Stefan Weil 08f3896a07 w32: Use additional library libiberty.a
libiberty.a is part of MinGW and provides useful functions
like ffs (MinGW) and getopt (MinGW-w64).

It is needed for w64 compilations and allows simpler code for w32.

Aurelien Jarno 71deff2749 target-i386: set target_phys_bits to 64
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.

Laurent Vivier c2e3dee6e0 linux-user: Define target alignment size
Datatype alignment can be found using following application:

int main(void)

	printf("alignof(long) %ld\n", __alignof__(long));
	printf("alignof(long long) %ld\n", __alignof__(long long));
}

This patch includes following alignments:

   alignof(long) 4
   alignof(long long) 8

 x86_64

Support the epoll family of syscalls: epoll_create(), epoll_create1(),

Jan Kiszka de758970b6 kvm: Fix race between timer signals and vcpu entry under !IOTHREAD
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.

As all machines except i386 and x86_64 are using softfloat, make it the
default and change the case to detect i386 and x86_64. Note that CRIS
doesn't have an FPU, so it can be configured with both softfloat-native

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);
  }

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.

Stefan Weil 10d554c65a configure: Remove unneeded defines from checks
_GNU_SOURCE is already defined in QEMU_CFLAGS which
is passed to gcc in shell function compile_prog.

Removing the definition from several checks avoids compiler warnings
(which are now written to config.log).

Scott Wood 832ce9c286 configure: include stddef.h for NULL
This fixes an observed failure to detect madvise() on Linux.

To avoid similar issues, all other tests that use NULL but don't already
have stddef.h (or another header that is defined to provide NULL,
such as stdio.h, unistd.h, or time.h) are also fixed.
