If Radeon HD 6970 is guaranteed to work with Xen VGA Passthrough to = Windows 8 Consumer Preview, I may get it, maybe a few months down the = road. But it costs Singapore dollars $479!!! I don't think I may be getting it SOON. My NVIDIA Geforce 8400 GS costs = only S$44 and I only bought it recently. If I want to stick with Xen VGA Passthrough to Windows 8 Consumer = Preview with NVIDIA Geforce 8400 GS, then only Intel engineers Zhang = Xiantao, Ren Yongjie and Xen developers may be able to help me fix the = yellow exclamation mark glitch. Seriously do you think there may be a problem with the MMIO BARs = pBAR:vBAR 1:1 matching? Is David Techer a software = engineer/programmer/developer? If not, how is he able to forward port = Intel's Xen VGA Passthrough patches from Xen 3.5-unstable (WHICH WORKED = 100% SUCCESSFULLY) to Xen 4.2-unstable (which worked only PARTIALLY = successfully for MYSELF)? Thank you again for proof-reading my Xen VGA Passthrough Version 1.6 = documentation. If somebody is able to help me fix the glitch, there will = be a FINAL Version 1.7 documentation. -- = Yours sincerely, Mr. Teo En Ming (Zhang Enming) Singapore On 27/03/2012 22:53, Tobias Geiger wrote: > i can only say for sure that it works with a "Radeon HD 6970" - thats wha= t i'm > using. stay away from dual-gpu cards, they have a more complex pci-bus > structure which may not work when passed-through. > The newer 7XXX may also work, i also think i read something about 5XXX ca= rds > working - but don't take any older ones. > that said i can only tell for sure it works with the mentioned 6970 - sim= ply > because i haven't tested any other cards yet myself. > > regarding the patches - they should be the same, as he claims somewhere t= hat > he took mine and forward-ported them to a then recent xen version. > > With the ati card above you don't need any patches at all. none from david > techer, none from ati. pure vanilla xen (4.X or unstable) is enough. > > Greetings > Tobias > > > Am Dienstag, 27.
