Going back to [1], is memlat-over-scmi not enough to give us good numbers
without OS intervention? Does probing bwmon and making some decisions in
Linux actually help here?
Memlat and bwmon are meant to cover to different use cases. Though
they have a big overlap on when they get triggered bwmon is specifically
meant to address cases where band-width aggregation is required (meaning
if other peripherals already have a avg bw vote on active LLCC/DDR, the
vote from bwmon would be an additional request on top of that). However
to make use of this we should vote for avg-kbps in addition to peak from
icc-bwmon driver which we don't currently do (Shiv was planning on
sending a fix for it).
