INSTRUCTIONS·· ‘Technical Fields According to the Invention The present invention relates to a test method for network card reset, and in particular to a test method for resetting a network card as a whole. [Prior Art] Since the development of science and technology, the life of modern people has been separated from the Internet. Whether it's connecting the computer to the Internet, or building a local area network (L〇Cal Area Intemet, LAN), the network card (Netw〇rk (10) such as (5), 耽, also known as the network adapter card) It is the most necessary. The network card provides a physical connection for the Bessie communication between the computer systems, and each computer system that wants to access the network has to have an NIC. Most of the notebook computers, desktop computers or food servers on the market have built-in network cards, which shows their popularity. Just because the network card is a very important computer device in the computer, the failure of the network card will open up the network function of the running computer system; if the network card of the important feeding device is issued, the H will affect the normal operation of the road. For the manufacture of the NIC, Weishang must conduct rigorous testing on each NIC before shipping the product. Among them, when testing the core components of the hardware of the network card, the reset (fine) operation of the network card is one of the indispensable test items. The traditional reset test method is based on the individual rules of the network card to operate the NIC's multiple control temporary storage $ (coffee (10) r_ter) to reset the corresponding components in the network card. ^ Not all components have corresponding control registers, so the reset operation can be used to cover all core materials. Furthermore, the reset test method of (4) is required to operate on the side of the network card of the 201118559 Kang, and the code of the test program is not common. In this way, the test program needs to be compiled for each type of network card with reference to the specification. It is very labor-intensive and the handle is not easy to maintain. In addition, the control register will be tested by both the test program and the firmware inside the network card. Therefore, it is necessary to coordinate with the mobile body when controlling the register, so as to avoid data inconsistency or heavy when the test program and the early blade are operated simultaneously. The setup operation failed. However, this practice requires a large and very cumbersome operation of the control register, which is time consuming and error prone. In summary, the 'traditional_card replacement method is not complete, the test code is not available for various network cards, and the operation is complicated, time-consuming and even error-prone. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a test method for network card reset, which is applicable to a network interface card (NIC), a network card and a week.

Since PCIe is backward compatible based on the existing PCI system, when the PCI is replaced with PCIe, the existing PCI system can be converted to pCIe by modifying the hardware of the physical layer without modifying the software on the system. . Further, the ρα bus bar 22 is referred to as a main bus bar connected to the central processing unit .20. The PCI bridge state 24 is used to connect the busbars of different segments. In more detail, the pci bridge 24 is connected as the ρα bus bar 22 of the main bus bar and the remaining ρα sub-bus bar 28. In addition to the network card 26, the PCI device 25 may be, for example, an expansion card such as a sound card or a display card, or an integrated circuit directly disposed on the main board. As shown in Fig. 1, the network card .26 is mounted on the PCI busbar 22 via the PCI bridge 24a. and the PCI sub-busbar .28a, and the PCI device 25 is connected to the PCI bridge 24b and the PCI sub-stream.

The physical layer module 261 processes the lowest layer in the 0SI model, that is, the signal of the physical layer. The physical layer module 261 may include a physical codec layer (PCS), other media related layers (PMA, pMD, _), and an isolation transformer circuit. The medium access control layer module 265 and the logical link control layer module 267 respectively process the signals of the medium access control layer (MAC layer) and the logical link control layer of the data link layer in the osi model. The medium access control layer module 265 may include a microprocessor, a built-in memory, and a direct memory access (1) to control the ^^^111〇1^8 ((%), DMA) controller, etc. . In addition, between the physical layer module 261 and the medium access control layer module 265 and the logical link control layer module k 267, the physical layer medium independent interface and the medium access control layer module (MAC drawing) 265 are performed. communication. The ρα interface 269 is used to communicate the network card 26 with the PCI sub-bus 28 . Next, reference is made to "Fig. 3", which is a flow chart showing the execution of a test method for network card reset according to an embodiment of the present invention. As shown in FIG. 3, the test method of the network card reset may include step S3(): disabling the network card 26; step s32: obtaining a device node corresponding to the network card 26 in the PCI® flow line 22; step S34: Recording the configuration data of the device node as a raw data; Step 6: Obtaining the pci bridge 24a corresponding to the device node in the PCI bus 22: Step S38: Resetting the network card 26 by PCI bridge $24a; Step _: setting the configuration of the device node according to the original data; step S42: enabling the network card %, so that the network 