For example, referring to Fig. 1 b, the computer system of the embodiment of the present invention can comprise any one in multi-purpose computer or server system 10, multi-purpose computer or server system 20, multi-purpose computer or server system N, also can be formed by they interconnection.After computer system detects a certain PCIE slot and for example inserted PCIE equipment 111 on PCIE slot 101, computer system starts to inquire about various resource types and the size thereof that PCIE equipment 111 needs.For example, computer system inquires PCIE equipment 111 needs resource type to be respectively memory source, I/O resource and bus resource; Resource size is respectively: memory source 8M, the Bus number of I/O resource 8KB and bus resource maximum is 98.
Wherein, PCIE equipment can be before the computer system power-on self-test stage, and the user inserts the PCIE slot according to individual use habit, and at this moment PCIE equipment is detected in the computer system enumeration stage; PCIE equipment can be also to insert the PCIE slot in computer system operation phase heat, and at this moment PCIE equipment was detected in the computer system operation phase.
For above-mentioned steps S130, after computer system inquires the various resource types and size that PCIE equipment needs, the current available resources of inquiry native system, in the native system available resources, there are the needed various resource types of described PCIE equipment, and, while meeting various resources big or small of described PCIE equipment needs, be described PCIE devices allocation resource.When the computer system available resources do not meet various resource types or when size of described PCIE equipment needs, close the power supply of the PCIE slot that described PCIE equipment is corresponding, stop to described PCIE equipment power supply.
The resource allocation methods of the embodiment of the present invention, whether the PCIE slot that computer system is provided with the hot plug sign by detection has PCIE equipment to insert; Insert PCIE equipment in the situation that the PCIE slot that is provided with described hot plug sign detected, power to described PCIE equipment, and inquire about the size of the needed various resource types of described PCIE equipment and various resources; In described computer system available resources, there are the needed various resource types of described PCIE equipment, and while meeting various resources big or small of described PCIE equipment needs, be described PCIE devices allocation resource.This is a kind of demand assigned resource distribution mode, can effectively utilize resource for computer system, thereby prevents the waste of resource for computer system.
For example, ，Mei road computing machine or server mini system all contain several PCIE slots as shown in Figure 1 b.The total resource of the system of considering is limited, and in the continuous dilation process of system, the number of PCIE slot is in continuous increase, and the total resource of system likely is not enough to distribute to each PCIE slot.
The 2 tunnel systems of below take are introduced respectively the resource allocation methods of prior art and the embodiment of the present invention as example.For example, a server system 10 is arranged, the above has 4 PCIE slots, is respectively PCIE slot 101, PCIE slot 102, PCIE slot 103, PCIE slot 104, and system resource also only enough distributes to 4 slots and use, and always has 4 parts of resources.Wherein, every part of resource all comprises the resource that the PCIE equipment hot swaps such as memory source, bus resource, I/O resource and BAR resource may need.When the another one server system 20 that is also PCIE slot 201, PCIE slot 202, PCIE slot 203, PCIE slot 204 by 4 PCIE slots interconnects by QPI or the technology such as NC interconnection and server system 10 while forming more massive server system, the number of PCIE slot has become 8.
In this case; prior art can be distributed to each server system to resource usually uniformly; for example; can in bios code, be PCIE slot 101, PCIE slot 102 Resources allocation of server system 10; PCIE slot 103, PCIE slot 104 are unavailable; and be slot 201, PCIE slot 202 Resources allocation of server system 20, PCIE slot 203, PCIE slot 204 are unavailable.Prior art also can be according to certain strategy, take certain ratio to come as each server system Resources allocation.For example, can give two server systems with 3:1 proportional distribution resource, for server system 10, can be PCIE slot 101, PCIE slot 102, PCIE slot 103 Resources allocation regularly in bios code, and make PCIE slot 104 unavailable.For server system 20, be PCIE slot 201 Resources allocation regularly in bios code, and make PCIE slot 202, PCIE slot 203, PCIE slot 203 unavailable.
And the resource allocation methods of the employing embodiment of the present invention, at first computer system enables the hot plug attribute that all PCIE slots are PCIE slot 101, PCIE slot 102, PCIE slot 103, PCIE slot 104 and PCIE slot 201, PCIE slot 202, PCIE slot 203, PCIE slot 204, each PCIE slot is arranged the hot plug sign and the detection power supply that power is lower is provided, can avoid like this some PCIE slots always unavailable due to the fixed allocation resource, can effectively utilize the hardware resource of PCIE slot.In the situation that the PCIE slot detected, there is PCIE equipment to insert, computer system determines whether as this PCIE devices allocation resource according to the required resource of PCIE equipment of himself current resource situation and insertion, for example computer system detects rear PCIE equipment 111 and is inserted in PCIE slot 101, at first inquire about the needed resource type of PCIE equipment 111 and size, then inquire about own resource type and size and whether enough meet the demand of PCIE equipment 111, if enough, distribute to PCIE equipment 111 resources, if close not PCIE slot 101 power supplys, make 111 times electricity of PCIE equipment.Resource allocation conditions and the said method of other PCIE slot are similar.
