The usb-host code has been rewritten for qemu 1.5 to use libusb,
the old code has been left in as temporary fallback.  Now we are
two releases further out, targeting the 1.7 release.  No major

Stefan Hajnoczi 70c60c089f coroutine: add ./configure --disable-coroutine-pool
The 'gthread' coroutine backend was written before the freelist (aka
pool) existed in qemu-coroutine.c.

This means that every thread is expected to exit when its coroutine
terminates.  It is not possible to reuse threads from a pool.

This patch automatically disables the pool when 'gthread' is used.  This
allows the 'gthread' backend to work again (for example,
tests/test-coroutine completes successfully instead of hanging).

I considered implementing thread reuse but I don't want quirks like CPU
affinity differences due to coroutine threads being recycled.  The
'gthread' backend is a reference backend and it's therefore okay to skip
the pool optimization.

Note this patch also makes it easy to toggle the pool for benchmarking
purposes:

  ./configure --with-coroutine-backend=ucontext \
              --disable-coroutine-pool

Tomoki Sekiyama b39297aedf qemu-ga: Add Windows VSS provider and requester as DLL
Adds VSS provider and requester as a qga-vss.dll, which is loaded by
Windows VSS service as well as by qemu-ga.

"provider.cpp" implements a basic stub of a software VSS provider.
Currently, this module only relays a frozen event from VSS service to the
agent, and thaw event from the agent to VSS service, to block VSS process
to keep the system frozen while snapshots are taken at the host.

To register the provider to the guest system as COM+ application, the type
library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl),
VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also
adds pre-compiled .tlb file in the repository in order to enable
cross-compile qemu-ga.exe for Windows with VSS support.

"requester.cpp" provides the VSS requester to kick the VSS snapshot process.
Qemu-ga.exe works without the DLL, although fsfreeze features are disabled.

These functions are only supported in Windows 2003 or later. In older
systems, fsfreeze features are disabled.

In several versions of Windows which don't support attribute
VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error
VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error.
To solve this fundamentally, we need a framework to handle mount writable
snapshot on guests, which is required by VSS auto-recovery feature
(cleanup phase after a snapshot is taken).

Tomoki Sekiyama d9840e2592 qemu-ga: Add configure options to specify path to Windows/VSS SDK
To enable VSS support in qemu-ga for Windows, header files included in
VSS SDK are required.
The VSS support is enabled by the configure option like below:
  ./configure --with-vss-sdk="/path/to/VSS SDK"

If the path is omitted, it tries to search the headers from default paths
and VSS support is enabled only if the SDK is found.
VSS support is disabled if --without-vss-sdk or --with-vss-sdk=no is
specified.

VSS SDK is available from:
  http://www.microsoft.com/en-us/download/details.aspx?id=23490

To cross-compile using mingw, you need to setup the SDK on Windows
environments to extract headers. You can also extract the SDK headers on
POSIX environments using scripts/extract-vss-headers and msitools.

In addition, --with-win-sdk="/path/to/Windows SDK" option is also added to
specify path to Windows SDK, which may be used for native-compile of .tlb
file of qemu-ga VSS provider. However, this is usually unnecessary because
pre-compiled .tlb file is included.

 - Otherwise, c++ is used.

Currently, usage of C++ language is only for access to Windows VSS
using COM+ services in qemu-guest-agent for Windows.

Stefan Weil 1d984a67a9 configure: Don't write .pyc files by default (python -B)
When a Python script is run, Python normally writes bytecode into a .pyc file.
QEMU's build process uses several Python scripts which are called from
configure or make.

The generated .pyc files take disk space without being of much use, because
those scripts are short, not time critical and only called a few times.

Python's option -B disables writing of .pyc files. QEMU now uses "python -B"
as default, but it is still possible to choose a different call by passing
--python=PYTHON to configure.

Peter Maydell 714290979a configure: disable clang -Wstring-plus-int warning
Some versions of clang will warn about adding integers to strings:

disas/i386.c:4753:23: error: adding 'char' to a string does not append
      to the string [-Werror,-Wstring-plus-int]
      oappend ("%es:" + intel_syntax);
               ~~~~~~~^~~~~~~~~~~~~~
disas/i386.c:4753:23: note: use array indexing to silence this warning

                      ^
               &      [             ]

disas/i386.c uses this idiom to to skip a "%" prefix if using intel
rather than AT&T syntax. This seems like a reasonable  thing to do,
and I don't think anybody contributing to QEMU is likely to believe
that '+' is a string concatenation operator in C, so just disable
-Wstring-plus-int.

Peter Maydell 24cb36a61c configure: Make NPTL non-optional
Now all linux-user targets support building with NPTL, we can make it
mandatory. This is a good idea because:
 * NPTL is no longer new and experimental; it is completely standard
 * in practice, linux-user without NPTL is nearly useless for
   binaries built against non-ancient glibc
 * it allows us to delete the rather untested code for handling
   the non-NPTL configuration

Note that this patch leaves the CONFIG_USE_NPTL ifdefs in the
bsd-user codebase alone. This makes no change for bsd-user, since
our configure test for NPTL had a "#include <linux/futex.h>"
which means bsd-user would never have been compiled with
CONFIG_USE_NPTL defined, and it still is not.

Peter Maydell 1ccd9374af linux-user: Enable NPTL for m68k
For m68k, per-thread data is a purely kernel construct with no
CPU level support. Implement it via a field in the TaskState structure,
used by cpu_set_tls() and the set_thread_area/get_thread_area
syscalls. This allows us to enable compilation with NPTL.

Peter Maydell 442a59c8dd linux-user: Enable NPTL for OpenRISC
The OpenRISC kernel ignores CLONE_SETTLS in its copy_thread()
implementation, so a cpu_set_tls() implementation is a no-op.
cpu_clone_regs() was setting the syscall return value in the
wrong register -- it is gpr[11], not gpr[2]. With these two
things fixed, we can compile with NPTL enabled.

For architectures with no linux-user target, don't claim no NPTL
support. This has no behavioural change, but it means that we
won't accidentally add a new linux-user target without threading
support in future (because attempting to do so would be a compile
failure rather than a silent lack of support).
