[dpdk-dev] [PATCH v2 00/13] support of multiple sizes of redirection table

[dpdk-dev] [PATCH v2 00/13] support of multiple sizes of redirection table

[Helin Zhang]

As e1000, ixgbe and i40e hardware use different sizes of redirection
table in PF or VF, ethdev and PMDs need to be reworked to support
multiple sizes of that table. In addition, commands in testpmd also
need to be reworked to support these changes.

v2 changes:
* Reorganize the patches.
* Add code style fixes.
* Add support of reta updating/querying in i40e VF.

Since commit http://dpdk.org/browse/dpdk/commit/?id=a30268e9a2
(ethdev: reset whole dev info structure before filling),
this patch is now useless.

[dpdk-dev] [PATCH v2 04/13] ethdev: support of multiple sizes of redirection table

[Helin Zhang]

To support possible different sizes of redirection table,
structures and functions need to be redefined. In detail,
* 'struct rte_eth_rss_reta' has been redefined.
* 'uint16_t reta_size' has been added into
  'struct rte_eth_dev_info'.
* Updating/querying reta have been reimplemented with one
  more parameter of redirection table size.

v2 changes:
* Put changes for supporting multiple sizes of reta in
  ethdev into a single patch.

In order to allow usage of git bisect, compilation must not be broken,
even inside a patchset.
So when refactoring an existing API, you must adapt the dependent code
in the same patch.
To make things easy to review, please try to change API incrementally
with good explanation of why each change is needed.

Are these constants really needed?

Explaining the array of 64 entries could be useful in commit log.
Please don't forget to answer the "why" question in commit logs.

OK. The patch set has been reworked to get all patches compiled well.

These constants were defined for the third input parameter of
rte_eth_dev_rss_reta_update() and rte_eth_dev_rss_reta_query(). End users need
to give the correct reta size listed as above, as other values is not valid. So it would be
better to list the valid reta sizes in macros here.

OK, so you should explain that only these values are allowed.
In general, it's something we explain in the comment of the function.

By the way, why only these values are allowed?

If only limited range of values are allowed, would an enum work better than a set of macros?

I would prefer the API to be independent of the hardware capabilities.

It depends on hardware, 1G/10G hardware supports 128 reta size only, 40G
hardware supports 512 or 128 depends on hardware configuration, 40G VF
hardware supports 64. If more is introduced in the future, more values can be
added later. It will return with errors if reta size is not supported for specific hardware.

So maybe it should be the responsibility of the driver to use
the right value. This kind of hardware differences should be abstracted
for the application.
If the application need to know the size, a "get" function could
be provided.

Yes, the size can be gotten by ops of 'dev_infos_get'. But if end users know the
size of a specific port, he can just use these macros directly without getting it
from somewhere.

Now do not think explain what value is allowed for the functions in ethdev layer,
as it might be hardware specific.
I think the best way is to comment out end users can get the reta size by
'dev_infos_get' on each port, rather than telling the values directly.

[dpdk-dev] [PATCH v2 13/13] app/testpmd: rework of commands for updating/querying reta

[Helin Zhang]

As multiple sizes of redirection table have been supported,
the commands of updating/querying reta need to be reworked
as well. In addition, the reta size can be queried by the
existing command of 'show port info <>'.

[dpdk-dev] [PATCH v3 0/8] support of multiple sizes of redirection table

[Helin Zhang]

As e1000, ixgbe and i40e hardware use different sizes of redirection
table in PF or VF, ethdev and PMDs need to be reworked to support
multiple sizes of that table. In addition, commands in testpmd also
need to be reworked to support these changes.

v2 changes:
* Reorganized the patches.
* Added code style fixes.
* Added support of reta updating/querying in i40e VF.

v3 changes:
* Reorganized the patch set.
* Added returning default RX/TX configurations in VF
  (igb/ixgbe/i40e), as the patch set of it for PF has been
  accepted recently.

