I'm also doing some testing but seems we didn't meet a similar issue

Which CPU are you using?
My Haswell desktop CPU (Core i5-4670) doesn't have the same IGD as
yours.
And, I'll have some update after I doing more testing.

Hello Yongjie,

Can you please describe the following info about your GPU passthru
setup:
- Xen hypervisor version/changeset
- Any patches to Xen?
- Cmdline options to Xen
- dom0 linux kernel version
- Cmdline options to dom0 linux kernel
- HVM guest OS/version
- IGD driver version in the HVM guest
- dom0 configuration and settings; I assume you're using xen-pciback?
Did you blacklist igd driver in dom0 kernel? etc.
I think that'd be helpful for others to get a similar baseline configuration.

Thanks,

-- Pasi


Dear Yongjie,

Could you share with us your hardware and software configuration
settings?

Sure. My IGD is also Intel HD Graphics 4600. :-)

1. hypervisor version: c/s 26666 in xen-unstable.hg tree  (5 months ago)
   traditional qemu commit: 5ae58eaa967495fce99b727422054c58750d252b
   Dom0 kernel: Linux 3.8.1
N.B. I didn't use the latest traditional qemu because of the following bug:
http://bugzilla-archived.xenproject.org//bugzilla/show_bug.cgi?id=1865

2. no offline patch. (just use the code in the tree I mentioned above.)

3. hypervisor options: dom0_mem=1024M iommu=1 loglvl=all guest_loglvl=all unrestricted_guest=1 msi=1
   dom0 kernel options: ro root=/dev/sda1

4. HVM guest: Windows 7 Enterprise

5. IGD driver version in HVM: 9.18.10.3165
   got to: https://downloadcenter.intel.com/
   then, search "4th Generation Intel Core Processors with intel hd graphics 4600" to download the driver.

6. use 'xl pci-assignable-add $BDF' to add the IGD as assignable.
   (it also use 'xen.pciback' driver.)

7. dom0 kernel config is attached as file 'config-3.8.1'.

8. HVM guest config file:
builder= "hvm"
name= "vga-passthrough"
memory =1024
vcpus=4
device_model_override= '/usr/lib/xen/bin/qemu-dm'
device_model_version= 'qemu-xen-traditional'
disk = [ '/images/ia32e_win7.qcow,qcow2,xvda,rw' ]
vnc=1
serial='pty'
usb = 1
usbdevice = 'tablet'
gfx_passthru=1
pci = ['00:02.0','00:1d.0','07:00.0']  #'00:02.0' is IGD; the other two are mouse and keyboard.

9. I can successfully assign this IGD 4600 (in Core i5-4670 CPU) to the Windows guest. And the IGD can work fine.
   See some attached pictures for more info.

How can I fix this issue?

Thank you very much.


Hi,

With reference to this thread http://www.gossamer-threads.com/lists/xen/devel/283347, I tried to workaround the above-mentioned problem. The following are steps I have taken to compile and install Xen 4.3-unstable changeset 26666.

cd
hg clone -r 26666 http://xenbits.xensource.com/xen-unstable.hg xen-unstable.hg-cs26666
cd xen-unstable.hg-cs26666
./configure
make world
cd
git clone git://xenbits.xen.org/qemu-xen-unstable.git
cd qemu-xen-unstable
cp -a * /home/teo-en-ming/xen-unstable.hg-cs26666/tools/qemu-xen-traditional-dir-remote
cd ..
cd xen-unstable.hg-cs26666
sudo -s
./configure
make world
make install

Xen 4.3-unstable changeset 26666 compiles and installs successfully. However...

It appears that my Xen 4.3-unstable changeset 26666 installation is broken. How do I fix this issue? Are there any mistakes in the steps I have taken?

Thank you very much.

How do I use LDFLAGS to solve the compile error?

Yours sincerely,

Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Hi,

From what I have read, you need to make a change to the Makefile and add in "lrt". But I don't know how to make changes to the Makefile.

Reference: https://answers.launchpad.net/ubuntu/+source/gcc-defaults/+question/149617

mycae: you will need to modify the Makefile to add -lglib to your linker arguments (i.e. the gcc call that makes either the lib or the executable file).

Yours sincerely,

Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Hi, I have solved the compile error. The following are steps I have used to solve the compile error.

cd

hg clone -r 26666 http://xenbits.xensource.com/xen-unstable.hg xen-unstable.hg-cs26666

cd xen-unstable.hg-cs26666

sudo -s

./configure

Even though I have solved the compile error and successfully compiled and installed Xen 4.3-unstable changeset 26666, it is broken and not usable.

Please refer to the following errors.
