Description
Technical Field
The present invention relates to the field of information security, and in particular, to an authentication processing apparatus and method.
Background
In multi-core chip applications, a scenario in which multiple core software or threads operate the same hardware or software is common, where the hardware includes, but is not limited to, a Random Access Memory (RAM), a register, and an Input/Output (IO) channel, and the software generally refers to sharing data among cores. The chip design generally requires that the read and write operations on the same hardware unit or shared data must be serial, otherwise, an error in reading or writing dirty data may occur. If a hardware channel register is configured with a shared area M1, the chip requires that write operations to M1 must be serialized, if two threads a1 and B1 both need to operate the shared area M1 (write first and read second), if a obtains scheduling execution first, it must perform write and read operations to M according to a first, and after a finishes the operations to M, B performs the operations to M in sequence.
In general DSP software, the mutual exclusion of software and hardware is generally solved by a semaphore mechanism, the semaphore ensures that only one thread operates on the mutually exclusive resource at the same time, and the semaphore can be realized by software or hardware. Assuming that the shared region M2 is protected by semaphore S, no matter whether thread a2 or thread B2 is operating, the right to use S of M2 needs to be acquired first, i.e., S-pend is performed, the system determines to give S to a2 or B2 according to scheduling, assuming that a2 acquires the thread of S, i.e., the read-write operation on M2 can be completed, and the thread B2 that does not acquire S needs to wait; after the operation is completed, A2 needs to release the use right S of M2, namely, S-post, B2 and the like are carried out to S, and then the operation on M2 is carried out, so that the serial operation of A2 and B2 on M2 is ensured by the use of S. Software or hardware semaphores are introduced to solve the mutual exclusion problem of shared resources, but the semaphore itself is also a shared resource.
Assuming that an exception occurs while either A2 or B2 is operating M2, i.e., semaphore S has not been released, then no other thread has had a chance to access M2.
In a multi-core application system, the probability of core exception is high, and assuming that a2 and B2 are located on two cores, and the exception hangs up when core a2 operates M2, then an application such as core B2 never acquires S.

Fig. 3 is a flowchart of an authentication processing method according to an embodiment of the present invention. The main body of this embodiment is a second functional unit, and details of the setting process of the authority attribute of the first functional unit by the second functional unit are described. As shown in fig. 3, this embodiment includes the steps of:
In this embodiment, the second functional unit may be configured as a main thread in a multi-thread system, a main core in a multi-core system, or a main system in a multi-mode system. Correspondingly, the first functional unit may be configured as a slave thread in multithreading, or other cores in a multi-core system, or other systems in a multi-mode system.
Further, receiving the request message for accessing the shared resource sent by the first functional unit specifically includes: receiving request messages for accessing shared resources sent by a plurality of first functional units, wherein the request messages carry information of the first functional units.
The second functional unit inquires whether the shared resource is in the operated state, if the shared resource is not operated, namely is idle, the second functional unit replies that the first functional unit can operate, and if the shared resource is in operation, the second functional unit waits for the end of the last processing. In the embodiment, by adding the authorization flow of the first functional unit to the second functional unit, the resource operation conflict among multiple threads, multiple cores or multiple modes is solved, the bus or system abnormality caused by the simultaneous rewriting or unlocking of the hardware register by the multiple functional units is avoided, and the software shared resource is prevented from being wrongly written or wrongly read by the multiple functional units.
Further, the querying the operation state of the shared resource, and when the shared resource is idle, sending an authorization message to the first functional unit specifically includes: and generating a scheduling order list according to the information of the first functional unit, and sending an authorization message to the first functional unit in the scheduling order list when the shared resource is idle. At this time, the first functional unit in the non-first order of the scheduling order table may perform other operations such as loading, unloading or upgrading, which do not affect the operation and use of other first functional units.
After the first functional unit initiating the application obtains the authorization, the shared resource is operated, and after the operation is finished, the second functional unit receives the permission release request message initiated by the first functional unit.
Further, the method further comprises: when the access time of the first functional unit for accessing the shared resource exceeds the threshold time, the first functional unit terminates the access of the shared resource, and the state of the shared resource is set to be idle.
Further, terminating the access of the first functional unit to the shared resource specifically includes: and setting the software mark of the first functional unit for accessing the shared resource to be invalid.
Specifically, when the first functional unit accesses the shared resource, the software flag of the first functional unit is set to be valid, at this time, the second functional unit performs timing monitoring on the authorized operation, when the timing is exceeded, the software flag of the first functional unit becomes invalid, the second functional unit forcibly withdraws the operation authority, sets the state of the shared resource to be idle, and authorizes the shared resource to other first functional units waiting for authorization. The process improves the availability ratio of the single board, reduces the risk that certain resources are unavailable due to the fact that the certain resources are possibly hung up randomly originally to the extent that only the second functional unit is hung up and shared resources are unavailable, supports the reset and recovery of the single core, and provides system robustness. For a multi-mode system, if one system fails, the operation of the other system and the use of the resources of the same type are not influenced, and the other system can be loaded, unloaded or upgraded when the one system operates. Single-core reset is supported in the multi-core system, and specification and resource dynamic adjustment of core granularity are supported.
Fig. 4 is a first authentication processing application interaction diagram provided in the embodiment of the present invention. As shown in fig. 4, the first functional unit is thread a and thread B, the second functional unit is MAIN functional unit BB _ MAIN, and the shared resource is M. The application interaction process in the authentication processing system is as follows:
step 401, a plurality of first functional units initiate an operation application to a second functional unit. And the thread A and the thread B initiate operation application to the BB _ MAIN.
