Here's a KVM-unit-test to check the persistency of SPRs during migration.
First patch adds a helper script for doing migration tests in the
kvm-unit-test framework, and the second patch contains the SPR tester.
v2:
- Addressed review feedback from v1
- Now using cpu_relax() instead of asm volatile ("nop")
Thomas Huth (2):
Add the possibility to do simple migration tests
