Daniel Verkamp 9ea5194634 build: simplify dependency generation 
Modern GCC and Clang versions can generate .d files without needing the
complex sequence of sed scripts that we currently use.

Also adjust the .o rule so the .d file is regenerated if it gets
deleted.

Also make the .o depend on all of the Makefile fragments in
$(MAKEFILE_LIST) so that it is rebuilt if the Makefile is changed.

Storage Performance Development Kit

Build Status

SPDK on 01.org

The Storage Performance Development Kit (SPDK) provides a set of tools and libraries for writing high performance, scalable, user-mode storage applications. It achieves high performance by moving all of the necessary drivers into userspace and operating in a polled mode instead of relying on interrupts, which avoids kernel context switches and eliminates interrupt handling overhead.

Porting Guide

Prerequisites

To build SPDK, some dependencies must be installed.

Fedora/CentOS:

  • gcc
  • libpciaccess-devel
  • CUnit-devel

Ubuntu/Debian:

  • gcc
  • libpciaccess-dev
  • make
  • libcunit1-dev

FreeBSD:

  • gcc
  • libpciaccess
  • gmake
  • cunit

Additionally, DPDK is required.

1) cd /path/to/spdk
2) wget http://dpdk.org/browse/dpdk/snapshot/dpdk-2.1.0.tar.gz
3) tar xfz dpdk-2.1.0.tar.gz
4) cd dpdk-2.1.0

Linux:

5) make install T=x86_64-native-linuxapp-gcc

FreeBSD:

5) gmake install T=x86_64-native-bsdapp-clang

Building

Once the prerequisites are installed, run 'make' within the SPDK directory to build the SPDK libraries and examples.

make DPDK_DIR=/path/to/dpdk

If you followed the instructions above for building DPDK:

Linux:

make DPDK_DIR=`pwd`/dpdk-2.1.0/x86_64-native-linuxapp-gcc

FreeBSD:

gmake DPDK_DIR=`pwd`/dpdk-2.1.0/x86_64-native-bsdapp-clang

Hugepages and Device Binding

Before running an SPDK application, some hugepages must be allocated and any NVMe devices must be unbound from the native NVMe kernel driver. SPDK includes scripts to automate this process on both Linux and FreeBSD.

1) scripts/configure_hugepages.sh
2) scripts/unbind_nvme.sh
