[comp.unix.wizards] adding ordinary VME bus memory to a Sun

ndd@duke.cs.duke.edu (Ned Danieley) (09/09/87)

We would like to put some amount of memory (~4M) on a Sun VME bus
and use it as part of a data acquisition system. This means that we
would want to DMA from a drv11-w equivalent card on the bus into
the extra memory. It looks to me as if this could be done if we had
a generic frame-buffer type driver and then did a valloc and a mmap
so we could read(2) into the buffer. Does this sound right? Has
anyone done such a thing? Any help would be appreciated.
