Abstract
Method of the present invention is connected to rom chip with synchronous storage system daily record by being multiplexed the I2C signals of PCIE device；Meanwhile using the hot swap characteristics of PCIE device, rom chip relevant information is read at any time, so as to solve the problems, such as loss of data and reproduction BUG information difficulties after power down, improves the efficiency of settlement server dysfunction.
Description
Technical field
The present invention relates to server communication technical field, and in particular to one kind obtains ROM information based on multiplexing PCIE device
Method.
Background technology
PCIE (PCI Express, abbreviation PCI-E), it is one kind of computer bus peripheral component interconnection, it is continued to use
Existing PCI programming concepts and communication standard, but build based on faster serial communication system.I2C buses pass through serial data
(SDA) line and serial clock (SCL) the line transmission information between the device of bus is connected to, have interface line few, control mode is simple
Singly, the advantages that device packing forms are small, and traffic rate is higher, is widely used in carrying out data transmission in server system.I2C believes
Number include CLK and DATA two lines road, in PCIE mark cards, the signal typically be present, will not additionally take board signal
Passage.By I2C agreements, correlation log information can be transmitted to chips such as EEPROM, the correlation in recorder running
Status information.
In server running, particularly design phase early stage, there is certain probability BUG occur, cause machine function different
Normal machine of even delaying, rom chip can not be accessed by I2C, cannot now read correlation log information.At present, in order to solve this
Individual problem, generally require to dismantle issue machine, build test environment again, reappear BUG information, but so can usually destroy original
BUG environment, bring inconvenience to DEBUG work, influence operating efficiency, and part BUG is because of the particularity of its own, it is difficult
With reproduction.So during DEBUG, it should original environment is managed as far as possible not to be destroyed, more accurately to collect LOG, solution
Certainly problem.
For such case, a kind of method that ROM information is obtained based on multiplexing PCIE device of the present application, PCIE is set
Standby upper rom chip is connected to the chips such as BMC/PCH/CPLD, record system log information, must not be answered so as to effective solution
The problem of existing BUG information.
The content of the invention
EEPROM is a kind of conventional rom chip, and data will not lose after power down, while supports electrically erasable and compile again
Journey, it is usually used in record and preserves system journal.By reading daily record, the working condition of system can be analyzed to identify.
PCIe card is the conventional expansion equipment in server, and warm connection function can be realized based on PCIE agreements.The present invention
The described method that ROM information is obtained based on multiplexing PCIE device, it is during normal boot-strap, system journal is total by I2C
Line is transmitted and is stored in eeprom chip, when system goes wrong, using the hot swap characteristics of PCIe card, is removed PCIE and is set
It is standby, original BUG environment so will not have both been destroyed, the log information in EEPROM, therefore energy can be read on other machines again
Enough analyses in time judge BUG reasons, without wasting time and energy rebuild BUG environment again, drastically increase what is solved the problems, such as
Efficiency.
Specifically, a kind of method for obtaining ROM information based on multiplexing PCIE device is claimed in the application, and its feature exists
In this method specifically comprises the following steps：
By the PCIE device with EEPROM, the BMC/PCH/CPLD chips at HOST ends are connected to by PCIE connectors；
PCIE connectors are connected by I2C buses with HOST ends and PCIE device；
Pass through I2C bus transfers and the EEPROM cores that are stored in PCIE device in the running status of the server at HOST ends
In piece.
The method for obtaining ROM information based on multiplexing PCIE device as described above, is further characterized in that, the operation of server
State is real-time storage in eeprom chip.
The method for obtaining ROM information based on multiplexing PCIE device as described above, is further characterized in that, PCIE connectors can
To be high speed connector or golden finger.
The method for obtaining ROM information based on multiplexing PCIE device as described above, is further characterized in that, once system occurs
Problem, PCIE device is removed, being placed on other servers then can normally access eeprom chip in PCIE device, obtain
The running status of server.
The method for obtaining ROM information based on multiplexing PCIE device as described above, is further characterized in that, the operation of server
State is stored in the form of daily record.
Brief description of the drawings
Fig. 1, multiplexing PCIE device of the present invention obtain the operating diagram of ROM information
Embodiment
A kind of method for being multiplexed PCIE device I2C signals of the present application, its specific implementation is by PCIE device
Rom chip be connected to the chips such as BMC/PCH/CPLD, so as to record system log information.
ROM information approaches specific implementation step is obtained to multiplexing PCIE device of the present invention below by one embodiment
Illustrate.
PCIe card is the conventional expansion equipment in server, there is the PCIE slots of correlation, extension in standard server
PCIe card.Warm connection function can be realized based on PCIE agreements, be easy to machine to remove the PCIe card when going wrong.
During normal boot-strap, system journal by I2C bus transfers and is stored in eeprom chip.
Once system goes wrong, using the hot swap characteristics of PCIe card, PCIE device is removed, so will not both destroy original
Some BUG environment, PCIe card can be placed in other servers again, can normally access the eeprom chip on PCIe card, obtain
Log information is taken, further confirms that state of runtime machine, assists analysis to judge BUG reasons.
As shown in Figure 1, the PCIe card with EEPROM is connected to the chips such as the BMC/PCH/CPLD at HOST ends, will be taken
The running status real-time storage of business device uses in eeprom chip for system monitoring and DEBUG.
Wherein PCIE CONN refer to PCIE connectors, the forms such as high speed connector or golden finger can be used, according to plate
The structural confirmation of card.In view of the versatility between different server, preferentially golden finger form is used.
It should be evident that illustrated above is only the specific embodiment of the present invention, for the common skill in this area
For art personnel, on the premise of not paying creative work, other technical schemes can also be obtained according to the embodiment,
Belong to the scope of protection of the invention.
The present invention both can guarantee that original BUG environment was not destroyed, and is easy to debug, is accurately positioned problem, and can obtains in time
Complete log information, without wasting time and energy rebuilds BUG environment, drastically increases the efficiency solved the problems, such as again.
