compile error on kernel 2.4.29-xenU

[Marco Genise]

Hi,

when I try to compile a custom kernel 2.4.29 with option "Device driver
domain" enabled, I get following error during "make ARCH=xen":

arch/xen/drivers/blkif/drv.o(.text+0x35e0): In function `blkif_connect':
: undefined reference to `direct_remap_area_pages'
arch/xen/drivers/netif/drv.o(.text+0x1a95): In function `netif_connect':
: undefined reference to `direct_remap_area_pages'
arch/xen/drivers/netif/drv.o(.text+0x1ad4): In function `netif_connect':
: undefined reference to `direct_remap_area_pages'

When I disable the option compiling finishes without any problem.

My domain0 kernel is version 2.6.11, other domains run with 2.6.11-xenU
without any privileged access. Current Xen version used is
xen-2.0-testing. Same error occured with xen-2.0.5-stable. Didn't test
with xen-unstable right now.

Anyone got a hint what the problem might be?

Thanks in advance,

Marco.

Compare your config for 2.4.29 against that of the 2.4.29 xen0 config.
It is able to build and host native drivers just fine.

It's likely the config dependencies need tweaking to prevent you
slecting an illegal combination of some sort.

Best,
Ian

Ok, that was the problem. Seems I had some illegal combinations in my
config. Now it works, thank you.

This will happen if you don't enable the privileged domain option as well as 
physical device access.

Cheers,

It would be good to add this as a dependency. Patches welcome :-)
Thanks,
Ian
