Hi DPDK developers,

I'd like to contribute a new EAL to support our open-sourced operating system called "OSv".
It is a new operating system build from scratch for cloud computing, to run application faster with lower footprint on IaaS.
Unlike general propose OS, it is a library OS designed to run single application per one instance, everything run in kernel mode, single memory space.
It's not using Linux kernel but has compatibility with Linux application, not perfect but we already supported various applications such as Cassandra, memcached, Redis, etc.

In DPDK case, PMDs can access devices directly, without kernel driver help.
At this point I haven't enough optimized performance of the EAL yet, but it has potential to get better performance than Linux with fewer resources.

OSv web site: http://osv.io

Since OSv is written in C++, we need to write OSv EAL in C++.
To do so, we need to compile .cc files by $(CXX).

This patch does not contain diff for clang and icc, but OSv EAL does not supported these toolchain, this is enough for now.

Adding OSv support.
Based on Linux/FreeBSD EAL, but calling OSv kernel APIs to access devices, allocate contiguous memory, etc.

I presume you intend for this to get merged during the 2.1 release?

We have an application repository for OSv, I'll add DPDK to deploy it
easier:
https://github.com/cloudius-systems/osv-apps
And we will add DPDK building instructions on OSv wiki:
https://github.com/cloudius-systems/osv/wiki

Since Linux and FreeBSD has "Getting Started Guide", probably I need to add
OSv version too?

Ah, then do we need to add a check to prevent trying to configure shared
libraries then?

Since OSv is written in C++, we need to write OSv EAL in C++.
To do so, we need to compile .cc files by $(CXX).

This patch does not contain diff for clang and icc, but OSv EAL does not supported these toolchain, this is enough for now.

+.. _building_from_source:
+
+Compiling the DPDK Target from Source
+=====================================
+
+System Requirements
+-------------------
+
+To building DPDK for OSv, you will need to use Linux/x86_64 with g++ 4.8 or later.
+
+Install the DPDK and Browse Sources
+-----------------------------------
+
+First, uncompress the archive and move to the DPDK source directory:
+
+.. code-block:: console
+
+    [user@host ~]$ unzip DPDK-<version>zip
+    [user@host ~]$ cd DPDK-<version>
+    [user@host DPDK]$ ls
+    app/ config/ examples/ lib/ LICENSE.GPL LICENSE.LGPL Makefile mk/ scripts/ tools/
+
+The DPDK is composed of several directories:
+
+*   lib: Source code of DPDK libraries
+
+*   app: Source code of DPDK applications (automatic tests)
+
+*   examples: Source code of DPDK applications
+
+*   config, tools, scripts, mk: Framework-related makefiles, scripts and configuration
+
+Install Capstan
+--------------------------------------------
+
+Before start building VM image, you need to install Capstan*:
+
+`http://osv.io/capstan/`
+
+.. code-block:: console
+
+    [user@host ~]$ curl https://raw.githubusercontent.com/cloudius-systems/capstan/master/scripts/download | bash
+
+Build DPDK for OSv VM image
+--------------------------------------------
+
+Build VM image using Capstan:
+
+.. code-block:: console
+
+    [user@host ~]$ cd DPDK-<version>/lib/librte_eal/osvapp/capstan/
+    [user@host capstan]$ capstan build osv-dpdk

+Run DPDK for OSv VM image
+--------------------------------------------
+
+Run VM image using Capstan:
+
+.. code-block:: console
+
+    [user@host ~]$ capstan run osv-dpdk
+    Created instance: osv-dpdk

+
+Run another sample applications
+--------------------------------------------
+
+Delete osv-dpdk instance at first if you already deployed it on Capstan:
+
+.. code-block:: console
+
+    [user@host ~]$ cd DPDK-<version>/lib/librte_eal/osvapp/capstan/
+    [user@host capstan]$ capstan delete osv-dpdk
+    Deleted instance: osv-dpdk
+
+Then you need to open Capstanfile on a editor, modify cmdline field:
+
+.. code-block:: console
+
+    base: cloudius/osv-base
+
+    cmdline: /l2fwd --no-shconf -c 3 -n 2 --log-level 8 -m 768 -- -p 3
+
+    build: ./GET
+
+Build VM image again:
+
+.. code-block:: console
+
+    [user@host capstan]$ capstan build osv-dpdk
+    Building osv-dpdk...
+    Downloading cloudius/osv-base/index.yaml...

