cde9925362 configure: Fix the _BSD_SOURCE define for the Haiku build
The Haiku VM that we are going to add is using _BSD_SOURCE instead
of BSD_SOURCE (without initial underscore)... according to David
Carlier, the BSD_SOURCE without underscore was likely a typo, so
let's simply add the underscore there now.
This fixes the build failure with the bswapXX() macros not being
defined after including <endian.h>.

d88618f717 configure: mark vhost-user Linux-only
The vhost-user protocol uses the Linux eventfd feature and is typically
connected to Linux kvm.ko ioeventfd and irqfd file descriptors. The
protocol specification in docs/interop/vhost-user.rst does not describe
how platforms without eventfd support work.

The QEMU vhost-user devices compile on other POSIX host operating
systems because eventfd usage is abstracted in QEMU. The libvhost-user
programs in contrib/ do not compile but we failed to notice since they
are not built by default.

Make it clear that vhost-user is only supported on Linux for the time
being. If someone wishes to support it on other platforms then the
details can be added to vhost-user.rst and CI jobs can test the feature
to prevent bitrot.

e5e856c1eb meson: move vhost_user_blk_server to meson.build
The --enable/disable-vhost-user-blk-server options were implemented in
./configure. There has been confusion about them and part of the problem
is that the shell syntax used for setting the default value is not easy
to read. Move the option over to meson where the conditions are easier
to understand:

  have_vhost_user_blk_server = (targetos == 'linux')

  if get_option('vhost_user_blk_server').enabled()
      if targetos != 'linux'
          error('vhost_user_blk_server requires linux')
      endif
  elif get_option('vhost_user_blk_server').disabled() or not have_system
      have_vhost_user_blk_server = false
  endif

This patch does not change behavior.

bc15e44cb2 configure: introduce --enable-vhost-user-blk-server
Make it possible to compile out the vhost-user-blk server. It is enabled
by default on Linux.

Note that vhost-user-server.c depends on libvhost-user, which requires
CONFIG_LINUX. The CONFIG_VHOST_USER dependency was erroneous since that
option controls vhost-user frontends (previously known as "master") and
not device backends (previously known as "slave").

76346b6264 configure: Test that gio libs from pkg-config work
On some hosts (eg Ubuntu Bionic) pkg-config returns a set of
libraries for gio-2.0 which don't actually work when compiling
statically. (Specifically, the returned library string includes
-lmount, but not -lblkid which -lmount depends upon, so linking
fails due to missing symbols.)

Check that the libraries work, and don't enable gio if they don't,
in the same way we do for gnutls.

cece116c93 configure: add option for virtiofsd
Currently it is unknown whether virtiofsd will be built at
configuration time. It will be automatically built when dependency
is met. Also, required libraries are not clear.

To make this clear, add configure option --{enable,disable}-virtiofsd.
The default is the same as current (enabled if available) like many
other options. When --enable-virtiofsd is given and dependency is not
met, we get:

  ERROR: Problem encountered: virtiofsd requires libcap-ng-devel and seccomp-devel
or
  ERROR: Problem encountered: virtiofsd needs tools and vhost-user support

In addition, configuration summary now includes virtiofsd entry:

5c53015a48 build: add --enable/--disable-libudev
Initially, libudev detection was bundled with --enable-mpath because
qemu-pr-helper was the only user of libudev.  Recently however the USB
U2F emulation has also started using libudev, so add a separate
option.  This also allows 1) disabling libudev if desired for static
builds and 2) for non-static builds, requiring libudev even if
multipath support is undesirable.

The multipath test is adjusted, because it is now possible to enter it
with configurations that should fail, such as --static --enable-mpath
--disable-libudev.

09e93326e4 build: replace ninjatool with ninja
Now that the build is done entirely by Meson, there is no need
to keep the Makefile conversion.  Instead, we can ask Ninja about
the targets it exposes and forward them.

