Description

基本输入输出***BIOS配置项的配置方法及服务器
本申请要求于2022年11月07日提交国家知识产权局、申请号为202211385564.2、申请名称为“基本输入输出***BIOS配置项的配置方法及服务器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及基本输入输出***技术领域，尤其涉及一种基本输入输出***BIOS配置项的配置方法及服务器。
背景技术
基本输入输出***(basic input output system，BIOS)是固化在主板上的BIOS芯片中的程序，主要功能是为服务器提供硬件设置和控制。此外，BIOS还向用户提供了多种配置项，通过修改这些配置项所配置的内容，可以控制服务器的运行状态。
相关技术中，服务器的操作***(operating system，OS)运行后，如果想要修改BIOS配置项的配置内容，需要重启***，从而在BIOS运行过程中修改BIOS配置项的配置内容。之后，再次重启***，由BIOS执行修改操作，以使BIOS配置项的修改生效。
也就是说，OS运行后，若想要修改BIOS配置项的配置内容，需要重启两次服务器才能使BIOS配置项的修改生效。这样，势必会造成服务器所运行的业务中断，严重影响了服务器的服务性能。
发明内容
本申请实施例提供一种基本输入输出***BIOS配置项的配置方法及服务器，能够在不重启***的情况下修改BIOS配置项，有助于避免服务器所运行的业务被中断。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种基本输入输出***BIOS配置项的配置方法，用于服务器，服务器包括中央处理器CPU和带外控制器，该方法由带外控制器执行；该方法包括：确定BIOS配置项中的目标配置项的待配置内容；目标配置项为BIOS配置项中支持在线修改的配置项；若CPU运行操作***OS，向CPU发送***管理中断信号；其中，***管理中断信号用于指示：CPU由运行OS转换为运行BIOS；CPU运行BIOS的过程中，CPU获取待配置内容，并将目标配置项配置的内容配置为待配置内容；以及若CPU完成目标配置项的配置，CPU恢复运行OS。
在该方案中，带外控制器在确定目标配置项的待配置内容后，若CPU运行OS，则向CPU发送***管理中断信号，实现指示CPU由运行OS转换为运行BIOS，并在CPU运行BIOS的过程中，将目标配置项配置的内容配置为待配置内容，从而实现修改目标配置项的配置内容。由于***管理中断信号还能够指示在CPU完成目标配置项的配置后，CPU恢复运行OS，因此，能够在不重启***的情况下修改目标配置项，从而实现了在保持服务器的业务连续在线的情况下修改目标配置项。
基于此，一方面，在发现BIOS芯片或者BIOS特性有缺陷时，则可以在保持服务器的业务连续在线的情况下修改目标配置项的待配置内容，实现关闭不适用或者有缺陷的特性。另一方面，还可以根据业务处于波峰工作状态或波谷工作状态，对目标配置项进行重新配置，例如，业务处于波峰工作状态运行，通过修改目标配置项的待配置内容，使待配置内容指示关闭节能特性，使得服务器运行于高性能模式。业务处于波谷工作状态，通过修改目标配置项的待配置内容，使待配置内容指示开启节能特性，从而达到节能减排效果。此外，由于服务器的不同运行场景对能效调优的需求存在差异，因此，还可以根据服务器的当 前运行场景，修改目标配置项的待配置内容，使待配置内容指示的能效调优类型与当前运行场景相匹配，实现在服务器的业务持续在线的情况下，为服务器配置与当前运行场景匹配的能效调优模式。
在一种可能的实现方式中，确定BIOS配置项中的目标配置项的待配置内容，包括：向终端设备发送界面配置信息；界面配置信息用于终端设备显示配置界面，配置界面包括目标配置项；接收终端设备发送的目标配置项的待配置内容；待配置内容是终端设备响应于对配置界面上的目标配置项的配置操作确定的。
