[dpdk-dev] [PATCH 04/13] net/hns3: add Rx and Tx bytes stats

[Lijun Ou]

From: "Min Hu (Connor)" <humin29@huawei.com>

In current HNS3 PMD, Rx/Tx bytes from packet stats are not
implemented.

This patch implemented Rx/Tx bytes using soft counters.
Rx/Tx bytes stats will be enabled if the macro
RTE_LIBRTE_HNS3_PMD_SOFT_COUNTERS is defined.

[dpdk-dev] [PATCH 06/13] net/hns3: encapsulate a port shaping interface

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

When rate of port changes, the rate limit of the port needs to
be updated. So it is necessary to encapsulate an interface that
configures the rate limit based on the rate.

[dpdk-dev] [PATCH 07/13] net/hns3: support PF on electrical net device

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

The normal operation of electrical interface devices depends on the
initialization and configuration of the PHY chip. The task of driving
the PHY chip is implemented in some firmware versions. If firmware
supports the phy driver, it will report a capability flag to driver
in probing process. The driver determines whether to support electrical
device based on the capability bit. If supported, the driver set a flag
indicating that the firmware takes over the PHY, and then the firmware
intializes the PHY.

This patch supports the query of link status and link info, and existing
basic features for electrical device.

[dpdk-dev] [PATCH 08/13] net/hns3: support RXD advanced layout

[Lijun Ou]

From: Chengwen Feng <fengchengwen@huawei.com>

Currently, the driver get packet type by parse the
L3_ID/L4_ID/OL3_ID/OL4_ID from Rx descriptor and then lookup multiple
tables, it's time consuming.

Now Kunpeng930 support advanced RXD layout, which:
1. Combine OL3_ID/OL4_ID to 8bit PTYPE filed, so the driver get packet
type by lookup only one table.
Note: L3_ID/L4_ID become reserved fileds.
2. The 1588 timestamp located at Rx descriptor instead of query from
firmware.
3. The L3E/L4E/OL3E/OL4E will be zero when L3L4P is zero, so driver
could optimize the good checksum calculations (when L3E/L4E is zero
then mark PKT_RX_IP_CKSUM_GOOD/PKT_RX_L4_CKSUM_GOOD).

Considering compatibility, the firmware will report capability of
RXD advanced layout, the driver will identify and enable it by default.

This patch only provides basic function: identify and enable the RXD
advanced layout, and lookup ptype table if supported.

[dpdk-dev] [PATCH 09/13] net/hns3: fix maximum frame size update after buffer alloc

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

After MTU changed, the buffer used to store packets in HW should be
reallocated. And buffer size is allocated based on the maximum frame
size in the PF struct. However, the value of maximum frame size  is
not updated in time when MTU is changed. This would lead to a packet
loss for not enough buffer.

This patch update the maximum frame size before reallocating the HW
buffer. And a rollback operation is added to avoid the side effects
of buffer reallocation failures.

Fixes: 1f5ca0b460cd ("net/hns3: support some device operations")
Fixes: d51867db65c1 ("net/hns3: add initialization")

[dpdk-dev] [PATCH 13/13] net/hns3: fix imprecise statistics

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, the hns3 statistics may be inaccurate due to the
following two problems:

1. Queue-level statistics are read from the firmware, and only
one Rx or Tx can be read at a time. This results in a large
time interval between reading multiple queues statistics in a
stress scenario, such as 1280 queues used by a PF or 256 functions
used at the same time. Especially when the 256 functions are used
at the same time, the interval between every two firmware commands
in a function can be huge, because the scheduling mechanism of the
firmware is similar to RR.

2. The current statistics are read by type. The HW statistics are
read first, and then the software statistics are read. Due to
preceding reasons, HW reading may be time-consuming, which cause
a synchronization problem between SW and HW statistics of the same
queue.

In this patch, queue-level statistics are directly read from the bar
instead of the firmware, and all the statistics of a queue include HW
and SW are read at a time to reduce inconsistency.

Fixes: 8839c5e202f3 ("net/hns3: support device stats")

Why statistics enabled only with macro?
It is not common to use macro to enable the stats, what do you think to remove 
it, to be consistent with rest of the PMDs?

Isn't the patch title should say 'before', like:
net/hns3: fix maximum frame size update _before_ buffer alloc

Or perhaps I get the patch wrong...

Is the "electrical net device" means electrical PHY, would it be OK to update it 
as this?

What is MAC TNL Interrupt, can you please provide more information in the commit 
log?
And what is done as interrupt handling, as far as I can see it is doing more 
that just logging it.