Helin Zhang (8):
  app/testpmd: code style fix
  i40evf: code style fix
  i40e: support of setting hash lookup table size
  igb: implement ops of 'dev_infos_get' for PF and VF respectively
  ixgbe: implement ops of 'dev_infos_get' for PF and VF respectively
  i40e: rework of ops of 'dev_infos_get' for both PF and VF
  ethdev: support of multiple sizes of redirection table
  i40evf: support of updating/querying redirection table

You didn't answer to my previous comment on this.
I think these definitions are useless. 64 is 64.

Putting labels on the constants gives meaning to them as well as a numeric 
value. Not doing so is an antipattern referred to as "magic numbers" 
antipattern.

A maintainence programmer or community member will have a difficult time 
figuring out lost context when grepping through the code.

Are you kidding Matthew?
I'm referring to these constants:

It's not RETA_SIZE which would have a meaning but
RETA_SIZE_64. We could also define RETA_SIZE_32 or RETA_SIZE_33...

[dpdk-dev] [PATCH v3 4/8] igb: implement ops of 'dev_infos_get' for PF and VF respectively

[Helin Zhang]

As more and more information are different between PF and VF, ops of
'dev_infos_get' has been implemented respectively. In addition, new
field of 'reta_size' has been added in 'struct rte_eth_dev_info' for
returning redirection table size.

v2 changes:
* Added new function for ops of 'dev_infos_get' specifically for igb VF.

v3 changes:
* Put the adding new element of 'reta_size' in ethdev into this patch,
  as it is needed.
* Returning default RX/TX configurations has been added in ops of
  'dev_infos_get', as it was accepted recently in another patches.

[dpdk-dev] [PATCH v3 6/8] i40e: rework of ops of 'dev_infos_get' for both PF and VF

[Helin Zhang]

Returning redirection table size has been supported in ops of
'dev_infos_get' for both PF and VF. Default RX/TX configurations
of VF can be returned in ops of 'dev_infos_get', while it was
missed before.

v3 changes:
* Returning default RX/TX configurations has been added in ops of
  'dev_infos_get' for VF, as it was added recently in that for PF.

[dpdk-dev] [PATCH v3 7/8] ethdev: support of multiple sizes of redirection table

[Helin Zhang]

As 40G NIC supports different sizes (128/512/64 entries) of
redirection table from that (128 entries) of 1G and 10G NICs,
support of multiple sizes of redirection table is needed.
It includes,
* Redefine 'struct rte_eth_rss_reta' in ethdev.
  - To 'struct rte_eth_rss_reta_entry64' which contains 64
    entries and 64 bits mask.
  - Array of above new structure can be used for any number
    of redirection table entries, as long as the number is
    multiple of 64. This is quite flexible for the future
    expanding of redirection table.
* Redefinition of relevant interfaces in ethdev.
  - Interface of reta update has been redefined with new
    parameters.
  - Interface of reta query has been redefined with new
    parameters.
* Rework of 1G PMD in igb.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 10G PMD in ixgbe.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 40G PMD (PF only) in i40e.
  - reta update has been reworked.
  - reta query has been reworked.
* Implement relevant commands in testpmd.

How can it be different of 64?
Using 64 would be simpler to understand than RTE_BIT_WIDTH_64.

Even your comment is saying that it's 64.

We always try to use macro in code to replace numeric, this can get the numeric more understandable.

How bit width 64 is more understandable than 64?
Especially when you count a number of entries, not a bit width.
RETA_ENTRIES_MAX would be more understandable.

Renaming the macro is needed. I plan to rename it to RTE_RETA_GROUP_SIZE,
as it is a group of 64 reta entries, but not the maximum number of valid entries.

