The management of monitoring and rotation speed of the fan.
It is the display or bridge piece for selecting BMC that hardware aspect CPU controls VGA 2 to cut the display access of 1 chip by GPIO
Collection it is aobvious.System can only support 1 equipment as display when operating normally, by interactive interface, user can choose is BIOS
BMC still collects aobvious, then by BIOS after select can carry out initializing to display equipment and using this equipment as into after system
It shows output source, the GPIO of CPU is adjusted into the level to needed for cutting the corresponding output source of 1 chip to VGA 2 at the same time.To realize
Cooperation on software and hardware.
Production Platform Server one, which is removed, uses BMC as local and remote display output source.But since BMC display performance has
Limit, display resolution 1024x768.Loongson platform bridge piece collection is aobvious, and display resolution can achieve 1920x1080 and show
Effect, delay situation are superior to BMC.Two kinds of display inputs one that the present invention switches are the VGA signals of Godson bridge piece, and one is
The VGA signal of BMC.The method is cooperated jointly by BIOS and hardware circuit realizes that the two signal switches in local display.
Hardware circuit passes through 1 configurable GPIO of Godson CPU, is connected to VGA 2 after pull-up resistor and cuts 1 chip, in detail interconnection situation
It is referred to Part IV block diagram.User can be shown by BIOS configuration interface flexible configuration using bridge piece VGA or
The VGA of BMC.
The included collection of Loongson platform bridge piece is aobvious, and performance is much higher than the display performance of BMC.Therefore it can combine through the invention
BMC and bridge piece show respective advantage, and user can select display mode by simple interface.
Usual Domestic Platform server uses BMC as video card, but Loongson platform is since the integrated collection of bridge piece is aobvious and shows
Show that effect is shown better than BMC, in order to the performance for making full use of collection aobvious, this method is real by bios program and hardware circuit
The switching being locally displayed is showed, user can carry out flexible choice according to demand.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
