Any new updates ?
Last I saw was that the 5.2 Kernel should have support. The 5.4 Kernel was released in Nov 2019.
Anyone tried it ?
Adding to the excitement of the Linux 5.2 kernel changes are a lot of Thunderbolt improvements expected to be introduced in this next kernel cycle.
Mika Westerberg of Intel has been working on a lot of Thunderbolt connectivity improvements destined for Linux 5.2 and in recent days has begun staging this work in the thunderbolt-next tree ahead of the Linux 5.2 kernel merge window opening in May.
This work includes support for full PCIe daisy chaining within the Thunderbolt software connection manager:
Currently the software connection manager (tb.c) has only supported creating a single PCIe tunnel, no PCIe device daisy chaining has been supported so far. This updates the software connection manager so that it now can create PCIe tunnels for full chain of six devices.
