Overview
+========
The Dell Systems Management Base Driver provides a sysfs interface for
systems management software such as Dell OpenManage to perform system
System Management Interrupt
+===========================
On some Dell systems, systems management software must access certain
management information via a system management interrupt (SMI). The SMI data
buffer is required for the SMI. The driver maintains the memory required for
the SMI and provides a way for the application to generate the SMI.
The driver creates the following sysfs entries for systems management
-software to perform these system management interrupts:
+software to perform these system management interrupts::
-/sys/devices/platform/dcdbas/smi_data
-/sys/devices/platform/dcdbas/smi_data_buf_phys_addr
-/sys/devices/platform/dcdbas/smi_data_buf_size
-/sys/devices/platform/dcdbas/smi_request

+ /sys/devices/platform/dcdbas/smi_data_buf_phys_addr
+ /sys/devices/platform/dcdbas/smi_data_buf_size
+ /sys/devices/platform/dcdbas/smi_request
Systems management software must perform the following steps to execute
a SMI using this driver:
Host Control Action
+===================
Dell OpenManage supports a host control feature that allows the administrator
to perform a power cycle or power off of the system after the OS has finished
Host Control SMI Type

The following table shows the value to write to host_control_smi_type to
perform a power cycle or power off host control action:
