Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figure 1, common server enters or releases the basic principle of silent status in the prior art.MCPU
Middle there are a QA (Quiescence Arbiter, i.e., silent resolvers), and (cache agent, that is, cache one CA of association
Agency).It is well known that CA is associated with CPU, CPU realizes Outside Access by CA.It will be known as superfine with the associated CA of MCPU herein
CA, to guarantee that the function of MCPU is realized, the superfine CA needs remain transmission-receiving function.And so-called silent status,
It can be understood that stopping Outside Access to be that all CA except superfine CA is made to empty external affairs.Herein by superfine CA it
Outer all CA are referred to as common CA.So it is right that all CPU other than MCPU can not externally carry out all under silent status
Outer access activity.
In Fig. 1 as it can be seen that after commander server enters silent status, QA is sent by superfine CA to all common CA quiet
Silent entry instruction is simultaneously stopped superfine CA and executes and server entrance or silent all the unrelated Outside Access of releasing.Common CA
After receiving silent entry instruction, stop all Outside Access, and feed back a confirmation message to QA.QA receive it is all
After the confirmation message of common CA, that is, determine that server enters silent status.
So-called QA is substantially a radio unit, and QA substantially belongs to broadcast report to the instruction that all common CA are sent
Text, in the broadcast members list saved in QA, have recorded the common CA in need for receiving QA instruction.Correspondingly, common CA to
The confirmation message of QA feedback, within the scope for substantially also belonging to broadcasting packet, so the transmission of confirmation message is not belonging in institute
The common CA Outside Access of meaning being stopped.
Then, MCPU can modify hardware configuration by superfine CA under silent status.In hardware configuration modification completion
Afterwards, QA sends silent release to all common CA by superfine CA and instructs, and notice restores all Outside Access activity of superfine CA.
Common CA releases instruction in response to silence, and restoring the process that server operates normally is the inverse process into silent process, principle
It is upper almost the same, it is not repeated to describe.
As shown in Fig. 2, server enters or releases the schematic diagram of silent status in the case of more domains NC.In its principle with
The difference of Fig. 1 not substantially.Difference is that QA is other than directly sending instruction to the common CA where it in domain NC, also
The common CA into other domains across the domain NC is needed to send instruction, cross-domain instruction must carry out transfer via NC.The transfer of NC
Belong to additional data interaction process；If there is largely instructing via NC transfer, then occur in data exchange process
Delay will also greatly increase.This means that server enters the time of silent status, that is, influences server and normally transport
The capable time extends.
Also, since there is the limitations of the factors such as agreement, address decoding between the different domains NC, it is likely that lead to MCPU
The hardware configuration that other domains NC can not be modified, which results in the schemes using silent status modification hardware configuration can not be completely real
It is existing.
It is a specific embodiment of the method for the invention referring to Fig. 3~4.Fig. 3 is the server silence method
Flow chart, Fig. 4 are the structural schematic diagram of server in the present embodiment.In the present embodiment, main NC will be known as in the domain NC where QA
Domain, other domains NC are referred to as the sub- domain NC；(the System Monarch CPU, i.e., at main monarch of one SMCPU of middle setting in the main domain NC
Manage device), a DMCPU (Domain Monarch CPU, i.e. domain monarch processor) is respectively provided in each sub- domain NC, so that respectively
DMCPU is in response to the instruction of SMCPU or QA, and independent each sub- domain NC of control enters or releasing silent status, and in silent shape
The hardware configuration in the sub- domain NC is modified in state.
In the present embodiment, it the described method comprises the following steps：
Step 301, SMCPU send silent instruction to DMCPU.
The common CA forwarding silent instruction in the sub- domain NC where step 302, DMCPU to itself.
Common CA in step 303, the sub- domain NC executes the silent instruction.
In the present embodiment, the no longer cross-domain common CA into other domains NC of SMCPU sends silent instruction, but will instruct straight
Receive and send the DMCPU into the sub- domain NC.That is it is different from the prior art, in the present embodiment, SMCPU is to any one
A sub- domain NC need to only send a silent instruction.
It is respectively provided with a DMCPU in each sub- domain NC, so-called DMCPU also includes QA, and the broadcast that the QA of DMCPU is saved
Common CA in members list, in the same only sub- domain NC where record.The so-called DMCPU forwarding silent instruction, can also be with
It is not understood as, after the silent instruction that DMCPU is sent in response to SMCPU, then by the QA broadcast of DMCPU itself, makes in the sub- domain NC
Common CA execute silent instruction.DMCPU common silent instruction of CA forwarding into domain by QA, makes common CA execute silence and refers to
It enables, is equally referred to described in Fig. 1.