The expression here may vary from different perspectives. From a 
hardware standpoint, the problem is that the maximum frame size update 
buffer allocation. From a software standpoint, the the buffer size that 
should be allocted depends on the maximum frame size kept in the driver, 
and the problem is caused by the late value update in the driver.

TNL is the abbreviation of tunnel, which means port here.
Mac TNL interrupt indicates the MAC status report of the network port, 
which will be generated when the MAC status changes.

This patch enables MAC TNL interrupt reporting, and queries
and prints the corresponding MAC status when the interrupt
is received, then clear the mac interrupt status. Because this
interrupt uses the same interrupt as Ras, the interrupt log is
adjusted.

There is no electrical PHY. Only electrical PHY is supported in kernel 
mode. What do you think?
copper phy?

I am just trying to understand what is "electrical net device" is, or 
"electrical interface" mentioned in the commit log, I guess you mean non-optical 
interface, if the "copper PHY" is better terminology for it, please use it.

[dpdk-dev] [PATCH V2 04/14] net/hns3: add Rx and Tx bytes stats

[Lijun Ou]

From: "Min Hu (Connor)" <humin29@huawei.com>

In current HNS3 PMD, Rx/Tx bytes from packet stats are not
implemented.

This patch implemented Rx/Tx bytes using soft counters.
Rx/Tx bytes stats will be enabled if the macro
RTE_LIBRTE_HNS3_PMD_SOFT_COUNTERS is defined.

[dpdk-dev] [PATCH V2 06/14] net/hns3: encapsulate a port shaping interface

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

When rate of port changes, the rate limit of the port needs to
be updated. So it is necessary to encapsulate an interface that
configures the rate limit based on the rate.

[dpdk-dev] [PATCH V2 07/14] net/hns3: fix device capabilities for copper media type

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

The configuration operation for PHY is implemented by firmware. And
a capability flag will be report to driver, which means the firmware
supports the PHY driver.  However, the current implementation only
supports obtaining the capability bit, but some basic functions of
copper ports in driver, such as, the query of link status and link
info, are not supported.

Therefore, it is necessary for driver to set the copper capability
bit to zero when the firmware supports the configuration of the PHY.

Fixes: 438752358158 ("net/hns3: get device capability from firmware")
Fixes: 95e50325864c ("net/hns3: support copper media type")

[dpdk-dev] [PATCH V2 08/14] net/hns3: support PF device with copper phys

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

The normal operation of devices with copper phys depends on the
initialization and configuration of the PHY chip. The task of
driving the PHY chip is implemented in some firmware versions.
If firmware supports the phy driver, it will report a capability
flag to driver in probing process. The driver determines whether
to support PF device with copper phys based on the capability bit.
If supported, the driver set a flag indicating that the firmware
takes over the PHY, and then the firmware initializes the PHY.

This patch supports the query of link status and link info, and
existing basic features for PF device with copper phys.

[dpdk-dev] [PATCH V2 09/14] net/hns3: support RXD advanced layout

[Lijun Ou]

From: Chengwen Feng <fengchengwen@huawei.com>

Currently, the driver get packet type by parse the
L3_ID/L4_ID/OL3_ID/OL4_ID from Rx descriptor and then lookup multiple
tables, it's time consuming.

Now Kunpeng930 support advanced RXD layout, which:
1. Combine OL3_ID/OL4_ID to 8bit PTYPE filed, so the driver get packet
type by lookup only one table.
Note: L3_ID/L4_ID become reserved fields.
2. The 1588 timestamp located at Rx descriptor instead of query from
firmware.
3. The L3E/L4E/OL3E/OL4E will be zero when L3L4P is zero, so driver
could optimize the good checksum calculations (when L3E/L4E is zero
then mark PKT_RX_IP_CKSUM_GOOD/PKT_RX_L4_CKSUM_GOOD).

Considering compatibility, the firmware will report capability of
RXD advanced layout, the driver will identify and enable it by default.

This patch only provides basic function: identify and enable the RXD
advanced layout, and lookup ptype table if supported.

[dpdk-dev] [PATCH V2 10/14] net/hns3: fix maximum frame size update after buffer alloc

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

After MTU changed, the buffer used to store packets in HW should be
reallocated. And buffer size is allocated based on the maximum frame
size in the PF struct. However, the value of maximum frame size  is
not updated in time when MTU is changed. This would lead to a packet
loss for not enough buffer.

This patch update the maximum frame size before reallocating the HW
buffer. And a rollback operation is added to avoid the side effects
of buffer reallocation failures.

