Abstract
Certain aspects direct to systems and methods to perform service processor (SP) initiated data transaction with a host computer utilizing power off commands. In certain embodiments, the system includes a SP, which includes a processor, a non-volatile memory and a communication interface. The SP generates a first power off command for a data transaction purpose, and sends the first power off command to the host computer to initiate a data transaction. The OS, in response to the first power off command, calls an Advanced Configuration and Power Interface (ACPI) Machine Language (AML) code, which execute a system management interface (SMI) handler at the CPU to enter a system management mode (SMM). The SMI handler then sends a notification to the SP via the communication interface. In response to receiving the notification from the SMI handler, the SP starts performing the data transaction with the host computer.
