| 17 | ===================================================================== | ||
| 18 | Overview | ||
| 19 | |||
| 20 | DESCRIPTION | ||
| 21 | |||
| 22 | SEC 4 h/w can process requests from 2 types of sources. | ||
| 23 | 1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4). | ||
| 24 | 2. Job Rings (HW interface between cores & SEC 4 registers). | ||
| 25 | |||
| 26 | High Speed Data Path Configuration: | ||
| 27 | |||
| 28 | HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts | ||
| 29 | such as the P4080. The number of simultaneous dequeues the QI can make is | ||
| 30 | equal to the number of Descriptor Controller (DECO) engines in a particular | ||
| 31 | SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus | ||
| 32 | dequeue from 5 subportals simultaneously. | ||
| 33 | |||
| 34 | Job Ring Data Path Configuration: | ||
| 35 | |||
| 36 | Each JR is located on a separate 4k page, they may (or may not) be made visible | ||
| 37 | in the memory partition devoted to a particular core. The P4080 has 4 JRs, so | ||
| 38 | up to 4 JRs can be configured; and all 4 JRs process requests in parallel. | ||
| 39 | |||

| 41 | SEC 4 Node | ||
| 42 | |||
| 43 | Description | ||
| 44 | |||
| 45 | Node defines the base address of the SEC 4 block. | ||
| 46 | This block specifies the address range of all global | ||
| 47 | configuration registers for the SEC 4 block. It | ||
| 48 | also receives interrupts from the Run Time Integrity Check | ||
| 49 | (RTIC) function within the SEC 4 block. | ||
