Description

Method, device and equipment for starting hard disk firmware

Technical Field

The present application relates to the field of hard disk technologies, and in particular, to a method, an apparatus, and a device for starting a hard disk firmware.

Background

Electronic devices (e.g., servers, computers, etc.) are generally provided with a hard disk interface through which a hard disk can be inserted into the electronic device so that the electronic device can use the hard disk through the hard disk interface. In order to ensure that the hard disk can normally operate, firmware needs to be loaded in the hard disk, and the hard disk is controlled by the firmware, for example, the hard disk can be driven and detected by the firmware. The firmware is realized by software, and the firmware of the hard disk can be upgraded according to actual needs.

In the prior art, firmware is usually fixedly stored in a hard disk, and after the hard disk is started, the stored firmware is directly loaded. When the firmware needs to be upgraded, the electronic equipment obtains the latest firmware, and the electronic equipment independently upgrades the firmware in each hard disk. When the firmware in the hard disk is upgraded, the electronic device and each hard disk need to interact for many times, the firmware in the hard disk can be upgraded only by storing the firmware of the latest version in the position area of the fixed storage firmware preset by each hard disk and deleting the firmware of the old version fixedly stored in the position area of the fixed storage firmware.

However, in the practical application process, when the number of hard disks in the electronic device is large, the electronic device needs to update and maintain the firmware in each hard disk, and needs to maintain the location area of the fixed storage firmware preset in each hard disk, which results in a complicated firmware maintenance process.

Disclosure of Invention

The application provides a method, a device and equipment for starting a hard disk firmware, which simplify the maintenance process of the firmware.

In a first aspect, the present application provides a method for starting a hard disk firmware, where after determining that a hard disk is powered on or reset, a hard disk controller obtains location information of the firmware in a memory of an electronic device, obtains the firmware in the memory of the electronic device in a DMA manner according to the location information, and stores the firmware in the memory of the hard disk.

In the above process, the storage medium of the hard disk does not permanently store the firmware, but after the hard disk is powered on or reset each time, the latest firmware is acquired from the memory of the electronic device, and the acquired latest firmware is directly started in the hard disk. Therefore, the firmware in the hard disk can be ensured to be the latest firmware all the time, and further, the electronic equipment does not need to maintain the firmware in each hard disk independently because the firmware is not stored in the hard disk permanently, so that the maintenance process of the firmware is simplified.

Optionally, the location information includes a start address of the firmware in the memory of the electronic device and a size of the firmware; alternatively, the location information includes a start address and an end address of the firmware in a memory of the electronic device. Optionally, when the location information includes a start address and an end address of the firmware in the memory of the electronic device, a continuous storage space for storing the firmware is located between the start address and the end address.

In one possible embodiment, the hard disk controller may obtain the location information by querying a first register of the hard disk.

Optionally, before the hard disk controller obtains the location information, the hard disk controller may first query a value in a second register of the hard disk, and when it is determined that the value in the second register is the first preset value, the hard disk controller obtains the location information by querying the first register of the hard disk.

In the above process, when the first register is a nonvolatile memory, after the hard disk is powered on or reset, the value in the first register is a value written by the hard disk in the last operation process, and the location information of the firmware in the memory of the electronic device may be different in different operation processes of the hard disk. When the hard disk controller inquires that the value in the second register is the first preset value, the position information in the first register can be determined to be written in the current operation process of the hard disk, namely, the position information in the first register is correct, so that the hard disk controller can be prevented from obtaining wrong position information.

In another possible implementation, when the hard disk controller obtains the firmware in the memory of the electronic device in the DMA manner, the hard disk controller may first query a value in a third register of the hard disk, and when it is determined that the value in the third register is the second preset value, the hard disk controller obtains the firmware in the memory of the electronic device in the DMA manner according to the location information.

In the above process, after the hard disk controller obtains the location information, the electronic device controller may not complete storing the firmware in the memory of the electronic device, and at this time, the hard disk controller may not successfully obtain the firmware in the memory of the electronic device. When the hard disk controller inquires that the value in the third register is the second preset value, the firmware is stored in the memory, and at this time, the hard disk controller can successfully acquire the firmware from the memory of the electronic device. Therefore, the hard disk controller can be prevented from carrying out invalid acquisition operation in the memory of the electronic equipment, and resource waste is further avoided.

In another possible implementation, the hard disk controller generally needs to acquire the firmware in the memory of the electronic device through the data bus, and in order to determine that the hard disk controller can successfully acquire the firmware, it is necessary to ensure that the link device of the data bus is in a normal state.

In a possible embodiment, in order to ensure that the hard disk controller can obtain correct location information, after the electronic device controller stores the location information of the firmware in the memory of the electronic device into the first register of the hard disk, the value in the second register of the hard disk may be set to a first preset value, where the first preset value is used to instruct the hard disk controller to obtain the location information in the first register.

In another possible embodiment, in order to avoid resource waste caused by the hard disk controller performing an invalid acquiring operation in the memory of the electronic device, after the electronic device controller stores the firmware in the memory of the electronic device, a value in a third register of the hard disk may be set to a second preset value, where the second preset value is used to instruct the hard disk controller to acquire the firmware in the memory of the electronic device in a DMA manner.

Detailed Description

Fig. 1 is a block diagram of a storage system provided in the present application. Referring to fig. 1, an electronic device control 11 and at least one hard disk 12 are included.

The electronic device controller 11 is connected to a host computer (not shown in the drawings) via a Storage Area Network (SAN). The electronic device controller 11 may be a computing device such as a server, desktop computer, or the like. The electronic device controller 11 is provided with a writing system and an application program. The electronic device controller 11 may receive an input output (I/O) request from a host. The electronic device controller 11 may also store data carried in the I/O request and write the data to the hard disk 12. The electronic device controller 11 belongs to a system controller, which is a separate device, different from the control chip in the hard disk 12. The present embodiment refers to the control chip of the hard disk 12 as a hard disk controller.

The hard disk 12 is a memory using a flash memory chip as a storage medium, and the hard disk 12 may also be referred to as a Solid State Drive (SSD) in this application.

Fig. 2 is a diagram illustrating a structure of the electronic device controller in fig. 1 according to the present application. Referring to fig. 2, the electronic device controller 11 includes an interface card 110, a memory 111, a processor 112, and an interface card 113.

Interface card 110 for communicating with a host and for receiving instructions sent by the host, and electronic device controller 11 may receive write instructions from the host through interface card 110.

And an interface card 113 for communicating with the hard disk 12, and the electronic device controller 11 may transmit a write data command to the hard disk 12 through the interface card 113 for storage.

The processor 112 is a Central Processing Unit (CPU). In embodiments of the present invention, the processor 112 may be used to receive write instructions or read instructions from a host and process these instructions. The processor 112 may also send the data in the write command to the hard disk 12.

Memory 111, including volatile memory, non-volatile memory, or a combination thereof. Volatile memory is, for example, random-access memory (RAM). The non-volatile memory is, for example, a floppy disk, a hard disk 12, a Solid State Disk (SSD), an optical disk, or various machine-readable media capable of storing program codes. The memory 111 has a power-saving function, which means that data stored in the memory 111 cannot be lost when the system is powered off and powered on again. The memory 111 may have one or more memories for temporarily storing data received from the host or data read from the hard disk 12, for example, when the electronic device controller 11 receives a plurality of write commands sent by the host, the data in the plurality of write commands may be temporarily stored in the memory 111.

Fig. 3 is a structural diagram of the hard disk in fig. 1 provided in the present application. Referring to fig. 3, the hard disk 12 includes a hard disk controller 121, a memory 122, a storage medium 123, and at least one register 124.

The hard disk controller 121 may be a control chip in the hard disk 12, and is configured to control the hard disk 12.

The memory 122, which may also be referred to as an internal memory, is used for temporarily storing operation data in the processor and data exchanged with other memories. The memory 122 may be volatile memory such as random-access memory (RAM). The memory 122 does not have a power conservation function, i.e., the data stored in the memory 121 is lost when the hard disk 12 is powered down and powered up again.

The storage medium 123 is typically a non-volatile memory, for example, a non-volatile memory such as a floppy disk, a hard disk, an SSD, an optical disk, and various machine-readable media that can store program codes. The storage medium 123 has a power-saving function, that is, when the hard disk 12 is powered down and powered up again, the data stored in the storage medium 123 is not lost.

The register 124 is used for temporarily storing information such as instructions, data and addresses. For example, the register 124 may include a data register for storing an integer number, an address register for storing an address, an instruction register for storing an instruction, and the like, and during an actual application process, the number of the registers 124 and data stored in the registers may be set according to actual needs, which is not specifically limited in this embodiment of the present application.

In the present application, the firmware is not permanently stored in the storage medium of the hard disk 12, but the latest firmware is acquired in the memory of the electronic device after the hard disk 12 is powered on or reset each time, and the acquired latest firmware is directly started in the hard disk 12. Therefore, the firmware in the hard disk 12 can be ensured to be the latest firmware all the time, and further, the electronic device does not need to maintain the firmware in each hard disk 12 independently because the firmware is not stored in the hard disk 12 permanently, thereby simplifying the maintenance process of the firmware.

The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may be combined with each other, and the description of the same or similar contents in different embodiments is not repeated.

Fig. 4 is a first flowchart illustrating a hard disk firmware boot method provided in the present application. Referring to fig. 4, the method may include:

s401, after the electronic device controller 11 is started, the electronic device controller 11 acquires the latest firmware.

At least one hard disk 12 may be inserted in the electronic device shown in the present application. For example, the electronic device may be a computer, a server, or the like, and of course, the electronic device may also be of other types, which is not specifically limited in this application.

Alternatively, the electronic device controller 11 may obtain the latest firmware in other devices through a network, or the electronic device controller 11 may also obtain the latest firmware in a local preset memory, where the latest firmware in the local preset memory may be maintained by a worker. Of course, the electronic device controller 11 may also obtain the latest firmware through other possible implementations.

S402, the electronic device controller 11 stores the firmware in the memory of the electronic device.

The memory of the electronic device is typically a non-permanent storage medium, i.e., the contents of the memory of the electronic device will be lost after the electronic device is powered off, so the electronic device controller 11 needs to store the latest firmware in the memory of the electronic device after each boot-up of the electronic device (or the electronic device controller 11).

Optionally, the electronic device controller 11 may apply for a storage space with a suitable size in the memory of the electronic device according to the size of the firmware, and store the firmware in the storage space obtained by the application.

Optionally, after the size of the firmware is usually within the preset range, the electronic device controller 11 may further use a part of the fixed storage space in the memory as the storage space for storing the firmware. In this way, when the electronic device controller 11 needs to store the firmware in the memory of the electronic device, the firmware may be directly stored in the fixed storage space.

Optionally, a firmware management module is disposed in the electronic device, the firmware management module is usually implemented by software, and in a process of managing the firmware by the electronic device controller 11, the electronic device controller 11 may load the firmware management module to a memory of the electronic device and execute a program instruction corresponding to the firmware management module, so as to implement the function shown in S401. Therefore, when the management mode of the firmware needs to be updated, only the program instruction in the firmware management module needs to be updated, so that the flexibility of managing the firmware is better.

S403, the electronic device controller 11 stores the location information of the firmware in the memory of the electronic device in the first register of the hard disk 12.

Alternatively, the first register of the hard disk 12 is typically only used to store the location information of the firmware in the memory of the electronic device.

After the electronic device controller 11 stores the firmware in the memory of the electronic device, the electronic device controller 11 acquires the location information of the firmware in the memory of the electronic device and writes the location information of the firmware in the memory of the electronic device into the first register of the hard disk 12.

Alternatively, the electronic device controller 11 may write the position information to the first register through a data bus.

In S401, when the electronic device controller 11 stores the firmware in the fixed storage space in the memory of the electronic device and the first register of the hard disk 12 is the nonvolatile memory, the electronic device controller 11 only needs to write the location information once into the first register. That is, the electronic device controller 11 only needs to write the location information of the firmware in the memory of the electronic device into the first register when the electronic device is first started, and the electronic device controller 11 does not need to write the location information of the firmware in the memory of the electronic device into the first register when the electronic device is subsequently started (after the second time and after the second time).

