While I'm still not really happy with the changes done, and the VGA
(or not) handling in general, after discussing this yet another time
with Andrew we've decided to put in at least the first 4 patches. The
rest of the series will need to have the reported regression (by
Doug) taken care of to become a candidate for committing.

I'm on travel for the next week and half but when I return I had planned
on tackling the issue.

For anyone else interested its reproducible with QEMU booting smp with 2
CPUs and using OVMF. Xen just never sees more than the boot CPU. I'd
recommend using QEMU master since they landed some fixes so that the
debugger can handle switching from 64-bit to 32-bit and back again.

Thanks a lot!

I tried to reproduce this on my machines and some guys from my team
did also some tests. We were not able to reproduce anything reported
by Doug. Recently I repeated the tests on QEMU 2.8.0 with OVMF from
https://www.kraxel.org/repos/jenkins/edk2/ (20170213.b2458.g5b97eb4).
Without any issues too. I need more details about tests environments
(exact host kernel version and config, QEMU and OVMF versions and config,
exact Xen and dom0 kernel versions and config, etc.). It would be nice
to get access to one of these physical machines on which issues are
surfacing too.

I'm currently at ELC and then on vacation so I don't have access to any
of the machines currently myself. However the machine I most use to test
is a NUC5i5MYHE and a NUC5i3MYHE if you want to ask around if someone
has one internally. But that's why I gave QEMU as an example.

I was using qemu master from a few weeks ago. I'll have to find the
revision for you. But the command line I use is:

-enable-kvm -M pc-q35-2.8 -device intel-iommu -cpu host -m 2048 -smp 2
-drive if=pflash,format=raw,file=/tmp/tmp.EiR6ixmYzV -global

Sadly, my colleagues and I are not able to reproduce the problem on any of
machines available for us (available on the market and some development
stuff in our labs). I did tests with QEMU (I am not able to run it with
"-device intel-iommu" on my machine; I have to investigate this). Everything
works. Joao did some tests on Intel NUC D34010WYK second generation.
Everything works. So, Konrad ordered Intel NUC NUC5i3MYHE for me. I am
waiting for delivery. Doug, could you tell me what distro, Xen, etc. you
have installed on that NUC? I would like to test same config as yours on
this machine.

I had a chat with Doug on IRC and:
 - I had tested earlier on AMD, while he has only Intel boxes,
 - He was wondering if this was an IOMMU issue.

So to double-check that, I installed Ubuntu 16.10 on my X11SAE
SuperMicro, which has an Haswell E3-1245 v5 and with IOMMU enabled.

I tested the 'origin/staging' xen.gz build with the upstream grub2
(I just used the 'master' branch) first and also just booting xen.efi.

Both worked fine.

Then I used v16 of Daniel's patches (this thread). They are also
now on	git://xenbits.xen.org/people/konradwilk/xen.git mb2.v16
also the same way - as xen.efi and then using grub.efi and booting it
(see below)

All worked fine.

Now in the process I discovered that my patch for grub-mkconfig to
detect multiboot2 payloads and use those instead of multiboot never
made it upstream, so I had to modify my grub.cfg by hand (see below).

xen.cfg:

I had and still have a feeling that it can be related to IOMMU. I will
try to reproduce this on QEMU but first of all I have to check how to
enable this option in my environment (something is broken). Additionally,
there is a chance that the issue spotted by osstest (fixed right now)
played a role here too. So, it will be nice if Doug can do tests with
latest master. Anyway, I will do tests too. Though I am still waiting
for my NUC.

Great! Thanks a lot for doing the tests.

It will be nice if you post it after GRUB2 2.02 release.

Latest QEMU from git with intel-iommu device enabled works without any issue.
Though it looks that I found a bug in Xen IOMMU code. If I run Xen from master
in QEMU then QEMU complains and crashes:

  qemu-system-x86_64: /srv/dev/qemu/qemu_20170308/hw/i386/intel_iommu.c:1786: vtd_mem_write: Assertion `size == 4' failed.
  Aborted (core dumped)

So, I took a look at dma_msi_set_affinity() and found this:

  dmar_writeq(iommu->reg, DMAR_FEADDR_REG, msg.address);

It looks bogus because DMAR_FEADDR_REG is defined in spec as 32-bit wide.
So, applied this patch:

-    dmar_writeq(iommu->reg, DMAR_FEADDR_REG, msg.address);
+    dmar_writel(iommu->reg, DMAR_FEADDR_REG, msg.address_lo);
+    if (x2apic_enabled)
+        dmar_writel(iommu->reg, DMAR_FEUADDR_REG, msg.address_hi);

Ant it looks that right now everything works.

