[vfio-users] Intel PCH ACS quirks on Z97

Tue Sep 29 12:06:37 UTC 2015

I am using ASRock Z97 Extreme6 and want to pass devices connected to the
PCIe from PCH.
The problem is all PCIe root hubs are in one VFIO group. Do the Intel PCH
ACS quirks work for Z97? The IDs are in the quirks.c
Are there some restriction that prevent quirks to activate?

Thanks
Pixo
