[PATCH v3 0/2] add callbacks for VF management

[PATCH v3 0/2] add callbacks for VF management

[Bernard Iremonger]

This patchset contains new callback functions requested by AT&T for use
with the Virtual Function Daemon (VFD).

Two new callback functions have been added.
Changes have been made to the ixgbe_rcv_msg_from_vf function to
use the callback functions.

This patchset depends on the following patch.
http://dpdk.org/dev/patchwork/patch/16296/
[dpdk-dev,v6,1/2] net/ixgbe: add API's for VF management

These patches were part of the RFC PATCH v2 of the above patchset,
but were dropped from the v3 patchset.

Changes in v3:
rebase to latest master
submitted as a seperate patchset.
Moved the response enums from the ethdev to the ixgbe PMD.

[PATCH v3 1/2] librte_ether: add internal callback functions

[Bernard Iremonger]

add _rte_eth_dev_callback_process_vf function.
add _rte_eth_dev_callback_process_generic function

Adding a callback to the user application on VF to PF mailbox message,
allows passing information to the application controlling the PF
when a VF mailbox event message is received, such as VF reset.

[PATCH v3 2/2] net/ixgbe: add callback to user app on VF to PF mbox msg

[Bernard Iremonger]

call _rte_eth_dev_callback_process_vf from ixgbe_rcv_msg_from_vf function.

The callback asks the user application if it is allowed to perform
the function.
If the cb_param.retval is RTE_PMD_IXGBE_MB_EVENT_PROCEED then continue,
if 0, do nothing and send ACK to VF
if > 1, do nothing and send NAK to VF.

Re: [PATCH v3 1/2] librte_ether: add internal callback functions

[Stephen Hemminger]

I know callbacks are needed, in fact even more are necessary. That is why
I  don't like this design. It expands the API for each event. I think
something like the Linux kernel netlink callback mechanism that passes an
event and device handle.

Subject: Re: [dpdk-dev] [PATCH v3 1/2] librte_ether: add internal callback functions


I know callbacks are needed, in fact even more are necessary. That is why I  don't like this design. It expands the API for each event. I think something like the Linux kernel netlink callback mechanism that passes an event and device handle.

The current  rte_eth_dev_callback_register()  function takes a parameter void *cb_arg. This allows the passing of a parameter to the callback. For the events RTE_ETH_EVENT_QUEUE_STATE,  RTE_ETH_EVENT_INTR_RESET the callback parameter is not used. In some cases for the RTE_ETH_EVENT_INTR_LSC the call back parameter is used.

This patch adds a new event RTE_ETH_VF_MBOX and a parameter for this event struct rte_eth_mb_event_param{}. This parameter is only used with the RTE_ETH_VF_MBOX event and does not affect the other events.

The struct rte_eth_mb_event_param{} should probably not be in rte_eth_dev.h, I will send a v4.

Regards,

Bernard.

[PATCH v4 0/2] add callbacks for VF management

[Bernard Iremonger]

This patchset contains new callback functions intended for VF management.

Two new callback functions have been added.
Changes have been made to the ixgbe_rcv_msg_from_vf function to
use the callback functions.

This patchset depends on the following patch.
http://dpdk.org/dev/patchwork/patch/16296/

These patches were part of the RFC PATCH v2 of the above patchset,
but were dropped from the v3 patchset.

Changes in v4:
Rebased to latest master.
Moved the callback parameter structure from the ethdev to the ixgbe PMD.

Changes in v3:
Rebased to latest master.
Submitted as a seperate patchset.
Moved the response enums from the ethdev to the ixgbe PMD.

[PATCH v4 2/2] net/ixgbe: add callback to user app on VF to PF mbox msg

[Bernard Iremonger]

call _rte_eth_dev_callback_process_vf from ixgbe_rcv_msg_from_vf function.

The callback asks the user application if it is allowed to perform
the function.
If the cb_param.retval is RTE_PMD_IXGBE_MB_EVENT_PROCEED then continue,
if 0, do nothing and send ACK to VF
if > 1, do nothing and send NAK to VF.

I have some difficulties to parse this explanation.
Please could you reword it and precise the direction of the message
and the use case context?

This function is just adding a parameter, compared to the legacy
_rte_eth_dev_callback_process.
Why calling it process_vf?
And by the way, why not just replacing the legacy function?
As it is a driver interface, there is no ABI restriction.

Either we choose to have a "generic" VF event well documented,
or it is just a specific event with a tip on where to find the doc.
Here we need at least to know how to handle the argument.

This is really an internal function and should not be exported at all.

I will reword the explanation and add use case context.

The parameter is just being added for the VF event, the handling of the other events is unchanged.

I thought there would be an ABI issue if the legacy function is replaced.
The _rte_eth_dev_callback_process is exported in DPDK 2.2 and used in the following PMD's, lib and app:

app/test/virtual_pmd
drivers/net/e1000
drivers/net/ixgbe
drivers/net/mlx5
drivers/net/vhost
drivers/net/virtio
lib/librte_ether

 Adding a parameter to _rte_eth_dev_callback_process()  will impact all of the above.
Will this cause an ABI issue?

It is a specific event for VF to PF messages, details on the function and arguments are in the rte_ethdev.h file.

Both new functions are internal I  will make them static and remove them from the map file.
When the functions are made static, should the function declarations be moved from rte_ethdev.h to rte_ethdev.c ?

Thanks for the review.

Regards,

Bernard.

No because ABI is for applications (Application Binary Interface).
Here you are just changing the driver interface. And we have no commitment
to maintain the compatibility of this interface for external drivers.

No I think it is only explained in the ixgbe code.

[PATCH v5 00/13] modify callback for VF management

[Bernard Iremonger]

This patchset modifies the callback function for VF management.

A third parameter has been added to the _rte_eth_dev_callback_process
function. All references to this function have been updated.
Changes have been made to the ixgbe_rcv_msg_from_vf function to
use the new callback parameter.

This patchset depends on the following patch.
http://dpdk.org/dev/patchwork/patch/16296/
[dpdk-dev,v6,1/2] net/ixgbe: add API's for VF management

These patches were part of the RFC PATCH v2 of the above patchset,
but were dropped from the v3 patchset.

Changes in v5:
Rebased to latest master.
Added parameter to the _rte_eth_dev_callback_process function
Removed two new callback functions which were added previously.
Updated all calls to the _rte_eth_dev_callback_process function.

Changes in v4:
Rebased to latest master.
Moved the callback parameter structure from the ethdev to the ixgbe PMD.

Changes in v3:
Rebased to latest master.
Submitted as a seperate patchset.
Moved the response enums from the ethdev to the ixgbe PMD.

Changes in v2:
Rebased to latest master.

[PATCH v5 01/13] librte_ether: modify internal callback function

[Bernard Iremonger]

add parameter to the _rte_eth_dev_callback_process function.

Adding a parameter to this function allows passing information
to the application when an eth device event occurs such as
a VF to PF message.
This allows the application to decide if a particular function
is permitted.

[Bernard Iremonger]

call _rte_eth_dev_callback_process from ixgbe_rcv_msg_from_vf function.

The callback asks the user application if it is allowed to perform
the function.
If the cb_param.retval is RTE_PMD_IXGBE_MB_EVENT_PROCEED then continue,
if 0, do nothing and send ACK to VF
if > 1, do nothing and send NAK to VF.

You need to squash the patches updating the calls to this function.
Otherwise, this patch does not compile.

[...]
> +		if (param != NULL)
> +			dev_cb.cb_arg = (void *) param;

You are overriding the user parameter.
As it is only for a new event, it can be described in the register API
that the user param won't be returned for this event.
But a better design would be to add a new parameter to the callback.
However it will be an API breakage.

> +	RTE_ETH_EVENT_VF_MBOX,  /**< PF mailbox processing callback */

Sorry I do not parse well this line.
The event name is VF_MBOX and the comment is about the callback
processing this event on PF side?
I would suggest this kind of comment: "message from VF received by PF"

[...]

In a more generic case, the parameter gives some details about the event.

Yes, we want to update the user parameter for the RTE_ETH_EVENT_VF_MBOX

I will add a description in the rte_eth_dev_callback_register  function.

I do not want to break the ABI at this point.

No you can keep a separate patch for the VF event in ixgbe.

Yes, but it can be considered for a later change.

I have 4 patches at present

librte_ether
net/ixgbe
drivers/net
app/test

Would this be acceptable or do you just want  everything squashed into librte_ether except for net/ixgbe?

I have renamed param to cb_arg to make it clearer what is happening.

You can test the compilation of each patch with this command:
	git rebase -i origin/master -x scripts/test-build.sh
or just:
	git rebase -i origin/master -x make

I think you need to squash drivers/net (adding just NULL param) and
app/test in ethdev patch.

They do not compile if applied one by one.
Ok, I will squash drivers/net and app/test into the librte_ether patch.

[PATCH v6 0/2] modify callback for VF management

[Bernard Iremonger]

This patchset modifies the callback function for VF management.

A third parameter has been added to the _rte_eth_dev_callback_process
function. All references to this function have been updated.
Changes have been made to the ixgbe_rcv_msg_from_vf function to
use the new callback parameter.

This patchset depends on the following patch.
http://dpdk.org/dev/patchwork/patch/16296/
[dpdk-dev,v6,1/2] net/ixgbe: add API's for VF management

These patches were part of the RFC PATCH v2 of the above patchset,
but were dropped from the v3 patchset.

Changes in v5:
Rebased to latest master.
Squashed patches down to two patches.
Renamed parameter to _rte_eth_dev_callback_process function.
Updated API descriptions.

Changes in v5:
Rebased to latest master.
Added parameter to the _rte_eth_dev_callback_process function
Removed two new callback functions which were added previously.
Updated all calls to the _rte_eth_dev_callback_process function.

Changes in v4:
Rebased to latest master.
Moved the callback parameter structure from the ethdev to the ixgbe PMD.

Changes in v3:
Rebased to latest master.
Submitted as a seperate patchset.
Moved the response enums from the ethdev to the ixgbe PMD.

Changes in v2:
Rebased to latest master.

[PATCH v6 1/2] librte_ether: modify internal callback function

[Bernard Iremonger]

add cb_arg parameter to the _rte_eth_dev_callback_process function.

Adding a parameter to this function allows passing information
to the application when an eth device event occurs such as
a VF to PF message.
This allows the application to decide if a particular function
is permitted.

drivers/net: add parameter to callback process function

add parameter to call of _rte_eth_dev_callback_process function
in the following PMD's:

net/bonding
net/e1000
net/i40e
net/mlx4
net/mlx5
net/nfp
net/thunderx
net/vhost
net/virtio
net/enic

app/test: add parameter to callback process function
add parameter to call of _rte_eth_dev_callback_process function

[PATCH v6 2/2] net/ixgbe: add callback to user app on VF to PF mbox msg

[Bernard Iremonger]

call _rte_eth_dev_callback_process from ixgbe_rcv_msg_from_vf function.

The callback asks the user application if it is allowed to perform
the function.
If the cb_param.retval is RTE_PMD_IXGBE_MB_EVENT_PROCEED then continue,
if 0, do nothing and send ACK to VF
if > 1, do nothing and send NAK to VF.

This comment is wrong.
You should say that the user data is overwritten in the case of
RTE_ETH_EVENT_VF_MBOX. And you should point to where the meaning
of this parameter is documented (ixgbe.h) or document it here.

[PATCH v7 0/2] modify callback for VF management

[Bernard Iremonger]

This patchset modifies the callback function for VF management.

A third parameter has been added to the _rte_eth_dev_callback_process
function. All references to this function have been updated.
Changes have been made to the ixgbe_rcv_msg_from_vf function to
use the new callback parameter.

This patchset depends on the following patch.
http://dpdk.org/dev/patchwork/patch/16430/
[dpdk-dev,v7,1/2] net/ixgbe: add API's for VF management

These patches were part of the RFC PATCH v2 of the above patchset,
but were dropped from the v3 patchset.

Changes in v7:
Rebased to latest master.
Move references to _rte_eth_dev_callback_process in ixgbe patch
to librte_ether patch.
Revised description of callback parameter.

Changes in v6:
Rebased to latest master.
Squashed patches down to two patches.
Renamed parameter to _rte_eth_dev_callback_process function.
Updated API descriptions.

Changes in v5:
Rebased to latest master.
Added parameter to the _rte_eth_dev_callback_process function
Removed two new callback functions which were added previously.
Updated all calls to the _rte_eth_dev_callback_process function.

Changes in v4:
Rebased to latest master.
Moved the callback parameter structure from the ethdev to the ixgbe PMD.

Changes in v3:
Rebased to latest master.
Submitted as a seperate patchset.
Moved the response enums from the ethdev to the ixgbe PMD.

Changes in v2:
Rebased to latest master.

[PATCH v7 1/2] librte_ether: modify internal callback function

[Bernard Iremonger]

add cb_arg parameter to the _rte_eth_dev_callback_process function.

