DMA is possible for SCSI and floppy already. It is possible to fake DMA


But currently it blocks, doesn't it?. I remember having looked at the
code long ago, and I think there was not much missing.


The kernel is full of #ifdef NONBLOCKING_DMA, does that matter here?
Yes it does. There is kernel infrastructure for DMA, and it is quite simple, so writing drivers that use them is no big challenge.
