I think you''re running into a known bug in current mainline Linux
kernels, in which 32-bit compat syscalls are not being handled properly
on AMD systems.  The workaround is to boot with "vdso32=0" on the
kernel
command line.  Unfortunately nobody has taked the time to really work
out what''s going on (I don''t have an AMD system on hand, which
makes it
awkward).  It appears to be a problem with returning from a syscall,
rather than the syscall itself.

After fresh git clone, git checkout tune "make menuconfig" the same
way as for RC6

Where did you clone this from? Is it the vanilla Linux kernel, or
xentinized kernel?

Where did you clone this from? Is it the vanilla Linux kernel, or
xentinized kernel?

thanks,

I think there is a conflict between the newer drm code and swiotlb. I have 
seen this for a while on my Fedora builds as Fedora Rawhide seems to get 
the new drm code before it makes it into the official kernel. You can work 
around it by disabling a small number of drm related kernel options, 
though you probably lose some functionality by doing so.

After this change:-

   -*- /dev/agpgart (AGP Support) 
--->                                                 
   < > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) 

i was able to build 2.6.31-rc8 (with Xen Dom0 support).

However, attempt to load 2.6.31-rc8 either under Xen 3.5 or Xen 3.4.1 causes
console to drop into stack trace and hangs.

Thank you.
Boris.

I''ve had the same problem since his Jeremy''s branch went from
rc6 to rc8
this week.  I can boot the kernel on bare metal, but not under Xen as
dom0.

  Now kernel gets built, but still fails to load under either Xen 3.5 or Xen
3.4.1.
  Stack traces differ on C2D E8400 (Xen 3.4.1)  and Q9550 (Xen 3.5 unstable
)boxes.
  On the last box :-

 do_one_initcall + 0x37/0x1a0
 kernel_init + 0x164/0x1ba
 child_rip + 0xa/0x20
 ? int_ret_from_sys_call 0x7/0x16
 ? retint_restore_arg + 0x5/0x6
 ? child_rip 0x0/0x20

 Two last commands are the same on the first box. Previous differ.

Boris.
P.S. I cannot buy or order 20 m of NUL modem cable.
       Just 2.5 m . That''s all

I believe, that some set of CSs from Xen 3.5 has to be included as patches into
xen-3.4.1-3.src.rpm, in case if it causes by 3.4.1 Hypervisor.
Otherwise  , F12 release in November won''t have suitable Dom0 kernel
again.
I would guess 2.6.31-rc6 at best.

Boris.

"Dom0 status: awaiting upstream kernel support"

-- Pasi

As far as Xen 3.5 tarball will be officially released  kernel supporting Dom0
should be
JF''s pvops kernel. When  xen-3.5.0-X.src.rpm and updated libvirt ( next
preview)

As far as Xen 3.5 tarball will be officially released  kernel supporting Dom0
should be
JF''s pvops kernel. When  xen-3.5.0-X.src.rpm and updated libvirt ( next
preview)
will become available via F13 rawhide , F12 & F13 rawhide would be ready to
go
in text mode as 3.5 Xen Hosts with virt-install&virt-manager available via
VNC
connections.  Why wait until Upstream merge ?

Uhm.. sorry I''m a bit confused. If I understood correctly you have a
call trace on your pv_ops dom0 kernel? 

Does that only happen with Xen 3.4.1 or what''s the problem?

Pasi,

I was trying to load the most recent 2.6.31-rc8 under Xen 3.4.1 ( via src.rpm)
on F12
rawhide and got stack trace. Jeremy is saying that rc8 works ok under Xen
Unstable.
But, Libvirt 0.7.0-6 would obviously have dependencies  on xen-3.4.1 packages.
If i will port Xen 3.5 directly to F12 (F11) it might work with rc8, however
Libvirt 0.7.0-6 will be most probably lost again. Libvirt 0.7.0-6 has been built
for 3.4.1 Hypervisor ( in my understanding) . That''s why i wrote if Xen
3.5 can load rc8, the easiest way to fix
issue is to backport required Xen 3.5 CSs to xen-3.4.1-X(?).src.rpm  and get it
resolved before F12 November''s release.

I lost one thing. After backport xen-libs-3.4.1 would be updated, hence libvirt
might
require another changes as well.

Kernel gets built, but fails to load under Xen 3.4.1 (F12 rawhide)
Does it make sense to update  include/xen/swiotlb.h in the same way ?

I''ve got the same stack trace on F11 with the most recent "yum
update" under Xen Unstable for 2.6.31-rc8 ( top commit
7c62209cde5b13b81685e79b2f9e3757e293aef1)

I just compiled latest 2.6.31-rc8 pv_ops dom0 kernel (commit
7c62209cde5b13b81685e79b2f9e3757e293aef1) and it works for me.

I''m running with xen-3.4.1-3 on Fedora 11 (x86 32bit PAE). 

.config for my working kernel:
