DPAA Ethernet Overview
|
||||
======================
|
||||
|
||||
DPAA stands for Data Path Acceleration Architecture and it is a
|
||||
set of networking acceleration IPs that are available on several
|
||||
generations of SoCs, both on PowerPC and ARM64.
|
||||
|
||||
The Freescale DPAA architecture consists of a series of hardware blocks
|
||||
that support Ethernet connectivity. The Ethernet driver depends upon the
|
||||
following drivers in the Linux kernel:
|
||||
|
||||
- Peripheral Access Memory Unit (PAMU) (* needed only for PPC platforms)
|
||||
drivers/iommu/fsl_*
|
||||
- Frame Manager (FMan)
|
||||
drivers/net/ethernet/freescale/fman
|
||||
- Queue Manager (QMan), Buffer Manager (BMan)
|
||||

||||

||||

Configuring DPAA Ethernet in your kernel
|
||||
========================================
|
||||
|
||||
To enable the DPAA Ethernet driver, the following Kconfig options are required:
|
||||
|
||||
# common for arch/arm64 and arch/powerpc platforms
|
||||
CONFIG_FSL_DPAA=y
|
||||
CONFIG_FSL_FMAN=y
|
||||
CONFIG_FSL_DPAA_ETH=y
|
||||
CONFIG_FSL_XGMAC_MDIO=y
|
||||
|
||||
# for arch/powerpc only
|
||||
CONFIG_FSL_PAMU=y
|
||||
|
||||
# common options needed for the PHYs used on the RDBs
|
||||
CONFIG_VITESSE_PHY=y
|
||||
CONFIG_REALTEK_PHY=y
|
||||
CONFIG_AQUANTIA_PHY=y
|
||||
|
||||
DPAA Ethernet Frame Processing
|
||||
==============================
|
||||
|
||||
On Rx, buffers for the incoming frames are retrieved from one of the three
|
||||
existing buffers pools. The driver initializes and seeds these, each with
|
||||
buffers of different sizes: 1KB, 2KB and 4KB.
|
||||
|
||||
On Tx, all transmitted frames are returned to the driver through Tx
|
||||
confirmation frame queues. The driver is then responsible for freeing the
|
||||
buffers. In order to do this properly, a backpointer is added to the buffer
|
||||
before transmission that points to the skb. When the buffer returns to the
|
||||
driver on a confirmation FQ, the skb can be correctly consumed.
|
||||
|
||||
DPAA Ethernet Features
|
||||
======================
|
||||
|
||||
Currently the DPAA Ethernet driver enables the basic features required for
|
||||
a Linux Ethernet driver. The support for advanced features will be added
|
||||
gradually.
|
||||
|
||||
The driver has Rx and Tx checksum offloading for UDP and TCP. Currently the Rx
|
||||
checksum offload feature is enabled by default and cannot be controlled through
|
||||
ethtool.
|
||||
|
||||
The driver has support for multiple prioritized Tx traffic classes. Priorities
|
||||
range from 0 (lowest) to 3 (highest). These are mapped to HW workqueues with
|
||||
strict priority levels. Each traffic class contains NR_CPU TX queues. By
|
||||
default, only one traffic class is enabled and the lowest priority Tx queues
|
||||
are used. Higher priority traffic classes can be enabled with the mqprio
|
||||
qdisc. For example, all four traffic classes are enabled on an interface with
|
||||
the following command. Furthermore, skb priority levels are mapped to traffic
|
||||
classes as follows:
|
||||
|
||||
* priorities 0 to 3 - traffic class 0 (low priority)
|
||||
* priorities 4 to 7 - traffic class 1 (medium-low priority)
|
||||
* priorities 8 to 11 - traffic class 2 (medium-high priority)
|
||||
* priorities 12 to 15 - traffic class 3 (high priority)
|
||||
|
||||
tc qdisc add dev <int> root handle 1: \
|
||||
mqprio num_tc 4 map 0 0 0 0 1 1 1 1 2 2 2 2 3 3 3 3 hw 1

Debugging
|
||||
=========
|
||||
|
||||
The following statistics are exported for each interface through ethtool:
|
||||
|
||||
- interrupt count per CPU
|
||||
- Rx packets count per CPU
|
||||
- Tx packets count per CPU
|
||||
- Tx confirmed packets count per CPU
|
||||
- Tx S/G frames count per CPU
|
||||
- Tx error count per CPU
|
||||
- Rx error count per CPU
|
||||
- Rx error count per type
|
||||
- congestion related statistics:
|
||||
- congestion status
|
||||
- time spent in congestion
|
||||
- number of time the device entered congestion
|
||||
- dropped packets count per cause
|
||||
|
||||
The driver also exports the following information in sysfs:
|
||||
|
||||
- the FQ IDs for each FQ type
|
||||
/sys/devices/platform/dpaa-ethernet.0/net/<int>/fqids
|
||||
|
||||
- the IDs of the buffer pools in use
