Description

Technical Field

[0001] The present application relates to the field of servers, and in particular to a processing method and device based on an external device in a server. Background Art

[0002] There are many PCI (Peripheral Component Interconnect, a local bus standard) devices and PCIe (Peripheral Component Interconnect express, a high-speed serial computer expansion bus standard) devices in the server system. In order to implement certain functions or initialize registers, these external devices generally have a built-in firmware program called PCI option rom (a firmware execution program that comes with a PCI / PCIe external card).

[0003] Currently, the program running modes of the X86 system can be divided into Legacy mode (traditional computer running mode) and UEFI (Unified Extensible Firmware Interface) mode. In Legacy mode, the PCI option rom is referred to as Legacy option rom.

[0004] When software in an X86 system reads and writes PCI / PCIe devices, there are two access methods: access based on the hexadecimal addresses CF8 and CFC in I / O (input and output), and access mapped to the memory address space through ECAM (Enhanced Configuration Access Mechanism). When the Legacy PCI optionrom reads and writes PCI / PCIe devices, due to some restrictions, only the first access method can be used, and the first access method can only support a maximum of 256 BUS (computer system buses), that is, it can only support single SEGMENT (data file space) mode, and cannot support multi-SEGMENT mode.

[0005] In a multi-CPU server platform of the X86 system, there are sometimes more than 256 PCIE devices, and the multi-SEGMENT mode needs to be used. Generally, one CPU is divided into one segment, that is, CPU0 is divided into segment0, and CPU1 is divided into segment1. Therefore, the bus / device / function addresses of the external cards of each CPU will be repeated. Therefore, in Legacy mode, when the BIOS (Basic Input Output System) calls the Legacy PCI option rom on the external card of CPU1, it cannot confirm whether the accessed external card is the external card on CPU0 or CPU1, resulting in an error.

[0041] To make the above - mentioned objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0042] Refer to Figure 1 , which shows a flowchart of steps of an embodiment of a method for processing an external device in a server according to the present application. The method may include the following steps:

[0043] Step 101: When at least two external devices are connected to the server, determine the data space mode configured by the server for the at least two external devices.

[0044] When the BIOS of the server is started, if at least two external devices are already connected to the server, determine the data space mode configured by the server for the at least two external devices.

[0045] In some embodiments of the present application, before determining the data space mode configured by the server for the at least two external devices in step 101, the method may further include the following steps:

[0046] Pre - load the firmware program.

[0047] Since at least two external devices are connected to the server, when the BIOS of the server is started, the firmware programs in the connected external devices are pre - loaded, so that there is no need to reload when it is determined that the firmware program needs to be run.

[0048] In some embodiments of the present application, after step 101, the method may further include the following steps:

[0049] When the data space mode is the single data space mode, run the firmware program.

[0050] If the current data space mode is the single data space mode, the external devices are all configured in the same data space. Correspondingly, there is only the external device address of this data space. When running the firmware program, the server will not crash due to incorrect access to the external device address. Therefore, it is determined that the firmware program needs to be run.

[0051] Step 102: When the data space mode is the multi - data space mode, determine the running mode configured by the server for the firmware programs of at least two external devices; wherein, in the multi - data space mode, each external device is configured with a data space, and there are the same external device addresses in each data space.

[0052] If the current data space mode is the multi - data space mode, it is necessary to further determine the running mode configured by the server for the firmware programs of at least two external devices.

[0053] Step 103: When the running mode is the specified running mode, respectively determine the CPU information for processing the firmware programs of at least two external devices, and when the CPU information indicates that the current CPU is the specified CPU, skip running the firmware program to avoid server downtime caused by incorrect access to the external device address.

[0054] If the current running mode is the specified running mode, it is necessary to respectively determine the CPU information for processing the firmware programs of at least two external devices, so as to determine the current CPU indicated by the CPU information.

[0055] Whether it is the specified CPU. If the CPU information indicates that the current CPU is the specified CPU and the firmware program 5 is still continued to run, an access error will occur due to repeated traversal of the external device address. Therefore, it is necessary to skip running the firmware program to avoid server downtime caused by incorrect access to the external device address.

[0056] Among them, the specified running mode is the running mode that can run the firmware program; the specified CPU is the CPU other than the first running CPU.

[0057] In the embodiments of the present application, when at least two external devices are connected to the server, the data space mode configured by the server for the at least two external devices is determined. When the data space mode is a multi-data space mode, the operating mode configured by the server for the firmware program in the at least two external devices is determined. Wherein, in the multi-data space mode, each external device is configured with a data space, and the same external device address exists in each data space. When the operating mode is the specified operating mode, the CPU information for processing the firmware program in the at least two external devices is respectively determined. 5 And when the CPU information indicates that the current CPU is the specified CPU, the firmware program is skipped from running.

