After reading many posts on GPU pass through failing on reboot of the domU, I questioned AMD and they responded with: This is the known and documented issue with hypervisor - Resolved issues (release notes) with driver 8.83.5.4 and above - May see system hang on restart with some hypervisors. Consider using a more recent firepro driver at support.amd.com. ray _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
Hi Ray! BIG THANKS for that information! I switched from the Catalyst Driver to this FirePro Driver - and the Reboot- Problems regarding GPU Performance are gone! Gladly this driver seems to work also for non FirePro-Cards, here it works with a Radeon HD 6970 without problems so far. Thanks for asking AMD - it never came to my mind it could be a driver-only solution for this problem...

Hi again, seems i was to early with my excitement - after another DomU Reboot the Performance is again degraded , even with the FirePro Driver :( After a cold boot i get about 3000 points in a 720p Benchmark (with a tool called "Furmark"), after a DomU reboot it gets down to 500 points... So - no real enhancement here even with the FirePro Driver Greetings Tobias Am Donnerstag, 23.
