Advanced Programmable Corrected Memory Error Threshold Event Flags 2. Corrected Memory Error Count at Event 3. Memory Event Sub-Type The format of component identifier has changed (CXL spec 3.1 section 8.2.9.2.1 Table 8-44). Update the general media event record and general media trace event for the above spec changes. The new fields are inserted in logical places.
