|
||||
|
||||
KUnit isn't working, what should I do?
|
||||
======================================
|
||||
|
||||
Unfortunately, there are a number of things which can break, but here are some
|
||||
things to try.
|
||||
|
||||
1. Try running ``./tools/testing/kunit/kunit.py run`` with the ``--raw_output``
|
||||
parameter. This might show details or error messages hidden by the kunit_tool
|
||||
parser.
|
||||
2. Instead of running ``kunit.py run``, try running ``kunit.py config``,
|
||||
``kunit.py build``, and ``kunit.py exec`` independently. This can help track
|
||||
down where an issue is occurring. (If you think the parser is at fault, you
|
||||
can run it manually against stdin or a file with ``kunit.py parse``.)
|
||||
3. Running the UML kernel directly can often reveal issues or error messages
|
||||
kunit_tool ignores. This should be as simple as running ``./vmlinux`` after
|
||||
building the UML kernel (e.g., by using ``kunit.py build``). Note that UML
|
||||
has some unusual requirements (such as the host having a tmpfs filesystem
|
||||
mounted), and has had issues in the past when built statically and the host
|
||||
has KASLR enabled. (On older host kernels, you may need to run ``setarch
|
||||
`uname -m` -R ./vmlinux`` to disable KASLR.)
|
||||
4. Make sure the kernel .config has ``CONFIG_KUNIT=y`` and at least one test
|
||||
(e.g. ``CONFIG_KUNIT_EXAMPLE_TEST=y``). kunit_tool will keep its .config
|
||||
around, so you can see what config was used after running ``kunit.py run``.
|
||||
It also preserves any config changes you might make, so you can
|
||||
enable/disable things with ``make ARCH=um menuconfig`` or similar, and then
|
||||
re-run kunit_tool.
|
||||
5. Try to run ``make ARCH=um defconfig`` before running ``kunit.py run``. This
|
||||
may help clean up any residual config items which could be causing problems.
|
||||
6. Finally, try running KUnit outside UML. KUnit and KUnit tests can run be
|
||||
built into any kernel, or can be built as a module and loaded at runtime.
|
||||
Doing so should allow you to determine if UML is causing the issue you're
|
||||
seeing. When tests are built-in, they will execute when the kernel boots, and
|
||||
modules will automatically execute associated tests when loaded. Test results
|
||||
can be collected from ``/sys/kernel/debug/kunit/<test suite>/results``, and
|
||||
can be parsed with ``kunit.py parse``. For more details, see "KUnit on
|
||||
non-UML architectures" in :doc:`usage`.
|
||||
|
||||
If none of the above tricks help, you are always welcome to email any issues to
|
||||
kunit-dev@googlegroups.com.

This backend simulates an EEPROM on the connected I2C bus. Its memory contents

can be accessed from userspace via this file located in sysfs::

/sys/bus/i2c/devices/<device-directory>/slave-eeprom

The following types are available: 24c02, 24c32, 24c64, and 24c512. Read-only
|
||||
variants are also supported. The name needed for instantiating has the form
|

'slave-<type>[ro]'. Examples follow:
|
||||
|

24c02, read/write, address 0x64:
|

# echo slave-24c02 0x1064 > /sys/bus/i2c/devices/i2c-1/new_device
