Following embodiment will further specify the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
As shown in Figure 1, be the Organization Chart of network interface card naming system of the present invention preferred embodiment.
Network interface card naming system 10 runs in the computing machine 1, also comprises a plurality of network interface cards 11 (only drawing among the figure one) in the described computing machine 1.Described network interface card 11 is PCI equipment, and each PCI equipment all occupies a unique pci bus position in computer system (as linux system).This pci bus position is by network interface card 11 residing bus (bus) positions, equipment (device) position and function (function) determining positions, and described bus location, device location, POF number are identified by Bus number, device number, function accordingly.
The form of expression of described pci bus position is: the bus position: .function position, device position hereinafter abbreviates the pci bus position as BDF.Among this BDF, .function position, device position can not be changed, the bus position may be because of BIOS (Basic Input Output System, Basic Input or Output System (BIOS)) change and changing, therefore in the different running environment of linux system, the bus position of all PCI equipment all may change along with the change of BIOS is corresponding, but to the 10 not influences of name network interface card 11 of network interface card naming system.
Since each network interface card 11 all has a unique BDF, and this BDF is easy to be found by kernel, thereby so network interface card naming system 10 utilize the network interface card 11 of BDF to be numbered the title of determining network interface card 11.Network card equipment can't can't be found because of not existing of driving of network interface card, so be to pre-exist equipment, network interface card naming system 10 is to carry out when network interface card drives loading at inner nuclear layer to the name of network interface card 11.
Described network interface card naming system 10 comprises acquisition module 100, processing module 101, order module 102 and name module 103.The function of each module will describe in detail in conjunction with the process flow diagram of Fig. 2.
As shown in Figure 2, be the process flow diagram of network interface card naming method of the present invention preferred embodiment.
Step S10, when opening initialization BIOS, described acquisition module 100 obtains the value of the pci bus position of all network interface cards 11 in the computing machine 1.The described value of obtaining the pci bus position of network interface card 11 is namely obtained the BDF value of network interface card 11.
Step S11, described processing module 101 is processed into a signless integer with the value of the pci bus position BDF of each network interface card 11.
In this preferred embodiment, processing module 101 is taked the method that is shifted, move to left 12, device of bus number of each network interface card 11 number are moved to left 4, and will move to left after 12 bus number, after 4 device number and function number of moving to left are carried out position or method of operating the BDF of each network interface card are processed into a signless integer.In other embodiments, also can take all possible method that BDF is processed into a signless integer.
For example, the BDF of three network interface cards 11 is arranged, be assumed to be BDF0, BDF1 and BDF2, BDF0 is 02:04.0, and BDF1 is 02:03.1, and BDF2 is 02:03.3.Processing module 101 with all BDF be shifted and the position or the operation after, be set at each BDF under the situation of 16 hex value, the signless integer of BDF0 correspondence is 0X02040, and the signless integer of BDF1 correspondence is 0X02031, and the signless integer of BDF2 correspondence is 0X02033.
Step S12, all signless integers that described order module 102 will obtain are arranged according to a default order, and determine the sequential index value of all network interface cards 11 by the order of arranging.Described default order can be arranges all signless integers according to order from small to large, maybe all signless integers are arranged according to order from big to small.
Need to prove that in linux system, the name to network interface card 11 in inner nuclear layer all is from eth0, sequentially down carries out called after eth1, eth2 equivalence again.Corresponding in the inner nuclear layer to the naming method of network interface card 11, the sequential index value of order module 102 is followed successively by 1,2 equivalences again since 0.
For example, the signless integer of above-mentioned BDF0, BDF1 and BDF2 correspondence, if order module 102 is arranged it by order from small to large, the order after then arranging is: 0X02031,0X02033,0X02040.The sequential index value of the network interface card 11 of BDF0, BDF1 and BDF2 correspondence is respectively 2,0,1.
Step S13, described name module 103 is named corresponding network interface card 11 according to the sequential index value.
For example, the network interface card 11 of BDF0, BDF1 and BDF2 correspondence can be distinguished called after eth2, eth0 and eth1.
When loading the network interface card driving, the kernel naming rule just can determine that the title of network interface card 11 is respectively: eth0, eth1, eth2 etc. according to this " sequential index value " then.
The BDF data that the mode that the present invention names network interface card 11 is based on network interface card 11 in the PCI equipment determine, and BDF is determined by BIOS, has therefore solved the problem of the title change of network interface card 11 effectively.
Above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