+    Uploading files...
+    10 / 10 [============================================================] 100.00 %
+
+.. note::
+
+	You can use another name for new VM instance.
+	On that case, you don't have to delete existing instance.
+
+Export VM image to libvirt
+--------------------------------------------
+
+Packet forwarding application(such as l2fwd or l3fwd) requires multiple vNICs with multiple bridges, but Capstan does not have a way to configure such network.
+
+To do so, you can export VM image to libvirt by using virt-install:
+
+.. code-block:: console
+
+    [user@host ~]$ sudo virt-install --import --noreboot --name=osv-dpdk --ram=4096 --vcpus=2 --disk path=/home/user/.capstan/repository/osv-dpdk/osv-dpdk.qemu,bus=virtio --os-variant=none --accelerate --network=network:default,model=virtio --network=network:net2,model=virtio --serial pty --cpu host --rng=/dev/random
+
+    WARNING  Graphics requested but DISPLAY is not set. Not running virt-viewer.

+
+Compiling and Running Sample Applications
+=========================================
+
+The chapter describes how to compile and run applications in a DPDK
+environment. It also provides a pointer to where sample applications are stored.
+
+Running a Sample Application
+----------------------------
+
+The following is the list of options that can be given to the EAL:
+
+.. code-block:: console
+
+    ./rte-app -c COREMASK -n NUM [-b <domain:bus:devid.func>] [-r NUM] [-v] [--proc-type <primary|secondary|auto>]
+
+.. note::
+
+    EAL has a common interface between all operating systems and is based on the
+    Linux* notation for PCI devices. For example, a FreeBSD* device selector of
+    pci0:2:0:1 is referred to as 02:00.1 in EAL.
+
+The EAL options for FreeBSD* are as follows:
+
+*   -c COREMASK
+    : A hexadecimal bit mask of the cores to run on.  Note that core numbering
+    can change between platforms and should be determined beforehand.
+
+*   -n NUM
+    : Number of memory channels per processor socket.
+
+*   -b <domain:bus:devid.func>
+    : blacklisting of ports; prevent EAL from using specified PCI device
+    (multiple -b options are allowed).
+
+*   --use-device
+    : use the specified ethernet device(s) only.  Use comma-separate
+    <[domain:]bus:devid.func> values. Cannot be used with -b option.
+
+*   -r NUM
+    : Number of memory ranks.
+
+*   -v
+    : Display version information on startup.
+
+*   --proc-type
+    : The type of process instance.
+
+Other options, specific to Linux* and are not supported under FreeBSD* are as follows:
+
+*   socket-mem
+    : Memory to allocate from hugepages on specific sockets.
+
+*   --huge-dir
+    : The directory where hugetlbfs is mounted.
+
+*   --file-prefix
+    : The prefix text used for hugepage filenames.
+
+*   -m MB
+    : Memory to allocate from hugepages, regardless of processor socket.
+    It is recommended that --socket-mem be used instead of this option.
+
+The -c and the -n options are mandatory; the others are optional.
+
+Edit cmdline on Capstanfile, then rebuild and run VM instance as follows
+(assuming the platform has four memory channels, and that cores 0-3
+are present and are to be used for running the application):
+
+.. code-block:: console
+

I forgot to copied rte_eal_version.map, added on new patchset.
OSv supports shared libraries, but I found that DPDK shared libraries
causes an error on OSv:
https://github.com/cloudius-systems/osv/issues/599
I'll fix it shortly.

I understand removing symbols that you don't support, but why are you adding the
vdev, pci and parsing symbols?  I don't see you using them anywhere in your
code...

This was because I copied rte_eal_version.map from linuxapp, but git
format-patch generated diff from bsdapp.
But osvapp don't have these symbols, so I dropped these lines.
Please check v3 patchset which I just posted.