在该实现方式中，提供了一种确定目标配置项的待配置内容的具体实现方式。该方式中，带外控制器通过向终端设备发送界面配置信息，使得终端设备可以显示目标配置项，这样，终端设备就可以通过对目标配置项的配置操作，确定目标配置项的待配置内容。之后，带外控制器通过接收终端设备返回的待配置内容，实现确定目标配置项的待配置内容。该方式中，无需用户了解编程语言，只需用户在配置界面上进行配置操作，带外控制器即可实现确定目标配置项的待配置内容，实现过程简单、方便，对用户的要求较低。
另一种可能的实现方式中，确定BIOS配置项中的目标配置项的待配置内容，包括：响应于终端设备的请求，向终端设备发送目标配置项的标识；接收终端设备发送的待配置内容；待配置内容是终端设备基于目标配置项的标识确定的。
在该实现方式中，提供了一种确定目标配置项的待配置内容的具体实现方式。该方式中，带外控制器通过向终端设备发送目标配置项的标识，使得用户可以了解BIOS配置项中的哪些配置项支持在线修改。之后，带外控制器通过接收终端设备返回的待配置内容，实现确定目标配置项的待配置内容。该方式中，带外控制器只需向终端设备发送目标配置项的标识，即可实现确定目标配置项的待配置内容，简化了带外控制器确定目标配置项的待配置内容的控制逻辑，有助于降低对带外控制器的要求。
另一种可能的实现方式中，该方法还包括：接收CPU发送的配置项集合；配置项集合为当前版本的BIOS支持在线修改的配置项的集合，配置项集合包括目标配置项，配置项集合是在BIOS启动过程中发送的。
在该实现方式中，BIOS启动过程中，带外控制器接收CPU发送的当前版本的BIOS支持在线修改的配置项的集合，一方面，能够使得带外控制器可以基于该配置项集合，确定BIOS配置项中哪些配置项支持在线修改。另一方面，由于配置项集合为当前版本的BIOS支持在线修改的配置项的集合，因此，有助于保证所确定的目标配置项与当前版本的BIOS相匹配。
另一种可能的实现方式中，该方法还包括：接收CPU返回的目标选项的配置结果；配置结果用于指示目标配置项配置成功或配置失败，配置结果是CPU运行BIOS的过程中发送的。
在该实现方式中，CPU运行BIOS的过程中，带外控制器通过接收CPU返回的配置结果，确定目标配置项是否已更新为待配置内容，这样，有助于带外控制器及时掌握目标配置项的配置内容是否发生更新。
另一种可能的实现方式中，服务器还包括BIOS芯片，BIOS芯片中存储有BIOS配置项的配置内容；该方法还包括：接收CPU发送的获取请求；获取请求是在BIOS启动过程发送的，获取请求用于请求目标配置项所配置的内容；若配置结果指示目标配置项配置成功，向CPU发送待配置内容；待配置内容用于将BIOS芯片中的目标配置项的配置内容修改为待配置内容。
在该实现方式中，服务器重启时，在BIOS启动过程中，带外控制器基于CPU的获取请求，向CPU返回待配置内容，使得CPU可以将BIOS芯片中的目标配置项的配置内容修改为待配置内容。这样，BIOS就可以基于BIOS芯片中的目标配置项所配置的待配置内容，为服务器进行配置设置，从而使得服务器重启后，可以自动恢复到重启前的配置，不必再重新进行配置。
第二方面，提供了一种基本输入输出***BIOS配置项的配置方法，用于服务器，服务器包括中央成处理器CPU和带外控制器，该方法由CPU执行；该方法包括：若CPU运行操作***OS，CPU接收***管理中断信号，并基于***管理中断信号执行以下操作：CPU由运行OS转换为运行BIOS；CPU运行BIOS 的过程中，CPU向带外控制器获取目标配置项的待配置内容，并将目标配置项的内容配置为待配置内容；目标配置项为BIOS配置项中支持在线修改的配置项；若CPU完成目标配置项的配置，CPU恢复运行OS。
在该方案中，若CPU运行OS，CPU接收带外控制器发送的***管理中断信号，并执行该***管理中断信号所指示的由运行OS转换为运行BIOS，向带外控制器获取目标配置项的待配置内容，并将目标配置项的内容配置为待配置内容，从而实现修改目标配置项的配置内容。由于***管理中断信号还指示在CPU完成目标配置项的配置后，CPU恢复运行OS，因此，能够在不重启***的情况下修改目标配置项所配置的内容，从而实现了在保持服务器的业务连续在线的情况下修改目标配置项。
需要说明的，第二方面的其他技术效果可以参考第一方面，此处不再细述。
