Hi everybody

I know there are plenty of posts on this subject, but I can't seem to solve my problem

My system:
HP DL380 G7
2 CPU xeon X5687 (4 cores / 8 threads, 3.6gHz)
48 Gbit DDR3
AMD firepro W2100

I try to place the firepro in a VM under windows 10.

QM config ID
Code:
balloon: 0
bios: ovmf
bootdisk: sata0
cores: 16
cpu: host

I followed this post
https://pve.proxmox.com/wiki/Pci_passthrough

When i execute this cmd: dmesg | grep 'remapping'
Code:
[    0.388593] DMAR-IR: This system BIOS has enabled interrupt remapping
               on a chipset that contains an erratum making that
               feature unstable.  To maintain system stability
               interrupt remapping is being disabled.  Please
               contact your BIOS vendor for an update

Hello,

Your GPU has loaded radeon driver so I think you cannot bind vfio on it.

in the guide, have you followed this section ?
Code:
echo "options vfio-pci ids=10de:1381,10de:0fbc" > /etc/modprobe.d/vfio.conf

and blacklisted radeon driver ?
Code:
echo "blacklist radeon" >> /etc/modprobe.d/blacklist.conf

if so, you should try adding grub options:
Code:
 video=efifb:off,vesafb=off
 
Also, please try with UEFI. Most cards work with UEFI, but don't with BIOS.

bios: ovmf
i have try the two solutions

Hello,

thank you
i have check all config and adding grub options

Take care, in your lspci for your GPU I can see
Code:
       Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+

That could lead to a code 43.
check in other posts how to enable MSI in windows guest VM
