Other Pieces ------------ +Get the detailed info related with the IPMI device +-------------------------------------------------- + +Some users need more detailed information about a device, like where +the address came from or the raw base device for the IPMI interface. +You can use the IPMI smi_watcher to catch the IPMI interfaces as they +come or go, and to grab the information, you can use the function +ipmi_get_smi_info(), which returns the following structure: + +struct ipmi_smi_info { + enum ipmi_addr_src addr_src; + struct device *dev; + union { + struct { + void *acpi_handle; + } acpi_info; + } addr_info; +}; + +Currently special info for only for SI_ACPI address sources is +returned.
