[REQUEST] Request for Xen Users to Attempt Jean David Techer's Xen 4.2-unstable VGA Passthrough Documentation

[Teo En Ming (Zhang Enming)]

[-- Attachment #1.1: Type: text/plain, Size: 4482 bytes --]

Dear Xen Users,

I have _partial_ (that is, less than 100%) success following Jean David 
Techer's Xen 4.2-unstable VGA Passthrough Documentation. In both Windows 
8 Consumer Preview HVM and Windows XP Home Edition HVM, I get yellow 
exclamation mark besides NVIDIA Geforce 8400 GS in Device Manager. 
NVIDIA Geforce 8400 GS in Device Manager reports:

1) Windows has stopped this device because it has reported problems. 
(Code 43)
2) This device isn't using any resources because it has a problem.

So, in Xen VGA Passthrough to Windows 8 Consumer Preview HVM and Windows 
XP Home Edition HVM, I can only surf the internet and watch Youtube 
videos but I cannot run 3D graphics benchmarks. This is very very 
important because you cannot play 3D games. I can only run 2D graphics 
benchmarks, meaning I can only play 2D games. But nobody plays 2D games 
nowadays.

Jean David Techer, who is French, told me that it is a NVIDIA driver 
problem. According to his documentation, you have to use NVIDIA drivers 
275.33 and 275.50 strictly. Any other NVIDIA driver versions WILL NOT 
work. Hence, I have attempted to install NVIDIA drivers 275.33 WHQL and 
275.50 BETA in Windows XP Home Edition HVM domU. Common sense tells you 
I did not install both driver versions at the same time, of course. 
Installing NVIDIA driver versions 275.33 and 275.50 causes Windows XP 
Home Edition HVM domU to be DESTROYED (in Xen speak) and also causes my 
domain 0 to crash.

But if I install the LATEST NVIDIA drivers above 280.XX, it WILL NOT 
cause my Windows XP HVM domU and domain 0 to crash. But there will be a 
yellow exclamation marks besides NVIDIA Geforce 8400 GS in Device 
Manager. Why do I keep complaining about the yellow exclamation mark? Is 
it because I have nothing better to do and irritate David Techer? It is 
because I simply CANNOT run 3D graphics benchmarks and play 3D games. I 
can only surf the web and play Youtube videos.

Jean David Techer's Xen 4.2-unstable VGA Passthrough documentation is 
available at the following URL:

Jean David Techer's Blog link: 
http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through

Any Xen user with the following computer hardware specifications, please 
try out David Techer's documentation.

Intel Processor with Virtualization Technology
Motherboard with VT-d support
Motherboard BIOS with VT-d option to enable or disable
NVIDIA PCI Express x16 display card

Any Xen user who can attain 100% success with David Techer's Xen 
4.2-unstable VGA Passthrough documentation, please let all of us at 
xen-users mailing list know.

Why do I keep on troubleshooting? Because I consider this to be a 
technical challenge, although I am not an expert programmer. I have only 
learnt very basic C programming more than 15 years ago at Singapore 
Polytechnic and I have forgotten most of it by now. I am a Linux/UNIX 
system administrator with experiences in Apache web server, qmail and 
Postfix Email Server, DNS Server, DHCP server, OpenLDAP server, phpBB 
forum, MySQL database, Xen virtualization, VirtualBox, VMware, Snort 
Intrusion Prevention Systems, OSSEC Host Intrusion Detection Systems, 
Nagios monitoring software, and various Linux and BSD distributions. But 
I am by no means a software developer. I did not study computer science. 
I studied mechanical engineering at National University of Singapore.

It is too bad software engineer Han Weidong has left Intel Corporation 
last year, otherwise he would be able to help me. I got 100% success 
with Xen 3.5-unstable VGA Passthrough 3 years ago, back in the year 
2009. Han Weidong et al are the original developers of the Xen VGA 
Passthrough patches, which only worked with Xen 3.5-unstable. Jean David 
Techer forward ported Han Weidong's patches to Xen 4.2-unstable with his 
programming knowledge, C/C++ and Java. I have read his CV.

According to Intel engineers Zhang Xiantao and Ren Yongjie, Intel's 
current policy is to focus on IGD VGA passthrough, so it is understood 
that they won't be able to help me with my issue. It is company policy, 
so they cannot afford the time and resources to help me.

If everybody who follows Jean David Techer's Xen 4.2-unstable VGA 
Passthrough documentation with 100% success without glitches, then I 
must be technically incompetent.

I would like to thank Xen users in advance if they are able to lend a 
helping hand.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)

Dearest Casey DeLorme,

Thank you very very much for your kind feedback and input. I would also 
like to thank Mr. Tobias Geiger, again, for providing his suggestion on 
exposing the fourth memory region in 
tools/firmware/hvmloader/acpi/dsdt.asl. _In any case, either exposing 
the first 3 memory regions only or exposing all the 4 memory regions 
does not work._ Sadly, Tobias Geiger is unable to help me further.

I have asked Jean David Techer, what about the 4th PCI memory region? 
Why only expose the first 3 PCI memory regions? I don't understand, of 
course. Jean David Techer did not reply to my question.

I have decided to post your prompt reply to the xen-users and xen-devel 
mailing lists, in case people think that I am finding fault with Jean 
David Techer, or trying to irritate him, or trying to make him angry, or 
trying to aggravate him. Jean David Techer replied me with an email 
saying that I _spent too much time_ and _too bent_ on solving the yellow 
exclamation mark glitch for my NVIDIA Geforce 8400GS in Device Manager 
in Windows 8 Consumer Preview and Windows XP Home Edition, and that I 
sent *_stupid_* requests. Stupid requests? Did he read my emails 
carefully, word by word?

