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