4034159c1a Revert "hw/virtio: Add support for VDPA network simulation devices"
This reverts commit cd341fd1ff.

The patch adds non-upstream code in
include/standard-headers/linux/virtio_pci.h
which would make maintainance harder.

Revert for now.

8e0b21e375 MAINTAINERS: Adjust migration documentation files
Commit 8cb2f8b172 ("docs/migration: Create migration/ directory")
changed migration documentation file structure but forgot to update the
entries in the MAINTAINERS file.

Commit 4c6f8a79ae ("docs/migration: Split 'dirty limit'") extracted
dirty limit documentation to a new file without updating dirty limit
section in MAINTAINERS file.

Fix the above.

Documentation on how to run Linux on the amigaone, pegasos2 and
sam460ex machines is currently buried in the depths of the qemu-devel
mailing list and in the source code. Let's collect the information in
the QEMU handbook for a one stop solution.

4cbb1513a2 hw/gpio: introduce pcf8574 driver
NXP PCF8574 and compatible ICs are simple I2C GPIO expanders.
PCF8574 incorporates quasi-bidirectional IO, and simple
communication protocol, when IO read is I2C byte read, and
IO write is I2C byte write. User can think of it as
open-drain port, when line high state is input and line low
state is output.

1cdcfb6e93 hw/gpio: Implement STM32L4x5 GPIO
Features supported :
- the 8 STM32L4x5 GPIOs are initialized with their reset values
    (except IDR, see below)
- input mode : setting a pin in input mode "externally" (using input
    irqs) results in an out irq (transmitted to SYSCFG)
- output mode : setting a bit in ODR sets the corresponding out irq
    (if this line is configured in output mode)
- pull-up, pull-down
- push-pull, open-drain

Difference with the real GPIOs :
- Alternate Function and Analog mode aren't implemented :
    pins in AF/Analog behave like pins in input mode
- floating pins stay at their last value
- register IDR reset values differ from the real one :
    values are coherent with the other registers reset values
    and the fact that AF/Analog modes aren't implemented
- setting I/O output speed isn't supported
- locking port bits isn't supported
- ADC function isn't supported
- GPIOH has 16 pins instead of 2 pins
- writing to registers LCKR, AFRL, AFRH and ASCR is ineffective

4c046ce37a hw/core: Add ResetContainer which holds objects implementing Resettable
Implement a ResetContainer.  This is a subclass of Object, and it
implements the Resettable interface.  The container holds a list of
arbitrary other objects which implement Resettable, and when the
container is reset, all the objects it contains are also reset.

This will allow us to have a 3-phase-reset equivalent of the old
qemu_register_reset() API: we will have a single "simulation reset"
top level ResetContainer, and objects in it are the equivalent of the
old QEMUResetHandler functions.

The qemu_register_reset() API manages its list of callbacks using a
QTAILQ, but here we use a GPtrArray for our list of Resettable
children: we expect the "remove" operation (which will need to do an
iteration through the list) to be fairly uncommon, and we get simpler
code with fewer memory allocations.

Since there is currently no listed owner in MAINTAINERS for the
existing reset-related source files, create a new section for
them, and add these new files there also.

c9cb496710 tests/avocado: ppc add hypervisor tests
The powernv and pseries machines both provide hypervisor facilities
that are supported by KVM. This is a large and complicated set of
features that don't get much system-level testing in ppc tests.

Add a new test case for these which runs QEMU KVM inside the target.
This downloads an Alpine VM image, boots it and downloads and installs
the qemu package, then boots a virtual machine under it, re-using the
original Alpine VM image.

273a70ae82 hw/arm/mps3r: Initial skeleton for mps3-an536 board
The AN536 is another FPGA image for the MPS3 development board. Unlike
the existing FPGA images we already model, this board uses a Cortex-R
family CPU, and it does not use any equivalent to the M-profile
"Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c.
It's therefore more convenient for us to model it as a completely
separate C file.

This commit adds the basic skeleton of the board model, and the
code to create all the RAM and ROM. We assume that we're probably
going to want to add more images in future, so use the same
base class/subclass setup that mps2-tz.c uses, even though at
the moment there's only a single subclass.

Following commits will add the CPUs and the peripherals.

e8058c6d65 MAINTAINERS: Drop myself as VT-d maintainers
Due to my own limitation on bandwidth, I noticed that unfortunately I won't
have time to review VT-d patches at least in the near future.  Meanwhile I
expect a lot of possibilities could actually happen in this area in the
near future.

To reflect that reality, I decided to drop myself from the VT-d role.  It
shouldn't affect much since we still have Jason around like usual, and
Michael on top.  But I assume it'll always be good if anyone would like to
fill this role up.

I'll still work on QEMU.  So I suppose anyone can still copy me if one
thinks essential.

vhost-user-input is in the input folder.  On the other hand, the folder
'hw/virtio' maintains other virtio stubs (e.g. I2C, RNG, GPIO, etc).

This patch moves vhost-user-input into the virtio folder for better code
organization.  No functionality change.

d95f260aee docs/devel/docs: Document .hx file syntax
We don't currently document the syntax of .hx files anywhere
except in a few comments at the top of individual .hx files.
We don't even have somewhere in the developer docs where we
could do this.

Add a new files docs/devel/docs.rst which can be a place to
document how our docs build process works. For the moment,
put in only a brief introductory paragraph and the documentation
of the .hx files. We could later add to this file by for
example describing how the QAPI-schema-to-docs process works,
or anything else that developers might need to know about
how to add documentation.

Make the .hx files refer to this doc file, and clean
up their header comments to be more accurate for the
usage in each file and less cut-n-pasted.
