    What sizes of data payload are supported in PCIe TLP when using DirectGMA?

    evoliptic

      Hello there,

       

      In the transport layer packet of PCIe, there is a sub-part dedicated to data, which we call here payload (the schema of TLP we have may be found on the first page of that paper : http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=7111377 ). Its size could vary however there is a standard size of 128 bytes, supported by all hardware normally.

       

      I would so like to know if the GPU can handle different sizes of data in the PCIe TLP?

       

      thanks in advance,

      nicolas
