Indeed I did, thanks! Now with it gone I still get the DMAR messages ... [ 4683.644755] DMAR: DRHD: handling fault status reg 3 [ 4683.703123] DMAR: [DMA Read] Request device [00:02.0] fault addr 8f440000 [fault reason 06] PTE Read access is not set [ 4683.831145] DMAR: DRHD: handling fault status reg 2 [ 4683.889487] DMAR: [DMA Read] Request device [00:02.0] fault addr 8f494000 [fault reason 06] PTE Read access is not set ... but I also get pass-through: [ 4870.366423] kvm: zapping shadow pages for mmio generation wraparound [ 4887.800200] vgaarb: device changed decodes: PCI:0000:04:00.0,olddecodes=io+mem,decodes=io+mem:owns=none [ 4887.800202] vgaarb: device changed decodes: PCI:0000:00:02.0,olddecodes=io+mem,decodes=io+mem:owns=io+mem No output yet. Is vgaarb looking correct above? 0000:04:00.0 is an R9 290. _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
