[Qemu-devel] [PATCH v2 0/3] script for crash-testing -device
Posted by Eduardo Habkost 8 years, 9 months ago 
Changes v1 -> v2:
* Use a simpler method to query QEMU exit code in qemu.py
* Use only qemu.py module, instead of qtest.py
* New whitelist entries:
  * "could not find stage1 bootloader"
  * Segfaults when using devices: a15mpcore_priv, sb16, cs4231a, arm-gicv3
* Format "success" line using formatTestCase(), and using DEBUG
  loglevel
* Reword "test case:" line with "running test case:", for clarity
* Fix "pc-.*" whitelist to include "q35" too
* Add --devtype option to test only a specific device type
* Send all log messages to stdout instead of stderr
* Avoid printing "obsolete whitelist entry?" messages if we know
  we are not testing every single accel/machine/device
  combination
* --quick mode, to skip cases where failures are always expected,
  and to print a warning in case we don't get an expected failure
* Use qemu.QEMUMachine instead of qtest.QEMUQtestMachine, as we don't
  use any of the QEMUQtestMachine features
* Fix handling of multiple '-t' options
* Simplify code that generate random sample of test cases

This series adds scripts/device-crashtest.py, that can be used to
crash-test -device with multiple machine/accel/device
combinations.

The script found a few crashes on some machines/devices. A dump
of existing cases can be seen here:
  https://gist.github.com/ehabkost/503b0af0375f0d98d3e84017e8ca54eb

The script contains a whitelist that can also be useful as
documentation of existing ways -device can fail or crash.

Note that the script takes a few hours to run on the default mode
(testing all accel/machine/device combinations), but the "-r N"
option can be used to make it only test N random samples.

Example script output:
