[dpdk-dev] [RFC] doc: change to diverse and inclusive language

[dpdk-dev] [RFC] doc: change to diverse and inclusive language

[Stephen Hemminger]

For diversity reasons, the DPDK should take every effort
to eliminate master and slave terminology. The actual code change
is just syntax, but it has bigger impacts.

Lets announce this now and do it in the next API changing
release.

[dpdk-dev] [RFC] replace master/slave with primary/secondary

[Stephen Hemminger]

I have a full patch that replaces the master/slave lcore
naming (widely used in DPDK) with a better primary/secondary naming.

For now this is just a trial balloon to see what the impact would
look like. The change mostly automated so likely that things
are broken.

It is hard to break a change like this down, and still
keep git bisection clean.

It keeps rte_master_lcore_id and RTE_FOREACH_SLAVE as deprecated
items so that user code can still be built but they will be motivated
to change.

Here is a sample of what it would look like:

I think PRIMARY is a poor choice to describe the control thread. PRIMARY
is often used to designate the active element currently doing the work.
SECONDARY threads are also active threads doing equal dataplane work.

Another issue I see with primary / secondary is the ambiguity with
multi-process in DPDK. Doc readers could get confused about where a
primary / secondary thread is executed.

I think we could use instead DPDK-specific terminology. The lcore
organization is a little specific, with an lcore that does most init work
and spawns the others, but then runs the application like all others.

I'd propose instead leader lcore - there is this idea that the leader
is still a member of the team and will participate in the work.

Leader / worker?

I personally doubt such changes are needed at all.
Code churn will be massive for both DPDK itself and related user projects.
With no real gain in return, from my perspective.

Your concern is valid but the issue does need to be addressed.
If now when? This is as a good a time as any to do it.

Increasing diversity and inclusion is an overarching goal of many organizations
include my employer(Microsoft), the parent organization of DPDK(LF)
and my values.

Following values is more important than minor replacement of text in API.

I feel like Konstantin is correct here.

If we were using these terms for humans or groups of humans, then I would agree they should be changed. We need to take into account the context of the reference to these words. I agree some words should never be used in any context, but these terms are very reasonable in the context of DPDK and networking.

If everyone wants to accept the code churn (and it will effect a large number of applications, plus back porting will be more difficult IMO), then we can do it.

Have to disagree, the words matter. This has been discussed many times.

You chopped off my last sentence in your reply.

 "If everyone wants to accept the code churn (and it will effect a large number of applications, plus back porting will be more difficult IMO), then we can do it."

So to be clear, I am not opposed to making this change, but wanted to point out the technical impacts of this change to DPDK as a whole.

Thanks, my editing was not intended to be a way to stifling your response.
How many applications try to support multiple DPDK major versions at once?

NP, I understand it was not intended, but wanted to make sure it was not lost.

In Pktgen I try to support back to 18.11 release and some have asked for 18.04, one asked for 16.04 :-) I most likely do not do it very well, but I try given the limited time I have.

The big churn happened in 19.05 I think when all of the APIs and defines changed. It took me a few days to create a compat file to support backward compatibility .

I try to tell everyone I only support the latest release of DPDK and latest release of Pktgen, but that does not fly very well for some customers.

I would hope we can make this change and create methods to allow for supporting backward compatibility without every application having to create the compatibility support themselves.

Let me know how I can help,

Thanks

No sure I like the term "Leader" for a thread, but "worker" is an ok name.
How about "init thread" and "worker threads"?

Init was actually my first idea :) . I thought leader could be more
palatable in some documentation, but after some tests I think init
thread could work better after all.

I was thinking init / spawned threads first, but worker is ok.

Looking at Django the chose leader/follower.

Other alternatives are:

	hive/drone

	conductor/doer

Okay.

Usually, I am resistant to API/ABI changes - but actually in this case,
I think we can do this even *now* without breaking the ABI (IIUC, we can
use alias to keep around the old 'functions' - even structures shouldn't
have any change).  The API, we can carry over the existing stuff, and
flag it in documentation as deprecated.

[dpdk-dev] [RFC v2 00/26] Change references to master/slave to

[Stephen Hemminger]

This set of patches changes the API and conventions around referring
to DPDK lcores. The first patch changes rte_get_master_lcore_id
and related calls. The rest fix the DPDK to use the new naming.

The last patch marks the old names as deprecated.
My preferred option would be to do the rest of the patches now,
and hold the last one until 20.11

Buried in the documentation set are a couple of patches where
we were using incorrect naming around primary/secondary process.

This will could/should be flagged as an API policy violation
since new API is jumping the queue of EXPERIMENTAL. But we can
vote on the exception.

