具体实施方式detailed description
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,所描述的实施例仅仅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作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。The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.
在现有技术中,基于Intel x86架构的设计,一个PCIE port最大的链路宽度为x16,其中,一个x16又可以分为2个x8或4个x4,这些配置一般都是BIOS预先分配的,如果配置为x4,则限定了卡link的最大宽度为x4,对后期所接的卡存在一定的限制。In the prior art, based on the Intel x86 architecture design, the maximum link width of a PCIE port is x16. Among them, one x16 can be divided into 2 x8 or 4 x4. These configurations are generally pre-allocated by the BIOS. If the configuration is x4, the maximum width of the card link is limited to x4, and there are certain restrictions on the cards connected later.
因此,本申请实施例公开了一种PCIE宽度自动适配方法,参见图1,本申请实施例公开的一种PCIE宽度自动适配方法的流程图,如图1所示,包括:Therefore, an embodiment of the present application discloses a PCIE width automatic adaptation method. Referring to FIG. 1, a flowchart of a PCIE width automatic adaptation method disclosed in an embodiment of the present application, as shown in FIG. 1, includes:
S101:在PCIE port初始化后,获取预先保存的配置信息;S101: After the PCIE port is initialized, obtain the pre-saved configuration information;
本实施例中,BIOS默认配置为4个x4,在PCIE port初始化后,获取预先保存的用于配置主机端PCIE宽度的配置信息。In this embodiment, the BIOS is configured as 4 x4 by default, and after the PCIE port is initialized, the pre-saved configuration information for configuring the PCIE width of the host side is obtained.
S102:获取与当前外接卡对应的转接卡的标识信息;S102: Obtain identification information of the adapter card corresponding to the current external card;
进一步地,获取当前外接卡对应的转接卡,并确定转接卡的标识信息。Further, the adapter card corresponding to the current external card is acquired, and the identification information of the adapter card is determined.
S103:确定所述配置信息中与所述标识信息对应的宽度信息,并根据所述宽度信息配置主机端PCIE的宽度。S103: Determine the width information corresponding to the identification information in the configuration information, and configure the width of the PCIE on the host side according to the width information.
本步骤中,从配置信息中获取与标识信息对应的宽度信息,从而利用宽度信息实现主机端PCIE宽度的配置。In this step, the width information corresponding to the identification information is obtained from the configuration information, so that the width information is used to implement the configuration of the PCIE width on the host side.
可以理解的是,x16的PCIE链路在走线时默认配置为4个x4,在通过预设转接卡连接到外接卡后,由于转接卡的标识信息不同,通过区分转接卡的宽度,确定是否将两个x4合成一个x8,或将4个x4合成一个x16,来配置主机端PCIE宽度,在配置后,主机端即可以与相应宽度的转接卡进行连接。It is understandable that the x16 PCIE link is configured as 4 x4 by default when routing. After connecting to the external card through the preset riser card, because the identification information of the riser card is different, by distinguishing the width of the riser card , Determine whether to combine two x4s into one x8, or four x4s into one x16 to configure the PCIE width of the host side. After configuration, the host side can be connected with the riser card of the corresponding width.
通过以上方案可知,本申请提供的一种PCIE宽度自动适配方法,包括:在PCIE port初始化后,获取预先保存的配置信息;获取与当前外接卡对应的转接卡的标识信息;确定所述配置信息中与所述标识信息对应的宽度信息,并根据所述宽度信息配置主机端PCIE的宽度。本申请通过预先保存标识信息以及对应的宽度信息,在当前主机端连接到外接卡对应的转接卡后,利用转接卡的标识信息确定对应的宽度信息,从而为主机端PCIE配置相应的宽度,实现PCIE宽度的自动适配。It can be seen from the above solution that the PCIE width automatic adaptation method provided by this application includes: obtaining the pre-saved configuration information after the PCIE port is initialized; obtaining the identification information of the adapter card corresponding to the current external card; determining the Configure the width information corresponding to the identification information in the information, and configure the width of the PCIE at the host side according to the width information.
