The following patch set adds NXP DPAA2 HW based eventdev
implementation to the next-eventdev tree.
The patchset consists of the following:
- DPCON support required by DPAA2 eventdev
- DPCI support in fslmc bus
- Interrupt support in QBMAN
- Implemetation of eventdev API's for DPAA2
- Documentation of DPAA2 eventdev PMD
Hemant Agrawal (2):
bus/fslmc: generic framework for mc object creation
bus/fslmc: export qbman dqrr funcs for eventdev usages
Nipun Gupta (18):
event/dpaa2: add basic build infrastructure
bus/fslmc: integrating dpio and dpbp to object framework
bus/fslmc: adding basic dpcon support
event/dpaa2: register dpcon as dpaa2 device for bus scan
bus/fslmc: adding basic dpci support
bus/fslmc: register dpci as dpaa2 device for bus scan
bus/fslmc: adding cpu support in stashing config
event/dpaa2: add initialization of event device
bus/fslmc: add support for static dequeue from portal
event/dpaa2: add configuration functions
bus/fslmc: support enqueue with multiple enqueue descriptors
bus/fslmc: add callback per queue to enable
bus/fslmc: change func argument to const to avoid warning
event/dpaa2: add enqueue and dequeue functionality
fslmc/bus: add interrupt enabling routine
bus/fslmc: enable portal interrupt handling
event/dpaa2: handle timeout using interrupts in dequeue
doc: add NXP DPAA2 EVENTDEV details

There are muliple help mc object, which are not an independent
device, but they are required for dpaa2 based devices.
This framework allows registration and handling of all such
mc devices.

This patch removes the existing static call for dpio and dpbp
create and add them to object registration framework.
This patch also changes the vfio mc object processing to use
the framework.

Dequeue from event device needs to process the event on
the basis of the hardware queue from which it is dequeued.
A callback is added into dpaa2_queue structure, to enable
event dequeue functionality to call that processing routine.

qbman_get_dqrr_idx() API is required with constant dqrr entry
in the eventdev driver. Also, this routine is not updating the
dqrr. So, this patch updates its input argument to a const type.

This patch adds support for interrupt handling on the event port.
These interrupts facilitates managing of timeout ticks in the
event dequeue functions.

+
+NXP DPAA2 Eventdev Driver
+==================================
+
+The dpaa2 eventdev is an implementation of the eventdev API, that provides a
+wide range of the eventdev features. The eventdev relies on a dpaa2 hw to
+perform event scheduling.
+
+More information can be found at `NXP Official Website
+<http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/qoriq-arm-processors:QORIQ-ARM>`_.
+
+Features
+--------
+
+The DPAA2 EVENTDEV implements many features in the eventdev API;
+
+- Hardware based event scheduler
+- 8 event ports
+- 8 event queues
+- Parallel flows
+- Atomic flows
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2080A/LS2040A
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 EVENTDEV on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/aarch64-linux-gnu>`_.
+
+2. **Linux Kernel**
+
+ It can be obtained from `NXP's Github hosting <https://github.com/qoriq-open-source/linux>`_.
+
+3. **Rootfile system**
+
+ Any *aarch64* supporting filesystem can be used. For example,
+ Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained
+ from `here <http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.1-base-arm64.tar.gz>`_.
+
+As an alternative method, DPAA2 EVENTDEV can also be executed using images provided
+as part of SDK from NXP. The SDK includes all the above prerequisites necessary
+to bring up a DPAA2 board.
+
+The following dependencies are not part of DPDK and must be installed
+separately:
+
+- **NXP Linux SDK**
+
+ NXP Linux software development kit (SDK) includes support for family
+ of QorIQ® ARM-Architecture-based system on chip (SoC) processors
+ and corresponding boards.
+
+ It includes the Linux board support packages (BSPs) for NXP SoCs,
+ a fully operational tool chain, kernel and board specific modules.
+
+ SDK and related information can be obtained from: `NXP QorIQ SDK <http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-processors:SDKLINUX>`_.
+
+- **DPDK Helper Scripts**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ as provided in the DPDK helper repository.
+
+ `DPDK Helper Scripts <https://github.com/qoriq-open-source/dpdk-helper>`_.
+
+Currently supported by DPDK:
+
+- NXP SDK **2.0+**.
+- MC Firmware version **10.0.0** and higher.
+- Supported architectures: **arm64 LE**.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+.. note::
+
+ Some part of fslmc bus code (mc flib - object library) routines are
+ dual licensed (BSD & GPLv2).
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+Please note that enabling debugging options may affect system performance.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_event`` driver.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV_DEBUG`` (default ``n``)
+
+ Toggle display of generic debugging messages
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 EVENTDEV PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+ cd <DPDK-source-directory>
+ make config T=arm64-dpaa2-linuxapp-gcc install
+
+Limitations
+-----------
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.
+
+Port-core binding
+~~~~~~~~~~~~~~~~~
+
+DPAA2 EVENTDEV driver requires event port 'x' to be used on core 'x'.

Thomas,
Is it OK to take bus/ related changes through eventdev-next?

If RTE_EVENT_QUEUE_CFG_ALL_TYPES is supported then add
RTE_EVENT_DEV_CAP_QUEUE_ALL_TYPES in rte_event_dev_info.event_dev_cap

Based on the documentation, it looks like ORDERED sched type is not
supported. If so, return an error when queue config request is
RTE_EVENT_QUEUE_CFG_ORDERED_ONLY.
On the same lines, default_queue_setup() returns
RTE_EVENT_QUEUE_CFG_ALL_TYPES as default value. If ORDERED sched type
is not supported then I think, RTE_EVENT_QUEUE_CFG_ALL_TYPES
can not be used as default or configured.

Is it a HW limitation? or Is it like, only one port can connect to one
lcore. If it latter, then I think, you can have physical port to virtual
port translation in slow path as ports are enumerated as 0 to N. lcore
id can be anything.

Yes if it is only related to eventdev.
We must take care that these changes won't be needed by next-net,
otherwise it must go in master branch.

Thank you for the review.
Regarding this I check most of the c files in DPDK and do not see that alphabetical
being maintained in the header file inclusions. Are you suggesting to have an alphabetical
order here across all inclusions of rte* as well as gcc standard header files (combined) or
to have them ordered separately?

Yes, Right now we are supporting only parallel and atomic queues and waiting
for our MC firmware to have support for ordered queues in case of enqueue

Appreciate your suggestion, but right now our event driver limits this.
This is because core needs to be known at event port setup.
As event port setup is done at initialization time, we need to have this limitation.
We are having discussions to somehow do away with this.