In step 402, the second functional unit checks the operating status of the shared resource. The BB _ MAIN receives and processes the request message of step 401, generates a scheduling order schedule according to the time when the thread a and the thread B initiate the operation application, and checks the M operation state.
And 403, when the shared resource is idle, the second functional unit authorizes the plurality of first functional units according to the scheduling order. When the M is idle without other operations, the BB _ MAIN authorizes the thread A and the thread B according to the scheduling order, and the thread A is supposed to obtain the authorization message earlier than the thread B, so that the thread A accesses the shared resource. At this point, thread B may perform other operations, such as upgrading, loading, etc. of thread B.
In step 404, the first functional unit accesses the shared resource. The operation of the thread on M is encapsulated in step 404.
Step 405, after the first functional unit finishes operating, the first functional unit sends an authority idle message to the second functional unit. And after finishing accessing the shared resource, the thread A sends an authority idle message to the BB _ MAIN. Under normal conditions, BB _ MAIN receives the authorization release message sent by the thread A, recovers the authority, grants the operation authority to the required thread B, and B receives the authorization message and then executes the operation of the step 404.
The embodiment further comprises step 406, the second functional unit enforces the withdrawal of the authorization rights.
It should be noted that the exception condition includes, but is not limited to, exception and loss of the permission release message when the thread a operates the shared resource. And BB _ MAIN monitors the timing when the thread A operates the M, and forcibly withdraws the operation authority of the thread A to the M when the time threshold is exceeded, and continues the next authority distribution processing.
Compared with the prior semaphore mechanism, the method has the advantages that many chip inter-core or inter-thread messages are realized by hardware, so that the loss of the semaphore on efficiency is not much larger than that of the semaphore directly by the hardware; meanwhile, the semaphore pend generally adopts a dead mode and the like, the thread B cannot process other tasks when waiting for the S, and after a message mechanism is adopted, the thread B can also process other tasks when waiting for the message authorization, so that the parallelism of the system can be increased. By adding the authorization flow of the first functional unit to the second functional unit, the resource operation conflict among multiple threads, multiple cores or multiple modes is solved, and the bus or system abnormity caused by the simultaneous rewriting or unlocking of a hardware register by the multiple first functional units and the error writing or error reading of the software shared resource by the multiple first functional units are avoided; the availability ratio of the single board is improved, the risk that certain resources are unavailable due to the fact that the single board can be hung at will is reduced, only the second functional unit is hung, and shared resources are unavailable, and system robustness is provided; furthermore, for a multi-mode system, when one system runs, the other system can be loaded, unloaded or upgraded, and when one system fails, the running of the other system and the use of similar resources are not influenced.
Fig. 5 is a diagram of a second authentication processing application interaction according to an embodiment of the present invention. As shown in fig. 5, the multimode resource management of the ethernet ETH channel is taken as an example to illustrate the application interaction process in the authentication processing system. The first functional unit is application software APP, the second functional unit is a baseband BB, and the shared resource is a driver DRV.
By using the technical scheme of the invention, the register operation of the ETH is brought into the management of an authorization mechanism, and the hardware can be operated only by obtaining the authorized APP, thereby ensuring the serial. Meanwhile, the authorization mechanism is realized in BB, which is invisible to APP, and for DRV, as BB is used to ensure mutual exclusion, DRV can not use semaphore any more, DRV realization is simplified, and overall system efficiency is improved.
Compared with using semaphores, the upper layer software BB isolates the multimode resources, but the bottom layer driving DRV still uses the semaphores to ensure that the multi-core operation is not conflicted when the channel priority register is operated, the lock is operated and the unlock is operated, coupling is introduced, and the condition that one thread is operated abnormally (the core is hung up) to cause the other thread to be abnormal exists. The embodiment simplifies the bottom-layer DRV, does not need various considerations of service scenes, and improves the DRV efficiency.
It is understood that the present embodiment is not limited to baseband L1 software applications, as L2/L3 software may be used. The high-level software also has the requirements of mutual exclusion of shared resources and isolation of multi-mode resources, and the same problems can be solved by the same method.
All multimode soft systems can refer to the application, and the system related to multimode resource management and fault isolation can be technically designed by the scheme of the invention.
The embodiment of the invention can be applied to various scenes such as single-core reset, multi-mode fault, fault single-board loading, single-system loading and the like, when the first functional unit accesses the shared resource, the authentication processing method and the authentication processing device are adopted, solves the resource operation conflict among multiple threads, multiple cores or multiple modes by adding an authorization flow, avoids the bus or system abnormity caused by the simultaneous rewriting or unlocking of a hardware register by a plurality of functional units, avoids the error writing or the error reading of the software shared resource by a plurality of functional units, for the multi-mode system, if one system fails, the operation of other systems and the use of the same kind of resources are not influenced, for a multi-mode system, when one system runs, the other system can be loaded, unloaded and upgraded, and in the DSP, the implementation of a bottom driver is simplified, various considerations of a service scene are not needed, and the efficiency of the bottom driver is improved; the availability ratio of the single board is improved through an authority recovery mechanism, the risk that any core is hung to death and certain resources are unavailable is reduced to the risk that the resources are hung to death only by a main core (the core where the authorization management is located), single-core reset is supported in multi-core, the specification of core granularity and dynamic adjustment of resources are supported, and the system robustness is improved.