在一种可能的实现方式中，在BIOS启动过程中，该方法还包括：CPU向带外控制器发送配置项集合；配置项集合为当前版本的BIOS支持在线修改的配置项的集合；配置项集合包括目标配置项。
在该实现方式中，在BIOS启动过程中，CPU通过向带外控制器发送配置项集合，一方面，能够使得带外控制器可以基于该配置项集合，确定BIOS配置项中的哪些配置项支持在线修改。另一方面，由于配置项集合为当前版本的BIOS支持在线修改的配置项的集合，因此，有助于提高所确定的目标配置项与当前版本的BIOS相匹配。
另一种可能的实现方式中，CPU运行BIOS的过程中，该方法还包括：CPU向带外控制器发送目标配置项的配置结果；配置结果用于指示目标配置项配置成功或配置失败。
在该实现方式中，CPU运行BIOS的过程中，CPU通过向带外控制器发送目标配置项的配置结果，使得带外控制器可以通过该配置结果，确定目标配置项是否更新了配置内容，这样，有助于带外控制器及时掌握目标配置项的配置内容是否发生更新。
另一种可能的实现方式中，服务器还包括BIOS芯片，BIOS芯片中存储有BIOS配置项的配置内容；在BIOS启动过程中，该方法还包括：CPU向带外控制器发送获取请求；获取请求用于请求目标配置项所配置的内容；CPU接收带外控制器返回的待配置内容；CPU将BIOS芯片中的目标配置项的配置内容修改为待配置内容。
在该实现方式中，服务器重启时，在BIOS启动过程中，CPU向带外控制器发送获取请求，以请求目标配置项所配置的内容，之后，CPU基于带外控制器返回的待配置内容，将BIOS芯片中的目标配置项的配置内容修改为待配置内容。这样，BIOS就可以基于BIOS芯片中的目标配置项所配置的待配置内容，为服务器进行配置设置，从而使得服务器重启后，可以自动恢复到重启之前的配置，不必再重新进行配置。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，其中A,B可以是单数或者复数。

另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。同时，在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
首先，对本申请实施例的应用场景进行示例性介绍。
基本输入输出***BIOS是固化在主板上的BIOS芯片中的程序，主要功能是为服务器提供硬件设置和控制。此外，BIOS还向用户提供了多种配置项，通过修改这些配置项的配置内容，可以控制服务器的运行状态。由于BIOS出厂时都是默认配置，而服务器所处不同场景时，对能效调优的需求不一致，通过修改BIOS配置项的内容，可以服务器的运行与当前场景匹配。
相关技术中，服务器的操作***OS运行后，如果想要修改BIOS配置项的配置内容，需要重启操作***，从而在BIOS运行过程中修改BIOS配置项的配置内容。之后，再次操作***，由BIOS执行修改操作，以使BIOS配置项的修改生效。
也就是说，OS运行后，若想要修改BIOS配置项的配置内容，需要重启两次操作***才能使BIOS配置项的修改生效。这样，势必会造成业务中断，严重影响了服务器的正常运行。
有鉴于此，本申请实施例提供了一种基本输入输出***BIOS配置项的配置方法，带外控制器在确定目标配置的待配置内容后，若CPU运行OS，则向CPU发送***管理中断信号，实现指示CPU由运行OS转换为运行BIOS，并在CPU运行BIOS的过程中，将目标配置项的内容配置为待配置内容，从而实现修改目标配置项的配置内容。由于***管理中断信号还能够指示CPU在BIOS完成目标配置项的配置后，恢复运行OS，因此，能够在不重启***的情况下修改目标配置项，从而实现了在保持服务器的业务连续在线的情况下修改目标配置项。
其次，对本申请实施例的***架构进行示例性介绍。
如图1所示，为本申请实施例提供的一种服务器的***架构图。
硬件方面，服务器包括中央处理器(central processing unit，CPU)、***管理内存(system management random access memory，SMRAM)和带外控制器。
软件方面，该服务器包括BIOS和OS。其中，OS和BIOS由CPU运行。
