Daniel Verkamp f19d1faedd build: disable assert() when building for release 
Set -DNDEBUG to make assert() a no-op.  Since nvme_assert() is just an
alias for assert(), this controls compilation of nvme_assert as well.

Storage Performance Development Kit

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.

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
