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.
v4:
- Fix the error paths in run_migration() - use "exit 2" instead of "exit 1"
to avoid trouble with the return code magic in the powerpc/run script
and make sure to terminate the two QEMU instances in case of migration
failure.
v3:
- Migration shell script code has been moved to a helper function in
arch-run.bash, so that this now also works with the standalone tests.
- Introduced the helper function migration_cmd there, too, so that other
architectures can use this, too.
- Use "$@" instead of $* when calling QEMU.
v2:
- Addressed review feedback from v1
- Now using cpu_relax() instead of asm volatile ("nop")
