Daniel P. Berrangé 2544e9e4aa docs: add guidance on configuring CPU models for x86
With the recent set of CPU hardware vulnerabilities on x86, it is
increasingly difficult to understand which CPU configurations are
good to use and what flaws they might be vulnerable to.

This doc attempts to help management applications and administrators in
picking sensible CPU configuration on x86 hosts. It outlines which of
the named CPU models are good choices, and describes which extra CPU
flags should be enabled to allow the guest to mitigate hardware flaws.

Alex Bennée fe8bf5f629 build-system: add coverage-report target
This will build a coverage report under the current directory in
reports/coverage. At the users option a report can be generated by
directly invoking something like:

  make foo/bar/coverage-report.html

Alex Bennée 2b1f35b9a8 Revert "Makefile: Rename TARGET_DIRS to TARGET_LIST"
This reverts commit 208ecb3e1a. This was
causing problems by making DEF_TARGET_LIST pointless and having to
jump through hoops to build on mingw with a dully enabled config.
This includes a change to fix the per-guest TCG test probe which was
added after 208ecb3 and used TARGET_LIST.

Matthias Maier 0d6b93deee Revert commit d4e5ec877c
This commit removes the PYTHON_UTF8 workaround. The problem with setting

  LC_ALL= LANG=C LC_CTYPE=en_US.UTF-8

is that the en_US.UTF-8 locale might not be available. In this case
setting above locales results in build errors even though another UTF-8
locale was originally set [1]. The only stable way of fixing the
encoding problem is by specifying the encoding in Python, like the
previous commit does.

Thomas Huth 7e563bfb8a Polish the version strings containing the package version
Since commit 67a1de0d19 there is no space anymore between the
version number and the parentheses when running configure with
--with-pkgversion=foo :

 $ qemu-system-s390x --version
 QEMU emulator version 2.11.50(foo)

But the space is included when building without that option
when building from a git checkout:

 $ qemu-system-s390x --version
 QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty)

The same confusion exists with the "query-version" QMP command.
Let's fix this by introducing a proper QEMU_FULL_VERSION definition
that includes the space and parentheses, while the QEMU_PKGVERSION
should just cleanly contain the package version string itself.
Note that this also changes the behavior of the "query-version" QMP
command (the space and parentheses are not included there anymore),
but that's supposed to be OK since the strings there are not meant
to be parsed by other tools.

Markus Armbruster 112ed241f5 qapi: Empty out qapi-schema.json
The previous commit improved compile time by including less of the
generated QAPI headers.  This is impossible for stuff defined directly
in qapi-schema.json, because that ends up in headers that that pull in
everything.

Move everything but include directives from qapi-schema.json to new
sub-module qapi/misc.json, then include just the "misc" shard where
possible.

It's possible everywhere, except:

* monitor.c needs qmp-command.h to get qmp_init_marshal()

* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
  qapi-event.h to get enum QAPIEvent

Perhaps we'll get rid of those some other day.

Adding a type to qapi/migration.json now recompiles some 120 instead
of 2300 out of 5100 objects.

Markus Armbruster 252dc3105f qapi: Generate separate .h, .c for each module
Our qapi-schema.json is composed of modules connected by include
directives, but the generated code is monolithic all the same: one
qapi-types.h with all the types, one qapi-visit.h with all the
visitors, and so forth.  These monolithic headers get included all
over the place.  In my "build everything" tree, adding a QAPI type
recompiles about 4800 out of 5100 objects.

We wouldn't write such monolithic headers by hand.  It stands to
reason that we shouldn't generate them, either.

Split up generated qapi-types.h to mirror the schema's modular
structure: one header per module.  Name the main module's header
qapi-types.h, and sub-module D/B.json's header D/qapi-types-B.h.

Mirror the schema's includes in the headers, so that qapi-types.h gets
you everything exactly as before.  If you need less, you can include
one or more of the sub-module headers.  To be exploited shortly.

Split up qapi-types.c, qapi-visit.h, qapi-visit.c, qmp-commands.h,
qmp-commands.c, qapi-event.h, qapi-event.c the same way.
qmp-introspect.h, qmp-introspect.c and qapi.texi remain monolithic.

The split of qmp-commands.c duplicates static helper function
qmp_marshal_output_str() in qapi-commands-char.c and
qapi-commands-misc.c.  This happens when commands returning the same
type occur in multiple modules.  Not worth avoiding.

