The patch series adds NXP’s QorIQ-Layerscape DPAA2 Architecture based
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 [2], 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. (Patch 0001) DPAA2 Architecture overview document
2. (Patches 0002-0007) Common dpaa2 hw accelerator drivers for MC and QBMAN.
3. (Patch 0008) Enabling crc in armv8 core machine type
4. (Patch 0009) Adding rte_device in rte_eth_dev
5. (Patches 0010-0013) introduce DPAA2 bus and VFIO routines
6. (Patches 0014-0017) dpio and dpbp object drivers
7. (Patches 0018-0027) Support for DPAA2 Ethernet Device (ethdev)
8. (Patches 0028-0032) Additional functionality in DPAA2 ethdev.
The following design decisions are made during development:
1. DPAA2 implements a new bus called "dpaa2" and some common accelerator drivers.
These drivers will be shared with dpaa2 based crypto drivers.
- For this, patch series from Shreyansh [1] has been used for creating a
bus handler.
- For the purpose of this bus, rte_dpaa2_device/rte_dpaa2_driver might
also be required but they are not part of the first patch series.
Currently, rte_device/driver are being directly used as a PoC.
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) and SDK (software/BSP) is required.
Information about obtaining relevant software is available in the docs
as part of the patch.
- At present the series has limited support for Ethernet functions. But,
more functionality would be made available in a phased manner.
- This PMD has been validated over the Bus Model [1] and SoC Patchset [3]
