[kvm-unit-tests PATCH v4 0/2] powerpc: Test SPR persistency during migration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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")

Thomas Huth (2):
  Add the possibility to do simple migration tests
  powerpc: Add Special Purpose Register persistency test
