A box booting Debian's Xen with an updated Debian 10/Buster setup as Xen's
dom0, a Ryzen CPU, Radeon-based GPU and an ASRock X450 Master SLI/ac
motherboard.
/etc/default/grub has been modified to include:
GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=1 amd_iommu=on"
and grub has been updated. SR-IOV is enabled in the BIOS.
After a reboot Xen reports:
# xl dmesg | grep IOMMU
(XEN) AMD-Vi: IOMMU Extended Features:
(XEN) AMD-Vi: IOMMU 0 Enabled.
Cool. But GNU/Linux says:
# dmesg | grep IOMMU
[ 2.536053] AMD IOMMUv2 driver by Joerg Roedel <jroedel@suse.de>
[ 2.536054] AMD IOMMUv2 functionality not available on this system
WTF?! Can someone whack me with a clue-bat? TIA.
