      trace: install trace-events file · 89ae5831
      由 Stefan Hajnoczi 提交于 
      Install the ./trace-events file into the data directory.  This file
contains the list of trace events that were built into QEMU at
compile-time.

The file is a handy reference for the set of trace events that the QEMU
binary was built with.  It is also needed by the simpletrace.py tool
that parses binary trace data either emitted from QEMU when built with
--enable-trace-backend=simple or by the SystemTap simpletrace script
that QEMU provides.

      trace: Multi-backend tracing · 5b808275
      由 Lluís Vilanova 提交于 
      Adds support to compile QEMU with multiple tracing backends at the same time.

For example, you can compile QEMU with:

  $ ./configure --enable-trace-backends=ftrace,dtrace

Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system.

This patch allows having both available without recompiling QEMU.

      Makefile: remove bashism · 9c269f6d
      由 Michael Tokarev 提交于 
      When installing modules (when --enable-modules is specified for
./configure), Makefile uses the following construct to replace all
slashes with dashes in module name:

 ${s//\//-}

This is a bash-specific substitution mechanism.  POSIX does not
have it, and some operating systems (for example Debian) does not
implement this construct in default shell (for example dash).

Use more traditional way to perform the substitution: use `tr' tool.

      Makefile: Fix "make clean" · f4b11eee
      由 Fam Zheng 提交于 
      This fixes a dangerous bug: "make clean" after "make distclean" will
delete every single file including those under .git, if you do in-tree
build!

Rationale: A first "make distclean" will unset $(DSOSUF), a following
"make distclean" or "make clean" will find all the files and delete it.

Fix it by explicitly typing the file extensions here, and combine
multiple find invocations into one.

      module: implement module loading · e26110cf
      由 Fam Zheng 提交于 
      This patch adds loading, stamp checking and initialization of modules.

The init function of dynamic module is no longer directly called as
__attribute__((constructor)) in static linked version, it is called
only after passed the checking of presense of stamp symbol:

    qemu_stamp_$RELEASEHASH

where $RELEASEHASH is generated by hashing version strings and content
of configure script.

With this, modules built from a different tree/version/configure will
not be loaded.

The module loading code requires gmodule-2.0.

Modules are searched under
 - CONFIG_MODDIR
 - executable folder (to allow running qemu-{img,io} in the build
   directory)
 - ../ of executable folder (to allow running system emulator in the
   build directory)

Modules are linked under their subdir respectively, then copied to top
level of build directory for above convinience, e.g.:
    $(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so

      rules.mak: introduce DSO rules · 17969268
      由 Fam Zheng 提交于 
      Add necessary rules and flags for shared object generation.
The new rules introduced here are:

1) %.o in $(common-obj-m) is compiled to %.o, then linked to %.so.

2) %.mo in $(common-obj-m) is the placeholder for %.so for pattern
matching in Makefile. It's linked to "-shared" with all its dependencies
(multiple *.o) as input. Which means the list of depended objects must
be specified in each sub-Makefile.objs:

    foo.mo-objs := bar.o baz.o qux.o

in the same style with foo.o-cflags and foo.o-libs. The objects here
will be prefixed with "$(obj)/" if it's a subdirectory Makefile.objs.

3) For all files ending up in %.so, the following is added automatically:

    foo.o-cflags += -fPIC -DBUILD_DSO

Also introduce --enable-modules in configure, the option will enable
support of shared object build. Otherwise objects are static linked to
executables.

      rules.mak: fix $(obj) to a real relative path · ba1183da
      由 Fam Zheng 提交于 
      Makefile.target includes rule.mak and unnested common-obj-y, then prefix
them with '../', this will ignore object specific QEMU_CFLAGS in subdir
Makefile.objs:

    $(obj)/curl.o: QEMU_CFLAGS += $(CURL_CFLAGS)

Because $(obj) here is './block', instead of '../block'. This doesn't
hurt compiling because we basically build all .o from top Makefile,
before entering Makefile.target, but it will affact arriving per-object
libs support.

The starting point of $(obj) is passed in as argument of unnest-vars, as
well as nested variables, so that different Makefiles can pass in a
right value.

      sun4m: Add FCode ROM for TCX framebuffer · da87dd7b
      由 Mark Cave-Ayland 提交于 
      Upstream OpenBIOS now implements SBus probing in order to determine the
contents of a physical bus slot, which is required to allow OpenBIOS to
identify the framebuffer without help from the fw_cfg interface.

SBus probing works by detecting the presence of an FCode program
(effectively tokenised Forth) at the base address of each slot, and if
present executes it so that it creates its own device node in the
OpenBIOS device tree.

The FCode ROM is generated as part of the OpenBIOS build and should
generally be updated at the same time.

      qemu-ga: Add Windows VSS provider and requester as DLL · b39297ae
      由 Tomoki Sekiyama 提交于 
      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).

      qemu-ga: Add configure options to specify path to Windows/VSS SDK · d9840e25
      由 Tomoki Sekiyama 提交于 
      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.
