Test code to check if we can crash QEMU using -device. It will test all accel/machine/device combinations by default, which may take a few hours (it's more than 90k test cases). There's a "-r" option that makes it test a random sample of combinations. The scripts contains a whitelist for: 1) known error messages that make QEMU exit cleanly; 2) known QEMU crashes. This is the behavior when the script finds a failure: * Known clean (exitcode=1) errors generate DEBUG messages (hidden by default) * Unknown clean (exitcode=1) errors will generate INFO messages (visible by default) * Known crashes generate error messages, but are not fatal (unless --strict mode is used) * Unknown crashes generate fatal error messages Having an updated whitelist of known clean errors is useful to make the script less verbose and run faster when in --quick mode, but the whitelist doesn't need to be always up to date.

# 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. |