[dpdk-dev] [PATCH v4 0/8] support of multiple sizes of redirection table

[Helin Zhang]

As e1000, ixgbe and i40e hardware use different sizes of
redirection table in PF or VF, ethdev and PMDs need to be
reworked to support multiple sizes of that table. In
addition, commands in testpmd also need to be reworked to
support these changes.

v2 changes:
* Reorganized the patches.
* Added code style fixes.
* Added support of reta updating/querying in i40e VF.

v3 changes:
* Reorganized the patch set.
* Added returning default RX/TX configurations in VF
  (igb/ixgbe/i40e), as the patch set of it for PF has been
  accepted recently.

v4 changes:
* Renamed RTE_BIT_WIDTH_64 to RTE_RETA_GROUP_SIZE.
* Added more comments to rte_eth_dev_rss_reta_update() and
  rte_eth_dev_rss_reta_query().

[dpdk-dev] [PATCH v4 4/8] igb: implement ops of 'dev_infos_get' for PF and VF respectively

[Helin Zhang]

As more and more information are different between PF and VF,
ops of 'dev_infos_get' has been implemented respectively. In
addition, new field of 'reta_size' has been added in
'struct rte_eth_dev_info' for returning redirection table size.

* Added new function for ops of 'dev_infos_get' specifically for igb VF.

v3 changes:
* Put the adding new element of 'reta_size' in ethdev into this patch,
  as it is needed.
* Returning default RX/TX configurations has been added in ops of
  'dev_infos_get', as it was accepted recently in another patches.

[dpdk-dev] [PATCH v4 6/8] i40e: rework of ops of 'dev_infos_get' for both PF and VF

[Helin Zhang]

Returning redirection table size has been supported in
ops of 'dev_infos_get' for both PF and VF. Default
RX/TX configurations of VF can be returned in ops of
'dev_infos_get', while it was missed before.

[dpdk-dev] [PATCH v4 7/8] ethdev: support of multiple sizes of redirection table

[Helin Zhang]

As 40G NIC supports different sizes (128/512/64 entries)
of redirection table from that (128 entries) of 1G and
10G NICs, support of multiple sizes of redirection table
is needed. It includes,
* Redefine 'struct rte_eth_rss_reta' in ethdev.
  - To 'struct rte_eth_rss_reta_entry64' which contains 64
    entries and 64 bits mask.
  - Array of above new structure can be used for any number
    of redirection table entries, as long as the number is
    multiple of 64. This is quite flexible for the future
    expanding of redirection table.
* Redefinition of relevant interfaces in ethdev.
  - Interface of reta update has been redefined with new
    parameters.
  - Interface of reta query has been redefined with new
    parameters.
* Rework of 1G PMD in igb.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 10G PMD in ixgbe.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 40G PMD (PF only) in i40e.
  - reta update has been reworked.
  - reta query has been reworked.
* Implement relevant commands in testpmd.

Are these values still needed?
Why 256 is forbidden?

It was widely used in igb/ixgbe/i40e code, and app/testpmd. It is good to be kept there,
though we can define them separately in each component. This would be more convenient
for PMDs and user applications.

> Why 256 is forbidden?
256 is not a valid table size of current supported NICs, for other/future NIC which supports
this size, it can be added later as needed.

> Maybe that some comments are needed here.
Comments might not be needed, as their names tell us what they are clearly. Did you mean
any other annotations to be added for these macros? I am open for that to add any good
annotations for them.

If it should be used by applications, it must stay in ethdev.

The problem is that we don't know which value is supported for each driver.
You should add a comment like this:
/**@{
 * Some RSS RETA sizes may be not supported by some drivers.
 * Check in the PMD documentation.
 */
#define ETH_RSS_RETA_SIZE_64  64
#define ETH_RSS_RETA_SIZE_128 128
#define ETH_RSS_RETA_SIZE_512 512
/**@}*/

And then add some comments in the PMD to describe the supported sizes.

We just have to keep in mind that the API reference for users is in doxygen.
Some details are obvious for you but not clear for the user, especially if he
doesn't care about i40e.

