Actually enable the global memory barriers if supported by the OS.
Because only recent versions of Linux include the support, they
are disabled by default. Note that it also has to be disabled
for QEMU to run under Wine.
Before this patch, rcutorture reports 85 ns/read for my machine,
after the patch it reports 12.5 ns/read. On the other hand updates
go from 50 *micro*seconds to 20 *milli*seconds.

Since commit 67a1de0d195a 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.

This adds RISC-V into the build system enabling the following targets:
- riscv32-softmmu
- riscv64-softmmu
- riscv32-linux-user
- riscv64-linux-user
This adds defaults configs for RISC-V, enables the build for the RISC-V
CPU core, hardware, and Linux User Emulation. The 'qemu-binfmt-conf.sh'
script is updated to add the RISC-V ELF magic.
Expected checkpatch errors for consistency reasons:

Since 218bb57dd79d6843e0592c30a82ea8c1fddc74a5, the -fsanitize=address
check fails with:
config-temp/qemu-conf.c:3:20: error: integer overflow in expression [-Werror=overflow]

Interestingly, UBSAN check doesn't produce a compile time warning.
Use a test that doesn't have compile time warnings, and make it

not using "defined(_POSIX_C_SOURCE) && !defined(__sun__)". This

The grep command of busybox uses regex. This fails on binary data
(e.g. stops on every \0), so it does not identify the string
BiGeNdIaN in the test case big/little. Therefore, it assumes
that the architecture is little endian.

/basic/lifecycle: ==20781==WARNING: ASan doesn't fully support
makecontext/swapcontext functions and may produce false positives in
some cases!

(25446121472)
False positive error reports may follow
For details see https://github.com/google/sanitizers/issues/189
OK
After:
tests/test-coroutine -p /basic/lifecycle
/basic/lifecycle: ==21110==WARNING: ASan doesn't fully support
makecontext/swapcontext functions and may produce false positives in
some cases!
OK
A similar work would need to be done for sigaltstack & windows fibers
to have similar coverage. Since ucontext is preferred, I didn't bother
checking the other coroutine implementations for now.

completely removed in the changelog). However there are a few bits

When --enable-debug is turned on, configure doesn't set -O level, and
uses default compiler -O0 level, which is slow.
Instead, use -Og if supported by the compiler (optimize debugging
experience), or -O1 (keeps code somewhat debuggable and works around
compiler bugs).
Unfortunately, gcc has many false-positive maybe-uninitialized
errors with Og and O1 (f27 gcc 7.2.1 20170915):

There seems to be a long list of related bugs in upstream GCC, some of
them are being fixed very recently:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=24639
For now, let's workaround it by using Wno-maybe-uninitialized (gcc-only).

When linking qemu-ga under some configuration (when gthread-2.0.pc
doesn't have -pthread, as happening atm with meson build), you may
have this linking issue:
/usr/bin/ld: libqemuutil.a(qemu-thread-posix.o): undefined reference to symbol 'pthread_setname_np@@GLIBC_2.12'
/usr/lib64/libpthread.so.0: error adding symbols: DSO missing from command line
Make sure qemu-ga links with the pthread library, by adding correct
flags to libs_qga.
This is really a QEMU bug, because it's QEMU code that's using pthread
functions, and so we must explicitly link against pthreads. The bug
was just masked by the fact that often some pkg-config or another for
one of our dependencies will add -pthread to the link line anyway.

In commit c97d6d2cdf97ed we accidentally added code to configure
that uses '==' for string equality testing. This is a bashism --
the portable way to write this is '='.
This fixes the "Unexpected operator error" complaint produced
if the system /bin/sh is dash.

