Data Fields
uint64_t	entries
	Total number of mark_enter calls for this region.
uint64_t	exits
	Total number of mark_exit calls for this region.
uint64_t	total_time_us
	Sum of (exit - enter) over all closed pairs, microseconds.
uint64_t	last_enter_us
	Timestamp of the most recent unmatched mark_enter.
bool	is_open
	true if a mark_enter is awaiting a mark_exit.

Detailed Description

Per-region accumulator returned by ra8_power_profile_get_stats.

Captures everything the profiler tracks per region: how many enter/exit pairs were observed, total time accumulated, and the timestamp / count of any unmatched enter events still in-flight.

Invariant

entries >= exits. The difference is the number of currently-open regions for that ID.

total_time_us only counts fully-closed regions (enter+exit pairs); open regions do not contribute.
