- Hi,
-
- we would like to DMA transfer data from a SGI machine to another
- machine (DEC LSI11). Both machines are connected by Ethernet and
- have Ethernet controllers.
-
- On the LSI11 there is no room for the overhead required by TCP/IP
- or UDP. The LSI11 initiates a DMA request (memory address, block
- size etc.) and expects the SGI machine to listen and to respond
- with a DMA transfer.
-
- QUESTION: What is to do or how must the SGI machine be configured
- to be able to receive the DMA request via the Ethernet
- and then in turn make the DMA transfer ?
-
- Any hint would be very much appreciated.
