Hi Teo, I don''t get this message; my VGA (Nvidia Geforce GTX260) does not have the exclamation and the driver load successfully. Have you tried with the extra patch for secondary cycles as I mentioned before? Please look again at my implementation of the patches and try to replicate. BTW, I watched your Videos!

Hi Tim, Yes, I had applied the last and final secondary-gfx-patch to xen 3.5-unstable changeset 20143 but the result is still the same. I cannot solve the "not enough free resources" problem. I am using the latest Intel ACPI CA compiler version 20090730. Wonder if this has any impact. Also I am using xen with pvops dom 0 kernel 2.6.31-rc6.

RE: [Xen-devel] Video Presentation on PCI Express x16 VGA Pass Through to Xen-based Windows XP Home Edition HVM Virtual Machine
Hi All,
I went through the history and here are the steps I took to patch xen
3.5-unstable for VGA passthrough.
Based on Weidong''s advice I checked out changeset earlier than 20144.
Initial trial without secondary gfx passthrough patch
================================
637 hg clone http://xenbits.xensource.com/xen-unstable.hg
638 cd xen-unstable.hg
639 vi tools/firmware/hvmloader/hvmloader.c
640 hg checkout 20143
641 cp
~enming/intel-gfx-passthru-patches/intel-gfx-passthru-patch01.patch .
642 patch -p1 < intel-gfx-passthru-patch01.patch
643 make tools
644 history
645 cd tools/ioemu-remote/
646 cp
~enming/intel-gfx-passthru-patches/intel-gfx-passthru-patch02.patch .
647 patch -p1 < intel-gfx-passthru-patch02.patch
648 cd ..
649 cd ..
650 cp ~enming/intel-gfx-passthru-patches/xen-load-vbios-file.patch .
651 patch -p1 < xen-load-vbios-file.patch
652 cp ~enming/intel-gfx-passthru-patches/xen-vBAR-pBAR.patch .
653 patch -p1 < xen-vBAR-pBAR.patch
654 cd tools/ioemu-remote/
655 cp
~enming/intel-gfx-passthru-patches/qemu-change-for-vBAR-pBAR.patch .
656 patch -p1 < qemu-change-for-vBAR-pBAR.patch
657 cd ../../
658 make clean
659 cp ~enming/vgabios-pt.bin tools/firmware/vgabios/
660 ls tools/firmware/vgabios/vgabios-pt.bin
661 make xen
662 make install-xen
663 make tools
664 make install-tools
In the above case, intel-gfx-passthru-patch01.patch is actually
xen-gfx-passthrough.patch as posted by Weidong.
intel-gfx-passthru-patch02.patch is actually qemu-gfx-passthrough.patch
as posted by Weidong.
After building and installing everything, I rebooted. When I tried to
passthrough the nVidia Geforce 8400 GS, I got "not enough free
resources" in Windows XP domU. This is in fact much better than my
earlier trial when I got "device cannot start" in Windows XP domU
device
manager with the wrong approach of using onboard gma4500 graphics as
primary and nvidia geforce 8400 gs as secondary. This time I am using
nvidia geforce 8400 gs as the primary and nothing else as the secondary.
After Timothy Moore''s suggestion, I proceeded to the next trial.
Next trial WITH secondary gfx passthrough patch
=============================
679 cd /usr/src
680 mv xen-unstable.hg xen-unstable.hg-20143-no-secondary-patch
681 cp -R xen-unstable.hg-20143-no-secondary-patch xen-unstable.hg
682 cd xen-unstable.hg
683 history
684 cd tools/ioemu-remote/
685 cp
~enming/intel-gfx-passthru-patches/qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch
.
686 patch -p1 <
qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch
687 cd ../..
688 make clean
689 cp ~enming/vgabios-pt.bin tools/firmware/vgabios/
690 ls tools/firmware/vgabios/vgabios-pt.bin
691 make xen
692 make install-xen
693 make tools
694 make install-tools
At this point, I encountered an error with build.c as documented with my
earlier postings in xen-devel mailing list.
So I applied my very own patch:

Then I checked ssdt_pm.h and ssdt_tpm.h to make sure they are correct.
695 vi tools/firmware/hvmloader/acpi/ssdt_pm.h
696 vi tools/firmware/hvmloader/acpi/ssdt_tpm.h
697 make install-tools
But I still get "not enough free resources" in Win XP domU device
manager. So apparently
the patch qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch
doesn''t affect my nvidia geforce 8400 gs passed through operations
since
I am using nvidia as primary and nothing as secondary. The secondary gfx
patch is for cases when you have a primary for dom0 and passing through
the secondary gfx to a HVM domU.

I found I still cannot watch your video, even cannot access youtube. The output of ''xm dmesg'' means it really 1:1 maps for vBAR and pBAR. It should be no problem. Can you post qemu log (/var/log/xen/qemu-dm-xxx.log)? You below steps look correct. But I didn''t encounter the error with build.c. Tim, did you encounter the error?

Did you verify (and modify if applicable) the PCI resources as per Weidong''s comment here? http://permalink.gmane.org/gmane.comp.emulators.xen.devel/70749 On another topic, please don''t answer to other threads to get attention and keep threading working by replying to previous versions of your own post or its replies (and and least for me, don''t reply to my personal mail address but just to the mailing-list) Best regards, Christian Mr. Teo En Ming (Zhang Enming) wrote:> Hi All, > > I went through the history and here are the steps I took to patch xen > 3.5-unstable for VGA passthrough. > > Based on Weidong''s advice I checked out changeset earlier than 20144.[...] _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Dear Christian,>Did you verify (and modify if applicable) the PCI resources as perWeidong''s comment here? http://permalink.gmane.org/gmane.comp.emulators.xen.devel/70749 Thanks for the tip! I missed this one. I believe it should solve the "not enough free resources" problem for my graphics card. Weidong and me are using different nvidia graphics card. Hence I should modify the dsdt.asl MMIO BARs entries in xen-vBAR-pBAR.patch to reflect my graphics card.>On another topic, please don''t answer to other threads to get attention andkeep threading working by replying to previous versions of your own post or its replies (and and least for me, don''t reply to my personal mail address but just to the mailing-list) Sorry!

Hi All,
I have solved the final problem.
Thank you Christian Tramnitz for pointing me to the missing link.
I have tested my own modifications to xen-vBAR-pBAR.patch and it works!
I reproduce part of xen-vBAR-pBAR.patch here which I modified for my nVidia

