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. |

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. |