Casey DeLorme, please, can I confirm with you again that you are getting 
the following errors after applying Jean David Techer's Xen 4.2-unstable 
VGA Passthrough patches:

*_(1) Yellow exclamation mark besides your NVIDIA GTX 460 in Device Manager
(2) Windows has stopped this device because it has reported problems. 
(Code 43)
(3) This device isn't using any resources because it has a problem._*

Jean David Techer insists that our technical issues are due to a NVIDIA 
driver problem. He insists that you have to install NVIDIA driver 
versions 275.33 WHQL and 275.50 BETA. Any other NVIDIA driver versions 
(above 280.XX) will not work, according to Jean David Techer. *_However, 
I have tried installing NVIDIA driver versions 275.33 and 275.50 from 
www.softpedia.com, as he suggested, but it caused my Windows XP Home 
Edition HVM virtual machine to be destroyed/terminated/crash after a few 
minutes and my dom0 to crash as well._* NVIDIA driver versions 275.33 
and 275.50 for Windows XP 32-bit is not available from the official 
NVIDIA website.

So it is definitely not a NVIDIA driver problem. I suspect that the 
technical issue has to do with *_MMIO BARs pBAR:vBAR 1:1 matching_*. I 
don't think there is any problem with vgabios-pt.bin extracted out from 
our NVIDIA VGA cards, because I have performed a "hexdump -C" on my 
extracted VGA BIOS EEPROM, or Electrically Erasable Programmable Read 
Only Memory.

Secondly, it does seem strange that Jean David Techer was able to attain 
*_100%_*, ie. *_perfect success_* with Xen 4.2-unstable VGA Passthrough 
to his Windows XP 32-bit and 64-bit HVM domU. Have you watched his 
Youtube video? It is only 4 minutes. Please do watch Jean David Techer's 
Youtube video at the following URL:

Jean David Techer's Xen 4.2-unstable VGA Passthrough to Windows XP x64 
HVM domU Youtube video link: *_http://www.youtube.com/watch?v=3SaYO0ERW44_*

I am *_appalled_* and *_baffle__d_* that he has attained *_100% 
success_* while both of us have only attained *_partial succes__s_* 
(*_i.e. less than 100%_*) on Xen 4.2-unstable VGA Passthrough to Windows 
8 Consumer Preview and Windows XP.

*_Solving the yellow exclamation mark issue is important because we 
would not be able to run 3D graphics benchmarks and play 3D games 
without solving it. I am not sending silly emails about some yellow 
marks, as Jean David Techer suggested. I can't even run Unigine Heaven 
DX11, and 3dmark11 3D display benchmarks, because of the yellow 
exclamation mark for NVIDIA Geforce 8400 GS in Device Manager._*

Casey DeLorme, with your report on relatively easy success with ATI VGA 
cards, I think I would go the ATI way, but I would have to spend a few 
hundred dollars compared to my cheap SGD$44 NVIDIA Geforce 8400 GS card. 
And while deciding to go the ATI way, I would also like to continue 
troubleshooting with the NVIDIA problem, because I consider it to be a 
technical challenge.

In essence, Jean David Techner is considered to be a "boss", or business 
owner, or proprietor, or technopreneur, or entrepreneur, or technical 
support officer, or customer support officer, or IT helpdesk engineer, 
providing services like his forward-ported Xen 4.2-unstable VGA 
Passthrough patches and the documentation on his blog. I repost Jean 
David Techer's official website here:

Jean David Techer's Xen 4.2-unstable VGA Passthrough blog: 
*_http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through_*

Jean David Techer's official website is his business venture.

Basically, I am Jean David Techer's *_"customer"_*, trying to obtain 
technical support from him. Of course, he is *_not obliged_* to provide 
technical support to me since he is providing *_free_* services. It is, 
after all, an open source software project. Nobody is obliged to provide 
anybody with technical support. *_To do Jean David Techer justice, he 
replied most of my questions while avoiding some of my questions._*

Finally, I have also failed to obtain technical support from Xen 
developers like Ian Campbell from *_Citrix Corporation_* and Konrad Wilk 
from *_Oracle Corporation_*. _*I have always provided all the steps 
which I have taken, the configuration files and necessary documentation, 
and kernel messages and error logs*_ to xen-users and xen-devel mailing 
lists, but they keep insisting I did not provide the information they 
required. I wondered why. I think they did not read my emails carefully. 
They told me they would not reply to me any more if I do not provide the 
information they requested. _*But the problem is that I have always 
provided information they requested!*_ I think they missed some of my 
emails, or did not read my emails carefully enough. I am an *_ardent 
supporter_* and *_SERIOUS software tester_* for open source Xen 
virtualization/hypervisor but they treated me lightly. _*I always read 
my emails WORD BY WORD.*_ I have even went to the point of making a 
video on the *_BUG_* and uploading my video to Youtube. The video is 
only THREE minutes.

_*As everybody says, a picture is worth a thousand words. A video is 
worth a BILLION words!*_

I have also failed to obtain technical support from Xen developers 
regarding Xen 4.2-unstable VGA Passthrough.

I am hoping Xen 4.2 would have official support for Xen VGA Passthrough 
for both NVIDIA and ATI cards.

Casey DeLorme, thank you very much once again. I will be making changes 
to my Xen, Linux Kernel and Xen VGA Documentation and will be releasing 
Version 1.7 shortly. Jean David Techer's documentation assumes some 
level of advanced Linux technical knowledge, so I am writing 
documentation on my own so that everybody, not just advanced Linux and 
Xen users, can follow. I have made references to Jean David Techer's 
documentation in my own documentation.

I would be very happy if people would use my documentation. Of course, 
it satisfies my ego and my vanity. Haha.

I have been un-employed for nearly three years now, and I would hesitate 
to spend a few hundred dollars on an ATI VGA card. I quit my job as an 
IT engineer 3 years ago because my father suffered from lacunar infarct, 
or more commonly known as stroke. My NVIDIA Geforce 8400 GS costs only 
S$44. Please understand why I hesitate to buy an ATI VGA card. The 
cheapest one costs SGD$279.

I have a diploma in Mechanical+Electronics engineering from Singapore 
Polytechnic and a Bachelor's degree in Mechanical Engineering from the 
National University of Singapore. But I do not have qualifications in 
Computer Science or Information Technology. I have worked as an 
Information Technology engineer in Defense Science and Technology 
Agency, Ministry of Defense, Singapore, National Computer Systems Pte 
Ltd, Asiasoft Online Pte Ltd, and Ishinemax Singapore Pte Ltd.

