[Qemu-devel] [PATCH 0/3] script for crash-testing -device |
Date: |
Wed, 22 Mar 2017 13:00:49 -0300 |
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:
