Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

One of the core concepts of the embodiments of the present invention is to move a BIOS start file in a storage to a memory of a Central Processing Unit (CPU) based on a bus between the CPU and the storage and a BIOS move code file, and start a BIOS of an electronic device in the memory of the CPU. Therefore, the method for starting the BIOS based on the bus is realized, so that the BIOS is not limited to be started only at the stored position, and the limitation of a starting mode can be reduced to a certain extent. Meanwhile, the BIOS starting file is moved and copied to the memory of the CPU and is started in the memory of the CPU, so that the starting efficiency of the BIOS can be improved to a certain extent.

Referring to fig. 1, a flow chart of steps of an embodiment of a BIOS startup method of the present invention is shown, and the method may be applied to an electronic device including a CPU and a memory for storing BIOS startup files, where the CPU and the memory are connected by a bus. The method specifically comprises the following steps:

step 101, responding to a system starting instruction, and determining an execution area of a BIOS moving code file according to the storage structure type of the CPU; the storage structure type is used for representing whether the CPU supports cache access to the bus space of the bus.

In an embodiment of the present invention, the memory may be a flash, and the bus is a Peripheral Component Interconnect (PCI) or PCIE. The CPU may refer to a main CPU in the electronic device.

The system boot instruction may be used to instruct booting the BIOS in the electronic device, and may be generated, for example, during an initial power-on phase to boot the BIOS in the electronic device first. The BIOS move code file may be preset and may include a code file for moving the BIOS boot file from the memory to the memory of the CPU. By operating the BIOS to move the code file, the BIOS starting file in the memory can be copied to the memory of the CPU. The BIOS starting file may be a preset file for starting the BIOS, and the BIOS starting file may be a program, that is, a set of code files. Specifically, the BIOS boot file may be a BIOS system file itself.

Further, the storage structure type may be used to characterize whether the CPU supports cache access to the bus space of the bus. The bus space may refer to a space allocated to a bus by the CPU, and the execution region refers to a region for executing the BIOS move code file.

Optionally, in an implementation manner, the step of determining an execution area of the BIOS moving the code file according to the storage structure type of the CPU may specifically include the following steps:

and step 1011, determining the cache as the execution area under the condition that the storage structure type represents that the CPU supports cache access to the bus space of the bus.

Step 1012, determining the memory of the CPU as the execution area when the storage structure type indicates that the CPU does not support cache access to the bus space of the bus.

In an actual application scenario, CPUs used by electronic devices may have differences, and some storage structures of CPUs may include a storage space cache, where the storage space cache may specifically refer to a cache memory inserted between a CPU register and a CPU main memory. The CPU main memory may be the memory of the aforementioned CPU. For example, some CPUs use a storage system that includes registers, a memory space cache for a block area, and a memory. However, some CPU storage structures do not include a cache for a block area, and accordingly, a cache access mode cannot be adopted. The storage structure type can be divided into two types, namely a storage space cache type and a non-storage space cache type, and correspondingly, the storage structure type comprising the storage space cache can represent that the CPU supports cache access to the bus space of the bus, and the storage structure type not comprising the storage space cache can represent that the CPU does not support cache access to the bus space of the bus.

In the embodiment of the present invention, the model of the CPU including the memory space cache in the memory structure, that is, the model of the CPU supporting the cache access to the bus space of the bus, may be collected in advance. The model of the CPU used in the current electronic device is obtained, for example, the parameter information of the CPU in the current electronic device is read, and the model of the CPU is obtained. And then, comparing the acquired model with the model of the CPU collected in advance, and if the model is hit, determining that the storage structure of the CPU comprises a storage space cache, wherein the type of the storage structure of the CPU supports cache access to a bus space of a bus. Otherwise, it may be determined that the CPU storage structure does not include a storage space cache, and the CPU storage structure type does not support cache access to the bus space of the bus.

Accordingly, in the case where the CPU supports cache access to the bus space, and the cache is determined as the execution region, the BIOS move code file may be prefetched from the designated region into the cache based on the bus space. The specified area is an area in which the BIOS move code is stored. In the embodiment of the invention, the cache is determined as the execution area under the condition that the storage structure type representation CPU supports cache access to the bus space of the bus. And under the condition that the storage structure type represents that the CPU does not support cache access to the bus space of the bus, determining the memory of the CPU as an execution area. Because the program running speed in the cache is higher, the running efficiency of the BIOS for moving the codes can be improved to a certain extent, and the starting speed of the BIOS is improved.

And 102, executing the BIOS moving code file in the execution area so as to move the BIOS starting file stored in the storage to the memory of the CPU through the bus.

In the embodiment of the invention, the BIOS can be executed by jumping to the execution area. Accordingly, by executing the BIOS move code file, the BIOS boot file stored in the memory can be moved to the memory of the CPU. Because the memory is connected with the CPU based on the PCI/PCIE bus, the moved BIOS starting file can reach the memory of the CPU through the PCI/PCIE bus. For example, the BIOS move code file may first move the BIOS boot file to the memory of the CPU via the PCI/PCIE bus.

Step 103, starting the BIOS of the electronic device in the memory of the CPU based on the BIOS start file.

Illustratively, the BIOS start-up file may be run, thereby enabling the BIOS to start up in the memory of the CPU.

In summary, in the BIOS starting method provided in the embodiment of the present invention, in response to a system start instruction, according to the storage structure type of the CPU, the execution area of the BIOS moving the code file is determined; the memory structure type is used for representing whether the CPU supports cache access to the bus space of the bus. And executing the BIOS moving code file in the execution area to move the BIOS starting file stored in the memory to the memory of the CPU through the bus. And starting the BIOS of the electronic equipment in the memory of the CPU based on the BIOS starting file. In the embodiment of the invention, the BIOS starting file in the storage is moved to the memory of the CPU based on the bus between the CPU and the storage and the BIOS moving code file, and the BIOS of the electronic equipment is started in the memory of the CPU. Therefore, the method for starting the BIOS based on the bus is realized, so that the BIOS is not limited to be started only at the stored position, and the limitation of the starting mode can be further reduced to a certain extent.

Meanwhile, the BIOS starting file is moved and copied to the memory of the CPU and is started in the memory of the CPU, so that the starting efficiency of the BIOS can be improved to a certain extent.

Optionally, in this embodiment of the present invention, the electronic device may further include an intermediate device, and the intermediate device is connected to the CPU and the memory through the bus, respectively, that is, the CPU and the intermediate device are linked through a PCI/PCIE bus, and the intermediate device and the memory are linked through a PCI/PCIE bus. Correspondingly, before the step of determining the execution area of the BIOS moving the code file according to the storage structure type of the CPU, the following steps may be performed in an embodiment of the present invention:

step 201, under the condition that the CPU is determined to be included in the intermediate device, suspending the CPU included in the intermediate device.

The CPU included in the intermediate Device may be a bridge chip with a CPU core, and the intermediate Device may be a bridge chip or other devices, such as a Field Programmable Gate Array (FPGA) or a Complex Programmable Logic Device (CPLD). Fig. 2 is a schematic diagram of a hardware link according to an embodiment of the present invention, and as shown in fig. 2, a CPU of an electronic device may be linked with an intermediate device through a PCI/PCIE bus, and a memory may be connected behind the intermediate device. The memory may also be attached to the intermediate device, for example, the memory may be a flash attached to the bridge chip. The hardware link mode of the processor shown in fig. 2 may support the method for starting the BIOS based on the PCI/PCIE bus in the embodiment of the present invention.

Specifically, a shutdown instruction may be sent to the CPU included in the intermediate device in the CPU initialization stage to suspend the CPU included in the intermediate device.

Because some intermediate devices are provided with additional CPUs, in the embodiments of the present invention, the CPUs included in the intermediate devices can be suspended when the CPUs are included in the intermediate devices, so as to avoid a conflict between the CPUs included in the intermediate devices and the CPUs of the electronic devices, for example, the CPUs included in the intermediate devices access the memory at the same time, and fetch an instruction in the activated memory, so as to generate a conflict, thereby ensuring that subsequent operations can be performed normally.

Accordingly, during the operation of the above-described CPU, the CPU included in the intermediate device may be controlled not to operate at all times to avoid a collision as much as possible.

Optionally, before executing step 201, in the embodiment of the present invention, determining whether the intermediate device includes a CPU by the following steps, that is, determining that the intermediate device includes a CPU may include:

and 301, acquiring the device type of the intermediate device.

Specifically, type parameters for characterizing the device type of the intermediate device may be obtained from parameter data of the intermediate device. And searching the device type corresponding to the obtained type parameter based on the preset corresponding relation between the device type and the type parameter, and further obtaining the device type of the intermediate device.

