I have been trying to export my ATI HD4350 graphics card to a domU.
The device is blocked in Dom0 using pciback along with a few other
devices and is visible in DomU. All other pci devices work fine.
I first tried the radeonhd driver version 1.2.5.
The tail end of the Xorg.0.log showed the following errors:
(--) RADEONHD(0): Detected an RV710 on an unidentified card
(II) RADEONHD(0): Mapped IO @ 0xfdee0000 to 0xb7a8b000 (size 0x00010000)
(II) RADEONHD(0): PCIE Card Detected
(EE) RADEONHD(0): Cannot allocate 0 bytes of memory for BIOS image
(II) RADEONHD(0): Query for AtomBIOS Init: failed
(**) RADEONHD(0): Using AtomBIOS for All
(EE) RADEONHD(0): No AtomBIOS image found but required for AtomBIOS
based mode setting
(II) RADEONHD(0): Query for AtomBIOS Teardown: failed
(II) UnloadModule: "radeonhd"
(EE) Screen(s) found, but none have a usable configuration.
Fatal server error:
no screens found
When starting X, the display would flash 3 times.
I tried using the radeon driver, and received the following error in the
Xorg log:
(--) RADEONHD(0): Detected an RV710 on an unidentified card
(II) RADEONHD(0): Mapped IO @ 0xfdee0000 to 0xb7a8b000 (size 0x00010000)
(II) RADEONHD(0): PCIE Card Detected
(EE) RADEONHD(0): Cannot allocate 0 bytes of memory for BIOS image

(EE) RADEONHD(0): No AtomBIOS image found but required for AtomBIOS

(II) RADEONHD(0): Query for AtomBIOS Teardown: failed
(II) UnloadModule: "radeonhd"
(EE) Screen(s) found, but none have a usable configuration.
Fatal server error:
no screens found
Strangely enough, installing the proprietary drivers from ATI will allow
DomU and X to start up and some applications will function but utilities
like flgrxinfo will error out. The end result was not stable.
Has anyone been able to get this to work? Any hints or ideas? I am
finding mixed information on the ''export video card to DomU''
issue. Some
people are claiming success, some say it is not possible.
Any help would be much appreciated.

All other pci devices work fine. >So you have a PV domU? I think all the people who have gotten VGA/Graphics passthrough working have been using HVM guests with custom patched Xen. Also you should be aware that passing through VGA/graphics adapter is not as simple as normal PCI device. VGA/Graphics adapters have other stuff than "just the PCI device".. like legacy io-ports and memory ranges. Those need to be passed through aswell. And the VGA BIOS needs to be executed in the guest.. which can be difficult (or even impossible) in a PV guest.. So it might (and will) require extra patches to the Xen hypervisor and possibly dom0 kernel to make it work.
