Linux 内核有约2千万行代码，是最大的开源项目之一。其广泛应用在各个领域，如高性能PC，数据中心，企业服务器，甚至嵌入式系统如Android，Chrome，以及物联网系统。如何保证Linux内核的稳定性健全性非常重要。但是如今的Linux内核项目有近万个开发者，每天产生上万行的代码，我们如何来保证Linux内核的质量呢？

由

Intel推出的0-Day CI（Continuous Integration）解决了这个棘手的问题。0-Day CI是在2012年由开源大拿吴峰光创建并在2013年正式开放使用。吴峰光作为Linux 内核的一名开发者，他观察到现在主流的CI服务都是只发出错误报告，但是由于Linux 内核的特殊性（太多开发人员，太多代码），很难让一个人能够快速地去解决这些问题。

于是，吴峰光发明了0-Day CI。0-Day CI不仅提供错误报告分析，并且还会定位到是哪个commit导致了这个问题，这样相关commit的开发者就会很快地去分析自己的patch找到问题原因。

0-Day CI不仅去测试upstream的代码，而且还会去shift left测试：在开发人员的code被maintainer或upstream接受之前去测试，只要开发人员订阅了0-Day CI的测试服务。正是因为0-Day CI的这种shift left的测试思想，为社区和相关企业减少了很多后期的维护工作。

目

前0-Day CI提供build测试，静态检测和boot测试，同时也集成了业界各种著名的test suites和benchmark进行功能和性能测试。0-Day CI在上线5年以来，得到了广大开源爱好者们的喜爱，著名社区maintainer Andrew Morton曾说：Intel的0-Day Linux kernel测试系统已经对每个内核开发者的生活产生了巨大的影响。Linux创始人Linus Torvalds和x86 maintainer之一Ingo Molnar也给予0-Day CI高度认可。

果说上述功能是0-Day CI的1.0时代，那么今天的0-Day CI已经进入3.0时代。

1.0时代：0-Day CI独特的测试理念大大降低了Linux内核开发人员解决bug的成本，而且帮助Linux内核提高其质量起到了不可估量的作用；

2.0时代：0-Day CI不仅可以测试Linux内核级别的代码，它也延伸到可以测试很多的用户空间的代码测试，如DPDK，NVML (Non-Volatile Memory Library)，甚至也可以对Firmware进行测试，如Sound Of Firmware；

3.0时代：如今0-Day CI不仅被社区使用，而且广泛应用在Intel内部的各个项目里。我们希望0-Day CI能够不断地完善，去解决不同产品的测试需求，甚至去应用如今强大的AI技术去让这个系统更加智能。我们也希望利用0-Day CI产生的庞大数据进行相关分析预测，让Linux的未来更加美好！
