[dpdk-dev] [PATCH 00/51] ethdev: change rte_eth_dev_info_get() return value to int

[dpdk-dev] [PATCH 00/51] ethdev: change rte_eth_dev_info_get() return value to int

[Andrew Rybchenko]

It is the first patch series to get rid of void returning functions
in ethdev in accordance with deprecation notice [1].

The patch to change dev_infos_get callback prototype to allow driver
return error will follow.

[dpdk-dev] [PATCH 01/51] ethdev: change rte_eth_dev_info_get() return value to int

[Andrew Rybchenko]

From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.ru>

Change rte_eth_dev_info_get() return value from void to int and return
negative errno values in case of error conditions.

[dpdk-dev] [PATCH 02/51] app/testpmd: check status of getting ethdev info

[Andrew Rybchenko]

From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.ru>

Add eth_dev_info_get_print_err() which is a wrapper for
rte_eth_dev_info_get() printing error if rte_eth_dev_info_get()
fails and returning its status code.

I would prefer that the driver api callback change to return an
error and not add more log messages.

Or maybe this patch is temporary until you get there in the patchset.

Re: [dpdk-dev] [PATCH 00/51] ethdev: change rte_eth_dev_info_get() return value to int

This is a huge series, and I suggest to combine some of the work, and/or
break it up.

Additionally, this patch breaks the ring_pmd_autotest unit test, but I
didn't bisect it to find out where.

I can send patches for examples separately, but it will not help a lot.
I can squash changes in examples, but I think it is wrong since it would
make review harder - different maintainers and different practices to
handle error in different examples (and we tried to take it into account).

Other ideas?

Many thanks, we'll take a look.

Got it. We'll change hn_vf_info_merge() and hn_vf_info_get() to return
int in this patch, but the return value will be ignored hn_dev_info_get()
before the patch which changes dev_infos_get prototype to return int
(that patch will be huge since it should update all drivers at once, so
it is better to preparation here).

Thanks.

I believe that allowing PMDs to return -ENOTSUP is not a good idea.
At the moment, all PMDs provides this kind of information. It is not
always very reliable piece of information but for me, it is a piece of
gold I would not like to loose when configuring devices.

I think it should be mandatory for all PMDs to provide this function.
Another possible way, give a sane default contents of this structure.
But, please, do not return -ENOTSUP.

I agree that dev_infos_get() callback should be mandatory, but
what the function should do if the callback is not provided?
I think that a sane default contents is more harm than an error
(basically that's what we had before the patch).
Since the function may return error, caller should take it into
account anyway. Yes, some error codes could have special
handling, but default error handling is required in any case.

Thanks. So, the goal is "just" to replace void by int. This is what I
was missing...

One way would be to fail to register a PMD without that callback.
Such PMD driver would be simply wrong. This is what I mean by saying
"mandatory" - the callback MUST be provided.

DPDK could be so nice to provide a default callback named like
default_dev_infos_get_when_you_are_incompetent_pmd_author() returning
mostly zeros and some always "known metadata" like device pointer,
driver_name, ...

> I think that a sane default contents is more harm than an error
> (basically that's what we had before the patch).

Well, the dev info API is not in the best possible condition. And I
believe that this is not a secret. Especially, I am missing a kind of
specification of the structure contents (API doc is not satisfactory at
the moment). E.g. what does it mean when dev_info.max_rx_queues ==
65535? Similarly max_rx_pktlen == 65535. IMHO, this is the source of
harm - no spec. Let's return back to the thread topic.

For me, at the application level, I need to get at least identification
of the device - bus name, driver name, device ID. The dev info
structure gives me those. If there is a better way to retrieve these
info by port_id then I have no objections to allow to return -ENOTSUP.
However, the only well-defined way seems to be rte_eth_dev_info_get().
If a PMD does not give it to me, such PMD becomes simply useless.

I am currently experiencing 2 different PMDs and both provide slightly
different semantics of the dev info structure. That is bad, of course.
However, I can stand it if I know some info about the device -
as I've already mentioned: ID, driver and bus.

You are absolutely right and I support such changes.

Hrrm?  Not sure what you mean.

Patches should be broken up by logical change.  That way, it is easy to
bisect and isolate what has changed.  This series, it seems like there's
a single logical change, and that's been spread over lots of patches.

I think grouping all the examples and all the app/test together, would
make the series 14 review-able patches.  As it is, stepping through 40+
10-line emails is much more tedious (not to mention needing to apply
them, check each for build, etc).

