[0039] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] The embodiment of the present application provides a method for updating the firmware of a device to be updated, the method is applied to an electronic device, the electronic device includes a plurality of sub-devices; Figure 1 As shown, the method includes:

[0041] S101: Obtain a firmware update instruction for an electronic device.

[0042] In this step, the electronic device includes a laptop computer, a desktop computer, etc. The electronic device includes multiple sub-devices. Taking the electronic device as a laptop computer as an example, the sub-devices of the electronic device include a battery, a touchpad, a camera, etc. The firmware update instruction is a firmware update instruction triggered by a user for the electronic device.

[0043] S102: Based on the update instruction, determine a device to be updated among a plurality of sub-devices of the electronic device.

[0044] In this step, the firmware update instruction can indicate which sub-devices the user intends to update. Based on the firmware update instruction triggered by the user, the device to be updated among multiple sub-devices of the electronic device can be determined. The number of devices to be updated can be one or more.

[0045] S103: Acquire an update data packet for the device to be updated; the update data packet includes the firmware information to be updated of the device to be updated and a first driver; the first driver is used to flash the firmware information to be updated.

[0046] After the device to be updated is determined in the aforementioned step S102, an update data packet Capsule for the device to be updated is obtained. It can be understood that the update data packet of the device to be updated is the downloaded update package of the device to be updated, which includes the firmware information to be updated Firmware Binary and the first driver FMP Driver (Firmware Management Protocol Driver). The first driver is used to flash the firmware information to be updated, thereby realizing the update of the device to be updated. Figure 2 As shown, Figure 2 The update data packets of three devices to be updated (battery, camera, touchpad) are shown, among which the update data packet of the battery (Battery) is a Battery Capsule, which includes the firmware information to be updated of the battery (Battery Firmware Binary) and the first driver (Battery FMPDriver). The update data packet of the camera (Camera) is a Camera Capsule, which includes the firmware information to be updated of the camera (Camera Firmware Binary) and the first driver (Camera FMP Driver). The update data packet of the touchpad (TouchPad) is a TouchPad Capsule, which includes the firmware information to be updated of the touchpad (TouchPad Firmware Binary) and the first driver (TouchPad FMP Driver).

[0047] S104: Update the device to be updated based on the firmware information to be updated and the first driver.

[0048] In this step, after obtaining the update data packet for the device to be updated, the first driver in the update data packet is used to flash the firmware information to be updated, so as to realize the update of the device to be updated. By storing the first driver for flashing the firmware information to be updated in an update data packet independent of the BIOS of the electronic device, the embodiment of the present application can not only effectively save the space of the BIOS, but also realize the dynamic update of the sub-devices of the electronic device by only loading the first driver of the device to be updated, compared with the solution of the related art that the first drivers of all devices are stored in the BIOS in advance. At the same time, if there is a problem with the update driver during the development process, it is only necessary to re-verify the separate update data packet to which the problem driver belongs, without the need to recompile and verify the entire BIOS, thereby improving the development and maintenance efficiency.

[0049] In the scheme shown in steps S101 to S104, a firmware update instruction for an electronic device is obtained; based on the update instruction, a device to be updated among multiple sub-devices of the electronic device is determined; an update data packet for the device to be updated is obtained; the update data packet includes the firmware information to be updated of the device to be updated and a first driver; the first driver is used to flash the firmware information to be updated; based on the firmware information to be updated and the first driver, the device to be updated is updated. It can save space in the BIOS of an electronic device and reduce product costs. At the same time, it can provide other key functions in the future (such as Figure 2 The FV2 and FV1 areas in the RAID controller card are reserved to improve product scalability. When a problem occurs in the driver update, only the corresponding update data package needs to be updated and modified, which improves the efficiency of electronic equipment development and maintenance.

[0050] In an optional solution, the electronic device includes a basic input and output system BIOS, and the BIOS stores a second driver program; and determining a device to be updated among a plurality of sub-devices of the electronic device based on the update instruction includes:

[0051] Based on the second driver, generating a sub-device information table of the electronic device;

[0052] Based on the update instruction and the sub-device information table of the electronic device, a device to be updated among the multiple sub-devices of the electronic device is determined.

[0053] In this application, reference Figure 2As shown, the BIOS of the electronic device, specifically the ROM (Read-Only Memory) of the BIOS, stores a second driver ESRT Driver. The second driver is used to generate a sub-device information table ESRT table of the electronic device. The sub-device information table ESRT table includes relevant information of all sub-devices of the electronic device, including the model, version number, etc. of the sub-device. The sub-device information table ESRT table is used to identify each sub-device and its corresponding firmware resources, so as to achieve the purpose of pushing the corresponding firmware resources to be updated for the corresponding sub-device (device to be updated). Specifically, the sub-device information table ESRT table of the electronic device is generated based on the second driver ESRT Driver. According to the acquired firmware update instruction, the corresponding sub-device is found and located in the sub-device information table ESRT table of the electronic device, and it is subsequently updated as a device to be updated.

