[dpdk-dev] [PATCHv8 00/46] NXP DPAA2 PMD

[Hemant Agrawal]

The patch series adds NXP’s QorIQ-Layerscape DPAA2 Architecture based
fsl-mc bus driver and network SoC PMD.  This version of the driver
supports NXP LS208xA, LS204xA and LS108x families Network SoCs.

DPAA2, or Data Path Acceleration Architecture, is a hardware architecture
designed for high-speed network packet processing. It uses a bus name
‘fsl-mc’, part of Linux Kernel Staging tree [1], for resource management.

A brief description of architecture is given below; detailed description
is part of the documentation in the patches itself.

DPAA2 contains hardware component called the Management Complex (or MC).
It manages the DPAA2 hardware resources.  The MC provides an object-based
abstraction for software drivers to use the DPAA2 hardware.

Some of the key objects are:
    - DPNI, which refers to the network interface object.
    - DPBP, which refers to HW based memory pool object
    - DPIO, refers to processing context for accessing QBMAN

Besides the MC, DPAA2 also includes a Hardware based Queue and Buffer Manager
called QBMAN. Prime responsibility of QBMAN is to allow lockless access to
software/user-space to the queues and buffers implemented in the hardware.

The patch series could be logically structured into following sub-areas:
1. Make file changes for crc in armv8 core machine type and driver dependency
2. Indroducing fsl-mc bus as rte_bus, it's componenets.
3. Introducing dpaa2 pmd driver
4. Introducing dpaa2 mempool 
5. Support for DPAA2 Ethernet Device (ethdev)
6. Additional functionality in DPAA2 ethdev.

The following design decisions are made during development:

1. DPAA2 implements a new bus called "fsl-mc" and some common accelerator drivers.
   These drivers will be shared with dpaa2 based crypto drivers.

2. DPAA2 implements the HW mempool offload with DPBP object.
 - The new pool is being configured using compile time option and pool name
   as "dpaa2".

3. It maintains per lcore DPIO objects and affine the DPIO instance to the
   processing threads accessing the QBMAN HW.

Prerequisites:
 - For running the PMD, NXP's SoC (board) is required.
   Information about obtaining relevant software is available in the docs
   as part of the patch.

Future Changes/Caveats:

1. VFIO code for fsl-mc bus is different than eal-vfio code for pci bus.
   This need to be re-worked to make possible re-use of the existing code.
