Michael Roth e3d4d25206 guest agent: add guest agent RPCs/commands
This adds the initial set of QMP/QAPI commands provided by the guest
agent:

guest-sync
guest-ping
guest-info
guest-shutdown
guest-file-open
guest-file-read
guest-file-write
guest-file-seek
guest-file-flush
guest-file-close
guest-fsfreeze-freeze
guest-fsfreeze-thaw
guest-fsfreeze-status

The input/output specification for these commands are documented in the
schema.

Example usage:

  host:
    qemu -device virtio-serial \
         -chardev socket,path=/tmp/vs0.sock,server,nowait,id=qga0 \
         -device virtserialport,chardev=qga0,name=org.qemu.quest_agent.0
         ...

    echo "{'execute':'guest-info'}" | socat stdio unix-connect:/tmp/qga0.sock

  guest:
    qemu-ga -m virtio-serial -p /dev/virtio-ports/org.qemu.guest_agent.0 \

Michael Roth 48ff7a625b guest agent: qemu-ga daemon
This is the actual guest daemon, it listens for requests over a
virtio-serial/isa-serial/unix socket channel and routes them through
to dispatch routines, and writes the results back to the channel in
a manner similar to QMP.

A shorthand invocation:

  qemu-ga -d

Is equivalent to:

  qemu-ga -m virtio-serial -p /dev/virtio-ports/org.qemu.guest_agent.0 \
          -f /var/run/qemu-ga.pid -d

Anthony Liguori e18df14185 Add hard build dependency on glib
GLib is an extremely common library that has a portable thread implementation
along with tons of other goodies.

GLib and GObject have a fantastic amount of infrastructure we can leverage in
QEMU including an object oriented programming infrastructure.

Short term, it has a very nice thread pool implementation that we could leverage
in something like virtio-9p.  It also has a test harness implementation that
this series will use.

Alon Levy 44dc0ca3d2 libcacard: add libcacard.la target
No flag to configure is required. Instead, added a libcacard.la target that
is not built by default, only when requested explicitly via:

mkdir build
cd build
../configure
make libcacard.la
make install-libcacard

Uses libtool to do actual linking of object files and shared library, and
installing. Tested only under linux, but supposed to work on other systems as
well.

If libtool isn't found you get a message complaining about that, only at build
time (since it is not a default target I did not add a message at configure
time).

New build artifacts:
 .libs subdirectories (at <buildroot> and <buildroot>/libcacard)
 *.lo files (at same locations as the respective o files)

Added %.lo : %.c rule that uses libtool.
Updated clean rule to clean up those artifacts.
Added specific rule to call dtrace with libtool wrapper (note that because of
a current upstream dtrace bug fixed by systemtap b1568fd85 commit the -fPIC flag
isn't actually passed on. still current dtrace+libtool produced object links fine).
If libtool is missing any of the following targets will complain and exit 1:
 any subdir: *.lo
 root and libcacard: libcacard.la, libcacard-instsall

Tested to link and load with all tracing backends.

David Gibson a9f8ad8f2a Add SLOF-based partition firmware for pSeries machine, allowing more boot options
Currently, the emulated pSeries machine requires the use of the
-kernel parameter in order to explicitly load a guest kernel.  This
means booting from the virtual disk, cdrom or network is not possible.

This patch addresses this limitation by inserting a within-partition
firmware image (derived from the "SLOF" free Open Firmware project).
If -kernel is not specified, qemu will now load the SLOF image, which
has access to the qemu boot device list through the device tree, and
can boot from any of the usual virtual devices.

In order to support the new firmware, an extension to the emulated
machine/hypervisor is necessary.  Unlike Linux, which expects
multi-CPU entry to be handled kexec() style, the SLOF firmware expects
only one CPU to be active at entry, and to use a hypervisor RTAS
method to enable the other CPUs one by one.

This patch also implements this 'start-cpu' method, so that SLOF can
start the secondary CPUs and marshal them into the kexec() holding
pattern ready for entry into the guest OS.  Linux should, and in the
future might directly use the start-cpu method to enable initially
disabled CPUs, but for now it does require kexec() entry.

David Gibson 39ac845510 Implement hcall based RTAS for pSeries machines
On pSeries machines, operating systems can instantiate "RTAS" (Run-Time
Abstraction Services), a runtime component of the firmware which implements
a number of low-level, infrequently used operations.  On logical partitions
under a hypervisor, many of the RTAS functions require hypervisor
privilege.  For simplicity, therefore, hypervisor systems typically
implement the in-partition RTAS as just a tiny wrapper around a hypercall
which actually implements the various RTAS functions.