That is, in the second and subsequent boot processes of the electronic device, S403 is an optional step. Therefore, in the second and later starting processes of the electronic equipment, the information interaction process can be simplified, and the starting efficiency of the firmware is improved.

Optionally, the hard disk controller 121 generally has a link management function, and after the hard disk 12 is powered on, the hard disk controller 121 may determine the link state of the data bus of the electronic device by querying the fourth register of the hard disk 12, and repair the data bus when the hard disk controller 121 determines that the link state is the abnormal state until the link state of the data bus is switched to the normal state.

Optionally, the fourth register is generally only used for storing the link status of the data bus, for example, when the value in the fourth register is 1, the link status of the data bus is determined to be a normal status, and when the value in the fourth register is 0, the link status of the data bus is determined to be an abnormal status. Optionally, the fourth register is typically a read-only memory.

Alternatively, the hard disk controller 121 may repair the data bus by the following feasible implementation manners: the hard disk controller 121 modifies the value of the fifth register to reset the communication link of the data bus, and the hard disk controller 121 modifies the value of the sixth register to establish the communication link of the data bus.

Optionally, the fifth register is a readable and writable register, and when the value in the fifth register is the corresponding preset value, the data bus is reset.

Optionally, the sixth register is a readable and writable register, and when the value in the sixth register is the corresponding preset value, the communication link of the data bus is established.

Of course, the link status of the data bus may also be managed by the electronic device controller 11, which is not specifically limited in this application.

It should be noted that, before S402, the electronic device controller 11 needs to determine the location information of the firmware in the memory of the electronic device, and accordingly, S402 and S403 may be executed sequentially or simultaneously, and the execution sequence of S402 and S403 is not specifically limited in this embodiment of the application.

S404, after determining that the hard disk 12 is powered on or reset, the hard disk controller 121 obtains the location information of the firmware in the memory of the electronic device by querying the first register.

In practical applications, after the electronic device is started, the electronic device usually supplies power to the interface of the hard disk 12 corresponding to the hard disk 12 to power on the hard disk 12 inserted in the electronic device, so that the hard disk 12 inserted in the electronic device can be powered on within a short period of time after the electronic device is started.

Of course, during the operation of the electronic device and the hard disk 12, the hard disk 12 may be reset by a preset instruction.

Optionally, after determining that the hard disk 12 is powered on or reset, the hard disk controller 121 queries the first register of the hard disk 12 to obtain the location information of the firmware in the memory of the electronic device.

Optionally, the location information includes a start address of the firmware in the memory and a size of the firmware; or the position information comprises a starting address and an ending address of the firmware in the memory, wherein a continuous storage space is formed between the starting address and the ending address.

It should be noted that, after the electronic device controller 11 writes the location information into the first register, if the value of the second register of the hard disk 12 is modified to the first preset value, the first preset value is used to instruct the hard disk controller 121 to acquire the location information in the first register, and correspondingly, when the hard disk controller 121 determines that the value of the second register is the first preset value, the location information of the firmware in the memory of the electronic device is acquired. If the hard disk 12 does not include the second register, or after the electronic device controller 11 writes the architectural location information into the first register, if the value of the second register is modified, the hard disk controller 121 may obtain the location information in real time, until the location information is obtained.

S405, the hard disk controller 121 obtains the firmware in the Memory of the electronic device in a Direct Memory Access (DMA) manner according to the location information.

The hard disk controller 121 is integrated with a DMA controller, that is, the hard disk controller 121 has the idle power of the DMA controller, and accordingly, the hard disk controller 121 may determine the location of the firmware in the memory of the electronic device according to the obtained location information, and obtain the firmware in the memory of the electronic device in a DMA manner according to the location of the firmware in the memory of the electronic device.

S406, the hard disk controller 121 stores the firmware in the memory of the hard disk 12.

After the hard disk controller 121 obtains the firmware, the firmware is stored in the memory of the hard disk 12. Optionally, after the hard disk controller 121 stores the firmware in the memory of the hard disk 12, the program instructions corresponding to the firmware may be executed to start the firmware in the hard disk 12.

