Skipped test cases

LTP has over 3800 test cases. Some test cases are not suitable for testing LTS kernel on Ampere platform, e.g:

• Test cases depending on architectures other than aarch64
• Not useful for server system

These test cases are skipped in bellow ways:

1. Skip the whole test set in ltp/runtest/ directory:

$ ls /opt/ltp/runtest/
can          cpuhotplug          fcntl-locktests  fsx             io_cd             ltp-aiodio.part3      net.features   net.rpc_tests          net_stress.ipsec_icmp  net.tcp_cmds                      pty               smoketest

The skipped test set is removed from: https://github.com/AmpereComputing/ampere-lts-kernel/blob/main/tests/lkft/ltp/ltp_cmdfile:

Test set	Why skipped	Comments
io_cd
io_floppy

2. To skip individual test case:

Use https://github.com/AmpereComputing/ampere-lts-kernel/blob/main/tests/lkft/ltp/skipfile-lkft.yaml to control:

3. Skipped at ltp runtime

E.g: due to missing configurations, ltp test framework does not run the test. These test cases are counted in the LTP test result as Skipped, e.g: "Total tests 3554, Skipped 223, Failures 106"

Failed test cases

The cause for the failure is listed in: https://docs.google.com/spreadsheets/d/1kNXjuFW_OxsNXR1kxfbeIOhodwRRf8S8xdy0YSKD2l8/edit#gid=2004818483
