Gerd Hoffmann 37fb59d303 usb: data structs and helpers for usb descriptors.
This patch adds hw/usb-desc.[ch] files.  They carry data structures
for various usb descriptors and helper functions to generate usb
packets from the structures.

The intention is to have a internal representation of the device
desription which is more usable than the current char array blobs,
so we can have common code handle common usb device emulation using
the device description.

The usage of this infrastructure is optional for usb drivers as there
are cases such as pass-through where it probably isn't very useful.

Stefan Hajnoczi eabba580e6 qed: Read/write support
This patch implements the read/write state machine.  Operations are
fully asynchronous and multiple operations may be active at any time.

Allocating writes lock tables to ensure metadata updates do not
interfere with each other.  If two allocating writes need to update the
same L2 table they will run sequentially.  If two allocating writes need
to update different L2 tables they will run in parallel.

Stefan Hajnoczi 298800cae7 qed: Table, L2 cache, and cluster functions
This patch adds code to look up data cluster offsets in the image via
the L1/L2 tables.  The L2 tables are writethrough cached in memory for
performance (each read/write requires a lookup so it is essential to
cache the tables).

With cluster lookup code in place it is possible to implement
bdrv_is_allocated() to query the number of contiguous
allocated/unallocated clusters.

Christian Brunner f27aaf4b53 ceph/rbd block driver for qemu-kvm
RBD is an block driver for the distributed file system Ceph
(http://ceph.newdream.net/). This driver uses librados (which is part
of the Ceph server) for direct access to the Ceph object store and is
running entirely in userspace (Yehuda also wrote a driver for the
linux kernel, that can be used to access rbd volumes as a block
device).

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

Add support for the spice audio interface.  With this patch applied
audio can be forwarded over the network from/to the spice client.  Both
recording and playback is supported.

The driver is first in the driver list, but the can_be_default flag is
set only in case spice is active.  So if you have the spice protocol
enabled the spice audio driver is the default one, otherwise whatever
comes first after spice in the list.  Overriding the default using
QEMU_AUDIO_DRV works in any case.

Gerd Hoffmann d61a4ce8f0 Add Intel HD Audio support to qemu.
This patch adds three devices to qemu:

intel-hda
	Intel HD Audio Controller, the PCI device.  Provides a HDA bus.
	Emulates ICH6 at the moment.  Adding a ICH9 PCIE
	variant shouldn't be hard.

hda-duplex
	HDA Codec.  Attaches to the HDA bus.  Supports 16bit stereo,
	rates 16k -> 96k, playback, recording and volume control
	(with CONFIG_MIXEMU=y).

hda-output
	HDA Codec without recording support.  Subset of the hda-duplex
	codec.  Use this if you don't want your guests access your mic.

Usage: add '-device intel-hda -device hda-duplex' to your command line.

Tested guests:
 * Linux works.
 * Win7 works.
 * DOS (mpxplay) works.
 * WinXP doesn't work.

[ v2 changes ]
 * Fixed endianess, big endian hosts work now.
 * Fixed some emulation bugs.
 * Added immediate command emulation.
 * Added vmstate support.
 * Make it behave like all other sound card drivers:
   - can be configured via '--audio-card-list=hda'
   - can be added to a VM using '-soundhw hda'
 * Code style fixups.
 * Zapped guest-triggerable asserts.
 * Handle partial reads/writes of audio data correctly.

Michael S. Tsirkin df2943ba3c qemu-options.def: add to generated header list
All files include qemu-options.h which pulls in qemu-options.def from
the root directory.  Thus generating qemu-options.def from Makefile.objs
under the target directory is not effective.

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 fixes the error: ‘QEMU_OPTION_spice’ undeclared
(first use in this function) error that some people reported
which is really down to an out of date .def file.

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.

If you don't want it, just use ./configure --disable-vnc-thread and a syncrhonous

If you disable the VNC thread, all thread related code will not be built and there will
