Specific embodiment
Core of the invention is to provide the monitoring device and server of VR chip on a kind of server master board, first by VR core
The alter signal determining VR chip of piece whether read when the work for determining VR chip occurs abnormal directly against property by operation irregularity
The status register on the VR chip of operation irregularity is taken, to quickly determine abnormal working condition, and then improves monitoring
The timeliness of real-time and abnormality processing.
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Fig. 1 is please referred to, Fig. 1 is the structural representation of the monitoring device of VR chip on a kind of server master board provided by the invention
Figure.
The monitoring device of VR chip includes: on the server master board
The signal adapter 1 being connect respectively with VR chips multiple on server master board, in real time by multiple VR chips one
The alter signal step-by-step of one output is converted to serial data stream；
The BMC 2 connecting respectively with the output end of signal adapter 1 and multiple VR chips reads serial data for working as
Have on stream bit for low level when, determine that the work of low level bit corresponding VR chip occurs extremely, and read immediately
Status register on the VR chip of operation irregularity is to determine abnormal working condition.
Specifically, it is contemplated that when VR chip it is working properly in the case where, the alter signal of VR chip output is high electricity
It is flat；In the case that exception occurs in the work of VR chip, the alter signal of VR chip output is pulled low, and becomes low level；So
The alter interface of multiple VR chips can not be directly linked together on server master board.Moreover, the BMC of the prior art will not be special
Door is reserved multiple GPIO (General Purpose Input Output, general I/O port) and is connect one by one with VR chip,
So the alter interface of VR chip is typically in sky and connects state, the alter signal of output is underutilized.
Based on this, the monitoring device of the application includes signal adapter 1 and BMC 2.The application is converted first with signal
The alter signal step-by-step that multiple VR chips export one by one is converted to serial data stream in real time by device 1, and (i.e. parallel data switchs to serially
Data flow), at this point, the level state that the bit correspondences of one of serial data stream represent the alter signal of a VR chip is (high
Level or low level).As shown in Figure 1, the alter signal of first VR chip (VR1 in figure) corresponds to the first of serial data stream
Bit a, the alter signal of second VR chip (VR2 in figure) corresponds to second bit of serial data stream, and so on
The alter signal of n-th of VR chip (VRn in figure) correspond to serial data stream n-th of bit (n be it is whole more than or equal to 2
Number).
Then, signal adapter 1 exports the serial data stream of conversion to the GPIO of BMC 2, is monitored in real time and is gone here and there by BMC 2
Row data flow.When BMC 2 read on serial data stream have bit for low level when, determine low level bit corresponding VR
The work of chip occurs extremely, and BMC 2 understands the status register on the VR chip of read work exception immediately at this time, thus quickly
Abnormal working condition is determined, to make corresponding abnormality processing.That is, the application no longer circuits sequentially each VR chip of monitoring
Working condition, but according to the level state of alter signal determine VR chip work there is exception after, directly against property read
The status register on the VR chip of operation irregularity is taken, to make BMC 2 when the working condition of any VR chip occurs abnormal
It can promptly respond, to improve the real-time of monitoring and the timeliness of abnormality processing.
The present invention provides a kind of monitoring devices of VR chip on server master board, comprising: respectively and on server master board
The signal adapter of multiple VR chip connections, for being in real time converted to the alter signal step-by-step that multiple VR chips export one by one
Serial data stream；The BMC connecting respectively with the output end of signal adapter and multiple VR chips reads serial data for working as
Have on stream bit for low level when, determine that the work of low level bit corresponding VR chip occurs extremely, and read immediately
Status register on the VR chip of operation irregularity is to determine abnormal working condition.
Compared with VR chip monitoring in the prior art, the monitoring device of the application includes signal adapter and BMC.This Shen
The alter signal step-by-step that multiple VR chips export one by one is please converted in real time by serial data stream by signal adapter first, so
Afterwards by BMC judge whether to have on serial data stream bit for low level, when have bit for low level when, illustrate the bit it is right
There is abnormal, the status register on the VR chip of read work exception immediately at this time in the work of the VR chip answered, so that it is determined that
Abnormal working condition.As it can be seen that the application is first by the alter signal of each VR chip, corresponding to determine whether each VR chip works different
Often, when the work for determining any VR chip occurs abnormal, the state on the VR chip of the operation irregularity is read directly against property
Register to quickly determine abnormal working condition, and then improves the real-time of monitoring and the timeliness of abnormality processing.
