1.1. 介绍

Python3.x + Graphviz自动化绘制C语言 函数调用关系图、结构体关系图
已使用Cython将Python代码转化为c，可以自行编译安装

1.2. 软件架构

软件架构说明

1.3. 安装教程

1. sudo -H pip3 install filetype pygraphviz
2. sudo -H pip3 install Cython setuptools
3. sudo apt install graphviz
4. cd cview
5. make all
6. sudo -H make install

1.4. 使用说明

1. 生成源文件

• 函数调用关系图
  只支持ARM
  对编译生成的文件进行反汇编

aarch64-linux-gnu-objdump -d vmlinux > vmlinux.dis

• 结构体关系图
  在编译Makefile中，CFLAGS选项中添加-save-temps=obj，再进行编译

KBUILD_CFLAGS   := -Wall -Wundef -Werror=strict-prototypes -Wno-trigraphs \
                   -fno-strict-aliasing -fno-common -fshort-wchar -fno-PIE \
                   -Werror=implicit-function-declaration -Werror=implicit-int \
                   -Wno-format-security \
                   -std=gnu89 -save-temps=obj

1. 解析文件
   解析文件实例

#!/usr/bin/env python3
# -*- coding:utf-8 -*-

import os
import sys
import cview
import time

def main(argv):

    db_path = '../../test.db'

    t_start = time.time()
    # step1: init
    test = cview.CView()
    os.remove(db_path)
    test.load_db(db_path)

    # step2: parser file
    test.parse_file('Func', 'function', '../../vmlinux.dis')
    test.parse_file('Data', 'struct', '../../exit.i')

    test.db.table_info()

    t_end = time.time()
    print('use {t_use:.2f}s'.format(t_use=(t_end - t_start)))


if __name__ == '__main__':
    main(sys.argv[0:])

2. 生成关系图
   关系图实例

#!/usr/bin/env python3
# -*- coding:utf-8 -*-

import os
import sys
import cview
import time


def main(argv):

    db_path = '../../test.db'

    t_start = time.time()
    # step1: init and load database
    test = cview.CView()
    test.load_db(db_path)

    test.db.table_info()

    # step2: the first table
    test.db.set_table('function')
    node_list = {
        'start_kernel',
        'kernel_init',
    }
    test.add_nodes_from(node_list)
    test.tree('kernel_init', 1, 2)
    test.build(random=False)

    # step3: the second table
    test.db.set_table('struct')
    node_list = {
        'struct zone',
    }
    test.add_nodes_from(node_list)
    test.tree('struct page', 1, 3)
    test.build(random=False)

    # step4: the end
    test.write('./test.gv')

    t_end = time.time()
    print('use {t_use:.2f}s'.format(t_use=(t_end - t_start)))

if __name__ == '__main__':
    main(sys.argv[0:])
