When I followed the README.md and run command: `python3 ./setup.py test` on CentOS Linux 7, I encountered the following error: ``` running test Searching for onedrivesdk Reading https://pypi.org/simple/onedrivesdk/ Downloading https://files.pythonhosted.org/packages/b3/76/9a3fe5b36079f5c40b33c89ad6f7737e3b8609010a80c9ed24d762ddb93e/onedrivesdk-2.0.tar.gz#sha256=4a1b3cf22570c21f083bea0a0e07b7d3aeab7a72b91abd09372a93b5fca2fba7...

linux_libc_test and linux-syscall test failed in x86_64 Qemu

根据wyf童鞋在zCore上实验，发现一些zCore bug，记录如下： * 在zCore/tests目录下python3 linux_libc_test.py -a x86_64，结果发现每个测试都会跑7～8秒之后段错误然后failed。这些测例在zCore里面手动跑好像没有问题。 > 通过更新Qemu，问题不再出现； * 在zCore里面手动跑linux-syscall/test里面的测例，比如testpipe1，zCore会在处理page fault时报错，打印UserContext然后有可能卡死；运行环境在ubuntu20.04 qemu4.2 for x86_64

Fuchsia startup process analysis

### Fuchsia启动流程分析 0. ZBI镜像中包含Fuchsia内核zircon和RAM disk (bootfs)以及特定硬件信息、内核“command line”； 1. 内核zircon开启用户空间，启动第一个用户进程userboot。 - userboot通过vDSO进行标准系统调用； - userboot elf镜像在内核编译时嵌入到内核中； - 内核将userboot和vDSO都映射到第一个用户进程，然后启动userboot的入口； 2. userboot从ZBI镜像中找到bootfs，LZ4格式解压并复制到一个VMO。从bootfs中启动bootsvc，包括它的动态链接库；下一个启动程序也可以由环境变量“userboot=”指定。 3. bootsvc, usermode加载的第一个程序。提供的系统服务： - bootfs “启动文件系统” 服务，在系统自举后，挂载到”/boot”； - 从bootfs加载的加载服务； bootsvc其中一个主要工作是启动组件管理器component manager；从bootfs启动一个bootsvc.next内核参数指定的程序，默认是bin/component_manager；...
