 #### Description
+
 libkperf is a lightweight performance collection library on linux, that enables developers to perform performance collection in an API fashion. libkperf provides performance data in memory and allows develops to process data directly, reducing overhead of writing and reading perf.data.
 
 #### Supported CPU Architectures
+
 - Kunpeng
 
 #### Supported OS
+
 - openEuler
 - OpenCloudOS
 - TencentOS

 - CentOS
 
 #### Build
+
 Minimum required GCC version:
+
 - gcc-4.8.5 and glibc-2.17.
 
 Minimum required Python version:
+
 - python-3.7.
 
 To build a library with C API:
+
 ```shell
 git clone --recurse-submodules https://gitee.com/openeuler/libkperf.git
 cd libkperf
 bash build.sh install_path=/path/to/install
 ```
+
 Note:
 
 - If the compilation error message indicates that numa.h file is missing, you need to first install the corresponding numactl-devel package.
 - If you encounter a CMake error related to 'Found PythonInterp' during compilation and linking, you need to first install the required python3-devel package.
 
 To build a library with debug version:
+
 ```shell
 bash build.sh install_path=/path/to/install buildType=debug
 ```
 
 To build a python package:
+
 ```shell
 bash build.sh install_path=/path/to/install python=true
 ```
 
 To uninstall python package:
+
 ```shell
 python3 -m pip uninstall -y libkperf
 ```

 int len = PmuRead(pd, &data);

 ### SPE Sampling
+
 libkperf提供SPE采样模式，类似于perf record的如下命令：

 - PmuAttr.symbolMode如果等于NO_SYMBOL_RESOLVE，那么PmuData的stack是空指针。

+
 ```mermaid
 graph TD
 a(主线程) --perf stat--> b(创建线程)
 b --> c(子线程)
 c --end perf--> d(子线程退出)
 ```
+
 考虑上面的场景：用perf stat对进程采集，之后进程创建了子线程，采集一段事件后，停止perf。
 查看采集结果，perf只会显示主线程的采集结果，而无法看到子线程的结果：count = count(main thread) + count(thread). perf把子线程的数据聚合到了主线程上。
 
 libkperf提供了采集子线程的能力。如果想要在上面场景中获取子线程的计数，可以把PmuAttr.incluceNewFork设置为1.
+
 ```c++
 // c++代码示例
 attr.includeNewFork = 1;
 ```
+
 ```python
 # python代码示例
 pmu_attr = kperf.PmuAttr(evtList=evtList, includeNewFork=True)

 然后，通过PmuRead获取到的PmuData，便能包含子线程计数信息了。
 注意，该功能是针对Counting模式，因为Sampling和SPE Sampling本身就会采集子线程的数据。
