Verify that IFS sysfs entries are created after loading the IFS module 2. Check if loading an invalid IFS test image fails and loading a valid one succeeds 3. Perform IFS scan test on each CPU using all the available image files 4. Perform IFS scan with first test image file on a random CPU for 3 rounds 5. Perform IFS ARRAY BIST(Board Integrated System Test) test on each CPU 6. Perform IFS ARRAY BIST test on a random CPU for 3 rounds These are not exhaustive, but some minimal test runs to check various parts of the driver. Some negative tests are also included.
