-Overview
-
-DESCRIPTION
-
-SEC 4 h/w can process requests from 2 types of sources.
-1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4).
-2. Job Rings (HW interface between cores & SEC 4 registers).
-
-High Speed Data Path Configuration:
-
-HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts
-such as the P4080. The number of simultaneous dequeues the QI can make is
-equal to the number of Descriptor Controller (DECO) engines in a particular
-SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus
-dequeue from 5 subportals simultaneously.
-
-Job Ring Data Path Configuration:
-
-Each JR is located on a separate 4k page, they may (or may not) be made visible
-in the memory partition devoted to a particular core. The P4080 has 4 JRs, so
-up to 4 JRs can be configured; and all 4 JRs process requests in parallel.
