Yes, a vague ideaAny ideas?
The two upper PCIe slots are connected to the CPU and may be used with passthrough. The two bottom slots are connected to the chipset.Not 100% sure but i think its the bottom pci slot which shares storage controller.

reporting?If you passed through the device, you must also add option to the denylist.conf...if you don't the kernel blocks the passthrough...see here: ttps://forum.proxmox.com/threads/pve-blacklist-conf-not-working.134895/#post-596612Encouraged by this i started to configure radeon vii passthough and final result was black screen and no boot![]()
There is a nice website that lets you look up your board when you don't have access to your Proxmox, or someone else's IOMMU groups ;-)My set up is:
Gigabyte Auros master x570

Thank you, but i think something got messed when i blacklisted radeon vii. When i verified everything results werent identical as in instructions at forums so that could possibly be it.For reference, the term I could not recall just before I see on screen now: IOMMU group.

Im using this guide to proceed : https://forum.proxmox.com/threads/p...x-ve-8-installation-and-configuration.130218/Thank you, but i think something got messed when i blacklisted radeon vii. When i verified everything results werent identical as in instructions at forums so that could possibly be it.
dmesg | grep -e IOMMU
that IOMMU is enabled i should get this line as in guide:*dmesg | grep -e IOMMU
dmesg | grep 'remapping'
dmesg | grep vendor_reset
:dmesg | grep vendor_reset
dmesg | grep -E "DMAR|IOMMU"
dmesg | grep 'remapping'
dmesg | grep -i vfio
lspci -nnk | grep 'AMD'
systemctl status vreset.service
I told you in post #5...IOMMU will not show enabled until you create a vfio_pci.conf and add the option below...Dont know how to continue from this point, can anyone please help me with this? Thank you
I dont quite follow now, all my IOMMUS show. My problem is vendor reset doesnt activate.I told you in post #5...IOMMU will not show enabled until you create a vfio_pci.conf and add the option below...
GNU nano 7.2 /etc/modprobe.d/vfio-pci.conf
options vfio-pci disable_denylist=1
Once enabled, you set/attach to the VM : qm set VMID -hostpciX 0f:00,pcie=on
where VMID equals for example 100, 101, 102, etc., and -hostpciX equals the pcie slot,
then you run: update-initramfs -u -k all
Your pci device is now passed through...
so, running this cmd "dmesg | grep -e DMAR -e IOMMU" shows enabled? Do you only have one pci graphic card?I dont quite follow now, all my IOMMUS show.
It doesn't show as in mine: [ 0.170241] DMAR: IOMMU enabled...root@homelab:~# dmesg | grep -e DMAR -e IOMMU
[ 2.432268] pci 0000:00:00.2: AMD-Vi: IOMMU performance counters supported

I guess you have intelIt doesn't show as in mine: [ 0.170241] DMAR: IOMMU enabled...
That's was I want to see.
Yes...isn't the same with AMD when IOMMU is enabled?I guess you have intel
Yes...isn't the same with AMD when IOMMU is enabled?
From this: https://pve.proxmox.com/wiki/PCI_Passthrough
There should be a line that looks like "DMAR: IOMMU enabled". If there is no output, something is
Newer amd has iommus on by default. If it wouldnt work i wouldnt have hba card passthrough working for truenas.Yes...isn't the same with AMD when IOMMU is enabled?

Yes, thats how it shows on intel.Well, I don't know then...to me, if IOMMU is on by default, it should show in Proxmox "DMAR: IOMMU enabled".
Proxmox needs a new wiki for pci passthrough...
