radeon/radeonhd issues with xen domU
 
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 (needed to run the newer
version from testing to support the 4350 card).

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
(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

Strangely enough, installing the proprietary drivers from ATI will allow
DomU to start up 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?

My goal is to run a mythtv frontend on the server, but would like to
keep it in a DomU so it does not interfere with other server operations.

Any help would be much appreciated.

General info:
