Daniel Verkamp c8f27b9e6e nvme: mark a few more functions static 
nvme_qpair_submit_tracker() and nvme_qpair_manual_complete_request() are
only used from within nvme_qpair.c, so they can be static.

nvme_qpair_submit_tracker() is moved up to avoid needing a declaration
(no other code change).

nvme_ctrlr_hw_reset() is only used from within nvme_ctrlr.c, so it can
be static.

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=./dpdk-2.1.0/x86_64-native-linuxapp-gcc

FreeBSD:

gmake DPDK_DIR=./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 and I/OAT devices must be unbound from the native kernel drivers. SPDK includes scripts to automate this process on both Linux and FreeBSD.

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