In addition, the step timing in following each method embodiments is only a kind of citing, rather than considered critical.

Fig. 1 is that a kind of hardware abstraction layer provided in an embodiment of the present invention is multiplexed schematic diagram of a scenario, as shown in fig. 1, it is assumed that It include two operating systems OS_A and OS_B based on the different basis libraries C in certain terminal device, wherein OS_A is based on basis The library C --- Libc_A exploitation, OS_B is based on the basis library C --- the A of Libc_B exploitation.Corresponding to the scene, the present invention is real The hardware abstraction layer multiplexing method of example offer is applied for realizing two operating system shown in Fig. 1 --- OS_A and OS_B is to being located at The multiplexing of the HAL of the side OS_A.

Assuming that the HAL of initial development is to distinguish with virtual HAL, it is assumed that be known as true HAL for OS_A.To make OS_B can be multiplexed the true HAL, and virtual HAL is arranged in the side OS_B.Specifically, the configuration of the API encapsulated in the virtual HAL The configuration of the API encapsulated in (being referred to as defining) and true HAL has corresponding relationship, wherein preferably, this can be set The configuration of the API encapsulated in virtual HAL is identical as the configuration of API encapsulated in true HAL, but encapsulated in the virtual HAL The realization of API is different from the realization of API encapsulated in true HAL, and the API realization encapsulated in virtual HAL is indicated by stepping into The API that the side OS_B is called is transmitted to the side OS_A by Cheng Tongxin, and the API realization encapsulated in true HAL is to actually accomplish API Calls The relevant operation information of required execution.

Wherein, configuring for the API encapsulated in virtual HAL has corresponding relationship can with the configuration of the API encapsulated in true HAL To show as one-to-one relationship, many-to-one corresponding relationship can also be shown as.As an example it is assumed that existing in true HAL Some API is configured to function (A, B, C), then API corresponding with API configuration can be in virtual HAL are as follows: function (A), function (B), function (C) form three pair one of corresponding relationship.

Wherein, since the content that API is realized in virtual HAL is related to striding course communication, therefore, it is necessary to establish as shown in figure 1 Shown in striding course communication (IPC) connection between above-mentioned two operating system: IPC Bridge, such as the IPC_A illustrated in figure, IPC_B is two end interfaces of the communication.Optionally, striding course communication can pre-establish, so as to subsequent direct use, It can establish in real time when needed.

It is to be understood that the foundation of above-mentioned striding course communication, as establishes interface IPC_A in the side OS_A, builds in the side OS_B Vertical interface IPC_B, wherein it is based on Libc_B that IPC_A, which is based on Libc_A, IPC_B,.

Optionally, striding course communication connection can be realized based on the IPC mechanism provided in operating system nucleus Kernel, Such as Socket, OpenBinder, but be not restricted to that both implementations.

In addition, the true HAL and virtual HAL in the embodiment of the present invention may be considered for some in terminal device firmly The level of abstraction of part, such as the hardware abstraction layer of camera: camera HAL；Alternatively, the hardware abstraction layer of sensor: sensor HAL, etc..

Facilities based on above-mentioned two operating system, for example, when some camera application program of the side OS_B responds In user operation and when needing to call camera HAL to operate camera, the camera application program can star one into Journey, the process may be considered process B, and process B such as calls some API in virtual camera HAL, it is assumed that the API's It configures and is accomplished by

The API is used to trigger the opening operation to camera.Wherein, bool open (int cameraId) is the API's Configuration, the realization that the content in { } is the API.CameraId is call parameters, which camera what instruction needed to operate is, than If Id=0 is front camera, Id=1 is rear camera.It is to call this API of Open, return that API_OPEN, which is indicated, Using returning the result as the return of the API result of open for ipc_send.

As can be seen that the realization of the API indicates the calling for transmitting the API to the side OS_A by striding course communication (IPC). It is communicated to which, process B can create some default process with the side OS_A in real time and be known as the striding course between process A, and passes through foundation Striding course communication will be sent to process A to the call request of the API.API Calls correlation can be carried in the call request Parameter, such as the API that needs to call are identification information --- the API_OPEN of which API, and need to open is which is taken the photograph As head --- cameraId, thus, process A can be called according to the call request corresponding A PI in true camera HAL come Complete the operation carried out needed for camera application program to camera.Assuming that configuration of the corresponding A PI in true camera HAL Be accomplished by

Wherein, open (int cameraId) is the configuration of the API, the realization that the content in { } is the API.It can see Out, the realization that is implemented among virtual camera HALs of the API in true camera HAL is different, in true camera Realization in HAL is specially the operation information etc. to corresponding hardware.

