0bdb12c7c5 rules.mak: quiet-command: Split command name and args to print
The quiet-command make rule currently takes two arguments:
the command and arguments to run, and a string to print if
the V flag is not set (ie we are not being verbose).
By convention, the string printed is of the form
"  NAME   some args". Unfortunately to get nicely lined up
output all the strings have to agree about what column the
arguments should start in, which means that if we add a
new quiet-command usage which wants a slightly longer CMD
name then we either put up with misalignment or change
every quiet-command string.

Split the quiet-mode string into two, the "NAME" and
the "same args" part, and use printf(1) to format the
string automatically. This means we only need to change
one place if we want to support a longer maximum name.

In particular, we can now print 7-character names lined
up properly (they are needed for the OSX "SETTOOL" invocation).

Change all the uses of quiet-command to the new syntax.
(Any which are missed or inadvertently reintroduced
via later merges will result in slightly misformatted
quiet output rather than disaster.)

A few places in the pc-bios/ makefiles are updated to use
"BUILD", "SIGN" and "STRIP" rather than "Building",
"Signing" and "Stripping" for consistency and to keep them
below 7 characters. Module .mo links now print "LD" rather
than the nonstandard "LD -r".

dced7eec3c s390x/cpumodel: generate CPU feature lists for CPU models
This patch introduces the helper "gen-features" which allows to generate
feature list definitions at compile time. Its flexibility is better and the
error-proneness is lower when compared to static programming time added
statements.

The helper includes "target-s390x/cpu_features.h" to be able to use named
facility bits instead of numbers. The generated defines will be used for
the definition of CPU models.

We generate feature lists for each HW generation and GA for EC models. BC
models are always based on a EC version and have no separate definitions.

Base features: Features we expect to be always available in sane setups.
Migration safe - will never change. Can be seen as "minimum features
required for a CPU model".

Default features: Features we expect to be stable and around in latest
setups (e.g. having KVM support) - not migration safe.

Max features: All supported features that are theoretically allowed for a
CPU model. Exceeding these features could otherwise produce problems with
IBC (instruction blocking controls) in KVM.

ba4537805d linux-user: Create a hostdep.h for each host architecture
In commit 4d330cee37 a new hostdep.h file was added, with the intent
that host architectures which needed one could provide it, and the
build system would automatically fall back to a generic version if
there was no version for the host architecture. Although this works,
it has a flaw: if a subsequent commit switches an architecture from
"uses generic/hostdep.h" to "uses its own hostdep.h" nothing in the
makefile dependencies notices this and so doing a rebuild without
a manual 'make clean' will fail.

So we drop the idea of having a 'generic' version in favour of
every architecture we support having its own hostdep.h, even if
it doesn't have anything in it. (There are only thirteen of these.)

If the dependency files claim that an object file depends on a
nonexistent file, our dependency system means that make will
rebuild the object file, and regenerate the dependencies in
the process. So moving between trees prior to this commit and
trees after this commit works without requiring a 'make clean'.

4d330cee37 linux-user: Provide safe_syscall for fixing races between signals and syscalls
If a signal is delivered immediately before a blocking system call the
handler will only be called after the system call returns, which may be a
long time later or never.

This is fixed by using a function (safe_syscall) that checks if a guest
signal is pending prior to making a system call, and if so does not call the
system call and returns -TARGET_ERESTARTSYS. If a signal is received between
the check and the system call host_signal_handler() rewinds execution to
before the check. This rewinding has the effect of closing the race window
so that safe_syscall will reliably either (a) go into the host syscall
with no unprocessed guest signals pending or or (b) return
-TARGET_ERESTARTSYS so that the caller can deal with the signals.
Implementing this requires a per-host-architecture assembly language
fragment.

This will also resolve the mishandling of the SA_RESTART flag where
we would restart a host system call and not call the guest signal handler
until the syscall finally completed -- syscall restarting now always
happens at the guest syscall level so the guest signal handler will run.
(The host syscall will never be restarted because if the host kernel
rewinds the PC to point at the syscall insn for a restart then our
host_signal_handler() will see this and arrange the guest PC rewind.)

This commit contains the infrastructure for implementing safe_syscall
and the assembly language fragment for x86-64, but does not change any
syscalls to use it.

666a3af9c8 io: add abstract QIOChannel classes
Start the new generic I/O channel framework by defining a
QIOChannel abstract base class. This is designed to feel
similar to GLib's GIOChannel, but with the addition of
support for using iovecs, qemu error reporting, file
descriptor passing, coroutine integration and use of
the QOM framework for easier sub-classing.

