Docking stations, also referred to as port replicators, have various ports for connecting to different peripheral devices such as a keyboard, mouse, audio/video output, storage device, or the like. Each port may have a separate function (e.g., audio, video, power, and the like). When a computing device is docked with the docking station, the ports can be provided as if the peripheral devices were the part of the computing device. Thus, the computing device can be allowed to connect with various peripheral devices than would be possible using the ports on the computing device.
Examples are described in the following detailed description and in reference to the drawings, in which:
Many computing devices may have ports to connect to and interface with peripheral devices. Such ports may implement the universal serial bus (USB) standard. The physical interface specifications of the USB standard may allow for a variety of peripheral devices to be connected to a computing device using a simple and standardized socket. Example peripheral devices may include external hard drives, displays, monitors, mice, keyboards, wireless network adapters, scanners, printers, and the like.
However, the peripheral devices can also be connected to the computing device via a docking station. The docking station may provide the computing device with a “one stop” quick connection to the peripheral devices that are included in the docking station. In other words, the docking station may be used to extend an input/output (IO) port array of the computing device and provide a means for the computing device to hook up to a variety of peripheral devices. The docking station may be connected to the computing device, for instance, by a USB interface or a wireless interface. The peripheral devices may be connected to the docking station via a corresponding peripheral port, a wireless interface, or a combination thereof. Example peripheral ports may include a display port, USB-C port, USB-A port, video graphics array (VGA) port, network interface card (NIC), earphone, audio module, and the like.
Further, the docking station may include various components (e.g., integrated circuits (ICs)) that serve to operatively connect the computing device to the peripheral devices when the computing device is plugged into the docking station. In some examples, the docking station may include multiple components from different vendors integrated together. Example components may include Microcontroller unit (MCU), a dual USB type-C controller, an audio codec, a local area network (LAN) controller, a Universal Serial Bus (USB) hub controller, a USB power delivery (PD) controller, and the like to support and control various peripheral ports or interfaces of the docking station. Further, the docking station may include multiple firmware to support such components. The firmware upgrade process supported by each component vendor or IC manufacturer may be different.
Some example methods for docking firmware update may facilitate one-click firmware upgrades to multiple components from different vendors. However, the docking firmware update may follow a serial sequence (e.g., update one component after other) to update firmware for the components of the docking station, thereby consuming a significant amount of time to complete the docking firmware update for the components.
Examples described herein may determine components of a docking station, for which the firmware can be updated in parallel. In one example, the components for which the firmware can be updated in parallel may be determined based on dependency relationship between the components. Further, examples described herein may perform firmware update of the components of the docking station in parallel. Thus, examples described herein may enable parallelization of the firmware update for the components of the docking station to reduce overall time for completing the firmware update, process.
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present techniques. It will be apparent, however, to one skilled in the art that the present apparatus, devices and systems may be practiced without these specific details. Reference in the specification to “an example” or similar language means that a particular feature, structure, or characteristic described is included in that one example, but not necessarily in other examples.
Turning now to the figures,
Further, example computing device 100 may include a processor 102 and a memory 104 in communication with processor 102. Memory 104 may include firmware update logic 106 executable by processor 102 to update first component firmware 110 in parallel with second component firmware 112 on external device 108.
Firmware update logic 106 may be implemented in hardware, machine-readable instructions, or a combination thereof. Firmware update logic 106 may be implemented as engines or modules comprising any combination of hardware and programming to implement the functionalities described herein. In other examples, firmware update logic 106 care be implemented with a microcontroller, an application-specific integrated circuit (ASIC), a programmable gate array (PGA) or any other type of hardware component.
During operation, firmware update logic 106 may detect external device 108 connected to computing device 100. When computing device 100 is docked with external device 108, for instance via a wired interface or a wireless interface, firmware update logic 106 may detect a connection between external device 108 and computing device 100.
Further, firmware update logic 106 may determine that first component firmware 110 and second component firmware 112 on external device 108 may have to be updated. Furthermore, firmware update logic 106 may determine components, for which the firmware can be updated in parallel. Then, firmware update logic 106 may perform the update of first component firmware 110 in parallel with the update of second, component firmware 112 on external device 108.
Further, computing device 100 may include a user interface 152. User interface 152 may be rendered on a display of computing device 100. Example display may include liquid crystal display (LCD), light emitting diode (LED) display, electro-luminescent (EL) display, or the like. In one example, firmware update logic 106 may generate a notification 154 on user interface 152 of computing device 100. Notification 154 may include an option to update first component firmware 110 and second component firmware 112. Example option may include a first option to perform the firmware update and a second option to postpone the firmware update. Further, firmware update logic 106 may perform the update of first component firmware 110 in parallel with the update of second component firmware 112 in response to a selection of the option.
In another example, firmware update logic 106 may perform the update of first component firmware 110 in parallel with the update of second component firmware 112 on external device 108 without user interaction when external device 108 is connected to computing device 100. In this example, external device 108 may have to be connected to computing device 100 when firmware update logic 106 is executed and may have to, stay connected till the completion of update of first component firmware 110 and second component firmware 112. Thus, firmware update logic 106 may run silently, loud, or non-interactively, which may show update status in UI 152, but may not require any action from the user.