201118559 = initialization; step S44: reading the network card 26 has (4) her - and step S3, The card_% is disabled in the system to avoid data transmission between the network card 26 and the network card 26. Preferably, the method of detecting the network can suspend or remove the network card driver of the network card 26 by means of _. Removing the NIC driver completely prevents other programs from misusing the NIC 26 to avoid unnecessary interference during the reset job. Next, in step S32, the PCI bus bar .22 is scanned to obtain the identification brown (five) of the device node corresponding to the week card 26 in the ρα bus bar a. A ρα skirt μ corresponds to a J-node node; and according to an embodiment of the invention, the network card % has a plurality of comma and each squama corresponds to a device node. The NIC reset test method scans all Ρα devices 25 and has a PCI function address (pciFuneti〇nAddress) or a vendor/device/function identification code (Vender/Device/Function Π) that each button device 25 has. )). Find at least one device node corresponding to the NIC %. The test method of the network card reset and obtain the ID of the device node corresponding to the network card, so as to process the device node in a subsequent step. After the device node corresponding to the network card 26 is obtained, the configuration space data of the standby node is saved as the original data in step S34, so that the network card 26 is reconfigured after the network card % is reset. The configuration space data of the device node is the address mapping of the basic input wheeling system (Basic Input/Output System, BIOS) to the network card 26. For example, in the PCI3.0 standard, the configuration space data can include PC] [Device still, »·Ι| 201118559 = manufacturer/device/function m and six basic address registers (intestines ess: g:S) Capital information of phase card 26 (and its ports). The preferred .4 turn configuration m number is basically the value of her temporary H as the original data. In step S36, according to the pCI specification and the information of the device node, the PCI bridge connected to the PCI bus 22 is obtained, and which PCI bridge 24 is connected to the thin card %. As shown in FIG. The network card 26 is mounted under the PCB bridge 24a. After finding the PCI bridge ϋ 24a connected to the network card 26, the test method of the network card reset also obtains the ω of the PCI bridge (10) to facilitate subsequent processing of the PCI bridge 24a. After obtaining the PCI bridge pool corresponding to the network card 26, in step (10), the network card reset test method resets the entire network card 26 by operating the connection to the PCI bridge If 21⁄2 # PCI sub-stream tearing. According to an embodiment of the present invention, the test method of the network card resets the network card 26 by operating the connection control register address of the PCI bridge 24a. The connection control register system controls the connection specification parameter 'and the enablement of the ρα sub-bus bar 8a(10)b (disable) according to the PCI standard by the connection control register, triggers the NIC % reset signal, The network card 26 is reset as a whole. After the shot 26 is reset, the hardware data (for example, various registers and index values) become invalid. The data stored in the network card 26 may be unusable and cannot be used. At this time, the network card 26 automatically enters a measurement state (5) (10) gamma) or a polling state (pollmg state), and the test method of the bad card reset is when the network card % is in the detection state "wide η 201118559 state or polling state" Step S40 is performed. That is to say, the test method of the network card reset does not wait for the operating system to reconfigure the network card 26 (ie, the network card 26 enters the configuration state, configuration state), and then reconfigures the configuration space data of the device node according to the original data. In other words In step S40, the test method of the network card reset recovers the network card 26, that is, the basic address register of all the ports of the network card 26. Then, in step S42, the test method of the network card reset enables the network card 26, so that the network card 26 is initialized. Preferably, the test method of the network card reset causes the operating system to remount the network card driver to the network card 26 to enable the network card 26. As a result, the network card % is newly touched as a bribe, and the card is %_ The data of the rectification memory should also be restored to the default value. In step S44, the test method of the network card reset reads at least one side of the network card % of the card register In the test, the default value of the _ card temporary storage (four) value is used to judge whether the _ card 26 is working properly after the reset. The NIC register can be one of the media access control layer data related to the storage and read layer, such as RX. Packet Buffer Size Register. The network card register may also store physical sound data related to the physical layer, such as a PHY Control Register. In addition, the network card register may store one of the direct memory access data associated with the DMA. For example, the Kenting X touches the Control Register, and finally in step S46, it is confirmed whether the value of the network card temporary crying read in the step tearing is the same as the preset value set in the NIC D stitchet (Specification). Then, for example, "correct" can be output as the test result; on the other hand, if the value of the network card temporary crying does not restore the domain setting value, the round "failed" as a result. mouth. 12 201118559
