The issue doesn't seem to be with this patch. But with the specific setup of the machine, it is a RHEL7 based setup, where it seems the kernel doesn't setup the vector capability, but the machine does have the vx facility. That seems to cause our tests prereq to think it can run the vector instructions, but when the actual vector* tests run the instructions fail because the kernel hasn't enabled them. So it seems we need to make tests/s390x_features s390x-vx smarter. Cheers, Mark |
