Background
The power supply Powerbutton key plays a significant role in any electronic consumer product, and the power supply key is required to realize rapid operation in startup, shutdown and restart of equipment, and is particularly important in the field of servers of data centers. More than 90% of the power key functions of the servers of the global data center are defaulted to realize the startup and shutdown actions of the servers through a GPD3_ PWRBTN _ N signal of a PCH, when the power key is pressed down for a short time, namely the startup and shutdown actions are triggered, when the system is powered down, SCI interruption triggers the system kernel to perform soft shutdown actions, and when the power key is pressed down for a long time, namely the key pressing time is more than 4S, the hardware shutdown actions are triggered. When the server is in a non-operating System, a power key is pressed for a short time to trigger a System shutdown function, and the triggering mechanism at the moment triggers an SMI (System Management Interrupt) Interrupt mechanism by the BIOS according to a GPD3_ PWRBTN _ N signal, wherein the SMI Interrupt mechanism adopts a hardware Interrupt mechanism principle that the power key generates a hardware Interrupt to trigger an SMM program (System Management Mode) of the BIOS internal SMI Interrupt when pressed for a short time, the CPU needs to enter the System Management Mode in advance when the SMM program is executed, a specific operation flow is that the CPU needs a memory area SMRAM, the value of the register is stored in the SMRAM before the CPU enters the SMM, the program is jumped to SMI ENY POINT to be executed, the RSM instruction is jumped back to the original place to be executed after the processing is finished, and the value of the CPU register is restored.
