Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.Are other chips better than ASM1166? In other forums I see, that on newer motherboards there is an option "ACS enable" in BIOS. Is enabling ACS in BIOS as unsecure as patching the kernel with the acs patch?

Like.
The X570 (and X570S) chipset have proper IOMMU groups (so no override needed). Of course most PCIe and M.2 slots will still go through (and be limited by) the chipset. EDIT: Turns out that the TUF GAMING X570-PLUS (WI-FI) does not have two x16... -

Yes. That's correct. *If you're connecting two GPUs, converting the CPU-connected M.2 to Oculink and using it as an eGPU might work...

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.Thank you, then I will do it so. The ACS patch is for me too much risk, because the ethernet adapter is also in the big chipset group on B550. I'm simply not experienced enough to reliably assess the risk of the ACS patch for myself. Therefore...

We have confirmed operation on the A520. It should also work on the B550. If the IOMMU group on the chipset's PCIe lanes matches other devices, setting ACS should allow it to function without issues.

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.Thank you. Or I only use one GPU for passthrough. And use a M.2 to SATA adapter in an M.2 slot connected to the CPU for passthrough this to an TrueNAS VM. This passthough should even work on B550 withouth ACS-patch, because it is connected to...

Upon closer inspection, it's definitely x4 from the chipset... My mistake, sorry. I really need a block diagram...

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.Thank you so much. It was my mistake to buy it. Now I don't want to buy used anymore and will buy a B550 and patch it with ACS. Are all B550s equally compatible with the ACS patch, or are there differences in how well the patch works?

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.Ohh, I think this is not so ... :( The second PCIe x16 is only an x4 from X570 chipset. And in the manual I don't find, that I can split the 16 lines to 8/8. So I guess I now have one of the few X570 boards where it won't work. I just have no...

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.I had the change to get a cheap x570 over a forum. So i bought a ASUS X570 TUF gaming plus Wifi. I hope, that with this board a dual GPU passthrough will work in combination with pasthrough of an PCIe HBA.

Yes, but unfortunately, many devices of the big chipset group are accessible-from/have-access-to the Proxmox host (like the network, drive and USB controllers and more). Your VM can, in principle, read all of the host memory (and therefore all of...

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.I've spent several hours now looking into the ACS patch. Initially, I had serious security concerns, but if I understand correctly, the risk depends on many factors. If I use the patch, than the memory management group is ignored and every PCI...

It only states what speeds and lanes are available for each slot when using Vermeer or Matrisse. It does not specify that they are connected to the CPU (nor that they are in a separate IOMMU group)...

It is not possible with the 24 PCIe lanes from the AM4 socket. Where does it say that it is connected to the CPU? The website only shows which slots with which speed and lanes works when which Ryzen family is installed. It does not say how they...

Bbrightrgb reacted to leesteken's post in the thread [SOLVED] I need help setting up double gpu passthrough with Like.
Only the first PCIe x16 slot and the first M.2 slot (which is like PCIe x4) are usually connected to the CPU and can be used for PCI(e) passthrough. What makes you think the second slot will put a GPU (or other PCIe device) in a separate IOMMU...

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.It's really crazy. The MSI B550-A Pro seems to be the only board that has two PCIe slots connected to the CPU and not End Of Life. Unfortunately, for some reason, the MSI doesn't support ECC. :( I'd even be happy with a second PCIe slot, even...
