e8d81a61e1 qemu-iotests: convert pwd and $(pwd) to $PWD
POSIX requires $PWD to be reliable, and we expect all
shells used by qemu scripts to be relatively close to
POSIX.  Thus, it is smarter to avoid forking the pwd
executable for something that is already available in
the environment.

So replace it with the following:

sed -i 's/\(`pwd`\|\$(pwd)\)/$PWD/g' $(git grep -l pwd)

Then delete a pointless line assigning PWD to itself.

3995035395 configure: Use LINKS loop for all build tree symlinks
A few places in configure were doing ad-hoc calls to
the symlink function to set up symlinks from the build tree
back to the source tree. We have a loop that does this
already for all files and directories listed in the LINKS
environment variable; use that instead.

e29e5c6ee0 configure: Rename FILES variable to LINKS
The FILES variable is used to accumulate a list of things to symlink
from the source tree into the build tree.  These don't have to be
individual files; symlinking an entire directory of data files is
also fine.  Rename it to something less confusing before we add a few
directories to it.

Improve the comment to clarify what DIRS and LINKS do and why
it's not a good idea to add things to LINKS with wildcarding.

4b2ff65a1f tests: Move tests/hex-loader-check-data/ to tests/data/hex-loader/
Currently tests/hex-loader-check-data contains data files used
by the hexloader-test, and configure individually symlinks those
data files into the build directory using a wildcard.

Using a wildcard like this is a bad idea, because if a new
data file is added, nothing causes configure to be rerun,
and so no symlink is added for the new file. This can cause
tests to spuriously fail when they can't find their data.
Instead, it's better to symlink an entire directory of
data files. We already have such a directory: tests/data.

Move the data files from tests/hex-loader-check-data/ to
tests/data/hex-loader/, and remove the unnecessary symlinking.

438c78dab7 tests: Move tests/acpi-test-data/ to tests/data/acpi/
Currently tests/acpi-test-data contains data files used by the
bios-tables-test, and configure individually symlinks those
data files into the build directory using a wildcard.

Using a wildcard like this is a bad idea, because if a new
data file is added, nothing causes configure to be rerun,
and so no symlink is added for the new file. This can cause
tests to spuriously fail when they can't find their data.
Instead, it's better to symlink an entire directory of
data files. We already have such a directory: tests/data.

Move the data files from tests/acpi-test-data/ to
tests/data/acpi/, and remove the unnecessary symlinking.

We can remove entirely the note in rebuild-expected-aml.sh
about copying any new data files, because now they will
be in the source directory, not the build directory, and
no copying is required.

(We can't just change the existing tests/acpi-test-data/
to being a symlinked directory, because if we did that and
a developer switched git branches from one after that change
to one before it then configure would end up trashing all
the test files by making them symlinks to themselves.
Changing their path avoids this annoyance.)

76dc75ca54 build: rename CONFIG_QGA_NTDDDISK to CONFIG_QGA_NTDDSCSI
There was inconsistency between commits:

  50cbebb9a3 configure: add configure check for ntdddisk.h
  a3ef3b2272 qga: added bus type and disk location path

The first commit added #define CONFIG_QGA_NTDDDISK but the second commit
expected the name to be CONFIG_QGA_NTDDSCSI. As a result the code in
second patch was never used.

Renaming the option to CONFIG_QGA_NTDDSCSI to match the name of header
file that is being checked for.

86583a07c4 configure: Provide option to explicitly disable AVX2
The configure script detects if the compiler has AVX2 support and
automatically sets avx2_opt="yes" which in turn defines CONFIG_AVX2_OPT.
There is no way of explicitly overriding this setting so this commit adds
two command-line options: --enable-avx2 and --disable-avx2.

The default behaviour, when no option is specified, is to maintain the
current behaviour and enable AVX2 if the compiler supports it.

Per supported platforms doc[1], the various min GTK3 on relevant distros is:

  RHEL-7.0: 3.8.8
  RHEL-7.2: 3.14.13
  RHEL-7.4: 3.22.10

This suggests that a minimum GTK3 of 3.14.0 is a reasonable target,

89d85cde75 ui: remove support for GTK2 in favour of GTK3
GTK2 was deprecated in the 2.12.0 release with:

  commit b7715af2b3
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Tue Dec 12 11:34:40 2017 +0000

    ui: deprecate use of GTK 2.x in favour of 3.x series

    The GTK 3.0 release was made in Feb, 2011:

      https://blog.gtk.org/2011/02/10/gtk-3-0-released/

    That will soon be 7 years ago, which is enough time to consider
    the 3.x series widely supported.