[0054] In an optional solution, the BIOS further stores a third driver, and the third driver is used to load the first driver; and updating the device to be updated based on the firmware information to be updated and the first driver includes:

[0055] The device to be updated is updated based on the firmware information to be updated, the first driver and the third driver.

[0056] In this application, reference Figure 2 As shown, a third driver Launch Driver is also stored in the BIOS. The third driver is used to load the first driver. Specifically, the third driver loads the first driver, and the first driver flashes the firmware information to be updated, thereby updating the device to be updated. This is simple and easy to implement, and can improve the efficiency of updating the device to be updated.

[0057] Among them, the key functions involved in updating the device to be updated are abstracted as follows:

[0058] 1) UEFI (Unified Extensible Firmware Interface) dynamic loading algorithm:

[0059] A) Conditional function of dynamic loading scheme: R(c)

[0060] B) Dynamically loaded function: A(c, e)

[0061] C) Dynamic execution judgment:

[0062] 2) Sub-device maintenance queue and event pool

[0063] A) Sub-device type information maintenance queue: C = {c1, c2, ..., cn}

[0064] B) Sub-device information creation related processing events: E = {e1, e2, ..., em}

[0065] C) Sub-device information creation: D(C)→E

[0066] 3) Safety verification

[0067] A) Security verification function: D f (a)

[0068] B) Security verification processing: D f (a) → exception

[0069] 4)UEFI firmware flashing algorithm

[0070] A) Conditional function for firmware flashing: P(c)

[0071] B) Firmware flashing function: U(c, e)

[0072] C) Firmware flash execution judgment:

[0073] 5) System abnormality check

[0074] A) System abnormality check function: L f (u)

[0075] B) Abnormal verification processing: L f (u)→exception

[0076] 6)Integrate control flow algorithms

[0077]

[0078] Here, (R(c)→A(c, e)) means that if the condition (R(c)) is true, the dynamic loading process (A(c, e)) is executed.

[0079] (C) and (E) represent the sub-device type information queue and information creation related processing event pool respectively.

[0080] (D(C)→E) indicates that the sub-device information queue maintenance (D(C)) triggers the events in the event pool (E).

[0081] It means that for all actions (a), if the safety verification function (D f (a)) If the function returns true, the exception is handled and the operation is exited.

[0082] (P(c)→U(c, e)) means that if the condition (P(c)) is true, the firmware flashing action (U(c, e)) is executed.

[0083] Indicates that for all actions (u), if the system abnormality check function (L f (u)) returns true, then exception handling is performed and the operation is exited.

[0084] In an optional solution, the update data packet further includes a fourth driver, and the fourth driver is used to load the first driver; and updating the device to be updated based on the firmware information to be updated and the first driver includes:

[0085] The device to be updated is updated based on the firmware information to be updated, the first driver and the fourth driver.

[0086] In this application, the update data package also includes a fourth driver. It should be noted that the fourth driver is the same driver as the aforementioned third driver, both are Launch Drivers, and both are used to load the first driver. The difference is that the third driver is stored in the BIOS, while the fourth driver is stored in an update data package of the device to be updated that is independent of the BIOS. Figure 2 As shown, Figure 2 The portion surrounded by the dashed line is the Launch Driver, which can be stored in one of the BIOS and each update data package. That is to say, in the embodiment of the present application, the driver (third / fourth driver) used to load the first driver can be stored in the BIOS, or can be stored separately in the update data package of each device to be updated. The setting is flexible and can be customized according to different actual needs, with strong flexibility and scalability.

[0087] In an optional solution, the update data packet further includes header data; before updating the device to be updated based on the firmware information to be updated and the first driver, the method further includes:

[0088] Filtering the header data in the update data packet to obtain a filtered update data packet;

[0089] The firmware information to be updated and the first driver program in the filtered update data packet are obtained.

[0090] In this application, reference Figure 2As shown, the update data packet also includes header data EFI_CAPSULE_HEADER, which contains metadata information of the firmware update, such as the firmware version number, the firmware image size, etc. Before updating the device to be updated, it is necessary to remove (filter) the header data in the update data packet, and extract the firmware information to be updated and the first driver in the data packet. Redundant data can be removed before flashing the firmware information to be updated, so as to achieve a more accurate firmware update.

[0091] In an optional solution, the number of the devices to be updated is one or more; and the number of update data packets of each of the devices to be updated is one or more.

[0092] In this application, considering that the user may need to update multiple sub-devices at one time, the number of devices to be updated may be one or more. For each sub-device, since there may be multiple models of materials for the same sub-device in the electronic device (such as two batteries placed in the electronic device, the models of the two batteries are different), one model of sub-device corresponds to one update data packet, and the update data packet of the device to be updated may be one or more.

[0093] The embodiment of the present application also provides an updating device for device firmware to be updated, the device is applied to an electronic device, the electronic device includes a plurality of sub-devices; Figure 3 As shown, the device comprises:

[0094] A first acquisition unit 301 is used to acquire a firmware update instruction for an electronic device;