OS，包括操作***程序代码。操作***可以是Linux、Windows或vxWarks等。
在本申请实施例中，OS主要用于运行业务，以及能耗管理。
BIOS，是加载在服务器硬件***上的最基本的软件代码，用于上电、自检、CPU初始化、内存初始化、检测输入输出设备以及可启动设备，并最终引导OS启动。也就是说，服务器上电后，首先是启动BIOS，之后，由BIOS引导OS启动。
其中，BIOS的启动过程主要包括以下7个阶段：
验证阶段(security，SEC)、EFI环境预初始化阶段(pre-efi initialization environment，PEI)、驱动运行环境阶段(driver execution environment，DXE)、引导设备选择阶段(boot device select，BDS)、临时***运行阶段(transient system load，TSL)、运行时阶段(runtime，RT)、后世阶段(after life，AL)。
在本申请实施例提供的方法中，BIOS主要用于向带外控制器上报支持在线修改的配置项的信息，以及将支持在线修改的目标配置项的内容配置为待配置内容。
***管理内存，用于存储CPU进入***管理模式前的CPU上下文，以及CPU进入SMM模式后所要运行的程序(如***管理中断指示的SMM处理程序)。
带外控制器，可以通过专用的数据通道对服务器进行远程维护和管理。带外控制器完全独立于服务器的CPU、BIOS以及OS之外，可以通过服务器的带外管理接口与运行在CPU中的BIOS和OS(或OS管理单元)进行通信。
在本申请实施例提供的方法中，带外控制器主要用于向终端设备发送界面配置信息、目标配置项的标识，向BIOS下发目标配置项的待配置内容，以及存储目标配置项的配置结果。
示例性的，带外控制器可以包括服务器外部的监控管理单元、处理器外的管理芯片中的管理***、服务器的基板管理控制器(baseboard management controller，BMC)、***管理模式(system management mode，SMM)模块等。需要说明的，本申请实施例对带外控制器的具体形式并不限定，以上仅为示例性说明。在下述实施例中，仅以带外控制器为BMC为例进行说明。
需要说明的，不同服务器对BMC有不同的称呼，例如，一些服务器称为BMC，一些服务器称为iLO，另一服务器称为iDRAC。不论是叫BMC，还是叫iLO或iDRAC，都可以理解为是本发明实施例中的BMC。
在一些实施例中，该服务器还包括南桥(platform controller hub，PCH)、复杂可编程逻辑器件(complex  programmable logic device，CPLD)。其中，带外控制器与CPLD连接，CPLD与PCH连接。关于PCH和CPLD的具体用途将在后续实施例中进行说明，此处不再细述。
如图2所示，为本申请实施例提供的一种BIOS配置项的配置***，该***包括终端设备和服务器(参见图1)，终端设备和服务器通过网络连接，或者，也可以通过通信总线进行连接。其中，终端设备用于生成BIOS配置中的目标配置项的待配置内容，并将目标配置项的待配置内容发给服务器。服务器用于基于接收目标配置项的待配置内容，并将目标配置项的内容配置为待配置内容。
在一些实施例中，终端设备可以被称为：终端、用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置等。终端设备可以是手机、增强现实(augmented reality，AR)设备、虚拟现实(virtual reality，VR)设备、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等。
以下，对本申请涉及的术语进行简要介绍。
***管理中断(system management interrupt，SMI)：是服务器中的最高优先级的中断，无法被屏蔽。***管理中断被触发后，CPU进入***管理模式(system management mode，SMM)，并执行***管理中断所指示的中断处理程序。
其中，***管理中断分为软件中断和硬件中断，软件中断是指使用程序设定产生中断，硬件中断是指使用外部硬件产生中断。