Dearest Casey DeLorme,

Thank you very very much for your kind feedback and input. I would also 
like to thank Mr. Tobias Geiger, again, for providing his suggestion on 
exposing the fourth memory region in 
tools/firmware/hvmloader/acpi/dsdt.asl. _In any case, either exposing

developers like Ian Campbell from *_Citrix Corporation_* and Konrad Wilk 
from *_Oracle Corporation_*. _*I have always provided all the steps 
which I have taken, the configuration files and necessary documentation, 
and kernel messages and error logs*_ to xen-users and xen-devel mailing 
lists, but they keep insisting I did not provide the information they 
required. I wondered why. I think they did not read my emails carefully. 
They told me they would not reply to me any more if I do not provide the 
information they requested. _*But the problem is that I have always 
provided information they requested!*_ I think they missed some of my 
emails, or did not read my emails carefully enough. I am an *_ardent 
supporter_* and *_SERIOUS software tester_* for open source Xen 
virtualization/hypervisor but they treated me lightly. _*I always read 
my emails WORD BY WORD.*_ I have even went to the point of making a 
video on the *_BUG_* and uploading my video to Youtube. The video is 
only THREE minutes.

_*As everybody says, a picture is worth a thousand words. A video is 
worth a BILLION words!*_

I have also failed to obtain technical support from Xen developers 
regarding Xen 4.2-unstable VGA Passthrough.

I am hoping Xen 4.2 would have official support for Xen VGA Passthrough 
for both NVIDIA and ATI cards.

Casey DeLorme, thank you very much once again. I will be making changes 
to my Xen, Linux Kernel and Xen VGA Passthrough Documentation and will 
be releasing Version 1.7 shortly. Jean David Techer's documentation 
assumes some level of advanced Linux technical knowledge, so I am 
writing documentation on my own so that everybody, not just advanced 
Linux and Xen users, can follow. I have made references to Jean David 
Techer's documentation in my own documentation.

I would be very happy if people would use my documentation. Of course, 
it satisfies my ego and my vanity. Haha.

I have been un-employed for nearly three years now, and I would hesitate 
to spend a few hundred dollars on an ATI VGA card. I quit my job as an 
IT engineer 3 years ago because my father suffered from lacunar infarct, 
or more commonly known as stroke. My NVIDIA Geforce 8400 GS costs only 
S$44. Please understand why I hesitate to buy an ATI VGA card. The 
cheapest one costs SGD$279.

I have a diploma in Mechanical+Electronics engineering from Singapore 
Polytechnic and a Bachelor's degree in Mechanical Engineering from the 
National University of Singapore. But I do not have qualifications in 
Computer Science or Information Technology. I have worked as an 
Information Technology engineer in Defense Science and Technology 
Agency, Ministry of Defense, Singapore, National Computer Systems Pte 
Ltd, Asiasoft Online Pte Ltd, and Ishinemax Singapore Pte Ltd.

Re: [Xen-users] [REQUEST] Request for Xen Users to Attempt Jean David Techer's Xen 4.2-unstable VGA Passthrough Documentation

[Teo En Ming (Zhang Enming)]

[-- Attachment #1.1: Type: text/plain, Size: 9201 bytes --]

Dearest Casey DeLorme,

Thank you very very much for your kind feedback and input. I would also 
like to thank Mr. Tobias Geiger, again, for providing his suggestion on 
exposing the fourth memory region in 
tools/firmware/hvmloader/acpi/dsdt.asl. _In any case, either exposing 
the first 3 memory regions only or exposing all the 4 memory regions 
does not work._ Sadly, Tobias Geiger is unable to help me further.

I have asked Jean David Techer, what about the 4th PCI memory region? 
Why only expose the first 3 PCI memory regions? I don't understand, of 
course. Jean David Techer did not reply to my question.

I have decided to post your prompt reply to the xen-users and xen-devel 
mailing lists, in case people think that I am finding fault with Jean 
David Techer, or trying to irritate him, or trying to make him angry, or 
trying to aggravate him. Jean David Techer replied me with an email 
saying that I _spent too much time_ and _too bent_ on solving the yellow 
exclamation mark glitch for my NVIDIA Geforce 8400GS in Device Manager 
in Windows 8 Consumer Preview and Windows XP Home Edition, and that I 
sent *_stupid_* requests. Stupid requests? Did he read my emails 
carefully, word by word?

Casey DeLorme, please, can I confirm with you again that you are getting 
the following errors after applying Jean David Techer's Xen 4.2-unstable 
VGA Passthrough patches:

*_(1) Yellow exclamation mark besides your NVIDIA GTX 460 in Device Manager
(2) Windows has stopped this device because it has reported problems. 
(Code 43)
(3) This device isn't using any resources because it has a problem._*

Jean David Techer insists that our technical issues are due to a NVIDIA 
driver problem. He insists that you have to install NVIDIA driver 
versions 275.33 WHQL and 275.50 BETA. Any other NVIDIA driver versions 
(above 280.XX) will not work, according to Jean David Techer. *_However, 
I have tried installing NVIDIA driver versions 275.33 and 275.50 from 
www.softpedia.com, as he suggested, but it caused my Windows XP Home 
Edition HVM virtual machine to be destroyed/terminated/crash after a few 
minutes and my dom0 to crash as well._* NVIDIA driver versions 275.33 
and 275.50 for Windows XP 32-bit is not available from the official 
NVIDIA website.

So it is definitely not a NVIDIA driver problem. I suspect that the 
technical issue has to do with *_MMIO BARs pBAR:vBAR 1:1 matching_*. I 
don't think there is any problem with vgabios-pt.bin extracted out from 
our NVIDIA VGA cards, because I have performed a "hexdump -C" on my 
extracted VGA BIOS EEPROM, or Electrically Erasable Programmable Read 
Only Memory.

Secondly, it does seem strange that Jean David Techer was able to attain 
*_100%_*, ie. *_perfect success_* with Xen 4.2-unstable VGA Passthrough 
to his Windows XP 32-bit and 64-bit HVM domU. Have you watched his 
Youtube video? It is only 4 minutes. Please do watch Jean David Techer's 
Youtube video at the following URL:

Jean David Techer's Xen 4.2-unstable VGA Passthrough to Windows XP x64 
HVM domU Youtube video link: *_http://www.youtube.com/watch?v=3SaYO0ERW44_*

I am *_appalled_* and *_baffle__d_* that he has attained *_100% 
success_* while both of us have only attained *_partial succes__s_* 
(*_i.e. less than 100%_*) on Xen 4.2-unstable VGA Passthrough to Windows 
8 Consumer Preview and Windows XP.

