      usb-hid: split hid code to hw/hid.[ch] · dcfda673
      由 Gerd Hoffmann 提交于 
      Almost pure code motion.  Unstatic hid interface functions and add
them to the header file.  Some renames.  Some code style cleanups.

      usb: use iovecs in USBPacket · 4f4321c1
      由 Gerd Hoffmann 提交于 
      Zap data pointer from USBPacket, add a QEMUIOVector instead.
Add a bunch of helper functions to manage USBPacket data.
Switch over users to the new interface.

Note that USBPacket->len was used for two purposes:  First to
pass in the buffer size and second to return the number of
transfered bytes or the status code on async transfers.  There
is a new result variable for the latter.  A new status code
was added to catch uninitialized result.

Nobody creates iovecs with more than one element (yet).
Some users are (temporarely) limited to iovecs with a single
element to keep the patch size as small as possible.

      coroutine: implement coroutines using gthread · d0e2fce5
      由 Aneesh Kumar K.V 提交于 
      On platforms that don't support makecontext(3) use gthread based
coroutine implementation.

Darwin has makecontext(3) but getcontext(3) is stubbed out to return
ENOTSUP.  Andreas Färber <andreas.faerber@web.de> debugged this and
contributed the ./configure test which solves the issue for Darwin/ppc64
(and ppc) v10.5.

[Original patch by Aneesh, made consistent with coroutine-ucontext.c and
switched to GStaticPrivate by Stefan.  Tested on Linux and OpenBSD.]

      coroutine: introduce coroutines · 00dccaf1
      由 Kevin Wolf 提交于 
      Asynchronous code is becoming very complex.  At the same time
synchronous code is growing because it is convenient to write.
Sometimes duplicate code paths are even added, one synchronous and the
other asynchronous.  This patch introduces coroutines which allow code
that looks synchronous but is asynchronous under the covers.

A coroutine has its own stack and is therefore able to preserve state
across blocking operations, which traditionally require callback
functions and manual marshalling of parameters.

Creating and starting a coroutine is easy:

  coroutine = qemu_coroutine_create(my_coroutine);
  qemu_coroutine_enter(coroutine, my_data);

The coroutine then executes until it returns or yields:

  void coroutine_fn my_coroutine(void *opaque) {
      MyData *my_data = opaque;

      /* do some work */

      qemu_coroutine_yield();

      /* do some more work */
  }

Yielding switches control back to the caller of qemu_coroutine_enter().
This is typically used to switch back to the main thread's event loop
after issuing an asynchronous I/O request.  The request callback will
then invoke qemu_coroutine_enter() once more to switch back to the
coroutine.

Note that if coroutines are used only from threads which hold the global
mutex they will never execute concurrently.  This makes programming with
coroutines easier than with threads.  Race conditions cannot occur since
only one coroutine may be active at any time.  Other coroutines can only
run across yield.

This coroutines implementation is based on the gtk-vnc implementation
written by Anthony Liguori <anthony@codemonkey.ws> but it has been
significantly rewritten by Kevin Wolf <kwolf@redhat.com> to use
setjmp()/longjmp() instead of the more expensive swapcontext() and by
Paolo Bonzini <pbonzini@redhat.com> for Windows Fibers support.

      libcacard: add libcacard.la target · 44dc0ca3
      由 Alon Levy 提交于 
      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.

      cocoa: Revert dependency on VNC · e949467b
      由 Andreas Färber 提交于 
      In 821601ea (Make VNC support optional)
cocoa.o was moved from ui-obj-$(CONFIG_COCOA) to vnc-obj-$(CONFIG_COCOA),
adding a dependency on $(CONFIG_VNC). That must've been unintentional.
