Currently trace events are generated for: - Start and stop of DAPM processing - Start and stop of bias level changes - Power decisions for widgets - Widget event execution start and stop giving some view as to what is happening and where latencies occur. Actual changes in widget power can be seen via the register write trace in soc-core. Signed-off-by: Mark Brown Acked-by: Liam Girdwood --- Reading git-diff-tree failed