It should be noted that there are cache coherency problems in server after terminating in order to avoid silent status, so this
So that common CA is cached release before entering silent status in embodiment, the caching in common CA is restored into memory
In.
The common CA of step 304, SMCPU into the main domain NC sends silent instruction.
Common CA in step 305, the main domain NC executes the silent instruction.
Likewise, there are QA in SMCPU, and the broadcast members list that the QA of SMCPU is saved in the present embodiment, only record is led
Common CA in the domain NC.For the common CA in the main domain NC, SMCPU directly can send silent instruction by QA.Concrete mode with
Process shown in FIG. 1 is identical, is not repeated narration herein.
It should be noted that the instruction of silence described in the present embodiment includes that silent entry instruction and silence release instruction；When
Silent instruct is silent entry instruction, then the silent instruction of the execution is into silent status；When the silent instruction is
Silent instruction is released, then the execution is silent instructs to release silent status.
Shown in Fig. 3~4, for a basic embodiment of the method for the invention, existing for method described in the present embodiment
Beneficial effect is：Silent entry instruction or the silent technical side for releasing instruction are forwarded to the sub- domain NC by DMCPU by SMCPU
Case avoids cross-domain so that SMCPU to any one sub- domain NC only needs a round-trip instruction during server silence
A large amount of instruction bring delays are sent, the time that server enters silent status is shortened.
It is shown in Figure 5, it is another specific embodiment of the method for the invention.In the present embodiment, in aforementioned implementation
It on the basis of example, further combines server and enters after silent status, hardware configuration modification is carried out in each domain NC
Technical solution.Method described in the present embodiment includes the following steps：
Step 501, SMCPU preset configuration modification task, and the configuration modification task is sent to accordingly
DMCPU。
The configuration modification task is to carry out the specific of hardware configuration modification after server enters silent status
Scheme.SMCPU must set the hardware configuration modification for all domains NC in advance.But what is sent to some DMCPU
In the process, to simplify data exchange process, it may not need the hardware configuration modification being sent to it for all domains NC；And only
Only by for the hardware configuration modification in the sub- domain NC where the DMCPU, sent as the configuration modification task.
It should also be noted that, there are cache coherency problems in server after terminating in order to avoid silent status, so
The cooperation modification task is stored in itself not shared buffer memory (such as second level is slow by SMCPU and DMCPU in the present embodiment
Deposit) in, in order to avoid CA and memory are had an impact.
The common CA of step 502, SMCPU into the main domain NC sends silent entry instruction, so that general in the main domain NC
Logical CA enters silent status.
Step 503, SMCPU send silent entry instruction to DMCPU, so that the sub- domain NC where the DMCPU to itself
In the common CA forwarding silent entry instruction, and then the common CA in the sub- domain NC is made to enter silent status.
So far, server enters silent status, and the modification of hardware configuration can start.
Step 504, SMCPU modify the hardware configuration in the main domain NC according to preset configuration modification task.
In abovementioned steps, SMCPU has formulated configuration modification task.So after server enters silent status,
SMCPU carries out the concrete scheme of hardware configuration modification to the main domain NC, modifies in the main domain NC according in the configuration modification task
Hardware configuration.
SMCPU no longer directly modifies to the hardware configuration in other sub- domains NC in the present embodiment.
Step 505, SMCPU make DMCPU according to preset configuration modification task, and the hardware modified in the sub- domain NC is matched
It sets.
In abovementioned steps, DMCPU has received that the configuration modification task that SMCPU is sent, so entering in server quiet
After silent state, DMCPU voluntarily completes the modification of hardware configuration in itself sub- domain NC in place according to the configuration modification task.
By step 504~step 505 as it can be seen that SMCPU and DMCPU is each responsible for NC where modifying itself in the present embodiment
Hardware configuration in domain avoids the cross-domain modification for carrying out hardware configuration.
The common CA of step 506, SMCPU into the main domain NC sends silent release and instructs, so that in the main domain NC
Common CA release silent status.
Step 507, SMCPU send silent release to the DMCPU and instruct, so that the son where the DMCPU to itself
Common CA forwarding silent release in the domain NC instructs, and then the common CA in the sub- domain NC is made to release silent status.
After hardware configuration modification is completed, server will release silent status, restore normal operation.
As seen through the above technical solutions, the present embodiment further exists on the basis of the illustrated embodiment of Fig. 3~4
Beneficial effect be：SMCPU and DMCPU is each responsible for the hardware configuration in the domain NC where modifying itself, avoids cross-domain progress
The modification of hardware configuration, solve due between the different domains NC there is agreement, address decode etc. factors limitation, it is caused
MCPU can not modify the technical issues of cross-domain modification hardware configuration.
