Bisecting a bug
|
||||
+++++++++++++++
|
||||
|
||||
Last updated: 28 October 2016
|
||||
|
||||
Introduction
|
||||
============
|
||||
|
||||
Always try the latest kernel from kernel.org and build from source. If you are
|
||||
not confident in doing that please report the bug to your distribution vendor
|
||||
instead of to a kernel developer.
|
||||
|
||||
Finding bugs is not always easy. Have a go though. If you can't find it don't
|
||||
give up. Report as much as you have found to the relevant maintainer. See
|
||||
MAINTAINERS for who that is for the subsystem you have worked on.
|
||||
|
||||
Before you submit a bug report read
|
||||
:ref:`Documentation/admin-guide/reporting-bugs.rst <reportingbugs>`.
|
||||
|
||||
Devices not appearing
|
||||
=====================
|
||||
|
||||
Often this is caused by udev/systemd. Check that first before blaming it
|
||||
on the kernel.
|
||||
|
||||
Finding patch that caused a bug
|
||||
===============================
|
||||
|
||||
Using the provided tools with ``git`` makes finding bugs easy provided the bug
|
||||
is reproducible.
|
||||
|
||||
Steps to do it:
|
||||
|
||||
- build the Kernel from its git source
|
||||
- start bisect with [#f1]_::
|
||||
|
||||
$ git bisect start
|
||||
|
||||
- mark the broken changeset with::
|
||||
|
||||
$ git bisect bad [commit]
|
||||
|
||||
- mark a changeset where the code is known to work with::
|
||||
|
||||
$ git bisect good [commit]
|
||||
|
||||
- rebuild the Kernel and test
|
||||
- interact with git bisect by using either::
|
||||
|
||||
$ git bisect good
|
||||
|
||||
or::
|
||||
|
||||
$ git bisect bad
|
||||
|
||||
depending if the bug happened on the changeset you're testing
|
||||
- After some interactions, git bisect will give you the changeset that
|
||||
likely caused the bug.
|
||||
|
||||
- For example, if you know that the current version is bad, and version
|
||||
4.8 is good, you could do::
|
||||
|
||||
$ git bisect start
|
||||
$ git bisect bad # Current version is bad
|
||||
$ git bisect good v4.8
|
||||
|
||||
|
||||
.. [#f1] You can, optionally, provide both good and bad arguments at git
|
||||
start::
|
||||
|
||||
git bisect start [BAD] [GOOD]
|
||||
