Re: [Xen-users] Dear Tobias Geiger, I Need Help with Xen VGA Passthrough to Windows 8 Consumer Preview / XP (Xen 4.2-unstable)
Dear Tobias Geiger, Thank you again for replying to me.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.

i can only say for sure that it works with a "Radeon HD 6970" - thats what 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 cards working - but don't take any older ones. that said i can only tell for sure it works with the mentioned 6970 - simply because i haven't tested any other cards yet myself. regarding the patches - they should be the same, as he claims somewhere that 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.

David Techer told me it's a NVIDIA driver issue, which I don't think so. I seriously wonder what's wrong with the glitch. I am using NVIDIA driver version 296.17 for Windows 8 Consumer Preview. Xen VGA Passthrough to Windows 8 Consumer Preview: I can watch Youtube videos with audio/sound and surf the internet as well. But I just can't run 3d graphics benchmarks. Only 2d graphics benchmarks can be run. By the way, I have only recently bought this Palit NVIDIA Geforce 8400 GS at SGD$44. If I buy an ATI card, what would you recommend that is CHEAP? Must be PCI Express x16. Then do you think the Xen VGA Passthrough patches are necessary any more? Please refer to the computer hardware pricelist here http://www.fuwell.com.sg/uploads/misc/Fuwell240312.pdf and recommend me a cheap ATI card. Preferably SGD$50. Finally, Xen VGA Passthrough to Windows XP Home Edition also has the yellow exclamation mark glitch with NVIDIA Geforce 8400 GS. With Xen 4.2-unstable. Thank you very much.Hi Teo, sorry to hear that it didn't help. Unfortunatly thats all the hints i'm able to give you - from now on you're out there alone so to speak :) Good luck - or (even on the danger of repeating myself:) just buy an ATI card...

I am now trying out your suggestion, i.e. expose the 4th memory range. When I refer to David Techer's official blog and his emails, he only mention the first 3 memory ranges. When I asked David Techer what about the 4th memory range, he said nothing. Let's hope I get lucky and get the yellow exclamation mark with NVIDIA Geforce 8400 GS (ie Xen VGA Passthrough to Windows 8 Consumer Preview *PARTIAL* success) FIXED. By the way, what is the problem with my Xen WIKI? Xen.org administrator Mr. Lars Kurth edited my Xen Wiki pages for me. If it works, I will have Xen VGA Passthrough Version 1.7 documentation and FINAL as well. Thank you very much for reading through my documentation and giving me suggestions. I hope it works now.Dear Tobias Geiger, I have just exposed the 4th memory region, patched dsdt.asl, recompiled and reinstalled Xen 4.2-unstable but IT STILL DOESN'T WORK. There is still a yellow exclamation mark besides NVIDIA Geforce 8400 GS in Xen VGA Passthrough to Windows 8 Consumer Preview. I still cannot run 3d graphics benchmarks. Only 2d graphics benchmarks can run. Please read through my Xen VGA Passthrough Version 1.6 documentation again to see if there are any mistakes. Please. Please. Please. I want to fix that glitch. Any more ideas? I hope some expert engineers at Intel Corporation (Han Weidong, Zhang Xiantao, and Ren Yongjie) can fix this glitch with Xen VGA Passthrough to Windows 8 Consumer Preview. They are after all the original authors/developers who wrote the Xen VGA Passthrough patches. But Han Weidong has left Intel Corp, I think. He was still at Intel 3 years ago. Thank you very much. Eagerly awaiting your reply.
