The new implementation of kunit_test_suite() for modules no longer conflicts with module_init, so can now be used by the thunderbolt tests. Also update the Kconfig entry to enable the test when KUNIT_ALL_TESTS is enabled. This means that kunit_tool can now successfully run and parse the test results with, for example: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_USB4=y \ 'thunderbolt' Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Acked-by: Daniel Latypov <dlatypov@google.com> Acked-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: David Gow <davidgow@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

USB4 and Thunderbolt driver. USB4 is the public specification
|
|
based on the Thunderbolt 3 protocol. This driver is required if
|
|
you want to hotplug Thunderbolt and USB4 compliant devices on
|
|
Apple hardware or on PCs with Intel Falcon Ridge or newer.
|
|
|
|
To compile this driver a module, choose M here. The module will be
|
|
called thunderbolt.

Enables writing to device configuration registers through
|

debugfs interface.
|
|
|
|
Only enable this if you know what you are doing! Never enable
|
|
this for production systems or distro kernels.

help
|

This allows sending and receiving DMA traffic through loopback
|
|
connection. Loopback connection can be done by either special
|
|
dongle that has TX/RX lines crossed, or by simply connecting a
|
|
cable back to the host. Only enable this if you know what you
|
|
are doing. Normal users and distro kernels should say N here.
|
|
|
|
To compile this driver a module, choose M here. The module will be
|
|
called thunderbolt_dma_test.
