Is this fixing some particular case you could note in the commit message? As is, it makes me think that we should be using a notifier for when the parent clock (that's the one I assume you're talking about being dynamic) changes. But maybe you're working around a variable VPU clock being set by the firmware, because we don't have a notifier for it?
I'm a bit worried because I think this is going to be pretty expensive to be doing per transfer. [unhandled content-type:application/pgp-signature] | |