[0058] To avoid server downtime caused by incorrect access to the external device address, an external device processing method based on the configuration space and the operating mode is implemented, avoiding server downtime caused by incorrect access to the external device address when running the firmware program in the multi-data space mode, and without the need to provide additional hardware devices or occupy system resources, greatly improving the maintainability of the server system.

[0059] 0 Refer to Figure 2 , showing the step flowchart of another embodiment of the processing method for external devices in the server of the present application. The method may include the following steps:

[0060] Step 201, when at least two external devices are connected to the server, obtain the configuration space value configured by the server for the at least two external devices.

[0061] When starting the BIOS of the server, if at least two external devices are connected to the server, obtain the configuration space value configured by the server for the at least two external devices to determine the data space mode configured by the server for the at least

[0062] two external devices.

[0063] In some embodiments of the present application, before determining the data space mode configured by the server for the at least two external devices in step 201, the method may further include the following steps:

[0064] Pre-load the firmware program.

[0065] Since at least two external devices are connected to the server, when starting the BIOS of the server, the firmware program in the connected external devices will be pre-loaded, so that there is no need to re-load when it is determined that the firmware program needs to be run.

[0066] In some embodiments of the present application, obtaining the configuration space value configured by the server for the at least two external devices in step 201 may include the following sub-steps:

[0067] Sub-step 11: Scan at least two external devices to obtain a scan result.

[0068] When starting the BIOS of the server, scan at least two external devices to obtain a scan result for the external devices.

[0069] Sub-step 12: Determine the configuration space value configured by the server for at least two external devices according to the scan result.

[0070] After obtaining the scan result, since the scan result includes the configuration information of the external devices, the configuration space value configured by the server for at least two external devices can be determined according to the scan result.

[0071] Step 202: Determine the data space mode configured by the server for at least two external devices according to the configuration space value.

[0072] By analyzing the configuration space value, the data space mode configured by the server for at least two external devices can be determined.

[0073] In some embodiments of the present application, step 202 may include the following sub-steps:

[0074] Sub-step 21: When the configuration space value is greater than a preset value, determine that the data space mode configured by the server for at least two external devices is a multi-data space mode.

[0075] The preset value is the maximum memory value occupied by one data space. When the configuration space value is greater than the preset value, it can be determined that there is more than one current data space, and thus it is determined that the data space mode configured by the server for at least two external devices is a multi-data space mode.

[0076] Sub-step 22: When the configuration space value is less than the preset value, determine that the data space mode configured by the server for at least two external devices is a single-data space mode.

[0077] The preset value is the maximum memory value occupied by one data space. When the configuration space value is less than the preset value, it can be determined that there is only one current data space, and thus it is determined that the data space mode configured by the server for at least two external devices is a single-data space mode.

[0078] In some embodiments of the present application, after step 202, the method may further include the following steps:

[0079] When the data space mode is a single-data space mode, run the firmware program.

[0080] If the current data space mode is the single data space mode, the external devices are all configured in the same data space. Correspondingly, there is only the external device address of this data space, and the operation of the firmware program will not cause the server to crash due to incorrect access to the external device address. Therefore, it is determined that the firmware program needs to be run.

[0081] In some embodiments of the present application, the preset value may be 256M.

[0082] Step 203: In the case where the data space mode is the multi-data space mode, determine the operation mode configured by the server for the firmware programs of at least two external devices; wherein, in the multi-data space mode, each external device is configured with a data space, and the same external device address exists in each data space.

[0083] If the current data space mode is the multi-data space mode, it is necessary to further determine the operation mode configured by the server for the firmware programs of at least two external devices.

[0084] Step 204: In the case where the operation mode is the specified operation mode, respectively determine the CPU information for processing the firmware programs of at least two external devices, and in the case where the CPU information indicates that the current CPU is the specified CPU, skip running the firmware program to avoid server crashes caused by incorrect access to the external device address.

[0085] If the current operation mode is the specified operation mode, it is necessary to respectively determine the CPU information for processing the firmware programs of at least two external devices, so as to determine whether the current CPU indicated by the CPU information is the specified CPU. If the CPU information indicates that the current CPU is the specified CPU and the firmware program continues to run, an access error will occur due to repeated traversal of the external device address. Therefore, it is necessary to skip running the firmware program to avoid server crashes caused by incorrect access to the external device address.

[0086] Among them, the specified operation mode is the operation mode that can run the firmware program; the specified CPU is the CPU other than the first running CPU.

