hw/ptimer: Update .delta on period/freq change

Delta value must be updated on period/freq change, otherwise running timer
would be restarted (counter reloaded with old delta). Only m68k/mcf520x
and arm/arm_timer devices are currently doing freq change correctly, i.e.
stopping the timer. Perform delta update to fix affected devices and
eliminate potential further mistakes.

hw/ptimer: Perform counter wrap around if timer already expired

ptimer_get_count() might be called while QEMU timer already been expired.
In that case ptimer would return counter = 0, which might be undesirable
in case of polled timer. Do counter wrap around for periodic timer to keep
it distributed. In order to achieve more accurate emulation behaviour of
certain hardware, don't perform wrap around when in icount mode and return
counter = 0 in that case (that doesn't affect polled counter distribution).

hw/ptimer: Fix issues caused by the adjusted timer limit value

Multiple issues here related to the timer with a adjusted .limit value:

1) ptimer_get_count() returns incorrect counter value for the disabled
timer after loading the counter with a small value, because adjusted limit
value is used instead of the original.

For instance:
    1) ptimer_stop(t)
    2) ptimer_set_period(t, 1)
    3) ptimer_set_limit(t, 0, 1)
    4) ptimer_get_count(t) <-- would return 10000 instead of 0

2) ptimer_get_count() might return incorrect value for the timer running
with a adjusted limit value.

For instance:
    1) ptimer_stop(t)
    2) ptimer_set_period(t, 1)
    3) ptimer_set_limit(t, 10, 1)
    4) ptimer_run(t)
    5) ptimer_get_count(t) <-- might return value > 10

3) Neither ptimer_set_period() nor ptimer_set_freq() are adjusting the
limit value, so it is still possible to make timer timeout value
arbitrary small.

For instance:
    1) ptimer_set_period(t, 10000)
    2) ptimer_set_limit(t, 1, 0)
    3) ptimer_set_period(t, 1) <-- bypass limit correction

Fix all of the above issues by adjusting timer period instead of the limit.
Perform the adjustment for periodic timer only. Use the delta value instead
of the limit to make decision whether adjustment is required, as limit could
be altered while timer is running, resulting in incorrect value returned by
ptimer_get_count.

 * IL doesn't indicate Thumb-vs-ARM, it indicates instruction
   length (which may be 16 or 32 for Thumb and is always 32 for ARM)
 * not every syndrome format uses IL like this -- for some IL is
   always set, and for some it is always clear
 * the code is changing esr_el[new_el] even for interrupt entry,
   which is not supposed to modify ESR_ELx at all

Delete the code, and instead rely on the syndrome value in

correct value of IL.

vmsvga: don't process more than 1024 fifo commands at once

vmsvga_fifo_run is called in regular intervals (on each display update)
and will resume where it left off.  So we can simply exit the loop,
without having to worry about how processing will continue.

vmsvga: shadow fifo registers

The fifo is normal ram.  So kvm vcpu threads and qemu iothread can
access the fifo in parallel without syncronization.  Which in turn
implies we can't use the fifo pointers in-place because the guest
can try changing them underneath us.  So add shadows for them, to
make sure the guest can't modify them after we've applied sanity
checks.

e1000e: Fix build with ust trace backend

ust trace backend has limitation of maximum 10
arguments per event. Traces with more arguments
cannot be compiled for this backend.

Trace e1000e_rx_rss_ip6 introduced by previous
commits has 11 arguments and fails to compile with
ust trace backend.

This patch fixes the problem by splitting this
tracepoint into two successive tracepoints with
smaller number of arguments.

For more information see comment regarding TP_ARGS
in lttng/tracepoint.h:

/*
* TP_ARGS takes tuples of type, argument separated by a comma.
* It can take up to 10 tuples (which means that less than 10 tuples is
* fine too).
* Each tuple is also separated by a comma.

audio: pa: Set volume of recording stream instead of recording device

Since pulseaudio 1.0 it's possible to set the individual stream volume
rather than setting the device volume. With this, setting hardware mixer
of a emulated sound card doesn't mess up the volume configuration of the

A side effect is that this limits compatible pulseaudio version to 1.0

So, we need another way to handle the underlying issue.  Lets create a

underlying storage, hook up a destroy callback which releases the

vnc: Add support for color map

Our current VNC code does not handle color maps (aka non-true-color) at all
and aborts if a client requests them. There are 2 major issues with this:

 1) A VNC viewer on an 8-bit X11 system may request color maps
 2) RealVNC _always_ starts requesting color maps, then moves on to full color

In order to support these 2 use cases, let's just create a fake color map
that covers exactly our normal true color 8 bit color space. That way we don't
lose anything over a client that wants true color.