*_Solving the yellow exclamation mark issue is important because we 
would not be able to run 3D graphics benchmarks and play 3D games 
without solving it. I am not sending silly emails about some yellow 
marks, as Jean David Techer suggested. I can't even run Unigine Heaven 
DX11, and 3dmark11 3D display benchmarks, because of the yellow 
exclamation mark for NVIDIA Geforce 8400 GS in Device Manager._*

Casey DeLorme, with your report on relatively easy success with ATI VGA 
cards, I think I would go the ATI way, but I would have to spend a few 
hundred dollars compared to my cheap SGD$44 NVIDIA Geforce 8400 GS card. 
And while deciding to go the ATI way, I would also like to continue 
troubleshooting with the NVIDIA problem, because I consider it to be a 
technical challenge.

In essence, Jean David Techner is considered to be a "boss", or business 
owner, or proprietor, or technopreneur, or entrepreneur, or technical 
support officer, or customer support officer, or IT helpdesk engineer, 
providing services like his forward-ported Xen 4.2-unstable VGA 
Passthrough patches and the documentation on his blog. I repost Jean 
David Techer's official website here:

Jean David Techer's Xen 4.2-unstable VGA Passthrough blog: 
*_http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through_*

Jean David Techer's official website is his business venture.

Basically, I am Jean David Techer's *_"customer"_*, trying to obtain 
technical support from him. Of course, he is *_not obliged_* to provide 
technical support to me since he is providing *_free_* services. It is, 
after all, an open source software project. Nobody is obliged to provide 
anybody with technical support. *_To do Jean David Techer justice, he 
replied most of my questions while avoiding some of my questions._*

Finally, I have also failed to obtain technical support from Xen 
developers like Ian Campbell from *_Citrix Corporation_* and Konrad Wilk 
from *_Oracle Corporation_*. _*I have always provided all the steps 
which I have taken, the configuration files and necessary documentation,

Dear Casey DeLorme,

This guy, Sebastien Gauthier, also has the same problems as us. He was 
using Xen 4.1.0 and an ATI Radeon 4550. He applied Mr. Wei Huang's 
patch. After installing the latest ATI/AMD Catalyst drivers, he got a 
BSOD with Xen VGA Passthrough to Windows 7.

Please read Sebastien Gauthier's case here:

http://readlist.com/lists/lists.xensource.com/xen-users/11/59090.html

Hence Sebastien Gauthier reported Xen VGA Passthrough with PARTIAL 
SUCCESS, like us.

Dear Tobias Geiger,

You were saying that with ATI VGA cards, you do not need to apply any 
Xen VGA Passthrough patches. But this guy Sebastien Gauthier applied Mr. 
Wei Huang's patches to Xen 4.1.0 and got a BSOD after installing ATI 
Catalyst drivers. Sebastien Gauthier did not get 100% success with Xen 
VGA Passthrough to Windows 7 using an ATI VGA card.

Re: [Xen-users] [REQUEST] Request for Xen Users to Attempt Jean David Techer's Xen 4.2-unstable VGA Passthrough Documentation

[Teo En Ming (Zhang Enming)]

[-- Attachment #1.1: Type: text/plain, Size: 18348 bytes --]

Dear Casey DeLorme and Tobias Geiger,

It appears that Xen users requesting for assistance on VGA Passthrough 
are not getting any help from the Xen developers at all. Every time 
somebody asks for help on Xen VGA Passthrough, the Xen developers keep 
quiet and won't reply.

Please read Thomas Richard's case here:
http://marc.info/?l=xen-devel&m=127713854025100&w=2

Casey DeLorme,

Thomas Richard also had the same problems as us.

[QUOTE=Thomas Richard]

I got pretty excited when reading about the VGA Passthrough features in
>>  Xen 4.0 so i decided to give it a go. I've had partial success, like some
>>  other in here. I've got output on my VGA port but my windows HVM guest
>>  reports that the VGA doesn't work. Windows XP says: Couldn't start device
>>  (10) and Windows 7 says: Windows has stopped the device because it reported
>>  problems (40).
[/QUOTE]

Thomas Richard also reported PARTIAL SUCCESS with Xen VGA Passthrough, like us.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)
Singapore

Hi Teo,

The VBIOS patch I sent out did not work for all ATI cards. The patch 
itself assumed certain behavior of GPU VBIOS. But this doesn't apply to 
every GPU generation. From this perspective, my patch isn't universal. 
Also there are many factors, some of which are not in control by us 
(like graphics driver), can contribute to BSOD you mentioned. I am not 
in a position to debug it for everyone's card (as I don't have all cards).

Thanks,
-Wei

Re: [Xen-users] [REQUEST] Request for Xen Users to Attempt Jean David Techer's Xen 4.2-unstable VGA Passthrough Documentation

[Casey DeLorme]

[-- Attachment #1.1: Type: text/plain, Size: 19477 bytes --]

David,

XenServer VGA Passthrough requires a paid/licensed copy, which costs $2500,
a bit out of my price range for experimentation.  Important to note that
the feature is not a part of the 30-day trial license.

However, Citrix recently visited my college and I was able to preview
hardware access on a laptop one of the employees had, where they swapped
between Ubuntu and Windows with a hotkey, and various hardware components
including onboard GPU and the WebCam were accessible.

In testing XenServer, I can say that if I had a business, that's the
product I would use.  In the past month having tried Xen and ESXi, I was
astonished with the ease of use for XenServer.

As for Catalyst, version 12.2 (the latest currently) worked for me.

Important to note that until I followed Andrews advice to omit the Catalyst
Control Center, the installation resulted in a BSOD.

The solution, select "Custom" installation and uncheck the CCC.  After the
installation your first reboot should run some follow-up updates via cmd,
you need to reboot a second time for fully functional drivers.

Also, I had underscan on my monitor so I went out on a limb and re-ran the
setup for Catalyst, and was able to get CCC installed with a second run
through, which allowed me to fix my underscan issue.

