intel-agp Card support

intel-agp Card support

[Bolaji Beredugo]

I downloaded your xen-2.0 package for my machine only to discover that
it does not include support for intel agp support (even though its
indicated in the kernel recompile options). On finding this is
download the xen-2.0-testing (which was said to contain support for
agp ) and built/recompiled as required only to find out that the
kernel barfs on starting X!

pci card  (as gotten from lspcidrake )is 

 Card:Intel 810  : Intel Corporation|82810E CGC [Chipset Graphics
Controller] [DISPLAY_VGA]

and error encounted (support compiled in ) is 

kobject_register failed for agpgart-intel (-17)
 [<c020c4f0>] kobject_register+0x57/0x65

 [<c025d894>] bus_add_driver+0x50/0xc3

 [<c025de4d>] driver_register+0x2f/0x33

 [<c0216bd5>] pci_register_driver+0x5c/0x84

 [<c982d024>] init_module+0x24/0x31 [intel_agp]

 [<c013694c>] sys_init_module+0x1aa/0x28c

 [<c010d908>] syscall_call+0x7/0xb

I got quite a different error when i compiled agp support as a
modules, output was

agpgart: Detected an Intel i810 E Chipset.
Dec 24 21:08:18 Banshee kernel: agpgart: Maximum main memory to use
for agp memory: 103M
Dec 24 21:08:18 Banshee kernel: agpgart: unable to get memory for
graphics translation table.
Dec 24 21:08:18 Banshee kernel: agpgart: agp_backend_initialize() failed.
Dec 24 21:08:18 Banshee kernel: agpgart-intel: probe of 0000:00:00.0
failed with error -12

I'll be most obliged if this can be treated ASAP as i feel xen is a
great software to make use of and learn from  and would like to use it
on X as soon as possible. Thank  you.

The problem with fixing these device-specific problems is that we
really need to be able to reproduce them ourselves, and we don't
usually have the hardware available to be able to do that. We know
that AGP now works on *some* chipsets, but we don't have a huge range
to test with. 

Your problem looked like it might be a memory allocation failure. Have
you given DOM0 very little memory? Then try giving it a 100M
more. Have you given it all the available memory in your system? Then
try leaving some more slack for Xen to allocate later.

I would be curious to know what an lspci -xxx for that pci device would 
show. One other possibility is that for some reason the size is being read 
incorrectly and the driver is trying to allocate 0xffffffff bytes of 
memory (I've seen this happen in other contexts).

Mr Keir, i'll try out your suggestion ASAP and give feedback, its just
that it takes a while for me to get to it as i would have to reboot my
Workstation everytime. thanks
