ACPI 4.0 spec adds the ACPI IPMI opregion, which means that the ACPI AML code can also communicate with the BMC controller. This is to install the ACPI IPMI opregion and enable the ACPI to access the BMC controller through the IPMI message. It will create IPMI user interface for every IPMI device detected in ACPI namespace and install the corresponding IPMI opregion space handler. Then it can enable ACPI to access the BMC controller through the IPMI message. The following describes how to process the IPMI request in IPMI space handler: 1. format the IPMI message based on the request in AML code. IPMI system address. Now the address type is SYSTEM_INTERFACE_ADDR_TYPE IPMI net function & command IPMI message payload 2. send the IPMI message by using the function of ipmi_request_settime 3. wait for the completion of IPMI message. It can be done in different routes: One is in handled in IPMI user recv callback function. Another is handled in timeout function. 4. format the IPMI response and return it to ACPI AML code. At the same time it also addes the module dependency. The ACPI IPMI opregion will depend on the IPMI subsystem.
