From: Tomasz Duszynski @ 2018-09-04 7:10 UTC (permalink / raw)
To: dev; +Cc: nsamsono, mw, 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.

To: dev; +Cc: nsamsono, mw, Yuval Caduri
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'.

From: Tomasz Duszynski @ 2018-09-04 13:49 UTC (permalink / raw)
To: dev; +Cc: nsamsono, mw, 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.

From: Tomasz Duszynski @ 2018-09-04 13:49 UTC (permalink / raw)
To: dev; +Cc: nsamsono, mw, Yuval Caduri
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'.

To: dev; +Cc: nsamsono, mw, Tomasz Duszynski, Yuval Caduri
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is no longer valid.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.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

To: dev; +Cc: nsamsono, mw, Zyta Szpak
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.

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

sam: remove SAM_HW_RING_NUM from APIs
Use function:

As a consequence, next-net cannot be pulled!

Sorry, it is forbidden to add new binary file.
As an Open Source project, everything must be open including the source
of the figures. Please could you provide a SVG version?

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.
Sorry for the problems.

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.

Yes I think it's better to re-consider this patchset later.

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

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

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.

From: Andrzej Ostruszka @ 2018-09-25 7:05 UTC (permalink / raw)
To: dev; +Cc: mw, nadavh, Tomasz Duszynski, Natalie Samsonov
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.

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.

From: Andrzej Ostruszka @ 2018-09-25 7:05 UTC (permalink / raw)
To: dev; +Cc: mw, nadavh, Yuval Caduri
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'.

From: Andrzej Ostruszka @ 2018-09-25 7:05 UTC (permalink / raw)
To: dev; +Cc: mw, nadavh, Tomasz Duszynski, Natalie Samsonov, Yuval Caduri
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

From: Andrzej Ostruszka @ 2018-09-25 7:05 UTC (permalink / raw)
To: dev; +Cc: mw, nadavh, Zyta Szpak, Natalie Samsonov
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.