The main advantages are, from smallest to largest:

- reducing the possible namespace pollution within the Makefile

- removal of a relatively large Python program

- faster build because parsing Makefile.ninja is slower than
parsing build.ninja; and faster build after Meson runs because
we do not have to generate Makefile.ninja.

- tracking of command lines, which provides more accurate rebuilds

In addition the change removes the requirement for GNU make 3.82, which
was annoying on Mac, and avoids bugs on Windows due to ninjatool not
knowing how to convert Windows escapes to POSIX escapes.

e1c4269763 block: deprecate the sheepdog block driver
This thread from a little over a year ago:

  http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html

states that sheepdog is no longer actively developed. The only mentioned
users are some companies who are said to have it for legacy reasons with
plans to replace it by Ceph. There is talk about cutting out existing
features to turn it into a simple demo of how to write a distributed
block service. There is no evidence of anyone working on that idea:

  https://github.com/sheepdog/sheepdog/commits/master

No real commits to git since Jan 2018, and before then just some minor
technical debt cleanup.

There is essentially no activity on the mailing list aside from
patches to QEMU that get CC'd due to our MAINTAINERS entry.

Fedora packages for sheepdog failed to build from upstream source
because of the more strict linker that no longer merges duplicate
global symbols. Fedora patches it to add the missing "extern"
annotations and presumably other distros do to, but upstream source
remains broken.

There is only basic compile testing, no functional testing of the
driver.

Since there are no build pre-requisites the sheepdog driver is currently
enabled unconditionally. This would result in configure issuing a
deprecation warning by default for all users. Thus the configure default
is changed to disable it, requiring users to pass --enable-sheepdog to
build the driver.

0c3dd50eae configure: fix performance regression due to PIC objects
Because most files in QEMU are grouped into static libraries, Meson conservatively
compiles them with -fPIC.  This is overkill and produces slowdowns up to 20% on
some TCG tests.

As a stopgap measure, use the b_staticpic option to limit the slowdown to
--enable-pie.  https://github.com/mesonbuild/meson/pull/7760 will allow
us to use b_staticpic=false and let Meson do the right thing.

cb8baa7720 configure: don't enable ASLR for --enable-debug Windows builds
Unlike other OSs it is not possible for gdb to temporarily disable ASLR when
debugging executables on Windows which causes gdb to fail with memory access
errors when trying to debug QEMU.

Keep ASLR enabled by default on Windows via the --dynamicbase compiler flag
except for --enable-debug builds when there is a clear expectation that a
functioning gdb is expected at the cost of slightly less security.

47b30835e4 configure: consistently pass CFLAGS/CXXFLAGS/LDFLAGS to meson
Environment variables like CFLAGS are easy to accidentally change.  Meson
warns if that happens, but in a project with a lot of configuration that
is easy to lose.  It is also surprising behavior since meson caches -D
options and remembers those on reconfiguration (which we rely on,
since configure options become -D options).

By placing the user-provided CFLAGS, CXXFLAGS and LDFLAGS in the
cross file, we at least get consistent behavior.  These environment
variables are still ugly and not really recommended, but there are
distros that rely on them.  For the gory details, refer to
https://github.com/mesonbuild/meson/issues/4664.

5770e8afd6 configure: do not clobber environment CFLAGS/CXXFLAGS/LDFLAGS
If the CFLAGS, CXXFLAGS or LDFLAGS variables are present in the environment,
any modification made within the configure script is passed down to Meson.
This is particularly undesirable for the "-pie" option, since it overrides
"-shared" and thus messes up the linker flags for shared modules.

Using a separate variable therefore fixes the bug, while clarifying that
the scope of these CFLAGS is just the configure script.

We also do not need to pass those variables in config-host.mak; they
were only used for printing the summary now that all submodules are
built with handwritten Meson rules).  For now synthesize CFLAGS in the
configuration summary, the next patch will also pass them in a cleaner
way using the cross file.