My conclusion is that the CCC requires some driver functionality that isn't
available until after you install the drivers, this could be on all systems
or it might be related to how HVM's handle the PCI devices, that much I
can't say.



Teo,

I could be spouting nonsense, and if so I'm sure Wei can correct me, but I
am pretty sure AMD engineers have been contributing to Xen for a while, and
some patches have already been applied.  Obviously it isn't flawless, I
myself haven't gotten video at boot time, only at the login screen.

Mine works on 4.1.2, but it is possible that 4.1.0 had less of these
"patches" hence Sebastien's post.

Also, I apologize as I did not properly word my opinion before.  VGA
Passthrough is new "for consumer components".  In 2010 the number of
desktop (not server) boards boasting VT-d functionality could probably be
counted on one hand.  To my understanding that means the technology is at
most 3 years old, still a baby in my opinion.

I didn't mean that the technology hadn't been implemented into various
Hypervisors, just that it is clearly not a perfected feature.  If you
consider 3 years of consumer availability, dates become important when
researching.  Sebastien's post was May 2011, just shy of one year ago, and
Thomas's was in 2010.

There are newer patches still for ATI in Xen 4.2, which I intend to test
over the next week.  I have NOT gotten ATI to work at boot time, video
starts at the login screen.

I agree with Wei that drivers can contribute to BSOD's and errors, but when
an install doesn't fail but the hardware reacts the same as before, I would
like to assume the driver is irrelative.

I saw similar issue whiling playing with XenClient. After discussing 
with AMD GPU driver team, the conclusion was that the installer has a 
bug. But I have not received any further update from them. Also manual 
driver installation (after many tries) did fix problem for me.

This is because VBIOS patch wasn't applied. But as I said before, my 
VBIOS wasn't universal enough to put it as a production patch. So I am 
hesitant to put it out.

Have you looked at XenClient project? It has a customized ATI component 
which allows you to switch between VMs flawlessly. I think it is the 
most mature Xen solution for GPU passthru in client area.

Dear Mr. Wei Huang at AMD Corporation,

Thank you very much for your kind reply.

I want to buy the following ATI Radeon VGA card. Do you think it would 
work with your Xen VGA Passthrough patch to Xen 4.2-unstable???

Sapphire HD5450 512MB             Singapore Dollars $55

I am a cheapskate when it comes to spending money.

If your Xen VGA Passthrough patch to Xen 4.2-unstable works with the 
above ATI VGA card, I will go ahead and buy it. Do I have to manually 
patch Xen 4.2-unstable or is your patch already included in Xen 
4.2-unstable source tree?

Secondly, I have a request/favor to ask of you. Do you think it is 
possible for you to examine the Xen 4.2-unstable VGA Passthrough patches 
hosted at Jean David Techer's website and check if it is compatible with 
Xen 4.2-unstable code?

Thirdly and finally, could you read through my Xen VGA Passthrough 
Version 1.7 documentation to see if there are ANY MISTAKES with NVIDIA 
Geforce 8400 GS VGA Passthrough, because I am only getting PARTIAL SUCCESS.

If you could write Xen VGA Passthrough patches, you are an expert 
software engineer.

Thank you very very very much.

Dear Casey DeLorme,

I am sorry to say that I don't quite understand by what you say when you 
state that you haven't got ATI VGA card to work at boot time, video 
starts at the login screen. I am puzzled.

Do you think you could record your Xen VGA Passthrough computer with a 
video camera and upload your video to Youtube so that I can watch it?

Thank you very much.

Dear Wei Huang at AMD Corporation,

Please put your Xen VGA Passthrough patch out so that all of us can have 
a try.

Thank you very much.

I don't have HD5450 card. So I can't test it and can't answer your 
question directly. If I have some time later, I will test other HD5xxx 
cards and test you the result. Normally GPUs of same family behave 
similarly.

My patch was against QEMU. It is not included in the tree.

Re: [Xen-users] [REQUEST] Request for Xen Users to Attempt Jean David Techer's Xen 4.2-unstable VGA Passthrough Documentation

[Casey DeLorme]

[-- Attachment #1.1: Type: text/plain, Size: 21788 bytes --]

Wei,

I was not aware that XenClient sported such features, I would be more
interested if I could find pricing on XenDesktop.  Unfortunately they want
me to go through a sales call process, which I believe means expensive.

Perhaps when their distribution process allows for online purchases I may
reconsider.  It is at least good to know that they have specialized ATI
features.



Teo,

I will be sure to post a video when I complete my re-installation.

When booting an HVM it goes through a POST process, then the Windows 7
loading screen, I do not see any of this on my monitor.

However, I can see it through a VNC connection.

I only get video after Windows 7 has loaded, generally at the User Login
menu.

The way I understood it was my VGA Passthrough is a secondary GPU not the
primary, though I am unaware of any specific benefits to make it the
primary card.

As for Xen 4.2 Unstable patches, David's blog has numerous posts compatible
with different Xen 4.2 unstable revisions.  The latest full guide seems to
be for revision 24869:

Afaik XenServer only supports GPU passthru with certain "pro" GPUs - not consumer models.

And here you're talking about XenClient, which is a totally separate product for laptops.
XenClient does a lot of tricks to share the (consumer) GPU between VMs,
including the V4V framework to copy GPU data between VMs.

Isn't it better than nothing? More GPU support could be added later?

Hi,

i was looking hard to get this thing working, and i somehow manage to get
two ATI graphic card working under Windows 7 and Debian 6 DomU,
what i learn from all this trying, that the most important thing is the
motherboard!
i had i7 860 with VT-D, but it was hard to find working VT-D motherboard, i
try gigabyte P55-USB3 with beta bios from gigabyte and i got working 3D
drivers for a few minutes and then the DomU would crash,
then i wanted to try asus, but they said that P55 chipset doesnt support
VT-D functions, then i look what David uses and get a MSI motherboard and
its default bios has got VT-D to enable/disable
currenty i have:
i7 860
MSI P55 GD85
ATI H6670 - working 3D
ATI H5830 - working 3D
Debian 6.0, custom kernel 3.1
Xen 4.2 unstable ( from repo 2. march? )
Windows 7 64bit - virtual
no extra patches

but how i get it to work is strange, if i enable #gfx_passthru=1 then
virtual machine wont start, but if its disabled it starts with virtual
graphic and ATI, but with the primary the virtual graphic
and when i install lates ATI drivers and reboot the machine, it use the ATI
as the primary graphic and the virtual graphic has ! on it.
i testes with 3D test, even play a game on it, and it works! but as soon i
uninstall the drivers it goes back to virtual graphic as primary graphic
card.

