The following patch is going to require TSYNC, which is only available
since libseccomp 2.2.0.
libseccomp 2.2.0 was released February 12, 2015.
According to repology, libseccomp version in different distros:
RHEL-7: 2.3.1
Debian (Stretch): 2.3.1
OpenSUSE Leap 15: 2.3.2
Ubuntu (Xenial): 2.3.1
This will drop support for -sandbox on:
Debian (Jessie): 2.1.1 (but 2.2.3 in backports)

After commit b3f1c8c413 "qemu-pr-helper: use new
libmultipath API", QEMU started using new libmultipath API, which is not
available on CentOS 7.x.
This fixes that by probing the new libmultipath API in configure. If it fails,
then try probing the old API. If it fails, then consider libmultipath not
available.
With this, configure script defines CONFIG_MPATH_NEW_API that is used in
scsi/qemu-pr-helper.c to use the new libmultipath API.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Add a pair of configure options --{enable,disable}-libpmem to control
whether QEMU is compiled with PMDK libpmem [1].
QEMU may write to the host persistent memory (e.g. in vNVDIMM label
emulation and live migration), so it must take the proper operations
to ensure the persistence of its own writes. Depending on the CPU
models and available instructions, the optimal operation can vary [2].
PMDK libpmem have already implemented those operations on multiple CPU
models (x86 and ARM) and the logic to select the optimal ones, so QEMU
can just use libpmem rather than re-implement them.
Libpem is a part of PMDK project(formerly known as NMVL).
The project's home page is: http://pmem.io/pmdk/
And the project's repository is: https://github.com/pmem/pmdk/
For more information about libpmem APIs, you can refer to the comments
in source code of: pmdk/src/libpmem/pmem.c, begin at line 33.

Per supported platforms doc[1], the various min glib on relevant distros is:
RHEL-7: 2.50.3
Debian (Stretch): 2.50.3
Debian (Jessie): 2.42.1
OpenBSD (Ports): 2.54.3
FreeBSD (Ports): 2.50.3
OpenSUSE Leap 15: 2.54.3
SLE12-SP2: 2.48.2
Ubuntu (Xenial): 2.48.0
macOS (Homebrew): 2.56.0
This suggests that a minimum glib of 2.42 is a reasonable target.
The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only
has glib 2.40.0, and this is needed for testing during merge. Thus an
exception is made to the documented platform support policy to allow for
all three current LTS releases to be supported.
Docker jobs that not longer satisfy this new min version are removed.

since we can directly know who took the lock then as long as we can have

The configure script outputs "yes" regardless which libfdt is used:
./configure
[...]
fdt support yes
Sometimes you can have both system and local git version available,
change the configure script to display which library got selected:
debian8$ dpkg-query --showformat='${Version}\n' --show libfdt-dev
1.4.0+dfsg-1
debian8$ ./configure
[...]

QEMU requires libfdt version >= 1.4.2.
If the host has an older libfdt installed, the configure script will use
a (git cloned) local version.
Example with Debian 8:
$ dpkg-query --showformat='${Version}\n' --show libfdt-dev
1.4.0+dfsg-1
$ ./configure
[...]
fdt support yes # from git submodule 'dtc'
If this case occurs, the linker will have 2 different libfdt available in
the library search path. The default behavior is to search the system path
first, then the local path.
Even if the configure script noticed the libfdt is too old and clone a more
recent locally, when linking the system library is selected first, and the
link process eventually fails:
LINK mips64el-softmmu/qemu-system-mips64el

QEMU already uses a kludge to enforce local CFLAGS before system ones for
libpixman and libfdt, add a similar kludge for the LDFLAGS to enforce using
the local libfdt.

While it was fixed in libcacard upstream (so that individual

This makes it much easier to find a particular thing in config.log.
We have to use the ${BASH_LINENO[*]} syntax which is a syntax error in
other shells, so test what shell we are running and use eval.
The extra output is only printed if configure is run with bash. On
systems where /bin/sh is not bash, it is necessary to say bash
./configure to get the extra debug info in the log.

Xen unstable (to be in 4.11) has two new dmops, relocate_memory and
pin_memory_cacheattr. Use these to set up the VGA memory, replacing the
previous calls to libxc. This allows the VGA console to work properly
when QEMU is running restricted (-xen-domid-restrict).
Wrapper functions are provided to allow QEMU to work with older versions
of Xen.
Tweak the error handling while making this change:
* Report pin_memory_cacheattr errors.
* Report errors even when DEBUG_HVM is not set. This is useful for
trying to understand why VGA is not working, since otherwise it just
fails silently.
* Fix the return values when an error occurs. The functions now
consistently return -1 and set errno.

configure tries to detect if the compiler

This program doesn't actually detect the problem
with GCC on RHEL7 on PPC64LE (Red Hat 4.8.5-28).
This patch updates the test to look more like

Our rule right now is to use <> for external headers,
"" for internal ones. The idea was to avoid conflicts
between e.g. a system file named <trace.h> and an
internal one by the same name.
Unfortunately we use -I compiler flag so it does not
help: a system file doing #include <trace.h> will
still pick up ours first.
To fix, switch to -iquote which is supported by both
gcc and clang and only affects #include "" directives.
As a side effect, this catches any future uses of
#include <> for internal headers.

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.

This patch disables the pragma diagnostic -Wunused-but-set-variable for
clang in util/coroutine-ucontext.c.
This in turn allows us to remove it from the configure check, so the
CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE will succeed for clang.
With that in place clang builds (linux) will use -Werror by default,
which breaks the build due to warning about unaligned struct members.
Just turning off this warning isn't a good idea as it indicates
portability problems. So make it a warning again, using
-Wno-error=address-of-packed-member. That way it doesn't break the
build but still shows up in the logs.
Now clang builds qemu without errors. Well, almost. There are some
left in the rdma code. Leaving that to the rdma people. All others can
use --disable-rdma to workarounds 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.

We dropped support for ia64 host CPUs in the 2.11 release (removing
the TCG backend for it, and advertising the support as being
completely removed in the changelog). However there are a few bits
and pieces of code still floating about. Remove those, too.
We can drop the check in configure for "ia64 or hppa host?"
entirely, because we don't support hppa hosts either any more.

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):

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.
