added or modified. Instead, enable all tests
which have satisfied dependencies by adding
``CONFIG_KUNIT_ALL_TESTS=y`` to your ``.kunitconfig``.
+
+- ``--kunitconfig``: Specifies the path or the directory of the ``.kunitconfig``
+ file. For example:
+
+ - ``lib/kunit/.kunitconfig`` can be the path of the file.
+
+ - ``lib/kunit`` can be the directory in which the file is located.
+
+ This file is used to build and run with a predefined set of tests
+ and their dependencies. For example, to run tests for a given subsystem.
+
+- ``--kconfig_add``: Specifies additional configuration options to be
+ appended to the ``.kunitconfig`` file. For example:
+ .. code-block::
+ ./tools/testing/kunit/kunit.py run --kconfig_add CONFIG_KASAN=y
+
+- ``--arch``: Runs tests on the specified architecture. The architecture
+ argument is same as the Kbuild ARCH environment variable.
+ For example, i386, x86_64, arm, um, etc. Non-UML architectures run on qemu.
+ Default is `um`.
+
+- ``--cross_compile``: Specifies the Kbuild toolchain. It passes the
+ same argument as passed to the ``CROSS_COMPILE`` variable used by
+ Kbuild. This will be the prefix for the toolchain
+ binaries such as GCC. For example:
+
+ - ``sparc64-linux-gnu-`` if we have the sparc toolchain installed on
+ our system.
+
+ - ``$HOME/toolchains/microblaze/gcc-9.2.0-nolibc/microblaze-linux/bin/microblaze-linux``
+ if we have downloaded the microblaze toolchain from the 0-day
+ website to a specified path in our home directory called toolchains.
+
+- ``--qemu_config``: Specifies the path to a file containing a
+ custom qemu architecture definition. This should be a python file
+ containing a `QemuArchParams` object.
+
+- ``--qemu_args``: Specifies additional qemu arguments, for example, ``-smp 8``.
+
+- ``--jobs``: Specifies the number of jobs (commands) to run simultaneously.
+ By default, this is set to the number of cores on your system.
+
+- ``--timeout``: Specifies the maximum number of seconds allowed for all tests to run.
+ This does not include the time taken to build the tests.
+
+- ``--kernel_args``: Specifies additional kernel command-line arguments. May be repeated.
+
+- ``--run_isolated``: If set, boots the kernel for each individual suite/test.
+ This is useful for debugging a non-hermetic test, one that
+ might pass/fail based on what ran before it.
+
+- ``--raw_output``: If set, generates unformatted output from kernel. Possible options are:
+
+ - ``all``: To view the full kernel output, use ``--raw_output=all``.
+
+ - ``kunit``: This is the default option and filters to KUnit output. Use ``--raw_output`` or ``--raw_output=kunit``.
+
+- ``--json``: If set, stores the test results in a JSON format and prints to `stdout` or
+ saves to a file if a filename is specified.
