However, hotplug will likely still not work, causing errors like: No bus number available for hot-added bridge. Once this is done, if you boot the server, the thunderbolt controller should show up in PCIe: $ lspci | grep 'USB controller'ДЈ7:00.0 USB controller: Intel Corporation JHL7540 Thunderbolt 3 USB Controller (rev 06) (Of course, never try to do any bridging while the device is powered on). Make absolutely sure that your card matches before attempting this, since incorrect bridging may damage your device. On other cards, the pinout of the GPIO may be different. Here's a picture of the correct pins to bridge. On the GC-Titan Ridge Rev 2.0 card, the appropriate pins to bridge are pins 3 and 5 (as counted from the bottom/left). For the first issue, the add-in cards have GPIO that, if bridged, will force power the Thunderbolt controller.

Reserve a PCIe bus number for any hotplug device to be addedДЇortunately, both of these can be worked around without requiring the manufacturer to provide a BIOS update.

Power on the Thunderbolt controller so Linux can recognize it.

In particular, the BIOS needs to perform two functions: The issue here is that many motherboard BIOSes do not properly initialize the Thunderbolt controller and thus Linux cannot make use of them. These instructions were tested on Ubuntu 21.04 with Linux kernel 5.11 and are likely not applicable to older kernels (which were missing patches). It's still extremely limited in support for AMD users, but hopefully, as time passes, more will get the certification and make it possible.There are many guides online for issues like these, but a lot of them are outdated, so hopefully, this is helpful for people encountering this issue in >= 2021. Besides super-fast data transfers, you can hook up accessories such as docks, external high-res displays, external GPUs, and even daisy chain together up to six devices. The advantage to Thunderbolt 3 is the incredible bandwidth that's possible down one single cable. And as with the X570 platform, you also get PCIe 4 support as well as Wi-Fi 6 here, too. Gigabyte bundles its GC-Titan Ridge PCIe expansion card with the motherboard, which opens up access to the Thunderbolt 3 connection. The implementation is a little less elegant than on the ASRock but still effective. If you're building something a bit more workstation-oriented, then you'll be looking for the Gigabyte TRX40 Designare, a motherboard for Threadripper systems that also supports Thunderbolt 3.

The USB-C port on the motherboard doubles as both USB 3.2 and Thunderbolt 3. ITX motherboards are inherently limited by their size, but if you're looking for Thunderbolt connectivity, this is the one.

The Phantom Gaming ITX TB3 also supports Wi-Fi 6 with an included antenna, and as it carries the AMD X570 chipset, you also get super-fast PCIe 4. This is mostly down to the space available, but it's a pretty incredible creation. This Mini-ITX board is something of a Frankenstein, not just because it carries Thunderbolt 3 certification, but because it also sacrifices the traditional AMD cooler mounting system in favor of Intel's. If you're building a Ryzen system, then you'll be needing the ASRock Phantom Gaming ITX TB3 motherboard.