8b18cdbfd6 capstone: Convert Makefile bits to meson bits
There are better ways to do this, e.g. meson cmake subproject,
but that requires cmake 3.7 and some of our CI environments
only provide cmake 3.5.

Nor can we add a meson.build file to capstone/, because the git
submodule would then always report "untracked files".  Fixing that
would require creating our own branch on the qemu git mirror, at
which point we could just as easily create a native meson subproject.

Instead, build the library via the main meson.build.

This improves the current state of affairs in that we will re-link
the qemu executables against a changed libcapstone.a, which we wouldn't
do before-hand.  In addition, the use of the configuration header file
instead of command-line -DEFINES means that we will rebuild the
capstone objects with changes to meson.build.

Now that the installation is relocatable, there is no need to compile a

Drop the "Program Files" path completely: it is only usable on English

"correct" path to the Program Files folder is recommended, and NSIS

4bad7c3b58 configure: rename QEMU_GA_MSI_ENABLED to CONFIG_QGA_MSI
The QEMU_GA_MSI_ENABLED config-host.mak variable is emitted by
./configure. meson.build actually checks for CONFIG_QGA_MSI_ENABLED:

  summary_info += {'QGA MSI support':   config_host.has_key('CONFIG_QGA_MSI_ENABLED')}

Rename QEMU_GA_MSI_ENABLED to CONFIG_QGA_MSI for consistency with
CONFIG_QGA_VSS. Also use 'y' instead of 'yes' for consistency.

This fixes the feature summary printed by meson.build.

82bf7ae84c target/arm: Remove KVM support for 32-bit Arm hosts
We deprecated the support for KVM on 32-bit Arm hosts in time
for release 5.0, which means that our deprecation policy allows
us to drop it in release 5.2. Remove the code.

To repeat the rationale from the deprecation note: the Linux
kernel dropped support for 32-bit Arm KVM hosts in 5.7.

Running 32-bit guests on a 64-bit Arm host remains supported.

directly or indirectly via declare_dependency.  Makefiles instead did
not propagate dependencies correctly from static libraries, for example.
Therefore, flags for dependencies need not be included in QEMU_CFLAGS.

46859d9398 crypto: fix build with gcrypt enabled
If nettle is disabled and gcrypt enabled, the compiler and linker flags
needed for gcrypt are not passed.

Gnutls was also not added as a dependancy when gcrypt is enabled.

Attempting to add the library dependencies at the same time as the
source dependencies is error prone, as there are alot of different
rules for picking which sources to use, and some of the source files
use code level conditionals intead. It is thus clearer to add the
library dependencies separately.

853b4baf30 configure: Add system = 'linux' for meson when cross-compiling
Meson needs the "system = xyz" line when cross-compiling. We are already
adding a "system = 'windows'" for the MinGW cross-compilation case here,
so let's add a "system = 'linux'" now for Linux hosts, too.

09db9b9db3 meson: fix keymaps without qemu-keymap
In case the qemu-keymap tool generating them is neither installed on the
system nor built from sources (due to xkbcommon not being available)
qemu will not find the keymaps when started directly from the build
tree,

This happens because commit ddcf607fa3 ("meson: drop keymaps symlink")
removed the symlink to the source tree, and the special handling for
install doesn't help in case we do not install qemu.

Lets fix that by simply copying over the file from the source tree as
fallback.

5fe4076562 configure: Fix atomic64 test for --enable-werror on macOS
When using --enable-werror for the macOS builders in the Cirrus-CI,
the atomic64 test is currently failing, and config.log shows a bunch
of error messages like this:

 config-temp/qemu-conf.c:6:7: error: implicit declaration of function
 '__atomic_load_8' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
  y = __atomic_load_8(&x, 0);
      ^
 config-temp/qemu-conf.c:6:7: error: this function declaration is not a
 prototype [-Werror,-Wstrict-prototypes]

Seems like these __atomic_*_8 functions are available in one of the
libraries there, so that the test links and passes there when not
using --enable-werror. But there does not seem to be a valid prototype
for them in any of the header files, so that the test fails when using
--enable-werror.

