Enabling the I/O thread by default seems like an important part of declaring
1.0. Besides allowing true SMP support with KVM, the I/O thread means that the
TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which
currently requires a (racey) signal based alarm system.
I know there have been concerns about performance. I think so far the ones that
have come up (virtio-net) are most likely due to secondary reasons like
decreased batching.
I think we ought to force enabling I/O thread early in 1.0 development and
commit to resolving any lingering issues.

When using xen_enabled() we're currently only checking if xen is enabled
at all during the build. But what if you want to build multiple targets
out of which only one can potentially run xen code?
That means that for generic code we'll still have to fall back to the
variable and potentially slow the code down, but it's not as important as
that is mostly xen device emulation which is not touched for non-xen targets.
The target specific code however can with this patch see that it's unable to
ever execute xen code. We can thus always return 0 on xen_enabled(), giving
gcc enough hints to evict the mapcache code from the target memory management

This patch adds support for a usb-redir device, which takes a chardev
as a communication channel to an actual usbdevice using the usbredir protocol.
Compiling the usb-redir device requires usbredir-0.3 to be installed for
the usbredir protocol parser, usbredir-0.3 also contains a server for
redirecting usb traffic from an actual usb device. You can get the 0.3
release of usbredir here:
http://people.fedoraproject.org/~jwrdegoede/usbredir-0.3.tar.bz2
(getting a more formal site for it is a WIP)
Example usage:
1) Start usbredirserver for a usb device:
sudo usbredirserver 045e:0772
2) Start qemu with usb2 support + a chardev talking to usbredirserver +
a usb-redir device using this chardev:
qemu ... \
-readconfig docs/ich9-ehci-uhci.cfg \
-chardev socket,id=usbredirchardev,host=localhost,port=4000 \

BeOS and Haiku on i386 use long for 32-bit types, including pid_t.
Using %d with pid_t therefore results in a warning.
Unfortunately POSIX:2008 does not define a PRId* string for pid_t.
In some places pid_t was previously casted to long and %ld hardcoded.
The predecessor of this patch added another upcast for the simpletrace
filename but was not applied to date.
Since new uses of pid_t with %d keep creeping in, let's instead define
an OS-dependent format string and use that consistently.

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.
Under Darwin, a symbol exists for the fdatasync() function, so that our
link test succeeds. However _POSIX_SYNCHRONIZED_IO is set to '-1'.
According to POSIX:2008, a value of -1 means the feature is not supported.
A value of 0 means supported at compilation time, and a value greater 0
means supported at both compilation and run time.
Enable fdatasync() only if _POSIX_SYNCHRONIZED_IO is '>0'.

On IA32 host or IA32 PAE host, at present, generally, we can't create

impossible for Qemu to find a large enough and consecutive virtual
address space to map an HVM guest's whole physical address space.
The attached patch fixes this issue using dynamic mapping based on
little blocks of memory.
Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the
lock option, so mapcache will not unmap these ram_ptr.
Blocks that do not belong to the RAM, but usually to a device ROM or to
a framebuffer, are handled in a separate function. So the whole RAMBlock
can be map.

libcacard: fix out of tree builds
A CCID device is a smart card reader. It is a USB device, defined at [1].
This patch introduces the usb-ccid device that is a ccid bus. Next patches will
introduce two card types to use it, a passthru card and an emulated card.

Comment for "return consistent self-powered state":
the Configuration Descriptor bmAttributes claims we are self powered,
but we were returning not self powered to USB_REQ_GET_STATUS control message.
In practice, this message is not sent by a linux 2.6.35.10-74.fc14.x86_64
guest (not tested on other guests), unless you issue lsusb -v as root (for
example).
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.

rbd support tries to both link with -lrados and -lcrypto. While the
first one is of course necessary, the second is not necessary (only
librados ifself needs to link with libcrypto).
This fixes a licensing issue: qemu as a whole is GPL v2, and thus can't
be linked with OpenSSL without an exception in the license, which seems
difficult to get given the number of persons involved.

qemu i386 used to support more than 4GB of RAM through PAE, but it has
been disabled for an unknown reason. Reenable it.
Note that simply running qemu x86_64 and emulating a 32-bit CPU is not
a solution to this problem as it is about 15% slower (it needs to
emulate 64 bit registers even if half of them are not used). On the
other hand, I haven't seen any measurable impact by switching
target_phys_bits to 64.

Found by Stefan Hajnoczi: There is a race in kvm_cpu_exec between
checking for exit_request on vcpu entry and timer signals arriving
before KVM starts to catch them. Plug it by blocking both timer related
signals also on !CONFIG_IOTHREAD and process those via signalfd.
As this fix depends on real signalfd support (otherwise the timer
signals only kick the compat helper thread, and the main thread hangs),
we need to detect the invalid constellation and abort configure.

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);
}

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.

vl.c has a Sun-specific hack to supply a prototype for madvise(),
but the call site has apparently moved to arch_init.c.
Haiku doesn't implement madvise() in favor of posix_madvise().
OpenBSD and Solaris 10 don't implement posix_madvise() but madvise().
MinGW implements neither.
Check for madvise() and posix_madvise() in configure and supply qemu_madvise()
as wrapper. Prefer madvise() over posix_madvise() due to flag availability.
Convert all callers to use qemu_madvise() and QEMU_MADV_*.
Note that on Solaris the warning is fixed by moving the madvise() prototype,
not by qemu_madvise() itself. It helps with porting though, and it simplifies
most call sites.
v7 -> v8:
* Some versions of MinGW have no sys/mman.h header. Reported by Blue Swirl.
v6 -> v7:
* Adopt madvise() rather than posix_madvise() semantics for returning errors.
* Use EINVAL in place of ENOTSUP.
v5 -> v6:
* Replace two leftover instances of POSIX_MADV_NORMAL with QEMU_MADV_INVALID.
Spotted by Blue Swirl.
v4 -> v5:
* Introduce QEMU_MADV_INVALID, suggested by Alexander Graf.
Note that this relies on -1 not being a valid advice value.
v3 -> v4:
* Eliminate #ifdefs at qemu_advise() call sites. Requested by Blue Swirl.
This will currently break the check in kvm-all.c by calling madvise() with
a supported flag, which will not fail. Ideas/patches welcome.
v2 -> v3:
* Reuse the *_MADV_* defines for QEMU_MADV_*. Suggested by Alexander Graf.
* Add configure check for madvise(), too.
Add defines to Makefile, not QEMU_CFLAGS.
Convert all callers, untested. Suggested by Blue Swirl.
* Keep Solaris' madvise() prototype around. Pointed out by Alexander Graf.
