I am attempting to fix the kexec interactions with x2apic and iommu
functionality. Part of this involves ensuring that all IOMMU
functionality is disabled, as the kdump kernels are not happy at having
their interrupts remapped without their knowledge.
I have introduced iommu_disable_x2apic_IR() onto the kexec path, but it
does not seem to actually disable interrupt remapping on Intel boxes
(Specifically the two Intel Nehalem boxes I am testing on).
Specifying iommu=no-intremap on the commandline causes everything to
work correctly, but leaving it out causes the kdump kernel to hang and
eventually reboot, as can be seen on the attached serial log.
The lines starting DBG: are extra debugging I have put in which shows
that the disable_IR() function is being called and writing to the registers.
This problem occurs with the XenServer version of 4.1.0 as well as on
xen-unstable at the moment.
Is there any hardware state which is not taken down by the disable
function, any subtle interactions which I have not taken account of? I
have looked through the source and nothing pops out, but I am out of ideas.
Thanks in advance,

Should have attached your patch as well. Noone else can know with certainty
where you put your debugging, and noone else is going to want to help debug
your code if they can't even see it. :-)
Also a good idea to Cc a likely person who can help (i.e., someone who wrote
the code that you are querying). 'hg annotate' is useful for this -- in this
case I am adding Weidong Han to the cc list.
On the bright side, this must have been got working for S3 suspend/resume to
work properly (indeed that's what the disable code was originally added
for). So it can't be an insurmountable problem.

Attached are the two relevant patches, and two which I don't think are
relevant but might be if I am wrong. crash_shutdown was an attempt to
make an iommu_ops which shut down all iommu functionality without saving
state. debug-wip shows where I have put in debug statements.
kdump-fix-x2apic and apic-record-boot-mode are also in the source, but I
believe them to be unrelated to the current problem.
I have done some further debugging on the assumption that the order of
shutting down interupt remapping matters with shutting down the lapics
and ioapics, but disable_qinval causes a panic (qinval.c:222 - "queue
invalidate wait descriptor was not executed\n") if it is run before both
the lapics and ioapics are shut down.

IOMMU: add crash_shutdown iommu_op
The kdump kernel has problems booting with interrupt/dma
remapping enabled, so we need a new iommu_ops called
crash_shutdown which is basically suspend but doesn't
need to bother saving state.
We make sure that crash_shutdown is called on the kexec
path.

APIC: record local APIC state on boot
Xen does not store the boot local APIC state which leads to problems
when shutting down for a kexec jump. This patch records the boot
state so we can return to the boot state when kexecing.

KEXEC: correctly revert x2apic state when kexecing
Introduce the boolean variable 'kexecing' which indicates to
the more general functions whether we are on the kexec path
or not. This is used by disable_local_APIC() to try and revert
the APIC mode back to how it was found on boot, and used by
hpet_disable_legacy_broadcast() to prevent it IPI'ing the
other processors after they have already been shot down.
We also need some fudging of the x2apic_enabled variable
to prevent a protection fault when disabling the IOAPICs.
Finally, make sure we dont jump into the purgatory code with
interupts enabled. We dont want to be servicing stray
interupts once we are out of Xen.

By the way, Weidong's email is dead. Cc'ing Allen Kay (the VT-d maintainer)

I think what you need to do ought to be quite similar to the teardown we do
for S3 suspend. Have you considered reusing some of the mechanism in
arch/x86/acpi/power.c? The function device_power_down(), and possibly some
other bits in its caller, would be especially useful I should think. It
already shuts down iommu functionality, turns off x2apic, etc etc. Even if
it is not a perfect fit as is, perhaps it could be fixed up -- it sure looks
similar to what ypu're trying to do. :-)

On a hunch, I tried that last night, and it resulted in the kdump kernel
hanging indefinitely (well - 14 hours now) on checking the hlt
instruction. I will continue to play around with that area though, as
it does seem like a sensible idea.