RE: [Xen-devel] Video Presentation on PCI Express x16 VGA Pass Through to Xen-based Windows XP Home Edition HVM Virtual Machine
Dear All, Here is my latest video presentation on VGA passthrough. Please check out my blog at http://teo-en-ming-aka-zhang-enming.blogspot.com/ or the Youtube link at http://www.youtube.com/watch?v=1ia3IwG6tp4 The "not enough free resources" problem for nVidia Geforce 8400 GS PCI Express x16 graphics card in earlier presentation videos: http://www.youtube.com/watch?v=HNEiSI...<http://www.youtube.com/watch?v=HNEiSInrav0> http://www.youtube.com/watch?v=_hOT_9...<http://www.youtube.com/watch?v=_hOT_9LIG5w> was fixed. Device manager in Windows XP HVM domU no longer shows an exclamation mark besides the nVidia Geforce 8400 GS graphics card. The device is working properly and the resources tab shows the available memory ranges. Full VGA passthrough to Windows XP HVM guest operating system using Xen virtualization has been realized. I am now able to run 3-D video benchmarks on the passed through nVidia GeForce 8400 GS graphics card. All this is possible using Xen 3.5 hypervisor with Intel supplied VGA passthrough patches. Instead of using pvops dom0 kernel 2.6.31-rc6 which causes Win XP domU to run slowly, I am now using pvops dom0 kernel 2.6.30-rc3. Many thanks to Xen developers, Han Weidong and other engineers at Intel, and also Christian Tramnitz for pointing me to the missing puzzle which helped me in resolving the final problem. I am now able to bootstrap Windows XP HVM domU from within Linux using Xen virtualization and play 3D games in the Windows virtual machine. In the past, Windows virtual machines can only see a 2D emulated/virtual display adapter. The virtualized Windows operating systems were more palatable to server administrators than gamers. With VGA pass through and direct hardware access by Windows virtual machines to the graphics hardware, gamers will now be able to play 3D games inside Windows virtual machines. PS: I am still unable to passthrough USB devices, e.g. keyboard and mouse, to the Windows XP HVM domU. This video is captured and rendered using the open source kdenlive non-linear video editor. The video is taken using Canon HV20. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore Blog URL: http://teo-en-ming-aka-zhang-enming.blogspot.com Email: space.time.universe@gmail.com MSN: teoenming@hotmail.com Mobile Phone: +65-9648-9798 Street: Bedok Reservoir Road Republic of Singapore _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, I will try to stop unnecessary services on Dom 0 and do a disk I/O benchmark between WinXP domU on 2.6.30-rc3 and 2.6.31-rc6 tonight (Singapore time). That will be more conclusive. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore Blog URL: http://teo-en-ming-aka-zhang-enming.blogspot.com Email: space.time.universe@gmail.com MSN: teoenming@hotmail.com Mobile Phone: +65-9648-9798 Street: Bedok Reservoir Road Republic of Singapore On Fri, Sep 11, 2009 at 2:17 AM, Jeremy Fitzhardinge <jeremy@goop.org>wrote:> On 09/10/09 07:03, Pasi Kärkkäinen wrote: > > On Thu, Sep 10, 2009 at 08:28:03PM +0800, Mr. Teo En Ming (Zhang Enming) > wrote: > > > >> Dear All, > >> > >> Here is my latest video presentation on VGA passthrough.

Re: [Xen-devel] Video Presentation on PCI Express x16 VGA Pass Through to Xen-based Windows XP Home Edition HVM Virtual Machine
Dear Pasi, Yes, I have tried the nomodeset kernel parameter without result. I couldn''t get Jeremy''s rebase/master branch (pvops dom 0 kernel 2.6.31) to work despite disabling all of USB support in the kernel. I will troubleshoot this issue with the serial console enabled another time. Meanwhile, I got Linus'' mainline kernel 2.6.31 to work on my system. So apparently the dom 0 patched kernel 2.6.31 has some issues or I did not configure it properly. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore Blog URL: http://teo-en-ming-aka-zhang-enming.blogspot.com Email: space.time.universe@gmail.com MSN: teoenming@hotmail.com Mobile Phone: +65-9648-9798 Street: Bedok Reservoir Road Republic of Singapore On Sun, Sep 13, 2009 at 5:12 PM, Pasi Kärkkäinen <pasik@iki.fi> wrote:> On Sun, Sep 13, 2009 at 08:31:26AM +0800, Mr. Teo En Ming (Zhang Enming) > wrote: > > I have disabled all USB support in the kernel but I still couldn''t get > pvops > > dom0-patched kernel 2.6.31 final to complete loading.

Re: [Xen-devel] Video Presentation on PCI Express x16 VGA Pass Through to Xen-based Windows XP Home Edition HVM Virtual Machine
USB Device Pass Through Succeeded How thick I must have been! In my earlier blog posts with VGA passthrough succeeded, I said that I couldn''t passthrough any USB device at all. As a matter of fact, Timothy had corrected my usbdevice directive in the guest config file in an earlier mailing list post but I didn''t take a careful look at the usbdevice directive at all. The correct usbdevice directive is: usbdevice = "host:vendorid:productid" I had used usbdevice = [ ''host:vendorid:productid'' ] which is completely erroneous. I need to omit the square brackets for USB device passthrough to work. I have now successfully passed through the USB optical mouse to the Windows XP Home HVM domU and using on-screen keyboard as a substitute for the physical USB keyboard. The reason I am doing this is because QEMU with Xen can only allow one USB device to be passed through at any one time. It was so obvious and I missed the obvious!

Dear Pasi, No, I have not tried it yet. I have 8 GB of memory on my computer. What does dom0_mem parameter do?

It limits the memory dom0 will have. The rest of the memory is available for other virtual machines (ie. "xm info" lists it as free memory). If you don''t limit dom0 memory then every time you create a guest dom0 memory needs to be ballooned down to be able to give it to the new guest. So it''s better to always have dom0_mem specified, so that dom0 kernel settings don''t get confused when it gets ballooned much more down than what it had available at boot time. Example grub.conf entry: kernel /boot/xen-3.4.gz dom0_mem=1024M This allocates 1024 MB of memory for dom0, and the rest is free for other domains to use. There is a bug in the recent pv_ops dom0 kernel that causes problems if dom0 has >4096 MB of memory. So please try to limit your dom0 memory, it might fix the USB problems. -- Pasi> -- > Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical > Engineering) > Alma Maters: > (1) Singapore Polytechnic > (2) National University of Singapore > Blog URL: http://teo-en-ming-aka-zhang-enming.blogspot.com > Email: space.time.universe@gmail.com > MSN: teoenming@hotmail.com > Mobile Phone: +65-9648-9798 > Street: Bedok Reservoir Road > Republic of Singapore > > On Mon, Sep 14, 2009 at 3:26 AM, Pasi Kärkkäinen <pasik@iki.fi> wrote: > > > On Mon, Sep 14, 2009 at 02:22:00AM +0800, Mr. Teo En Ming (Zhang Enming) > > wrote: > > > Dear Pasi, > > > > > > Yes, I have tried the nomodeset kernel parameter without result. > > > > > > I couldn''t get Jeremy''s rebase/master branch (pvops dom 0 kernel 2.6.31) > > to > > > work despite disabling all of USB support in the kernel.

I''m presuming you must because Xen always configures it, but these crashes look like something is amiss with it. Also, try a new kernel - as of today - because I just fixed a pretty serious bug. However it should only affect reliability when doing guest IO, not just normal bootup. (It may have some bearing on your performance regression.)

It works. How do I get more than 1 usb device to be passed through to win xp domU? At the moment I can only passthrough the usb optical mouse and not the usb keyboard. I have to use the on-screen keyboard. I have also tried to pass through the OHCI Firewire controller to the win xp domu. Win XP domU device manager reports that the firewire controller is working properly. However, when I plug in my Canon HV20 firewire-based digital camcorder, it cannot be detected at all. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore Blog URL: http://teo-en-ming-aka-zhang-enming.blogspot.com Email: space.time.universe@gmail.com MSN: teoenming@hotmail.com Mobile Phone: +65-9648-9798 Street: Bedok Reservoir Road Republic of Singapore On Sat, Oct 10, 2009 at 5:41 AM, Jeremy Fitzhardinge <jeremy@goop.org> wrote:> On 10/09/09 00:52, Mr. Teo En Ming (Zhang Enming) wrote: >> So if I don''t do a git checkout of a specific branch, the default will >> be xen/master, and at the time of this writing, the pvops dom0 kernel >> will be 2.6.31.1? >> > > Yep, that''s the plan.

Hi,
I have a firewire passthrough script passthru-firewire.sh.
#!/bin/sh
echo "11c1 5811" > /sys/bus/pci/drivers/pci-stub/new_id
echo "0000:02:01.0" >
/sys/bus/pci/devices/0000:02:01.0/driver/unbind
echo "0000:02:01.0" > /sys/bus/pci/drivers/pci-stub/bind
#Unload firewire driver
rmmod firewire_ohci
rmmod firewire_core
I have the pci directive in winxp domU config:
# nvidia & firewire
pci = [ ''01:00.0'',''02:01.0'' ]
01:00.0 is for passing through the nvidia pci express x16 graphics
card and 02:01.0 is the BDF of the OHCI firewire controller.
And I also added the vendorid and productid of the firewire controller
in xend-pci-permissive.sxp.
(unconstrained_dev_ids
#(''0123:4567:89AB:CDEF'')
(''11c1:5811'')
)
This is the first time I am trying to get it to work.

Couldn''t pci-stub be used to passthrough the ohci firewire controller? I had used pci-stub to passthrough the PCI-E x16 graphics card to Windows guest. For firewire controller, must it really use pciback for passthrough? -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore Blog URL: http://teo-en-ming-aka-zhang-enming.blogspot.com Email: space.time.universe@gmail.com MSN: teoenming@hotmail.com Mobile Phone: +65-9648-9798 Street: Bedok Reservoir Road Republic of Singapore On Tue, Oct 13, 2009 at 10:48 PM, Sander Eikelenboom <linux@eikelenboom.it> wrote:> Good to hear pciback is coming soon ! :-) > > > Tuesday, October 13, 2009, 4:22:53 PM, you wrote: > >> On Tue, Oct 13, 2009 at 09:32:08AM +0800, Mr. Teo En Ming (Zhang Enming) wrote: >>> Hi, >>> >>> I have a firewire passthrough script passthru-firewire.sh. >>> >>> #!/bin/sh >>> echo "11c1 5811" > /sys/bus/pci/drivers/pci-stub/new_id >>> echo "0000:02:01.0" > /sys/bus/pci/devices/0000:02:01.0/driver/unbind >>> echo "0000:02:01.0" > /sys/bus/pci/drivers/pci-stub/bind >>> >>> #Unload firewire driver >>> rmmod firewire_ohci >>> rmmod firewire_core >>> >>> I have the pci directive in winxp domU config: >>> >>> # nvidia & firewire >>> pci = [ ''01:00.0'',''02:01.0'' ] >>> >>> 01:00.0 is for passing through the nvidia pci express x16 graphics >>> card and 02:01.0 is the BDF of the OHCI firewire controller. >>> >>> And I also added the vendorid and productid of the firewire controller >>> in xend-pci-permissive.sxp. >>> >>> (unconstrained_dev_ids >>> #(''0123:4567:89AB:CDEF'') >>> (''11c1:5811'') >>> ) >>> >>> This is the first time I am trying to get it to work. > >> It should not work.

The pci-stub is used by qemu to emulate/pass through. If you are using an HVM guest (which you are), then QEMU is the one handling the PCI device. But if you are using a PV guest, you need to have pciback/pcifront support - that is what I am porting over right now. For your issue, I would recompile QEMU with debug enabled in the hw/pass-through.c code and see what is happening. Maybe there are some errors in the log that would explain why it is not working properly? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Re: [Xen-devel] Video Presentation on PCI Express x16 VGA Pass Through to Xen-based Windows XP Home Edition HVM Virtual Machine
Dear All,
I was wrong in stating that only one USB device can be passed through
to Windows XP domU at any one time. In making this assumption, I had
passed through the USB optical mouse only and relied on the onscreen
keyboard as a substitute for the physical USB keyboard.
I realized that I couldn''t get to the QEMU monitor and issue the
"usb_add host:vendorid:productid" command even after I have vnc-ed
into my Windows XP domU. This is because the VNC server is running
within Windows XP guest operating system.
In order to reach the QEMU monitor and execute the usb_add command,
you have to initialize the vnc server built-in to QEMU, which I did
not previously do so.
So today I have re-configured my Windows XP Home Edition virtual
machine configuration, particularly pertaining to vnc settings.
Here is my WinXP HVM configuration:
#import os, re
#arch = os.uname()[4]
#if re.search(''64'', arch):
# arch_libdir = ''lib64''
#else:
# arch_libdir = ''lib''
kernel = "/usr/lib/xen/boot/hvmloader"
builder=''hvm''
memory = 3072
# Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.
#shadow_memory = 8
name = "winxphome32"
vif = [ ''bridge=eth0'' ]
acpi = 1
apic = 1
disk = [ ''phy:/dev/virtualmachines/winxphome32,hda,w'',
''phy:/dev/sr0,hdc:cdrom,r'' ]
#device_model = ''/usr/'' + arch_libdir +
''/xen/bin/qemu-dm''
#device_model = ''/usr/'' + ''lib'' +
''/xen/bin/qemu-dm''
device_model = ''qemu-dm''
#-----------------------------------------------------------------------------
# boot on floppy (a), hard disk (c) or CD-ROM (d)
# default: hard disk, cd-rom, floppy
boot="cd"
sdl=0
vnc=1
vnclisten="<IP address of dom 0>"
vncdisplay=1
vncunused=1
vncconsole=0
vncpasswd=''''
#serial=''pty''
#usbdevice=''tablet''
# onboard
#pci = [ ''00:02.0'' ]
# nvidia & firewire
pci = [ ''01:00.0'',''02:01.0'' ]
vcpus=2
# No passthrough
#gfx_passthru=0
# onboard
#gfx_passthru=1
# nvidia
gfx_passthru=2
# Can only pass through one usb device at a time
usb=1
# USB Unity Green Mouse
#usbdevice = ''host:1bcf:0007''
# USB A1pro Black Mouse
usbdevice = ''host:15d9:0a41''
# USB Keyboard
#usbdevice = ''host:0603:00f2''
# USB Sony IC Recorder
#usbdevice = ''host:054c:0271''
# USB Lexmark X1270 Color Printer
#usbdevice = ''host:043d:00ff''
# USB Lexmark X1270 Photo Scanner
#usbdevice = ''host:043d:007d''
# USB Lexmark X1270 Generic Hub
#usbdevice = ''host:043d:007a''
After I have started Windows XP domU on my Intel DQ45CB, I vnc-ed into
the VNC server built-in to QEMU using my laptop over network. USB
optical mouse was already passed through to WinXP domU as specified in
the HVM config. On the QEMU monitor, I executed "usb_add
host:0603:00f2" to passthrough my USB keyboard. Windows XP domU
immediately detected the presence of the physical USB keyboard.
Now I have both USB optical mouse and USB keyboard passed through to
my Xen-based Windows XP virtual machine.
Sorry Timothy I took so long to figure it out.

Hi All,
I have just installed Slackware64 13.0 64-bit Linux as HVM domU. Please
refer to
http://enmingteo.wordpress.com/2009/11/01/picture-tutorial-how-to-setup-slackware64-13-0-hvm-domu-with-xen-3-5-unstable-pv-ops-dom0-kernel-2-6-31-4-in-fedora-11-x86-64-dom0/for
more details and screenshots.
I have tried to passthrough the firewire controller on Intel DQ45CB

I think that message is misleading. The code shows that it failed to bind the PCI card (02:01:0) to an interrupt and disabled the card. Then it prints the ''registered succesfully!'' which is incorrect. Can you provide the output of: - lspci -vvv (from Dom0) - lspci -vvv (from DomU) - cat /proc/interrupts (from Dom0) _before_ you launch any guests or call bind any devices to the pcistub/pciback. - cat /proc/interrupts (from DomU) after you launch it and try to do stuff with the firewire. For example try to pull videos from your camera via the firewire port.> cirrus vga map change while on lfb mode > pt_iomem_map: e_phys=e3001000 maddr=d3801000 type=0 len=4096 index=0 > first_map=1 > pt_iomem_map: e_phys=e3002000 maddr=d3800000 type=0 len=4096 index=1 > first_map=1 > mapping vram to e0000000 - e0400000 > platform_fixed_ioport: changed ro/rw state of ROM memory area. now is rw > state. > platform_fixed_ioport: changed ro/rw state of ROM memory area. now is ro > state. > *pt_pci_write_config: Warning: Guest attempt to set address to unused Base > Address Register.

The second region is at the wrong location (unless QEMU actually does some copying after each MMIO operation..). I think what you saw before in the QEMU is a good hint. It could be that the QEMU code assumes the BARs addresses have to be in an increased order, whilst in this case it is the reverse.> Capabilities: [44] Power Management version 2 > Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA > PME(D0-,D1-,D2-,D3hot-,D3cold-) > Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- > Kernel driver in use: ohci1394 > Kernel modules: ohci1394 > > > > - cat /proc/interrupts (from Dom0) _before_ you launch >any guests or > > call bind any devices to the pcistub/pciback.> 22: 387742 0 xen-pirq-ioapic-level HDA Intel, firewire_ohciAll right.

I think the issue you pointed out earlier, where the error about the BARs was printed, is the culprit. I am not going to get to this until I am done with the pciback/pcifront work. But it could be that somebody else will pick this bug up in the interim. Can you open a bug on this (http://bugzilla.xensource.com/) and CC me on it? Please include the qemu logs, the dmesg log, /proc/interrupts, lspci -vvv, and anything else you can think off.

What did ''info blocks'' (or maybe it is ''info block'') tell you? Did you look up any guides on how to do this? How do you know the guest did not detect the CD change? Did you try to do a read on it? Like ''sg_readcap /dev/sr0'' or ''dd if=/dev/sr0 of=/tmp/temp.iso'' within the guest? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

RE: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)
Hi En Ming,
I found the line "register_real_device: Error: Binding of interrupt failed!
rc=-1". So I guess the Fire-wire device doesn't support MSI, and
shares IRQ with other devices. This is the issue I and Jeremy are discussing.
You can search mail subject "pv-ops: fix shared irq device
passthrough" in mailing list for more details. Pls apply the attached patch
to pv-ops dom0 see if it fixes your problem.
Regards,
Weidong

Subject: Re: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)
Hi All,
I have just installed Slackware64 13.0 64-bit Linux as HVM domU. Please refer to
http://enmingteo.wordpress.com/2009/11/01/picture-tutorial-how-to-setup-slackware64-13-0-hvm-domu-with-xen-3-5-unstable-pv-ops-dom0-kernel-2-6-31-4-in-fedora-11-x86-64-dom0/
for more details and screenshots.
I have tried to passthrough the firewire controller on Intel DQ45CB motherboard
to Slackware64 13.0 HVM domU but I can't load the kernel modules for it.
Please have a look at the following output within Slackware64 13.0 HVM domU.

From the screenshots of the device manager in the Win XP Home domU,
the OHCI IEEE 1394 firewire controller appears to be working properly.
The Windows drivers for the firewire controller reports that the
firewire controller is working fine.
However, when you connect a firewire-based digital video camera to the
firewire port, it is not detected in the Windows virtual machine.
I will probably have to find time to install a Linux HVM domU and try
to pass through the 1394 controller to it.

Re: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)
Hi Weidong,
I have applied the patch to pv-ops dom0 kernel 2.6.31.5.
Please refer to the following link:
http://enmingteo.files.wordpress.com/2009/11/screenshot-01.png
It does however cause my console terminal in dom0 to be very
sluggish/unresponsive after I have started Slackware64 13.0 HVM.

[Xen-users] RE: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)
I didn't pass-through Fire-wire, and I'm not familar with it. You only
pass-through 02:01.0, why did it access 00:05.0?