According to the firmware starting method provided by the application, after the electronic device controller 11 is started each time, the electronic device controller 11 stores the latest firmware in the memory of the electronic device, and writes the position information of the firmware in the memory of the electronic device into the first register of the hard disk 12. After the hard disk 12 is powered on or reset, the hard disk controller 121 obtains the location information of the firmware in the memory of the electronic device from the first register, obtains the firmware in the memory of the electronic device according to the location information, and stores the firmware in the memory of the hard disk 12. In the present application, the firmware is not permanently stored in the storage medium of the hard disk 12, but the latest firmware is acquired in the memory of the electronic device after the hard disk 12 is powered on or reset each time, and the acquired latest firmware is directly started in the hard disk 12. Therefore, the firmware in the hard disk 12 can be ensured to be the latest firmware all the time, and further, the electronic device does not need to maintain the firmware in each hard disk 12 independently because the firmware is not stored in the hard disk 12 permanently, thereby simplifying the maintenance process of the firmware.

On the basis of any of the above embodiments, the embodiment shown in fig. 4 will be described in further detail below with reference to the embodiment shown in fig. 5.

Fig. 5 is a flowchart illustrating a second method for starting a hard disk firmware according to the present application. Referring to fig. 5, the method may include:

s501, after the electronic device controller 11 is started, the electronic device controller 11 obtains the latest firmware, and determines location information of a storage space for storing the firmware in a memory of the electronic device.

It should be noted that the execution process of S501 may refer to S401, and is not described herein again.

S502, the electronic device controller 11 stores the location information of the firmware in the memory of the electronic device in the first register of the hard disk 12.

It should be noted that the execution process of S502 may refer to S403, and is not described herein again.

S503, the electronic device controller 11 sets the value in the second register of the hard disk 12 to the first preset value.

The first preset value in the second register is used to instruct the hard disk controller 121 to obtain the location information in the first register.

Optionally, the first preset value in the second register is also used to indicate that the electronic device controller 11 has stored the location information in the first register.

After the electronic device determines that the location information is obtained, S502-S503, and S504 (storing the firmware into the memory of the electronic device) may be performed simultaneously, because the firmware is large and the process of writing data into the register is fast, when the electronic device sets the value in the second register to the first threshold value, the electronic device may not complete storing the firmware into the memory of the electronic device.

Optionally, after the hard disk 12 is powered down, the value in the second register is set to null, or a default value.

In the above process, when the first register is a nonvolatile memory, the hard disk controller 121 may be prevented from obtaining wrong location information by setting the value of the second register.

It should be further noted that S503 is an optional step, that is, the second register may not be set in the hard disk 12, and correspondingly, the first preset value may not be written in the second register after the electronic device stores the position information in the register of the hard disk 12.

And S504, the electronic equipment controller 11 stores the firmware into the memory of the electronic equipment according to the position information.

It should be noted that the execution process of S504 may refer to S401, and is not described herein again.

It should be noted that S502-S503 and S504 may be executed sequentially or simultaneously, and the execution order of S502-S503 and S504 is not specifically limited in the present application.

S505, the electronic device controller 11 sets the value in the third register of the hard disk 12 to the second preset value.

The second preset value in the third register is used to instruct the hard disk controller 121 to obtain the firmware in the memory of the electronic device in a DMA manner.

Optionally, the second preset value in the third register may also be used to indicate that the electronic device controller 11 has stored the firmware into the memory of the electronic device according to the location information.

It should be noted that S505 is an optional step, that is, the hard disk 12 may not be provided with a third register, and correspondingly, after the electronic device stores the firmware into the memory of the electronic device, the second preset value may not be written in the third register.

S506, after determining that the hard disk 12 is powered on or reset, when the value in the second register of the hard disk 12 is the first preset value, the hard disk controller 121 obtains the location information by querying the first register of the hard disk 12.

Optionally, in S506, after determining that the hard disk 12 is powered on or reset, the hard disk controller 121 may also query the first register in real time or periodically until the location information is obtained.

In the above process, when the first register is a nonvolatile memory, after the hard disk 12 is powered on or reset, the value in the first register is the value written by the hard disk 12 in the last operation process, and the location information of the firmware in the memory of the electronic device may be different in the different operation processes of the hard disk 12. When the hard disk controller 121 queries that the value in the second register is the first preset value, it may be determined that the location information in the first register is written in the hard disk 12 in the current operation process, that is, the location information in the first register is correct, so that it may be avoided that the hard disk controller 121 obtains the wrong location information.

