Re: [alsa-devel] [RFC] dice: simplifying address registration

Currently Dice driver keeps address ranges for each unit instance. But there's a way to reuse the same address range.

This requires an additional check for the packet's source node, which is essentially a duplicate of the core's address lookup code.

I think this idea can simplify driver probe processing

Yes, but that code is just moved to the module load processing.

and save resources of host controller.

When using multiple DICE devices, this saves four bytes of FireWire address space per card, out of the total address space of 2^48 bytes. Or what other resources do you mean?
