Hello All,

I'm new to VM's and Proxmox and I'm looking for some help to setup my home server via passing through 7 drives to a VM. I'm using this PCIe card which uses a sata controller (ASM1062 x4). However, it only seems to recognize when I'm not running with intel_iommu=on. I was able to pass through four drives successfully with a (Marvel 9215 x1) in the same machine earlier and had no issues with intel_iommu=on.

I'm trying to pass through the controllers in my IOMMU group 1. (The Marvel 9215 card was also group 1)

What gets me is that most reboots proxmox sees only my onboard NVME (sda), but occasionally some of the drives will show up under my pve disks (e.g. 4 of the 7 disks appear). I've never seen all 7 successfully show up with iommu=on. I've also tried allowing interrupts, but this didn't seem to do much.
(iommu_unsafe_interrupts.conf / kvm_iommu_map_guest.conf). And sometimes proxmox won't even boot up all the way and hangs at: pcieport 0000:00:01.0: AER: [ 0] RxErr.

Code: 
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"
(I've also tried adding iommu=pt w/o any luck here)

Also tried adding the below to a file in /etc/modprobe.d to use vfio-pci to no avail:
Code: 
options vfio-pci ids=1b21:0612

If I remove iommu from grub the disks and controllers seem to function correctly within proxmox. I only seem to be having issues when trying to passthrough. Any ideas or help here would be appreciated!!

What does lspci -tv show? It may need to be blacklisted, before it can be passed through. Also, is the bios up-to-date? And last but not least, you can add the device path of the disk to the config. This may be a workaround if passthrough isn't possible

Hi,

although this is not my thread I have a similar issue. How can I blacklist my ASM1062 controller?

options vfio_pci ids=1b21:0612 in a .conf-file in /etc/modprobe.d/ should do the trick (don't forget to run update-initramfs -u).
However, maybe the driver (which one you can find out with lspci -k) might be loaded before vfio_pci. You might need to add softdep ahci pre: vfio_pci. I don't think you want to blacklist ahci in general for all devices.

EDIT: Somewhere else on this forum, I noticed that the driver is ahci and updated this post accordingly.

Both SATA controllers use the same kernel module "ahci", so I guess blacklisting the module is not an option.
Which IDs should I use for options vfio_pci ids=1b21:0612 in my system? 0000:0400?
