Yes. Although I'd just name it kernel/dma/pool.c and CONFIG_DMA_COHERENT_POOL or so, as I plan to reuse the code for architectures that just preallocate all coherent memory at boot time as well. > I think that's what you mean by splitting the pool from remapping, > otherwise we still have a full CONFIG_DMA_REMAP dependency here.

Yes, that is exactly what I meant. _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