Fix it by using the "official" built-in functions instead (see e.g.
https://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html).
We are not using the *_8 variants in QEMU anyway.

d6092e085d linux-user: Add support for a group of btrfs ioctls used for subvolumes
This patch implements functionality of following ioctls:

BTRFS_IOC_SUBVOL_CREATE - Creating a btrfs subvolume

    Create a btrfs subvolume. The subvolume is created using the ioctl's
    third argument which represents a pointer to a following structure
    type:

    struct btrfs_ioctl_vol_args {
	__s64 fd;
	char name[BTRFS_PATH_NAME_MAX + 1];
    };

    Before calling this ioctl, the fields of this structure should be filled
    with aproppriate values. The fd field represents the file descriptor
    value of the subvolume and the name field represents the subvolume
    path.

BTRFS_IOC_SUBVOL_GETFLAGS - Getting subvolume flags

    Read the flags of the btrfs subvolume. The flags are read using
    the ioctl's third argument that is a pointer of __u64 (unsigned long).
    The third argument represents a bit mask that can be composed of following
    values:
    BTRFS_SUBVOL_RDONLY           (1ULL << 1)
    BTRFS_SUBVOL_QGROUP_INHERIT   (1ULL << 2)
    BTRFS_DEVICE_SPEC_BY_ID       (1ULL << 3)
    BTRFS_SUBVOL_SPEC_BY_ID       (1ULL << 4)

BTRFS_IOC_SUBVOL_SETFLAGS - Setting subvolume flags

    Set the flags of the btrfs subvolume. The flags are set using the
    ioctl's third argument that is a pointer of __u64 (unsigned long).
    The third argument represents a bit mask that can be composed of same
    values as in the case of previous ioctl (BTRFS_IOC_SUBVOL_GETFLAGS).

BTRFS_IOC_SUBVOL_GETINFO - Getting subvolume information

    Read information about the subvolume. The subvolume information is
    returned in the ioctl's third argument which represents a pointer to
    a following structure type:

    struct btrfs_ioctl_get_subvol_info_args {
	/* Id of this subvolume */
	__u64 treeid;

	/* Name of this subvolume, used to get the real name at mount point */
	char name[BTRFS_VOL_NAME_MAX + 1];

	/*
	 * Id of the subvolume which contains this subvolume.
	 * Zero for top-level subvolume or a deleted subvolume.
	 */
	__u64 parent_id;

	/*
	 * Inode number of the directory which contains this subvolume.
	 * Zero for top-level subvolume or a deleted subvolume
	 */
	__u64 dirid;

	/* Latest transaction id of this subvolume */
	__u64 generation;

	/* Flags of this subvolume */
	__u64 flags;

	/* UUID of this subvolume */
	__u8 uuid[BTRFS_UUID_SIZE];

	/*
	 * UUID of the subvolume of which this subvolume is a snapshot.
	 * All zero for a non-snapshot subvolume.
	 */
	__u8 parent_uuid[BTRFS_UUID_SIZE];

	/*
	 * UUID of the subvolume from which this subvolume was received.
	 * All zero for non-received subvolume.
	 */
	__u8 received_uuid[BTRFS_UUID_SIZE];

	/* Transaction id indicating when change/create/send/receive happened */
	__u64 ctransid;
	__u64 otransid;
	__u64 stransid;
	__u64 rtransid;
	/* Time corresponding to c/o/s/rtransid */
	struct btrfs_ioctl_timespec ctime;
	struct btrfs_ioctl_timespec otime;
	struct btrfs_ioctl_timespec stime;
	struct btrfs_ioctl_timespec rtime;

	/* Must be zero */
	__u64 reserved[8];
     };

     All of the fields of this structure are filled after the ioctl call.