Since I'm going to rename qapi-event.[ch] to qapi-events.[ch], and
qmp-commands.[ch] to qapi-commands.[ch], name the shards that way
already, to reduce churn.  This requires temporary hacks in
commands.py and events.py.  Similarly, c_name() must temporarily
be taught to munge '/' in common.py.  They'll go away with the rename.

Markus Armbruster cdb6610ae4 qapi/types qapi/visit: Generate built-in stuff into separate files
Linking code from multiple separate QAPI schemata into the same
program is possible, but involves some weirdness around built-in
types:

* We generate code for built-in types into .c only with option
  --builtins.  The user is responsible for generating code for exactly
  one QAPI schema per program with --builtins.

* We generate code for built-in types into .h regardless of
  --builtins, but guarded by #ifndef QAPI_VISIT_BUILTIN.  Because all
  copies of this code are exactly the same, including any combination
  of these headers works.

Replace this contraption by something more conventional: generate code
for built-in types into their very own files: qapi-builtin-types.c,
qapi-builtin-visit.c, qapi-builtin-types.h, qapi-builtin-visit.h, but
only with --builtins.  Obey --output-dir, but ignore --prefix for
them.

Make qapi-types.h include qapi-builtin-types.h.  With multiple
schemata you now have multiple qapi-types.[ch], but only one
qapi-builtin-types.[ch].  Same for qapi-visit.[ch] and
qapi-builtin-visit.[ch].

Bonus: if all you need is built-in stuff, you can include a much
smaller header.  To be exploited shortly.

Whenever qapi-schema.json changes, we run six programs eleven times to

silly.  Replace the six programs by a single program that spits out

Daniel P. Berrange 8cc357b5a8 Revert "build-sys: silence make by default or V=0"
This reverts commit 42a77f1ce4.

The primary intention of this change was to silence messages
like

  make[1]: '/home/berrange/src/virt/qemu/capstone/libcapstone.a' is up to date.

which we get when calling make recursively with explicit
targets.

The problem is that this change affected every make target,
not merely the targets that triggered these "is up to date"
messages. As a result any targets that were not invoking
commands via "$(call quiet-command ...)" suddenly become
silent. This is particularly bad for "make install" which
now appears todo nothing.

Rather than go through every make rule and try to identify
places where we now need to explicitly print a message to
show work taking place, just revert the change.

To address the original problem of silencing "is up to date"
messages, we simply add --quiet to the SUBDIR_MAKEVARS
variable, so it only affects us on recursive make calls.

Daniel P. Berrange d4e5ec877c qapi: force a UTF-8 locale for running Python
Python2 did not validate locale correctness when reading input data, so
would happily read UTF-8 data in non-UTF-8 locales. Python3 is strict so
if you try to read UTF-8 data in the C locale, it will raise an error
for any UTF-8 bytes that aren't representable in 7-bit ascii encoding.
e.g.

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 54: ordinal not in range(128)
Traceback (most recent call last):
  File "/tmp/qemu-test/src/scripts/qapi-commands.py", line 317, in <module>
    schema = QAPISchema(input_file)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 1468, in __init__
    parser = QAPISchemaParser(open(fname, 'r'))
  File "/tmp/qemu-test/src/scripts/qapi.py", line 301, in __init__
    previously_included)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 348, in _include
    exprs_include = QAPISchemaParser(fobj, previously_included, info)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 271, in __init__
    self.src = fp.read()
  File "/usr/lib64/python3.5/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]

More background on this can be seen in

  https://www.python.org/dev/peps/pep-0538/

Many distros support a new C.UTF-8 locale that is like the C locale,
but with UTF-8 instead of 7-bit ASCII. That is not entirely portable
though. This patch thus sets the LANG to "C", but overrides LC_CTYPE
to be en_US.UTF-8 locale. This gets us pretty close to C.UTF-8, but
in a way that should be portable to everywhere QEMU builds.

This patch only forces UTF-8 for QAPI scripts, since that is the one
showing the immediate error under Python3 with C locale, but potentially
we ought to force this for all python scripts used in the build process.

