X11 on domU

X11 on domU

[Julian Davison]

Hi,

I'm not certain whether this belongs in 'users' or 'devel',
the topic appears to turn up in both lists. I've tried 'users'
but with no joy...

What we'd like to do is run several independant X11's on a
single CPU box. Using on-board (AGP) graphics, and additional
(PCI) graphics cards, and various USB controllers for the
keyboard/mice combos.
The aim is to have three 'consoles', each with a browser
running to provide access to our library catalogue. With
Xen we should be able to isolate each console in its own
dom, ensuring that one user can't so easily ruin others
functionality.

I'm running Debian 3.1 sarge/stable as dom0.
I've got Xen 3.0.2 stable sources and built them with
to include the pciback module. Using pciback I can happily
have various devices show up in domU (ethernet, USB controller
and graphics) with things like 'lspci'. The obvious stuff
just plain works - I can use the ethernet card instead of
the virtual ethernet, find USB devices.
I 'upgraded' domU to debian unstable, to get a more
recent Xorg setup, but I still get stuck.

Using "X -novtswitch -sharevts vt1" I ended up being told:

-------------- copy of end of X output starts --------------
(EE) I810(0): Cannot map SYS BIOS

Fatal server error:
xf86MapVidMem: Could not mmap framebuffer (0x000a0000,0x10000) (Bad address)
--------------  copy of end of X output ends  --------------

At this point I'm out of ideas :)

Anyone have any pointers or ideas?




J,

As well as mapping the linear framebuffer, this particular X driver
wants to map the VGA memory area at 0xa0000. 

As an experiment, trying hacking in a call to the following in
setupDevice in pciif.py: 

 xc.domain_iomem_permission(dom = fe_domid,
                    first_pfn = 0xA0000>>PAGE_SHIFT,
                    nr_pfns = 0x10000>>PAGE_SHIFT,
                    allow_access = True) 

You may also need to map the VGA BIOS, in which case use nr_pfns =
0x27FFF>>PAGE_SHIFT 

Please let me know if this works.

Best,
Ian

It results in a leap forward, but still falls short :)
I did need the VGA BIOS (0x277FFF) which results in
X starting up(ish) but displaying a black screen with
a white square near the middle, then stalling.
A ctrl-C in the starting terminal causes X to exit,
with the error:

This is pretty weird. I wander if its relying on an interrupt that isn't
getting plumbed through? Is there any mention of an interrupt in the X
startup logs? Please could you post these.

[In fact, how does the X server get hold an interrupt from user space
(hence enabling it to block)? ]

Does the i810 driver cause any nasty kernel modules to be loaded such as
agpgart or something? The domU would need to be given access rights to
the GART, but I can't immediately think why it wouldn't work. Obviously,
the GART couldn't be shared between domU's.

One other option might be to try and use the fbdev driver in the kernel
(and X's fbdev module) rather than X's i810 driver.
 
Thanks,
Ian

I've attached the Xorg.0.log file

Pass.

So yes, agpgart gets loaded. Do I need to setup something
for the DomU to get access to it? (I'm somewhat hazy on what,
exactly, needs to be done where :)
Sharing shouldn't be a problem as (I understand) agpgart
only applies to AGP cards and any/all additional video
cards will be PCI.

I'll see how that goes.
