gicv3-ipi and gicv3-active failed on Bionic Moonshot ARM64 server

[Po-Hsu Lin]

These two test will fail on a Moonshot node, with Bionic installed.

Further check with these two failed test case, they are complaining the same issue:

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1790825

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

These two tests will be skipped with QEMU 3.0.0 built from source.

[Po-Hsu Lin (cypressyew)]

On Cosmic, these test cases will be skipped:
    qemu-system-aarch64: Userspace GICv3 is not supported with KVM

So it looks like this is a qemu related issue.

[Po-Hsu Lin (cypressyew)]

For X-hwe, this gicv3-ipi is still failing but gicv3-active will pass on Moonshots node (skipped on ThunderX)

[Sean Feole (sfeole)]

So after running into bug# 1828165 I now stumbled across this one, This test is invalid, as gicv3 is only supported on arm64 hardware Thunderx and newer. the HP Moonshot cartridges are NOT to be used for this test. This needs to be blacklisted somehow, will touch base with SAM on doing so.

[Sean Feole (sfeole)]

Marking the linux bug invalid as this test is not properly targeted to run on the correct hardware