Adding a parameter to this function allows passing information
to the application when an eth device event occurs such as
a VF to PF message.
This allows the application to decide if a particular function
is permitted.

drivers/net: add parameter to callback process function

add parameter to call of _rte_eth_dev_callback_process function
in the following PMD's:

net/bonding
net/e1000
net/i40e
net/enic
net/ixgbe
net/mlx4
net/mlx5
net/nfp
net/thunderx
net/vhost
net/virtio

app/test: add parameter to callback process function

[PATCH v7 2/2] net/ixgbe: add callback to user app on VF to PF mbox msg

[Bernard Iremonger]

call _rte_eth_dev_callback_process from ixgbe_rcv_msg_from_vf function.

The callback asks the user application if it is allowed to perform
the function.

If the cb_param.retval is RTE_PMD_IXGBE_MB_EVENT_PROCEED then continue,
if 0, do nothing and send ACK to VF
if > 1, do nothing and send NAK to VF.

This is corrected in the v7 patchset.

Generally speaking, the user data is a pointer passed by the application
when registering the callback and must be untouched.
It should be the name of the parameter that you are overriding with
this structure.
So this "userdata" pointer could probably be better defined.

By the way, it is far from trivial to understand how to write the callback.
I think it deserves more explanations.

OK, this is probably a temporary solution.
I am OK to let it enter in DPDK 16.11 and starts some discussions.
That's why I'll try to sum up the situation for this patchset and
the other one (API for VF management).

The VF features are not yet enough standardized.
So the functions to manage them from the PF will be in some specific
headers (drivers/net/ixgbe/rte_pmd_ixgbe.h in this case).
They could be promoted in the generic ethdev API if it appears to be
generic enough.
There can be also some application callbacks called from the drivers
with a specific signature:
	- a "generic" event type for VF
	- a specific parameter defined in the driver
Obviously, we cannot have different meanings of this event depending
on the driver in use. So we must have something more robust when
implementing such feature in a second driver.

As there is no obvious solution, the pragmatic approach is to
accept this first specific implementation while waiting for a better idea.

I will clarify the description of the struct  rte_pmd_ixgbe_mb_event_param, and rename the member userdate to msg in a v8 patchset.

[PATCH v8 0/2] modify callback for VF management

[Bernard Iremonger]

This patchset modifies the callback function for VF management.

A third parameter has been added to the _rte_eth_dev_callback_process
function. All references to this function have been updated.
Changes have been made to the ixgbe_rcv_msg_from_vf function to
use the new callback parameter.

This patchset depends on the following patch.
http://dpdk.org/dev/patchwork/patch/16430/
[dpdk-dev,v7,1/2] net/ixgbe: add API's for VF management

These patches were part of the RFC PATCH v2 of the above patchset,
but were dropped from the v3 patchset.

Changes in v8:
Rebased to latest master.
Improve description of struct rte_pmd_ixgbe_mb_event_param,
rename  member user_data to msg.

Changes in v7:
Rebased to latest master.
Move references to _rte_eth_dev_callback_process in ixgbe patch
to librte_ether patch.
Revised description of callback parameter.

Changes in v6:
Rebased to latest master.
Squashed patches down to two patches.
Renamed parameter to _rte_eth_dev_callback_process function.
Updated API descriptions.

Changes in v5:
Rebased to latest master.
Added parameter to the _rte_eth_dev_callback_process function
Removed two new callback functions which were added previously.
Updated all calls to the _rte_eth_dev_callback_process function.

Changes in v4:
Rebased to latest master.
Moved the callback parameter structure from the ethdev to the ixgbe PMD.

Changes in v3:
Rebased to latest master.
Submitted as a seperate patchset.
Moved the response enums from the ethdev to the ixgbe PMD.

Changes in v2:
Rebased to latest master.

[PATCH v8 1/2] librte_ether: modify internal callback function

[Bernard Iremonger]

add cb_arg parameter to the _rte_eth_dev_callback_process function.

Adding a parameter to this function allows passing information
to the application when an eth device event occurs such as
a VF to PF message.
This allows the application to decide if a particular function
is permitted.

drivers/net: add parameter to callback process function

add parameter to call of _rte_eth_dev_callback_process function
in the following PMD's:

net/bonding
net/e1000
net/i40e
net/enic
net/ixgbe
net/mlx4
net/mlx5
net/nfp
net/thunderx
net/vhost
net/virtio

app/test: add parameter to callback process function
add parameter to call of _rte_eth_dev_callback_process function

[PATCH v8 2/2] net/ixgbe: add callback to user app on VF to PF mbox msg

[Bernard Iremonger]

call _rte_eth_dev_callback_process from ixgbe_rcv_msg_from_vf function.

