The OPNFV environment requires many kernel modules that are not
part of the default RT kernel environment. This patch adds those
modules back in.

are taken from kernel.org, and rt patch from the rt wiki download page.
During the rebasing, the following patch collided:
Force tick interrupt and get rid of softirq magic(I70131fb85).
Collisions have been removed because its logic was found on the
source already.

We run the cyclictest through yardstick, which will help to setup the
environment.
Environment setup scripts are copied to the yardstick docker images. A
yardstick cyclictest yaml file are also used.

Launch real time guest need special options like lock memory etc. A
script is used to achieved this. We invoke the qemu utility directly
instead of going through middle layer like libvirt, to get better
controll.

This script does the real yardstick works. It downloads the yardstick code,
and run the cyclictest test case.
This scripts is copied by the cyclictest.sh to the container image and
is executed from the yardstick container.
It's based on a script from QiLiang when discussing the integration with
yardstick.

This script download the latest CentOS cloud image and modify it to meet
the test requirement, including remove cloud related script, setup
the ssh keys etc.
It derives from yardstick project, which currently only provide support
to Ubuntu image. If they support CentOS image, we can possibly switch to
them.

To achieve good real time and live migration performance, special setup
is needed on guest environment.
Two scripts are used to setup the guest environment. The guest-setup0.sh
setup the environment that should take effect before the tested kernel is
bringup, including install the kernel rpm, the rt-test package and modify
the grub entries. The guest-setup1.sh setup the environment that takes
effect after the tested kernel is up, like some sysfs entry, interrupt
affinity etc.

The kernel rpm installation on rehl/centos is using grubby to setup the
default kernel entry, so we should not change the grub default set from

There is no rt-tests rpm on centos repo, also we need some special
compile flag to enable the -a parameter. So we try to make the rpm
ourselves. The version is specified as 0.96.
But please notice that the Makefile in the rt-tests tree requires some
key, we have to disable that requirement. So this rpm is only for OPNFV
testing purpose.

Testing KVM4NFV project requires special host environment to get the
best result.
Two scrripts are used to setup the environment. The host-setup0.sh setup
the environment that should take effect before the kernel is bringup,
mostly the grub entries. The host-setup1.sh setup the environment that
takes effect after the kernel is up, like some sysfs entry, interrupt
affinity etc. The host-config provides the configurations.

(Back port from upstream, commit id: 0fd7e098db30e302d27920487f0afec)
The commit 317b0a6d8 fixed an issue which caused by the outdated
env->tsc value, but the fix lead to 'cpu_synchronize_all_states()'
called twice during live migration. The 'cpu_synchronize_all_states()'
takes about 130us for a VM which has 4 vcpus, it's a bit expensive.
Synchronize the whole CPU context just for updating env->tsc is too
wasting, this patch use a new function to update the env->tsc.
Comparing to 'cpu_synchronize_all_states()', it only takes about 20us.

Currently the vfio msi interrupt is kept as IRQ thread, this is not good
for NFV scenerio because in NFV scenerio, we want to inject the interrupt
to the guest asap. A threaded IRQ introduces schedule latency.
However, this change is like a quick and dirty and may bring
potential deadlock, because the spinlock_irqsave() from eventfd_signal()
is preemptible in RT kernel, which should not be held on IRQ context. But
changing it to be raw_spinlock is bad because it will increase the latency
a lot if the eventfd is accessed by user space.
The deadlock should be ok since for vfio MSI handler is purely kernel story
and the lock is a per-eventfd lock and seems no one else is using it for the
vfio msi scenario.

This is a backporting from upstream linux, please refer to
http://marc.info/?t=142904577100001&r=1&w=2 for more information, the
corresponding kernel commit is 0ff53d09642204c64842 (tick: sched: Force
tick interrupt and get rid of softirq magic).
The purpose of this patch is, if a tick_sched interrupt is missed, don't
try to raise softirq, instead, we can simply trigger the timer interrupt.
The reason is, softirq requires context switch and has much higher overhead
than interrupt.
Upstream status: backport 0ff53d09642204c64842

OVS kernel module is important for NFV. The existed kernel config misses
several important kernel configuration, mostly for VxLAN, which is required
by the OVS kernel module.
Also add the OVS as a module, so that user can use it if needed, or replace
it when use the OPNFV patched OVS module.

Because of the patch 3ea3b7fa9af067982f34b of kvm, now the migration_end()
is a time consuming operation, which takes about dozens of milliseconds, and
will prolong VM downtime. Such an operation should be done after migration
completion.
For a VM with 8G RAM, this patch can reduce the VM downtime about 32 ms during
live migration.
