I'd suggest grabbing a Belkin Thunderbolt Express dock, they're $50 ish on eBay and include two tb3 ports among other things.

Which Thunderbolt Express Dock? The one I found has Thunderbolt 1 ports.

There's a Thunderbolt 3 Express Dock HD. It seems adequate. No DisplayPort 1.4 support and no ports that support 10 Gbps USB except the 2nd Thunderbolt port. I guess that's ok for someone who's only going to use it with a Thunderbolt 2 Mac that won't be using 10 Gbps USB and 20 Gbps NVMe at the same time.

Thank you for those scripts, they are very useful. I have attached the parsed output for ioreg -fliw0 below and provide the relevant BR10 within the code block below for reference.

I don't know what upstream or downstream you selected for that reading. If that's the downstream bridge connected to the NVMe then it means the NVMe did not negotiate a 8 GT/s x4 link correctly but you showed in a previous post that the NVMe was at 8 GT/s.

I was referring to the upstream bridge of the JHL 7540 (Titan Ridge) controller in the SSD enclosure. The downstream bridge of the Titan Ridge controller shows capabilities = negotiated = 4 x 8 GT/s which looks ok. Drilling down to the Samsung NVMe controller, the upstream capabilities = 4 x 16 GT/s (Gen 4) and negotiated = 4 x 8 GT/s (Gen 3) which is expected. So, if we ignore the PCIe link speeds for the bridges inside the tunnel, the slowest part of the PCIe link is 20 Gbps.

I was referring to the upstream bridge of the JHL 7540 (Titan Ridge) controller in the SSD enclosure. The downstream bridge of the Titan Ridge controller shows capabilities = negotiated = 4 x 8 GT/s which looks ok. Drilling down to the Samsung NVMe controller, the upstream capabilities = 4 x 16 GT/s (Gen 4) and negotiated = 4 x 8 GT/s (Gen 3) which is expected.
Click to expand...
I thought that might be the case, since Titan Ridge as a host controller can have 4 x 8 GT/s upstream but when I tried a Alpine Ridge based Thunderbolt dock, it showed capabilities and status of 4 x 2.5 GT/s. Retesting with a Titan Ridge based dock (Titan Ridge as a peripheral controller), I see the 4 x 8GT/s capabilities of the Titan Ridge upstream (4 x 2.5 GT/s status).

So, if we ignore the PCIe link speeds for the bridges inside the tunnel, the slowest part of the PCIe link is 20 Gbps.
Click to expand...
Yes. 5 GT/s x 4 for the upstream of the Falcon Ridge is the PCIe bottleneck that we can decipher from the PCIe info since all PCIe links upstream of that are 5 GT/s x 4 or greater, same for downstream PCIe links that are real. However, PCIe uses 8b/10b encoding so it's actually 16 Gbps. What we're missing is Thunderbolt info which should show that you are having a 10 Gbps bottleneck as PCIe must be tunnelled over Thunderbolt at two locations to get from your host to your NVMe. The info is probably in the Thunderbolt registers. Linux gives access to Thunderbolt devices in the sysfs and it gives access to Thunderbolt registers in the debugfs https://www.tonymacx86.com/threads/z490-z590-will-z590-ever-have-macos-support.308084/post-2235429
For macOS, you would need something like DirectHW.kext to get access to Thunderbolt registers. The Alpine Ridge and Titan Ridge Thunderbolt Interface Controller Datasheets have lists of registers. Most will be applicable to Falcon Ridge. The dumpthunderboltinfo.sh script dumps the Adapter Type from the Port Configuration Space of each port. The link rate and link width info is in the PHY Layer Config Registers capability of the Port Configuration Space of CIO ports. CIO ports have adapter type 00 00 01. Goshen Ridge has 8 CIO ports (2 lanes per USB-C port). Alpine Ridge and Titan Ridge have 4 CIO ports. The PHY Layer Config Registers are only 12 bytes. It has capability ID 1. There's probably a way to determine which CIO ports are bonded together or not and what direction they are connected (upstream/downstream in System Information.app) - maybe something to do with the path of each port.

These registers are very similar to the Lane Adapter Configuration Capability described in the USB4 spec. The USB4 spec is freely available and newer so it probably has better names for registers.

Was that a typo? Should be 1600 MB/s?
Click to expand...
I was referring to my test of a USB 10 Gbps device where I got 850 MB/s using Thunderbolt 1. A USB 10 Gbps device should be able to get ≈1060 MB/s.

