kernel by installing a production configuration of the kernel on production
hardware with a production userspace and then trying to exercise some behavior
that depends on interactions between the hardware, the kernel, and userspace.
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.

Linux I2C slave eeprom backend
Linux I2C slave EEPROM backend
==============================
by Wolfram Sang <wsa@sang-engineering.com> in 2014-15
by Wolfram Sang <wsa@sang-engineering.com> in 2014-20
This is a proof-of-concept backend which acts like an EEPROM on the connected
I2C bus. The memory contents can be modified from userspace via this file
located in sysfs::
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
24c512, read-only, address 0x42:
# echo slave-24c512ro 0x1042 > /sys/bus/i2c/devices/i2c-1/new_device
You can also preload data during boot if a device-property named
'firmware-name' contains a valid filename (DT or ACPI only).
As of 2015, Linux doesn't support poll on binary sysfs files, so there is no
notification when another master changed the content.

See chapter 6 (Functions).
For symbol names and documentation, avoid introducing new usage of
'master / slave' (or 'slave' independent of 'master') and 'blacklist /
whitelist'.
Recommended replacements for 'master / slave' are:
'{primary,main} / {secondary,replica,subordinate}'
'{initiator,requester} / {target,responder}'
'{controller,host} / {device,worker,proxy}'
'leader / follower'
'director / performer'
Recommended replacements for 'blacklist/whitelist' are:
'denylist / allowlist'
'blocklist / passlist'
Exceptions for introducing new usage is to maintain a userspace ABI/API,
or when updating code for an existing (as of 2020) hardware or protocol
specification that mandates those terms. For new specifications
translate specification usage of the terminology to the kernel coding
standard where possible.
