ACPI ID is used in the _HID (Hardware ID), _CID (Compatible ID) or
_SUB (Subsystem ID) objects as described in the ACPI Specification for
devices, that do not have a standard enumeration mechanism. The ACPI ID
consists of two parts: a vendor identifier followed by a product identifier.
Vendor IDs consist of 4 characters, each character being either an
uppercase letter (A-Z) or a numeral (0-9). The vendor ID SHOULD be
unique across the Industry and registered by the UEFI forum. For RVI
standard devices, RSCV is the vendor ID registered. Vendor-specific
devices can use an appropriate vendor ID registered for the manufacturer.
Product IDs are always four-character hexadecimal numbers (0-9 and A-F). The device manufacturer is responsible for assigning this identifier to each product model.
This document contains the canonical list of ACPI IDs for the namespace devices that adhere to the RVI specifications. The RVI task groups may make pull requests against this repository to request the allocation of ACPI ID for any new device.
