Now that we have environment variables we can apply them to
defining errata booleans to determine behavior of report_skip
or report_xfail in tests. lib/errata.h provides handy wrappers
allowing one to do things like:
Only running dangerous tests (host crashers) when the errata
has been applied
if (!ERRATA(PPC64_TM_01))
report_skip("ERRATA_PPC64_TM_01 not set 'y', skipping...");
else
report(...);
Trigger an XFAIL vs. a FAIL, when set to 'n'
report_xfail("APIC test", !ERRATA_RELAXED(x86_APIC_01), ...);
The xfail example uses ERRATA_RELAXED to ensure we have the same
behavior as now (assuming the software under test should pass, i.e
output FAIL if it does not), when testing without the optional
environ.