This patch implements such a hypercall based RTAS for our emulated pSeries
machine.  A tiny in-partition "firmware" calls a new hypercall, which
looks up available RTAS services in a table.

Daniel P. Berrange b3d08c029d Add a DTrace tracing backend targetted for SystemTAP compatability
This introduces a new tracing backend that targets the SystemTAP
implementation of DTrace userspace tracing. The core functionality
should be applicable and standard across any DTrace implementation
on Solaris, OS-X, *BSD, but the Makefile rules will likely need
some small additional changes to cope with OS specific build
requirements.

This backend builds a little differently from the other tracing
backends. Specifically there is no 'trace.c' file, because the
'dtrace' command line tool generates a '.o' file directly from
the dtrace probe definition file. The probe definition is usually
named with a '.d' extension but QEMU uses '.d' files for its
external makefile dependancy tracking, so this uses '.dtrace' as
the extension for the probe definition file.

The 'tracetool' program gains the ability to generate a trace.h
file for DTrace, and also to generate the trace.d file containing
the dtrace probe definition.

Example usage of a dtrace probe in systemtap looks like:

  probe process("qemu").mark("qemu_malloc") {
    printf("Malloc %d %p\n", $arg1, $arg2);
  }

* .gitignore: Ignore trace-dtrace.*
* Makefile: Extra rules for generating DTrace files
* Makefile.obj: Don't build trace.o for DTrace, use
  trace-dtrace.o generated by 'dtrace' instead
* tracetool: Support for generating DTrace data files

Further, people expect .def file to get cleaned with make clean:
it does not have state so no reason to defer removing it
until distclean. Also add a rule to remove old files that might
be around.

This file contains a copy of the following information from the

    o QObject handlers entries

Right now it's only used to generate the QMP docs in QMP/, but
next commits will turn this into QMP's command dispatch table.

It's important to note that QObject handlers entries are going
to get duplicated: they will exist in both QMP's and HMP's
dispatch tables.

This will be fixed in the near future, when we add a proper
QMP call interface and HMP is converted to use it. This way we
can completely drop QObject handlers entries from HMP's tables.

NOTE: HMP specific constructions, like "q|quit", have been dropped.

Andreas Färber 91f169004d trace: Fix user emulator dependency on trace objects
On a clean build, after generating trace.h, make would recurse into *-*-user
without a clue how to build ../trace.o (added to $(obj-y) in Makefile.target)
since its generation rule is in the main Makefile.
The softmmus are seemingly unaffected because the $(TOOLS), which each have
a dependency on $(trace-obj-y), are built first for the build-all target.

Add a dependency on $(trace-obj-y) for %-user, as done for the qemu-* tools.

Let's be paranoid and do the same for %-softmmu while at it, just in case
someone messes with $(TOOLS) or calls the Makefile target directly.

Stefan Hajnoczi 26f7227bfe trace: Add simple built-in tracing backend
This patch adds a simple tracer which produces binary trace files.  To
try out the simple backend:

$ ./configure --trace-backend=simple
$ make

After running QEMU you can pretty-print the trace:

$ ./simpletrace.py trace-events trace.log

The output of simpletrace.py looks like this:

  qemu_realloc 0.699 ptr=0x24363f0 size=0x3 newptr=0x24363f0
  qemu_free 0.768 ptr=0x24363f0
  ^           ^---- timestamp delta (us)
  |____ trace event name

trace: Make trace record fields 64-bit

Explicitly use 64-bit fields in trace records so that timestamps and
magic numbers work for 32-bit host builds.

Stefan Hajnoczi 94a420b170 trace: Add trace-events file for declaring trace events
This patch introduces the trace-events file where trace events can be
declared like so:

qemu_malloc(size_t size) "size %zu"
qemu_free(void *ptr) "ptr %p"

These trace event declarations are processed by a new tool called
tracetool to generate code for the trace events.  Trace event
declarations are independent of the backend tracing system (LTTng User
Space Tracing, ftrace markers, DTrace).

The default "nop" backend generates empty trace event functions.
Therefore trace events are disabled by default.

The trace-events file serves two purposes:

1. Adding trace events is easy.  It is not necessary to understand the
   details of a backend tracing system.  The trace-events file is a
   single location where trace events can be declared without code
   duplication.

2. QEMU is not tightly coupled to one particular backend tracing system.
   In order to support tracing across QEMU host platforms and to
   anticipate new backend tracing systems that are currently maturing,
   it is important to be flexible and not tied to one system.

This commit includes fixes from Prerna Saxena
<prerna@linux.vnet.ibm.com> and Blue Swirl <blauwirbel@gmail.com>.
