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.