***管理模式：是英特尔(Intel)x86体系结构的一种CPU执行模式。目前，***管理模式只能通过***管理中断进入。在***管理模式下，其他经过CPU的操作都被屏蔽。此时，操作OS处于一种“被冻住”的状态，其他所有中断都无法处理。

需要说明的，本申请实施例描述的***架构以及应用场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着***架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
为了便于理解，以下结合附图对本申请提供的基本输入输出***BIOS配置项的配置方法进行示例性介绍，该方法适用于图1至图2所示的***架构。
本申请以下实施例将分成三部分对基本输入输出***BIOS配置项的配置方法进行介绍。
第一部分，结合图3介绍CPU向带外控制器上报BIOS配置项中支持在线修改的配置项的过程。
第二部分，结合图4至图5介绍一种带外控制器对第一部分中支持在线修改的配置项进行配置的过程。
第三部分，结合图6介绍另一种带外控制器对第一部分中支持在线修改的配置项进行配置的过程。
图3是根据一示例性实施例示出的一种基本输入输出***BIOS配置项的配置方法的流程图。示例性的，该方法包括以下S301-S304。
需要说明的，S301-S304中的CPU执行某个步骤(如S301、S302以及S304)，可以认为是CPU调用BIOS执行该步骤。
S301：CPU向带外控制器发送配置项集合。
其中，配置项集合为当前版本的BIOS支持在线修改的配置项的集合。配置项集合包括支持在线修改的多个配置项，多个配置项包括目标配置项。示例性的，配置项集合可以包括支持多个配置项标识，多个配置项标识用于指示支持在线修改的多个配置项。其中，配置项标识与配置一一对应，也即，一个配置项标识指示一个配置项。
BIOS对支持在线的配置项执行修改操作后，不需要重启***，该支持在线的配置项的修改后的配置内容就能够生效。其中，在线是指OS在线，生效是指服务器可以基于该修改后的配置内容运行。例如，支持在线修改的配置项包括节能模式，在节能模式由“开启”修改为“关闭”后，无需重启***，服务器就能够以关闭节能模式的高性能模式运行。
也就是说，支持在线修改的配置项的配置内容被修改后，例如，支持在线修改的配置项a(以下简称配置项a)所配置的内容1被修改为内容2，无需重启***，该配置项a所配置的内容2即生效，也即，服务器可以基于配置项a所配置的内容2运行。
在一些实施例中，支持在线修改的配置项的配置内容存储寄存器中。其中，一个支持在线修改的配置项对应一个寄存器。支持在线修改的配置项与寄存器一一对应，也即，一个寄存器中仅存储一个支持在线修改的配置项的配置内容所对应的数据，示例性的，目标配置项所对应的寄存器为目标寄存器，目标寄存器中仅存储目标配置项的配置内容所对应的数值。
示例性的，该多个配置项包括配置项a，配置项a可以是多个配置项中的任意一个配置项。以下，以配置项a为例，对支持在线修改的配置项所具有的特性进行示例性说明。
在一些实施例中，配置项a的原配置内容所对应的数值a存储于寄存器a中，若要修改配置项a的配置内容，只需修改寄存器a中的数值即可。基于此，若要将配置项a的原配置内容修改为新配置内容，只需将寄存器a中的原数值a修改为新配置内容所对应的数值b。在寄存器a中的内容被修改为数值b后，无需重启***，服务器即可基于寄存器a的数值b所对应的新配置内容运行。
可选地，配置项集合包括动态节能、非核心功率缩放、硬件预读取、数据缓存单元预读取、三级缓存预读取、电源性能调整、电源的能效偏好模式等配置项。
其中，动态节能的可配置内容包括节能模式开启和节能模式关闭。在节能模式开启状态下，可配置内容还包括多个不同的节能等级，如，0级、1级、2级、……、M级等。
非核心功率缩放的可配置内容包括开启和关闭，在开启下状态下，可配置内容还包括多个百分比，如，10％、30％、60％等。
硬件预读取的可配置内容包括开启和关闭。数据缓存单元预读取的可配置内容包括开启和关闭。三级缓存预读取的可配置内容包括开启和关闭。
