[dpdk-dev] [PATCH 1/3] app/testpmd: support Tx mbuf free on demand cmd

[Lijun Ou]

From: Chengwen Feng <fengchengwen@huawei.com>

This patch support tx_done_cleanup command:
tx_done_cleanup port (port_id) (queue_id) (free_cnt)

User must make sure there are no concurrent access to the same Tx
queue (like rte_eth_tx_burst, rte_eth_dev_tx_queue_stop and so on)
when this command executed.

[dpdk-dev] [PATCH 2/3] app/testpmd: remove forwarding config from parsing Rx and Tx

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

The "fwd_config_setup()" function does release and apply for
memory of forwarding flows, and re-establish these flows when
rxq/txq or rxd/txd is changed. The function is also called by
"start_packet_forwarding()" when user executes "start" cmd.
All changes for rxq/txq or rxd/txd can be updated uniformly
when this command is executed. Therefore, it is a little
redundant in the "cmd_config_rx_tx_parsed" function.

In addition, the forwarding flows under one TC is configured
based on number of queues allocated to TC. And number of queues
allocated to TC is updated after calling  "rte_eth_dev_configure"
again. If the number of queues is reduced after configuring the
DCB, and then, release and apply for flow memory, and reinitialize
the forwarding flows under the DCB mode based on the old TC
information. As a result, null pointer may be accessed.

Like:
set nbcore 4
port stop all
port config 0 dcb vt off 4 pfc on
port start all
port stop all
port config all rxq 8
port config all txq 8

At the moment, a segmentation fault occurs.

The patch looks good to me. But in commit log, you mean forwarding streams, right? Flows will confuse to mean rte_flow.

[dpdk-dev] [PATCH 3/3] app/testpmd: fix mixed use of RX/Rx/TX/Tx in testpmd

[Lijun Ou]

From: Hongbo Zheng <zhenghongbo3@huawei.com>

In testpmd, when we input "show config rxtx", we can see like this:

1: testpmd> show config rxtx
2:   io packet forwarding packets/burst=32
3:   nb forwarding cores=1 - nb forwarding ports=1
4:   port 0: RX queue number: 1 Tx queue number: 1
5:     Rx offloads=0x0 Tx offloads=0x10000
6:     RX queue: 0
7:       RX desc=1024 - RX free threshold=32
8:       RX threshold registers: pthresh=0 hthresh=0  wthresh=0
9:       RX Offloads=0x0
10:    TX queue: 0
11:      TX desc=1024 - TX free threshold=928
12:      TX threshold registers: pthresh=0 hthresh=0  wthresh=0
13:      TX offloads=0x10000 - TX RS bit threshold=32

In line 4, RX/Tx is mixed used. Also in other lines, RX/Rx/TX/Tx is
mixed used.

This patch fix the mixed use of RX/Rx/TX/Tx in testpmd command
"show config rxtx" output by change to unified use Rx/Tx.

If you're going to unify the print to only use "Rx/Tx" in testpmd as your title said.
There're a lot of more places using RX/TX when printing. You should change them too.

Please separate this patchset to 3 patches.
For the first patch, you should add a release note in release_21_05.rst.
And for the next 2 fixes, please add corresponding fix line and cc to stable@dpdk.org. 

And also, if you're sending patches related to testpmd, please also send/cc to me.
You can use add "--to-cmd ./devtools/get-maintainer.sh" when you use git send-email to make sure all of related people will be in mail list.
