Linux 4.7 To Finally Support The First "Light Ridge" Thunderbolt Controller
While "Light Ridge" was the first copper Thunderbolt controller and released back in 2010, only now in 2016 is the first-generation controller seeing mainline Linux support.
Linux support for newer Thunderbolt devices have improved over time, but only for Linux 4.7 is there support for the Light Ridge first-generation controller being added to the mainline kernel. This Light Ridge copper controller (rather than being fiber-optic based) was found in the 2011 and some 2012 iMacs, Mac Minis, and MacBook Pro devices from Apple.
The PCI 4.7 updates are adding in this first-generation Light Ridge Thunderbolt controller support.
The patches for this support explain that there was a variety of issues with this early Thunderbolt controller but in the end it's just a few dozen lines of code changes for bringing it up on the modern Linux kernel.
