DPC's and its schedulers in multiprocessor environment

Discussion in 'Windows Vista Drivers' started by Prakash Manannavar, May 27, 2010.

  1. Hi all,

    I have some queries on DPC's.


    1> In multiprocessor environment (Thinking as 2 processors), how many DPC
    queues will be there?

    2> In the same environment as above, How the DPC's get scheduled?

    Kindly let me know, Thanking you guys

  2. why does it matter? current implementations always queue DPCs to one
    processor, but that is not a contract you can rely on and must assume N DPCs
    can run concurrently