Step 302, determining that the intermediate device comprises a CPU when the device type is a first specified type.

Wherein the first specified type is to support a device type including a CPU. The first specified type may be a pre-collected device type that supports including a CPU. For example, a bridge may include a CPU, i.e., the bridge supports including a CPU, while an FPGA may not include a CPU, i.e., the FPGA does not support including a CPU. Accordingly, the first specified type may include a bridge chip and not an FPGA. In the embodiment of the invention, the CPU device type can be included as the first specified type.

Since functions of electronic devices are enriched at present, devices including CPUs are often configured for electronic devices to support the devices including CPUs. Therefore, in the embodiment of the present invention, when the device type is the first designated type, it may be determined that the intermediate device includes the CPU, and thus, efficiency may be ensured to a certain extent. Conversely, if the device type is not the first specified type, it may be determined that the CPU is not included in the intermediate device.

It should be noted that, in the embodiment of the present invention, when the device type is the first specified type, the configuration information of the intermediate device may be further detected, and when the configuration information of the intermediate device indicates that the CPU is configured in the intermediate device, it is determined that the CPU is included in the intermediate device, so as to ensure accuracy of the determination operation. And whether the device type is the first appointed type is determined, and the device is further detected under the condition that the device type is the first appointed type, so that unnecessary detection of the device which does not support the CPU can be avoided, and processing resources are saved to a certain extent.

Optionally, the following steps may also be executed in the embodiment of the present invention:

step 401, in a case that the device type of the intermediate device is a second specified type, after the BIOS boot file stored in the storage is moved to the memory of the CPU through the bus, initializing the intermediate device; wherein initialization of the second specified type of intermediate device comprises an address update operation to the memory.

In the embodiment of the present invention, the execution sequence of the initialization operation of the intermediate device may be adjusted to a sequence after the step of transferring the BIOS boot file stored in the storage to the memory of the CPU through the bus. The second specified type may be preset, and specifically, a device type that updates an address of the memory in the initialization stage may be collected in advance, for example, if the address of the memory is updated in the initialization stage of a certain device, the device type may be the second specified type. Wherein the second specified type may exist for the same device type as the first specified type. For example, the first specified type may include a bridge piece.

Specifically, an initialization prohibition instruction may be issued to the intermediate device, and accordingly, after the step of moving the BIOS startup file stored in the storage to the memory of the CPU through the bus is executed, an initialization prohibition instruction is issued to the intermediate device, so that the execution order of the initialization operation of the intermediate device is adjusted to be after the BIOS startup file is moved to the memory, and the intermediate device executes the initialization operation after the BIOS startup file is moved to the memory.

Illustratively, in the case where the intermediate device is a bridge chip, the window needs to be reconfigured for the bridge chip, i.e., the memory needs to be re-scribed for the bridge chip, and the bridge chip is initialized. If the execution sequence of the initialization operation is not adjusted, the initialization operation of the bridge chip can cause the address of the memory to change, which causes the address of the data in the memory to change, further causes the CPU not to address normally, and cannot acquire the data in the memory. Of course, if the intermediate device is a device whose initialization does not update the address of the memory, for example, FPGA, the intermediate device may be normally initialized without adjusting the sequence.

In the embodiment of the invention, under the condition that the address of the memory is updated by the initialization of the intermediate device, the execution sequence of the initialization operation of the intermediate device is adjusted, and the intermediate device is initialized after the BIOS starting file stored in the memory is moved to the memory of the CPU through the bus. The address of the storage is prevented from changing before the BIOS starting file is moved to the memory of the CPU, and further the problem that the BIOS cannot be started in the CPU due to the fact that the BIOS starting file cannot be acquired is avoided.

Optionally, in this embodiment of the present invention, the BIOS moving code file may be stored in a memory storing the BIOS file in advance. Of course, in practical applications, the information may also be stored in other locations, for example, in other memories, and the embodiment of the present invention is not limited thereto. Taking the case that the BIOS moving code file is pre-stored in the memory for storing the BIOS file, when the storage structure type characterization CPU does not support cache access to the bus space in which the BIOS start file is stored in the memory, and the execution area is the memory, the following steps may be further performed in the embodiment of the present invention:

step 501, copying the entry function code, the BIOS moving code file, and the abnormal output code in the memory to the memory. Accordingly, the BIOS can be skipped to the memory to run the code file.

