Xen project Mailing List

I am able to do it

Because

- you don't read the entire documentation that you are suppose to read. At the beginning of my article http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through it is written in "bold"

I am not the author who wrote the original patches. I've just tried to maintain the patches I found from Xen mailing-list. Since Summer 2011, I've begun to test Xen VGA PassThrough

- you are thinking that you know everything better than nobody. It works for XP with driver series 275.XX (againt in the same documentation). So if you want to test Windows XP with 29?.?? that's your problem!

Stop spamming us with your mails with your yellow mark and Windows XP. This is the same problem for Windows 8.

- you think that because there is a yellow mark on your graphic card on your device manager there is a problem with my patches. I've already test it all series 280.?? or 290.?? before you came with your stupid suggestions.

Conclusion: for Windows XP use driver 275.??

BUY A ATI AND STOP SPAMMING US WITH YOUR STUPID REQUESTS. I THINK I AM NOT ALONE IN THIS LIST WHO IS TIRED TO RECEIVE YOUR F??CK MAILS.

THIS IS MY LAST CONTRIBUTION AND NOW STOP SENDING MAIL TO ME OR CC MY NAME TO YOUR MAILS.

THANKS.

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.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)