1600 MB/s would be for a PCIe device (NVMe) device using Thunderbolt 2.

Theoretical max (without protocol overhead) for USB 10 Gbps is 10Gbps * 128b/132b = 9.697 Gbps = 1212.12 MB/s.
Theoretical max (without protocol overhead) for Thunderbolt 1 is 10 Gbps = 1250 MB/s.
Theoretical max (without protocol overhead) for PCIe 5 GT/s x 4 = 20 GT/s * 8b/10b = 16 Gbps. = 2000 MB/s.
Theoretical max (without protocol overhead) for Thunderbolt 2 is 20 Gbps = 2500 MB/s but Thunderbolt 2 controller is only PCIe 5 GT/s x 4.
Theoretical max (without protocol overhead) for PCIe 8 GT/s x 4 = 32 GT/s * 128b/130b = 31.5 Gbps = 3938 MB/s.
Theoretical max (without protocol overhead) for Thunderbolt 2 is 40 Gbps = 5000 MB/s but Thunderbolt 3 controller is only 8 GT/s x 4 and PCIe traffic is usually limited to < 24 Gb/s 3000 MB/s.

Thunderbolt uses 64b/66b encoding but the 10/20/40 Gbps numbers already take that into account - Thunderbolt actually uses 10.3125 or 20.625 MHz clocks.

Which Thunderbolt Express Dock? The one I found has Thunderbolt 1 ports.

There's a Thunderbolt 3 Express Dock HD. It seems adequate. No DisplayPort 1.4 support and no ports that support 10 Gbps USB except the 2nd Thunderbolt port. I guess that's ok for someone who's only going to use it with a Thunderbolt 2 Mac that won't be using 10 Gbps USB and 20 Gbps NVMe at the same time.

F4U095 is the one I was talking about, just a cheap way to get a powered tb3 port on a trash can MP. Other dock features not as important.

That is the version I have. I prepended the path to my installation of pciutils in the script:
Code: 
# Add path to pciutils directory
PATH="$HOME/Applications/pciutils/sbin${PATH:+:${PATH}}"

I cloned the pciutils repo and compiled the master branch. The last commit in the master branch is f19c33bfdfc5b106c1be5f4cc9b43b9cae8089d4.

Here is the output of -Adetect:
Code: 
barbie-en0:Mac Pro 6,1 stevenslupsky$ sudo lspci -Adetect
Password:
Trying method darwin......using AppleACPIPlatformExpert...OK
Trying method darwin2......using IOPCIBridge...OK
Trying method darwin3......cannot open DirectHW...No.
Trying method intel-conf1......DirectHW.kext not loaded...no I/O permission...No.
Trying method intel-conf2......no I/O permission...No.

Apologies, I think the output I posted earlier was generated before I realized that setpci was used multiple times in the script. I had prepended the path of the lspci and setpci commands with the path of the pciutils. When I realized my mistake I prepended the PATH instead.

Here is the (hopefully correct) pcitree.sh:

Which repo do you recommend for DirectHW.kext? Is there an OCLP option for installing it? Or, can I boot Linux in a VM and access the Thunderbolt registers that way?

There is not much info in System Information regarding the Thunderbolt port the OWC hub it attached to:

It is weird that the port works at all. The fact there is a PCIe tunnel using the Thunderbolt port and the SSD volumes are mounted but nothing appears in the Thunderbolt connections is odd. I found some fine print on the OWC web site last night that says "Thunderbolt/Thunderbolt 2 host connection is not supported".

I should point out that when my FTB (Sid's Franken Thunderbolt Apparatus == Apple adapter + HUB + SDD) is attached, boot time is affected ... there is an additional delay of about 30 or 40 seconds after the chime before the Apple logo appears. When verbose boot is turned on, there is no output for the same 30 or 40 seconds. I suspect this is the point at which the PCIe bridges are configured and the Thunderbolt devices are configured. Maybe there is some sort of timeout causing the Thunderbolt enumeration to fail at this point. Eventually the timeout expires, the volumes mount, Apple logo appears and the boot completes.

I think these screen shots show the downstream Falcon Ridge TB PCIe bridge (which is connected to the SSD) is linked to Thunderbolt Down adapter IOThunderboltPort@6:

pciutils expects the pci ids database to be at /usr/local/share/pci.ids.gz which is where the sudo make install command would put it. The database is used to get the Class and Device names.

