DPDK for Ubuntu / Debian, let's do it?

[Martinx - ジェームズ]

Awesome!  :-D


I really want to start playing with DPDK, specially when we talk about
OpenStack and Open vSwitch...

Well, to start, I'll share how I'm compiling DPDK-1.8.0 on Ubuntu Trusty
with Linux 3.19.


Complete procedure:


1- Build dependencies:

apt-get install linux-generic-lts-vivid

reboot

apt-get install make coreutils gcc binutils linux-headers-`uname
-r` libc6-dev-i386 libpcap0.8-dev fakeroot


2- Get DPDK and a patch to compile it against Linux 3.19:


mkdir dpdk ; cd dpdk

wget http://dpdk.org/browse/dpdk/snapshot/dpdk-1.8.0.tar.gz

tar xf dpdk-1.8.0.tar.gz

curl -s http://dpdk.org/dev/patchwork/patch/4001/raw/ -o
dpdk-dev-kni-fix-compilation-issue-on-kernel-3.19.patch

cd dpdk-1.8.0

patch -p1 < ../dpdk-dev-kni-fix-compilation-issue-on-kernel-3.19.patch


4- Compiling and installing it to a TMP DESTDIR:


make config T=x86_64-native-linuxapp-gcc

sed -ri 's,(PMD_PCAP=).*,\1y,' build/.config

make

mkdir /tmp/dpdk-1.8.0-destdir

DESTDIR=/tmp/dpdk-1.8.0-destdir fakeroot make install
T=x86_64-native-linuxapp-gcc

ls -l /tmp/dpdk-1.8.0-destdir


Done?!


NOTES:


* If you're building it under a Trusty KVM Virtual Machine, make sure your
VM CPU configuration have all the flags from the host.


- I'll need some kind of direction here, to package it according, mostly
because of:


* What is DPDK? A Library? A Kernel module? User-space drivers, what? Does
it have headers (.h files) (yes, it have)?


Plus, its DESTDIR looks very different from "regular software" after
install... So, how to package it according (to Debian / Ubuntu rules)?


* How we'll call its packages? libdpdk1, libdpdk1-bin, libdpdk1-dev,
dpdk1-kernel-modules (for igb_uio.ko and rte_kni.ko) ... ?


* Do we need to patch DPDK to change the destination paths (to make it
Debian/Ubuntu compliance)?

* Will it compiles on Ubuntu Launchpad PPA infrastructure? I have a
pbuilder env ready but, no package yet.

* I would like to use "git-buildpackage" and host our "dpdk-1.8.0/debian"
subdir on Github. I like Launchpad but dislike bazaar.


BTW, I'm starting with DPDK-1.8.0 because DPDK-2.0.0 have some problems,
also, I think that it will be a good start pointing.


Also, can we learn something from DPDK Fedora / RedHat RPM package? They
already have it.

http://rpmfind.net/linux/rpm2html/search.php?query=dpdk - Not sure about
its quality, since it is for, you know, RedHat...


Hope to hear more from you guys!

Best,
Thiago
