  • 1.  ASIC to CPU punt

    Posted 06-04-2019 07:08 AM
    Hi,

    I would like to know if DMA is done for punting packets from ASIC (e.g Trident/Dune chip)
    to CPU. Is there any other mechanism other than DMA for copying the packet to the route processor CPU memory.
    Any reference to internal architecture doc or web links to understand the packet flow would be of great help.

    Thank you
