There is neither an official AMD statemant nor a confirmation on this issue.
You have spoken to an AMD developer? What they told you?
I mean the only thing beeing of interest is how long it will take to be fixed
1 month?, 1 year?, another 10 years?, never?
I mean this issue is not only about GPU passthrough, all PCI-E devices I've
tested are affected, those are:
-SATA-Storage-/SAS-Raid-Controller-Cards (slow-downs/hangs in transfer)
-PCI-E SSDs (slow-downs/hangs in transfer)
-Network-Cards (slow-downs/hangs in transfer)
-TV-Cards (hangs in (hardware decoded) streams)
