Volker Rümelin 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.

Peter Maydell 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.

Denis Plotnikov 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
------------------------------------------------------------
real     65.5       16.3 (-75 %)    1.9          1.6 (-16 %)
user     65.0       15.8            5.3          2.5
sys       3.3        0.2            2.0          2.0

Both ZLIB and ZSTD gave the same compression ratio: 1.57
compressed image size in both cases: 1.4G

KONRAD Frederic 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:

(gdb) target remote localhost:7960

warning: Register "fp0" has an unsupported size (96 bits)

Peter Maydell 516e8b7d4a configure: Honour --disable-werror for Sphinx
If we are not making warnings fatal for compilation, make them
non-fatal when building the Sphinx documentation also.  (For instance
Sphinx 3.0 warns about some constructs that older versions were happy
with, which is a build failure if we use the warnings-as-errors
flag.)

This provides a workaround at least for LP:1872113.

Richard Henderson 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.

This adjustment was random and unnecessary.  The user mode

guest_base that allows the host qemu binary to not conflict

With modern distributions, this isn't even used, as the default
is PIE, which does the same job in a more portable way.

Alex Bennée a092a95547 configure: disable MTTCG for MIPS guests
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.

Eric Blake 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.

Richard Henderson 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.

Eduardo Habkost 67cf3f5cf5 Use -isystem for linux-headers dir
glibc and Linux-provided headers are known to generate macro
redefinition warnings when used together.  For example:
<linux/mman.h> and <sys/mman.h> duplicate some macro definitions.

We normally never see those warnings because GCC suppresses
warnings generated by system headers.  We carry our own copy of
Linux header files, though, and this makes those warnings not be
suppressed when glibc headers are included before Linux headers
(e.g. if <sys/mman.h> is included before <linux/mman.h>).

Use -isystem instead of -I for linux-headers.  This makes the
compiler treat our linux-headers directory the same way it treats
system-provided Linux headers, and suppress warnings generated by
them.

Philippe Mathieu-Daudé bd702ffc50 configure: Fix building with SASL on Windows
The Simple Authentication and Security Layer (SASL) library
re-defines the struct iovec on Win32 [*]. QEMU also re-defines
it in "qemu/osdep.h". The two definitions then clash on a MinGW
build.
We can avoid the SASL definition by defining STRUCT_IOVEC_DEFINED.
Since QEMU already defines 'struct iovec' if it is missing, add
the definition to vnc_sasl_cflags to avoid SASL re-defining it.

Christian Ehrhardt bd83c861c0 modules: load modules from versioned /var/run dir
On upgrades the old .so files usually are replaced. But on the other
hand since a qemu process represents a guest instance it is usually kept
around.

That makes late addition of dynamic features e.g. 'hot-attach of a ceph
disk' fail by trying to load a new version of e.f. block-rbd.so into an
old still running qemu binary.

This adds a fallback to also load modules from a versioned directory in the
temporary /var/run path. That way qemu is providing a way for packaging
to store modules of an upgraded qemu package as needed until the next reboot.

An example how that can then be used in packaging can be seen in:

Stefan Hajnoczi 73fd282e7b aio-posix: add io_uring fd monitoring implementation
The recent Linux io_uring API has several advantages over ppoll(2) and
epoll(2).  Details are given in the source code.

Add an io_uring implementation and make it the default on Linux.
Performance is the same as with epoll(7) but later patches add
optimizations that take advantage of io_uring.

It is necessary to change how aio_set_fd_handler() deals with deleting
AioHandlers since removing monitored file descriptors is asynchronous in
io_uring.  fdmon_io_uring_remove() marks the AioHandler deleted and
aio_set_fd_handler() will let it handle deletion in that case.

Kevin Wolf f353415ffd qemu-storage-daemon: Add barebone tool
This adds a new binary qemu-storage-daemon that doesn't yet do more than
some typical initialisation for tools and parsing the basic command
options --version, --help and --trace.

Even though this doesn't add any options yet that create things (like
--object or --blockdev), already document that we're planning to process
them in the order they are given on the command line rather than trying
(and failing, like vl.c) to resolve dependencies between options
automatically.
