[Qemu-devel] [PATCH v3 0/2] acpi-test: issue errors instead of warnings when possible

[Marcel Apfelbaum]

v2->v3:
    Addressed Michael S. Tsirkin's comments:
    - got rid of a not needed if statement

v1->v2:
    Addressed Michael S. Tsirkin's comments:
    - Split the path into 2 patches
      - First patch retains both asl and aml files on failure.
      - Second one "guesses" that iasl installation is OK
        by checking that no error was returned when the
        expected tables were parsed.

[Qemu-devel] [PATCH v3 2/2] acpi-test: issue errors instead of warnings when possible

[Marcel Apfelbaum]

If the expected (offline) acpi tables loaded correctly,
it is safe to assume the iasl installation is OK and
issue an error if the actual tables differ from expected
ones.