 - Q_KEY_CODE_MENU was incorrectly mapped to the compose
   scancode (0x8d) and is now 0x91

Daniel P. Berrange 2ec78706d1 ui: convert GTK and SDL1 frontends to keycodemapdb
The x_keycode_to_pc_keycode and evdev_keycode_to_pc_keycode
tables are replaced with automatically generated tables.
In addition the X11 heuristics are improved to detect running
on XQuartz and XWin X11 servers, to activate the correct OS-X
and Win32 keycode maps.

Daniel P. Berrange ed7b2624f2 ui: convert the SDL2 frontend to keycodemapdb
The SDL2 scancodes are conveniently identical to the USB
scancodes. Replace the sdl2_scancode_to_qcode table with
an automatically generated table.

Missing entries in sdl2_scancode_to_qcode now fixed:

  - 0x32 -> Q_KEY_CODE_BACKSLASH
  - 0x66 -> Q_KEY_CODE_POWER
  - 0x67 -> Q_KEY_CODE_KP_EQUALS
  - 0x74 -> Q_KEY_CODE_OPEN
  - 0x77 -> Q_KEY_CODE_FRONT
  - 0x7f -> Q_KEY_CODE_AUDIOMUTE
  - 0x80 -> Q_KEY_CODE_VOLUMEUP
  - 0x81 -> Q_KEY_CODE_VOLUMEDOWN
  - 0x85 -> Q_KEY_CODE_KP_COMMA
  - 0x87 -> Q_KEY_CODE_RO
  - 0x89 -> Q_KEY_CODE_YEN
  - 0x8a -> Q_KEY_CODE_HENKAN
  - 0x93 -> Q_KEY_CODE_HIRAGANA
  - 0xe8 -> Q_KEY_CODE_AUDIOPLAY
  - 0xe9 -> Q_KEY_CODE_AUDIOSTOP
  - 0xea -> Q_KEY_CODE_AUDIOPREV
  - 0xeb -> Q_KEY_CODE_AUDIONEXT
  - 0xed -> Q_KEY_CODE_VOLUMEUP

  - 0xf3 -> Q_KEY_CODE_STOP
  - 0xf4 -> Q_KEY_CODE_FIND
  - 0xf8 -> Q_KEY_CODE_SLEEP
  - 0xfa -> Q_KEY_CODE_AC_REFRESH
  - 0xfb -> Q_KEY_CODE_CALCULATOR

And some mistakes corrected:

  - 0x65 -> Q_KEY_CODE_COMPOSE, not duplicating Q_KEY_CODE_MENU

Changpeng Liu 406d2aa2cc contrib/vhost-user-blk: introduce a vhost-user-blk sample application
This commit introduces a vhost-user-blk backend device, it uses UNIX
domain socket to communicate with QEMU. The vhost-user-blk sample
application should be used with QEMU vhost-user-blk-pci device.

To use it, complie with:
make vhost-user-blk

and start like this:
vhost-user-blk -b /dev/sdb -s /path/vhost.socket

Move generic make flags in MAKEFLAGS (SUBDIR_MAKEFLAGS is more qemu specific).

Use --quiet to silence make 'is up to date' message.

Philippe Mathieu-Daudé b98a3bae25 Makefile: use $(MAKE) variable
For some systems (i.e. FreeBSD) the default 'make' is not compatible with the
GNU extensions used by QEMU makefiles.

Calling the GNU make (gmake) works, however the help displayed refers to the
host 'make' and copy/paste leads to lot of unobvious errors:

  $ gmake check-help
  [...]
   make check                Run all tests

  $ make check
  make: "Makefile" line 28: Missing dependency operator
  make: "Makefile" line 37: Need an operator
  make: "Makefile" line 41: warning: duplicate script for target "git-submodule-update" ignored
  make: "rules.mak" line 70: warning: duplicate script for target "%.o" ignored
  make: Unknown modifier ' '
  make: Unclosed substitution for eval modules (= missing)
  make: "tests/Makefile.include" line 24: Variable/Value missing from "export"
  make: "tests/" line 1: warning: Zero byte read from file, skipping rest of line.
  make: "tests/" line 1: Need an operator
  make: "Makefile" line 660: warning: duplicate script for target "ifneq" ignored
  make: "Makefile" line 78: warning: using previous script for "ifneq" defined here
  make: Fatal errors encountered -- cannot continue

Using the $(MAKE) variable, the help displayed is consistent with the 'make'
program used.
