+Get the detailed info related with the IPMI device
+--------
+The IPMI smi_watcher will be used to catch the IPMI interface as they come or go.
+In order to communicate with the correct IPMI device, it should be confirmed
+ whether it is what we wanted especially on the system with multiple IPMI
+devices. But the new_smi callback function of smi_watcher provides very
+limited info(only the interface number and dev pointer) and there is no
+detailed info about the low level interface. For example: which mechansim
+registers the IPMI interface(ACPI, PCI, DMI and so on).
+ The function of ipmi_get_smi_info is added to get the
+detailed info of IPMI device. The following is the struct definition of
+ipmi_smi_info(Now only ACPI info is defined. If the info is required for
+other IPMI device type, please add it) .
+ struct ipmi_smi_info{
+ enum ipmi_addr_src addr_src;
+ struct device *dev;
+ union {
+ /*
+ * Now only SI_ACPI info is provided. If the info is required
+ * for other type, please add it
+ */
+#ifdef CONFIG_ACPI
+ struct {
+ void *acpi_handle;
+ } acpi_info;
+#endif
+ } smi_info;
+};
+
+ The following is the definition of ipmi_get_smi_info.
+ extern int ipmi_get_smi_info(int if_num, enum ipmi_addr_src type,
+ struct ipmi_smi_info **data);
+ It is noted that the returned smi_data is not the dynamically
+allocated memory. It is only the pointer of the corresponding info stored
+in IPMI device. In such case the caller don't try to free the corresponding
+memory.
