Based on the description of the core idea above to the application control method, and combine above to virtual unit and its equipment
The description of the creation process of file, present applicant proposes a kind of refinement schemes to the control method, referring to shown in Fig. 3 another
The flow diagram of kind control method, this method may include but be not limited to following steps:
Step S31, between application run-time in a reservoir, obtain this using virtual unit device file；
Step S32, inquires whether the virtual unit is mapped with external equipment, if not, entering step S33；If so, holding
Row step S35；
In the present embodiment, in the application of virtual unit operation, it is able to access that the external equipment of virtual unit mapping,
In practical application, virtual unit is created for some container, but multiple containers can share same external equipment, institute
With virtual unit usually corresponds to unique container, but can map multiple external equipments, so that operating in the virtual unit
Using the multiple external equipments of the person of being able to use.
In order to improve the reliability using external equipment, the application in deployment Mr. Yu's container needs to set using outside
In the case where standby, if device drives obtain the equipment access request of the application, the corresponding virtual unit of the container can be first checked
Currently whether it is mapped with true external equipment.
Step S33 obtains the external equipment for being currently at idle state；
External equipment it is not mapped with currently in the virtual unit of application operation (i.e. application needs external equipment to be used)
In the case of, it can detecte the state of each external equipment in computer system, determining needs external equipment type to be used with application
It is identical, and it is currently at the external equipment of idle state.
Wherein, the idle state of external equipment can refer to it not by any using in this case, this is in sky
The external equipment of not busy state can not establish mapping relations with any virtual unit, even if having with the external equipment foundation reflect
The resource etc. of the external equipment is currently not used in the application penetrating the virtual unit of relationship, but operating in the virtual unit.
Certainly, the idle state of external equipment can also refer to the external equipment by least one using but its resource
Still there is allowance, i.e., can also receive the access request of new application.In this case, which, which is usually mapped with, virtually sets
Application that is standby, but being currently operating in these virtual units of mapping, and all resources of the vacant external equipment, residue money
Source can also support other application to run.
It can be seen that the application can be accounted for by the mapping relations of detection external equipment and/or the resource of the external equipment
With situation etc., to determine whether the external equipment is in idle condition, but it is not limited to the detection method of the present embodiment description.
Step S34 establishes the mapping relations between the virtual unit and the external equipment being currently in idle condition；
The application to the construction methods of the mapping relations between virtual unit and external equipment without limitation, usual situation
Under, after the mapping relations for determining virtual unit and external equipment, which can be stored to corresponding virtual unit and
In external equipment, so that the application in virtual unit can be able to carry out data interaction, but not office between the external equipment
It is limited to this.
The external equipment that the virtual unit currently maps is written in equipment operation context by step S35；
In conjunction with above description, external equipment is configured with the device memory for storing equipment operation context, sets in outside
For when being first used, the equipment that device drives can be created runs context, be written in the device memory of the external equipment,
To complete the initial configuration to the external equipment, so that the external equipment can work normally.
Step S36 sends state to the external equipment and restores order, so that external-device response equipment operation is up and down
Text realizes the data interaction with application.
In the present embodiment, the interface that external equipment restores order and state save command by being configured to reception state is posted
Storage, so that state saving/restoring command interface is externally transparent, so, the device drives of computer equipment can be by calling shape
State saving/restoring command interface sends state to the interface register and restores order, so that the external equipment is read in equipment
Equipment in depositing runs context, and responds equipment operation context, initial configuration is completed, so that using can be normal
Operate the external equipment, meet application demand, as the external equipment can receive and response application send operational order, and
Feedback operation data are applied to this, that is, realize the data interaction between the external equipment and application.
Wherein, the data exchange process about application and external equipment, the application are not detailed, can specifically answer according to this
It is determined with the factors such as type and its demand of current operation phase, so, for different types of application, in different operation ranks
Section, may be different from the data exchange process of external equipment, and the application does not do and is described in detail one by one.
Optionally, in practical applications, for realizing application and certain external equipment according to foregoing embodiments describing mode
After data interaction, after a period of time, the application may not need temporarily using the external equipment, in order to avoid setting outside this
The waste of standby resource, can discharge the external equipment, so that other application is able to use the external equipment.Specifically discharged
Journey is referred to the signaling process figure of the another embodiment of control method shown in Fig. 4, when this method is mainly long to certain external equipment
Between be illustrated by the control flow in the case where application access, as shown in figure 4, this method may include but be not limited to
Lower step:
Step S41, device drives determine that external equipment not by application access, is sent out within a preset period of time to the external equipment
Send state save command；
Wherein, preset time period can be a longer continuous time period, the application to its specific value without limitation.
In practical applications, certain external equipment the case where being not used by for a long time can there are many kinds of, as set outside this
Standby not map any virtual unit, no application is able to use the external equipment；Alternatively, the external equipment is mapped with virtual unit,
But the application for operating in the virtual unit does not need to use outside other of virtual unit mapping using the external equipment
Equipment leads to external equipment situations such as being not used by for a long time, and the application is to external equipment in the tool being not used by for a long time
Body situation is without limitation.
In order to avoid the waste to external device resource, in the case where determining that certain external equipment is not used by for a long time,
The external equipment can be discharged, before this, driving equipment is needed to record the current equipment operation context of the external equipment, with
When just using the external equipment next time, the external equipment can be controlled and be directly returned to current state.
Based on this, the present embodiment can be by calling the state saving interface of the external equipment, to connecing for the external equipment
Mouth register sends state save command, but the sending method of the state save command is not limited to a kind of this implementation.
Step S42, external-device response state save command save current device and run context；
Step S43, external equipment save prompt information to device drives feedback states；
External equipment receives device drives will be after gas saves the order of state, can be by the configuration of current device and interior
Some key state data in portion, the i.e. current device of the external equipment run context, the equipment for being synchronized to the external equipment
Memory saves, and the application runs context data content without limitation to the current device of external equipment, can be based on outside this
The type and its working condition of equipment determine, and are key state for which status information of the external equipment that needs save
Information, can also the factors setting such as type based on the external equipment and its working principle different external equipments are needed
The key state data content of preservation is often different, the application to it without limitation.
In practical applications, after the determining operation context write device memory by its current device of external equipment, Ke Yigao
Know device drives, if what the present embodiment proposed saves prompt information to device drives feedback states, being used to annunciator driving should
External equipment is to current device operation context backup storage.The application saves the content of prompt information and its defeated to the state
Form etc. is without limitation out.
Step S44, the current device that the synchronous storage external equipment of device drives saves run context；
After device drives learn that current device is run context write device memory by external equipment, can directly it be set from this
Standby memory reads the current operation context of the equipment, and is synchronized to driver, in this way, device drives determine the external equipment
Again by use, the above-mentioned current device saved at this time can be run context is written the external equipment, so that this is outer
Portion's equipment can be directly returned to state when last terminate using the external equipment.
Step S45, device drives discharge the mapping relations of the external equipment and virtual unit, and working as the external equipment
Preceding state is adjusted to idle state.
After analysis above, device drives determine that the external equipment is not used by for a long time, it is believed that respectively apply current rank
Section is not needed using the external equipment, can directly discharge the mapping relations between the external equipment and virtual unit, and should
The current state of external equipment is adjusted to idle state, that is to say, that can mark the external equipment being not used by for a long time
