    tools/testing/nvdimm: unit test acpi_nfit_ctl() · a7de92da
    Dan Williams authored
    A recent flurry of bug discoveries in the nfit driver's DSM marshalling
    routine has highlighted the fact that we do not have unit test coverage
    for this routine. Add a self-test of acpi_nfit_ctl() routine before
    probing the "nfit_test.0" device. This mocks stimulus to acpi_nfit_ctl()
    and if any of the tests fail "nfit_test.0" will be unavailable causing
    the rest of the tests to not run / fail.
    
    This unit test will also be a place to land reproductions of quirky BIOS
    behavior discovered in the field and ensure the kernel does not regress
    against implementations it has seen in practice.