Kristijan Lecnik

gfx_passthru=1 makes the passthru gfx card primary in the VM, 
so you need the additional ATI gfx passthru patch so that the VBIOS passthru works. 

without gfx_passthru=1 the virtual emulated gfx is primary.

does such patch exists?
i am working on this for quite some time now, and didn't came across any
ATI patch, only for nvidia
as i understand that ATI should work out of the box or am i mistaking?

Yes it's available on the xen-devel mailinglist archives, 
and iirc also on the xen vga passthru wiki page.

I think the link/url was already posted to this thread once.

Some ATI cards work as *secondary* without extra patches, 
but passing them as *primary* requires a patch to make the 
ATI specific VBIOS stuff work properly.

Hi Pasi,

I can confirm that their GPU Passthrough works with consumer models, they
visited my college and presented a 30 minute demonstration video where they
acknowledged this.

Wei stated that XenClient ahs a "customized ATI component", and I am quite
certain he is aware our discussion is about consumer models.


XenClient comes with XenDesktop, they market to the on-the-go businessman
so it was designed with laptops in mind, but I am quite sure it would run
on a tower.

Yes, XenClient works with consumer models, like I wrote earlier.
XenServer GPU passthru doesn't.

Note that some/most of those "customized tweaks" to make XenClient work
are not in upstream Xen repositories and also not in XenServer. 
XenClient is a customized product for some specific chipsets/laptops.

XenClient and XenServer have totally different way of working related to graphics passthru stuff.

I wouldn't count on that.. afaik XenClient has pretty limited hardware support/certification.

As far as I know, XenClient AMD GPU passthrough only works on 8 models
of HP laptops. This is because it uses filtered passthrough in which
the dom0 graphics server does some extremely model-specific voodoo
with contexts (presumably involving rewriting of GPU commands to limit
them to a particular region of graphics memory) to share the GPU. Poor
support for AMD GPUs in XenClient is a big part of why I am making my
own desktop Xen/Linux distribution, OpenXCI
<http://sourceforge.net/projects/openxci/>. It will support both
primary and secondary AMD GPU passthrough (rather than XenClient-style
filtered passthrough, it will use conventional passthrough for one
domain and a viewer running on that domain to display all other
domains).

Dear Wei Huang,

How do I use your VGA Passthrough patch with Xen 4.2-unstable?

No, I didn't ask them to include this patch in Xen 4.2. If you have an AMD GPU, you can try it as a secondary passthru without VBIOS patch. Most of them will work from what I heard.

Thanks,

David,

XenServer VGA Passthrough requires a paid/licensed copy, which costs $2500, a bit out of my price range for experimentation.  Important to note that the feature is not a part of the 30-day trial license.

However, Citrix recently visited my college and I was able to preview hardware access on a laptop one of the employees had, where they swapped between Ubuntu and Windows with a hotkey, and various hardware components including onboard GPU and the WebCam were accessible.

In testing XenServer, I can say that if I had a business, that's the product I would use.  In the past month having tried Xen and ESXi, I was astonished with the ease of use for XenServer.

As for Catalyst, version 12.2 (the latest currently) worked for me.

Important to note that until I followed Andrews advice to omit the Catalyst Control Center, the installation resulted in a BSOD.
I saw similar issue whiling playing with XenClient. After discussing with AMD GPU driver team, the conclusion was that the installer has a bug. But I have not received any further update from them. Also manual driver installation (after many tries) did fix problem for me.


The solution, select "Custom" installation and uncheck the CCC.  After the installation your first reboot should run some follow-up updates via cmd, you need to reboot a second time for fully functional drivers.

Also, I had underscan on my monitor so I went out on a limb and re-ran the setup for Catalyst, and was able to get CCC installed with a second run through, which allowed me to fix my underscan issue.

My conclusion is that the CCC requires some driver functionality that isn't available until after you install the drivers, this could be on all systems or it might be related to how HVM's handle the PCI devices, that much I can't say.



Teo,

I could be spouting nonsense, and if so I'm sure Wei can correct me, but I am pretty sure AMD engineers have been contributing to Xen for a while, and some patches have already been applied.  Obviously it isn't flawless, I myself haven't gotten video at boot time, only at the login screen.

This is because VBIOS patch wasn't applied. But as I said before, my VBIOS wasn't universal enough to put it as a production patch. So I am hesitant to put it out.

Dear Wei Huang at AMD Corporation,

Please put your Xen VGA Passthrough patch out so that all of us can have a try.

Thank you very much.
http://old-list-archives.xen.org/archives/html/xen-devel/2010-10/msg00284.html


Dear Wei Huang,

Your VGA Passthrough patch is still not included in the Xen 4.2-unstable tree?

Thank you.

Mine works on 4.1.2, but it is possible that 4.1.0 had less of these "patches" hence Sebastien's post.

Also, I apologize as I did not properly word my opinion before.  VGA Passthrough is new "for consumer components".  In 2010 the number of desktop (not server) boards boasting VT-d functionality could probably be counted on one hand.  To my understanding that means the technology is at most 3 years old, still a baby in my opinion.

I didn't mean that the technology hadn't been implemented into various Hypervisors, just that it is clearly not a perfected feature.  If you consider 3 years of consumer availability, dates become important when researching.  Sebastien's post was May 2011, just shy of one year ago, and Thomas's was in 2010.

There are newer patches still for ATI in Xen 4.2, which I intend to test over the next week.  I have NOT gotten ATI to work at boot time, video starts at the login screen.

I agree with Wei that drivers can contribute to BSOD's and errors, but when an install doesn't fail but the hardware reacts the same as before, I would like to assume the driver is irrelative.

Have you looked at XenClient project? It has a customized ATI component which allows you to switch between VMs flawlessly. I think it is the most mature Xen solution for GPU passthru in client area.

Dear Wei Huang at AMD Corporation,

May I know what is the XenClient project?