This file begins tracking the files that will be the code base for HVF
support in QEMU. This code base is part of Google's QEMU version of
their Android emulator, and can be found at
https://android.googlesource.com/platform/external/qemu/+/emu-master-dev
This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted
Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is
appropriately licensed under GPL v2-or-later, except for the code inside
x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel),
is licensed GPL v2-only.
This code base already implements a very great deal of functionality,
although Google's version removed from Vertuu's the support for APIC
page and hyperv-related stuff. According to the Android Emulator Release
Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now
enabled by default on macOS for 32-bit x86 images to improve performance
and macOS compatibility", although we better use with caution for, as the
same Revision warns us, "If you experience issues with it specifically,
please file a bug report...". The code hasn't seen much update in the
last 5 months, so I think that we can further develop the code with
occasional visiting Google's repository to see if there has been any
update.
On top of Google's code, the following changes were made:
- add code to the configure script to support the --enable-hvf argument.
If the OS is Darwin, it checks for presence of HVF in the system. The
patch also adds strings related to HVF in the file qemu-options.hx.
QEMU will only support the modern syntax style '-M accel=hvf' no enable
hvf; the legacy '-enable-hvf' will not be supported.
- fix styling issues
- add glue code to cpus.c
- move HVFX86EmulatorState field to CPUX86State, changing the
the emulation functions to have a parameter with signature 'CPUX86State *'
instead of 'CPUState *' so we don't have to get the 'env'.

Since there are some issues in memory alloc/free machenism
in glibc for little chunk memory, if Qemu frequently
alloc/free little chunk memory, the glibc doesn't alloc
little chunk memory from free list of glibc and still
allocate from OS, which make the heap size bigger and bigger.
This patch introduce malloc_trim(), which will free heap
memory when there is no rcu call during rcu thread loop.
malloc_trim() can be enabled/disabled by --enable-malloc-trim/
--disable-malloc-trim in the Qemu configure command. The
default malloc_trim() is enabled for libc.
Below are test results from smaps file.

Recent glibc added memfd_create in sys/mman.h. This conflicts with
the definition in util/memfd.c:
/builddir/build/BUILD/qemu-2.11.0-rc1/util/memfd.c:40:12: error: static declaration of memfd_create follows non-static declaration
Fix the configure test, and remove the sys/memfd.h inclusion since the
file actually does not exist---it is a typo in the memfd_create(2) man
page.

When executing 'configure' in a fresh QEMU clone, in a fresh
OS install running in a ppc64le host, this is the error
shown:
-----
../configure --enable-trace-backend=simple --enable-debug
--target-list=ppc64-softmmu
ERROR: Unsupported CPU = ppc64le, try --enable-tcg-interpreter
-----
This isn't true, ppc64le host CPU is supported. This happens because,
in a fresh install, we don't have a C compiler to autodetect
the $cpu variable to "ppc64".
This patch moves the CC available check up a bit, just before verifying
the host CPU. This ensures that we bail out with a $CC not available
error instead of unsupported CPU (the host CPU detection without
the compiler wouldn't work properly anyway). It also allows --help to
keep working without a C compiler. With this patch, in the same ppc64le
host without gcc:
$ ../configure --enable-trace-backend=simple --enable-debug
--target-list=ppc64-softmmu
ERROR: "cc" either does not exist or does not work
$ ../configure --help
Usage: configure [options]
Options: [defaults in brackets after descriptions]
Standard options:
--help print this message
--prefix=PREFIX install in PREFIX [/usr/local]
--interp-prefix=PREFIX where to find shared libraries, etc.

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

Some users can't run a bare 'git' command, due to need for a transparent
proxying solution such as 'tsocks'. This adds an argument to configure to
let users specify such a thing:
./configure --with-git="tsocks git"
The submodule script is also updated to give the user a hint about using this
flag, if we fail to checkout modules.

GCC 4.9 and newer stopped warning for missing braces around the
"universal" C zero initializer {0}. One such initializer sneaked
into scsi/qemu-pr-helper.c and is breaking the build with such
older GCC versions.
Detect the lack of support for the idiom, and disable the warning
in that case.
