Hi all,
This only came to my attention when building qemu on a colleague's machine recently, but there are
some dependencies for the build that are not detected during the standard `configure` process. In
particular, missing autoconf was not detected until running `make` itself. Also missing li

Hi everybody,
Those are the two first patch-set we have been worked on for reverse execution.

icount: introduce icount timer.

This allows gdb to reverse step QEMU: reverse-stepi and reverse-cont commands

The new directive in the form { 'include': 'path/to/file.json' } will trigger
the
parsing of path/to/file.json.
The directive will be replaced by the result of the parsing.
This will allow for easy modularisation of qapi JSON descriptions files.

SystemTap sdt.h sometimes results in compiled probes without sufficient
information to extract arguments. See code comment for details on this
workaround.
This patch fixes the apic_reset_irq_delivered() trace event on Fedora 20
with gcc-4.8.2-7.fc20 and systemtap-sdt-devel-2.4-2.fc20 on x86_64.

The first patch make an error path in the test more explicit.
The second create an include directive for QAPI JSON files.
The purpose of this series is to be able to add QMP to qemu-nbd in a not so
distant future.

this patch tries to optimize zero write requests
by automatically using bdrv_write_zeroes if it is
supported by the format.
this should significantly speed up file system initialization and
should speed zero write test used to test backend storage performance.
the difference can simply be tested

Oh. address_space_translate() actually changes @len to min(len,

Since qemu/sockets.h exposes the OpenBSD namespace,

Right now qemu does appearently just emulate a graphics card (Cirrus for
example), but not an attached monitor/display. The result is confusion
in the guest OS.
The current DRM drivers in upstream Linux seem to default to VESA modes.
These are either provided by qemu, or Xorg uses a fixed intern

Hi,
I'm thinking about how to handle multihead and multiseat in qemu best.
On multihead: Mouse in virtual machines works best with absolute
coordinates, and the way this is done today is to assign a (virtual) usb
tablet to the guest. With multihead this becomes a bit difficuilt.

The throttling delay calculation was using an inaccurate sector count to
calculate the time to sleep. This broke rate-limiting for the block
mirror job.
Move the delay calculation into mirror_iteration() where we know how
many sectors were transferred. This lets us calculat
The mirror blockjob coroutine rate-limits itself by sleeping. The
coroutine also performs I/O asynchronously so it's important that the
aio callback doesn't wake the coroutine early as that breaks
rate-limiting.

Make code using the same indicators point to a single allocated structure
that is freed when the last user goes away.
This will be used by the irqfd code to unmap addresses after the last user
