Actually Jun 9 at 8AM California / 4PM UK doesn't work for some of you,
so it is either:
1) Jun 9 at 7AM California / 3PM UK
2) Jun 14 at 8AM California / 4PM UK
My preference is the first option because it is sooner but let me know

This patch adds basic support for configuring and assisting virtio-mmio
based virtio-disk backend (emulator) which is intended to run out of
Qemu and could be run in any domain.
Although the Virtio block device is quite different from traditional
Xen PV block device
From: Julien Grall
This patch introduces helpers to allocate Virtio MMIO params
(IRQ and memory region) and create specific device node in
the Guest device-tree with allocated params. In order to deal
with multiple Virtio devices, reserve corresponding ranges.
For now, we reserve 1MB for memory
From: Oleksandr Tyshchenko
Hello all.
The purpose of this patch series is to add missing virtio-mmio bits to Xen
toolstack on Arm.
The Virtio support for toolstack [1] was postponed as the main target was to
upstream IOREQ/DM
support on Arm in the first place. Now, we already have IOREQ

The get-fields.sh which generate all the include/compat/.xlat/*.h
headers is quite slow. It takes for example nearly 3 seconds to
generate platform.h on a recent machine, or 2.3 seconds for memory.h.
Since it's only text processing, rewriting the mix of shell/sed/python
into a single perl script
Now that the command line generating "xlat.h" is check on rebuild, the
header will be regenerated whenever the list of xlat headers changes
due to change in ".config". We don't need to force a regeneration for
every changes in ".config".

I would like to suggest to have the MISRA C meeting just before the