[dpdk-dev] [PATCH V2 11/14] net/hns3: remove unused parameter from func declaration

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

All input parameters in the "hns3_dev_xstats_get_by_id" API are used,
so the rte_unused flag of some variables should be deleted.

[dpdk-dev] [PATCH V2 13/14] net/hns3: add process for MAC interrupt

[Lijun Ou]

From: Hongbo Zheng <zhenghongbo3@huawei.com>

TNL is the abbreviation of tunnel, which means port
here. MAC TNL interrupt indicates the MAC status
report of the network port, which will be generated
when the MAC status changes.

This patch enables MAC TNL interrupt reporting, and
queries and prints the corresponding MAC status when
the interrupt is received, then clear the MAC interrupt
status. Because this interrupt uses the same interrupt
as RAS, the interrupt log is adjusted.

[dpdk-dev] [PATCH V2 14/14] net/hns3: fix imprecise statistics

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, the hns3 statistics may be inaccurate due to the
following two problems:

1. Queue-level statistics are read from the firmware, and only
one Rx or Tx can be read at a time. This results in a large
time interval between reading multiple queues statistics in a
stress scenario, such as 1280 queues used by a PF or 256 functions
used at the same time. Especially when the 256 functions are used
at the same time, the interval between every two firmware commands
in a function can be huge, because the scheduling mechanism of the
firmware is similar to RR.

2. The current statistics are read by type. The HW statistics are
read first, and then the software statistics are read. Due to
preceding reasons, HW reading may be time-consuming, which cause
a synchronization problem between SW and HW statistics of the same
queue.

In this patch, queue-level statistics are directly read from the bar
instead of the firmware, and all the statistics of a queue include HW
and SW are read at a time to reduce inconsistency.

The order in the release notes is documented in the section comment, and within 
the PMDs we are trying to keep in the vendor alphabetical order, can you please 
order accordingly.

With current release notes, "Hisilicon hns3" updates should go as first item in 
the section.

Hi Lijun,

I see this patch is to be accurate, but in next patch the link status is 
implemented and this patch practically reverted back completely, so I guess this 
patch can be dropped, what do you think?

copy/paste from previous version:

Why statistics enabled only with macro?
It is not common to use macro to enable the stats, what do you think to remove 
it, to be consistent with rest of the PMDs?

Yes, I am.  I split up on purpose. We find that if patch [8/14] is not 
integrated, the COPPER function should not be supported in 
hw->capability.That is, in 20.11 and 21.02, hw->capability should not 
support copper,this patch needs to be backported to 20.11 and 21.02.
For the above reasons, we'll split it up.

make sense from backporting point of view, OK to continue as it is.

I'm sorry. I thought it was a success.
  Firstly, the macro is used to control the statistics to ensure 
performance and facilitate flexible usage. For example, the macro needs 
to be disabled when high performance is required.
secondly the byte statistics of other vendors are implemented by reading 
and writing registers. Therefore, macros are not used.By the way, the 
MLX driver has a precedent (code snippets can be intercepted here).

It is not convenient for a user re-compile the DPDK to be able to get the ethdev 
byte statistics, stats are not developer/debug information, end user may need 
them. And this recompilation may not be an option for the distributed software.

How much performance affect it has if you enable it always?

And just to double check, isn't there a way to get this information from HW 
without calculating it in the driver?

The compile time flags, specially after meson switch, hard to enable and a 
little hidden, it is very easy to have broken code there, that is why it better 
to prevent compile time flags as much as possible.

We theoretically analyzed that being on a critical path might have a 
performance impact. Maybe the actual mountain is negligible.

After internal analysis, you can accept your comments and remove macros.

[dpdk-dev] [PATCH V3 04/14] net/hns3: add Rx and Tx bytes stats

[Lijun Ou]

From: "Min Hu (Connor)" <humin29@huawei.com>

In current HNS3 PMD, Rx/Tx bytes from packet stats are not
implemented.

This patch implemented Rx/Tx bytes using soft counters.

[dpdk-dev] [PATCH V3 06/14] net/hns3: encapsulate a port shaping interface

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

When rate of port changes, the rate limit of the port needs to
be updated. So it is necessary to encapsulate an interface that
configures the rate limit based on the rate.

[dpdk-dev] [PATCH V3 07/14] net/hns3: fix device capabilities for copper media type

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

The configuration operation for PHY is implemented by firmware. And
a capability flag will be report to driver, which means the firmware
supports the PHY driver.  However, the current implementation only
supports obtaining the capability bit, but some basic functions of
copper ports in driver, such as, the query of link status and link
info, are not supported.

