1.fpga_check.py

# fpga_check.py 为检查FPGA版本脚本。
# 将fpga_check.py 拷贝到perfq_app所在的目录下执行。
#（/commit_code/ali_fpga/software/user/cli/perfq_app/）该脚本运行于OS下。
# 使用命令 python fpga_check.py b1  运行脚本。(参数1为 PCIE bus，根据实际情况传参)。

# coding = utf-8
import os
import sys
import subprocess

char_0 = './perfq_app -b 0000:'
char_1 = sys.argv[1]
char_2 = ':00.0 -o -R 0x1000'
command = char_0 + char_1 + char_2
print(command)
FPGA_Version = 'PIO Reg:0x1000 value:0x000001d2'
Read_Version = ''
var = subprocess.check_output(command, shell=True).decode('utf-8')

fp = open('fpga_test.txt', 'w')
fp.write(var)
fp.close()

fp = open('fpga_test.txt', 'r')
sample = fp.readlines()
for line in sample:
    line = line.strip()
    if 'Reg:0x1000' in line:
        Read_Version = line
fp.close()
os.system('sudo rm fpga_test.txt')

if Read_Version == FPGA_Version:
    print('FPGA Version is ok !')
else:
    print(var)
    print('Please check the version !')

2.pcie_check.py

# pcie_check.py脚本是检查PCIE的Corporation Device 、Region 0、Region 2、LnkCap、LnkSta信息。
# 注意板卡所在插槽位置。使用命令python pcie_check.py  b1运行脚本。
# b1为PCIE bus，根据实际情况传参。运行命令屏幕会显示相应需要检查信息的正确和错误信息。

# coding = utf-8
import os
import sys

char_0 = 'lspci -vvv -s '
char_1 = sys.argv[1]
char_2 = ':00.0 > FPGA_lspci_info.txt'
command = char_0 + char_1 + char_2
os.system(command)

Altera_Corporation_Device = 'Altera Corporation Device 0000'
Region_0 = 'size=4M'
Region_2 = 'size=16K'
LnkCap = 'Speed 16GT/s, Width x16'
LnkSta_0 = 'Speed 16GT/s'
LnkSta_1 = 'Width x16'

var = [0] * 10
i = 0
fp = open("FPGA_lspci_info.txt", "r")
sample = fp.readlines()

for line in sample:
    line = line.strip()
    if 'Unassigned class' in line:
        var[i] = line
        i = i + 1
    if 'Region 0: Memory' in line:
        var[i] = line
        i = i + 1
    if 'Region 2: Memory' in line:
        var[i] = line
        i = i + 1
    if 'LnkCap:' in line:
        var[i] = line
        i = i + 1
    if 'LnkSta:' in line:
        var[i] = line
        i = i + 1
fp.close()


if Altera_Corporation_Device in var[0]:
    print('Altera Corporation Device PASS')
else:
    print('ERROR')

if Region_0 in var[1]:
    print('Region 0 PASS')
else:
    print('ERROR')

if Region_2 in var[2]:
    print('Region 2 PASS')
else:
    print('ERROR')

if LnkCap in var[3]:
    print('LnkCap PASS')
else:
    print('ERROR')

if LnkSta_0 in var[4] and LnkSta_1 in var[4]:
    print('LnkSta PASS')
else:
    print('ERROR')
os.system('sudo rm FPGA_lspci_info.txt')

3.pcie.py

# pcie.py脚本是对PCIE通道的性能测试，主要是对FPGA寄存器读写压力测试，从而对PCIE性能进行测试。
# 请确保目录 ~/commit_code/ali_fpga/software/user/cli/perfq_app/ 目录下存在perfq_app 工具。
# 在os下将脚本文件拷到perfq_app所在的目录下使用命令 python pcie.py 参数1  参数2 运行脚本（参数1为板卡所在的号码如 b3 , 参数2为读写的次数）。 
# 运行脚本，屏幕会显示相应的错误和正确信息。
