Xen users - Mar 2012 - Dear Tobias Geiger, I Need Help with Xen VGA Passthrough to Windows 8 Consumer Preview / XP (Xen 4.2-unstable)

Dear Tobia Geiger and Xen users and developers,

My Xen VGA Passthrough to Windows 8 Consumer Preview and Windows XP HVM 
domU is only *_partially_* successful. There is a yellow exclamation 
mark besides NVIDIA Geforce 8400 GS in Device Manager. Device Manager 
reports:

Windows has stopped this device because it has reported problems. (Code 43)

This device isn''t using any resources because it has a problem.

I suspect the above problem has to do with MMIO BARs pBAR:vBAR 1:1 mapping.

Could you read through my attached "Xen VGA Passthrough - Version 
1.6.pdf" documentation carefully to see if there are any mistakes in 
this area? Of concern are Sections 3, 4, and 6 in my Xen VGA Passthrough 
documentation.

I am using Xen 4.2-unstable changesets 25070 and 25099 and Linux Kernel 
3.3.0.

Thank you very much for your kind assistance.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)

Dear Teo,

your problem is "known". unfortunatly no "known" solution
exists.
of course you can try to find one - but that involves much try-and-error on 
your side. 
The "easy" solution would be: replace your NVIDIA card with a recent
ATI one.

Besides the fact that i can''t open your PDF (empty file...)
it''s really really
annoying - for various reasons; first: nobody can edit the PDF except you. 
second: now your pdf is stored in thousands of mailboxes in various versions - 
if it were a wiki-article or anything else web-based, it would be there only 
once. i love things which have a definite place...
please consider the suggestion many others already made to bring your good 
intended documentation effort to a technical state and place where everybody 
has the maximum profit of it: WIKI

Thanks and Greetings to Singapore!
Tobias

Dear Teo,

i mean your problem is know, but no known solution exists.
That doesn''t mean there is no solution, it just means nobody found one
yet :)

It''s spoken/written out many places (xen-devel/xen-users) that VGA
passthrough
with nvidia works ok with windows xp, but not with windows versions higher 
than xp. but it works with ati. 

to get to the actual problem:
you could try to also expose the "0xd30...- 0xd307fff" acpi regions.
no idea if that helps in any way i just saw that this is the only region 
you''re not mentioning in the patched dsdt.asl

good luck - but please try to accept the fact that nobody _knows_ the solution 
to your problem (well at least nobody i know of).

and about the pdf/wiki - ah... forget it

Greetings
Tobias

Dear Tobias Geiger,

Thank you for reading through my Xen VGA Passthrough Version 1.6 
documentation.

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.

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.

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...

Greetings
Tobias

Dear Tobias Geiger,

One final request from me: Can you check whether the Xen VGA Passthrough 
patches hosted at David TECHER''s official blog are the same as yours?

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.

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

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.

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)

i think you can safely buy a any of the 6xxx series. i would recommend a 
6870 or 6850, they are realtively cheap and quite fast.
i own a 6870 card a q67 board an a i5-2400s so i guess i could test it :)

maybe on the weekend ...

However, this configuration lacks the VBIOS passthrough, so one needs to use VNC
to install the drivers.  There is an old patch floating around that does ATI
bios passthrough, but it  would need to be forward ported.  That being said, I
never cared too much, since I can''t use my passthrough''d USB
keyboard to do anything in the guest until an OS loads with USB support.

Hmmm, actually, I wonder if seabios supports USB keyboards...

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.

Mr. Teo En Ming (Zhang Enming)

Objet : 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.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)

Dear Martin,

Please do test out Xen VGA Passthrough with your ATI Radeon 6870 and Xen 
4.2-unstable and let me know the test result.

After checking the computer hardware pricelist in Singapore, MSI R6870 
1GB DDR5 (2PM2D1GD5)........269, it costs S$269. Much much cheaper.

If you can get any cheap NVIDIA VGA card, please use/follow my Xen VGA 
Passthrough Version 1.6 Documentation and see if you can get Xen VGA 
Passthrough to Windows 8 Consumer Preview to work 100% successfully 
without any glitches. A cheap NVIDIA vga card like mine should cost only 
S$44.

Thank you very much for replying.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)

With ATI VGA cards, you still need to patch Xen 4.2-unstable? I thought Tobia
Geiger said that patches are not required?

Thank you very much.

you don''t *need* them, no. it works without them.

its just a little more hassle to install your windows until you can load 
the ATI driver. but thats - at least for me - done only once in a 
windows-hvm-domU-guest-lifetime, so i had no problem with that.

Greetings
Tobias

im not going to buy a nvidia card just for this case, thats ridiculous.
david techer and tobias geiger are far more competent with xen passthrough
than me, if they say it does not work as you expect, i guess you should 
believe them...

Dear Tobias Geiger,

Thank you for your confirmation. I may consider to get ATI VGA card, but 
not so soon. I am currently unemployed and I would hesitate to spend 
several hundred dollars.