Implementation notes:

    Ioctls BTRFS_IOC_SUBVOL_CREATE and BTRFS_IOC_SUBVOL_GETINFO have structure
    types as third arguments. That is the reason why a corresponding definition
    are added in file 'linux-user/syscall_types.h'.

    The line '#include <linux/btrfs.h>' is added in file 'linux-user/syscall.c' to
    recognise preprocessor definitions for these ioctls. Since the file "linux/btrfs.h"
    was added in the kernel version 3.9, it is enwrapped in an #ifdef statement
    with parameter CONFIG_BTRFS which is defined in 'configure' if the
    header file is present.

1ffb3bbb3c meson: move zlib detection to meson
Meson includes the same logic that tries to look for -lz if
pkg-config (and cmake) cannot find zlib.  The undocumented
--disable-zlib-test option becomes a no-op.

There is still an instance of "-lz" in the LIBS directory.
It will go away as soon as tests are converted to meson,
because the zlib dependency does not propagate from libblock.fa
to the Makefile-build unit tests.

b7612f45da meson: move pixman detection to meson
When pixman is not installed (or too old), but virglrenderer is available
and "configure" has been run with "--disable-system", the build currently
aborts when trying to compile vhost-user-gpu (since it requires pixman).

Let's skip the build of vhost-user-gpu when pixman is not installed or
too old.  Instead of adding CONFIG_PIXMAN, it is simpler to move the
detection to pixman.

c44a33e2fe configure: silence 'shift' error message in version_ge()
If there are less than 2 arguments in version_ge(), the second
'shift' prints this error:
    ../configure: line 232: shift: shift count out of range

As Eric suggested, we can use 'shift ${2:+2}' which works out to
'shift 2' if $2 is set, or 'shift' (implicitly shift 1) if $2
is not set.

e8f3bd71d8 meson: convert po/
Meson warns if xgettext is not found.  In the future we may want to add
a required argument to i18n.gettext(); in the meanwhile, I am adding a
--enable-gettext/--disable-gettext option and feature detection in
configure.  This preserves QEMU's default behavior of detecting system
features, without any warning, if neither --enable-* nor --disable-*
is requested.

using $(wildcard) is not reproducible in Meson and was also brittle; for
example some .rst.inc files were left out.  The next patch will introduce

3a30446aed meson: linux-user
The most interesting or most complicated part here is the syscall_nr.h
generators.  In order to keep the generation logic all in meson.build,
I am adding to config_target the name of the .tbl file, and making the
generated file syscall<SUFFIX>_nr.h for input file syscall<SUFFIX>.tbl.

For architectures where the input file is not named syscall_nr.tbl,
syscall_nr.h has to be a source file; it's just a forwarder for x86
(i386/x86_64), while for MIPS64 it chooses between N32 and N64 ABIs.

a81df1b68b libqemuutil, qapi, trace: convert to meson
This shows how to do some "computations" in meson.build using its array
and dictionary data structures, and also a basic usage of the sourceset
module for conditional compilation.

Notice the new "if have_system" part of util/meson.build, which fixes
a bug in the old build system was buggy: util/dbus.c was built even for
non-softmmu builds, but the dependency on -lgio was lost when the linking
was done through libqemuutil.a.  Because all of its users required gio
otherwise, the bug was hidden.  Meson instead propagates libqemuutil's
dependencies down to its users, and shows the problem.

dedad02720 configure: add support for pseudo-"in source tree" builds
Meson requires the build dir to be separate from the source tree. Many
people are used to just running "./configure && make" though and the
meson conversion breaks that.