Thanks

In rte_ethdev.h, there is comments for rte_eth_dev_rss_reta_update() and
rte_eth_dev_rss_reta_query() that the reta table size can be queried by
rte_eth_dev_info_get().
So the end users could know the reta size of each NIC by reading its datasheet,
or call that function to query the size directly.
The macros defined here let the reta size more straightforward, and easy to use.
OK, it is good to add some annotations here. Thanks!

[dpdk-dev] [PATCH v5 0/8] support of multiple sizes of redirection table

[Helin Zhang]

As e1000, ixgbe and i40e hardware use different sizes of redirection table in
PF or VF, ethdev and PMDs need to be reworked to support multiple sizes of that
table. In addition, commands in testpmd also need to be reworked to support
these changes.

v2 changes:
* Reorganized the patches.
* Added code style fixes.
* Added support of reta updating/querying in i40e VF.

v3 changes:
* Reorganized the patch set.
* Added returning default RX/TX configurations in VF (igb/ixgbe/i40e), as the
  patch set of it for PF has been accepted recently.

v4 changes:
* Renamed RTE_BIT_WIDTH_64 to RTE_RETA_GROUP_SIZE.
* Added more comments to rte_eth_dev_rss_reta_update() and
  rte_eth_dev_rss_reta_query().

v5 changes:
* Reworked the annotations of macros of RETA sizes in rte_ethdev.h.

[dpdk-dev] [PATCH v5 5/8] ixgbe: implement ops of 'dev_infos_get' for PF and VF respectively

[Helin Zhang]

As more and more information are different between PF and VF, ops of
'dev_infos_get' has been implemented respectively. In addition, returning
redirection table size has been supported in it.

v2 changes:
* Added new function for ops of 'dev_infos_get' specifically for ixgbe VF.

v3 changes:
* Returning default RX/TX configurations has been added in ops of
  'dev_infos_get' for VF, as it was added recently in that for PF.

[dpdk-dev] [PATCH v5 7/8] ethdev: support of multiple sizes of redirection table

[Helin Zhang]

As 40G NIC supports different sizes (128/512/64 entries) of redirection table
from that (128 entries) of 1G and 10G NICs, support of multiple sizes of
redirection table is needed. It includes,
* Redefine 'struct rte_eth_rss_reta' in ethdev.
  - To 'struct rte_eth_rss_reta_entry64' which contains 64 entries and 64 bits
    mask.
  - Array of above new structure can be used for any number of redirection
    table entries, as long as the number is multiple of 64. This is quite
    flexible for the future expanding of redirection table.
* Redefinition of relevant interfaces in ethdev.
  - Interface of reta update has been redefined with new parameters.
  - Interface of reta query has been redefined with new parameters.
* Rework of 1G PMD in igb.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 10G PMD in ixgbe.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 40G PMD (PF only) in i40e.
  - reta update has been reworked.
  - reta query has been reworked.
* Implement relevant commands in testpmd.

[dpdk-dev] [PATCH v6 0/8] support of multiple sizes of redirection table

[Helin Zhang]

As e1000, ixgbe and i40e hardware use different sizes of redirection
table in PF or VF, ethdev and PMDs need to be reworked to support
multiple sizes of that table. In addition, commands in testpmd also
need to be reworked to support these changes.

v2 changes:
* Reorganized the patches.
* Added code style fixes.
* Added support of reta updating/querying in i40e VF.

v3 changes:
* Reorganized the patch set.
* Added returning default RX/TX configurations in VF (igb/ixgbe/i40e),
  as the patch set of it for PF has been accepted recently.

v4 changes:
* Renamed RTE_BIT_WIDTH_64 to RTE_RETA_GROUP_SIZE.
* Added more comments to rte_eth_dev_rss_reta_update() and
  rte_eth_dev_rss_reta_query().

v5 changes:
* Reworked the annotations of macros of RETA sizes in rte_ethdev.h.

v6 changes:
* Checking if the input number of reta size is 64 aligned has been
  added in rte_ethdev.c.
* Use macros to replace numeric in all igb, ixgbe and i40e PMDs of
  updating/querying reta.

v2 changes:
* Added new function for ops of 'dev_infos_get' specifically for ixgbe VF.

v3 changes:
* Returning default RX/TX configurations has been added in ops of
  'dev_infos_get' for VF, as it was added recently in that for PF.

