That's good. However, don't forget that the scsi stuff in the
magnum depends on the DMA page tables. I suggest to use global
in/out buffers first, and when the driver seems to work to
choose a better page allocation scheme. Otherwise you'll end
up in a halfway working driver like the Sonic (which I claim
to be responsible for :-( ).
To get an idea, take a look at the floppy driver. It uses
statically allocated track buffers and DMA page tables.
Cheers,
Andy
