Mark Brown de02d0786d ASoC: Trace and collect statistics for DAPM graph walking ... One of the longest standing areas for improvement in ASoC has been the DAPM algorithm - it repeats the same checks many times whenever it is run and makes no effort to limit the areas of the graph it checks meaning we do an awful lot of walks over the full graph. This has never mattered too much as the size of the graph has generally been small in relation to the size of the devices supported and the speed of CPUs but it is annoying. In preparation for work on improving this insert a trace point after the graph walk has been done. This gives us specific timing information for the walk, and in order to give quantifiable (non-benchmark) numbers also count every time we check a link or check the power for a widget and report those numbers. Substantial changes in the algorithm may require tweaks to the stats but they should be useful for simpler things.
