附图说明
为了更清楚地说明本申请实施例中的技术方案,下面将对现有技术和实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。
图1为本申请实施例提供的一种服务器BIOS启动进程的监测方法的流程图;

图3为本申请实施例提供的一种服务器BIOS启动进程的监测装置的具体结构示意图;
图4为本申请实施例提供的一种eSPI协议的原理图;
图5为本申请实施例提供的一种服务器BIOS启动进程的监测系统的结构示意图。
具体实施方式
本申请的核心是提供一种服务器BIOS启动进程的监测方法、系统及装置,用户可直接通过显示的信息快速确定出BIOS当前的启动进程,从而利于服务器在BIOS启动过程中问题的快速定位。
为使本申请实施例的目的、技术方案和优点更加清楚,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清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
请参照图1及图2,图1为本申请实施例提供的一种服务器BIOS启动进程的监测方法的流程图;图2为本申请实施例提供的一种服务器BIOS启动进程的监测装置的结构示意图。
该服务器BIOS启动进程的监测方法应用于处理器,包括:
步骤S1:检测服务器内的PCH是否开始向BMC传输数据;若PCH开始向BMC传输数据,则执行步骤S2。
步骤S2:从PCH和BMC之间的IO传输线上获取数据并解析,且判断解析后的数据中是否包含表示服务器的BIOS启动进程的进程数据;若解析后的数据中包含表示服务器的BIOS启动进程的进程数据,则执行步骤S3。
步骤S3:将进程数据进行显示。
具体地,考虑到在服务器中的BIOS启动过程中,服务器的PCH会通过与BMC之间连接的IO(Input/Output,输入/输出)传输线,向BMC传输BIOS启动进程等信息,所以本申请检测服务器内的PCH是否开始向BMC传输数据,若PCH未开始向BMC传输数据,则继续检测的PCH是否开始向BMC传输数据;若PCH开始向BMC传输数据,则从PCH和BMC之间的IO传输 线上获取数据,并对从IO传输线上获取的数据进行解析,然后判断解析后的数据中是否包含表示服务器的BIOS启动进程的进程数据,若解析后的数据中不包含表示服务器的BIOS启动进程的进程数据,则对本次传输的数据不做处理;若解析后的数据中包含表示服务器的BIOS启动进程的进程数据,则将表示服务器的BIOS启动进程的进程数据进行显示,如将进程数据通过多个LED(light-emitting diode,发光二极管)进行显示,便于用户直接通过显示的信息快速确定出BIOS当前的启动进程。
本申请提供了一种服务器BIOS启动进程的监测方法,应用于处理器,包括:检测服务器内的PCH是否开始向BMC传输数据;若PCH开始向BMC传输数据,则从PCH和BMC之间的IO传输线上获取数据并解析,且判断解析后的数据中是否包含表示服务器的BIOS启动进程的进程数据;若解析后的数据中包含进程数据,则将进程数据进行显示。可见,用户可直接通过显示的信息快速确定出BIOS当前的启动进程,从而利于服务器在BIOS启动过程中问题的快速定位。
在上述实施例的基础上:
请参照图3,图3为本申请实施例提供的一种服务器BIOS启动进程的监测装置的具体结构示意图。
作为一种可选的实施例,PCH和BMC之间的连接线包括时钟信号线、eSPI_IO传输线及CS信号线;
则检测服务器内的PCH是否开始向BMC传输数据,包括:
检测时钟信号线上的时钟信号和CS信号线上的CS信号,并判断时钟信号是否为低电平、CS信号是否出现下降沿;
若判断结果为时钟信号为低电平且CS信号出现下降沿,则确定PCH开始向BMC传输数据;
若判断结果为时钟信号不为低电平和/或CS信号未出现下降沿,则确定PCH未开始向BMC传输数据。
具体地,本申请的服务器内PCH支持eSPI(Enhanced Serial Peripheral Interface,增强型串行设备接口)总线,eSPI总线是一种点对点的通信方式, 用于PCH与BMC之间大量的数据通信。处理器作为第三方设备,可通过监控的方式实现PCH与BMC之间传输数据的解析。
如图3所示,服务器内PCH和BMC之间的连接线包括时钟信号线(CLK)、eSPI_IO传输线及CS(chip select,片选)信号线,还可包括Alert(提醒)信号线和reset(重置)信号线;处理器只需要用到时钟信号线、eSPI_IO传输线及CS信号线,处理器分别与时钟信号线、eSPI_IO传输线及CS信号线连接,以接收来自PCH的CLK/CS/IO硬件信号;其中,处理器仅作为一个监控设备接收eSPI总线的数据,因此原本双向的IO,对于处理器来说是单向输入的。
考虑到当CLK信号为低电平、CS信号出现下降沿时,PCH开始向BMC传输数据,所以本申请检测时钟信号线上的CLK信号和CS信号线上的CS信号,并判断CLK信号是否为低电平、CS信号是否出现下降沿;若CLK信号为低电平、CS信号出现下降沿,即判断结果均为是,则确定PCH开始向BMC传输数据,以从eSPI_IO传输线上获取二者传输的数据;反之,若CLK信号不为低电平和/或CS信号未出现下降沿,即判断结果不均为是,则确定PCH未开始向BMC传输数据。
作为一种可选的实施例,PCH向BMC传输的数据依次包括CMD信息、HDR信息及DATA信息;
则从PCH和BMC之间的IO传输线上获取数据并解析,且判断解析后的数据中是否包含表示服务器的BIOS启动进程的进程数据,包括:
从eSPI_IO传输线上获取CMD信息并解析,且判断解析后的CMD信息是否对应写数据模式;
若解析后的CMD信息对应写数据模式,则从eSPI_IO传输线上继续获取HDR信息并解析,且判断解析后的HDR信息是否为BIOS启动进程代码的地址;
若解析后的HDR信息为BIOS启动进程代码的地址,则从eSPI_IO传输线上继续获取DATA信息并解析,得到表示服务器的BIOS启动进程的进程数据,以进入将进程数据进行显示的步骤。
具体地,请参照图4,图4为本申请实施例提供的一种eSPI协议的原理图。主机端通过发送COMMAND(命令)给到从机端,实现写数据的操作;而从机端通过RESPONSE(响应)反馈数据,实现读数据的操作。
在PCH和BMC的数据交互过程中,PCH会发送BIOS启动进程代码给到BMC(PCH为主机,BMC为从机),基本流程如下:
1)PCH设置CMD(command,命令提示符)信息为PUT_IOWR_SHORT模式(写数据模式),则配置总线为写数据模式,此模式下,由PCH向BMC写数据。
2)PCH通过HDR(High Data Register,高速数据寄存器)信息向BMC发送16bit(比特位)地址,以通知BMC即将发送的DATA(数据)信息的寄存器地址;其中,BIOS启动进程代码的地址为0080h。
3)PCH向BMC发送BIOS启动进程代码(DATA信息),用于表示BIOS当前的启动进程。
基于此,本申请在检测到PCH开始向BMC传输数据时,从二者之间的eSPI_IO传输线上获取CMD信息并解析,然后判断解析后的CMD信息是否对应写数据模式;若解析后的CMD信息不对应写数据模式,则终止本次的数据监控;若解析后的CMD信息对应写数据模式,则从eSPI_IO传输线上继续获取HDR信息并解析,然后判断解析后的HDR信息是否为BIOS启动进程代码的地址;若解析后的HDR信息不为BIOS启动进程代码的地址,则终止本次的数据监控;若解析后的HDR信息为BIOS启动进程代码的地址,则从eSPI_IO传输线上继续获取DATA信息并解析,解析后的DATA信息便是表示服务器的BIOS启动进程的进程数据,然后进入将进程数据进行显示的步骤。
作为一种可选的实施例,从eSPI_IO传输线上获取目标信息,包括:
从eSPI_IO传输线上获取目标信息开始,每检测到时钟信号的下降沿时,从eSPI_IO传输线上获取一比特位的数据,当连续获取的比特位的总数等于目标信息的比特位总数时,将连续获取的比特位组合得到目标信息;
其中,目标信息为PCH向BMC传输的数据中包含的任一信息。
具体地,在PCH向BMC传输数据开始,依次传输8bit的CMD信息、16bit的HDR信息、8bit的DATA信息。
基于此,本申请在PCH向BMC传输数据开始,每检测到时钟信号的下降沿时,从二者之间的eSPI_IO传输线上获取一比特位的数据,当本次连续获取的比特位的总数等于8bit时,将本次连续获取的比特位组合得到CMD信息。在PCH向BMC传输CMD信息结束后,每检测到时钟信号的下降沿时,从二者之间的eSPI_IO传输线上获取一比特位的数据,当本次连续获取的比特位的总数等于16bit时,将本次连续获取的比特位组合得到HDR信息。在PCH向BMC传输HDR信息结束后,每检测到时钟信号的下降沿时,从二者之间的eSPI_IO传输线上获取一比特位的数据,当本次连续获取的比特位的总数等于8bit时,将本次连续获取的比特位组合得到DATA信息。
作为一种可选的实施例,CMD信息为8bit有效数据,当CMD信息为0100_0100时,CMD信息对应写数据模式;HDR信息为16bit有效数据,BIOS启动进程代码的地址为0080h;DATA信息为8bit有效数据。
具体地,本申请从PCH和BMC之间的eSPI_IO传输线上获取数据并解析的过程具体为:
1)实时监控CLK信号和CS信号,当CLK信号为低电平、CS信号出现下降沿时,PCH开始向BMC传输数据。
2)检测到PCH开始向BMC传输数据后,在CLK信号下降沿时解析IO数据,其中,CMD信息为8bit的有效数据,当解析到CMD信息为0100_0100时,确定解析后的CMD信息对应写数据模式,继续执行下一步;否则终止本次的数据监控。
3)在CLK信号下降沿继续监控IO数据,此时PCH会发送16bit的HDR信息,当解析到HDR信息为0080h时,继续执行下一步;否则终止本次的数据监控。
4)在CLK信号下降沿继续监控IO数据,此时PCH会发送8bit的DATA信息,该8bit数据即为表示服务器的BIOS启动进程的进程数据。
作为一种可选的实施例,PCH向BMC传输的数据还包括CRC信息;
则在得到表示服务器的BIOS启动进程的进程数据之后,在将进程数据进行显示之前,服务器BIOS启动进程的监测方法还包括:
从eSPI_IO传输线上继续获取CRC信息并解析,且根据解析后的CRC信息对进程数据进行校验;
若校验通过,则进入将进程数据进行显示的步骤;
若校验不通过,则不进入将进程数据进行显示的步骤。
进一步地,如图4所示,本申请的PCH向BMC传输的数据还包括CRC(Cyclic Redundancy Check,循环冗余校验)信息。则本申请在得到表示服务器的BIOS启动进程的进程数据之后,从eSPI_IO传输线上继续获取CRC信息并解析,然后根据解析后的CRC信息对得到的进程数据进行校验;若校验通过,说明该次监控获取的进程数据有效,则进入将进程数据进行显示的步骤;若校验不通过,说明该次监控获取的进程数据无效,则不进入将进程数据进行显示的步骤,直接丢弃该次监控获取的进程数据。
另外,BMC在接收到PCH发送的上述数据后,在保证校验结果准确后,会向PCH反馈接收结果,用于通知PCH本次传输数据已接收。若PCH在预设时间内未接收到BMC反馈的接收结果,则认为BMC未接收到本次传输数据,会进行数据重发,以保证BMC接收到所传输的数据。
需要说明的是,上述实施例的步骤均由处理器实现,处理器可选用服务器内的CPLD(Complex Programmable logic device,复杂可编程逻辑器件)。
请参照图5,图5为本申请实施例提供的一种服务器BIOS启动进程的监测系统的结构示意图。
该服务器BIOS启动进程的监测系统包括:

作为一种可选的实施例,PCH和BMC之间的连接线包括时钟信号线、eSPI_IO传输线及CS信号线;
则检测模块1具体用于:
检测时钟信号线上的时钟信号和CS信号线上的CS信号,并判断时钟信号是否为低电平、CS信号是否出现下降沿;
若判断结果为时钟信号为低电平、CS信号出现下降沿,即均为是,则确定PCH开始向BMC传输数据,并执行判断模块;
若判断结果为时钟信号不为低电平和/或CS信号未出现下降沿,即不均为是,则确定PCH未开始向BMC传输数据,不执行判断模块。
