Cablecutter, I would encourage you to also open an AMD Support Ticket.  Enjoy, John.]]> Tue, 06 Mar 2018 22:45:51 +0000 https://forum.asrock.com/forum_posts.asp?TID=7863&PID=46825&title=x370-taichi-iommu-groups-bluetooth#46825 <![CDATA[X370 Taichi - iommu groups & bluetooth : Unfortunately, the specified ACS...]]> https://forum.asrock.com/forum_posts.asp?TID=7863&PID=46823&title=x370-taichi-iommu-groups-bluetooth#46823 Author: Cablecutter

Unfortunately, the specified ACS override did nothing. I've emailed ASRock support, but haven't received a response.]]> Tue, 06 Mar 2018 22:37:17 +0000 https://forum.asrock.com/forum_posts.asp?TID=7863&PID=46823&title=x370-taichi-iommu-groups-bluetooth#46823 <![CDATA[X370 Taichi - iommu groups & bluetooth : Also, may have found a workaround...]]> https://forum.asrock.com/forum_posts.asp?TID=7863&PID=46505&title=x370-taichi-iommu-groups-bluetooth#46505 Author: Cablecutter

Also, may have found a workaround for the pcie iommu issue. This can be added to the link config to try to break out hardware:


append pcie_acs_override=id:8086:24fb,1106:34B3

Haven't tried it yet.]]> Sat, 03 Mar 2018 05:09:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=7863&PID=46505&title=x370-taichi-iommu-groups-bluetooth#46505 <![CDATA[X370 Taichi - iommu groups & bluetooth : Thanks John, think I found it...]]> https://forum.asrock.com/forum_posts.asp?TID=7863&PID=46504&title=x370-taichi-iommu-groups-bluetooth#46504 Author: Cablecutter

It won't be listed there. From the Linux command prompt try

  lsusb -t

and

  lsusb -v

Thanks John,
Any idea which device might be the onboard Bluetooth?

The WiFi function is a PCIe v1.1 x1 device while the Bluetooth function is a USB v1.1 device.]]> Thu, 01 Mar 2018 09:35:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=7863&PID=46330&title=x370-taichi-iommu-groups-bluetooth#46330 <![CDATA[X370 Taichi - iommu groups & bluetooth : I don&#039;t know how many Linux...]]> https://forum.asrock.com/forum_posts.asp?TID=7863&PID=46206&title=x370-taichi-iommu-groups-bluetooth#46206 Author: JohnM

I don't know how many Linux users read these threads. I do know however that unRAID has a very supportive user group so you might get a more useful response if you ask there.

[URL=][/URL]Hi all,

I am using the x370 Taichi in a unRaid build with a Windows 10 VM. As such, I would like to pass through certain hardware to the VM, but have had trouble with IOMMU groupings, even when enabling ACS override in Linux. The GPU has worked out fine, but the hardware below has given me trouble:

#1) is the Bluetooth totally integrated with the wifi? Ie, wifi must be enabled in the bios to have Bluetooth. Passing through the wifi device should also pass through Bluetooth? Anyone know what the Bluetooth hardware would display when viewing iommu groupings in Linux?

#2) I have a pcie USB plugged in that I would like to pass-through wholesale for PnP support and better compatibility. Unfortunately, no matter what I try with ACS enable / ACS override in Linux it remains grouped with a lot of other hardware including the Ethernet adapter and main USB which cannot be passed through. Anyone know how to get around this?

VIA controller is the hardware in question:
