Description
Technical Field
The invention relates to the field of BIOS, in particular to a method, a system, equipment and a storage medium for modifying a maximum effective load value.
Background
The Max Payload Size parameter for PCIe determines the maximum Payload that a TLP may use. For the IIO PCIe ROOT PORT, there is an option at BIOS setup page to set its Max Payload Size: "PCI-E Port Max Payload Size", optional settings are: 128B, 256B, 512B and Auto. Auto refers to the maximum value that the device can support. Different clients may have different requirements for the parameter, such as the A client requiring that MaxPayload Size be set to 256B by default, and for ports supporting hot plug, be set to 256B by default; while the B client requires Max Payload Size to be set to Auto by default and 128B for ports supporting hot-plugging.
The existing scheme is to provide two different sets of codes for two clients, wherein the default setting of the code of the client A is 256B, and the setting is kept unchanged when the hot plug function of PCIe is opened; the "PCI-E Port Max Payload Size" in the B client's code is set to Auto by default, and is modified to 128B when the PCIe hot-plug function is on. However, when the existing scheme is used for customizing the BIOS for different clients, the default setting of the PCI-E Port Max Payload Size must be modified, and the code modification is also needed to judge whether the hot plug function of the PCIe is opened or not, and then different BIOS files are generated by recompilation and provided for different clients. That is, the existing scheme cannot be automatically adapted, multiple sets of codes must be used, and the scheme cannot be suitable for a set of BIOS codes to be compatible with all items corresponding to different users.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
It should be noted that, in the embodiment of the present invention, the PCI-E Port Max Payload Size is a maximum Payload value that may be used by a TLP, a TLP (transaction Layer packet) transaction Layer packet, and a bios (basic Input Output system) basic Input Output system.
According to an aspect of the present invention, an embodiment of the present invention provides a method for modifying a maximum payload value, as shown in fig. 1, including performing the following steps based on a BIOS: s1, initializing in response to receiving the starting instruction; s2, acquiring the value of GPIO of the mainboard; s3, determining the maximum effective load value to be acquired according to the GPIO value; s4, judging whether hot plug is supported; s5, responding to the support of hot plug, and acquiring the maximum effective load value corresponding to the support of hot plug based on the maximum effective load value to be acquired; and S6, updating the corresponding variable by using the maximum effective load value corresponding to the hot plug supporting time.
The scheme provided by the invention can automatically and dynamically change the setting of PCIe Max Payload Size according to the project without manually modifying option default values and codes and recompiling, simultaneously enables a set of BIOS codes to be compatible with all projects, does not need to develop multiple sets of codes according to different projects, improves the code quality, saves the time of BIOS engineers and improves the working efficiency.
In some embodiments, in step S2, obtaining the value of the GPIO of the motherboard further includes:
judging whether the starting is the first starting according to a preset parameter corresponding to the starting times;
and acquiring the value of the GPIO in response to the first starting.
Specifically, after the BIOS is started, it may be determined that the BIOS is started for the second time according to the variable parameter, and when the BIOS is determined to be started for the first time according to the variable parameter, the maximum payload value needs to be modified, that is, the corresponding modification step needs to be performed, and at this time, the value of the GPIO is obtained.
In some embodiments, the variable parameter may be determined to be a first boot by determining whether the variable parameter exists after the BIOS is booted, i.e., the variable parameter does not exist for the first boot, and the variable parameter does not exist for the second and subsequent boots. Or, whether the starting is the first time is determined by judging the value corresponding to the variable parameter, namely, when the value of the variable parameter is 1, the starting is the first time. When the value of the variable parameter is other values, it is not the first start.
In some embodiments, the method further comprises:
in response to not being the first boot, no subsequent steps are performed.
Specifically, when the variable parameter exists or the value corresponding to the variable parameter is not 1, it is not the first start, and at this time, the step of modifying the maximum Payload value is not performed, that is, the maximum Payload value is modified only when the BIOS is started for the first time, so that it can be ensured that the PCI-E Port Max Payload Size can be successfully modified normally in SETUP.
In some embodiments, in step S3, determining the maximum payload value to be obtained according to the value of the GPIO may further include:
and determining an array consisting of maximum effective load values to be acquired under different conditions according to the value of the GPIO.
Specifically, two variables oempcpdmaxpayloydsize and oempcpdmaxpayloyeff are predefined and respectively used for storing corresponding values of the PCI-E Port Max Payload Size when hot plug is not supported and when hot plug is supported. In some embodiments, the maximum payload value requirements of different users may be grouped into a plurality of arrays by the variables oempccdmaxpaydoadsize and oempccdmaxpaydoadsizeforhp, respectively. Therefore, after the GPIO value of the mainboard is detected, the array to be acquired can be determined. For example, when the GPIO value of the mainboard is detected to judge that the item required by the user A is A, the array to be acquired is determined to be A, the variable OempCaxMaxParadSize in the array A is 256B, and the OempCdMaxParadSizeForHp is 256B; when the GPIO value of the mainboard is detected to judge that the item is the item required by the user B, the array to be acquired is determined to be B, the variable OempCdMaxParaloyAdSize in the array B is Auto, and the OempCdMaxParaloyAdSizeForHp is 128B.
It should be noted that, before obtaining and modifying the maximum payload value, the corresponding array to be obtained needs to be determined first, that is, the array formed by the maximum payload values corresponding to different situations needs to be determined first.
In some embodiments, determining the array to be obtained may be performed early in the PEI phase when the BIOS first boot initialization is flushed.
In some embodiments, after the array to be obtained is determined in the early stage of the PEI phase, the determination in step S4 is performed to determine whether hot plug is supported, and obtain the corresponding maximum payload value.
In some embodiments, the method further comprises:
in response to that hot plug is not supported, acquiring a maximum effective load value corresponding to the time when hot plug is not supported based on the maximum effective load value to be acquired;
and updating the corresponding variable by using the maximum effective load value corresponding to the condition that the hot plug is not supported.
Specifically, in the PEI phase, after the array to be obtained is determined, the corresponding maximum payload value is obtained after the PEI phase determines whether hot plug is supported. Meanwhile, because the variable value of the SETUP in the stage can only be obtained but cannot be modified, when the value of 'PCI-E Port Max Payload Size' in the SETUP is obtained, firstly, the PCIe Port is judged not to start hot plug, if the hot plug is supported, OemPcdMaxPayloadSizeForHp is returned, otherwise, OemPcdMaxPayAdSidSize is returned. Finally, step S6 is performed to update the corresponding variable with the maximum payload value corresponding to the hot plug support.
It should be noted that, the variable corresponding to the maximum payload value obtained is updated in the DXE phase, because the phase can change the value of the SETUP variable, the value of the SETUP variable is updated in the early phase of DXE, and thus, the SETUP variable is updated with oemcpctmaxpayloyadsize or oemcpctmaxpayoadsizefhaphp according to whether hot plug is supported or not.
The scheme provided by the invention can automatically and dynamically change the setting of PCIe Max Payload Size according to the project without manually modifying option default values and codes and recompiling, simultaneously enables a set of BIOS codes to be compatible with all projects, does not need to develop multiple sets of codes according to different projects, improves the code quality, saves the time of BIOS engineers and improves the working efficiency.
