[Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Platform : Nehalem, official Intel x58 with Core i7 920 (dx58so)
Main (Console): Nvidia 9500 GT PCI Express
Secondary: Nvidia 8800 GTS PCI Express

Yes, I binned the ASUS P6T due to bad VT-d support in the BIOS.

With the latest BIOS from Intel, the dx58so has enable/disable for VT-d, ICH FLR
and Interrupt Mapping! Helped a lot with getting this working ...

Dom0: 2.6.18-xen0 (built from xen-3.4-rc1)
DomU: 2.6.26-1-xen-amd64 (deb lenny shipped)

SUCCESS! - Linux DomU with the official drivers from Nvidia (180.44) .. boot
DomU into console, patch and install Nvidia driver, then started X using
defaults. gdm chooser appeared on Secondary screen!!

So far, i`m using VNC or Synergy to control the DomU (from Dom0 also running
X/gdm) and it is good and stable.

ISSUES:
This is only possible after a clean restart of the physical machine. Dom0 kernel
seems to have problems with the IRQ. BUG trap: "irq has gone away"
after attempting to start DomU a second time, Dom0 kernel displays: Disabling
IRQ#. (the IRQ IS being shared on Dom0 with a usb controller, but im assuming
this is already patched from reading xen history)

Also confirmed that this is NOT possible under a HVM or running Windows in a
DomU, this could be due to the IRQ corruption but i`m not really sure, in both
cases the PCI device is visible but the driver will not load :(

As these vga cards dont support FLR, would the FLR code when attempting d3r or
sbr cause the interrupt corruption ?

Some steer and some assistance would help here, i`m trying to get this working
for HVM too !?

BTW: I`m eagerly awaiting Jeremy Fitzhardinge to bring pciback.ko to the modern
kernels ! Support for this chipset in 2.6.18 is not very good and i would like
to try pvops and PCI passthrough. (although, got a hang with x2apic and IRQ
mapping enabled)

I`m willing to help move the development of xen forwards with any testing or
assistance you guys need!

Thanks,
Tim

Hi Tim :

I heard the good news you published from Xen Maillist.That really
inspired me. Recently i was working on vt-d graphic passthrough experiment.
That was a real tough job for me. I faced some problems that you may also
met before. So i hope you can give me any advises or informaitons.
Any reply appreciated!

HardWare: Q35 matherboard + PCIE NVIDIA 9400 + PCI ATI R128 + IGD Intel
Two Monitors connected with respective cards
OS : Domain0 (Gentoo X86_64 2.6.28)
DomainU (Ubuntu i386 / windows xp / RedHat Ent4.5)
Xen3.3.1

At first ,I assumed the Matherboard integrated graphic card for Domain0 then
passthrough the PCIE NVIDIA graphic card for DomainU.
But My Matherboard cann''t support those two cards work together.
And Everytime i use the PCIE card render for Domain0, the VT-D can''t
be
Enable Because of the RMMR incorrect.
Considered that reason , the PCIE card was aborted in my experiment.
Now I use the integrated card as the primary card ,the ATI PCI graphic card
as the secondly.
Now i face the problem is that the DomainU asigned the ATI card can''t
displaied on the Monitor connected with the ATI card.
>From you information on Xen maillist,you passthrough the PCIE NVIDIA card to DomainU --> boot from console -->
setup the proper driver for that card --> startx --> then the DomainU
display on the second Monitor
Any other works ?
Is that right? You didn''t change any source codes. The whole process
are
works about configurations.
I tried install a R128 driver in DomainU for the ATI card and Modified the
xorg.conf(/etc/X11/xorg.conf) to tell the DomainU use the ATI card do render
work.
whatever i do the DomainU always stay on the same screen.

Now i have none idea for the next step .
Hope you can give me some help.

Thanks so much !

Re: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Working on something similar. Have you contacted Peter J. van der Maas
regarding this? He has the Q35 intel board, but was able to fully pass
through an nvidia card to a Windows HVM DomU. You can see his latest message
on Thu, Apr 9, 2009 at 5:54 PM in the xen-users list. He may have some more
technical details regarding this, but he seems hesitant to provide more
details to these lists.

RE: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Hi Bryan

I think my email to Peter along with emails from probably yourself and other
people in the community is what prompted his reply to xen-users.

There seems to be a general reluctance to move this forwards within the Xen
developers, I think this may be due to the current status of some of the
commercial vendors that are working on the "next big thing" for
Virtualisation. Neocleus and XCI seem to be the products that will bring this to
market.. it seems that the open source community may be being left out at this
stage!?

Tim

Come on, XCI sources are fully open source and available on the web!

The plain truth is that graphic card passtrough doesn''t always work at
the moment, most of the problems come from the rexecution of the vga
bios (or the lack of thereof).
You can read the workaround we have in place in XCI in
tools/libxc/xc_hvm_build.c:setup_vga_pt, but even that one doesn''t work
all the times.

