Abstract
The invention discloses a mainboard VRfirmware upgrading method in a Linux system. Relates to the field of server systems and the Internet industry. When a user purchases a server and the service is on line, the compiled command function can be executed in a Linux system under the condition that the service of the user is not influenced, so that the online upgrade of the memory on the main board of the server and the Firmware of the CPUVRController is realized. The method is very effective for solving faults such as Error Correction Code (ECC) report of the memory during operation of the online service of the user.
Description
Technical field
The present invention relates to server system and internet industry field, particularly relate to the mainboard VR Firmware upgrade method under a kind of linux system.
Background technology
Along with the fast development of server system and semiconductor technology, the polyphase source technology of powering to server master board CPU and internal memory also carries out revolutionary change.Digital power to be accepted by increasing slip-stick artist with its irreplaceable advantage and uses.Traditional is also progressively being made the transition to digital scheme by the simulation solution provider of II type or type III compensation, such as: the main flow VR suppliers such as Intersil, Volterra.Current Intel Grantley platform provides the VR controller of VR13 scheme all to possess PMbus or I2C interface.
The Main Function of PMbus or I2C interface has two: the first passes through the gui software of host computer in the mainboard NPI stage, debugs VR; It two is by this interface, the Firmware debugged is burnt to controller after mainboard volume production.The Master that VR Firmware debug phase and Offline burning adopt all adopts instrument as shown in Figure 1.The core of this instrument is single-chip microcomputer, and instrument is connected to the gui software of host computer by USB interface, is connected to the I2C interface of the VR controller on mainboard by I2C cable.Slip-stick artist, by regulating the parameter on host computer GUI, realizes the debugging to VR.
Usually, if NPI stage VR Firmware design is bad, the problem of some memory compatibility aspects can be there is after mainboard volume production, or report ECC fault under system.Now, need to adjust accordingly the Firmware of VR and optimize, and the code after optimizing is burned onto VR controller.But because the equipment of user is in frame, and wired upper business is in operation, the I2C cable of instrument cannot being connected on mainboard by opening cabinet lid, directly causing completing the optimization to client machine VR Firmware.
Summary of the invention
In order to solve above technical matters, propose the mainboard VR Firmware upgrade method under a kind of linux system herein.The method is simply effective, for solving the partial memory compatibility issue of linux system user, and business on the line not needing to stop client, thus effectively prevent user because business stops the economy of large scale loss of tape.Can realize normally running in the business on the line under client's linux system that do not affect, online optimization and upgrading is realized to the VR circuit of server master board, to improve the confession electrical stability of system.
The technical matters that the present invention will solve and optimize is: when not affecting that on the line under client's linux system, business is normally run, realize the online upgrading of VR Firmware.Its main thought is: by under linux system, perform compiled command functions, realizes the online upgrading of CPU and internal memory VR Firmware on server master board.The mainboard VR Controller of upgrading Firmware is with PMbus or I2C interface.Be below scheme of the present invention:
First, in motherboard hardware, the FW burning of VR controller is the I2C Interface realization reserved by chip.In mainboard I2C topological structure, VR controller defines as slaver equipment.Therefore, need a Master VR Firmware burning.Method is herein the master by the SMbus Host on south bridge PCH chip being defined as VR controller.The SMB HOST I/O port of south bridge PCH chip can realize: under system, have access to extension slaver on their link, to ensure that CPU VR on the differentiation mainboard that I2C topological structure is correct and internal memory VR distributes I2C address.Meanwhile, when address assignment, should ensure, in the address realm of VR chip support, to ensure that the address of each slaver there will not be conflict again.PMbus or the I2C interface of mainboard VR chip and south bridge SMbus Host controller physical interconnection.
Secondly, software aspect is according to I2C Data Transport Protocol compiling generation driving function, and the effect of this driving function is meeting the VR code file programming of form in the NVM of VR chip.Driving function reserves two parameter interface: I2C address and VR code file.Such as: " inspur_updatevr 2A DDR_ABC.txt ", wherein: inspur_updatevr represents driver, 2A represents the I2C address of internal memory ABC passage VR controller, DDR_ABC.txt represents the VR Firmware file that will upgrade.If realize the multiple VR controller of disposable refreshing, only need to call driving function and batch processing command is done in the I2C address of correspondence.
Can realize when not affecting customer service refreshing and upgrading the Firmware of internal memory on server master board and CPU VR Controller.The method is simply effective, can solve the partial memory compatibility issue of linux system user, and business on the line not needing to stop client, thus effectively prevent user because business stops the economy of large scale loss of tape.Can realize normally running in the business on the line under client's linux system that do not affect, online optimization and upgrading is realized to the VR circuit of server master board, to improve the confession electrical stability of system.

Fig. 1 is VR replication tool schematic diagram.
Fig. 2 is hardware topology schematic diagram.
Fig. 3 is software tool pack schematic diagram.
Embodiment
Below by way of embodiment, implementation procedure of the present invention is further illustrated:
With reference to being example in accompanying drawing 2 main memory access AB and CD VR upgrading Firmware:
1) when motherboard hardware designs, with reference to the I2C Topology Structure Design circuit of accompanying drawing 2, it is suitable to define
The I2C address of VR controller, to define AB passage VR address in this example be 0x80, CD passage VR address is E0;
2) USB flash disk is used, new folder called after ' VRcode ' under USB flash disk catalogue.Under driving function as shown in Figure 3, errorlevel and recordable paper are copied to ' VRcode ' folder content;
3) USB flash disk is inserted the host computer system needing upgrading VR Firmware, and guide to this folder content
Under, perform errorlevel ' ./vrprogram.sh '.
After burning success, indicator screen shows:
“0x80 has been updated successfully！”
“0xE0 has been updated successfully！”
Above implementation process is just briefly described the mainboard VR Firmware upgrade method under a kind of linux system in this paper.With reference to can be implemented in the online upgrading any one VR controller being realized under linux system to VR Firmware.(not needing power-off) when not affecting customer service, can solve by online upgrading the various compatibility issues that server system causes because of VR, reducing the risk after sale of product.