If patch make sense I can post it with proper commit message.

EFI aside, that is clearly a qemu bug (as Xen shouldn't be able to cause
an assertion like that to be hit), and there is nothing wrong with Xens
code as-is.

All the spec requires is that 32bit fields are accessed as whole
doublewords (rather than smaller units).  There is no restriction on
updating two adjacent 32bit fields with a quadword access. 
(Furthermore, hardware is requires to cope with accesses to a 64bit
field being decomposed into two 32bit accesses.)

Please see commit ae05fd3912 ("VT-d: use qword MMIO access for
MSI address writes") before you consider posting a patch.

Well if this was really the IOMMU issue then there's already a patch in

So as I've mentioned you have to run 'xl info' and look at nr_cpus to

Odd, I must have missed it. Either way see the inline serial capture.
With both 'xl info' reporting expected values.

Got Intel NUC5i3MYHE (internally it is NUC5i3MYBE board) into my hands.
I have put 8 GiB RAM and 500 GB SATA 3 into it. Updated BIOS/EFI to 0041
version (it is the latest one). Installed latest Debian testing (Debian
GNU/Linux 9 (stretch)), built GRUB2 and Xen, with and without relocation
patches, on it. Everything works (I left machine working last night).
Guest boots without any issue. Please take look at attached logs.

Doug, could you tell me how exactly did you test your machine? I need OS
type, version, C version (GCC, clang, anything else), bintuils version,
etc. "xl dmesg", "xl info" and "dmesg" full outputs are welcome too.

I thought I already responded to Konrad saying that latest staging +
relocation patches also comes up.

My guess is that it is related to the IOMMU "fix" that Andrew and Jan
did by #if 0'ing out some of ebmalloc. But I'm not sure. I haven't had
time to look at any of this stuff lately. I went to ELC and then
vacation and then managed to hurt myself on vacation so I've been away
from my computer a bit.

All my branches are available in https://github.com/cardoe/xen and I've
been on Ubuntu 16.04.

I do not remember it. Maybe I have missed that.

I reenabled free_ebmalloc_unused_mem() during QEMU tests last week.
It has not changed anything. I will do the same on my NUC.

Where's the branch you are using on that NUC? Because you can't be using
plain staging on there because the firmware version you reported dead
locks when the EFI GetTime() is called. Its a known issue by Intel. So
you must be patching that out of your Xen?

I rebased relocation patches (v16) on top of 9dc1e0cd81ee469d638d1962a92d9b4bd2972bfa
(x86/pagewalk: Consistently use guest_walk_*() helpers for translation) commit.
No more no less. Everything works. Am I missing something?

Everything works. I am not able to reproduce any issues reported by Doug.
Andrew, Jan, Doug, are there still any objections to commit the rest of v16?

Well, Andrew has been telling me privately that even the part that
was already committed regresses XenServer in some way.

Independent of that, Doug, can you confirm things work for you
with the remaining patches applied to current staging?

And of course patch 7 still needs looking at, which I didn't make a
priority because so far it looked like there'll be fixes needed anyway.

Hmmm... Andrew, could you provide more details?

OK, so, there is a question here: When is Xen 4.9 final call for this series?
Is it last posting date or hard code freeze?

Guys, tempus fugit. Andrew, could you post details about discovered issues?
Doug, is it OK for you to get the rest of my patches into master? Jan, could
you review the rest of v16 patches? I really, really, really, wish to see
this stuff in 4.9.

Everything in the right order please: I don't see much point in
reviewing that last remaining patch (which is not exactly small)
without first knowing what issues we have with the first part
as well as what issues people (read: Doug) have run into with
the rest (for this latter, from what I've read last there may be
none known at this time).