The intention is that anywhere in QEMU that almost
anywhere that deals with sockets will use this new I/O
infrastructure, so that it becomes trivial to then layer
in support for TLS encryption. This will at least include
the VNC server, char device backend and migration code.

fb37726db7 crypto: move crypto objects out of libqemuutil.la
Future patches will be adding more crypto related APIs which
rely on QOM infrastructure. This creates a problem, because
QOM relies on library constructors to register objects. When
you have a file in a static .a library though which is only
referenced by a constructor the linker is dumb and will drop
that file when linking to the final executable :-( The only
workaround for this is to link the .a library to the executable
using the -Wl,--whole-archive flag, but this creates its own
set of problems because QEMU is relying on lazy linking for
libqemuutil.a. Using --whole-archive majorly increases the
size of final executables as they now contain a bunch of
object code they don't actually use.

The least bad option is to thus not include the crypto objects
in libqemuutil.la, and instead define a crypto-obj-y variable
that is referenced directly by all the executables that need
this code (tools + softmmu, but not qemu-ga). We avoid pulling
entire of crypto-obj-y into the userspace emulators as that
would force them to link to gnutls too, which is not required.

12a1ddc160 Makefile.target: include top level build dir in vpath
Using ccache with CCACHE_BASEDIR set to $(SRC_PATH) or a parent will
rewrite all absolute paths to relative paths. This interacts poorly with
QEMU's two-level build directory scheme. For example, lets say
BUILD_DIR=$(SRC_PATH)/build so build/blockdev.d will contain:

  blockdev.o: ../blockdev.c ../include/sysemu/block-backend.h \

Now the target build under build/x86_64-softmmu or similar will depend
on ../blockdev.o which in turn will get make to source ../blockdev.d to
check its dependencies. Since make always considers paths relative to
the current working directory rather than the makefile the path appeared
in the relative path to ../blockdev.c is useless.

This change simply adds the top level build directory to vpath so paths
relative to the source directory, top build directory, and target build
directory all work just fine.

6b4ad3b28d Makefile.target: set master BUILD_DIR
make can be invoked in the individual build dirs to build an individual
target or just a single file of a target. e.g.

touch translate-all.c
make -C microblazeel-softmmu translate-all.o

There is however a small bug when using the pixman submodule.
config-host.mak will ref BUILD_DIR for the pixman -I CFLAGS:

grep BUILD_DIR config-host.mak
QEMU_CFLAGS=-I$(SRC_PATH)/pixman/pixman -I$(BUILD_DIR)/pixman/pixman ...

This causes a build failure as -I/pixman/pixman (BUILD_DIR=="") will
not be found.

BUILD_DIR is usually set by the top level Makefile. Just lazy-set it in
Makefile.target to the parent directory.

Granted, this will not work if the pixman submodule is not prebuilt,
but it at least means you can do incremental partial builds once you
have done your initial full build (or attempt) from the top level.

The next step would be refactor make infrastructure to rebuild pixman
on a submake like the one above.

7398dfc779 Makefile.target: prepend $libs_softmmu to $LIBS
I discovered a problem when trying to build QEMU statically with gcc.
libm is an element of LIBS while libpixman-1 is an element in
libs_softmmu. Libpixman references functions in libm, so the original
ordering makes linking fail.

This fix is to reorder $libs_softmmu and $LIBS to make -lm appear after
-lpixman-1. However I'm not quite sure if this is the right fix, hence
the RFC tag.

Normally QEMU is built with c++ compiler which happens to link in libm
(at least this is the case with g++), so building QEMU statically
normally just works and nobody notices this issue.

e0b2fd0efb trace: install simpletrace SystemTap tapset
The simpletrace SystemTap tapset outputs simpletrace binary traces for
SystemTap probes.  This is useful because SystemTap has no default way
to format or store traces.  The simpletrace SystemTap tapset provides an
easy way to store traces.