Stephen Hemminger (26):
  eal: rename terms used for DPDK lcores
  kni: fix reference to master/slave process
  bbdev: rename master to initial lcore

[dpdk-dev] [RFC v2 01/26] eal: rename terms used for DPDK lcores

[Stephen Hemminger]

Replace the old use of master/slave lcore with more inclusive
name of initial/secondary lcore.  The old visible API will
stay for now.

Change master2slave to new init2worker and vice-versa.

This patch breaks the expected practice for new API's.
The new rte_get_initial_lcore() will not go through the standard
experimental API phase; there is no functional difference
from the previous name.

Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>

This patch needs some rebasing as some of the memory functions have moved
from eal_memory.c to eal_common_dynmem.c, and the windows code has been
updated too.

Any further versions of this set can probably have the "RFC" label removed
too, as the consensus very much seems to be in favour of this change - it's
just a matter of getting the implementation in.

One further comment below.

For completeness sake, these variable names, which appear in multiple
places should be renamed too, m2s -> i2w, s2m -> w2i.

[dpdk-dev] [RFC v2 02/26] kni: fix reference to master/slave process

[Stephen Hemminger]

Use of old RTE_LCORE_FOREACH_SLAVE and rte_get_master_lcore_id()
are marked as deprecated.

All uses of these in DPDK itself is gone. This will cause warnings
for applications still using them.

[dpdk-dev] [PATCH v3 00/27] Replace references to master and slave

[Stephen Hemminger]

This set of patches changes the API and conventions around referring
to DPDK lcores. The first patch changes rte_get_master_lcore_id
and related calls. The rest fix the DPDK to use the new naming.

Buried in the documentation set are a couple of patches where
we were using incorrect naming around primary/secondary process.

This will could/should be flagged as an API policy violation
since new API is jumping the queue of EXPERIMENTAL. But we can
vote on the exception.

The one area left to be fixed is the bonding device.

v3
   - modify vhost to replace slave with client
   - modify memif to replace slave with client
   - fix variable names s2m becomes i2w etc.

[dpdk-dev] [PATCH v3 01/27] eal: rename terms used for DPDK lcores

[Stephen Hemminger]

Replace the old use of master/slave lcore with more inclusive
name of initial/secondary lcore.  The old visible API will
stay for now.

Change master2slave to new init2worker and vice-versa.

This patch breaks the expected practice for new API's.
The new rte_get_initial_lcore() will not go through the standard
experimental API phase; there is no functional difference
from the previous name.

[dpdk-dev] [PATCH v3 07/27] examples/bond: replace references to master lcore

[Stephen Hemminger]

Change the references to master lcore.
For now, leave refernces to slave for bonding since
that is part of the API not addressed yet.

[dpdk-dev] [PATCH v3 25/27] eal: mark old naming as deprecated

[Stephen Hemminger]

Use of old RTE_LCORE_FOREACH_SLAVE and rte_get_master_lcore_id()
are marked as deprecated.

All uses of these in DPDK itself is gone. This will cause warnings
for applications still using them.

[dpdk-dev] [PATCH v3 26/27] memif: replace master/slave with server/client

[Stephen Hemminger]

The names master and slave should be changed in this driver.
It is really a traditional client server model, so use those names.

[dpdk-dev] [PATCH v4 00/27] Replace references to master and slave

[Stephen Hemminger]

This set of patches changes the API and conventions around referring
to DPDK lcores. The first patch changes rte_get_master_lcore_id
and related calls. The rest fix the DPDK to use the new naming.

Buried in the documentation set are a couple of patches where
we were using incorrect naming around primary/secondary process.

This will could/should be flagged as an API policy violation
since new API is jumping the queue of EXPERIMENTAL. But we can
vote on the exception.

The one area left to be fixed is the bonding device.

v4
   - fix checkpatch warnings
     note: this patchset will cause some false positives
v3
   - modify vhost to replace slave with client
   - modify memif to replace slave with client
   - fix variable names s2m becomes i2w etc.

[dpdk-dev] [PATCH v4 01/27] eal: rename terms used for DPDK lcores

[Stephen Hemminger]

Replace the old use of master/slave lcore with more inclusive
name of initial/secondary lcore.  The old visible API will
stay for now.

Change master2slave to new init2worker and vice-versa.

This patch breaks the expected practice for new API's.
The new rte_get_initial_lcore() will not go through the standard
experimental API phase; there is no functional difference
from the previous name.

It's more difficult than it needs to be to review this patchset as it's 
out of date with current code.

This is probably a rebase error, looks like it belongs with the memif patch.

Isn't it "rte_get_initial_lcore"?

Also, as i've already mentioned in the response to the cover letter, i 
think "main lcore" would be more descriptive than "initial lcore".

Comments in pci_common_uio.c:54 and vmbus_common_uio.c:88 refers to 
secondary process as "slave", should probably fix that too.