This is actually what I'm more concerned about anyway.  Please do
address this.

I mean that it is easier to review many small patches than one huge patch
especially when these files are maintained by different people.

Single huge patch is worse for both bisect and review. When patch is huge
and bisect says that the patch is guilty, you still need to find out which
snippet/change is guilty.

In this particular case nothing prevents to split the patch make it easier
to review and bisect.

Yes, less build cycles are required for smaller number of patches, but
anyway automation does (should do) it. So, not that important.

I disagree that it is easier to review one huge patch. Sorry.
I think it is important here that different examples are maintained
by different people. Anyway if more reviewers will support the idea
to squash examples into once patch, technically it is trial to do.

Typically callbacks are set on probe and
rte_eth_dev_pci_generic_probe() and similar functions could
be updated to reject devices with missing dev_infos_get callback.
However, there is a secondary process cases where dev_infos_get
is not essential since control path may be unsupported in secondary
process.

Anyway, I think it is a separate story.

I like the idea of making some functions mandatory.
If we need to provide a default callback, why not.

I'm also thinking we need to better enforce a standardization
of basic features to be implemented. It would make DPDK more mature.

When doing same kind of change on multiple applications,
splitting patches won't help any bisect (they are all different
applications anyway). And I think squashing can better show the idea that
every applications got the same kind of change (thanks for that).
In general, I think patches deserve to be split when there is something
interesting to say in the commit log. If you want to describe a
different logic of each app, why not. The other way is to explain
some exceptions for some applications in a signle patch.

My conclusion is that it is often hard to find the good balance,
between split and squash, and I can understand any motivation :)
Sometimes I squash some patches on apply after they got all reviewed
separately. In this case, I didn't look yet :)

+1 to make some dev_ops mandatory. At first I can think of:
dev_infos_get
dev_configure
rx_queue_setup
tx_queue_setup
dev_start
dev_stop

specific to 'dev_infos_get', it is to get device info, not sure a default
callback is good idea for it.

And overall agree that 'rte_eth_dev_info_get()' can be documented more/better ...

It should be in different most probably, but the 'memset' before
'rte_eth_dev_info_get()' looks redundant, since API does the same.

Should we check the return value here too? And return 'dev_info' immediately on
error instead of going on.

What do you think 'rte_exit()' here instead of 'return', 'init_config()' doesn't
return error, and returning from init will assume everyting setup, 0 number of
queues for any port eventually will cause an exit in the app, better to fail
where error occurs.

I would like to get this early if possible, before end of this week when I
expect there will be a peak of patches before the deadline.

Overall patchset looks good to me, only one comment on the testpmd one, it also
passes automated builds/checks (including patch by patch builds).
(ring_pmd_autotest needs to be fixed of course)

For the patchset, I agree with Andrew's argument, yes logically same change and
apps/examples/tests can be merged into single commit but it would be big &
harder to review. Since it is already split, for me it looks good as it is.

Thanks, missed it.

Also there are two more cases in testpmd to get maximum number
of Rx/Tx queue. I'll skip port and continue if device info get fails.

I agree. I've considered to skip the port and continue with other port, but
it is better to catch such problems earlier instead of hiding behind complex
logic.

+1 as well, but I think it is a separate story.
I really don't want to complicate so big patchset by introducing
more logic here.

As far as I can see dev_infos_get callback is implemented in
all network PMDs. So, I think the topic is not gating the patchset.

Thanks a lot, makes sense and I agree with explanations.
The only problem is review of such huge patches, when
reviewer needs to find out his snippet. Also split version
is better for patchwork reviewed/acked counters. It is
clear which snippets are reviewed, which are not.
Unfortunately split does not help this patchset to get
more attention from reviewers :(

[dpdk-dev] [PATCH v2 00/54] ethdev: change rte_eth_dev_info_get() return value to int

[Andrew Rybchenko]

It is the first patch series to get rid of void returning functions
in ethdev in accordance with deprecation notice [1].

Functions which return void are bad since they do not provide explicit
information to the caller if everything is OK or not. It was bugs in
rte_eth_dev_info_get() recently which kept device information
uninitialized if port ID is invalid.

The patch series updates rte_eth_dev_info_get() straightforward
to simply return error if port ID is invalid or driver does not
provide corresponding callback. In the future default callback
which fills in generic non driver specific information could be
added to help secondary processes cases when driver has no
callback in secondary process. Also the idea to make the callback
mandatory should be considered.

