Specific embodiment
In order to make those skilled in the art more fully understand application scheme, below in conjunction in the embodiment of the present application
Attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is only this
Apply for a part of the embodiment, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall in the protection scope of this application.
In order to solve in the prior art, under the scene of inadequate resource, resource is fought for leading to resource allocation between two ports
Unevenness, and then the problem of cause the performance of two ports to be shaken, the embodiment of the present application provides a kind of for solid state hard disk dual-port
Data processing method, referring to Fig. 1, this method comprises:
S101, it is directed to intended recipient queue, obtains the first message that the intended recipient queue receives.
The method that the embodiment of the present application mainly passes through poll determines how to handle first message under out-of-resource condition.SSD
Dual-port in, a port is referred to as 1 port, another port is referred to as 2 ports.16 cores are shared in the CPU of SSD,
All cores are after entering polling status, and the task that each core is undertaken is different, and one of core is referred to as data administrator
(Data Manager, abbreviation DM), DM are used for other cores in the message that receiving host is sended over by port and CPU and send
Message.It is mainly receiving queue (Inbound Queue, the letter due to DM that DM, which receives the message that other cores are sent in CPU,
Claim IBQ) receive message from port after slightly handle, then by transmit queue (Outbound Queue, abbreviation OBQ) send
The processing of other cores is given, other cores pass through corresponding OBQ after processing is completed and are sent to DM.
If the received message for coming from port of the IBQ of DM, the classification of this IBQ is first kind IBQ, if the IBQ
Opposite end is 1 port, which is named as IBQ_P1, if the opposite end of the IBQ is 2 ports, which is named as IBQ_P2.
The opposite end of other IBQ of DM is other cores in SSD, the classification of these IBQ is the second class IBQ.
Message in first kind IBQ can consume the resource in DM, and the message in the second class IBQ can discharge the money in DM
Source.
The intended recipient queue is determined according to object queue serial number；The object queue serial number identifies the target
The sequence of the classification of receiving queue and the object queue in all receiving queues identical with its classification.
In the present embodiment, queue serial number (the Current Polling Queue of this i.e. poll of object queue serial number
Index, abbreviation CPQID), target port serial number is port serial number (Next Polling Port Index, the letter of next poll
Claim NPPID).
Before executing S101, the CPQID and the NPPID can be initialized.For example, the CPQID is assigned a value of
First IBQ indicates the poll since first IBQ, is carried out S101-S106 for each IBQ；NPPID is assigned a value of
IBQ_P1 indicates that first kind IBQ to be treated next time is the IBQ that opposite end is 1 port.
In at any time, not necessarily all IBQ can receive first message, if IBQ is not received by
First message, then without carrying out subsequent processing to the IBQ, therefore, before executing S101, it can be determined that the intended recipient team
Whether column receive the first message；If it is not, the object queue serial number is then increased by 1, re-execute described in the judgement
The step of whether intended recipient queue receives the first message.
S102, determine whether the intended recipient queue is first kind receiving queue according to the object queue serial number, if
It is then to execute S103.
S103, judge whether the object queue serial number is equal to target port serial number, if so, executing S104.
S104, judge whether the resource in data management module meets preset condition, if it is not, S105 is then executed, if so,
Execute S106.
The first kind receiving queue is receiving queue corresponding to the port of the solid state hard disk；The target port sequence
Number identify the affiliated port of first kind receiving queue of this poll priority processing.If judge target IBQ for first kind IBQ, then,
The opposite end for then illustrating target IBQ is port, still, since SSD includes two ports, the corresponding port target IBQ being polled to
It is whether equal with the affiliated port first kind IBQ of this poll priority processing, by the different processing method of correspondence.
If judging, the object queue serial number is equal to the target port serial number, executes S104；If judging the target
Queue serial number is not equal to the target port serial number, then judges whether the corresponding receiving queue of the target port serial number receives
Second message；If so, judging whether the resource in the data management module meets preset condition；If so, processing described the
The target port serial number is assigned a value of the object queue serial number by two message, re-executes the judgement object queue
Whether serial number is equal to the step of target port serial number.
For example, CPQID is equal to IBQ_P1, NPPID IBQ_P1, by judging that the object queue serial number is equal to the mesh
Port serial number is marked, then executes S104；If CPQID is equal to IBQ_P1, NPPID IBQ_P2, by judging the object queue sequence
Number it is not equal to the target port serial number, then can not continues to execute subsequent step to intended recipient queue corresponding to IBQ_P1
Suddenly, but first receiving queue corresponding to IBQ_P2 is polled, then, then to intended recipient queue corresponding to IBQ_P1
Subsequent step is executed, that is, judges whether the corresponding receiving queue of target port serial number receives second message；If so, judging institute
State whether the resource in data management module meets preset condition；If so, the second message is handled, by the NPPID assignment
For the CPQID, i.e., NPPID is assigned a value of IBQ_P1, re-executes S103.
S105, it keeps the value of the target port serial number constant, shields the intended recipient queue, and by the target team
Column serial number increases by 1, re-executes S101.
If judging, the resource in DM is to be unsatisfactory for preset condition, illustrates the inadequate resource in DM, at this point, in order to avoid money
Source is fought for, and the value of the target port serial number can be kept constant, shields the intended recipient queue, and by the object queue
Serial number increases by 1, S101 is re-executed, using next receiving queue as intended recipient queue.Since intended recipient queue is shielded
It covers, then, poll can not also check the intended recipient team next time, just can be again until the resource abundance in DM
Open shielded intended recipient queue.
S106, the processing first message, are assigned a value of the non-object queue serial number for the target port serial number, execute
S101。
If judging, the resource in DM is to meet preset condition, illustrates that resource in DM is sufficient, though to first message into
Row processing, the problem of resource is fought for will not occurs, at this point, handling the first message.Due to corresponding to a port
Intended recipient queue in first message handled, as port assignment resource, in order to enable dual-port performance
Stablize, resource allocation it is uniform, then, next, should the first message in the intended recipient queue to another port carry out
Target port serial number, therefore, can be assigned a value of the non-object queue serial number, S101 be re-executed, to another by processing
The corresponding receiving queue in port is polled.
Wherein, non-targeted queue serial number, that is, non-CPQID, non-CPQID are meant if CPQID is equal to IBQ_P1, non-
CPQID is equal to IBQ_P2；If CPQID is equal to IBQ_P2, non-CPQID is equal to IBQ_P1.
It should be noted that since DM processing first message needs to consume the resource in DM, in order to avoid in DM
Resource consumption is excessive, and the item number for the first message being capable of handling has certain limitation, in such a case, it is possible to which being arranged can locate
The maximum item number of the first message of reason.For example, under normal circumstances, 8 can be set to.
It should be noted that in S102, if determining that the intended recipient queue is not according to the object queue serial number
First kind IBQ, but the second class IBQ, the second class IBQ be in CPU in addition to the DM receiving queue corresponding to other cores,
Due to being the resource for discharging DM for DM when other cores handle first message in addition to the DM in CPU, i.e. in increase DM
Therefore resource if intended recipient queue is the second class IBQ, can directly handle the first message, and by the target team
Column serial number increases by 1, re-executes S101.Due to resource when the second class IBQ handles first message in release DM, so that DM
It is middle to there are enough resources to handle the first message received, therefore, it can will open shielded IBQ, hold again before
Row S101.
The embodiment of the present application has the advantage that it can be seen from above-mentioned technical proposal
