Thanks Peter, very helpful -- and err, sorry to land you more work than you
already had :-)
Would I contribute anything by also reviewing and/or testing the sus
mentioned patches? I can at least test the A10 and raspi if this helps...

Other users like alignment RMW will have different requirements, though
(requests touching the same sector), so make it dynamic.

But what IS valid? You need to document this in docs/qapi-code-gen.txt
at a bare minimum.
Previously, it was not possible to use wait_for_overlapping_requests()
between tracked_request_begin()/end() because it would wait for itself.
Ignore the current request in the overlap check and run more of the
bdrv_co_do_preadv/pwritev code with a BdrvTrackedRequest present.

It will allow to reuse field with different BUSes, reducing code duplication.
Field is intended fot replacing 'hotplug_qdev' field in PCIBus and also
will allow to avoid adding equivalent field to DimmBus with possiblitity
to refactor other BUSes to use it instead of custom field.

Dear All,
Hi,
I traverse qemu website, to find out some useful documents for learning qemu
basics, and concepts. But, all available documents require so in-depth
technical knowledge and no one found to be self-instructive.
I need a book or any other tutorial-like resources, to learn Qemu and its
