Thanks for testing it out. We have
tested this patch with Radeon 4850, 4870, FirePro V5700 and FirePro M5800.
Unfortunately we don’t have V3750 at hand. It is very possible this patch
isn’t compatible with V3750. We will try to get hold of one for
debugging. For graphics which work with this path, users should be able to get
rid of emulated gfx (such as Cirrus). I have successfully installed a Windows
guest VM using this patch.
I also want to point out that
there is still an issue. Users will see a black screen after installing
Catalyst driver. Even though the screen appears to be black, the driver is
actually functioning correctly (3DMark can be run with external monitor). Our
driver team is currently debugging it and they believe this is easy to fix.
What is your opinion on this
patch (and the solution) in general?

Subject: RE: [RFC][QEMU] ATI graphics VBIOS passthru support
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?

Subject: [RFC][QEMU] ATI graphics VBIOS passthru support
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.