When writing the MMFR register, bit 29 and 28 select the requested operation.
 * 10 means read operation with valid MII mgmt frame
 * 11 means read operation with non compliant MII mgmt frame
 * 01 means write operation with valid MII mgmt frame
 * 00 means write operation with non compliant MII mgmt frame

So while bit 28 does change beween read/write for valid MII mgmt frame, the
mening is inverted for non compliant MII mgmt frame.

Bit 29 on the other hand means read/write whatever the type of mgmt frame
involved.

So this patch change the operation selection from bit 28 to bit 29 as it is

net: Introduce e1000e device emulation

This patch introduces emulation for the Intel 82574 adapter, AKA e1000e.

This implementation is derived from the e1000 emulation code, and
utilizes the TX/RX packet abstractions that were initially developed for
the vmxnet3 device. Although some parts of the introduced code may be
shared with e1000, the differences are substantial enough so that the
only shared resources for the two devices are the definitions in
hw/net/e1000_regs.h.

Similarly to vmxnet3, the new device uses virtio headers for task
offloads (for backends that support virtio extensions). Usage of
virtio headers may be forcibly disabled via a boolean device property
"vnet" (which is enabled by default). In such case task offloads
will be performed in software, in the same way it is done on
backends that do not support virtio headers.

The device code is split into two parts:

  1. hw/net/e1000e.c: QEMU-specific code for a network device;
  2. hw/net/e1000e_core.[hc]: Device emulation according to the spec.

The new device name is e1000e.

Intel specifications for the 82574 controller are available at:
http://www.intel.com/content/dam/doc/datasheet/82574l-gbe-controller-datasheet.pdf

docker: Add test runner

It's better to have a launcher for all tests, to make it easier to
initialize and manage the environment.

If "DEBUG=1"  a shell prompt will show up before the test runs.

Makefile: Rules for docker testing

This adds a group of make targets to run docker tests, all are available
in source tree without running ./configure.

The usage is shown with "make docker".

Besides the fixed ones, dynamic targets for building each image and
running each test in each image are generated automatically by make,
scanning $(SRC_PATH)/tests/docker/ files with specific patterns.

Alternative to manually list particular targets (docker-TEST@IMAGE)
set, you can control which tests/images to run by filtering variables,
TESTS= and IMAGES=, which are expressed in Makefile pattern syntax,
"foo% %bar ...". For example:

    $ make docker-test IMAGES="ubuntu fedora"

Unfortunately, it's impossible to propagate "-j $JOBS" into make in
containers, however since each combination is made a first class target
in the top Makefile, "make -j$N docker-test" still parallels the tests
coarsely.

Still, $J is made a magic variable to let all make invocations in
containers to use -j$J.

Instead of providing a live version of the source tree to the docker
container we snapshot it with git-archive. This ensures the tree is in a
pristine state for whatever operations the container is going to run on
them.

Uncommitted changes known to files known by the git index will be
included in the snapshot if there are any.

Makefile: Always include rules.mak

When config-host.mak is not found it is safe to assume SRC_PATH is ".".
So, it is okay to move inclusion of ruls.mak out of the ifeq condition.

rules.mak: Add "COMMA" constant

tests: Add utilities for docker testing

docker.py is added with a number of useful subcommands to manager docker
images and instances for QEMU docker testing. Subcommands are:

run: A wrapper of "docker run" (or "sudo -n docker run" if necessary),
which takes care of killing and removing the running container at
SIGINT.

clean: Tear down all the containers including inactive ones that are
started by docker_run.

build: Compare an image from given dockerfile and rebuild it if they're
different.

ppc patch queue for 2016-05-31

Here's another ppc patch queue.  This batch is all preliminaries
towards two significant features:

1) Full hypervisor-mode support for POWER8
    Patches 1-8 start fixing various bugs with TCG's handling of
    hypervisor mode

2) CPU hotplug support
    Patches 9-12 make some preliminary fixes towards implementing CPU
    hotplug on ppc64 (and other non-x86 platforms).  These patches are
    actually to generic code, not ppc, but are included here with
    Paolo's ACK.