Dear Casey DeLorme,

This guy, Sebastien Gauthier, also has the same problems as us. He was using Xen 4.1.0 and an ATI Radeon 4550. He applied Mr. Wei Huang's patch. After installing the latest ATI/AMD Catalyst drivers, he got a BSOD with Xen VGA Passthrough to Windows 7.

Please read Sebastien Gauthier's case here:

http://readlist.com/lists/lists.xensource.com/xen-users/11/59090.html

Hence Sebastien Gauthier reported Xen VGA Passthrough with PARTIAL SUCCESS, like us.

Dear Tobias Geiger,

You were saying that with ATI VGA cards, you do not need to apply any Xen VGA Passthrough patches. But this guy Sebastien Gauthier applied Mr. Wei Huang's patches to Xen 4.1.0 and got a BSOD after installing ATI Catalyst drivers. Sebastien Gauthier did not get 100% success with Xen VGA Passthrough to Windows 7 using an ATI VGA card.
Hi Teo,

The VBIOS patch I sent out did not work for all ATI cards. The patch itself assumed certain behavior of GPU VBIOS. But this doesn't apply to every GPU generation. From this perspective, my patch isn't universal. Also there are many factors, some of which are not in control by us (like graphics driver), can contribute to BSOD you mentioned. I am not in a position to debug it for everyone's card (as I don't have all cards).

Thanks,
-Wei

My mistake for not hitting "Reply to All", sorry.

No worries Casey.



It might be of some value to mention that my tests were with Windows 7, I have no interest in using XP anymore.  Also, I did all of my testing through remote VNC, not once did I actually get video, even 2D, working.

I bought 2 copies of Windows XP Home Edition in the past because it is cheap, at S$145. I did not buy Windows 7 because it is expensive. I got video working all right, but only 2D. I cannot get 3D graphics working.


However, my errors are exactly as you described:

1.  Windows recognizes the model (GTX 460), not "unknown PCI device".
2.  Device code 43.
3.  No resources assigned to the device.

We have the same set of errors.



Might be worth mentioning, I was able to run the latest nVidia driver installation without errors, but after rebooting there was no change, same error code, still no video.

Same situation here with the latest NVIDIA drivers. But I only have 2D video working. I can't get 3D video to work.


 To me this would be evidence that driver version isn't a problem, but then again I didn't have anything actually working.

I agree that driver version isn't a problem. Something is wrong somewhere.




I am an IT student in college, so my experience is limited to mostly programming with very little knowledge of the inner-workings of hardware.  So, forgive me for being unable to help with regards to memory addresses on the cards.

I am hoping that Intel engineers and Xen developers would be able to help.



I've been using *nix for about 4 years, and Windows since I my age was a single digit.  I have had experience setting up server features such as web, database, and application servers but I am still green when it comes to kernel or hardware configuration.

I started learning Linux/UNIX since the year 2005, that is about 7 years ago. I started using Windows when it was version 3.1. I love compiling the latest Linux kernel and assembling my own computer hardware.



My Xen adventure began 35 days ago, and it is no exaggeration to say that in those 35 days I have learned more about linux than I had in the past two years.  I like challenges as much as the next IT person, but I ran out of time and ideas for debugging my nVidia problems.  The nVidia stretch of my adventure lasted for 24 days through 54 fresh linux installations accompanied by over 200~ pages worth of documented failures and not a single pixel sighted.

Why not make your documentation into PDF? It is a very popular document format.



The ATI card took me a day, less than 12 hours of relatively easy debugging by comparison to the aforementioned testing.  I do fully understanding financial constraints, but it is a working solution and worth mentioning.  I do not know what the prices are like in Singapore, but in the states I was able to buy an ATI Radeon HD 6870 for $160.  For me it came down to weighing my objectives against my curiosity.

That ATI Radeon HD 6870 would cost me $279, I think.



If you do continue your nVidia endeavors I wish you success, but as in my former email VGA passthrough is a new frontier, not even Guru's like David may not be able to help beyond their own hardware experiences.

I don't think VGA passthrough is a new frontier. Oracle VirtualBox and Linux KVM supports VGA passthrough as well. Xen ATI VGA Passthrough works out of the box, as Tobias Geiger suggested, but NVIDIA requires patches.




Documentation is one problem I agree with you on 100%.  I came into this knowing relatively little about Linux & hardware, and nothing about Xen, and most every guide I found assumed I had been in a deep relationship with Linux for many years and had a basic understanding of Xen commands.

I started learning Xen since the year 2007, which is about 5 years ago.



Like you, I intend to use those documented failures as well as my recent success to create a comprehensive guide with photographs, screen captures, and perhaps even videos going from "assembled computer" to "Complete Xen Dom0 /w HVM & VGA Passthrough".  Provided the wiki will allow me to upload the screenshots, I'll be certain to post it there.

I will be looking forward to your documentation and videos. Right now Xen wiki allows uploading image files and PDF files. Why not create a PDF document and share it with all of us? It is known as portable document format and is very popular, but it appears that xen mailing lists don't like PDF format.

I don't like wiki pages because anybody can edit and fundamentally mess up the wiki pages, even providing bogus and erroneous information. That's why I don't like creating wiki pages. Anybody can edit and mess up the information you have painstakingly created on the wiki pages. So please take note.

Dearest Casey DeLorme,

Thank you very very much for your kind feedback and input. I would also like to thank Mr. Tobias Geiger, again, for providing his suggestion on exposing the fourth memory region in tools/firmware/hvmloader/acpi/dsdt.asl. In any case, either exposing the first 3 memory regions only or exposing all the 4 memory regions does not work. Sadly, Tobias Geiger is unable to help me further.

I have asked Jean David Techer, what about the 4th PCI memory region? Why only expose the first 3 PCI memory regions? I don't understand, of course. Jean David Techer did not reply to my question.

I have decided to post your prompt reply to the xen-users and xen-devel mailing lists, in case people think that I am finding fault with Jean David Techer, or trying to irritate him, or trying to make him angry, or trying to aggravate him. Jean David Techer replied me with an email saying that I spent too much time and too bent on solving the yellow exclamation mark glitch for my NVIDIA Geforce 8400GS in Device Manager in Windows 8 Consumer Preview and Windows XP Home Edition, and that I sent stupid requests. Stupid requests? Did he read my emails carefully, word by word?