This introduces some backcompat support to make it appear as if an
"in source tree" build is being done, but with the results in the
"build/" directory. This allows "./configure && make" to work as it
did historically, albeit with the output binaries staying under build/.

added to --enable-sanitizers, it might be impossible to build with both
--enable-sanitizers and --enable-fuzzing, since not all sanitizers are
compatible with libFuzzer. In that case, we could enable ASAN with
--extra-cflags="-fsanitize=address"

2a4b472c3c osdep.h: Always include <sys/signal.h> if it exists
Regularize our handling of <sys/signal.h>: currently we include it in
osdep.h, but only for OpenBSD, and we include it without an ifdef
guard in a couple of C files.  This causes problems for Haiku, which
doesn't have that header.

Instead, check in configure whether sys/signal.h exists, and if it
does then always include it from osdep.h.

195588ccd5 build: Check that mlockall() exists
Instead of assuming that all POSIX platforms provide mlockall(),
test for it in configure. If the host doesn't provide this platform
then os_mlock() will fail -ENOSYS, as it does already on Windows.

This is necessary for Haiku, which does not have mlockall().

c9c8b88f0b util/qemu-openpty.c: Don't assume pty.h is glibc-only
Instead of using an OS-specific ifdef test to select the "openpty()
is in pty.h" codepath, make configure check for the existence of
the header and use the new CONFIG_PTY instead.

This is necessary to build on Haiku, which also provides openpty()
via pty.h.

7aa12aa215 Remove the CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE switch
GCC supports "#pragma GCC diagnostic" since version 4.6, and
Clang seems to support it, too, since its early versions 3.x.
That means that our minimum required compiler versions all support
this pragma already and we can remove the test from configure and
all the related #ifdefs in the code.

vhost-user. The above patch provides a generic device for vDPA purpose,
this vDPA device exposes to user space a non-vendor-specific configuration
interface for setting up a vhost HW accelerator, this patch set introduces
a third vhost backend called vhost-vdpa based on the vDPA interface.

Vhost-vdpa usage:

9df8b20d16 configure / util: Auto-detect the availability of openpty()
Recent versions of Solaris (v11.4) now feature an openpty() function,
too, causing a build failure since we ship our own implementation of
openpty() for Solaris in util/qemu-openpty.c so far. Since there are
now both variants available in the wild, with and without this function
(and illumos is said to not have this function yet), let's introduce a
proper HAVE_OPENPTY define for this to fix the build failure.

21b2eca6fc configure: add libdaxctl support
Add a pair of configure options --{enable,disable}-libdaxctl to control
whether QEMU is compiled with libdaxctl [1]. Libdaxctl is a utility
library for managing the device dax subsystem.

QEMU uses mmap(2) to maps vNVDIMM backends and aligns the mapping
address to the page size (getpagesize(2)) by default. However, some
types of backends may require an alignment different than the page
size. The 'align' option is provided to memory-backend-file to allow
users to specify the proper alignment.

For device dax (e.g., /dev/dax0.0), the 'align' option needs to match
the alignment requirement of the device dax, which can be fetched
through the APIs of libdaxctl version 57 or up.

[1] Libdaxctl is a part of ndctl project.
The project's repository is: https://github.com/pmem/ndctl

For more information about libdaxctl APIs, you can refer to the
comments in source code of: pmem/ndctl/daxctl/lib/libdaxctl.c.

1e4f6065da configure: add flags to support SafeStack
This patch adds a flag to enable/disable the SafeStack instrumentation
provided by LLVM.

On enable, make sure that the compiler supports the flags, and that we
are using the proper coroutine implementation (coroutine-ucontext).
On disable, explicitly disable the option if it was enabled by default.

While SafeStack is supported only on Linux, NetBSD, FreeBSD and macOS,
we are not checking for the O.S. since this is already done by LLVM.

bac8d222a1 configure: Add -Wno-psabi
On aarch64, gcc 9.3 is generating

qemu/exec.c: In function ‘address_space_translate_iommu’:
qemu/exec.c:431:28: note: parameter passing for argument of type \
  ‘MemTxAttrs’ {aka ‘struct MemTxAttrs’} changed in GCC 9.1

and many other repetitions.  This structure, and the functions
amongst which it is passed, are not part of a QEMU public API.
Therefore we do not care how the compiler passes the argument,
so long as the compiler is self-consistent.

