Specific embodiment
The technical solution of the present invention is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
In order to solve the technical problem in background technology, the embodiment of the present invention provides a kind of method of online updating kernel,
The method is applied to electronic equipment, and the function that the method is realized can be by the processor caller code in electronic equipment
To realize, certain program code can be stored in computer-readable storage medium, it is seen then that the electronic equipment at least include processor and
Storage medium.
Fig. 1 realizes schematic flow sheet for the method for embodiment of the present invention online updating kernel, as shown in figure 1, the method
Including：
Step S101, determines processor cores set, and the processor cores set is included on server by be updated
Processor cores scheduled in system supervisor；
Here, the electronic equipment can be various types of with information processing capability during specific embodiment
Server apparatus, particularly relate to SMP server etc..Symmetric multi-processors structure (SMP, Symmetric Multi-
Processing) be most common one kind in symmetric multiprocessor (CPU, Central Processing Unit) system, it
Do not have too many practical use among common business, domestic. applications, but made in specialty, such as three-dimensional, software application of drawing
In obtain very good performance, be the good partner for setting up cheap work station.With the raising of the users' level of application,
Only it has been difficult to meet the demand of practical application really using single processor, thus each manufacturer server is one after another by using
Symmetric multiprocessing system solves this contradiction.Commercially the processor of this kind of type is general based on 4 or 8, there is few
Number is 16 processors.But in general, the machine scalability of SMP structures is poor, it is difficult to accomplish more than 100 multiprocessings
Device, conventional is usually 8 to 16, but this is enough for most users.The benefit of this machine exists
Little in the difference of its occupation mode and microcomputer or work station, the change of programming is comparatively smaller, originally uses microcomputer work
If the program that work station is write will be transplanted on SMP machines used, it is also relatively easy to change.The type of SMP structures
Availability is poor, because 4 or 8 processors shared an operating system and a memories, once operating system occurs
Problem, just paralysis is fallen completely for whole machine.Most common symmetric multiprocessing system leads in personal computer (PC) server
Frequently with 2 tunnels, 4 tunnels, 6 tunnels or 8 path processors, the technology of most critical is how preferably to solve multiple processors in smp system
Mutual communication and coordination problem.
In general, the system supervisor on server can be to that should have a dispatch list (commonly referred to as kernel
Dispatch list), quantity, the scheduled treatment of the processor cores scheduled in the system supervisor are included in dispatch list
Mark (ID, Identity) of device kernel etc..
In general, the concept of CPU is successively from big to small node (Node), slot (Socket), physics kernel
(Core is also called core), logic processor (Logical Processor).With the development of multi-core technology, by multiple CPU
It is packaged together, this encapsulation is referred to as Socket.Each kernel is referred to as Core in Socket.In order to further lift CPU
Disposal ability, Intel introduces hyperthread (HT, Hiper-Threading) technology again, and a Core is opened after HT,
Operating system appears to be two cores, and certain this core is concept in logic, so also referred to as Logical processor.This
Processor cores in embodiment refer to physics kernel.
Step S102, by first processor kernel in the processor cores set from system supervisor to be updated
Free out；
Here, during realization, step S102 is included according to ACPI (ACPI, Advanced
Configuration and Power Interface) technology by first processor kernel in the processor cores set from
Freed out in system supervisor to be updated, wherein the first processor kernel can be by system pipes to be updated
Any processor kernel in reason program scheduler list.
According to ACPI (ACPI, Advanced Configuration and Power
Interface) logic processor free time (logical processor idle) technology of definition, can be by single processor
Core is removed from the dispatch list of current inner；Then a new kernel is run from the CPU core；By remaining all of CPU
Kernel and business are moved to new kernel up successively；Finally discharge old kernel.
Step S103, new system management program is operated on the first processor kernel of free time；
Here, the system supervisor before new system management program is used to update is (i.e. to be updated in step S101
System supervisor).
Step S104, the first service processor that will be currently running is operated in the new system management program.
Here, service processor refers to pending business, generally, system supervisor during realization
On can run some virtual machines, these virtual machines be used for processing server business, so, when new system management program set up
After on the idle processor cores, it is possible to which the operational processor on original old system supervisor is moved to new system pipe
Come in reason program.
Here, the first service processor can be any service processor on system supervisor to be updated.
In the embodiment of the present invention, processor cores set is determined, the processor cores set includes being treated on server
Processor cores scheduled in the system supervisor of renewal；By first processor kernel in the processor cores set from treating
Freed out in the system supervisor of renewal；New system management program is operated on the first processor kernel of free time；Will
The first service processor being currently running is operated in the new system management program；So, it is possible to realize that dynamic updates kernel,
So as to avoid that business is impacted.
