Subject: [PATCH 13/13] rasdaemon: ras-mc-ctl: Update logging of CXL memory module data to align with CXL spec rev 3.1
From: Shiju Jose <shiju.jose@...wei.com>
CXL spec 3.1 section 8.2.9.2.1.3 Table 8-47, Memory Module Event Record
has updated with following new fields and new info for Device Event Type
and Device Health Information fields.
1. Validity Flags
2. Component Identifier
3. Device Event Sub-Type
This update modifies ras-mc-ctl to parse and log CXL memory module event
data stored in the RAS SQLite database table, reflecting the
specification changes introduced in revision 3.1.
Example output,
./util/ras-mc-ctl --errors
...
CXL memory module events:
