Problem Description:
Customer is running probevue scripts to capture rare LPM
hang on the frames and this is causing DR CPU ADD failures.
probevue thread is sleeping holding tbm_consumer_elock
and that caused probevue DR handler to fail.
From Defect 700584
Just wanted to document the fix here and the expectations so that
if we run into DR issues later we know where to look and that to do.
The trace buffer manager and DR need to be serialized for there
situations:
1. Session start and DR and this is done by the etrc_lock.
2. trace buffer manager timer handler and DR and this is done by
the etrc_timer_lock.
3. This was the issue that was being seen in 61F ie trace consumer and DR.
To resolve the third we try to acquire all the consumer locks in the DR handler and allow DR
only if all the consumer locks are acquired and fail DR otherwise.
