tracking thunderbolt support for docks #2
Comments
@storrgie Not everything related to the docks is going to come from Intel's Thunderbolt software repository. Most of the fixes needed for the docks actually come from elsewhere in the kernel. The Thunderbolt software repository currently provides support for thunderbolt networking. A short summary of where things are today and what is needed to make things work:
Once you have all that above you can use the USB ports, the audio and the Ethernet in the dock. Video outputs will also work, but you'll probably be pushing i915 to it's limits if you try to hook up lots of displays. I'd expect any issues will be fixed directly in i915 and not in this repository. As for firmware updating:

Oh one more comment. The docks have a feature for MAC address pass through mentioned in that documentation. That's dependent upon this getting accepted: Feel free to follow along on that. |
Just checking back in on his because the updated BIOS was released. Did Dell release firmware updates for those docking stations? I've been running the AUR package for mainline, but still see a lot of problems with using the docking stations. One that I cannot consistently reproduce is packet loss to things on the local network when 'docked', or with any USB-C based NIC. |
@superm1 Is that summary only applicable to Thunderbolt on Dell BIOS? I assume the status isn't the same for Thunderbolt docks on Apple devices (I've read that Apple's BIOS leaves all the work to Apple's kernel driver). |
@storrgie Yes the new BIOS was released for all the platforms in the past month. |
@superm1 I've got 20 of the TB15 and 6 of these 7370. We've updated to the most recent BIOS this evening and will test again tomorrow. We're all on Linux so one thing I'm not sure about is if the TB15 is getting any updates from the 'drivers' that Dell releases. Do we have to boot one of these into windows and install all of the thunderbolt and dock drivers for each one of the TB15? Also, to go further off topic from this issue, do you know if there is any patches for support of the touchpad in the 7370? |
@storrgie For the touchpad you probably are looking for: It would really be better to bring this over to a thread somewhere else, feel free to open one up at the Dell sputnik forums and myself or someone else can comment on further questions. |
Is there a roadmap or plan for implementing Thunderbolt security in Linux? A lot of computers seem to lack the BIOS option necessary to disable it, and we're stuck without working TB3 at all. I have a Razer Core that I'd like to use on my Razer Blade Stealth or MSI GS63VR, and although it works perfectly in Windows on both machines, it is not detected on Linux with 4.9-rc on either due to security being forced. |
Thanks for reaching us on this topic . |
+1 for security features (or at least passthrough) on linux. |
Any updates to security features for 2017? Haven't seen anything in 4.13, so curious if this is still occurring. I'm using a tb16 dell dock with an xps15 on ubuntu17.04 and 4.11 kernel, just got it working, and was surprised to have to disable tb security. There are known bus attacks for macs via tb3 ports, so would be nice to have something to enable/authenticate security to get my ethernet/usb ports. |
Actually, kernel 4.13 supports secure connect of Thunderbolt devices, see kernel documentation here. And the new user-space SW here gives a nicer user interface instead of working directly with sysfs interface (and with ACL support for auto-authorize next time the device is connected), see the updated README here (displayed in the main page of the project). |
Ahh, this is very cool and good news! I need to look into seeing how compatible 4.13 is with everything on this xps15 dell, as finding a specific friendly kernel for nvidia was a trick in itself to play nice with gpu switching. Now probably just needs UI daemons to auth said TB-based devices upon request or cache per WM. |
UI is still missing, but if you want the same device to be approved next time, ACL, as mentioned. |
Dell has released a series of thunderbolt docking stations which seem to have issues in both Windows and Linux. It seems that Dell people, like @barton808, have mentioned that it's unclear when support will hit the mainline Kernel for devices of this nature. Is this repo a good spot to attempt to track Intel's work towards fleshing out the thunderbolt subsystems required to operate the Dell Docks?
