Description
Technical Field
The invention belongs to the technical field of computer firmware, and particularly relates to an automatic recovery system and method for peripheral mounting failure.
Background
When the BIOS is running, some peripherals are connected to a motherboard slot of a computer (terminal), but cannot be normally mounted due to the problem of initialization of software and hardware resources. Sometimes, these peripherals can be restored to normal use by rebooting the computer. Generally, the conventional solution is to insert a peripheral device into a peripheral component interconnect express (PCIe) card slot, read a PCI device in a PCI scan phase or a BDS phase after the BIOS is started, and restart the entire computer (system) if the BIOS fails to detect the peripheral device. The method can not ensure that the peripheral equipment is detected for the second time or even the third time (even more times) of restarting, which can seriously reduce the efficiency and the equipment quality, especially for a server, because the number of memory banks is large, the initialization of the memory at the beginning of starting needs much time, and if the restarting is carried out for many times, the use efficiency can be seriously reduced.

step five, sending a self-checking instruction to the equipment according to a preset interface of the current peripheral equipment;
step six, judging whether the equipment correctly returns a self-checking result;
step seven, recording the abnormal starting condition of the equipment in a starting log;
step eight, judging whether the automatic recovery frequency of the equipment is more than or equal to 1, and if so, turning to the next step; and if not, skipping the self-checking of the current external equipment and carrying out the self-checking on the next equipment. Turning to the step four;
step nine, the BIOS sends the command of electrifying the peripheral board card to the CPLD, and the CPLD enables the peripheral to be electrified again according to the preset electrifying time sequence;

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of hardware connection of an automatic recovery system for failure of mounting a peripheral device, taking a server as an example. The BIOS, BMC, CPLD and peripheral board are connected to the PCH or south bridge. The CPLD is used for power-on time sequence management of the mainboard; the BIOS is used for server hardware initialization and host operating system boot starting; the peripheral board comprises a display card, a RAID card, an optical fiber card and other equipment.
Fig. 2 shows a software structure diagram of the automatic recovery system for failure of mounting a peripheral device. The BIOS is internally provided with an automatic recovery system of the external mounting failure, wherein the automatic recovery system of the external mounting failure comprises a strategy configuration module, an external self-checking module, a power-on restart module and a bus protocol module.
The strategy configuration module is used for configuring a strategy for automatic recovery of the mounting failure of the peripheral equipment, and the configured contents comprise the peripheral equipment type needing automatic recovery of the computer, the maximum cycle power-on frequency of the automatic recovery, fault records, BIOS start-up field storage and a power-on and power-off control method of a single board card of the system.
The peripheral self-checking module is used for carrying out power-on self-checking on the peripheral. The external equipment often has an interface for automatic detection, and when the external equipment is powered on and operated, the external self-detection module acquires an external list and performs equipment inspection through self-detection instructions one by one; if the equipment is normal, returning to a signal with a normal preset working state; otherwise, returning a failure error code or no response to the self-checking instruction;
the power-on restarting module is used for performing power-on restarting on the external equipment through the CPLD and a standard protocol;
the bus protocol module is used for an interface of external communication of the BIOS.
As shown in fig. 3, taking the mount failure of the RAID card as an example, main steps of automatic recovery of the mount failure of the BIOS peripheral device are described:
step one, powering on and starting up a computer.
And step two, initializing the hardware, and loading the automatic recovery system of the external mounting failure.
Step three, the BIOS scans the PCI and other device buses, and the PciaEnumeror () scans and loads the devices to enumerate the external devices; the NewDeviceTreeList () records scanning equipment, compares with a normal equipment list, provides a judgment basis for the loss of the following equipment and generates an equipment list; SelfTestCheck () performs self-checking on scanned devices to ensure correct loading, provides a basis for whether to perform self-checking again, and performs self-checking one by one.
And step four, judging whether external equipment which does not complete self-checking and fault recovery exists currently. In this server, the RAID card is already inserted in the card slot, but it is not successfully scanned.
Step five, sending a self-checking instruction to the equipment according to a preset interface of the RAID card;
step six, BoolTestCheck () judges whether the equipment correctly returns the self-checking result;
step seven, recording a self-checking request into a log by EventRecord (), and skipping the equipment to normally start the whole system if the self-checking frequency of the request is greater than a set value; .
And step eight, judging whether the number of times of automatic fault removal of the equipment is more than or equal to 1. If yes, the next step is carried out; and if not, skipping the self-checking of the current external equipment and carrying out the self-checking on the next equipment. And (5) turning to the step four.
And step nine, prompting failure by the CPLD (complex programmable logic device) self-checking interface, sending a request for re-electrifying to the CPLD, and re-electrifying the RAID card by the CPLD according to a preset electrifying time sequence.
Step ten, the number of times of automatic fault elimination of the equipment is reduced by 1. And (5) turning to the step four.
And step eleven, ending the process.
Under the cooperation of the CPLD and the BIOS, the fault site is recovered in a shorter time, the efficiency of the whole machine is improved, and the pursuit goal of the people is achieved.
The scheme of the invention detects the fault and recovers the fault on site by the cooperation of the BIOS and the CPLD. When the PCI scanning is carried out in the starting process of the BIOS, whether the specific equipment is in place or not is detected, when the scanning mounting or the self-checking fails, the detection is linked with the CPLD to inform that the CPLD hardware needs to be reset and powered on again, at the moment, the CPLD receives a signal of the BIOS and powers on the peripheral again, and the BIOS scans again to enable the peripheral to be recovered to be normally used. If the BIOS is not normally recovered in the period, linkage is carried out again, and after the linkage is carried out for five times, the BIOS is normally loaded and executed.
The design solves the problem that the method for solving the fault at the present stage is long in time, and particularly for the server, the measure has great advantages.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
