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.

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.

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.

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

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
scsi/qemu-pr-helper.c to use the new libmultipath API.

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.