I would use my fork of DirectHW.kext. OCLP doesn't have an option for DirectHW.kext since it's not needed to run any version of macOS on unsupported Macs. VM's in macOS can't access PCI devices such as Thunderbolt controllers. Maybe a VM in Windows or Linux can?

pciutils doesn't need DirectHW.kext for modern Intel Macs. pciutils needs it for PowerPC Macs and Apple Silicon Macs but I think it causes a kernel panic on Apple Silicon Macs. I don't have an Apple Silicon Mac to test or fix that.

DirectHW.kext can be used by flashrom to read or write ROMs of motherboards and PCIe cards on Macs. I haven't done much testing with flashrom.

As for Thunderbolt, I don't think DirectHW.kext is sufficient. To read Thunderbolt registers, a kext like DirectHW.kext would need to be created. A utility would use the kext to read the registers and output the information they contain.

At least you can see how to map the PCI Down Adapter (port 6) to the PCI device (DSB1) and vice versa using the PCI Path and Thunderbolt Path in each of those nodes. There's four PCI Down Adapters but only 2 Thunderbolt ports, so that means there's a way to get two PCIe 10 Gbps links per port? I don't think I've seen that before. Thunderbolt 1 has the same bandwidth as Thunderbolt 2 (20 Gbps) except that the bandwidth of any one Adapter cannot exceed 10 Gbps. I know Thunderbolt 1 can't connect a 16 Gbps display but can connect two 8 Gbps displays (because each display is on a different lane).

It's the difference between the EFI software and the macOS software. Or it's the difference between the built in Thunderbolt Connection Manager of the Thunderbolt controllers that gets used before macOS uses its own Thunderbolt Connection Manager. I'm not sure which Connection Manager is used before macOS starts. In order to boot from Thunderbolt, something has to set up the connections and that happens before macOS is booted.

Before the Apple logo appears is before macOS starts. Thunderbolt enumeration is succeeding during EFI which is how your NVMe is visible (though maybe verify that in the UEFI Shell of OpenCore). It's the macOS Thunderbolt software that is failing.

Thanks for the tip. Looks like that path is hard coded instead of relative so my local ~/Applications install does not find the database. I installed it into the standard directory.

I encountered a problem that was causing the pcitree.sh script to fail. lspci was truncating the output of a few lines in the tree:

I created an issue at the pciutils repo:
github.com

Long PCI ID causing truncation · Issue #139 · pciutils/pciutils

There are a few PCI vendor and device names when combined with the device codes (-nn option) causes a string length to exceed the size of the buffer and thus the output is truncated. For instance, ...
github.com github.com

Any idea where the link speed for the pcie tunnel is located? I suppose there would be two tunnels? Falcon Ridge to Goshen Ridge and Goshen Ridge to Titan Ridge?

Thanks for the tip. Looks like that path is hard coded instead of relative so my local ~/Applications install does not find the database. I installed it into the standard directory.

I encountered a problem that was causing the pcitree.sh script to fail. lspci was truncating the output of a few lines in the tree:

I created an issue at the pciutils repo:

Good catch. I should update my fork one day.

In the Thunderbolt registers that I listed at #30 . Check Negotiated Link Width and Current Link Speed. I have not researched how to access them. I would look at the linux code for the Thunderbolt debugfs. Each Thunderbolt device will have a link width / link rate for upstream (not the host) and downstream (not the last Thunderbolt device).

pciutils can only access the PCI config space (and extended config space) registers of the host Thunderbolt controller and any attached peripheral Thunderbolt controllers that were properly enumerated. If there's no fancy PCI config space register there that can address the Thunderbolt port config space registers, then you'll have to go through one of the BARs (probably of the NHI). flashrom can get access to BARs on macOS using DirectHW.kext. It does this for the satasii programmer for example but I don't like how it maps the BAR into its user space which is why I would suggest creating a kext dedicated to Thunderbolt probing.

Question: can the Thunderbolt port config registers of a peripheral Thunderbolt controller be accessed from the host Thunderbolt controller using some kind of path or does the peripheral Thunderbolt controller need to be enumerated into PCI config space first? I think a host Thunderbolt controller can get info from a downstream Thunderbolt without enabling PCI tunnelling. This is a security feature where the OS asks if you want to allow the newly connected Thunderbolt device to connect. Then the question becomes: can it access Thunderbolt controllers that are downstream to a downstream Thunderbolt controller where neither is enumerated into PCI config space?
