[PATCH 17/21] iwlwifi: dbg_ini: remove apply point, switch to time point API

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shahar S Matityahu <shahar.s.matityahu@xxxxxxxxx>

Remove the "apply points" mechanism as preparation for the changed
debug API where this is now a "time point" instead. Use a new API
across the code at the trigger points ("time points"), but don't
yet implement it since that requires some more preparation.