    Thus we deprecate the GTK 2.x support, which will allow us to
    delete it in the last release of 2018. By this time, GTK 3.x
    will be almost 8 years old.

3fa2d384c2 contrib: add elf2dmp tool
elf2dmp is a converter from ELF dump (produced by 'dump-guest-memory') to
Windows MEMORY.DMP format (also know as 'Complete Memory Dump') which can be
opened in WinDbg.

This tool can help if VMCoreInfo device/driver is absent in Windows VM and
'dump-guest-memory -w' is not available but dump can be created in ELF format.

The tool works as follows:
1. Determine the system paging root looking at GS_BASE or KERNEL_GS_BASE
to locate the PRCB structure and finds the kernel CR3 nearby if QEMU CPU
state CR3 is not suitable.
2. Find an address within the kernel image by dereferencing the first
IDT entry and scans virtual memory upwards until the start of the
kernel.
3. Download a PDB matching the kernel from the Microsoft symbol store,
and figure out the layout of certain relevant structures necessary for
the dump.
4. Populate the corresponding structures in the memory image and create
the appropriate dump header.

e811da7fe2 configure: preserve various environment variables in config.status
The config.status script is auto-generated by configure upon
completion. The intention is that config.status can be later invoked by
the developer directly, or by make indirectly, to re-detect the same
environment that configure originally used.

The current config.status script, however, only contains a record of the
command line arguments to configure. Various environment variables have
an effect on what configure will find. In particular PKG_CONFIG_LIBDIR &
PKG_CONFIG_PATH vars will affect what libraries pkg-config finds. The
PATH var will affect what toolchain binaries and XXXX-config scripts are
found. The LD_LIBRARY_PATH var will affect what libraries are
found. Most commands have env variables that will override the name/path
of the default version configure finds.

All these key env variables should be recorded in the config.status script.

Autoconf would also preserve CFLAGS, LDFLAGS, LIBS, CPPFLAGS, but QEMU
deals with those differently, expecting extra flags to be set using
configure args, rather than env variables. At the end of the script we
also don't have the original values of those env vars, as we modify them
during configure.

72d277a70e display/edid: add edid generator to qemu.
EDID is a metadata format to describe monitors.  On physical hardware
the monitor has an eeprom with that data block which can be read over
i2c bus.

On a linux system you can usually find the EDID data block in
/sys/class/drm/$card/$connector/edid.  xorg ships a edid-decode utility
which you can use to turn the blob into readable form.

I think it would be a good idea to use EDID for virtual displays too.
Needs changes in both qemu and guest kms drivers.  This patch is the
first step, it adds an generator for EDID blobs to qemu.  Comes with a
qemu-edid test tool included.

With EDID we can pass more information to the guest.  Names and serial
numbers, so the guests display configuration has no boring "Unknown
Monitor".  List of video modes.  Display resolution, pretty important
in case we want add HiDPI support some day.

After commit b3f1c8c413 "qemu-pr-helper: use new

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

17824406fa configure: add libpmem support
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.

Opengl support brings up libdrm. But actually nothing uses this library
or includes any of its headers. Just remove checking for it from configure.

5c0ef67ac4 configure: add sanity check to catch builds from "git archive"
The "git archive" feature creates tarballs which are missing all
submodule content. GitHub unhelpfully provides users with "Download"
links that claim to give them valid source release tarballs. These
GitHub archives will not be buildable as they are created by the
"git archive" feature and so are missing content. The user gets
unhelpful messages from make such as:

  fatal error: ui/input-keymap-atset1-to-qcode.c: No such file or directory

By adding a sanity check we can give users an informative message about
what they've done wrong.

e7b3af8159 glib: bump min required glib library version to 2.40
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.

5c99fa375d cutils: Provide strchrnul
strchrnul is a GNU extension and thus unavailable on a number of targets.
In the review for a commit removing strchrnul from 9p, I was asked to
create a qemu_strchrnul helper to factor out this functionality.
Do so, and use it in a number of other places in the code base that inlined
the replacement pattern in a place where strchrnul could be used.

ba59fb778e QemuMutex: support --enable-debug-mutex
We have had some tracing tools for mutex but it's not easy to use them
for e.g. dead locks.  Let's provide "--enable-debug-mutex" parameter
when configure to allow QemuMutex to store the last owner that took
specific lock.  It will be easy to use this tool to debug deadlocks
since we can directly know who took the lock then as long as we can have
a debugger attached to the process.
