Would this be the long awaited fix, that clears up following the concerns:
a) Peeps who wanted to buy & get stable VFIO/Passthrough functionality,
in threadripper but contemplating .
b) Concerns about it being a microcode/AGESA or silicon bug( like Ryzen Performance Marginality problem)
So… can I assume, that as far as every aspect of virtualization is concerned, the threadripper CPU’s silicon is good to go ? (and any missing functionality would have to do with the the OS catching up hereafter & maybe anyone can now buy a threadripper with their eyes closed )
Hi all, first post after reading/following this site and the youtube channel for about half a year now! My name is Paul, and ultimate goal at the moment is I’m trying to convert myself to using Linux full-time as my main environment.
Just posting to introduce quickly and add another confirmation here - I’ve managed to replicate everything described above and the patch works! Thankyou to all who are clearly devoted to getting this working as best as it can, wendell, geoff “gnif” etc.
I consider myself a bit of a newbie still on most things Linux, so I wrote up a small “guide” whilst I was figuring everything out - from livecd install to a working VM with GPU passthrough, if anyone is interested. I’ve gone through it about 5 or 6 times by now, tweaking it each time, initially to make my own life easier not having to remember the exact order of steps. Might be useful to someone!
Also managed to encounter and then work around the code 43 issue, so now I have 2 identical nVidia GPU’s, both connected to the same monitor (this feels wrong!) - the nouveau driver only grabs one GPU and I can pass through the other to a Windows VM and install working Windows nVidia drivers on there.
Anyway, just saying hi, and thanks!
Attached is the guide, my very first one so be brutal! Audio pass-through is still a bit dodgy, but I managed to figure out how to get Nvidia drivers installed on both Fedora and Windows, in place of nouveau, and wayland seems to work fine as well.
Let me know if this should be it’s own thread/out of the way: fedora-threadripper-gpu-passthrough.txt (20.2 KB)

Be prepared to wait about 20 mins, and your fans will go nuts, in my experience anyway!
Ignore cat broken pipe errors. Pretty much ignore all errors that come up if it gets past the first few bits.
If this doesnt work, try running fedpkg switch-branch f27, edit kernel.spec again, ensure tr.patch is present and then do fedpkg local. I have had better results on f27 - it now downloads kernel 4.15 and builds as 4.15, not 4.16, as I imagine you are seeing by now.
[[email protected] kernel]$ fedpkg switch-branch f27
Could not execute switch_branch: /home/kevin/kernel has uncommitted changes. Use git status to see details

Your branch is up-to-date with ‘origin/master’.
Changes not staged for commit:
(use “git add …” to update what will be committed)
(use “git checkout – …” to discard changes in working directory)
(use “git add …” to include in what will be committed)
Wait until the current build is done before trying to change anything or you’ll have a mess to deal with…
Should be fine to do another build afterwards, but youll notice it creates .rpm files in /root/kernel and /root/kernel/x86_64. When I was figuring all this out, I would delete them so I didn’t get confused when installing the second/third build I was trying.
When done and you switch-branch, you will indeed still get the git error - I see you tried to fix it, but it’s the other option you want. If you want to commit I think you need to setup a git account and it commits it to the git website (I’m not a developer, I’ve never used git, someone educate us please!).
Anyway just discard the changes, that means it will delete tr.patch and restore kernel.spec to original so have tr.patch elsewhere:
I’m new here. Normally just a forum lurker, but I felt compelled to make an account to thank @wendell, Geoff, and everyone else who made this possible.
Comp sci student, 1 year Linux convert. As a fellow person who gets anxiety running Windows on bare metal, but a programmer not nearly adept enough to do this on his own, I really appreciate this.
To many of my university peers, Linux is just a box you put inside of WIndows or Mac. Projects like these have potential to turn that on its head. Thank you.
