Description
Technical field
The present invention relates to Computer System Design technical field, be specifically related to a kind of method for designing showing start progress in the server Post stage.
Background technology
Server has the process of a startup self-detection in start process, and we become the POST stage, the POST stage because video card equipment also no initializtion complete, so time system do not show that signal exports.Because CPU quantity is many, internal memory and the peripheral hardware of carry are more, and POST process time also can be very long.During this period of time user can't see display information, and display is no signal condition always, if the supplementary means of being not added with, is the start progress that cannot obtain system, directly influences whether the operating experience of user.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problems referred to above, the present invention proposes a kind of method for designing showing start progress in the server Post stage, BMC, MCU, OSD, video superimpose chip is adopted jointly to realize video superimpose technology, at server display interface Overlapping display start progress, thus allowing, user is convenient observes system boot state intuitively over the display.
The technical solution adopted in the present invention is:
A kind of method for designing showing start progress in the server Post stage, video superimpose technology is applied in server in motherboard design by described method, by controlling MCU, OSD(on-screendisplay) chip and video superimpose chip, each ingredient is by bus interconnection together, start progress information is shown on display, wherein:
1) BMC(BaseManagementController, baseboard management controller): integrated network card function, interconnect with South Bridge chip in band, by system interaction inside and outside band, obtain system boot progress msg, and MCU can be sent the data to by serial ports；Wherein South Bridge chip is a part for host computer system, is interconnected by PCIE and lpc bus and BMC, in real time boot-strap information can be sent to BMC；
2) MCU: process the BMC start progress data sended over, data are made video data and is sent to OSD, provide video synchronization signal to OSD simultaneously；
3) OSD chip: OSD chip receives the MCU data sended over and changes into display signal, shows with progress bar or percents, the video synchronization signal that MCU sends over could alter that progress display image position over the display and size；OSD chip is by I2C interface and MCU interconnection, and systems progress information is changed into video signal is sent to video superimpose chip；
4) video superimpose chip: system display signal and osd signal can be received simultaneously, both are overlapped outputting VGA signal to display.
MCU(MicrocontrollerUnit；Micro-control unit), also known as one chip microcomputer (SingleChipMicrocomputer) or single-chip microcomputer, it is central processing unit (CentralProcessUnit；CPU) frequency and specification do suitable reduction, and by the perimeter interface such as internal memory (memory), enumerator (Timer), USB, A/D conversion, UART, PLC, DMA, even LCD drive circuit is all incorporated on one chip, form the computer of chip-scale, do various combination control for different application scenarios.
Described MCU possesses UART, I2C interface function, UART interface and the BMC interconnection in server system, obtain system boot progress msg, by I2C bus, data are dealt in OSD chip, MCU is sent to OSD and does display signal conversion after start progress information being processed, simultaneously MCU can send video synchronization signal (HSYC VSYC) to OSD, is used for controlling display image position over the display and size.
Described system boot progress shows only before the system post stage does not enter into display state, and after system boot enters display state, BMC is notified that OSD chip is turned off by MCU, cancels system boot progress and shows.
The workflow of described method is divided into two parts, and a part is the system electrification post stage, and Part II is after system boot enters display state:
1), the system electrification post stage:
After system electrification, starting the equipment such as CPU, internal memory, IO are carried out self-inspection, now BMC integrated graphics card also no initializtion, system is without display signal output；
BMC, as band external system system interaction interior with band in real time, collects system boot information, is sent to MCU；
MCU processes after receiving the BMC Serial Port Information sent, and converts progress msg to, and data are sent to OSD in the specific format；
OSD receives and changes into image display signal (R, G, B) video superimpose chip after MCU sends start progress information；
The image of start progress is shown that the system display that is added to exports to display by video superimpose chip, thus user can see current system start progress from display；
2), after system boot enters display state:
System boot enters after display state, and user then need not know start progress by the mode of Overlapping display, therefore after BMC judges that video card initialization completes, can stop continuing transmission start progress information to MCU；
BMC can turn off MCU and OSD simultaneously so that it is quits work；
Now video superimpose signal only has system display signal input, shows image after display is seen system boot normally.
The invention have the benefit that
The present invention at server display interface Overlapping display start progress, can allow user conveniently observe system boot state intuitively over the display, it is achieved scheme is simple and reliable, less costly, it is possible to large increase user operation is experienced, improving product competitiveness.