电源性能调整的可配置内容包括BIOS和OS。若选择BIOS，则表示由BIOS控制电源性能调整的策略选择，若选择OS，则表示由OS控制电源性能调整的策略选择。
能效偏好模式的可配置内容包括性能均衡模式、性能优先模式、功耗均衡模式和节能优先模式。其中，能效偏好模式属于电源性能的策略，也就是说，若电源性能调整配置为OS，则由OS控制能效偏好模式的配置。
可选地，BIOS的程序中预先配置有支持在线修改的多个配置项。CPU中运行的BIOS可以基于程序中配置的支持在线修改的多个配置项，确定向带外控制器发送的配置项集合。
需要说明的，不同版本的BIOS的配置项集合的内容可以不同，或者，也可以相同，本申请实施例对此不做限制。
在一些实施例中，服务器上电后，在BIOS启动阶段，CPU中运行的BIOS主动向带外控制器发送当前版本的BIOS支持在线修改的配置项的集合。示例性的，BIOS可以在驱动运行环境阶段(driver execution environment，DXE)发送当前版本的BIOS支持在线修改的配置项的集合。
在另一些实施例中，OS启动后，带外控制器触发目标***管理中断信号，该目标***管理中断信号用于指示CPU由运行OS转换为运行BIOS，并向带外控制器发送当前版本的BIOS支持在线修改的配置项的集合。
示例性的，CPU接收到目标***管理中断信号后，进入SMM模式，实现由运行OS转换为运行BIOS。之后，CPU运行的BIOS向带外控制器发送支持在线修改的配置项的集合。在CPU运行的BIOS向带外控制器发送支持在线修改的配置项的集合后，CPU退出SMM模式，恢复运行OS。
在一个示例性中，CPU运行的BIOS基于支持在线修改的配置项生成JSON文件1，该JSON文件1包括配置项集合中的每个配置项的标识，也即，支持在线修改的配置项的标识。CPU运行的BIOS向带外控制器发送IPMI命令1，该IPMI命令1携带JSON文件1，从而实现将支持在线修改的配置项的集合发送给带外控制器。
在另一个示例中，CPU运行的BIOS向带外控制器发送IPMI命令2，IPMI命令2携带有配置项集合的信息，从而实现将支持在线修改的配置项的集合发送给带外控制器。
在一些实施例中，CPU运行的BIOS还向带外控制器发送BIOS配置项、BIOS配置的可配置内容，以及BIOS配置项的当前配置内容。
需要说明的，关于该部分内容将在后续实施例中进行说明，此处不再细述。
S302：CPU判断是否发送成功。
若判断结果为是，则执行S303。若判断结果为否，则执行S304。
在一些实施例中，CPU运行的BIOS向带外控制器发送配置项集合后，若在预设时长内未收到带外控制器的回复，则确定为发送失败，若在预设时长内收到带外控制器的回复，则确定发送成功。其中，预设时长可以是0.5秒、1秒、1.5秒等，需要说明的，本申请实施例对预设时长的具体数值不做限制。
在另一些实施例中，CPU运行的BIOS向带外控制器发送配置项集合后，若在预设时长内未收到带外控制器的回复，则再次向带外控制器发送配置项集合。再发送N次后，若仍未在预设时长内容收到带外控制器的回复，则确定发送失败。N为大于1的正整数。通过设置发送N次后，再判断是否发送成功，相较于发送1次就判断是否发送成功，有助于提高发送成功的概率。
需要说明的，本申请实施例对N的具体数值不做限制，例如，N可以是5、6等数值。
S303：带外控制器接收CPU发送的配置项集合。
在一些实施例中，带外控制器在接收到IPMI命令1，通过解析JSON文件1确定BIOS配置项中支持在线修改的配置项。
在另一些实施例中，带外控制器在接收到IPMI命令2，解析IPMI命令2确定BIOS配置项中支持在线修改的配置项。
在一些实施例中，带外控制器接收到配置项集合后，将配置项集合存储在本地缓存中，以便后续服务器运行OS过程中，对BIOS配置项中在支持在线修改的配置项进行修改。可选地，配置项集合还包括BIOS版本号。