Computer system enables the hot plug attribute of all PCIE slots and can avoid some PCIE slots always unavailable due to the fixed allocation resource, can effectively utilize the hardware resource of PCIE slot.And, when damaging appears in PCIE slot hardware, can transfer to another PCIE slot to PCIE equipment and continue to use, the availability of computer system and maintainability will improve greatly like this, have avoided the waste of the hardware resources such as PCIE slot simultaneously.In the situation that the PCIE slot detected, there is PCIE equipment to insert, computer system determines whether as this PCIE devices allocation resource according to the required resource of PCIE equipment of himself current resource situation insertion, can make its resource distribute on demand, can increase the dirigibility of computer system Resources allocation like this, and can fully effectively utilize the resource of computer system, facilitate the expansion of computer system.
Fig. 2 illustrates the schematic diagram of the data structure of resource according to an embodiment of the invention, and Fig. 3 illustrates the schematic diagram of resource service condition in resource allocation methods according to an embodiment of the invention.The embodiment of the present invention is that the needed every kind of resource of PCIE equipment can adopt unified data structure to manage.
In a kind of possible implementation, the data structure of the resource of distributing in above-mentioned steps S130 mainly can comprise resource type, resource size and a chained list that means the resource service condition.
In a kind of possible implementation, computer system can inquire the computer system available resources according to chained list; If the size of the available resources that inquire exceeds the corresponding resource size of described PCIE equipment needs, the corresponding resource size that from available resources, marking off PCIE equipment needs is distributed to described PCIE equipment.
As shown in Figure 2, this data structure has comprised that resource type is as the resource in Fig. 2 _ 1, resource size is as the Size_1 in Fig. 2, an and chained list that means the resource service condition, as " Used " in Fig. 2 or " Free " meaned a node in the chained list, " Used " means that the corresponding resource of this node distributed use, is unavailable resource; " Free " means that the corresponding resource of this node is not assigned with use, is available resources.In chained list, the corresponding resource of each node can comprise: start address and size, free mark, by which PCIE slot, used, and the pointer of sensing next node etc.
As shown in Figure 3, the situation that has comprised 3 resources use nodes of certain resource, take first node as example: " 0x80000000 " meaned the start address of resource, " 0x1000000 " meaned the use size of resource, " False " meaned that resource has been assigned with use, " 101 " have meaned that the resource in this node distributes to system PCIE slot 101 and use, and " * pNext " meaned to point to the pointer of next node.This kind of resource also remains " 0xE000000 " byte and is not used as can see from Figure 3, can be used for distributing to new PCIE equipment.
In a kind of possible implementation, inserting before the PCIE equipment of PCIE slot as PCIE slot 101 needs Resources allocation as PCIE equipment 111, PCIE equipment 111 can be to the computer system transmitting system current various resources whether meet the inquiry request of self resource requirement, after computer system is received inquiry request, whether the chained list of the data structure by resource goes to inquire about certain resource type the node that is designated " Free ", and whether computer system has the available resources of this resource type.If have, also need to judge whether to meet the resource request size of PCIE equipment 111, if do not meet, also need to continue to search following node, until find " Free " node that can meet PCIE equipment 111 resource request sizes.If can find such node, mean that computer system can provide such resource to PCIE equipment 111, computer system returns to the message of 111 1 resource request successes of PCIE equipment, returns to the start address of this " Free " node simultaneously.Otherwise, return to PCIE equipment 111 resource request failures.
After computer system returns to the message of PCIE equipment 111 resource request successes, if the equal and opposite in direction of the size of this node resource and PCIE equipment 111 requests only needs to revise node parameter and without dividing this node.Wherein, the node parameter of modification mainly can comprise: pointer of the service condition of resource, the slot number that uses this resource and next node etc.If the size of this node resource is greater than the request size of PCIE equipment 111, also to need this node division be two nodes to computer system, and wherein first node identification is " Used ", and size is the device request size, remainder is allocated to second node, still is designated " Free ".Reuse above resource allocation methods, computer system can be just the resource of all PCIE equipment 111 needs of PCIE equipment 111, if there is a kind of resource can not meet the demand of PCIE equipment 111, resource is distributed unsuccessfully.
The resource allocation methods of the embodiment of the present invention, computer system is by adopting the uniform data structure to manage to various resources, can utilize chained list in data structure to inquire easily the available resources of computer system, and, when the size of the available resources that inquire exceeds the corresponding resource size of described PCIE equipment needs, the corresponding resource size that marking off PCIE equipment from available resources needs is distributed to described PCIE equipment.This is a kind of demand assigned resource distribution mode, can fully effectively utilize the resource of computer system, prevents the waste of resource for computer system, has promoted the RAS characteristic of computer system, facilitates the expansion of computer system.