In the example above, virtual HAL is identical as the configuration of API in true HAL, is bool open (int cameraId)。

It is worth noting that above-mentioned process A is process corresponding with true camera HAL, process A can be considered as The service processes of true camera HAL, are pre-created, and process B can be considered as client process, and process A can be Start with the starting of OS_A, whether monitor always later has the client process from OA_B to need to call true camera API in HAL.

By the way that virtual HAL is arranged in OS_B, and in the virtual HAL API configuration with the configuration of true API with corresponding Relationship, for example can directly replicate the API configuration that can be formed in virtual HAL from true HAL.And in virtual HAL API realization It only needs provide the sending function of IPC and related call parameters is provided, so that virtual HAL is for true HAL, Logic is realized without complicated function, i.e., the operation of hardware is controlled without really execution, realized simple.

Below with reference to following examples, respectively with the angle of above-mentioned different operating system to provided in an embodiment of the present invention hard Part level of abstraction multiplexing method is introduced.

Fig. 2 is a kind of flow chart of hardware abstraction layer multiplexing method provided in an embodiment of the present invention, provided in this embodiment Realize have by first in the first operating system in the hardware abstraction layer multiplexing method the first operating system shown in Fig. 1 Process executes.In conjunction with Fig. 1, it is assumed that the first operating system of this in the present embodiment be OS_B, the second operating system be OS_A, first into Journey is process B, and the second process is process A.As shown in Fig. 2, this method comprises the following steps:

201, it is instructed in response to hardware operation, the first process of the first operating system calls the corresponding void of the first operating system The first application programming interfaces in quasi- hardware abstraction layer.

Optionally, in practical application, process B be can be by application program or application framework the layer starting of the side OS_B Some process, such as the process started for camera application program in the example above.Optionally, process B be also possible to The corresponding dedicated process of virtual HAL, for being called to API in virtual HAL, at this point, process B can be for applying journey Sequence accesses.

Such as: camera application program is instructed in response to the photographing operation that user triggers, and is accessed corresponding with camera virtual The corresponding process B of camera HAL transmits relevant parameter, such as camera identification camera0, and work to first process Mode --- it takes pictures.To which process B calls the API that takes pictures in virtual camera HAL based on the parameter.

202, the first process is communicated by striding course the call request of application programming interfaces being sent to the second operating system, So that the second process in the second operating system is called in the corresponding hardware abstraction layer of the second operating system according to call request Second application programming interfaces execute hardware operation instruction.

Wherein, configuration of first application programming interfaces in virtual HAL and the second application programming interfaces are in the second operation system Configuration in the i.e. true HAL of the corresponding HAL that unites has corresponding relationship.

In the present embodiment, it is assumed that above-mentioned corresponding relationship is presented as that configuration is identical, thus above-mentioned first API and the 2nd API phase Together.

As previously mentioned, process B, when calling some API, the realization based on the API will be communicated by striding course by the API Call request be sent to OS_A so that the process A in OS_A is according in the corresponding true HAL of call request calling process B The API with execute hardware operation instruction.Wherein, the content for including in the realization of the API is indicated will by striding course communication The call parameters of API are transmitted in process A, which such as includes the mark and the corresponding hardware mark of the API of the API Know.Process B can therefrom extract the call parameters, be encapsulated in call request and be sent to process A.

In practical application, process A calls process B in true HAL that the API called is needed to refer to execute above-mentioned hardware operation It enables, the readjustment that may be related to hardware operation result feeds back to process B, it is also possible to will not relate to returning for hardware operation result It adjusts.For example, above-mentioned API may realize that comparison such as inquiry subscriber terminal equipment shares several cameras, will not have at this time The readjustment of hardware operation result；For another example, above-mentioned API may be to realize that triggering camera is recorded a video, at this point, having hardware behaviour Make the readjustment of result, i.e., the video clapped camera pulls back to the first process.

