[dpdk-dev] [PATCH 1/8] net/mvpp2: initialize ppio only once

[Tomasz Duszynski]

From: Natalie Samsonov <nsamsono@marvell.com>

This changes stop/start/configure behavior due to issue in MUSDK
library itself.  From now on, ppio can be reconfigured only after interface
is closed.

[dpdk-dev] [PATCH 4/8] net/mvpp2: change default policer configuration

[Tomasz Duszynski]

Change QoS configuration file syntax for port's default policer
setup.

Since default policer configuration is performed before
any other policer configuration we can pick a default id.

This simplifies default policer configuration since user
no longer has to choose ids from range [0, PP2_CLS_PLCR_NUM].

Explicitly document values for rate_limit_enable field.

[dpdk-dev] [PATCH 5/8] net/mvpp2: add init and deinit to flow

[Tomasz Duszynski]

Add init and deinit functionality to flow implementation.

Init puts structures used by flow in a sane sate.
Deinit deallocates all resources used by flow.

[dpdk-dev] [PATCH 7/8] net/mvpp2: detach tx_qos from rx cls/qos config

[Tomasz Duszynski]

From: Yuval Caduri <cyuval@marvell.com>

Functional change:
Open receive cls/qos related features, only if the
config file contains an rx_related configuration entry.
This allows to configure tx_related entries, w/o unintentionally
opening rx cls/qos.

Code:
'use_global_defaults' is by default set to '1'.
Only if an rx_related entry was configured, it is updated to '0'.
rx cls/qos is performed only if 'use_global_defaults' is '0'.
Default TC configuration is now only mandatory when
'use_global_defaults' is '0'.

[dpdk-dev] [PATCH v2 01/12] net/mvpp2: initialize ppio only once

[Tomasz Duszynski]

From: Natalie Samsonov <nsamsono@marvell.com>

This changes stop/start/configure behavior due to issue in MUSDK
library itself.  From now on, ppio can be reconfigured only after interface
is closed.

[dpdk-dev] [PATCH v2 04/12] net/mvpp2: change default policer configuration

[Tomasz Duszynski]

Change QoS configuration file syntax for port's default policer
setup.

Since default policer configuration is performed before
any other policer configuration we can pick a default id.

This simplifies default policer configuration since user
no longer has to choose ids from range [0, PP2_CLS_PLCR_NUM].

Explicitly document values for rate_limit_enable field.

[dpdk-dev] [PATCH v2 05/12] net/mvpp2: add init and deinit to flow

[Tomasz Duszynski]

Add init and deinit functionality to flow implementation.

Init puts structures used by flow in a sane sate.
Deinit deallocates all resources used by flow.

[dpdk-dev] [PATCH v2 07/12] net/mvpp2: detach tx_qos from rx cls/qos config

[Tomasz Duszynski]

From: Yuval Caduri <cyuval@marvell.com>

Functional change:
Open receive cls/qos related features, only if the
config file contains an rx_related configuration entry.
This allows to configure tx_related entries, w/o unintentionally
opening rx cls/qos.

Code:
'use_global_defaults' is by default set to '1'.
Only if an rx_related entry was configured, it is updated to '0'.
rx cls/qos is performed only if 'use_global_defaults' is '0'.
Default TC configuration is now only mandatory when
'use_global_defaults' is '0'.

[dpdk-dev] [PATCH v2 09/12] net/mvpp2: align with MUSDK 18.09

[Tomasz Duszynski]

This patch introduces necessary changes required by MUSDK 18.09 library.

* As of MUSDK 18.09, pp2_cookie_t is no longer available. Now
  RX descriptor cookie is defined as plain u64 so existing cast
  is no longer valid.

* MUSDK 18.09 increased number of available bpools (buffer hw pools) by
  introducing dma regions support. Update mvpp2 driver accordingly.

* replace MV_NET_IP4_F_TOS with MV_NET_IP4_F_DSCP

  Before this patch, API allowed to configure a classification rule
  according to IPv4 TOS, which was not supported in classifier. This patch
  fixes this by using proper field.

* use 48 bit address mask

  We cannot get pointers exceeding 48 bits thus using 48 bit
  mask for extracting higher IOVA address bits is enough.

There is a strict dependency to MUSDK 18.09, dpdk18.11 won't compile with older
versions. It is hard to trace this dependency, what do you think having a matrix
in DPDK documentation showing which DPDK version supports which MUSDK?

It does not compile even with MUSDK 18.09.

With MUSDK 18.09, the error is:
	drivers/crypto/mvsam/rte_mrvl_pmd.c:867:26: error: 'SAM_HW_RING_NUM' undeclared

The explanation is in MUSDK:
commit 9bf8b3ca4ddfa00619c0023dfb08ae1601054fce
Author: Dmitri Epshtein <dima@marvell.com>
Date:   Mon Nov 20 10:38:31 2017 +0200

    sam: remove SAM_HW_RING_NUM from APIs
    
    Use function:
    u32 sam_get_num_cios(u32 inst);

As a consequence, next-net cannot be pulled!

I confirm same error. I wasn't building with crypto PMD enabled so not caught it.

We're checking the error and will provide fix asap. Please let know if
this should be another version of the entire patchset or fix on top.

There is another comment from Thomas (mvpp2_tm.png).

Both "fix on top" and "new version" is OK for me, pick whichever easy for you.
For "fix on top", I will squash fixes to original commits, so fixes should be
separate patches with a information which commit it targets.

But overall build should not be broken, it should be clear in which commit
dependency changed to 18.09. Let call the commit that switch happens X,
all commits before X should compile successfully with 17.10, commit X and all
following commits should be compile successfully with 18.09.

I will provide the new patchset shortly with following patch:
http://patches.dpdk.org/patch/44255/
already "squashed"/applied.  This is the patch for updating mvsam to
MUSDK 18.09 which solves the problem you experience but I guess it goes
to next-crypto.  That way I hope there would be no problem with merging
next-crypto and next-net will be able to compile.

Best regards
Andrzej

+Traffic Management API
+----------------------
+
+MVPP2 PMD supports generic DPDK Traffic Management API which allows to
+configure the following features:
+
+1. Hierarchical scheduling
+2. Traffic shaping
+3. Congestion management
+4. Packet marking
+
+Internally TM is represented by a hierarchy (tree) of nodes.
+Node which has a parent is called a leaf whereas node without
+parent is called a non-leaf (root).
+MVPP2 PMD supports two level hierarchy where level 0 represents ports and level 1 represents tx queues of a given port.
+
+.. figure:: img/mvpp2_tm.png
+
+Nodes hold following types of settings:
+
+- for egress scheduler configuration: weight
+- for egress rate limiter: private shaper
+- bitmask indicating which statistics counters will be read
+
+Hierarchy is always constructed from the top, i.e first a root node is added
+then some number of leaf nodes. Number of leaf nodes cannot exceed number
+of configured tx queues.
+
+After hierarchy is complete it can be committed.
+
+
+For an additional description please refer to DPDK :doc:`Traffic Management API <../prog_guide/traffic_management>`.
+
+Limitations
+~~~~~~~~~~~
+
+The following capabilities are not supported:
+
+- Traffic manager WRED profile and WRED context
+- Traffic manager shared shaper update
+- Traffic manager packet marking
+- Maximum number of levels in hierarchy is 2
+- Currently dynamic change of a hierarchy is not supported
+
+Usage example
+~~~~~~~~~~~~~
+

[dpdk-dev] [PATCH v2 12/12] net/mvpp2: add Tx S/G support

[Tomasz Duszynski]

From: Zyta Szpak <zr@semihalf.com>

The patch introduces scatter/gather support on transmit path.
A separate Tx callback is added and set if the application
requests multisegment Tx offload. Multiple descriptors are
sent per one packet.

[dpdk-dev] [PATCH v3 00/13] net/mvpp2: add new features

[Andrzej Ostruszka]

This patch series introduces fixes and adds support for traffic metering,
traffic manager and Tx S/G. Additionally it aligns with for MUSDK 18.09.

Changes in v3:
* change the format of image referred in doc (png -> svg)
* "cherry-pick" http://patches.dpdk.org/patch/44255/ to be part of this
  patch set so that next-net can compile with new MUSDK also when mvsam
  is enabled

Changes since v2:
* Align with MUSDK 18.09 library
* Add support for Tx Gather.
* Add documentation related to MTR and TM.
* Align documentation with MUSDK 18.09

[dpdk-dev] [PATCH v3 01/13] net/mvpp2: initialize ppio only once

[Andrzej Ostruszka]

From: Natalie Samsonov <nsamsono@marvell.com>

This changes stop/start/configure behavior due to issue in MUSDK
library itself.  From now on, ppio can be reconfigured only after interface
is closed.

