After making some additional fixes in the arm64 kprobes support for simulating instructions that are not single stepped the systemtap testsuite made a complete run without crashing the arm64 system.
=== systemtap Summary ===
# of expected passes 2736
# of unexpected failures 689
# of unexpected successes 1
# of expected failures 312
# of unknown successes 2
# of known failures 59
# of untested testcases 408
# of unsupported tests 17
The test results have been uploaded to:
web.elastic.org/~dejazilla/viewsummary.php?summary=%3D%27%3C5464A1C7.7090000%40redhat.com%3E%27
I have not had a chance to review the test results yet. I am sure there is room for improvement in them. There are some syscall tests that need to be updated for the syscalls that the arm64 used and some of the tests fail because currently there is no uprobes support.
