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.

Enables hardware and software based receiver lane margining support
|
|
under each USB4 port. Used for electrical quality and robustness
|
|
validation during manufacturing. Should not be enabled by distro
|
|
kernels.

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.
