- Promote EVENT_CP_CREATE / EVENT_CP_DESTROY from internal to release
for content protection session lifecycle visibility in ETW.
- Add EVENT_CP_FW_ERROR at HW security FW IoMessage error path,
capturing all FW command failures (CommandId / FW status code /
API version / stream id).
- Add EVENT_CP_HUC_AUTH_FAIL at HuC authentication check failure paths.
- New events fire only on error or per session create/destroy,
zero overhead on success path. Verified on MTL with HCLR secure
decode test: session create/destroy events all appear in release
driver ETW trace.
- KeyExchange and legacy HuC PPED events are intentionally NOT promoted
to release: the OS DDI trace layer already exposes the corresponding
events, so a driver-side release event would duplicate data without
adding diagnostic value.
