Setup
The script should work unmodified for Linux.
DirectHW.kext is required for PowerPC Macs running Mac OS X 10.4 or 10.5 (or any Mac OS X version).
DirectHW.kext may be required for Intel Macs running macOS 10.11 El Capitan or 10.12 Sierra.
Sierra might panic if you try the darwin2 access method.
It might work for Apple Silicon Macs without DirectHW.kext using the darwin2 access method but this is untested. DirectHW.kext on Apple Silicon Macs is also untested.
The darwin and darwin2 access methods of pciutils require nvram boot-args to include debug=0x144. If it does not, then add it:
sudo nvram boot-args="debug=0x144"
This may require SIP to be disabled, otherwise execute the command without sudo in Recovery's Terminal.app.
Don't forget to include the existing contents of boot-args inside the quotes.
The value used for debug= might not matter.
Download the script
cd ~
git clone https://gist.github.com/e3cd4ff08aae06279134969c98ca3ab7.git pcitree
cd pcitree
chmod +x pcitree.sh(Optional) Install pciutils (this example uses my fork)
If the lspci command doesn't exist already (likely for macOS but not Linux), then you need to install pciutils.
cd ~
git clone https://github.com/joevt/pciutils.git
cd pciutils
make
sudo make install
grep -q /usr/local/sbin /etc/paths || sudo sed -e $'1i\\\n/usr/local/sbin\\\n' -i "" /etc/paths
cd ~Create a new Terminal window to start using the new commands.
Occasionally, update the pciids database:
sudo update-pciidsTest the pciutils commands (-A detect is new option in my fork):
sudo lspci -A detect
sudo lspciFinally, try the pcitree script:
cd ~/pcitree
sudo ./pcitree.sh
I created a EFI driver called FixPCIeLinkRate.efi which also produces similar output to pcitree.sh. https://forums.macrumors.com/threads/opencore-and-the-2008-mac-pro-3-1.2287044/post-30087837

Tested in Ubuntu and macOS. Use it like this:
sudo pcitree.shOutput should look like this:
