noise appears with Intel HD graphics 4600 IGD passthrough
Hi all, I have installed Xen and Windows 7 domU in Ubuntu 12.04 dom0. I tried following versions of Xen and dom0 linux kernel. Xen: 4.3, 4.4-unstable(revision 27363) kernel: 3.10.7, 3.11.0-rc6 I tried to passthrough the Intel HD graphics 4600 IGD to the domU, and it is successful. Refer to the dxdiag screenshot. However, when I ran 3DMark Basic Edition or some other benchmarks, there is often noise across the screen as the attached screenshot. How can I remove this noise? Please advise.

Could you share with us your GRUB2 configuration, Windows 7 HVM domU configuration, and Linux kernel configuration file? Thank you very much. -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming) _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

I attach the grub configration file, HVM domU configuration file, and kernel configuration file. I am trying with Xen 4.2.2 now, so xen 4.2.2 is set in the grub file. I have installed xen and dom0 kernel by referring to these pages and so. - http://wiki.xen.org/wiki/XenPCIpassthrough - http://wiki.xen.org/wiki/Xen_VGA_Passthrough - http://xen.1045712.n5.nabble.com/Latest-Xen-Linux-Kernel-and-VGA-Passthrough-Tutorials-td5718127.html I have built dom0 kernel by these commands. $ make menuconfig $ make -j8 # make modules_install install In menuconfig I checked 4 options and the others were default. 1. Processor type and features -> Linux guest support -> Enable paravirtualization code -> Xen guest support 2. Power management and ACPI options -> ACPI (Advanced Configuration and Power Interface) support -> Deprecated /proc/acpi files 3. Device Drivers -> Network device support -> Xen backend network device 4. Device Drivers -> Block Devices -> Xen block-device backend driver And I have built Xen by these commands. $ make world # make install For passthrough vga device, I use these commands. # echo 0000:00:02.0 > /sys/bus/pci/devices/0000:00:02.0/driver/unbind # echo 0000:00:02.0 > /sys/bus/pci/drivers/pciback/new_slot # echo 0000:00:02.0 > /sys/bus/pci/drivers/pciback/bind Best regards, Kento> -- > Yours sincerely, > > Singapore Citizen Mr. Teo En Ming (Zhang Enming) > > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xen.org > http://lists.xen.org/xen-users >_______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
