Can anyone suggest driver source code (or documenation) that would be helpful in writing a driver that uses DMA on a Sparc (Ultra 10, etc.) ?
I am trying to find a overview of the operations required on the various types of memory accessable from the driver. Is it possible to resolve a user virtual address to a physical address, lock that physical address, perform DMA between the device and the locked physcial address and then unlock the physical memory ?
