Relative Global Device Numbers

SOF assigns each discovered hardware device a sequential six-digit hexadecimal relative global device number. Think of the relative global device number as a shorthand version of the DEVID, but they bear no relation to each other. The relative global device number is included in GLOBAL SOF command displays, and may be used to specify a device on GLOBAL SOF commands (with leading zeros not required).

Note: Assigned relative global device numbers are not static. They are dynamically reassigned whenever devices are dynamically added to or removed from the shared I/O configuration.
