所有工具和参考设计使用2021.2。编译和测试X86主机(Host)的操作系统是CentOS 7.9.2009。测试的单板是VCK190,测试的是CPM QDMA。
记录和脚本里的井号,或者第一行开始处的井号,由于和Markdown语法有冲突,替换成了星号。有些软件打印的记录非常长,于是把其中部分内容替换成了“......”。
同事马鸿伟(hongweim@xilinx.com)在测试过程中提供了很大的帮助,非常感谢。
X86 PCIe Host侧的Linux内核驱动:
https://github.com/Xilinx/dma_ip_drivers/QDMA/linux-kernel
简单来说,使用命令“make”可以编译,使用命令“sudo make install”可以安装驱动。测试中,使用了2020.1分支。
QDMA Subsystem for PCI Express v4.0 Product Guide PG302 (v4.0) January 5, 2022
X86 PCIe Host侧的Linux内核驱动里有简要说明。
https://github.com/Xilinx/dma_ip_drivers/tree/master/QDMA/linux-kernel/docs
xilinx.github.io有更详细的文档,比较全面。
https://xilinx.github.io/dma_ip_drivers/2020.1/linux-kernel/html/index.html
如果只使用PCIe 物理功能(PF),不使用虚拟功能(VF),QDMA的总体测试流程如下。
查找PCIe设备
确保Linux加载QDMA驱动
创建QDMA队列
启动QDMA队列
启动QDMA传输
停止QDMA队列
删除QDMA队列
操作队列时,需要提供队列的从0开始编号的序号(index)。另外,C2H和H2C分开计数序号(index),也就是C2H和H2C可以使用相同的数序号(index)。
dma-ctl是测试的配置工具,可以列出qdma设备、队列;也可以创建、删除、启动、停止队列。下面是它的帮助信息。
Usage: dma-ctl [dev|qdma[vf]
dev [operation]: system wide FPGA operations

下面是列出qdma设备的例子。
[root@localhost pcie]# dma-ctl dev list
qdma01000 0000:01:00.0 max QP: 32, 0~31
下面是qdma队列操作的例子。
[root@localhost pcie]# ls /dev/qdma*
ls: cannot access /dev/qdma*: No such file or directory
[root@localhost pcie]# dma-ctl qdma01000 q list
Zero Qs
Test Xilinx PCIe QDMA h2c channel.
[root@localhost pcie]# dma-ctl qdma01000 q add idx 0 mode mm dir h2c
qdma01000-MM-0 H2C added.
Added 1 Queues.
[root@localhost pcie]# ls /dev/qdma*
/dev/qdma01000-MM-0
[root@localhost pcie]# dma-ctl qdma01000 q start idx 0 dir h2c
dma-ctl: Info: Default ring size set to 2048
1 Queues started, idx 0 ~ 0.
[root@localhost pcie]# dma-ctl qdma01000 q list
H2C Q: 1, C2H Q: 0, CMPT Q 0.
qdma01000-MM-0 H2C online
hw_ID 0, thp ?, desc 0xffff98fe5f750000/0x1f750000, 1536
[root@localhost pcie]# dma-ctl qdma01000 q stop idx 0 dir h2c
Stopped Queues 0 -> 0.
[root@localhost pcie]# dma-ctl qdma01000 q del idx 0 dir h2c
Deleted Queues 0 -> 0.
[root@localhost pcie]# dma-ctl qdma01000 q list
Zero Qs
[root@localhost pcie]# dma-ctl qdma01000 stat
qdma01000:statistics
Total MM H2C packets processed = 34000
Total MM C2H packets processed = 17
Total ST H2C packets processed = 0
Total ST C2H packets processed = 0
Min Ping Pong Latency = 0
Max Ping Pong Latency = 0
Avg Ping Pong Latency = 0
[root@localhost pcie]# ls /dev/qdma*
ls: cannot access /dev/qdma*: No such file or directory
注意,只有在有qdma队列的时候,在系统目录“/dev/”下,才有qdma设备,执行命令“ls /dev/qdma*”才有设备节点。
重复添加同样序号的队列,会报告错误“Queue compatibility check failed against existing queues”。应该删除同样序号的队列后,才添加同样序号的队列。
[root@localhost pcie]# dma-ctl qdma01000 q add idx 0 mode mm dir h2c
qdma01000-MM-0 H2C added.
Added 1 Queues.
[root@localhost pcie]# dma-ctl qdma01000 q add idx 0 mode mm dir h2c
Queue compatibility check failed against existing queues
重复启动同样序号的队列,会报告错误“Error. Required Q state=cfg'ed, Current Q state=online”。应该停止同样序号的队列后,才启动同样序号的队列。
[root@localhost pcie]# dma-ctl qdma01000 q start idx 0 dir h2c
dma-ctl: Info: Default ring size set to 2048
1 Queues started, idx 0 ~ 0.
[root@localhost pcie]# dma-ctl qdma01000 q start idx 0 dir h2c

dma-to-device可以用于发起X86 Host到PCIe Card数据传输测试的工具,下面是它的帮助信息。
[hankf@localhost pcie]$ dma-to-device --help
dma-to-device
usage: dma-to-device [OPTIONS]
Write via SGDMA, optionally read input from a file.
-d (--device) device (defaults to /dev/qdma01000-MM-0)
-a (--address) the start address on the AXI bus
-s (--size) size of a single transfer in bytes, default 32,
-o (--offset) page offset of transfer
-c (--count) number of transfers, default 1
-f (--data infile) filename to read the data from.
-w (--data outfile) filename to write the data of the transfers
-h (--help) print usage help and exit

下面是在启动队列后,运行命令“dma-to-device”的信息。
[root@localhost pcie]# dma-to-device -d /dev/qdma01000-MM-0 -s 65536 -c 1000
** Average BW = 65536, 3981.411377
如果设备没有启动,虽然也有设备节点,dma-to-device会执行失败,输出信息如下:
[root@localhost pcie]# ls /dev/qdma*
/dev/qdma01000-MM-0
[root@localhost pcie]# dma-to-device -d /dev/qdma01000-MM-0 -s 4096 -c 1000
/dev/qdma01000-MM-0, W off 0x0, 0x1000 failed -1.

dma-from-device可以用于发起X86 Host到PCIe Card数据传输测试的工具,下面是它的帮助信息。
[root@localhost qdma]# dma-from-device --help
dma-from-device
usage: dma-from-device [OPTIONS]

-d (--device) device (defaults to /dev/qdma01000-MM-0)
-a (--address) the start address on the AXI bus
-s (--size) size of a single transfer in bytes, default 32.
-o (--offset) page offset of transfer
-c (--count) number of transfers, default is 1.
-f (--file) file to write the data of the transfers
-h (--help) print usage help and exit
-v (--verbose) verbose output
下面是在启动队列后,运行命令“dma-from-device”的信息。
[root@localhost pcie]# ls /dev/qdma*
/dev/qdma01000-MM-0
[root@localhost pcie]# dma-from-device -d /dev/qdma01000-MM-0 -s 65536
** Average BW = 65536, 1039.313599
为了简化后续操作,把相关命令写在了一个Linux脚本文件中。注意,这只是一个简化的脚本,没有错误处理。如果PCIe设备不存在,或者多次运行,会有错误信息。请根据实际情况处理。多次运行时,可以重复创建队列时的错误信息。
