hverkuil: am I correct assuming there is no API for userspace to control buffer allocation coherency policies ?
I see set_queue_coherency() being available for drivers
but I don't see a way for userspace to control that
I presume it's by design...
ah sorry, I just discovered allow_cache_hints and V4L2_MEMORY_FLAG_NON_COHERENT
hverkuil: a question for you in [PATCH] media: rkisp1: allow non-coherent video capture buffers
I assumed you were in cc, but it actually wasn't the case, sorry
