Re: [Xen-users] Re: Successful PCIe Graphics VT-d Passthrough to Win32 DomU, Q35 chipset

[Alexia Benington]

Hi,

I've tried going through Xen-unstable (as of Changeset 19400), and I
believe that the necessary code to make VGA passthrough work correctly
has not been incorporated into Xen-unstable yet.

The closest that I ever got was that DomU can detect the VGA card. I
had to disable the Cirrus or Std VGA bios loaded by hvmloader. But
DomU still can't make use of the card properly. For Windows, it shows
Error Code 10 in Device Manager. I was also expecting video output on
the monitor connected to the passed through card. However, that wasn't
the case.

Nvidia 9500GT Xen VGA passthru

[Pasi Kärkkäinen]

Hello Peter,

Some people have been asking for tips about Nvidia Xen VGA passthru,
so maybe you could help? 

Could you post the exact steps you did? 

Have you tried with Xen 4.0.x after your initial experiments in 2009? 

Thanks!

RE: Nvidia 9500GT Xen VGA passthru

[Peter van der Maas]

I really have not played with too much after the proof of concept.  I do recall something eventually breaking the config, perhaps a Xen update.  I've since put the hardware to better use, although I am still intrigued by Xen.  At the time, I was working with a team that was giving serious consideration to virtualizing their platform, and what better way to learn than dig in and get my hands dirty.

I tried to include as much detail at the time, with the plethora of different Xen builds, BIOS's updates, etc.

If someone has something specific I can try to help, but doubtful I will be of any use.  For example, I did not realize Xen 4.x was even released.  Recent projects I've been working on do not lend themselves well to virtualization; however, I might have to give Xen 4.0 shot - just to play, of course.  There were some serious changes happening with Xen, the Linux kernel, and KVM when I stopped playing. 

Sorry I could not be of more help.

Ok.

I mainly meant if you remember what custom patches did you have to use/create? 
Most probably you had to do some vBar=pBar hacking, right? 

I guess I'll have to try this myself one day and document the process
with current Xen versions..

Re: Nvidia 9500GT Xen VGA passthru

[Anish Patel]

I have this almost working now,   I think the only thing that i need to 
change is to add a gfx_passthru=2 option to let xen know not to read 
from /dev/mem then an option to tell it what VGA rom to use.   Are there 
any patches for 4.01 for this?


Thanks
Anish

I think gfx_passthru can only use 0 or 1 nowadays.

Patches probably need to be forward-ported to current Xen.. 
most of them are for xen-unstable from the Xen 3.5 days..

Re: Nvidia 9500GT Xen VGA passthru

Hi All,
     I have managed to get the 2nd vga passed though.  I had to use 
AMD/ATI card to get this done.


Thanks

Nice!

Please post the details:

- VGA card model
- Xen version
- Dom0 kernel version
- DomU OS/version/kernel
- Any custom/additional patches used

Re: Re: Nvidia 9500GT Xen VGA passthru

[Sander Eikelenboom]

Hello Anish,

Could you post some information about your setup, so others can benefit from it ?

- dom0 kernel version / config ?
- Xen hypervisor version ?
- domU OS and graphics driver version ?
- domU config file ?

- Additional patches applied to xen ?

- Brand/model primary graphics card ?
- Brand/model secondary graphics card ?
- Intel (vt-d) or AMD (iommu) platform ?

I have done some attempts my self, but only succeeded to get vga safe mode in windows XP so far.

Re: Nvidia 9500GT Xen VGA passthru

[Anish Patel]

Hi All,
     I will post the full patch set soon there are still a couple of 
bugs i need to work out.

System -
Phenom x6 2.8
16 gig DDR3
BIOSTAR 890FX board with latest bios.
Dom 0 config
     4 cores, ATI 5450 with open source drivers.

Dom U
  WinXP HVM, 5770 passed through to Dom, 2 cores, 2 gigs memory.

Please give me a couple days and i will post a full write up

I can probably get this to work with the nvidia card as well, but need 
to figure out the pBAR/vBAR stuffs.

Thanks
Anish

RE: Nvidia 9500GT Xen VGA passthru

[Peter van der Maas]

Congrats to all that got it working!  

For a while, I thought it must have been a miracle or some other divine intervention as it was taking me so long.  Glad to see others making progress, though I must say I am surprised that Xen, Intel, etc. have not made this easier since I worked on this last over 2 years ago.

For the rest, hang in there and keep at it!  You will get it!

-Peter

Re: [Xen-devel] Re: Nvidia 9500GT Xen VGA passthru

[Tobias Geiger]

Hi,

its running here with

(XEN) Xen version 4.1-unstable 
(XEN) Latest ChangeSet: Fri May 07 19:22:28 2010 +0100 21331:bbf009817ffb

rather old, but xen4 .
http://lists.xensource.com/archives/html/xen-devel/2010-05/msg00441.html
contains all i applied to get it working (03_dsdt contains the vBAR/pBAR 1:1 
Mapping)

Hardware is 
Corei7 CPU on Intel DX58SO 

Passed-through-GFX is
03:00.0 VGA compatible controller: nVidia Corporation GT200 [GeForce GTX 260] 
(rev a1)

GFX for Dom0 is:
02:00.0 VGA compatible controller: nVidia Corporation G96 [GeForce 9500 GT] 
(rev a1)
Dom0 Kernel: 2.6.34.7 from http://code.google.com/p/gentoo-xen-kernel/

its working flawless with winxp (but i can only boot the domU once, shuting it 
down and recreating it, makes domu AND dom0 hang... i can live with that 
limitation for now)
whats not working is windows7 or vista; can't figure out why 

Greetings
Tobias

I recall this being a problem for me, too, using the Win XP DomU way back when.

Just curious, has Citrix solved this on the commercial side?

I think Citrix XenServer only supports VGA passthru of
"virtualization friendly" cards that are designed for VGA passthru
(eg. some nvidia quadro "multi-OS" models)

Re: [Xen-devel] Re: Nvidia 9500GT Xen VGA passthru

[Anish Patel]

Hi All,
     Have any of you guys run any 3d benchmarks on your systems?
I have a ~7605 in 3dmark 2k6 with my ATI 5770 (eng sample), 3GB RAM, and 
2 cores of my AMD x6 2.8 1055T assigned to the XP vm.

Thanks
Anish