The callback asks the user application if it is allowed to perform
the function.

If the cb_param.retval is RTE_PMD_IXGBE_MB_EVENT_PROCEED then continue,
if 0, do nothing and send ACK to VF
if > 1, do nothing and send NAK to VF.

[PATCH v8 0/2] add API's for VF management

[Bernard Iremonger]

This patchset contains new DPDK API's for use
with the Virtual Function Daemon (VFD).

The need to configure and manage VF's on a NIC has grown to the
point where a DPDK based tool, VFD, has been developed to do this.

This patch set adds API extensions to DPDK for VF configuration.

Eight new API's have been added for the Intel 82559 NIC.

Changes have been made to testpmd to facilitate testing of the new API's.
The testpmd documentation has been updated to document the testpmd changes.

Changes in v8:
rebase to latest master branch.
add new API's to testpmd help command.
modify testpmd  Makefile to build with and without ixgbe PMD,
in shared library mode and default mode.

Changes in v7:
rebase to latest master branch.
minor changes to ixgbe PMD following internal review.

Changes in v6:
rebase to latest master branch.
fix ixgbe makefile.
move set_vf_vlan_stripq function from ethdev to ixgbe PMD.
revise testpmd command for set_vf_vlan_stripq.

Changes in v5:
rebase to latest master branch.
remove new API's from eth_dev_ops structure.
add public API's to ixgbe PMD.
revise testpmd commands for new API's

Changes in v4:
The rte_eth_dev_vf_ping API has been dropped as it is a work around for a bug.
The rte_eth_dev_set_vf_vlan_strip API has been renamed to
rte_eth_dev_set_vf_vlan_stripq.

Changes in v3:
rebase to latest master branch.
drop patches for callback functions
revise VF id checks in new librte_ether functions
revise testpmd commands for new API's

Changes in V2:
rebase to latest master branch.
fix compile  error with clang.

Sorry if I miss something, but I thought it was enough to do:
LDLIBS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += -lrte_pmd_ixgbe

No unfortunately not, the above line does not work for all scenarios .

There are 4 scenarios as follows:

CONFIG_RTE_LIBRTE_IXGBE_PMD=y  with CONFIG_RTE_BUILD_SHARED_LIB=n

CONFIG_RTE_LIBRTE_IXGBE_PMD=y  with CONFIG_RTE_BUILD_SHARED_LIB=y

CONFIG_RTE_LIBRTE_IXGBE_PMD=n  with CONFIG_RTE_BUILD_SHARED_LIB=y

CONFIG_RTE_LIBRTE_IXGBE_PMD=n  with CONFIG_RTE_BUILD_SHARED_LIB=n

I have been doing quite a bit of building today to get it to work in all 4 scenarios.

Regards,

Bernard.

I have a doubt about the tests because LDLIBS-y does not exist.
There is _LDLIBS-y and LDLIBS.
But in the static case, you wrote:
	LDLIBS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += -lrte_pmd_ixgbe endif
Please could you check?

LDLIBS-y exists in some of the scenarios but not all.
Do you want me to check the four scenarios  with just the line below.

LDLIBS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += -lrte_pmd_ixgbe

I think I'm something obvious.
Please could you point the line where LDLIBS-y is used?

Line 62  of latest Makefile;
LDLIBS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += -lrte_pmd_ixgbe

LDLIBS-y does not exist when CONFIG_RTE_BUILD_SHARED_LIB=y

No, I mean where do you find LDLIBS- (without underscore) before your patch?
git grep '\<LDLIBS-' returns nothing.

Before my patch LDLIBS was not used in the testpmd Makefile.

The linking was done in rte.app.mk, this uses LDLIBS and _LDLIBS-y.
I don't see LDLIBS-y either.

[PATCH v9 0/2] add API's for VF management

[Bernard Iremonger]

This patchset contains new DPDK API's for use
with the Virtual Function Daemon (VFD).

The need to configure and manage VF's on a NIC has grown to the
point where a DPDK based tool, VFD, has been developed to do this.

This patch set adds API extensions to DPDK for VF configuration.

Eight new API's have been added for the Intel 82559 NIC.

Changes have been made to testpmd to facilitate testing of the new API's.
The testpmd documentation has been updated to document the testpmd changes.

Changes in v8:
rebase to latest master branch.
fix testpmd Makefile.

Changes in v8:
rebase to latest master branch.
add new API's to testpmd help command.
modify testpmd  Makefile to build with and without ixgbe PMD,
