From 98b6926562d9ccdbca69de9a0e0bf4f90d7f1326 Mon Sep 17 00:00:00 2001 From: Alison Schofield Date: Tue, 18 Apr 2023 20:26:28 -0700 Subject: cxl/memdev: Trace inject and clear poison as cxl_poison events The cxl_poison trace event allows users to view the history of poison list reads. With the addition of inject and clear poison capabilities, users will expect similar tracing. Add trace types 'Inject' and 'Clear' to the cxl_poison trace_event and trace successful operations only. If the driver finds that the DPA being injected or cleared of poison is mapped in a region, that region info is included in the cxl_poison trace event. Region reconfigurations can make this extra info useless if the debug operations are not carefully managed.
