dma from pci device
Posts: n/a
      03-17-2005, 06:01 AM

I need to know if my pci device with dma
capabilities can read-modify-write in one cycle. Whether such a things
at all exists ?

I want to read host main memory from a pci device without the operating
system modifying it till I am done, in other words I need some form of
mutual exclusion.

Is this at all possible ?

your help is greatly appreciated!