Therefore, in the case of being related to hardware operation result readjustment, the hardware that process B also needs receiving process A to feed back is grasped Make result.

Optionally, which may include: hardware data, which is instructed by execution hardware operation Hardware is hardware generation corresponding with true HAL, such as above-mentioned video；Alternatively, the hardware operation result is hardware data Storage address in shared drive；Alternatively, the hardware operation result is operation failure prompt information.

Optionally, make required transmission time mistake in order to avoid needing to transmit excessive data volume between process B and process A It is long, so as to the too long holding time of true HAL and virtual HAL, influences other and need to call true HAL, virtual HAL The calling of process, process A can be directly to feed back the hardware number to process B according to the determination of the size of the data volume of hardware data According to.For example, process B is directly fed back to, conversely, by the hardware data when the data volume of the hardware data is less than preset threshold It is stored in shared drive, so that storage address of the hardware data in shared drive is only fed back to process B, so that process B The hardware data is obtained from the shared drive.Wherein, shared drive is the storage that preset two operating system can share Space.

It is worth noting that aforesaid operations failure prompt information can be considered as a kind of special hardware operation as a result, should Operation failure prompt information refers to that process A after the call request for receiving process B transmission, is called based on the call request In true HAL before corresponding API, if identifying, the API that need to be called has exclusive operational attribute, and then determines this true HAL pairs It is sent when the hardware answered is in busy condition to process B.When the hardware is in busy condition, illustrate there are other processes The true HAL is called to operate the hardware, then process A can not call the API in the true HAL at this time, thus to the first process Feedback operation failure prompt information.Wherein, it will be discussed in detail in subsequent embodiment about the explanation of above-mentioned exclusive operational attribute.

To sum up, hardware abstraction layer multiplexing method provided in an embodiment of the present invention, it is only necessary to be arranged in the first operating system side and have There is the virtual HAL of following feature, it can realize the first operating system to the corresponding real hardware level of abstraction of the second operating system Multiplexing: API configuration has corresponding relationship L in the configuration for the API being arranged in virtual HAL and true HAL, and will be in virtual HAL API realization be set as by striding course communicate the calling of some API in virtual HAL will be transmitted to corresponding to true HAL's In second operating system.The program, it is convenient to realize, and can be adapted for any different operating system.

Fig. 3 is the flow chart of another hardware abstraction layer multiplexing method provided in an embodiment of the present invention, the present embodiment provides The hardware abstraction layer multiplexing method executed by the first process in the first operating system.Assuming that first in the present embodiment grasps It is OS_A shown in FIG. 1 as system, the second operating system is OS_B shown in FIG. 1, and the first process is process A shown in FIG. 1, the Two processes are process B shown in FIG. 1, thus, as shown in figure 3, this method may include steps of:

301, the first process receives the call request that the second process is sent by striding course communication in the second operating system, adjusts It is that the second process is instructed in response to hardware operation and in the corresponding virtual hardware level of abstraction of the second operating system of calling with request The triggering of first application programming interfaces.

302, the first process calls the second application in the corresponding hardware abstraction layer of the first operating system according to call request Routine interface, to execute hardware operation instruction.

Wherein, configuration of first application programming interfaces in virtual HAL and the second application programming interfaces are in the first operation system Configuration in the corresponding hardware abstraction layer, that is, true HAL of system OS_A has corresponding relationship.

In the present embodiment, it is assumed that above-mentioned corresponding relationship be presented as configuration of first application programming interfaces in virtual HAL with Configuration of second application programming interfaces in true HAL is identical, is illustrated below based on the hypothesis.

Wherein, the mark for the API that process B to be called can be carried in above-mentioned call request and that needs operate is hard The information such as the mark of part, so that process A can call corresponding API in true HAL accordingly.

Process A can be a process for being set in advance in the side OS_A, exist in OS_A starting.Process A is responsible for Process in OS_B is to the calling of true HAL corresponding to OS_A, so that OS_B can be multiplexed the true HAL of the side OS_A.

The detailed process that process A executes above-mentioned steps may refer to the related description in previous embodiment, and this will not be repeated here.

