67ab1ce926 qapi: Stop rejecting #optional
Commit 1d8bda1 got rid of #optional tags, and added a check to keep
them from getting added back, to make sure patches then in flight
don't add them back.  It's been six months, time to drop that check.

de6b4f908c qemu-options: Remove stray colons from output of --help
Commit 43f187a broke --help: it put colons into blank lines.  It
removed the colon from DEFHEADING(TITLE:) and added it back in the
macro expansion of DEFHEADING(TITLE), so hxtool can emit "@subsection
TITLE" more easily.  Trouble is it's added back even for the blank
lines made with DEFHEADING().

Put the colons back where they were before commit 43f187a, and strip
them in hxtool instead.

d36d0a9d15 dump-guest-memory.py: fix No symbol "vmcoreinfo_find"
When qemu is compiled without debug, the dump gdb python script can fail with:

Error occurred in Python command: No symbol "vmcoreinfo_find" in current context.

Because vmcoreinfo_find() is inlined and not exported.

Use the underlying object_resolve_path_type() to get the instance instead.

c1c4c2192c s390/kvm_virtio/linux-headers: remove traces of old virtio transport
We no longer support the old s390 transport, neither does the newest
Linux kernel. Remove it from the linux header script as well as the
s390x virtio code.  We still should handle the VIRTIO_NOTIFY hypercall,
to tolerate early printk on older guest kernels without an sclp console.
We continue to ignore these events.

70b7fba987 Use HTTPS for qemu.org and other domains
qemu.org enabled HTTPS in 2017 and it should be used instead of HTTP.
There are also URLs to json.org, openvpn.net, and other domains that
support HTTPS.

This patch updates the qemu.org domains everywhere and also third-party
domains that I have checked.

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.

d0dead3b6d scripts/make-release: ship u-boot source as a tarball
The u-boot sources we ship currently cause problems with unpacking on
a case-insensitive filesystem due to path conflicts. This has been
fixed in upstream u-boot via commit 610eec7f, but since it is not
yet included in an official release we implement this approach as a
temporary workaround.

Once we move to a u-boot containing commit 610eec7f we should revert
this patch.

49ad3cfa67 build: delay check for empty git submodule list
We short circuit the git submodule update when passed an empty module list.
This accidentally causes the 'status' command to write to the status file. The
test needs to be delayed into the individual commands to avoid this premature
writing of the status file.

37b5e74e28 build: don't fail if given a git submodule which does not exist
If going back in time in git history, across a commit that introduces a new
submodule, the 'git-submodule.sh' script will fail, causing rebuild to fail.

This is because config-host.mak contains a GIT_SUBMODULES variable that lists
a submodule that only exists in the later commit. config-host.mak won't get
repopulated until config.status is invoked, but make won't get this far due to
the submodule error.

This change makes 'git-submodule.sh' check whether each module is known to git
and drops any which are not present. A warning message will be printed when any
submodule is dropped in this manner.

f62bbee55d build: allow automatic git submodule updates to be disabled
Some people building QEMU use VPATH builds where the source directory is on a
read-only volume. In such a case 'scripts/git-submodules.sh update' will always
fail and users are required to run it manually themselves on their original
writable source directory.

While this is already supported, it is nice to give users a command line flag
to configure to permanently disable automatic submodule updates, as it means
they won't get hard to diagnose failures from git-submodules.sh at an arbitrary
later date.

This patch thus introduces a flag '--disable-git-update' which will prevent
'make' from ever running 'scripts/git-submodules.sh update'. It will still run
the 'status' command to determine if a submodule update is needed, but when it
does this it'll simply stop and print a message instructing the developer what
todo. eg

$ ./configure  --target-list=x86_64-softmmu --disable-git-update
...snip...

$ make
  GEN     config-host.h
  GEN     trace/generated-tcg-tracers.h
  GEN     trace/generated-helpers-wrappers.h
  GEN     trace/generated-helpers.h
  GEN     trace/generated-helpers.c
  GEN     module_block.h

GIT submodule checkout is out of date. Please run
  scripts/git-submodule.sh update ui/keycodemapdb

There are cases where users do VPATH builds with the source directory being on

927128222b ui: add keycodemapdb repository as a GIT submodule
The https://gitlab.com/keycodemap/keycodemapdb/ repo contains a
data file mapping between all the different scancode/keycode/keysym
sets that are known, and a tool to auto-generate lookup tables for
different combinations.

It is used by GTK-VNC, SPICE-GTK and libvirt for mapping keys.
Using it in QEMU will let us replace many hand written lookup
tables with auto-generated tables from a master data source,
reducing bugs. Adding new QKeyCodes will now only require the
master table to be updated, all ~20 other tables will be
automatically updated to follow.

47bb908dd1 docker: don't rely on submodules existing in the main checkout
When building the tarball to pass into the docker/vm test image,
the code relies on the git submodules being checked out in the
main checkout.

ie if the developer has not run 'git submodule update --init dtc'
many of the docker tests will fail due to the libfdt package not
being present in the test images. Patchew manually checks out the
dtc submodule in the main git checkout, but this is a bad idea.