The only portion of QEMU which does have a public api, and so
must have a stable abi, is "qemu/plugin.h".  We test this by
forcing -Wpsabi in tests/plugin/Makefile.

0aebab04b9 configure: add --enable-tsan flag + fiber annotations for coroutine-ucontext
We tried running QEMU under tsan in 2016, but tsan's lack of support for
longjmp-based fibers was a blocker:
  https://groups.google.com/forum/#!topic/thread-sanitizer/se0YuzfWazw

Fortunately, thread sanitizer gained fiber support in early 2019:
  https://reviews.llvm.org/D54889

This patch brings tsan support upstream by importing the patch that annotated
QEMU's coroutines as tsan fibers in Android's QEMU fork:
  https://android-review.googlesource.com/c/platform/external/qemu/+/844675

SLOF is required for building the s390-ccw firmware on s390x, since

5fe97d8829 virtio: add vhost-user-vsock base device
This patch introduces a vhost-user device for vsock, using the
vhost-vsock-common parent class.

The vhost-user-vsock device can be used to implement the virtio-vsock
device emulation in user-space.

7b23d121f9 ui: increase min required GTK version to 3.22.0
Based on a mail on the qemu-devel mailing list at
https://lists.nongnu.org/archive/html/qemu-devel/2020-05/msg02909.html
and some internet research the GTK3 versions on supported
platforms are:

    RHEL-7.4: 3.22.10
    RHEL-7.5: 3.22.26
    Debian (Stretch): 3.22.11
    Debian (Buster): 3.24.5
    OpenBSD (Ports): 3.22.30
    FreeBSD (Ports): 3.22.29
    OpenSUSE Leap 15: 3.22.30
    SLE12-SP2: Unknown
    SLE15: 3.22.30
    Ubuntu (Bionic): 3.22.30
    Ubuntu (Focal): 3.24.18
    macOS (Homebrew): 3.22.30

This justifies increasing the minimum required GTK version in
QEMU to 3.22.0.

c888f7e0fd target/arm: Use correct GDB XML for M-profile cores
GDB's remote protocol requires M-profile cores to use the feature
name 'org.gnu.gdb.arm.m-profile' instead of the 'org.gnu.gdb.arm.core'
feature used for A- and R-profile cores. We weren't doing this, which
meant GDB treated our M-profile cores like A-profile ones. This mostly
doesn't matter, but for instance means that it doesn't correctly
handle backtraces where an M-profile exception frame is involved.

Ship a copy of GDB's arm-m-profile.xml and use it on the M-profile
cores.  The integer registers have the same offsets as the
arm-core.xml, but register 25 is the M-profile XPSR rather than the
A-profile CPSR, so we need to update arm_cpu_gdb_read_register() and
arm_cpu_gdb_write_register() to handle XSPR reads and writes.

d298ac10ad qcow2: add zstd cluster compression
zstd significantly reduces cluster compression time.
It provides better compression performance maintaining
the same level of the compression ratio in comparison with
zlib, which, at the moment, is the only compression
method available.

The performance test results:
Test compresses and decompresses qemu qcow2 image with just
installed rhel-7.6 guest.
Image cluster size: 64K. Image on disk size: 2.2G

The test was conducted with brd disk to reduce the influence
of disk subsystem to the test results.
The results is given in seconds.

compress cmd:
  time ./qemu-img convert -O qcow2 -c -o compression_type=[zlib|zstd]
                  src.img [zlib|zstd]_compressed.img
decompress cmd
  time ./qemu-img convert -O qcow2
                  [zlib|zstd]_compressed.img uncompressed.img

           compression               decompression
         zlib       zstd           zlib         zstd
------------------------------------------------------------

sys       3.3        0.2            2.0          2.0

a976ed3ffd target/m68k: fix gdb for m68xxx
Currently "cf-core.xml" is sent to GDB when using any m68k flavor.  Thing is
it uses the "org.gnu.gdb.coldfire.core" feature name and gdb 8.3 then expects
a coldfire FPU instead of the default m68881 FPU.