The simpletrace.py tool or custom Python scripts using the
simpletrace.py API can analyze SystemTap these traces:

  $ ./configure --enable-trace-backends=dtrace ...
  $ make && make install
  $ stap -e 'probe qemu.system.x86_64.simpletrace.* {}' \
         -c qemu-system-x86_64 >/tmp/trace.out
  $ scripts/simpletrace.py --no-header trace-events /tmp/trace.out
  g_malloc 4.531 pid=15519 size=0xb ptr=0x7f8639c10470
  g_malloc 3.264 pid=15519 size=0x300 ptr=0x7f8639c10490
  g_free 5.155 pid=15519 ptr=0x7f8639c0f7b0

Note that, unlike qemu-system-x86_64.stp and
qemu-system-x86_64.stp-installed, only one file is needed since the
simpletrace SystemTap tapset does not reference the QEMU binary by path.
Therefore it doesn't matter whether the QEMU binary is installed or not.

f80ea9862f configure: Fix -lm test, so that tools can be compiled on hosts that require -lm
The existing test whether "-lm" needs to be included or not is
insufficient as it reports false negative on Fedora20/ppc64.
This happens because sin(0.0) is a constant value which compiler
can safely throw away and therefore there is no need to add "-lm".
As the result, qemu-nbd/qemu-io/qemu-img tools cannot compile.

5b808275f3 trace: Multi-backend tracing
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.

2115182f0c Makefile: strip tools and modules too
Commit 52ba784d3 replaced $(STRIP_OPT) with $(STRIP) in some
places (for example, Makefile.target), but not all of them.
There are a few places remain in main Makefile which still
uses $(STRIP_OPT).  Replace these places with $(STRIP) too.

While at it, simplify variable pattern substitution of the
surrounding places, change $(patsubst pat,rep,$(var)) into
$(var:pat=rep) which is much easier to read (this is probably
a good idea to do everywhere).

ba1183da9a rules.mak: fix $(obj) to a real relative path

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

The starting point of $(obj) is passed in as argument of unnest-vars, as

3bc2f570ec build: replace weak symbols with a static library
Weak symbols were a nice idea, but they turned out not to be a good one.
Toolchain support is just too sparse, in particular llvm-gcc is totally
broken.

This patch uses a surprisingly low-tech approach: a static library.
Symbols in a static library are always overridden by symbols in an
object file.  Furthermore, if you place each function in a separate
source file, object files for unused functions will not be taken in.
This means that each function can use all the dependencies that it needs
(especially QAPI stuff such as error_setg).

Thus, all stubs are placed in separate object files and put together in
a static library.  The library then is linked to all programs.

c353f26194 build: move per-target hw/ objects to nested Makefile.objs
This completes the move to nested Makefiles for virtio and a few
other files that were not part of obj-TARGET-y, but still were
compiled separately for each target.

99100dc3b5 build: move rules for nesting to Makefile.objs
At this point we will start adding nesting behavior to other files
than Makefile.target.  Because Makefile.objs is included by
Makefile.target, it is simpler to move the processing of
subdirectories there.

To enable this, only add per-target files to obj-y.  Use a separate
variable for the linker dependencies, all-obj-y.  This variable includes
obj-y and also all objects that are taken from other directories.

5f86146fb3 dump: remove dumping stuff from cpu-all.h
This simplifies things, because they will only be included for softmmu
targets and because the stubs are taken out-of-line in separate files,
which in the future could even be compiled only once.

4115852bb0 build: do not sprinkle around GENERATED_HEADERS dependencies
Keeping GENERATED_HEADERS dependencies up-to-date everywhere is complex.
We can simply make the Makefile depend on them, and they will be built
before all other targets.

783e9b4826 introduce a new monitor command 'dump-guest-memory' to dump guest's memory
The command's usage:
   dump-guest-memory [-p] protocol [begin] [length]
The supported protocol can be file or fd:
1. file: the protocol starts with "file:", and the following string is
   the file's path.
2. fd: the protocol starts with "fd:", and the following string is the
   fd's name.

Note:
  1. If you want to use gdb to process the core, please specify -p option.
     The reason why the -p option is not default is:
       a. guest machine in a catastrophic state can have corrupted memory,
          which we cannot trust.
       b. The guest machine can be in read-mode even if paging is enabled.
          For example: the guest machine uses ACPI to sleep, and ACPI sleep
          state goes in real-mode.
  2. If you don't want to dump all guest's memory, please specify the start
     physical address and the length.

0adb124659 Drop darwin-user
It's been orphaned, not compiling for a long time and despite Apple's
drop of their Rosetta ppc emulation technology with Mac OS X Lion no one
has stepped up to fix it.

Testing necessary changes wrt QOM'ification thus is impossible, so we
might as well remove it completely.
