Is it possible I am missing some of the components to the GPU that may be in another IOMMU group?

[AMD] Family 17h (Models 10h-1fh) HD Audio Controller Seems like it should be just group 8 but why would it work when I don't have the sound card and not work when I add the sound card unless it's not the right mix... maybe?

What have you tried so far? I am in the same situation except I haven't installed my 5700G yet. As I understand it, there are some steps to remove access of it to the main system and get it passed through to vfio. From there, it should populate in the GPU/Sound card slots when making a VM. If you are lucky it might just work.

I do only have gigabit LAN but internally perhaps it would be bottlnecked. Found this one instead which shouldn't be bottlnecked: https://www.newegg.com/p/2WG-00UP-007H3

So with 6 port configurations, it would be roughly 150-175 MB/s on a 1x lane? That seems like a reasonable max for a HDD. Certainly not for an SSD but do spinning disks ever need more than that amount of bandwidth?

This upgrade also broke all the paths for VM disks... There is no /mnt/user option anymore?

Had to change paths back to what they were (probably) ...

Jeeze, this stuff is so finicky. I wanted the x1 so I wouldn't have to use one of the three PCIe x16 slots but how much is x1 going to bottleneck? I would just be using standard 5400 or 7200RPM spinning disk drives.

It was enabled and running before the upgrade but now I see this:

@JorgeB So to be clear this one will be fine? https://www.newegg.com/p/17Z-00EK-00DA6 PCI-E x1 to 6 Ports SATA3.0 Adapter Expansion Card PCIe SATA Controller for HDD Support 10T 12T Above ASMedia ASM1166 Miner Card With 2U High and Low Profile Bracket Does it matter that it's labeled as a miner card? Is the max hard drive size it support 10T or 12T (rather ambiguous there)

Hah, no kidding - how can you tell? What about either of the products in the first post? I thought they both were port multiplied but now I have no idea how to tell.

This one looks good but isn't specifically whitelisted for UNRAID as far as I can tell: https://www.newegg.com/riitop-pcex1ts-6p-sata-iii/p/14G-001D-00008 SATA Expansion Card 6Port, RIITOP PCI-e x1 to SATA Hard Drive Controller Card Adapter, Come with Low Profile Bracket (JMB575+ASM1062 Chipset)

I could be misunderstanding but going off of what @JonathanM indicated, the description has this:

This one uses the ASMedia ASM1166 chip but has a port multiplier... It seems like I have to comb through quite a few things to find compatible hardware. That's why I was hoping someone could just point me to some good hardware. https://www.newegg.com/p/17Z-00EK-00DA6

I don't really like to use ebay - can you link to something on newegg, amazon, or another US online retailer? What is the 6 port one?

I did view that link but didn't see any non-SAS 8 port controllers recommended. I was hoping to avoid SAS as it looks a lot more complicated. Is there no recommended standard 8 port SATA controller?

https://smile.amazon.com/Splitter-Controller-Expansion-Standard-Profile/dp/B097SHTR84 Would this one work ? No text indicating a port multiplier as far as I can see but am unsure if it requires a system driver to work. ("Supports Windows 7/ 8.1 / 10 / Linux, install the driver before add the HDD in system ")

Gotcha. Supports Port Multiplier was a little vague but means it uses them (as indicated in lower product description). Still looking then, any good alternative suggestions?

Edited: Many seem to have port multipliers but a 6 port ASM1166 chip controller on at least PCIe x2 or higher should be good. (see last post for link)

Is there any other information I can provide to help figure out why it's not working?

I was able to boot a Ubuntu VM (OVMF Q35 5.1) with only the video device passed through (no sound counterpart) and the system worked for 2 subsequent boots with 3D acceleration (but no sound). I then added the sound device pass-through and it stopped booting. I made the Space Invader special XML tweak that seems to be a long-standing bug that isn't fixed yet. The system looks like it boots and I can even see the teamviewer alias pop into the list but it is inaccessible and the GPU has no output. I can get it back to booting by removing the sound device and restarting unraid (tested once - I maybe had to boot with VNC vga once first too before reassigning the passthrough GPU). I am booting unraid in UEFI (tried legacy boot also) System has an APU (Ryzen 5 2400G) as primary GPU & passthrough GPU in first PCIe slot IOMMU forced enabled in bios (GPU reserved in unraid for vfio) I have tried with or without the specified ROM vbios file (pulled manually from a bare metal windows boot and the techpowerup utility) VM log: -overcommit mem-lock=off \ -smp

Yeah that makes sense. I did try to decipher the manual but it was very unclear when it comes to this configuration so I was hoping for someone who may be better informed than myself to weigh in. This is the 'spec': Integrated in the CPU (PCIEX16/PCIEX8): 1. 3rd Generation AMD Ryzen™ processors: 1 x PCI Express x16 slot, supporting PCIe 4.0 and running at x16 (PCIEX16) 1 x PCI Express x16 slot, supporting PCIe 4.0 and running at x8 (PCIEX8) 2. 2nd Generation AMD Ryzen™ processors/3rd Generation AMD Ryzen™ with Radeon™ Graphics processors: 1 x PCI Express x16 slot, supporting PCIe 3.0 and running at x16 (PCIEX16) 1 x PCI Express x16 slot, supporting PCIe 3.0 and running at x8 (PCIEX8) * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot. * The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When using the 3rd Generation AMD Ryzen™ processors/2nd Generation AMD Ryzen™ processors and PCIEX8 slot is populated, the PCIEX16 slot operates at up to x8 mode. 3. 2nd Generation AMD Ryzen™ with Radeon™ Vega Graphics processors/1st Generation AMD Ryzen™ with Radeon™ Vega Graphics processors: 1 x PCI Express x16 slot, supporting PCIe 3.0 and running at x8 (PCIEX16) Integrated in the Chipset (PCIEX4/PCIEX1): 1 x PCI Express x16 slot, supporting PCIe 4.0*/3.0 and running at x4 (PCIEX4) * For 3rd Generation AMD Ryzen™ processors only. 2 x PCI Express x1 slots, supporting PCIe 4.0*/3.0 * For 3rd Generation AMD Ryzen™ processors only. It's actually a lot clearer here than it was in the manual so it does seem to indicate that I get just one PCIe x16 (running at x8). So it looks like the 2400G is just a terrible matchup... Looks like I need to wait for a gen3 iGPU/APU.

@Celsian Does this setting have any bearing on the configuration requirements? It set to UEFI Only by default: Description below seems to indicate that it excludes relevancy to video devices.

Wow - humbled by the quick and thorough support - thanks everyone!

I have a tiny 16GB USB as a disk1 driver and that's it for the main array pool. The cache pool has two m.2's. I thought I set to use cache only for the shares but its not very straight forward to manage what is on the data disk (I have no idea) yet it has 9GB or so used now. How do I erase that content and make sure it's stored on the cache pool instead? My shares look like this: Looks like it's isos that are somehow mapped to the disk drive but the settings are the same for each share (use cache pool for new files/folders). Seems to have bugged out and flipped back somehow?