This is not OK because the m68881 floats registers are 96 bits wide so it
crashes GDB with the following error message:

d2cd29e307 configure: Do not force pie=no for non-x86
PIE is supported on many other hosts besides x86.

The default for non-x86 is now the same as x86: pie is used
if supported, and may be forced via --enable/--disable-pie.

The original commit (40d6444e91) said:

  "Non-x86 are not changed, as they require TCG changes"

but I think that's wrong -- there's nothing about PIE that
affects TCG one way or another.

Tested on aarch64 (bionic) and ppc64le (centos 7) hosts.

While debugging check-acceptance failures I found an instability in
the mips64el test case. Briefly the test case:

  retry.py -n 100 -c -- ./mips64el-softmmu/qemu-system-mips64el \
    -display none -vga none -serial mon:stdio \
    -machine malta -kernel ./vmlinux-4.7.0-rc1.I6400 \
    -cpu I6400 -smp 8 -vga std \
    -append "printk.time=0 clocksource=GIC console=tty0 console=ttyS0 panic=-1" \
    --no-reboot

Reports about a 9% failure rate:

  Results summary:
  0: 91 times (91.00%), avg time 5.547 (0.45 varience/0.67 deviation)
  -6: 9 times (9.00%), avg time 3.394 (0.02 varience/0.13 deviation)
  Ran command 100 times, 91 passes

When re-run with "--accel tcg,thread=single" the instability goes
away.

  Results summary:
  0: 100 times (100.00%), avg time 17.318 (249.76 varience/15.80 deviation)
  Ran command 100 times, 100 passes

Which seems to indicate there is some aspect of the MIPS MTTCG fixes
that has been missed. Ideally we would fix that but I'm afraid I don't
have time to investigate and am not super familiar with the
architecture anyway. In lieu of someone tracking down the failure lets
disable it for now.

91e5998f18 linux-user, configure: fix (again) syscall_nr.h dependencies cleanup
This patch fixes two problems:
- it cleanups linux-user variants (for instance ppc64-linux-user
  and ppc64le-linux-user)
- it removes the .o file when it removes the .d file, otherwise the .o
  file is never updated

Fixes: 5f29856b85 ("linux-user, configure: improve syscall_nr.h dependencies checking")

5f29856b85 linux-user, configure: improve syscall_nr.h dependencies checking
This is mostly a fix for in-tree build.

It removes errors on .d directories:

  grep: ./.gitlab-ci.d: Is a directory
  grep: ./scripts/qemu-guest-agent/fsfreeze-hook.d: Is a directory

and improves performance by only checking <ARCH>-linux-user directories.

9bda600b08 build: Silence clang warning on older glib autoptr usage
glib's G_DEFINE_AUTOPTR_CLEANUP_FUNC() macro defines several static
inline functions, often with some of them unused, but prior to 2.57.2
did not mark the functions as such.  As a result, clang (but not gcc)
fails to build with older glib unless -Wno-unused-function is enabled.

43d1ccd2a0 tcg: Remove CONFIG_VECTOR16
The comment in tcg-runtime-gvec.c about CONFIG_VECTOR16 says that
tcg-op-gvec.c has eliminated size 8 vectors, and only passes on
multiples of 16.  This may have been true of the first few operations,
but is not true of all operations.

In particular, multiply, shift by scalar, and compare of 8- and 16-bit
elements are not expanded inline if host vector operations are not
supported.

For an x86_64 host that does not support AVX, this means that we will
fall back to the helper, which will attempt to use SSE instructions,
which will SEGV on an invalid 8-byte aligned memory operation.

This patch simply removes the CONFIG_VECTOR16 code and configuration
without further simplification.
