Subject: [PATCH v3 7/7] app/testpmd: add LWM and Host Shaper command
Date: Tue, 24 May 2022 18:20:41 +0300 [thread overview]
Message-ID: <20220524152041.737154-8-spiked@nvidia.com> (raw)
In-Reply-To: <20220524152041.737154-1-spiked@nvidia.com>
Add command line options to support LWM per-rxq configure.
- Command syntax:
set port <port_id> rxq <rxq_id> lwm <lwm_num>
mlx5 set port <port_id> host_shaper lwm_triggered <0|1> rate <rate_num>
- Example commands:
To configure LWM as 30% of rxq size on port 1 rxq 0:
testpmd> set port 1 rxq 0 lwm 30
To disable LWM on port 1 rxq 0:
testpmd> set port 1 rxq 0 lwm 0
To enable lwm_triggered on port 1 and disable current host shaper:
testpmd> mlx5 set port 1 host_shaper lwm_triggered 1 rate 0
To disable lwm_triggered and current host shaper on port 1:
testpmd> mlx5 set port 1 host_shaper lwm_triggered 0 rate 0
The rate unit is 100Mbps.
To disable lwm_triggered and configure a shaper of 5Gbps on port 1:
testpmd> mlx5 set port 1 host_shaper lwm_triggered 0 rate 50
Add sample code to handle rxq LWM event, it delays a while so that rxq
empties, then disables host shaper and rearms LWM event.

throttling host traffic on LWM events at minimum latency, preventing excess
drops in the Rx queue.
+How to use LWM and Host Shaper
+------------------------------
+
+There are sample command lines to configure LWM in testpmd.
+Testpmd also contains sample logic to handle LWM event.
+The typical workflow is: testpmd configure LWM for Rx queues, enable
+lwm_triggered in host shaper and register a callback, when traffic from host is
+too high and Rx queue fullness is above LWM, PMD receives an event and
+firmware configures a 100Mbps shaper on host port automatically, then PMD call
+the callback registered previously, which will delay a while to let Rx queue
+empty, then disable host shaper.
+
+Let's assume we have a simple Blue Field 2 setup: port 0 is uplink, port 1
+is VF representor. Each port has 2 Rx queues.
+In order to control traffic from host to ARM, we can enable LWM in testpmd by:
+
+.. code-block:: console
+
+ testpmd> mlx5 set port 1 host_shaper lwm_triggered 1 rate 0
+ testpmd> set port 1 rxq 0 lwm 70
+ testpmd> set port 1 rxq 1 lwm 70
+
+The first command disables current host shaper, and enables LWM triggered mode.
+The left commands configure LWM to 70% of Rx queue size for both Rx queues,
+When traffic from host is too high, you can see testpmd console prints log
+about LWM event receiving, then host shaper is disabled.
+The traffic rate from host is controlled and less drop happens in Rx queues.
+
+When disable LWM and lwm_triggered, we can invoke below commands in testpmd:
+
+.. code-block:: console
+
+ testpmd> mlx5 set port 1 host_shaper lwm_triggered 0 rate 0
+ testpmd> set port 1 rxq 0 lwm 0
+ testpmd> set port 1 rxq 1 lwm 0
+
+It's recommended an application disables LWM and lwm_triggered before exit,
+if it enables them before.
+
+We can also configure the shaper with a value, the rate unit is 100Mbps, below
+command sets current shaper to 5Gbps and disables lwm_triggered.
+
+.. code-block:: console
+
+ testpmd> mlx5 set port 1 host_shaper lwm_triggered 0 rate 50