在一些实施例中，带外控制器在接收到配置项集合后，基于配置项集合所包括的BIOS版本号与带外 控制器中存储的历史配置项集合所包括的BIOS版本号进行比对，判断BIOS版本是否发生改变，若BIOS版本发生改变，则带外控制器存储该新接收到的配置项集合，该新接收到的配置项集合用于确定下述实施例中的目标配置项。若BIOS版本未发生改变，带外控制区可以存储该新接收到的配置集合，或者，也可以不存储该信息接收到的配置项集合。
S304：CPU打印异常信息。
在一些实施例中，CPU运行的BIOS向带外控制器发送配置项集合失败，CPU运行的BIOS打印异常信息，以记录本次未向带外控制器发送配置项集合失败。在打印异常信息后，BIOS继续运行。
上述实施例中，CPU运行的BIOS通过向带外控制器发送配置项集合，一方面，能够使得带外控制器可以基于该配置项集合，确定BIOS配置项中的哪些配置项支持在线修改。另一方面，由于配置项集合为当前版本的BIOS支持在线修改的配置项的集合，因此，有助于提高所确定的目标配置项与当前版本的BIOS相匹配。
图4是根据一示例性实施例示出的一种基本输入输出***BIOS配置项的配置方法的流程图。示例性的，该方法包括以下S401-S410。
S401：带外控制器向终端设备发送界面配置信息。
其中，界面配置信息用于终端设备显示配置界面，配置界面包括目标配置项。目标配置项为BIOS配置项中支持在线修改的配置项。
可选地，目标配置项包括配置项集合中的一个或多个配置项。
其中，目标配置项可以包括配置项集合中的部分配置项，或者，也可以包括配置项集合中的全部配置项，本申请实施例对此不做限制。
在一些实施例中，服务器上电后，BIOS启动过程中，CPU运行的BIOS向带外控制器发送配置项集合，带外控制器基于配置项集合中的目标配置项的标识，在BIOS启动过程中，生成界面配置信息。
在另一些实施例中，服务器的OS运行后，带外控制器基于本地缓存中存储的配置项集合中的目标配置项的标识，在OS运行阶段，生成界面配置信息。在一些实施例中，带外控制器生成第一界面配置信息，该第一界面配置信息所对应的第一配置界面可以显示配置项集合中的部分配置项。该部分配置项为带外控制器确定的当前需要修改的配置项。例如，可以是基于服务器的当前运行场景确定的，或者，还可以是基于服务器的当前运行业务确定，本申请实施例对此不做限制。
在另一些实施例中，带外控制器生成第二界面配置信息，该第二界面配置信息所对应的第二配置界面可以显示配置项集合中的全部配置项。
需要说明的，带外控制器可以在CPU运行BIOS时，向终端设备发送界面配置信息，或者，也可以在CPU运行OS时，向终端设备发送界面配置信息，本申请实施例对此不做限制。
S402：终端设备显示配置界面，并响应于对配置界面上的目标配置项的配置操作，确定目标配置项的待配置内容。
可选地，配置界面包括Web界面。通过设置配置界面包括Web界面，可以在浏览器上显示该配置界面，相对于使用专用应用程序显示配置界面，有助于简化配置界面的显示过程。
在一些实施例中，如图5所示，为配置界面的示意图。在用户对配置界面上的目标配置项(如动态节能配置项)执行配置操作时，例如，用户将目标配置项的内容配置为关闭节能模式(即待配置内容)，终端设备响应于该配置操作，确定目标配置项的待配置内容。
可以理解的，待配置内容可以是关闭或开启等状态选项，或者，也可以数值，例如，目标配置项为非核心功率缩放时，若非核心功率缩放处于开启状态，则待配置内容还包括具体的缩放百分比，如，30％。因此，本申请实施例对待配置内容的形式不做限制。
需要说明的，可以在CPU运行BIOS时，就允许用户对目标配置项进行配置，或者，也可以在CPU 运行OS时，才运行对目标配置项进行修改。需要说明的，本申请实施例对终端设备修改目标配置项的时机不做限制。
S403：终端设备向带外控制器发送目标配置项的待配置内容。
在一些实施例中，终端设备确定目标配置项的待配置内容后，向带外控制器发送目标配置项的待配置内容。例如，可以是终端设备生成JSON文件2，该JSON文件2记载了目标配置项的待配置内容，终端设备通过将JSON文件2发送给带外控制器，实现将目标配置项的待配置内容发送给带外控制器。
S404：带外控制器确定BIOS配置项中目标配置项的待配置内容。
在一些实施例中，带外控制器接收终端设备发送的目标配置项的待配置内容后，即执行S404，也即，确定目标配置项的待配置内容。示例性的，带外控制器接收到JSON文件2，通过解析JSON文件2得到待配置内容。
