Blank screen while loading AMD/ATI graphics driver (fglrx) in Dom0 (Linux 3.0/3.2) with Xen 4.1/4.2

Blank screen while loading AMD/ATI graphics driver (fglrx) in Dom0 (Linux 3.0/3.2) with Xen 4.1/4.2

[sahilsuneja]

Hi,

I had posted the following issue a few days ago in Xen-users but I haven't
received any answer yet. So I decided to re-post it here in hope for some
solution. 

Here's the original post:

Xen wiki states that using linux 3.0 and above as dom0 works with all
graphics cards. I could install the fglrx graphics driver on my desktop
machine with a discrete graphics card (Radeon HD 5870), but I see a blank
screen while loading fglrx on my AMD Fusion E350 machine with integrated
graphics card (Radeon HD 6310). The graphics driver loads fine when the
Linux kernel runs alone not as Dom0. I am using the latest driver from AMD's
website (ATI Catalyst 12.1).

I also see the following towards the end of xm dmesg on Fusion, I wonder if
this is related:

0x0000000000000000 to 0x000000000000abcd.
(XEN) APIC error on CPU0: 00(80)

Does any one have a reason / solution, please?

So try the open source one - then you might at least be able to debug the
problem.

Ask AMD - they have the Xen code, nobody else has their bits.

I already did that; Dom0 boots up without issues with the open source RADEON
driver, however the xm dmesg errors remain.

Really? Thanks.

Re: Blank screen while loading AMD/ATI graphics driver (fglrx) in Dom0 (Linux 3.0/3.2) with Xen 4.1/4.2

[sahilsuneja]

Wow, that does indeed solve the problem.
Thanks a lot Konrad, I guess I should have used the linux kernel from your
or Jeremy's git repo in the first place itself. But, on my machine with the
discrete graphics card, xen worked on ubuntu's native linux-3.2 kernel, and
hence I never gave it a thought to try a kernel from the xen-linux git repos
(which I've always done before).

Regards,
Sahil

Right. That is b/c the built-in drivers - radeon and nouveau work without
any issues. Third-party drivers are a different case and require some tweaking.

Hmm, and I am guessing in the discrete graphics card case, fglrx driver
loading doesn't need to access the low 1MB mem region to obtain the "video
bios signature" as it gets this from the pci mapped memory region instead?
