$ sudo ./tm-unavailable
Checking if FP/VEC registers are sane after a FP unavailable exception...
Illegal instruction
For Power8 it's OK:
For P9 on Cosmic, this test will be skipped:

== Justification ==
The tm-unavailable test in powerpc from ubuntu_kernel_selftests will fail on Bionic PowerPC:
$ sudo ./tm-unavailable
Checking if FP/VEC registers are sane after a FP unavailable exception...
Illegal instruction
This is because the Hardware Transactional Memory (HTM) is not supported on the revision of the processor in our PowerPC boxes.
== Fix ==
b395e55b (selftests/powerpc: Skip tm-unavailable if TM is not enabled)
With a prerequisite to make it a clean cherry-pick:
5783ee6e (selftests/powerpc: Check for pthread errors in tm-unavailable)
An extra check for this test:
SKIP_IF(!have_htm())
Will be added to ensure we have HTM support before start testing.
This patchset has already landed in Cosmic and newer, and can be cherry-picked for Bionic.
For Xenial, we don't have this test in our tree.
== Test ==
Patch verified on a Bionic P9 system, the test will be marked as passed (skipped) with these two patches applied.
== Regression potential ==
None.
This patch is just for the kernel testing tool.
