Hi, I am unable to use my Intel P4600 GPU in a Windows 7 64-bit DomU. Dom0 is CentOS 6.5. I have tried Xen 4.1 with patches, 4.2, 4.3, and currently 4.4 changeset 27214 with patches. I've tried both drivers available from Intel, both installed via exe or zip and Device Manager. Results are either no signal to the monitor or BSOD in Stop 50 in the Intel driver. Here are the most recent results on Xen 4.4 changeset 27214 with the 2 Intel GPU patches from the xen-devel list applied: Intel HD Graphics P4600/P4700 (actually P4600) on Xeon E3-1245 v3 host: PCI 0:02.0 IRQ 32 Windows 7 Ultimate 64-bit No SP or SP1 DomU Primary video in UEFI Setup Driver 10.18.10.3345 (as listed in Device Manager): Installed via .exe installer Primary video in DomU (gfx_passthru=1 and nographic=1): BSOD Stop 50 Secondary video in DomU: BSOD Stop 50 Installed via extracted .zip using Device Manager Primary video in DomU: BSOD Stop 50 Secondary video in DomU: BSOD Stop 50 Driver 9.18.10.3257 (as listed in Device Manager): Installed via extracted .zip using Device Manager Primary video in DomU: BSOD Stop 50 Secondary video in DomU: BSOD Stop 50. igdkmd64.sys listed Address FFFFF880049CA532 base at FFFFF88004843000, DateStamp 51f73f92 Motherboard is a ASRock B85M Pro4 with UEFI v1.90 Attached are logs and DomU config. I appreciate any assistance you can provide. -John Katzmaier _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