[dpdk-dev] [PATCH v3 04/13] net/mvpp2: change default policer configuration

[Andrzej Ostruszka]

From: Tomasz Duszynski <tdu@semihalf.com>

Change QoS configuration file syntax for port's default policer
setup.

Since default policer configuration is performed before
any other policer configuration we can pick a default id.

This simplifies default policer configuration since user
no longer has to choose ids from range [0, PP2_CLS_PLCR_NUM].

Explicitly document values for rate_limit_enable field.

[dpdk-dev] [PATCH v3 05/13] net/mvpp2: add init and deinit to flow

[Andrzej Ostruszka]

From: Tomasz Duszynski <tdu@semihalf.com>

Add init and deinit functionality to flow implementation.

Init puts structures used by flow in a sane sate.
Deinit deallocates all resources used by flow.

[dpdk-dev] [PATCH v3 07/13] net/mvpp2: detach Tx QoS from Rx cls/QoS config

[Andrzej Ostruszka]

From: Yuval Caduri <cyuval@marvell.com>

Functional change:
Open receive cls/qos related features, only if the
config file contains an rx_related configuration entry.
This allows to configure tx_related entries, w/o unintentionally
opening rx cls/qos.

Code:
'use_global_defaults' is by default set to '1'.
Only if an rx_related entry was configured, it is updated to '0'.
rx cls/qos is performed only if 'use_global_defaults' is '0'.
Default TC configuration is now only mandatory when
'use_global_defaults' is '0'.

[dpdk-dev] [PATCH v3 09/13] net/mvpp2: align with MUSDK 18.09

[Andrzej Ostruszka]

From: Tomasz Duszynski <tdu@semihalf.com>

This patch introduces necessary changes required by MUSDK 18.09 library.

* As of MUSDK 18.09, pp2_cookie_t is no longer available. Now
  RX descriptor cookie is defined as plain u64 so existing cast
  is no longer valid.

* MUSDK 18.09 increased number of available bpools (buffer hw pools) by
  introducing dma regions support. Update mvpp2 driver accordingly.

* replace MV_NET_IP4_F_TOS with MV_NET_IP4_F_DSCP

  Before this patch, API allowed to configure a classification rule
  according to IPv4 TOS, which was not supported in classifier. This patch
  fixes this by using proper field.

* use 48 bit address mask

  We cannot get pointers exceeding 48 bits thus using 48 bit
  mask for extracting higher IOVA address bits is enough.

+Traffic Management API
+----------------------
+
+MVPP2 PMD supports generic DPDK Traffic Management API which allows to
+configure the following features:
+
+1. Hierarchical scheduling
+2. Traffic shaping
+3. Congestion management
+4. Packet marking
+
+Internally TM is represented by a hierarchy (tree) of nodes.
+Node which has a parent is called a leaf whereas node without
+parent is called a non-leaf (root).
+MVPP2 PMD supports two level hierarchy where level 0 represents ports and level 1 represents tx queues of a given port.
+
+.. figure:: img/mvpp2_tm.svg
+
+Nodes hold following types of settings:
+
+- for egress scheduler configuration: weight
+- for egress rate limiter: private shaper
+- bitmask indicating which statistics counters will be read
+
+Hierarchy is always constructed from the top, i.e first a root node is added
+then some number of leaf nodes. Number of leaf nodes cannot exceed number
+of configured tx queues.
+
+After hierarchy is complete it can be committed.
+
+
+For an additional description please refer to DPDK :doc:`Traffic Management API <../prog_guide/traffic_management>`.
+
+Limitations
+~~~~~~~~~~~
+
+The following capabilities are not supported:
+
+- Traffic manager WRED profile and WRED context
+- Traffic manager shared shaper update
+- Traffic manager packet marking
+- Maximum number of levels in hierarchy is 2
+- Currently dynamic change of a hierarchy is not supported

[dpdk-dev] [PATCH v3 13/13] net/mvpp2: add Tx scatter/gather support

[Andrzej Ostruszka]

From: Zyta Szpak <zr@semihalf.com>

The patch introduces scatter/gather support on transmit path.
A separate Tx callback is added and set if the application
requests multisegment Tx offload. Multiple descriptors are
sent per one packet.
