Thread-topic: [RFC][QEMU] ATI graphics VBIOS passthru support

Hi Wei,


This patch did not cause any problems with Intel IGD passthrough for me.  However, the monitor remained blank if I pass through ATI Firepro V3750 either as the primary display device or the secondary device (gfx_passthru=1/0).  Passing it through as the secondary device used to work.


Have you tested the patch with this graphics card?

Hi Ian,


There have been a lot of interest on gfx passthru recently. This patch enables ATI VBIOS in passthru mode. The guest VM system BIOS (including Windows boot logo) can now show in passthru screen. We have tested with various Windows and Linux guest VMs. Please help review it. We are also looking forward to comments and suggestions from Xen community users.