[0087] In the embodiments of the present application, when at least two external devices are connected to the server, the data space mode configured by the server for the at least two external devices is determined. When the data space mode is a multi-data space mode, the running mode configured by the server for the firmware programs in the at least two external devices is determined. Among them, in the multi-data space mode, each external device is configured with a data space, and the same external device address exists in each data space. When the running mode is the specified running mode, the CPU information for processing the firmware programs in the at least two external devices is determined respectively. When the CPU information indicates that the current CPU is the specified CPU, the running of the firmware programs is skipped to avoid server downtime caused by incorrect access to the external device address. A method for processing external devices based on the configuration space and running mode is implemented, avoiding server downtime caused by incorrect access to the external device address when running firmware programs in the multi-data space mode, without the need to provide additional hardware devices or occupy system resources, greatly improving the maintainability of the server system.

[0088] Referring to Figure 3 , a flowchart of steps of another embodiment of the method for processing external devices in the server according to the present application is shown. The method may include the following steps:

[0089] Step 301: When at least two external devices are connected to the server, determine the data space mode configured by the server for the at least two external devices.

[0090] When the BIOS of the server is started, if at least two external devices are connected to the server, the data space mode configured by the server for the at least two external devices is determined.

[0091] In some embodiments of the present application, before determining the data space mode configured by the server for the at least two external devices in step 301, the method may further include the following steps:

[0092] Preload the firmware programs.

[0093] Since at least two external devices are connected to the server, when the BIOS of the server is started, the firmware programs in the connected external devices are preloaded, so that there is no need to reload when it is determined that the firmware programs need to be run.

[0094] In some embodiments of the present application, after step 301, the method may further include the following steps:

[0095] When the data space mode is a single data space mode, run the firmware programs.

[0096] If the current data space mode is the single data space mode, the external devices are all configured in the same data space. Correspondingly, there is only the external device address of this data space, and running the firmware program will not cause the server to crash due to incorrect access to the external device address. Therefore, it is determined that the firmware program needs to be run.

[0097] Step 302: In the case where the data space mode is the multi-data space mode, determine the running mode configured by the server for the firmware programs of at least two external devices; wherein, in the multi-data space mode, each external device is configured with one data space, and the same external device address exists in each data space.

[0098] If the current data space mode is the multi-data space mode, it is necessary to further determine the running mode configured by the server for the firmware programs of at least two external devices.

[0099] Step 303: In the case where the running mode is the non-specified running mode, skip running the firmware program.

[0100] The non-specified running mode is a running mode that does not require running the firmware program. If the current running mode is the non-specified running mode, it is necessary to skip running the firmware program.

[0101] Step 304: In the case where the running mode is the specified running mode, respectively determine the CPU information for processing the firmware programs of at least two external devices, and in the case where the CPU information indicates that the current CPU is the specified CPU, skip running the firmware program to avoid the server crashing due to incorrect access to the external device address.

[0102] If the current running mode is the specified running mode, it is necessary to respectively determine the CPU information for processing the firmware programs of at least two external devices, so as to determine whether the current CPU indicated by the CPU information is the specified CPU. If the CPU information indicates that the current CPU is the specified CPU and the firmware program continues to run, an access error will occur due to repeated traversal of the external device address. Therefore, it is necessary to skip running the firmware program to avoid the server crashing due to incorrect access to the external device address.

[0103] Among them, the specified running mode is a running mode that can run the firmware program; the specified CPU is the CPU other than the first running CPU.

[0104] In an embodiment of the present application, when at least two external devices are connected to the server, the data space mode configured by the server for the at least two external devices is determined. When the data space mode is a multi-data space mode, the operating mode configured by the server for the firmware programs in the at least two external devices is determined. Among them, in the multi-data space mode, each external device is configured with a data space, and the same external device address exists in each data space. When the operating mode is a specified operating mode, the CPU information for processing the firmware programs in the at least two external devices is determined respectively. When the CPU information indicates that the current CPU is a specified CPU, the firmware program is skipped to avoid server downtime caused by incorrect access to the external device address. An external device processing method based on the configuration space and the operating mode is implemented, avoiding server downtime caused by incorrect access to the external device address when running the firmware program in the multi-data space mode, without the need to provide additional hardware devices and without occupying system resources, greatly improving the maintainability of the server system.

[0105] Referring to Figure 4 , a step flowchart of another embodiment of the external device processing method based on the server in the present application is shown. The method may include the following steps:

[0106] Step 401, when at least two external devices are connected to the server, determine the data space mode configured by the server for the at least two external devices.

[0107] When the BIOS of the server is started, if at least two external devices are already connected to the server, the data space mode configured by the server for the at least two external devices is determined.

