Kashyap Chamarthy c8945922be docs: pcie: Spell out machine type needs for PCIe features

 a 'Connection refused' during running, but still gives the correct exit

 it can't connect, so that's the right error).

Yoni Bettan d61a363d3e pci: removed the is_express field since a uniform interface was inserted
according to Eduardo Habkost's commit fd3b02c889 all PCIEs now implement
INTERFACE_PCIE_DEVICE so we don't need is_express field anymore.

Devices that implements only INTERFACE_PCIE_DEVICE (is_express == 1)
or
devices that implements only INTERFACE_CONVENTIONAL_PCI_DEVICE (is_express == 0)
where not affected by the change.

The only devices that were affected are those that are hybrid and also
had (is_express == 1) - therefor only:
  - hw/vfio/pci.c
  - hw/usb/hcd-xhci.c
  - hw/xen/xen_pt.c

For those 3 I made sure that QEMU_PCI_CAP_EXPRESS is on in instance_init()

Fam Zheng 4eb9956034 docs: Add docs/devel/testing.rst
To make our efforts on QEMU testing easier to consume by contributors,
let's add a document. For example, Patchew reports build errors on
patches that should be relatively easy to reproduce with a few steps, and
it is much nicer if there is such a documentation that it can refer to.

This focuses on how to run existing tests and how to write new test
cases, without going into the frameworks themselves.

The VM based testing section is moved from tests/vm/README which now
is a single line pointing to the new doc.

Haozhong Zhang cb836434cd nvdimm: add 'unarmed' option
Currently the only vNVDIMM backend can guarantee the guest write
persistence is device DAX on Linux, because no host-side kernel cache
is involved in the guest access to it. The approach to detect whether
the backend is device DAX needs to access sysfs, which may not work
with SELinux.

Instead, we add the 'unarmed' option to device 'nvdimm', so that users
or management utils, which have enough knowledge about the backend,
can control the unarmed flag in guest ACPI NFIT via this option. The
guest Linux NVDIMM driver, for example, will mark the corresponding
vNVDIMM device read-only if the unarmed flag in guest NFIT is set.

The default value of 'unarmed' option is 'off' in order to keep the
backwards compatibility.

Haozhong Zhang 9837684316 hostmem-file: add "align" option
When mmap(2) the backend files, QEMU uses the host page size
(getpagesize(2)) by default as the alignment of mapping address.
However, some backends may require alignments different than the page
size. For example, mmap a device DAX (e.g., /dev/dax0.0) on Linux
kernel 4.13 to an address, which is 4K-aligned but not 2M-aligned,
fails with a kernel message like

[617494.969768] dax dax0.0: qemu-system-x86: dax_mmap: fail, unaligned vma (0x7fa37c579000 - 0x7fa43c579000, 0x1fffff)

Because there is no common approach to get such alignment requirement,
we add the 'align' option to 'memory-backend-file', so that users or
management utils, which have enough knowledge about the backend, can
specify a proper alignment via this option.

Kashyap Chamarthy c117bb14ff QAPI & interop: Clarify events emitted by 'block-job-cancel'
When you cancel an in-progress 'mirror' job (or "active `block-commit`")
with QMP `block-job-cancel`, it emits the event: BLOCK_JOB_CANCELLED.
However, when `block-job-cancel` is issued *after* `drive-mirror` has
indicated (via the event BLOCK_JOB_READY) that the source and
destination have reached synchronization:

    [...] # Snip `drive-mirror` invocation & outputs
    {
      "execute":"block-job-cancel",
      "arguments":{
        "device":"virtio0"
      }
    }

    {"return": {}}

It (`block-job-cancel`) will counterintuitively emit the event
'BLOCK_JOB_COMPLETED':

    {
      "timestamp":{
        "seconds":1510678024,
        "microseconds":526240
      },
      "event":"BLOCK_JOB_COMPLETED",
      "data":{
        "device":"virtio0",
        "len":41126400,
        "offset":41126400,
        "speed":0,
        "type":"mirror"
      }
    }

But this is expected behaviour, where the _COMPLETED event indicates
that synchronization has successfully ended (and the destination now has
a point-in-time copy, which is at the time of cancel).

So add a small note to this effect in 'block-core.json'.  While at it,
also update the "Live disk synchronization -- drive-mirror and
blockdev-mirror" section in 'live-block-operations.rst'.

(Thanks: Max Reitz for reminding me of this caveat on IRC.)

Stefan Hajnoczi 1b3bbc6887 Use qemu.org domain name
The owner of qemu.org has delegated authority to modify DNS records to
the QEMU Project.  This has allowed us to use the domain name without
worries about IP address changes or technical issues disrupting service.
The issues described in commit 8593898109
("Use qemu-project.org domain name") have therefore been mitigated.

This patch switches back to consistently using qemu.org instead of
qemu-project.org in documentation, version.rc, and the Windows installer
script.

The git submodules and SeaBIOS still use qemu-project.org for the time
being.  This will be fixed in the QEMU 2.12 release cycle.

pc, pci, virtio: fixes, features

A bunch of fixes all over the place.
A new vmcore device - the user interface around it is still somewhat
controversial, but I feel most of the code is fine, suggestions can be
addressed by adding patches on top.

Dr. David Alan Gilbert 44b1ff319c migration: pre_save return int
Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.

Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.

Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

Stefan Hajnoczi 78aa8aa019 docs: add qemu-block-drivers(7) man page
Block driver documentation is available in qemu-doc.html.  It would be
convenient to have documentation for formats, protocols, and filter
drivers in a man page.

Extract the relevant part of qemu-doc.html into a new file called
docs/qemu-block-drivers.texi.  This file can also be built as a
stand-alone document (man, html, etc).