Casey DeLorme, please, can I confirm with you again that you are getting the following errors after applying Jean David Techer's Xen 4.2-unstable VGA Passthrough patches:

(1) Yellow exclamation mark besides your NVIDIA GTX 460 in Device Manager
(2) Windows has stopped this device because it has reported problems. (Code 43)
(3) This device isn't using any resources because it has a problem.

Jean David Techer insists that our technical issues are due to a NVIDIA driver problem. He insists that you have to install NVIDIA driver versions 275.33 WHQL and 275.50 BETA. Any other NVIDIA driver versions (above 280.XX) will not work, according to Jean David Techer. However, I have tried installing NVIDIA driver versions 275.33 and 275.50 from www.softpedia.com<http://www.softpedia.com>, as he suggested, but it caused my Windows XP Home Edition HVM virtual machine to be destroyed/terminated/crash after a few minutes and my dom0 to crash as well. NVIDIA driver versions 275.33 and 275.50 for Windows XP 32-bit is not available from the official NVIDIA website.

So it is definitely not a NVIDIA driver problem. I suspect that the technical issue has to do with MMIO BARs pBAR:vBAR 1:1 matching. I don't think there is any problem with vgabios-pt.bin extracted out from our NVIDIA VGA cards, because I have performed a "hexdump -C" on my extracted VGA BIOS EEPROM, or Electrically Erasable Programmable Read Only Memory.

Secondly, it does seem strange that Jean David Techer was able to attain 100%, ie. perfect success with Xen 4.2-unstable VGA Passthrough to his Windows XP 32-bit and 64-bit HVM domU. Have you watched his Youtube video? It is only 4 minutes. Please do watch Jean David Techer's Youtube video at the following URL:

Jean David Techer's Xen 4.2-unstable VGA Passthrough to Windows XP x64 HVM domU Youtube video link: http://www.youtube.com/watch?v=3SaYO0ERW44

I am appalled and baffled that he has attained 100% success while both of us have only attained partial success (i.e. less than 100%) on Xen 4.2-unstable VGA Passthrough to Windows 8 Consumer Preview and Windows XP.

Solving the yellow exclamation mark issue is important because we would not be able to run 3D graphics benchmarks and play 3D games without solving it. I am not sending silly emails about some yellow marks, as Jean David Techer suggested. I can't even run Unigine Heaven DX11, and 3dmark11 3D display benchmarks, because of the yellow exclamation mark for NVIDIA Geforce 8400 GS in Device Manager.

Casey DeLorme, with your report on relatively easy success with ATI VGA cards, I think I would go the ATI way, but I would have to spend a few hundred dollars compared to my cheap SGD$44 NVIDIA Geforce 8400 GS card. And while deciding to go the ATI way, I would also like to continue troubleshooting with the NVIDIA problem, because I consider it to be a technical challenge.

In essence, Jean David Techner is considered to be a "boss", or business owner, or proprietor, or technopreneur, or entrepreneur, or technical support officer, or customer support officer, or IT helpdesk engineer, providing services like his forward-ported Xen 4.2-unstable VGA Passthrough patches and the documentation on his blog. I repost Jean David Techer's official website here:

Jean David Techer's Xen 4.2-unstable VGA Passthrough blog: http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through

Jean David Techer's official website is his business venture.

Basically, I am Jean David Techer's "customer", trying to obtain technical support from him. Of course, he is not obliged to provide technical support to me since he is providing free services. It is, after all, an open source software project. Nobody is obliged to provide anybody with technical support. To do Jean David Techer justice, he replied most of my questions while avoiding some of my questions.

Finally, I have also failed to obtain technical support from Xen developers like Ian Campbell from Citrix Corporation and Konrad Wilk from Oracle Corporation. I have always provided all the steps which I have taken, the configuration files and necessary documentation, and kernel messages and error logs to xen-users and xen-devel mailing lists, but they keep insisting I did not provide the information they required. I wondered why. I think they did not read my emails carefully. They told me they would not reply to me any more if I do not provide the information they requested. But the problem is that I have always provided information they requested! I think they missed some of my emails, or did not read my emails carefully enough. I am an ardent supporter and SERIOUS software tester for open source Xen virtualization/hypervisor but they treated me lightly. I always read my emails WORD BY WORD. I have even went to the point of making a video on the BUG and uploading my video to Youtube. The video is only THREE minutes.

As everybody says, a picture is worth a thousand words. A video is worth a BILLION words!

I have also failed to obtain technical support from Xen developers regarding Xen 4.2-unstable VGA Passthrough.

I am hoping Xen 4.2 would have official support for Xen VGA Passthrough for both NVIDIA and ATI cards.

Casey DeLorme, thank you very much once again. I will be making changes to my Xen, Linux Kernel and Xen VGA Passthrough Documentation and will be releasing Version 1.7 shortly. Jean David Techer's documentation assumes some level of advanced Linux technical knowledge, so I am writing documentation on my own so that everybody, not just advanced Linux and Xen users, can follow. I have made references to Jean David Techer's documentation in my own documentation.

I would be very happy if people would use my documentation. Of course, it satisfies my ego and my vanity. Haha.

I have been un-employed for nearly three years now, and I would hesitate to spend a few hundred dollars on an ATI VGA card. I quit my job as an IT engineer 3 years ago because my father suffered from lacunar infarct, or more commonly known as stroke. My NVIDIA Geforce 8400 GS costs only S$44. Please understand why I hesitate to buy an ATI VGA card. The cheapest one costs SGD$279.

I have a diploma in Mechanical+Electronics engineering from Singapore Polytechnic and a Bachelor's degree in Mechanical Engineering from the National University of Singapore. But I do not have qualifications in Computer Science or Information Technology. I have worked as an Information Technology engineer in Defense Science and Technology Agency, Ministry of Defense, Singapore, National Computer Systems Pte Ltd, Asiasoft Online Pte Ltd, and Ishinemax Singapore Pte Ltd.

You sound plenty competent, but it's important to remember that you are pioneering a technology that for consumers is still in its infancy.  Very few people are testing this with consumer equipment, so finding results seems to be a rarity.
