44 # Purposes of the following whitelist:
45 # * Avoiding verbose log messages when we find known non-fatal
47 # * Avoiding fatal errors when we find known crashes
48 # * Skipping machines/devices that are known not to work out of
49 # the box, when running in --quick mode
51 # Keeping the whitelist updated is desirable, but not required,
52 # because unexpected cases where QEMU exits with exitcode=1 will
53 # just trigger a INFO message.
55 # Valid whitelist entry keys:
56 # * accel: regexp, full match only
57 # * machine: regexp, full match only
58 # * device: regexp, full match only
59 # * log: regexp, partial match allowed
60 # * exitcode: if not present, defaults to 1. If None, matches any exitcode
61 # * warn: if True, matching failures will be logged as warnings
62 # * expected: if True, QEMU is expected to always fail every time
63 # when testing the corresponding test case
64 # * loglevel: log level of log output when there's a match.