[0108] In some embodiments of the present application, before determining the data space mode configured by the server for the at least two external devices in step 401, the method may further include the following steps:

[0109] Preload the firmware program.

[0110] Since at least two external devices are connected to the server, when the BIOS of the server is started, the firmware programs in the connected external devices are preloaded, so that there is no need to reload when it is determined that the firmware program needs to be run.

[0111] In some embodiments of the present application, after step 401, the method may further include the following steps:

[0112] When the data space mode is a single data space mode, run the firmware program.

[0113] If the current data space mode is the single data space mode, external devices are all configured in the same data space. Correspondingly, there is only the external device address of this data space, and the running of the firmware program will not cause the server to crash due to incorrect access to the external device address. Therefore, it is determined that the firmware program needs to be run.

[0114] Step 402: In the case where the data space mode is the multi - data space mode, determine the running mode configured by the server for the firmware programs of at least two external devices; wherein, in the multi - data space mode, each external device is configured with one data space, and the same external device address exists in each data space.

[0115] If the current data space mode is the multi - data space mode, it is necessary to further determine the running mode configured by the server for the firmware programs of at least two external devices.

[0116] Step 403: In the case where the running mode is the specified running mode, respectively determine the CPU information for processing the firmware programs of at least two external devices, and in the case where the CPU information indicates that the current CPU is the specified CPU, skip running the firmware program to avoid server crashes caused by incorrect access to the external device address.

[0117] If the current running mode is the specified running mode, it is necessary to respectively determine the CPU information for processing the firmware programs of at least two external devices, so as to determine whether the current CPU indicated by the CPU information is the specified CPU. If the CPU information indicates that the current CPU is the specified CPU and the firmware program is still continued to run, access errors will occur due to repeated traversal of the external device address. Therefore, it is necessary to skip running the firmware program to avoid server crashes caused by incorrect access to the external device address.

[0118] Among them, the specified running mode is the running mode that can run the firmware program; the specified CPU is the CPU other than the first running CPU.

[0119] Step 404: In the case where the CPU information indicates that the current CPU is a non - specified CPU, run the firmware program.

[0120] The non - specified CPU is the first running CPU. Therefore, when it is necessary to traverse the external device address, only access the external device address in the data space corresponding to the first running CPU to complete the traversal, and there is no need to access the external device address in the data space corresponding to other CPUs. Therefore, if the CPU information indicates that the current CPU is a non - specified CPU, the firmware program can be run.

[0121] In the embodiments of the present application, when at least two external devices are connected to the server, the data space mode configured by the server for the at least two external devices is determined. When the data space mode is the multi-data space mode, the operation mode configured by the server for the firmware programs in the at least two external devices is determined. Among them, in the multi-data space mode, each external device is configured with a data space, and the same external device address exists in each data space. When the operation mode is the specified operation mode, the CPU information for processing the firmware programs in the at least two external devices is determined respectively. When the CPU information indicates that the current CPU is the specified CPU, the firmware program is skipped to avoid server downtime caused by incorrect access to the external device address. A method for processing external devices based on the configuration space and operation mode is implemented, avoiding server downtime caused by incorrect access to the external device address when the firmware program is running in the multi-data space mode, without the need to provide additional hardware devices or occupy system resources, greatly improving the maintainability of the server system.

[0122] The following describes the step processes involved in the above multiple method embodiments:

[0123] As Figure 5 shown, the method embodiment for processing external devices in the server of the present application may include the following processes:

[0124] 1) The BIOS boots up.

[0125] 2) Scan the external PCIe card devices (i.e., external devices) to obtain the scan results.

[0126] 3) Prepare to load the external card legacy option rom (i.e., firmware program).

[0127] 4) According to the scan results, determine whether the PCI configuration space size option (i.e., configuration space value) is

[0128] greater than 256M. If so, determine that the current is the multi-segment mode (i.e., multi-data space mode), and 5 further determine the startup mode (i.e., the operation mode configured by the server for the firmware programs in the at least two external devices). If not, determine that the current is the single-segment mode (i.e., single-data space mode), and execute the external card legacy option rom.

[0129] 5) Determine whether the startup mode selection option selects the Legacy mode (i.e., specified operation mode).

[0130] 5) Determine whether the startup mode selection option selects the Legacy mode (i.e., specified operation mode).

[0131] If so, further determine whether the current external card is the card connected to CPU1 (i.e., the specified CPU). If not, skip and execute the legacy option rom of this external card.

[0132] 6) Determine whether the current external card is the card connected to CPU1. If so, skip and execute the legacy option rom of this external card. If not, execute the legacy option rom of this external card.

[0133] 7) After executing the legacy option rom of the external card, continue to execute the subsequent other codes of the BIOS.