Therefore, it is necessary for driver to set the copper capability
bit to zero when the firmware supports the configuration of the PHY.

Fixes: 438752358158 ("net/hns3: get device capability from firmware")
Fixes: 95e50325864c ("net/hns3: support copper media type")

[dpdk-dev] [PATCH V3 08/14] net/hns3: support PF device with copper phys

[Lijun Ou]

From: Huisong Li <lihuisong@huawei.com>

The normal operation of devices with copper phys depends on the
initialization and configuration of the PHY chip. The task of
driving the PHY chip is implemented in some firmware versions.
If firmware supports the phy driver, it will report a capability
flag to driver in probing process. The driver determines whether
to support PF device with copper phys based on the capability bit.
If supported, the driver set a flag indicating that the firmware
takes over the PHY, and then the firmware initializes the PHY.

This patch supports the query of link status and link info, and
existing basic features for PF device with copper phys.

[dpdk-dev] [PATCH V3 09/14] net/hns3: support RXD advanced layout

[Lijun Ou]

From: Chengwen Feng <fengchengwen@huawei.com>

Currently, the driver get packet type by parse the
L3_ID/L4_ID/OL3_ID/OL4_ID from Rx descriptor and then lookup multiple
tables, it's time consuming.

Now Kunpeng930 support advanced RXD layout, which:
1. Combine OL3_ID/OL4_ID to 8bit PTYPE filed, so the driver get packet
type by lookup only one table.
Note: L3_ID/L4_ID become reserved fields.
2. The 1588 timestamp located at Rx descriptor instead of query from
firmware.
3. The L3E/L4E/OL3E/OL4E will be zero when L3L4P is zero, so driver
could optimize the good checksum calculations (when L3E/L4E is zero
then mark PKT_RX_IP_CKSUM_GOOD/PKT_RX_L4_CKSUM_GOOD).

Considering compatibility, the firmware will report capability of
RXD advanced layout, the driver will identify and enable it by default.

This patch only provides basic function: identify and enable the RXD
advanced layout, and lookup ptype table if supported.

[dpdk-dev] [PATCH V3 10/14] net/hns3: fix HW buffer size on MTU update

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

After MTU changed, the buffer used to store packets in HW should be
reallocated. And buffer size is allocated based on the maximum frame
size in the PF struct. However, the value of maximum frame size  is
not updated in time when MTU is changed. This would lead to a packet
loss for not enough buffer.

This patch update the maximum frame size before reallocating the HW
buffer. And a rollback operation is added to avoid the side effects
of buffer reallocation failures.

Fixes: 1f5ca0b460cd ("net/hns3: support some device operations")
Fixes: d51867db65c1 ("net/hns3: add initialization")

All input parameters in the "hns3_dev_xstats_get_by_id" API are used,
so the rte_unused flag of some variables should be deleted.

[dpdk-dev] [PATCH V3 13/14] net/hns3: add process for MAC interrupt

[Lijun Ou]

From: Hongbo Zheng <zhenghongbo3@huawei.com>

TNL is the abbreviation of tunnel, which means port
here. MAC TNL interrupt indicates the MAC status
report of the network port, which will be generated
when the MAC status changes.

This patch enables MAC TNL interrupt reporting, and
queries and prints the corresponding MAC status when
the interrupt is received, then clear the MAC interrupt
status. Because this interrupt uses the same interrupt
as RAS, the interrupt log is adjusted.

[dpdk-dev] [PATCH V3 14/14] net/hns3: fix imprecise statistics

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, the hns3 statistics may be inaccurate due to the
following two problems:

1. Queue-level statistics are read from the firmware, and only
one Rx or Tx can be read at a time. This results in a large
time interval between reading multiple queues statistics in a
stress scenario, such as 1280 queues used by a PF or 256 functions
used at the same time. Especially when the 256 functions are used
at the same time, the interval between every two firmware commands
in a function can be huge, because the scheduling mechanism of the
firmware is similar to RR.

2. The current statistics are read by type. The HW statistics are
read first, and then the software statistics are read. Due to
preceding reasons, HW reading may be time-consuming, which cause
a synchronization problem between SW and HW statistics of the same
queue.

In this patch, queue-level statistics are directly read from the bar
instead of the firmware, and all the statistics of a queue include HW
and SW are read at a time to reduce inconsistency.

Fixes: 8839c5e202f3 ("net/hns3: support device stats")
