What about the 600 MB limit ?
Lads - please stop pushing new bindings until there's a solution in
place for that.
Either codify the block Daniel has - which TBH I think is wrong because
it prohibits allocation < 600 MB for pixel buffers.
Or restrict the IOVAs in the driver _or_ via syntax magic in DT.
Either way we know this is buggy !
