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
|

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.
