ThundeBolt 3/ USB C UEFI drivers

[Amit kumar]

Hi,
I have some queries.
1. Does ThundeBolt 3 and USB C shave the same uefi drivers ?
2. Is there any driver in UEFI for them ?
3. Do they use USB Mass Storage Driver ?
4. Do they support booting like USB 3.1 /3.0 / 2 ?

Thanks And Regards
Amit

Amit,

I don't know of any open source drivers for ThunderBolt. 

ThundeBolt 3/ USB C share a connector, but they are different technologies. Conceptually they are sharing a Phy. 

USB C (vs. USB A) is just a different connector and USB basically works the same way it always did. There might be some chipset specific code required to configure the Phy. 

A ThunderBolt  link makes PCI show up on the other side of the ThunderBolt link. After the ThunderBolt link is initialized extra PCI devices can be discovered by the system and it works a lot like plugging in a PCIe card. 

Thanks,