在另一些实施例中，带外控制器接收到终端设备发送的待配置内容后，在确定CPU运行OS的情况下，执行S404，也即，确定BIOS配置项中目标配置项的待配置内容。
在一些实施例中，带外控制器确定BIOS配置项中目标配置项的待配置内容，可以是带外控制器根据待配置内容生成JSON文件3，该JSON文件3包括目标配置项以及目标配置项的待配置内容。
在一些实施例中，带外控制器预先存储有目标配置项的可配置内容，在接收到目标配置项的待配置内容后，确定待配置内容是否属于可配置内容，若判断结果为是，则执行S405，否则，结束。
在另一些实施例中，带外控制器预先存储有目标配置项的当前配置内容，在接收到目标配置项的待配置内容后，确定待配置内容与当前配置内容是否相同，若判断结果为是，则结束，若判断结果为否，则执行S405。
需要说明的，目标配置项的可配置内容，以及目标配置项的当前配置内容，由BIOS发送给带外控制器，带外控制器存储在本地缓存中。
S405：若CPU运行操作***OS，带外控制器向CPU发送***管理中断信号。
***管理中断信号用于指示CPU执行目标操作。目标操作包括以下S407-S410。
在一些实施例中，若带外控制器在未确定CPU是否运行OS的情况下，执行的S404，则带外控制器在确定CPU运行OS后，向CPU发送***管理中断信号。示例性的，BIOS向带外控制器发送IPMI命令3，该IPMI命令3包括通知信息，该通知信息用于指示CPU运行OS，带外控制器在接收到BIOS发送的通知信息，确定CPU运行OS。之后，带外控制器向CPU发送***管理中断信号。
在另一些实施例中，若带外控制器在确定CPU运行OS的情况下，执行的S404，则带外控制器在确定目标配置项的待配置内容后，即向CPU发送***管理中断信号。
以下，对带外控制器向CPU发送***管理中断信号的过程进行示例性介绍。
带外控制器拉低通用输入输出(general-purpose input/output，GPIO)，触发***管理中断信号。示例性的，带外控制器配置有寄存器b，带外控制器向寄存器中写入数值c，数值c用于指示拉低GPIO。CPLD在检测到寄存器b写入数值c后，执行数值c所对应的拉低GPIO的操作。PCH在检测到GPIO被拉低后，确定被拉低的GPIO的标识，并基于该标识向CPU发送具有目标标识的***管理中断信号。

S406：CPU接收***管理中断信号，并响应于***管理中断信号执行以下操作。
在一些实施例中，不同的***管理中断信号具有不同的标识，每个标识指示一个***管理中断程序，该一个***管理中断程序指示了CPU进入***管理模式后所需执行的操作。在本申请实施例中，***管理中断信号的目标标识对应目标***管理中断程序，目标***管理中断程序指示了S408-S410中的操作。
S407：CPU由运行OS转换为运行BIOS。
可选地，***管理中断信号还用于指示CPU进入***管理模式。

在另一些实施例中，若目标配置的配置内容存储静态文件中，CPU中运行的BIOS将待配置内容写入该静态文件中，从而实现将目标配置的内容配置为待配置内容。
需要说明的，待配置内容写入静态文件后，目标配置项的配置内容即生效，之后，服务器便基于目标配置项的待配置内容所指示的模式运行。
S410：若CPU完成目标配置项的配置，CPU恢复运行OS。

S412：带外控制器接收CPU发送的目标配置项的配置结果。
在一些实施例中，带外控制器接收到目标配置项的配置结果后，若配置结果指示配置成功，则生成目标文件(JSON文件4)，目标文件包括目标配置项和待配置内容。该目标文件用于记录支持在线修改的配置项中，已修改的目标配置项以及目标配置项当前所配置的内容。
在服务器的整个运行阶段，若带外控制器对目标配置项进行了多次修改，在一些实施例中，带外控制器仅保存最新生成的目标文件。在另一些实施例中，带外控制器保存每次修改目标配置项后生成的目标文件，基于此，在CPU中运行的BIOS请求获取目标配置项所配置的内容时，带外控制器基于最新生成目标文件，向CPU运行的BIOS返回目标配置项当前所配置的内容。