After applying the patch to pv-ops dom0 kernel 2.6.31.5, the error
"register_real_device: Error: Binding of interrupt failed! rc=-1"
disappears but the following message still persists.
pt_pci_write_config: Warning: Guest attempt to set address to unused Base

Do we need to do something about the BARs just like in VGA pass-through?

Hi En Ming,
I found the line "register_real_device: Error: Binding of interrupt failed!
rc=-1". So I guess the Fire-wire device doesn't support MSI, and
shares IRQ with other devices. This is the issue I and Jeremy are discussing.
You can search mail subject "pv-ops: fix shared irq device
passthrough" in mailing list for more details. Pls apply the attached patch
to pv-ops dom0 see if it fixes your problem.
Regards,
Weidong

Subject: Re: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)
Hi All,
I have just installed Slackware64 13.0 64-bit Linux as HVM domU. Please refer to
http://enmingteo.wordpress.com/2009/11/01/picture-tutorial-how-to-setup-slackware64-13-0-hvm-domu-with-xen-3-5-unstable-pv-ops-dom0-kernel-2-6-31-4-in-fedora-11-x86-64-dom0/
for more details and screenshots.
I have tried to passthrough the firewire controller on Intel DQ45CB motherboard
to Slackware64 13.0 HVM domU but I can't load the kernel modules for it.
Please have a look at the following output within Slackware64 13.0 HVM domU.

From the screenshots of the device manager in the Win XP Home domU,
the OHCI IEEE 1394 firewire controller appears to be working properly.
The Windows drivers for the firewire controller reports that the
firewire controller is working fine.
However, when you connect a firewire-based digital video camera to the
firewire port, it is not detected in the Windows virtual machine.
I will probably have to find time to install a Linux HVM domU and try
to pass through the 1394 controller to it.

Re: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)
Hi Konrad, I have filed a bug report for the firewire controller passthrough issue at http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1539 and also CCed to you and Weidong.>Uuhh.. What did ''info blocks'' (or maybe it is ''info block'') tell you? >Did >you look up any guides on how to do this? How do you know the >guest >did not detect the CD change? Did you try to do a read on it? >Like ''sg_readcap /dev/sr0'' or ''dd if=/dev/sr0 of=/tmp/temp.iso'' >within theguest? For the case of "phy:/dev/sr0,hdc:cdrom,r" in domU config, i.e. using the physical host CD-ROM/DVD drive, if I want to change physical CD/DVD, I have no problems doing it with "eject" and "change hdc" commands. I can successfully change media. The problem exists with ISO image files, in the case of "file:/path/to/dvd-image.iso,hdc:cdrom.r" in domU config. If you want to change ISO files, it cannot be done at all. After executing eject and change hdc commands, QEMU console will still report "not inserted". I have done it many times. If you try to mount the cd/dvd in domU, it will fail because the change of ISO file is not successful. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore My Primary Blog: http://teo-en-ming-aka-zhang-enming.blogspot.com My Secondary Blog: http://enmingteo.wordpress.com My Youtube videos: http://www.youtube.com/user/enmingteo Email: space.time.universe@gmail.com Mobile Phone (Starhub Prepaid): +65-8369-2618 Street: Bedok Reservoir Road Country: Singapore On Tue, Nov 3, 2009 at 12:05 AM, Konrad Rzeszutek Wilk < konrad.wilk@oracle.com> wrote:> > >Can you provide the lspci -vv output of the Dom0 and >DomU, please? > > .. snip .. > > > Region 0: Memory at d3801000 (32-bit, non-prefetchable) [size=4K] > > Region 1: Memory at d3800000 (32-bit, non-prefetchable) [size=256] > > .. snip .. > > Region 0: Memory at e3001000 (32-bit, non-prefetchable) [size=4K] > > Region 1: Memory at e3002000 (32-bit, non-prefetchable) [size=4K] > > That is weird.