RE: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Hi Stefano,

Thanks for your reply. This is the first time that I have been provided with
some pointers where to look.. like I said in previous emails, I can work on this
but I didn''t write Xen or any of these workarounds!

I also posted the [attached] question about XCI - no one answers :(

Can you help answer?

Thank you again,
Tim

I`m assumingalos, that Citrix Project "Independence" is simply a name
for XCI?

Are there more than three main gfx vendors? ;-)

The passthru has been got working on at least one example of each of ATI,
nVidia and Intel integrated gfx. That doesn''t necessarily mean it will
work
for your chip, with your BIOS. Getting it working can on some systems be
quite a pain in the arse, even if a developer has local access to the
system.

The VGA support in XCI at the moment is Intel specific.

However videocard passthrough should work OK with most graphic cards if
you passthrought the videocard to the guest as a secondary card (you do
not disable the emulated cirrus vga). The problem with this approach is
that you are not able to see anything on the screen until the guest
enables the secondary card so you may need to configure the guest using
vnc fron another machine, at least the first time.
On the other hand if you disable the emulated vga so the pt graphic card
happers as a primary in the guest, you should be able to see output on
the screen since the beginning of the guest boot sequence, but then you
are going to have more vga bios problems.

RE: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Kier,

I have an nvidia nv4 (8800 GTS) and 9500 GT and they do not work under XCI (as
primary or secondary cards) and the same problem under xen-rc1. I have also
tried ATI cards to no avail.

Will it be possible to get a list of bios + vendors /drivers that have been
tested / compatible? I will even offer to maintain the Wiki with such
information!!

Cheers,
Tim

RE: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Thanks Stefano,

I have tried all your suggestions with both XCI and Xen-rc1 already to no avail.
It works for pv DomU but not HVM.

Disable/enable Cirrus - no effect, tried -std-vga -vga none and all host of
combinations. When trying primary, the DomU seems to fail and qemu just quits I
think due to no video.

Can I get some dmesg / logs that will help to analyse further?

As I just mentioned to Kier, I''m more than willing to help the
community out with this one ;) I have been writing code for Win32 for years, i`m
just a bit new to the Xen scene and developing towards the hw.

Cheers,
Tim

Re: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Hi Tim,

Here is the current status for the different vendors.

Nvidia graphic cards don''t work as primaries, there are some issue
with the bios rexecution.
Nvidia cards should work as a seconday display adapter side by side
with the cirrus.

So far ATI doesn''t support vt-d.

Intel graphic card only works as a primary.

In this case you are interested in the qemu and xen logs.
For qemu, just open /var/log/xen/qemu-dm-guestname.log; for xen
compile the hypervisor with debug = y (in Config.mk) and keep an eye on
the serial.

[Xen-devel] RE: [XCI] result of pci vga passthrough

Hi Stefano,

Please find attached, logs from XCI and a quick jpg of the WinXP host.

I will compile Xen for XCI with debug if necessary?

Cheers,
Tim

Could you explain why you use XCI for this kind of thing (video
passthrough)? Because it provides better support?

RE: [Xen-devel] RE: [XCI] result of pci vga passthrough

XCI is supposed to provide more rounded support as it seems that most
development of vendor workarounds are in XCI.

Not official answer, maybe Xen developers can give a better steer?

Re: [Xen-devel] RE: [XCI] result of pci vga passthrough

Hi,

XCI support pass through as a primary display adpater, the patch are
not into xen unstable.
For nvidia graphic card as a seconday it shouldn''t make any different
because nvidia only works as secondary.

Does that mean we use only 1 video card (primary), and use it for
DomU? Then Dom0 has no video card?

I mean pass through as a primary in the guest, for doing so we have to:
  - Rexecute the bios
  - Map the legacy iomem
  - Map the legacy ioport

dom0 could have a graphic card be it''s not required.

So we can have 2 cards, and pass one to DomU, and DomU sees that as
primary video card?

I searched around, but dont see where to download XCI??

Yes, that the tricks to make it works with intel graphic card, but I
thing it won''t change anything for nvidia or ati card.

http://xenbits.xen.org/xenclient/

clone build.git and then there is a readme inside.
Don''t hesitate if you have any further questions.

Jean

You have some stuff in the qemu logs I am not familiar with.
Where do all the:

XenPCI --> XenPciPdo_EvtDeviceWdmIrpPreprocess_START_DEVICE

and

XenNet --> XenNet_ConnectBackend

come from?

[Xen-devel] RE: [XCI] result of pci vga passthrough

Stefano / Jean,

I am looking through these logs and nothing seems to be wrong ! no error mapping
i/o or mem for Xen or Qemu, for all intents and purpose this should work? I feel
like i`m cracking up!

Additional info attached.

What IS strange is that the card is detected as PCIe V1.0 not V2.0 which it is.
When using pv DomU this does show as a PCIe v2.0 card ... but not under HVM.

Cheers,
Tim

For qemu, just open /var/log/xen/qemu-dm-guestname.log; for xen
compile the hypervisor with debug = y (in Config.mk) and keep an eye on
the serial.

I have tried pass through a PCI ATI graphic card to DomainU.
I recognized that the ATI would be the second card.
I boot the DomainU with console and modified the xorg.conf file for the
X-window rendered by the ATI card.
But the DomainU still displaied on the same screen.

I want to know how to make the DomainU displaied on the second screen?
How to disable the emulated graphic card.

[Xen-devel] RE: [XCI] result of pci vga passthrough

I think this is coming from the GplPv drivers, we have 0.10.50 installed at the
moment ... is there a specific version that you have tested with XCI. I
don''t think this matters for PCI passthrough ?!
Also used older versions of GplPv too and also tried without ...

Thanks,
Tim

RE: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Hello Wei,

Please try with your Nvidia card, ATI not working with VT-d.

You WILL have to compile from source, to fix bad RMRR error. This will make VT-d
work.

Then hope your BIOS isn’t too broken and try again.

Tim

And Everytime i use the PCIE card render for Domain0, the VT-D can''t be
Enable Because of the RMMR incorrect.

See:
http://www.nabble.com/Re:-Re:-VT-D-RMRR-is-incorrect-p22022061.html

Use this work around and (/* the whole “if” section */) and compile Xen.

The VGA support in XCI at the moment is Intel specific.

However videocard passthrough should work OK with most graphic cards if
you passthrought the videocard to the guest as a secondary card (you do
not disable the emulated cirrus vga). The problem with this approach is
that you are not able to see anything on the screen until the guest
enables the secondary card so you may need to configure the guest using
vnc fron another machine, at least the first time.
On the other hand if you disable the emulated vga so the pt graphic card
happers as a primary in the guest, you should be able to see output on
the screen since the beginning of the guest boot sequence, but then you
are going to have more vga bios problems.

I have tried pass through a PCI ATI graphic card to DomainU.
I recognized that the ATI would be the second card.
I boot the DomainU with console and modified the xorg.conf file for the X-window
rendered by the ATI card.
But the DomainU still displaied on the same screen.

I want to know how to make the DomainU displaied on the second screen?
How to disable the emulated graphic card.

Re: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Thanks so much for your reply.
Because of the RMRR incorrect , i aborted the NVIDIA card.
I will use the ATI card as the primary the NVIDIA card asigned to GuestOS.
Hope some good news !

We''ve had a HD3450 mobile ATI card working as secondary in a vista VM
with std drivers -- it just required a secondary bus reset. There was a bug at
one point where various bridge flags weren''t preserved across a reset.

Re: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Hi Tim:

  I have modified the source code and recompiled. Everything seems good .
Without RMRR incorrect and VT-D enable.

   Domain0 works with VT-D.

   DomainU asigned the PCIE NVIDIA card

   installed the nvidia-177-83 drivers for DomainU .

   But I am still face the tough question mentioned before that DomainU
cann''t be   displaied on the second screen.

    Booted the DomainU with console --> configured the driver for card -->
startx

     DomainU staied on the same screen then went into  black screen but
still alived.

Any hint was appreciated.

Thanks so much

Re: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Hi Tim :
      I am still working about VT-D Graphic pass through experiment. Even
with your guys'' useful helps, I still cann''t make the DomainU
displaied on
the second screen connected with the graphic card passed through.
      You said you used the "DomU: 2.6.26-1-xen-amd64 (deb lenny
shipped)" as
DomainU. you also said that " Also confirmed that this is NOT possible
under
a HVM or running Windows in a DomU, ".

      That means the DomainU should be Para-Virtualization in your
experiment of VT-D graphic pass through .
      How do i get the 2.6.26-1-xen-amd64 (deb lenny shipped) DomainU for
testing?

Thanks

Wei

RE: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Hi Wei,

Yes, DomU should be PV.

Any Xen-enabled kernel will be OK for DomU.

Do you have pciback=”” kernel cmdline for Dom0.

What does lspci -vvv show for the DomU ?

Please also include your X server log file for DomU and your Dom0 Kernel output.

Ta

Tim

Re: [Xen-devel] good progress on pci vga passthrough in xen-3.4-rc1

Hi Tim :
    I didn''t pay attention to the PV DomainU. I always use the HVM or
Windows OS as the DomainU in my experiments. You remaid me  the PV GuestOS
may make that work easily.
But i still have some questions :
    The PV DomU supported the VT-D / IO virtualization ?
     Did i add the command line "pci = [''xx:xx.x'']"
in config file of PV
DomU ?

For you questions :

Do you have pciback=”” kernel cmdline for Dom0.


yes , I added  " pciback.hide = (xx:xx.x) " cmdline in " module
................"

I also added the "iommu = 1 vtd = 1" in " kernel
....................... "


What does lspci –vvv show for the DomU ?



using the lspci -vvv cmd, i could find the NVIDIA card passed through in
DomU HVM.

But i can''t use that for rendering X-window .


Please also include your X server log file for DomU and your Dom0 Kernel
output.
Presently , My system doesn''t work . I will attach those files next
time.

Thanks so much .