In other examples, firmware update logic 106 may first download first component firmware 110 and second component firmware 112 to computing device 100 via a network, and then perform the update of first component firmware 110 in parallel with the update of second component firmware 112 on external device 108 when external device 108 is connected to computing device 100.
Thus, firmware update logic 106 may enable to deploy firmware updates to external device 108 that may or may not be connected to computing device 100 at the time of installation of the package. When a supported docking station (i.e., external device 108) is connected and the user is logged onto computing device 100, firmware update logic 106 may determine whether a firmware is to be updated. When the firmware is to be updated, UI 152 may be displayed for user consent for the firmware update. Upon user consent, update of first component firmware 110 and second component firmware 112 may be performed on external device 108 in parallel.
In one example, memory ay include a detection logic 206, a dependency determination logic 208, and firmware update logic 210 that are communicative with each other to perform the first firmware update and the second firmware update in parallel. Detection logic 206, dependency determination logic 208, and firmware update logic 210 may be implemented in hardware, machine-readable instructions, or a combination thereof. Detection logic 206, dependency determination logic 208, and firmware update logic 210 may be implemented as engines or modules comprising any combination of hardware and programming to implement the functionalities described herein. For example, detection logic 206, dependency determination logic 208, and firmware update logic 210 can be implemented with a microcontroller, an application-specific integrated circuit (ASIC), a programmable gate array (PGA), or any other type of hardware component.
During operation, detection logic 206 can be executable by processor 202 to detect an external device 212 connected to computing device 200. Example external device 212 may be a docking station. Further, external device 212 may include various components such as first component 214, second component 216, a third component and the like. The components may refer to ICs that serve to operatively connect computing device 200 to various peripheral devices when computing device 200 is plugged into the docking station.
Further, dependency determination logic 208 can be executable by processor 202 to determine a dependency relationship between first component 214 and second component 216 of external device 212. In one example, dependency determination logic 208 may be executable by processor 202 to retrieve a component tree structure including the dependency relationship between first component 214 and second component 216 of external device 212. Example component tree structure may include leaf components that may have no dependencies and components at a higher level that have dependencies. Further, dependency determination logic 208 may determine the dependency relationship between first component 214 and second component 216 based on analyzing the component tree structure. An example component tree structure is shown in FIG.
Furthermore, firmware update logic 210 can be executable by processor 202 to perform a first firmware update of first component 214 in parallel with a second firmware update of second component 216 based on the dependency relationship. In one example, firmware update logic 210 may be executable by processor 202 to perform the first firmware update in parallel with the second firmware update when first component 214 does not have dependency relationship with second component 216.
In some examples, firmware update logic 210 may be executable by processor 202 to perform the first firmware update of first component 214 in parallel with the second firmware update of second component 216 of external device 212 at a first level. Further, firmware update logic 210 may be executable by processor 202 to perform a third firmware update associated with a third component of external device 212 at a second level upon successfully completing the first firmware update and the second firmware update. In this example, the second level may be a higher level than the first level in the component tree structure and the third component may have a dependency relationship with first component 214 or second component 216. An example firmware update process may be explained in
As shown in
For example, dual USB Type-C controller 302 may comply with USB Type-C and power delivery (PD) standards and also provide a complete dual USB Type-C and USB-power delivery port control solution for computing device 200, external device 212, and the peripheral devices. USB hub controllers 304 and 306 may support respective USB ports and perform respective operations such as controlling charging of peripheral devices through USB ports. USB hub controllers 304 and 306 may be associated with different IC manufacturers. LAN controller 308 may support an Ethernet port or a LAN port and control Ethernet communications between computing device 200, external device 212, and the peripheral devices. Audio codec 310 may support audio ports to encode analog audio as digital signals and decodes digital back into analog. Similarly, external device 212 may include various other components, each having a respective function. Further, external device 212 may include multiple firmware to support components 302-312.
Further,
Therefore, dependency determination logic 208 may determine the component firmware update sequence and firmware update logic 210 may execute the determined sequence for component tree structure 314 as follows:
Computing device 100 of

Instructions 408 may be executed by processor 402 to determine that a first component firmware and a second component firmware associated with a first component and a second component, respectively, of the external device are to be updated.
Instructions 410 may be executed by processor 402 to determine a dependency relationship between the first component and the second component of the external device. In one example, instructions to determine the dependency relationship between the first component and the second component may include instructions to retrieve a component tree structure including a dependency relationship between a plurality of components including the first component and the second component and determine the dependency relationship between the first component and the second component based on analyzing the component tree structure.
Instructions 412 may be executed by processor 402 to perform an update of the first component firmware of the first component in parallel with an update of the second component firmware of the second component at a first level when the first component does not have the dependency relationship with the second component.
Further, machine-readable storage medium 404 may store instructions to update the first component firmware of the first component in, sequence with the second component firmware of the second component when the first component has the dependency relationship with the second component.
Furthermore, machine-readable storage medium 404 may store instructions to update a third component firmware associated with a third component of the external device at a second level upon successfully completing the update of the first component firmware and the second component firmware. The third component may have a dependency relationship with the first component or the second component.
