This patch set contains one patch for performance optimization,
this is: 'net/hns3: improve IO path data cache usage'.
The others are bugfixes for hns3 PMD.
Chengwen Feng (6):
net/hns3: delete some unused capabilities
net/hns3: modify write reg opt API impl
net/hns3: use RTE DIM instead of ARRAY SIZE
net/hns3: improve IO path data cache usage
net/hns3: log fdir configuration
net/hns3: fix vector Rx burst default value

To: dev; +Cc: ferruh.yigit
From: Chengwen Feng <fengchengwen@huawei.com>
This patch improves data cache usage by:
1. Rearrange the rxq frequency accessed fields in the IO path to the
first 128B.
2. Rearrange the txq frequency accessed fields in the IO path to the
first 64B.
3. Make sure ptype table align cacheline size which is 128B instead of
min cacheline size which is 64B because the L1/L2 is 64B and L3 is
128B on Kunpeng ARM platform.
The performance gains are 1.5% in 64B packet macfwd scenarios.

Currently, driver uses the macro HNS3_DEFAULT_RX_BURST whose value is
32 to limit the vector Rx burst size, as a result, the burst size user
configure can't exceed 32.
This patch fixes this problem by defining the macro
HNS3_DEFAULT_RX_BURST as 64.

This cause some values to be changed, because of added/removed items, is this
expected?
If so can you please mention from this value change in the commit log, to clarify.

If the messages are for debugging, what do you think about add them as
'hns3_dbg'? Isn't info level too verbose for debugging?

It seems in the vector Rx path, the number of receive packets are limited
silently to 'HNS3_DEFAULT_RX_BURST' independent from what user requested/configured.
There can be driver/HW limitations to 'HNS3_DEFAULT_RX_BURST' that is OK, but
instead of limiting user request, what do you think about Rx in the
'HNS3_DEFAULT_RX_BURST' blocks until user request justified?
I mean something like following implementation:

If the messages are for debugging, what do you think about add them as
'hns3_dbg'? Isn't info level too verbose for debugging?
yes, it was used for debugging and log analyzing, we use hns3_info because the default level may not debug in product scenario.
we use verbose readable log because it's useful for reading.
thanks

It is possible to dynamically change the log level and get debug logs when

This cause some values to be changed, because of added/removed items, is this
expected?
If so can you please mention from this value change in the commit log, to clarify.
these values are used only in driver, so the order could adjust.
the commit log memtion it brifely, which is:
2. Delete some unused driver capabilities definition

I am not talking about deletion of unused macros,
Please mention that value of some of the macros have been changed and this is
known and won't cause a problem.

It seems in the vector Rx path, the number of receive packets are limited
silently to 'HNS3_DEFAULT_RX_BURST' independent from what user requested/configured.
There can be driver/HW limitations to 'HNS3_DEFAULT_RX_BURST' that is OK, but
instead of limiting user request, what do you think about Rx in the
'HNS3_DEFAULT_RX_BURST' blocks until user request justified?
I mean something like following implementation:

sound good, will fix in v2, thanks

This patch set contains one patch for performance optimization,
this is: 'net/hns3: improve IO path data cache usage'.
The others are bugfixes for hns3 PMD.
Chengwen Feng (6):
net/hns3: delete some unused capabilities
net/hns3: modify write reg opt API impl
net/hns3: use RTE DIM instead of ARRAY SIZE
net/hns3: improve IO path data cache usage
net/hns3: log fdir configuration
net/hns3: fix vector Rx burst can't exceed 32
---
v2:
* fixed commit info.
* changed hns3_info to hns3_dbg.
* deleted tx push, simple bd capa.

This patch deletes some unused capabilities, include:
1. Delete some unused firmware capabilities definition, which are:
UDP_GSO, ATR, INT_QL, SIMPLE_BD, TX_PUSH, FEC and PAUSE.
2. Delete some unused driver capabilities definition, which are:
UDP_GSO, TX_PUSH.
3. Also redefine HNS3_DEV_SUPPORT_* as enum type, and change some of
the values. Note: the HNS3_DEV_SUPPORT_* values is used only inside
the driver, so it's safe to change the values.

This patch modifies hns3_write_reg_opt() API implementation because
the rte_write32() already uses rte_io_wmb().

From: Chengwen Feng <fengchengwen@huawei.com>
This patch improves data cache usage by:
1. Rearrange the rxq frequency accessed fields in the IO path to the
first 128B.
2. Rearrange the txq frequency accessed fields in the IO path to the
first 64B.
3. Make sure ptype table align cacheline size which is 128B instead of
min cacheline size which is 64B because the L1/L2 is 64B and L3 is
128B on Kunpeng ARM platform.
The performance gains are 1.5% in 64B packet macfwd scenarios.

The rte flow interface does not support the API of the capability
set. Therefore, fdir configuration logs are added to facilitate
debugging.

From: Chengwen Feng <fengchengwen@huawei.com>
Currently, driver uses the macro HNS3_DEFAULT_RX_BURST whose value is
32 to limit the vector Rx burst size, as a result, the burst size
can't exceed 32.
This patch fixes this problem by support big burst size.
Also adjust HNS3_DEFAULT_RX_BURST to 64 as it performs better than 32.
Fixes: a3d4f4d291d7 ("net/hns3: support NEON Rx")
Fixes: 952ebacce4f2 ("net/hns3: support SVE Rx")

This patch set contains one patch for performance optimization,
this is: 'net/hns3: improve IO path data cache usage'.
The others are bugfixes for hns3 PMD.
Chengwen Feng (6):
net/hns3: delete some unused capabilities
net/hns3: modify write reg opt API impl
net/hns3: use RTE DIM instead of ARRAY SIZE
net/hns3: improve IO path data cache usage
net/hns3: log FDIR configuration
net/hns3: fix vector Rx burst can't exceed 32
---
v3:
* put the packet judgment error into the subfunction.
v2:
* fixed commit info.
* changed hns3_info to hns3_dbg.
* deleted tx push, simple bd capa.

This patch deletes some unused capabilities, include:
1. Delete some unused firmware capabilities definition, which are:
UDP_GSO, ATR, INT_QL, SIMPLE_BD, TX_PUSH, FEC and PAUSE.
2. Delete some unused driver capabilities definition, which are:
UDP_GSO, TX_PUSH.
3. Also redefine HNS3_DEV_SUPPORT_* as enum type, and change some of
the values. Note: the HNS3_DEV_SUPPORT_* values is used only inside
the driver, so it's safe to change the values.

From: Chengwen Feng <fengchengwen@huawei.com>
This patch improves data cache usage by:
1. Rearrange the rxq frequency accessed fields in the IO path to the
first 128B.
2. Rearrange the txq frequency accessed fields in the IO path to the
first 64B.
3. Make sure ptype table align cacheline size which is 128B instead of
min cacheline size which is 64B because the L1/L2 is 64B and L3 is
128B on Kunpeng ARM platform.
The performance gains are 1.5% in 64B packet macfwd scenarios.

set. Therefore, fdir configuration logs are added to facilitate

Currently, driver uses the macro HNS3_DEFAULT_RX_BURST whose value is
32 to limit the vector Rx burst size, as a result, the burst size
can't exceed 32.
This patch fixes this problem by support big burst size.
Also adjust HNS3_DEFAULT_RX_BURST to 64 as it performs better than 32.