[dpdk-dev] [PATCH v6 6/8] i40e: rework of ops of 'dev_infos_get' for both PF and VF

[Helin Zhang]

Returning redirection table size has been supported in ops of
'dev_infos_get' for both PF and VF. Default RX/TX configurations
of VF can be returned in ops of 'dev_infos_get', while it was
missed before.

[dpdk-dev] [PATCH v6 7/8] ethdev: support of multiple sizes of redirection table

[Helin Zhang]

As 40G NIC supports different sizes (128/512/64 entries) of
redirection table from that (128 entries) of 1G and 10G NICs,
support of multiple sizes of redirection table is needed.
It includes,
* Redefine 'struct rte_eth_rss_reta' in ethdev.
  - To 'struct rte_eth_rss_reta_entry64' which contains 64
    entries and 64 bits mask.
  - Array of above new structure can be used for any number of
    redirection table entries, as long as the number is multiple
    of 64. This is quite flexible for the future expanding of
    redirection table.
* Redefinition of relevant interfaces in ethdev.
  - Interface of reta update has been redefined with new parameters.
  - Interface of reta query has been redefined with new parameters.
* Rework of 1G PMD in igb.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 10G PMD in ixgbe.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 40G PMD (PF only) in i40e.
  - reta update has been reworked.
  - reta query has been reworked.
* Implement relevant commands in testpmd.

Helin,

I fixed these errors before applying:

You should update your checkpatch, it checks more and more things.
It's really useful ;)

Hi Thomas

Thank you for the fixes! I am using the checkpatch.pl of kernel 3.6.10. Yes, It seems that I need to update it to a newer version.

Regards,
Helin

  Description: pmdrss_reta is designed to improve networking performance by load balancing the packets received from a NIC port to multiple NIC RX queues, with each queue handled by a different logical core.
  Command / instruction:
	#1. set up testpmd with fortville NICs::
  	./testpmd -c fffff -n %d -- -i --coremask=0xffffe --rxq=16 --txq=16

	#2. verbose configuration::
 	 testpmd command: set verbose 8
	
	#3. PMD fwd only receive the packets::
  	testpmd command: set fwd rxonly

	#4. Reta Configuration.  128 or 512 reta entries configuration::
  	testpmd command: port config 0 rss reta (hash_index,queue_id)
	
	#5. start packet receive::
  	testpmd command: start

  Expected test result:
The testpmd will print the hash value and actual queue of every packet.
#1. Calaute the queue id: hash value%128or512, then refer to the redirection table to get the theoretical queue id.
#2. The theoretical queue id is the same with the actual queue id.

Subject: [PATCH v6 0/8] support of multiple sizes of redirection table

As e1000, ixgbe and i40e hardware use different sizes of redirection table in PF or VF, ethdev and PMDs need to be reworked to support multiple sizes of that table. In addition, commands in testpmd also need to be reworked to support these changes.

v2 changes:
* Reorganized the patches.
* Added code style fixes.
* Added support of reta updating/querying in i40e VF.

v3 changes:
* Reorganized the patch set.
* Added returning default RX/TX configurations in VF (igb/ixgbe/i40e),
  as the patch set of it for PF has been accepted recently.

v4 changes:
* Renamed RTE_BIT_WIDTH_64 to RTE_RETA_GROUP_SIZE.
* Added more comments to rte_eth_dev_rss_reta_update() and
  rte_eth_dev_rss_reta_query().

v5 changes:
* Reworked the annotations of macros of RETA sizes in rte_ethdev.h.

v6 changes:
* Checking if the input number of reta size is 64 aligned has been
  added in rte_ethdev.c.
* Use macros to replace numeric in all igb, ixgbe and i40e PMDs of
  updating/querying reta.
