Xen devel - May 2005 - x86_64 compile error / isa_bus_to_virt_needs_PRIVILEGED_BUILD

Using FC3 x86_64 and doing "make ARCH=xen world", I get the
following:

  CC      arch/xen/x86_64/kernel/mpparse.o
arch/xen/x86_64/kernel/mpparse.c: In function `get_smp_config'':

make[1]: *** [linux-2.6-xenU-build] Error 2

On a complete guess -
The .config shows:
 # CONFIG_XEN_PHYSDEV_ACCESS is not set

Why does include/asm-xen/asm-x86_64/io.h not seem to do this
properly with:

#ifdef CONFIG_XEN_PHYSDEV_ACCESS
#define isa_bus_to_virt(_x) (void *)(__fix_to_virt(FIX_ISAMAP_BEGIN) + (_x))
#else
#define isa_bus_to_virt(_x) isa_bus_to_virt_needs_PRIVILEGED_BUILD
#endif

xen0 compiles fine.

The issue is that x86-64 Kconfig defaults these two to y.

CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y

Can you try turning them off?

We''re still in the process of sorting out x86/64 dom0 -- domU is not at
all expected to work or even build. No control tools for booting domUs 
are checked in yet anyway.

Ok. Thanks for the info.
I was informed on irc #xen to wait at least a couple of weeks,
before anything stable is to show up in the x86_64.

If CONFIG_X86_IO_APIC=n, you shouldn''t be trying to build mpparse.c. 
Please try the updated patch I just sent.

It''s true that x86-64 xenlinux is not for public consumption yet, but
we''ll be surprised if dom0 does not boot or run well even at this
point.
We checked: 

Latest ChangeSet: 2005/05/23 19:35:08 1.1516
4292225caWyLsfo-mZ3yV4QmUhXSAQ

It worked on both UP & DP systems with ACPI on. On DP system if acpi=off
is given to both xen & dom0 it works. So please build xen and dom0, and
test that on x86-64 as well before you deliver changes if affect x86-64.

This worked. Both xen0 and xenU compile.

It won''t boot xen0, I get

VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "sda1" or unknown-block(2,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(2,0)

my grub looks like:

title Fedora Core (2.6.11-initrd-xen0)
        root (hd0,1)
        kernel /boot/xen.gz dom0_mem=262144 noreboot
        module /boot/vmlinuz-2.6.11.10-xen0 ro root=/dev/sda2
        module /boot/initrd-2.6.11.10-xen0.img

Does it work out-of-the-box with SATA drives?

Please post the full dmesg with and without xen. It works with SATA 
drives for me.
