Description:
|
|
The file contains a Slot-unique ID which provided by the _SUN
|
|
method in the ACPI namespace. The value is written in Advanced
|
|
Configuration and Power Interface Specification as follows:
|
|
|
|
"The _SUN value is required to be unique among the slots of
|
|
the same type. It is also recommended that this number match
|
|
the slot number printed on the physical slot whenever possible."
|
|
|
|
So reading the sysfs file, we can identify a physical position
|
|
of the slot in the system.