Fig. 4 is the flow chart of another hardware abstraction layer multiplexing method provided in an embodiment of the present invention, is implemented with shown in Fig. 3 Example is the same, and the hardware abstraction layer multiplexing method provided in this embodiment can be held by the first process in the first operating system Row.Assuming that the first operating system in the present embodiment is OS_A shown in FIG. 1, the second operating system is OS_B shown in FIG. 1, the One process is process A shown in FIG. 1, and the second process is process B shown in FIG. 1, thus, as shown in figure 4, this method may include Following steps:

401, the first process receives the call request that the second process is sent by striding course communication in the second operating system, adjusts It is that the second process is instructed in response to hardware operation and in the corresponding virtual hardware level of abstraction of the second operating system of calling with request The triggering of first application programming interfaces.

402, the first process needs to call in the corresponding hardware abstraction layer of the first operating system according to call request determination Second application programming interfaces, if identifying, the second application programming interfaces have exclusive operational attribute, check hardware abstraction layer pair The state for the hardware answered.

If 403, the state of hardware indicates that hardware is in idle condition, the first process calls the first behaviour according to call request Make the second application programming interfaces in the corresponding hardware abstraction layer of system, to execute hardware operation instruction.

404, the state of hardware is set to busy condition by the first process.

If 405, hardware execute hardware operation instruction and generate hardware data data volume be less than preset threshold, first Hardware data is sent to the second process by process；If the data volume of hardware data is greater than or equal to preset threshold, the first process Hardware data is stored in shared drive, and storage address of the hardware data in shared drive is sent to the second process.

The mark for the first API that process B is called in virtual HAL can be carried in the call request sent by process B Know, thus, process A can configure the corresponding relationship seen with API in virtual HAL based on API configuration in true HAL, determine true Twoth API corresponding with the first API of calling needed for process B in real HAL.

In an alternative embodiment, process A can be called immediately in true HAL after receiving above-mentioned call request Corresponding 2nd API.But in some practical application scenes, when process A needs to call the 2nd API in true HAL to come When carrying out certain operation to hardware corresponding to the true HAL, this is had called up before possible other processes there are also in OS_A Some API in true HAL operates the hardware.And if the hardware only can be by a process in the same time Operation, i.e., if the hardware belongs to exclusive hardware, should not allow process A to call the API in true HAL at this time.Citing comes It says, it is assumed that some process is controlling camera and carrying out photographing operation, then another process cannot use the camera simultaneously ?.

Therefore, in order to avoid calling while different processes are to same true HAL, that is, avoid different processes to same hardware While from operation, process A additionally provides mutual exclusion mechanism, the mutual exclusion mechanism in simple terms be exactly when true HAL currently by some When process is called, the state of hardware corresponding to the true HAL can be set to busy condition by process A, otherwise be set to idle state, with Calling while multiple processes are avoided to the true HAL.Wherein, which refers to that the hardware is occupied by some process, because This, which also refers to occupied state, and correspondingly, idle state can also refer to unoccupied state.

To realize that above-mentioned mutual exclusion function, process A call second in true HAL in the call request based on process B Before API, it can first identify whether the 2nd API has exclusive operational attribute, the 2nd API has exclusive operation if identifying Attribute then checks the state of hardware corresponding to true HAL, if the state of the hardware indicates that the hardware is in idle condition, Process A can call the 2nd API in true HAL to instruct to execute hardware operation according to the call request of process B at this time；And if The state of the hardware indicates that the hardware is in busy condition, then process A then sends operation failure prompt information to process A, at this time Illustrate the hardware just by other process operations.On the contrary, if identifying, the 2nd API does not have exclusive operational attribute, illustrates Even if having other processes calling true HAL at this time to operate the hardware, the execution for the 2nd API that process A is called is not yet Being normally carried out for other processes is influenced whether, at this point, process A can also call the 2nd API in true HAL to grasp to execute hardware It instructs.

In the present embodiment, the exclusive operational attribute of above-mentioned 2nd API is referred to as EXCEPT operation attribute, and meaning can To understand are as follows: if allow different processes while the 2nd API being called to carry out certain operation to hardware, the 2nd API does not have There is exclusive operational attribute, on the contrary, if do not allow different processes while the 2nd API being called to carry out certain operation to hardware, Then the 2nd API has exclusive operational attribute.As an example it is assumed that the 2nd API can be realized the opening operation to camera, Then since actually some process has been switched on camera in the case where, do not allow another process to be again turned on camera, so There is exclusive operational attribute for realizing the 2nd API of camera open function.For another example, it is assumed that the 2nd API is for real The query function for the camera number for including in existing terminal device, then due to being actually that can permit multiple processes while inquiring Camera number, so the 2nd API does not have exclusive operational attribute.

It is alternatively possible to identify whether the 2nd API has exclusive behaviour according to the configuration of the 2nd API in true HAL Make attribute.For example, can in the 2nd API with centering certain field, the different values of the field for indicate this Whether two API have exclusive operational attribute, for example 00 indicates do not have exclusive operational attribute, and 01 indicates that there is exclusive operation to belong to Property.

In an alternative embodiment, process A can be after the call request for often receiving process B transmission, if identifying this Call request API corresponding in true HAL has exclusive operational attribute, then carries out the inquiry of hardware state immediately.But In another alternative embodiment, process A can also only be certain spy with exclusive operational attribute recognize the need for calling When determining API, the state of hardware is just checked, to reduce inquiry operation.Therefore, process A is in the call request for receiving process B transmission Afterwards, if identifying, the call request the 2nd API corresponding in true HAL has exclusive operational attribute, and the 2nd API It is just to check the state of the hardware at this time for realizing the opening operation to hardware.For by taking camera is applied as an example, generally Ground, during being taken pictures by camera, process B may need successively to call open camera, open preview, take pictures, Close these API of camera.When process B calls the API for opening camera in virtual HAL, process A can receive process B The corresponding call request of API of the unlatching camera sent, in turn, process A identify the API have exclusive operational attribute and For realizing the opening operation of camera, then the state of camera is inquired, it is assumed that camera is in idle condition at this time, then process A calls the corresponding API for opening camera in true HAL to execute opening operation to camera, and the state of camera is set to Busy condition, at this point, optionally, it is process B that process A, which also can recorde the lower process that camera is set to busy condition,.Later, Optionally, process A is opened to process B feedback and is successfully indicated, thus, process B continues to call the API that preview is opened in virtual HAL. At this point, process A is after the corresponding call request of API for receiving the unlatching preview, even if identifying that the unlatching is pre- in true HAL The API look at has exclusive operational attribute, can also be without the inquiry of camera state, because process B also and is not finished to taking the photograph As the operation of head.Until process A receive process B to close camera API call request, identify the closing camera API there is exclusive operational attribute, and for realizing the shutoff operation to camera, at this point, process A sets the state of camera For idle state, process B terminates the operation of camera at this time.

Therefore, if process A identifies that the 2nd API has exclusive operational attribute, and the 2nd API is for realizing to hardware The state of hardware is then set to idle state by shutoff operation.In addition, in practical application, to the calling of true HAL, in addition to existing Process A needs to call outside the situation of true HAL, it is also possible to which there are some processes of the side OS_A application program launching, it is assumed that claims Need to call the situation of true HAL for third process.At this point, third process before calling true HAL, needs to inquire to process A The state of the corresponding hardware of the true HAL, to be called when the hardware is in idle condition to true HAL.Therefore, process A can also receive the state for being used to inquire the corresponding hardware of true HAL that third process is sent by striding course communication in OS_A Inquiry request, and the state of hardware is sent to third process so that third process determine whether to call according to the state it is true Real HAL.

As in the preceding embodiment, in order to avoid the too long holding time to true HAL, process A can be according to calling 2nd API and when executing hardware operation instruction the data volume size determination of hardware data caused by hardware be directly by the hardware Data feedback gives process B, or storage address of the hardware data in shared drive is fed back to process B.

To sum up, process A is provided in the side OS_A with true HAL, to monitor asking to the calling of true HAL from OS_B It asks, to assist completing multiplexing of the OS_B to true HAL；In addition, process A also provides mutual exclusion mechanism, to avoid multiple processes pair It is called while the true HAL corresponding to exclusive hardware.
