Hello!
I've got a Asus X370-Pro motherboard with enabled iommu. Unfortunately,
the group 0 is mostly all of the system :-).

I would like to put 0000:27:00.0 to a VM and 0000:24:00.0 to another VM
- but this isn't possible, because I had to unbind the other devices,
too - which is a bad idea and not possible, because I need them in the host.
Is there any chance to put these devices to different groups (because
they don't do any peer to peer communication e.g.)?
Thanks,
kind regards,
Andreas

Update your motherboard BIOS, AMD AGESA 1.0.0.6 is supposed to
enable ACS in the PCIe root ports. Thanks,

Group 0 is now group 10 - that's mostly all :-( - no significant change.
(Version 805 which should contain AGESA 1.0.0.6).

All devices that are used are in the same group again.
Isn't it possible to allow them to put to VM anyway if there is no peer
to peer communication - same as it was possible with the previous
chipset (990xa)?
Thanks,
Andreas

Ah, I see you have a PCIe switch with downstream ports 1d.*.0 where
the downstream switch ports don't support ACS (not surprising for
something reporting ASMedia as a subsystem capability). So ACS was
broken at multiple levels and now that it's exposed at the root port
it's still broken by the non-ACS switch. The endpoints downstream of
the switch are not sufficiently isolated to separate between VMs,
sorry, the hardware isn't up to the task at hand. Thanks,
Alex

In other words, you're telling, that there can't be done anything to get
it working? Do you know any other board, which doesn't have this problem
and could work?
Gigabyte? Asrock?

I have checked with the BIOS team, and they said that this is supposed to get
fixed in 1.0.0.7. Sorry for inconvenience.

We are now more than one year later now and there isn't any usable fix
out there. I'm using BIOS 4011 04/19/2018 on my Asus Prime X370Pro and
it's still impossible to put two pcie cards each to a different VM.
There is a small fix, but it's still unusable:

For me, device 0000:07:00.0 and 0000:08:00.0 is relevant - now they are both belonging to group 12.
Since more than a year I'm using the PCIe ACS overrides patch (pcie_acs_override=multifunction) to put those devices to two different VMs
and it always worked like a charme - I didn't had any problem so far (now using linux 4.18.6).
Could you please provide official pci quirks for this chipset?
Thanks,
Andreas
