      w32: Fix configure test for -march=i486 · 1405b629
      由 Stefan Weil 提交于 
      The latest version of MinGW needs a test for __sync_val_compare_and_swap
to fix a missing symbol linker error.

      configure: Detect uuid on MacOSX (fixes compile failure) · 2d16c8e9
      由 Peter Maydell 提交于 
      Commit 7791dba3 broke compilation on MacOSX, because it introduced
a new include of util.h. On MacOSX this includes pwd.h which in turn
includes the system uuid/uuid.h, which causes a compile failure if
QEMU was configured without CONFIG_UUID due to a conflict between
the system header and our fallback versions:
  block/vdi.c:124:20: error: static declaration of 'uuid_generate'
  follows non-static declaration
  static inline void uuid_generate(uuid_t out)
                     ^
  /usr/include/uuid/uuid.h:63:6: note: previous declaration is here
  void uuid_generate(uuid_t out);
       ^

Fix this breakage by improving configure's check for uuid to work on
MacOSX (where there is no need to link in a separate libuuid).

Note that if the user explicitly runs configure with '--disable-uuid'
on MacOSX then QEMU will fail to compile.

      trace: Add ftrace tracing backend · 781e9545
      由 Eiichi Tsukata 提交于 
      This patch adds a ftrace tracing backend which sends trace event to
ftrace marker file. You can effectively compare qemu trace data and
kernel(especially, kvm.ko when using KVM) trace data.
The ftrace backend is restricted to Linux only.

To try out the ftrace backend:

 $ ./configure --trace-backend=ftrace
 $ make

if you use KVM, enable kvm events in ftrace:

 # sudo echo 1 > /sys/kernel/debug/tracing/events/kvm/enable

After running qemu by root user, you can get the trace:

 # cat /sys/kernel/debug/tracing/trace

      block/ssh: Require libssh2 >= 1.2.8. · 4fc16838
      由 Richard W.M. Jones 提交于 
      libssh2 >= 1.2.8 is required to enable this block device (because
that version introduced the libssh2_session_handshake call).

Change the test to use pkg-config exclusively.  If the user requests
--enable-libssh2 and the minimum version is not available, then the
following error is displayed:

  $ ./configure --enable-libssh2

  ERROR: libssh2 >= 1.2.8 required for --enable-libssh2

If --enable-libssh2 is not specified, then the feature is silently
disabled if sufficiently new libssh2 is not available.

      vhost-scsi: new device supporting the tcm_vhost Linux kernel module · 5e9be92d
      由 Nicholas Bellinger 提交于 
      The WWPN specified in configfs is passed to "-device vhost-scsi-pci".
The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not
available from the QEMU command-line.  Instead, I hardcode it to zero.

Changes in Patch-v2:
   - Add vhost_scsi_get_features() in order to determine feature bits
     supports by host kernel (mst + nab)
   - Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow
     EVENT_IDX to be disabled by host in vhost_scsi_get_features()
   - Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES

Changes in Patch-v1:
   - Set event_idx=off by default (nab, thanks asias)
   - Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to
     re-enable in v3.10 (nab)
   - Update to latest qemu.git/master HEAD

Changes in WIP-V3:
   - Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha)
   - Add CONFIG_VHOST_SCSI (asias, thanks stefanha)
   - Add hotplug feature bit

Changes in WIP-V2:
   - Add backend guest masking support (nab)
   - Bump ABI_VERSION to 1 (nab)
   - Set up set_guest_notifiers (asias)
   - Set up vs->dev.vq_index (asias)
   - Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias)
   - Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias)

Howto:
   Use the latest seabios, at least commit b44a7be17b
   git clone git://git.seabios.org/seabios.git
   make
   cp out/bios.bin /usr/share/qemu/bios.bin
   qemu -device vhost-scsi-pci,wwpn=naa.6001405bd4e8476d,event_idx=off

      use libusb for usb-host · 2b2325ff
      由 Gerd Hoffmann 提交于 
      Reimplement usb-host on top of libusb.
Reasons to do this:

 (1) Largely rewritten from scratch, nice opportunity to kill historical
     cruft.
 (2) Offload usbfs handling to libusb.
 (3) Have a single portable code base instead of bsd + linux variants.
 (4) Bring usb-host support to any platform supported by libusbx.

For now this goes side-by-side to the existing code.  That is only to
simplify regression testing though, at the end of the day I want remove
the old code and support libusb exclusively.  Merge early in 1.5 cycle,
remove the old code after 1.5 release or something like this.

Thanks to qdev the old and new code can coexist nicely on linux.  Just
use "-device usb-host-linux" to use the old linux driver instead of the
libusb one (which takes over the "usb-host" name).

The bsd driver isn't qdev'ified so it isn't that easy for bsd.
I didn't bother making it runtime switchable, so you have to rebuild
qemu with --disable-libusb to get back the old code.