It should also be noted that, the silent status of so-called common CA, is in fact divided into deep layer silent status and shallow-layer is silent
Two kinds of state.So-called deep layer silent status exactly breaks off all Outside Access of common CA, common CA is made to lose information completely
Transmission-receiving function.And so-called shallow-layer silent status, it is to retain general under the premise of guaranteeing does not influence the buffer consistency of CA and memory
A part of information transmit-receive function of logical CA；It is similarly to function of the superfine CA under silent status, that is, stops execution and server
Into or release silent all unrelated Outside Access.Under normal conditions, in the silent status of server, all common CA
Enter deep layer silent status.
Based on this point, the method for the invention will have a preferred embodiment below, in the present embodiment, make several general in the domain NC
Logical CA enters shallow-layer silent status, and then other CPU other than MCPU is enable to execute using the CA auxiliary MCPU of shallow-layer silence
The modification of hardware configuration.
It is shown in Figure 6, in the present embodiment, it the described method comprises the following steps：
Step 601, SMCPU preset configuration modification task, and the configuration modification task is sent to accordingly
DMCPU。
The common CA transmission deep layer silence entry instruction and shallow-layer silence of step 602, SMCPU into the main domain NC, which enter, to be referred to
It enables, so that the common CA in the main domain NC enters deep layer silent status or shallow-layer silent status.
In this step, SMCPU selects in the main domain NC the common CA of a part to enter shallow-layer silent status, remaining in the main domain NC
Common CA enters deep layer silent status.
It should be noted that the common CA of direct instruction enters silent status, it is to be carried out by the broadcast of QA；Only need to accordingly it adjust
The broadcast lists of whole QA, it can which common CA selection enables enter deep layer silent status, which common CA enters shallow-layer silence
State.
Step 603, SMCPU send the entry instruction of deep layer silence and shallow-layer silence entry instruction to DMCPU, so that described
Common CA in the sub- domain NC where DMCPU to itself forwards the deep layer silence entry instruction and shallow-layer silence entry instruction,
And then the common CA in the sub- domain NC is made to enter deep layer silent status or shallow-layer silent status.
Similarly, the common CA in part equally enters shallow-layer silent status in the sub- domain NC, remaining common CA enters deep layer silence
State.
So far, server enters silent status, and the modification of simplify configuration can be started.
Step 604, SMCPU modify the hardware configuration in the main domain NC according to preset configuration modification task.
Step 605, SMCPU instruct the common CP U in the main domain NC, using enter shallow-layer silent status common CA, according to
Preset configuration modification task modifies the hardware configuration in the main domain NC.
In the present embodiment, since there are several common CA into shallow-layer silent status in the main domain NC, then with enter shallow-layer
The associated common CP U of the common CA of silent status (other CPU in the main domain NC other than SMCPU), can be in silent status
It is lower to realize certain Outside Access.That is these common CPs U can realize pair of similar SMCPU under silent status completely
Outer access function.
So a part in the configuration modification task will be executed using this part of common CP U in the present embodiment,
Exactly the configuration modification task is completed jointly using the common CP U and SMCPU that are still able to carry out Outside Access.Multiple CPU
The configuration modification task is executed jointly, can shorten the time of task completion.
Step 606, SMCPU make the DMCPU in the sub- domain NC according to preset configuration modification task, modify in the sub- domain NC
Hardware configuration.
Step 607, SMCPU make the common CP U in the sub- domain NC that the normal cache into shallow-layer silent status be utilized to act on behalf of, root
According to preset configuration modification task, the hardware configuration in the child node control domain is modified.
Similarly, it equally can be realized in the sub- domain NC and complete the configuration modification task jointly using DMCPU and common CP U.
It should be noted that MCPU and common CP U are completed jointly in the specific embodiment of configuration modification task, the configuration
Modification task is not only stored in the not shared buffer memory of MCPU, while being also required to be stored in the common of all participation configuration modifications
In the not shared buffer memory of CPU.
The common CA of step 608, SMCPU into the main domain NC sends silent release and instructs, so that in the main domain NC
Common CA release silent status.
Step 609, SMCPU send silent release to the DMCPU and instruct, so that the son where the DMCPU to itself
Common CA forwarding silent release in the domain NC instructs, and then the common CA in the sub- domain NC is made to release silent status.
The time benefit that server enters silent status is as short as possible, after completing configuration modification, can release silence at once
State restores the normal operation of server, and multi -CPU completes configuration modification task jointly, shortens the time of configuration modification, also
Equal to the time for shortening server and entering silent status.
As seen through the above technical solutions, the present embodiment is on the basis of previous embodiment, the beneficial effect further realized
Fruit is：By making a part of common CA enter shallow-layer silent status, realizes and complete to configure jointly using MCPU and common CP U to repair
It changes to business, shortens the time of configuration modification, that is, shorten the time that server enters silent status.
