Re: [Xen-devel] Fbdev graphics broken in xen/next dom0

I work in the same group as Dave Quigley and George Coker.  I'm working
on a graphical switcher application for Xen which uses the DirectFB
library on top of Linux VESA fbdev.  This runs in dom0 at the moment.
I'm using the latest xen/next pvops dom0 and xen-unstable hypervisor
compiled from source, with vga=ask so I can boot dom0 in a graphical mode.

The problem I'm having is illustrated by the attached test program that
displays a green background with a white square for 10 seconds when run
as root.  It doesn't work on the xen/next / xen-unstable combo.  The
program runs and exits normally but all I see is a black screen.

The program *does* work on xen/next running on the bare metal.  It also
works using the xen-unstable hypervisor with an older dom0, the 2.6.31.4
kernel with Novell patches.  So I think the issue is in the xen/next
kernel.  I've run the test program on different machines and observed
the same behavior.

The xen-unstable / 2.6.31.4 dom0 combination works and I'm using that
for the moment but I'd like to be using pvops.  I would be happy to run
more tests / provide more data if needed.

What's the hardware? Do any messages appear either on the dom0 console or the Xen console? Does booting with a vga console help?

Thanks,
