一、开始Rapidio门铃测试之前的准备条件：
1.下载安装rapidio驱动，驱动说明：kernel-rapidio，版本为 1.2.0。
2.测试的应用软件，软件为RapidIO_RRMAP，包含RDMA等应用程序，
版本为：1.2.1
3.两台待测的具备RapidIO的板卡，且已经将两块板卡的RapidIO通过底
板互联，下文将主设备称为Master，从设备称为Slaver。
4.安装驱动，并加载相应的模块。
二、安装好驱动和测试软件后按如下步骤配置：
端修改（在/etc/rapidio目录）配置文件内容如下:
# Configure RapidIO subsystem modules loading
# Uncomment the line below to set enumerator host destination ID on
RapidIO
# network enumerator node (overrides kernel command line option).
# See included documentation for more details.
options rapidio hdid=1234
# Uncomment and edit the line below to change parameters of Tsi721
mport device
# driver. See Documentation/rapidio/ for parameter
descxxxxription.
# options tsi721_mport mbox_sel=0xf dma_sel=0x7f pcie_mrrs=5
dma_txqueue_sz=4096 dma_desc_per_channel=4096
# Uncomment and edit the line below to change parameters of
rio_mport_cdev device
# driver if you want it to use reserved memory range for DMA data
buffers.
options rio_mport_cdev rio_res_mem=0x40000000
rio_res_size=0x10000000
# Uncomment one of the module loading options below (if needed)
# ATTN: If you use kernel mode enumeration please make sure that
switch drivers
# are loaded before an enumeration/discovery process starts.
# Load RapidIO all drivers immediately after rapidio core module was
loaded.
# Use command "echo -1 > /sys/bus/rapidio/scan" to start
enumeration/discovery.