Correspondingly, the step of executing the BIOS moving the code file based on the execution area may specifically include: and executing the entry function code in the memory to call and run the BIOS transfer code file.

The entry function code may be a C entry function code, and the entry function code may define a call logic, and accordingly, the BIOS move code file may be called by executing the entry function code, and then the BIOS move code file may be run, so that the BIOS start file may reach the memory of the CPU from the flash of the bridge chip through the PCI/PCIE bus.

Therefore, the BIOS can be executed by directly starting to execute the entry function code, and the execution effect can be ensured to a certain extent.

Further, the following operations may also be performed in the embodiment of the present invention: and outputting exception information based on the exception output code when an error occurs in operation. The abnormal output code may be an abnormal print code, and the abnormal output code may be used to locate and output the location information of the fault. If the BIOS moving code has an error in operation, the abnormal output code can be further operated so as to acquire the position information with the fault as the abnormal information and output the abnormal information. Because the BIOS moving code file is copied into the memory for execution, the abnormal output code is further copied into the memory in the embodiment of the invention, so that the abnormal information can be conveniently obtained under the condition of operation error, and further, the fault is conveniently positioned.

Further, in a case that the execution area is a cache of the CPU, the step of executing the BIOS moving the code file based on the execution area may specifically include: and pulling the BIOS moving code file in the memory based on the cache, and executing the pulled BIOS moving code file.

The BIOS moving code file can comprise a plurality of instructions, one instruction can correspond to the other instruction, a part of the BIOS moving code file which can be executed independently can be executed, and moving can be achieved by executing the instructions. In the embodiment of the invention, the cache of the CPU can be initialized firstly. And then, taking the instruction corresponding to the BIOS moving code file from the cache of the CPU and executing the instruction. For the cache access mechanism, if the cache does not exist, a part of instructions are fetched from the memory and executed, and correspondingly, other subsequent parts are written into the cache, so that the cache can be directly accessed for execution subsequently, and the processing speed is further ensured. It should be noted that, in an actual application scenario, an instruction forming an entry function code may be taken first, and an instruction in a BIOS transfer code file that needs to be called is taken in an execution process. It should be noted that, in a case where the CPU supports cache access to a bus space of the bus, in an implementation manner, since the CPU is connected to the memory through the PCI/PCIE bus, when an instruction is fetched from the cache, the instruction may be prefetched into the cache through the PCI/PCIE bus space of the PCI/PCIE bus. For example, the command is first fetched from the designated area storing the BIOS move code to the bus space based on the PCI/PCIE bus, and then the command is fetched from the bus space to the cache. It should be noted that, in an actual application scenario, the BIOS shift code file may also be stored in the cache in advance, so that the BIOS shift code file is directly executed in the cache.

FIG. 3 is a process flow diagram of an embodiment of the present invention, as shown in FIG. 3, for suspending a CPU included in a bridge chip in the case that the CPU is included in the bridge chip. Otherwise, if not, the subsequent operation can be directly performed. Specifically, after power-on, whether the bridge chip includes the CPU may be detected. Further, in the case that the main CPU of the electronic device supports cache access, jumping to the cache and executing the BIOS move code file. Under the condition that a main CPU of the electronic equipment does not support cache access, copying the BIOS moving code file into a memory, and jumping to the memory to execute the BIOS moving code file. The supporting of the cache access by the main CPU may specifically refer to that the main CPU supports the cache access to the bus space of the bus, that is, the cache of the main CPU supports the access to the bus space. And then, moving the BIOS starting file to a memory of the CPU, and starting the BIOS based on the BIOS starting file. And after the BIOS starting file is moved to the memory of the CPU, the bridge chip is initialized. Of course, the initialization operation may be performed on the bridge after the BIOS is successfully started based on the BIOS start file, which is not limited in this embodiment of the present invention.

At present, BIOS starting files are often placed in memories such as nor and nand flash, and can only be started in memories such as nor and nand flash. In the embodiment of the invention, the CPU of the electronic equipment supports the BIOS starting based on the PCI/PCIE, and the method for starting the BIOS in the CPU based on the PCI/PCIE solves the problem that the BIOS can only be started in memories such as nor and nand flash, and provides a new alternative for hardware construction. And different treatments are carried out on the intermediate device according to actual conditions, so that the normal starting of the BIOS is ensured, and the normal starting of the operating system is guided.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those of skill in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the embodiments of the invention.
