\t_tldd.cpp |
|
15 // Overview: |
|
16 // Test device driver loading and unloading and |
|
17 // the RBusLogicalChannel hook functionality. |
|
18 // API Information: |
|
19 // RBusLogicalChannel, DLogicalChannel, Kern::InstallLogicalDevice. |
|
20 // Details: |
|
21 // - Test loading the test logical device driver "D_LDD" and creating a logical |
|
22 // channel. |
|
23 // - Test initialisation of LDD data and bss sections |
|
24 // - Test passing data to driver and back, and storing it in data/bss/heap |
|
25 // areas |
|
26 // - Test contructors were called for driver global data |
|
27 // - Test functionality of Kern::InstallLogicalDevice by asking the test LDD |
|
28 // to create a second device. Check this device works, and check it goes |
|
29 // away when freed. |
|
30 // - Check the return value as KErrInUse when the LDD close method is called |
|
31 // before closing the handle. |
|
32 // - Close the handle and unload the device, verify success. |
|
33 // - Check that no memory is leaked on the kernel heap |
|
34 // - Load the logical device driver again and verify that the global variables |
|
35 // and bss have been reinitialized. |
|
36 // - Close the handle and unload the device, verify success. |
|
37 // - Test User::LoadLogicalDevice and User::FreeLogicalDevice APIs, including |
|
38 // free whilst in use and load whilst already loaded |
|
39 // - On hardware, repeat all tests with the "D_LDD_RAM" device driver. |
|
40 // - Check the return value is KErrNotSupported when trying to load invalid |
|
41 // logical device driver. |
|
42 // Platforms/Drives/Compatibility: |
|
43 // All. |