Patches to update examples are kept separately to simplify review,
but could be squashed on apply since logically it is the same
change in all applicable examples.

v2:
 - add a patch to change dev_infos_get prototype to return int as well
 - fix issue with ring_pmd_autotest (just inverted assert condition)
 - add missing net/failsafe patch
 - fix net/netsvc patch in accordance with review notes from Stephen
 - fix app/testpmd patch in accordance with review notes from Ferruh
 - add net/bnxt ack

[dpdk-dev] [PATCH v2 02/54] ethdev: change rte_eth_dev_info_get() return value to int

[Andrew Rybchenko]

From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.com>

Change rte_eth_dev_info_get() return value from void to int and return
negative errno values in case of error conditions.
Modify rte_eth_dev_info_get() usage across the ethdev according
to new return type.

[dpdk-dev] [PATCH v2 03/54] app/testpmd: check status of getting ethdev info

[Andrew Rybchenko]

From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.com>

Add eth_dev_info_get_print_err() which is a wrapper for
rte_eth_dev_info_get() printing error if rte_eth_dev_info_get()
fails and returning its status code.

At least, hopefully the reviewer knows from the changestat what to look
for to narrow it down.

That's a problem for which I have no solution.  If you solve it please

Re: [dpdk-dev] [PATCH v2 14/54] net/failsafe: check status of getting ethdev info

[Gaëtan Rivet]

Hello Andrew, Ivan,

I would have found more consistent merging this patch with the main
ethdev one. It is short enough, I'm not sure this warrants a patch on
its own.

In any case,

Okay.  This ends up getting confusing to write automation around.  I
know UNH uses some scripts to figure out whether a particular patch

Meanwhile, I'll try to manually rebase the series so that we have a
clean run.

'dev->data->dev_conf' should be restored from 'orig_conf' on failure, before return.

Should API use "return eth_err(port_id, ret);" syntax, as other APIs do,
I am not very clear about the 'eth_err()', Thomas can provide better
description/suggestion on this.

This is 'get_mac_addr_index()' static function, and it should either send
negative value for error, or 'index' value in case of success. So should we be
sure here only negative value sent? Incase 'rte_eth_dev_info_get()' returns
positive value in the future.

Same comment as above, for this 'get_hash_mac_addr_index()' static function.

[dpdk-dev] [PATCH v3 00/54] ethdev: change rte_eth_dev_info_get() return value to int

[Andrew Rybchenko]

It is the first patch series to get rid of void returning functions
in ethdev in accordance with deprecation notice [1].

Functions which return void are bad since they do not provide explicit
information to the caller if everything is OK or not. It was bugs in
rte_eth_dev_info_get() recently which kept device information
uninitialized if port ID is invalid.

The patch series updates rte_eth_dev_info_get() straightforward
to simply return error if port ID is invalid or driver does not
provide corresponding callback. In the future default callback
which fills in generic non driver specific information could be
added to help secondary processes cases when driver has no
callback in secondary process. Also the idea to make the callback
mandatory should be considered.

Patches to update examples are kept separately to simplify review,
but could be squashed on apply since logically it is the same
change in all applicable examples.

[1] https://patches.dpdk.org/patch/56969/

v3:
 - add acks received on v2 patches
 - fix callback patch to take callback return value into account
 - use newer Git version to generate easier to review patches
 - return -1 from get_mac_addr_index() and get_hash_mac_addr_index()
 - rollback dev_conf in the case of rte_eth_dev_info_get() failure

v2:
 - add a patch to change dev_infos_get prototype to return int as well
 - fix issue with ring_pmd_autotest (just inverted assert condition)
 - add missing net/failsafe patch
 - fix net/netsvc patch in accordance with review notes from Stephen
 - fix app/testpmd patch in accordance with review notes from Ferruh
 - add net/bnxt ack

[dpdk-dev] [PATCH v3 03/54] app/testpmd: check status of getting ethdev info

[Andrew Rybchenko]

From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.com>

Add eth_dev_info_get_print_err() which is a wrapper for
rte_eth_dev_info_get() printing error if rte_eth_dev_info_get()
fails and returning its status code.

[dpdk-dev] [PATCH v3 14/54] net/failsafe: check status of getting ethdev info

[Andrew Rybchenko]

From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.ru>

rte_eth_dev_info_get() return value was changed from void to
int, so this patch modify rte_eth_dev_info_get() usage across
net/failsafe according to its new return type.