S507, when the value in the third register of the hard disk 12 is the second preset value, the hard disk controller 121 obtains the firmware in the memory of the electronic device in a DMA manner according to the location information.

In an actual application process, after the hard disk controller 121 obtains the location information, the electronic device controller 11 may not complete storing the firmware in the memory of the electronic device, and at this time, the hard disk controller 121 may not successfully obtain the firmware in the memory of the electronic device. When the hard disk controller 121 queries that the value in the third register is the second preset value, it indicates that the firmware is stored in the memory, and at this time, the hard disk controller 121 may successfully obtain the firmware from the memory of the electronic device. In this way, the hard disk controller 121 may be prevented from performing an invalid acquisition operation in the memory of the electronic device, and further resource waste is avoided.

Optionally, in S507, after the hard disk controller 121 obtains the location information, the electronic device controller 11 may not complete storing the firmware into the memory of the electronic device, at this time, the hard disk controller 121 may obtain the firmware in the memory of the electronic device in a DMA manner according to the location information in real time or periodically until the hard disk controller 121 obtains the firmware.

For example, after the hard disk controller 121 obtains the location information, the hard disk controller 121 may obtain the firmware in the memory of the electronic device in a DMA manner according to the location information, at this time, if the firmware is not stored in the memory of the electronic device, the hard disk controller 121 cannot obtain the firmware in the memory, after a preset time period, the hard disk controller 121 obtains the firmware in the memory of the electronic device in the DMA manner according to the location information again, and the process is repeated until the hard disk controller 121 obtains the firmware in the memory of the electronic device. For example, the preset time duration may be 1 millisecond, 2 milliseconds, and the like, and in an actual application process, the preset time duration may be set according to actual needs, which is not specifically limited in this application.

S508, the hard disk controller 121 stores the firmware in the memory of the hard disk 12.

In the embodiment shown in fig. 5, after the electronic device controller 11 writes the location information into the first register, the value of the second register is set to the first preset value, and accordingly, the location information is obtained from the first register after the hard disk controller 121 inquires that the value of the second register is set to the first preset value, so that obtaining the wrong location information from the first register can be avoided. After the electronic device controller 11 stores the firmware in the memory of the electronic device, the value of the third register is set to the second preset value, and accordingly, the firmware is acquired from the memory of the electronic device only after the hard disk controller 121 queries that the value of the third register is set to the second preset value, so that the hard disk controller 121 is prevented from performing invalid acquisition operation in the memory of the electronic device, and further, resource waste is avoided.

On the basis of any of the above embodiments, optionally, the hard disk controller 121 may be divided into a plurality of modules, and different modules may perform different operations, and the modules included in the hard disk controller 121 are described in detail below with reference to fig. 6.

S702, the electronic device controller 11 stores the firmware in the memory of the electronic device.

S703, the electronic device controller 11 stores the location information of the firmware in the memory of the electronic device in the first register of the hard disk 12.

S705, the DMA module acquires the firmware in the memory of the electronic equipment according to the position information.

S706, the DMA module sends the firmware to the DFX module.

And S707, the DFX module checks the data consistency of the firmware.

Optionally, the DFX module may perform a Cyclic Redundancy Check (CRC) on the firmware to ensure the integrity and correctness of data in the firmware.

S708, after the DFX module passes the firmware verification, the firmware is sent to the firmware boot module.

S709, the firmware boot module stores the firmware in the memory of the hard disk 12.

And S710, the firmware boot module runs the program code corresponding to the firmware to start the firmware.

In the embodiment shown in fig. 7, the firmware is not permanently stored in the storage medium of the hard disk 12, but after the hard disk 12 is powered on or reset each time, the DMA module obtains the latest firmware from the memory of the electronic device, and after the DFX module verifies the firmware, the firmware boot module is responsible for starting the firmware in the hard disk 12, so that the firmware in the hard disk 12 is always the latest firmware, and further, since the firmware is not permanently stored in the hard disk 12, the electronic device does not need to separately maintain the firmware in each hard disk 12, thereby simplifying the firmware maintenance process.
