The Designare uses the same JSL6540 chipset as the ASRock TB3 card he's using.@maleorderbride, got a few questions as well: your linked post mentions that method outlined in that post also works for x99 Designare EX. Is it reasonable to assume that it would also work for X299 Designare EX? Or is X299 Designare EX equipped with a different model of a TB chip? Would that even matter? I tried to search for a list of TB chip's models installed on x99/x299 motherboards, but haven't found any definitive point of reference.
Both DSM2 and I have tested his changes with a Designare X299, with no luck.
The biggest drawback with the designare (or any Gigabyte X299 motherboard with TB header for that matter), is that the thunderbolt must run from the PCH's PCIe lane.
This is a really dumb design if you ask me... That makes the PCH 4 PCI lanes shared for almost everything: thunderbolt, USB, NVMe, the lot....
The ASRock or Asus can use a CPU PCIe lane, and the Designare X99 also use CPU's PCIe lane.
So at present, I'm suspecting hotplug doesn't work on gigabyte boards, because of that difference
Edit: looks like @maleorderbride post got deleted, not wanting to get into the debate, but @kgp first SSDT thunderbolt, already contained the PCIHotplugCapable keyword that supposedly enable hot-plug many months ago...
