question about receiving data by 6678 srio DIO under linux

Murat Tekalp

Hi, all:

  I connect 2 6678 evm boards with a backplane. Both of the boards run

linux-c6x. Now one board can successfully write and read data with the

other board by means of SRIO DirectIO.

  But I still have doubt about the source codes:

   I can find codes about sending DIO data. But on the receiving side, I can't

    find codes which is in charge of receiving data by means of DirectIO.

    I can only know the address where the linux place the received data.

    Can anyone tell me? 

    Thanks!