When running tests we want to have a predictable set of submodules
included in the source that's tested. The build environment is
completely independent of the developers host OS, so the submodules
the developer has checked out should not be considered relevant for
the tests.

This changes the archive-source.sh script so that it clones the
current git checkout into a temporary directory, checks out a
fixed set of submodules, builds the tarball and finally removes
the temporary git clone.

aef45d51d1 build: automatically handle GIT submodule checkout for dtc
Currently if DTC is required by configure and not available in the host
OS install, we exit with an error message telling the user to checkout a
git submodule or install the library.

This introduces automatic handling of the git submodule checkout process
and enables it for dtc. This only runs if building from GIT, so users of
release tarballs still need the system library install. The current state
of the git checkout is stashed in .git-submodule-status, and a helper
program is used to determine if this state matches the desired submodule
state. A dependency against 'Makefile' ensures that the submodule state
is refreshed at the start of the build process

091776545f scripts: Remove debug parameter from QEMUMonitorProtocol
Use logging module for the QMP debug messages.  The only scripts
that set debug=True are iotests.py and guestperf/engine.py, and
they already call logging.basicConfig() to set up logging.

Scripts that don't configure logging are safe as long as they
don't need debugging output, because debug messages don't trigger
the "No handlers could be found for logger" message from the
Python logging module.

Scripts that already configure logging but don't use debug=True
(e.g. scripts/vm/basevm.py) will get QMP debugging enabled for
free.

3d5eecab4a Add --firmwarepath to configure
Add a firmware path config option to configure.  Multiple directories
are accepted, with the usual colon as separator.  Default value is
${prefix}/share/qemu-firmware.  The path is searched in addition to the
current search path (typically ${prefix}/share/qemu).

This prepares qemu for the planned split of the prebuilt firmware blobs
into a separate project.

Distributions can also use this to get rid of the firmware symlink farm
and add -- for example -- /usr/share/seabios to the firmware path
instead.

5810314e98 qemu.py: Call logging.basicConfig() automatically
Not all scripts using qemu.py configure the Python logging
module, and end up generating a "No handlers could be found for

To avoid requiring every script using qemu.py to configure
logging manually, call basicConfig() when creating a QEMUMachine
object.  This won't affect scripts that already set up logging,
but will ensure that scripts that don't configure logging keep
working.

8e1fe1753a scripts: let checkpatch.pl process an entire GIT branch
Currently before submitting a series, devs should run checkpatch.pl
across each patch to be submitted. This can be automated using a
command such as:

  git rebase -i master -x 'git show | ./scripts/checkpatch.pl -'

This is rather long winded to type, so this patch introduces a way
to tell checkpatch.pl to validate a series of GIT revisions.

There are now three modes it can operate in 1) check a patch 2) check a source
file, or 3) check a git branch.

If no flags are given, the mode is determined by checking the args passed to
the command. If the args contain a literal ".." it is treated as a GIT revision
list. If the args end in ".patch" or equal "-" it is treated as a patch file.
Otherwise it is treated as a source file.

This automatic guessing can be overridden using --[no-]patch --[no-]file or
--[no-]branch

For example to check a GIT revision list:

    $ ./scripts/checkpatch.pl master..
    total: 0 errors, 0 warnings, 297 lines checked

    b886d352a2bf58f0996471fb3991a138373a2957 has no obvious style problems and is ready for submission.
    total: 0 errors, 0 warnings, 182 lines checked

    2a731f9a9ce145e0e0df6d42dd2a3ce4dfc543fa has no obvious style problems and is ready for submission.
    total: 0 errors, 0 warnings, 102 lines checked

    11844169bcc0c8ed4449eb3744a69877ed329dd7 has no obvious style problems and is ready for submission.

If a genuine patch filename contains the characters '..' it is
possible to force interpretation of the arg as a patch

  $ ./scripts/checkpatch.pl --patch master..

will force it to load a patch file called "master..", or equivalently

  $ ./scripts/checkpatch.pl --no-branch master..

will simply turn off guessing of GIT revision lists.

4738b0a85a qemu.py: avoid writing to stdout/stderr
This module should not write directly to stdout/stderr. Instead, it
should either raise exceptions or just log the messages and let the
callers handle them and decide what to do. For example, scripts could
choose to send the log messages stderr or/and write them to a file if
verbose or debugging mode is enabled.

This patch replaces the writes to stderr by an exception in the
send_fd_scm() when _socket_scm_helper is not set or not present. In the
same method, the subprocess Popen will now redirect the stdout/stderr to
logging.debug instead of writing to system stderr. As consequence, since
the Popen.communicate() is now used (in order to get the stdout), the
further call to wait() became redundant and was replaced by
Popen.returncode.

The shutdown() message on negative exit code will now be logged
to logging.warn instead of written to system stderr.
