Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
At present, the standby power protection of a server is generally monitored in a direct polling GPIO mode, the polling time is poor, waiting delay of a polling response is waited, and on the premise that the standby power is limited, the power consumption in the delay process is enough to influence the standby power protection effect, so that the standby power protection has hidden danger of data storage failure.
The control method takes the NMI interrupt signal as the premise, and polls and reads the AC power supply state when the NMI interrupt signal is lost, so that the control method has the advantage of quick sensing, can improve the efficiency of standby power protection, saves the power consumption of the standby power supply, and improves the reliability of data protection.
The embodiment of the application discloses a control method for standby power protection, which is shown in fig. 1 and comprises the following steps:
s1: receiving an NMI interrupt signal sent by a CPLD when the CPLD detects that the PSU is powered down by AC;
specifically, the generation of the NMI (Non Maskable Interrupt, non-maskable interrupt) interrupt signal is assumed to be a kernel service status, so the control method in this embodiment further includes, before receiving the NMI interrupt signal sent when the CPLD (Complex Programmable Logic Device ) detects that the PSU (Power Supply Unit, power module) has an AC power failure:
the core service state is trapped and the NMI interrupt signal is waited to be received.
Specifically, the process of trapping the kernel service state comprises calling the trapping kernel service state through the ioctl system, so that the quick perception of the user state program is realized.
S2: according to the NMI interrupt signal, running an interrupt processing function so that the interrupt processing function reads the AC power supply state in the GPIO and monitors an AC power-down thread when the AC power supply state is a power-down state;
s3: entering a standby power process;
it is understood that the standby process is performed according to a conventional standby current process.
Further, after entering the standby power process, the method further comprises: and backing up the cache data and/or the kernel data to the hard disk. It will be appreciated that the operation of backing up the cached data or kernel data to the hard disk is independent of the conventional power backup data protection, so as to further improve the security, reliability and integrity of the critical data.
The control method further comprises the following steps:
s4: if NMI interrupt signal is lost in the standby power process, the AC power supply state is polled and read at preset time intervals, and the AC power failure process is monitored again when the AC power supply state is the power failure state.
It can be appreciated that if the standby process can be monitored normally, whether the NMI interrupt signal is in place or not, once the NMI interrupt signal is lost, the AC power status must be polled for and read, and the AC power down process must be monitored again when it is determined that the status is a power down status.
It can be appreciated that after the power-up process is completed, the method further includes: the monitoring of the AC power down thread is exited. After the data protection of standby power is completed, the AC power-down process does not need to be monitored, so that the standby power-down process can be directly exited.
Further, after the standby power process is finished, the method further comprises:
and closing the main system and the standby power supply by using the Linux ram system.
It can be understood that the Linux ram system is utilized to actively close the main system, so that the situation of damage caused by sudden power failure of the main system can be avoided; the Linux ram system is utilized to actively turn off the standby power supply, so that the situation that the standby power supply cannot be turned off and the standby power supply is overdischarged and damaged due to the fact that the main system is powered down can be effectively prevented.
It can be understood that the Linux ram system should be started before use, that is, before the main system and the standby power supply are turned off by the Linux ram system, the Linux ram system further includes:
and calling kexec to start the linux ram system.

The control method takes the NMI interrupt signal as the premise, and polls and reads the AC power supply state when the NMI interrupt signal is lost, so that the control method has the advantage of quick sensing, can improve the efficiency of standby power protection, saves the power consumption of the standby power supply, and improves the reliability of data protection.

e) After AC loss, 2 PSUs are powered down, usually the PSUs support 3ms anti-shake, and then the add-in card is powered down after 6 ms.
f) Then PSU generates AC loss and sends the AC power-down signal to CPLD as interrupt;
g) The CPLD detects an AC power-down signal and switches the power supply mode to BBU power supply;
h) The CPLD sets an AC power-down signal and then triggers an NMI interrupt signal;
i) wdk drives and receives NMI interrupt signals sent by CPLD, triggers wdk interrupt processing functions in driving;
j) The interrupt processing function reads the AC power supply state in the GPIO, and sends out an AC_LOSS signal after confirming the AC power supply state as the power-down state AC LOSS so as to wake up a service_main monitoring AC power-down thread, namely an AC LOSS thread;
k) Service_main enters a standby power process;
l) if the MNI interrupt signal is lost in the standby power process, for example, the AC power supply state in the GPIO, that is, the ac_fail state, is read in every 50ms polling every preset time interval, and if the ac_fail state is an ac_loss signal, the service_main monitoring AC LOSS thread is awakened;
m) service_main terminates the IO_main process;
n) backing up the cached data hardendata in the memory to a hard disk;
o) the service_main monitoring process exits;
p) service_start starts executing the shutdown procedure:
q) service_start calls kexec to start the linux ram system;
r) closing the main system by the linux ram system;
s) the linux ram system turns off the standby power BBU.