You mentioned "bonding" driver as needing work but there's actually a 
whole bunch of instances of such terminology being used internally in 
other drivers as well (e.g. cryptodev scheduler). A quick grep on 
"master|slave" gives us a huge list of files, and while some of them are 
spec terms (e.g. PCI bus mastering), a lot of them aren't. I'm of course 
not suggesting it all should be done in this patch, just noting that 
bonding isn't the only driver needing work :)

As for contents of this patch (provided the corrections mentioned above 
are done),

[dpdk-dev] [PATCH v4 07/27] examples/bond: replace references to master lcore

[Stephen Hemminger]

Change the references to master lcore.
For now, ok to keep 'slave' for bonding since
that is part of the API not addressed yet.

[dpdk-dev] [PATCH v4 25/27] eal: mark old naming as deprecated

[Stephen Hemminger]

Use of old RTE_LCORE_FOREACH_SLAVE and rte_get_master_lcore_id()
are marked as deprecated.

All uses of these in DPDK itself is gone. This will cause warnings
for applications still using them.

Presumably this is a generic header, should we introduce GCC-specific 
things there?

It works with Clang as well. Likely ICC but don't have that.

_Pragma is C99 standard so MSVC know it.
MSVC should ignore any pragman it doesn't understand.

There is a better pragma for deprecating keywords in MSVC, but GCC and Clang don't
understand it.

Deprecating macros sounds like something we might want to do in the 
future, can't we put some macro into rte_common.h to address this? e.g. 
something like

#ifdef MSVC
#define rte_deprecated_macro _msvc_pragma_whatever()
#else
#define rte_deprecated_macro _Pragma("GCC warning ...")
#endif

and use this macro here?

FYI, DPDK on Windows is compiled with Clang, only linker is from MSVC. And
MinGW uses GCC toolchain. Why care about MSVC here?

Ah, OK. I'm not too familiar with Windows port, i was assuming it uses MSVC.

I don't have a strong opinion on this, but IMO it's certainly better 
than having a compiler-specific things in an API header file :)

Oh, sure, apologies for not picking up on that :D

A bit on the ugly side, but should work:

#define __rte_deprecated_macro(val) (_Pragma("GCC warning \"'" #val "'\" 
is deprecated\"") (val))

To be used as:

#define NEW __rte_deprecated_macro(OLD)

(I feel there could be confusion between __rte_deprecated and 
RTE_DEPRECATED, so both for consistency and clarity, i believe 
"__rte_deprecated_macro" would be a better name - however, no strong 
opinion, RTE_DEPRECATED is fine by me as well)

Sorry, realized that i've done it the other way around :D

Perhaps this one would be better:

#define __rte_deprecated_macro(old) _Pragma("GCC warning \"'" #old "'\" 
is deprecated\"")

...

#define OLD __rte_deprecated_macro(OLD) NEW

The compiler issues a warning when it finds a pragma that it doesn't recognize, and continues compilation.

[dpdk-dev] [PATCH v4 26/27] memif: replace master/slave with server/client

[Stephen Hemminger]

The names master and slave have no place inside this driver.
It is really a traditional client server model, so use those names.

Isn't this an externally visible change? Or do we not provide any 
guarantees for PMD devargs working across releases?

In any case, i think a release notes mention of this would be nice to have.

Otherwise, i took a quick look, LGTM

It does change devargs. Let me go back and put in release note, and add
compatibility (nag) layer.

[dpdk-dev] [PATCH v4 27/27] vhost: rename SLAVE to CLIENT

[Stephen Hemminger]

The vhost is a client server architecture so replace the
term slave with client.

Re: [dpdk-dev] [PATCH v4 27/27] vhost: rename SLAVE to CLIENT

[Xia, Chenbo]

Hi Stephen,

Thanks for working on this! The slave/master naming of vhost is defined
by vhost-user spec, which is maintained by QEMU. I think if we want to 
change it. The spec in QEMU should first be changed, then as an implementation
of the spec, we could easily change it. Also, using server/client to be the
new version may cause some code confusion in vhost. Because vhost
traditionally can act as a socket server or client (you can see the names in the code)
and the vhost-user slave/master generally refers to vhost-user pmd/QEMU.
So it may make the code hard to understand. Do you think this make sense?

Thanks!
Chenbo

LOL all these patches trip the new checkpatch check for master

This set annonuces the upcoming changes for 20.11 around master/slave
and blacklist/whitelist. It also fixes several places in the
current code where the wrong and confusing terminolgy was used.

Since 20.11 is going to be ABI incompatible with previous versions anyway,
can we not have the function as a macro alias for the new, allowing us to
remove the old sooner without breaking any apps? Even if this is not the
case, I think it might be better to change "21.11 version" to "a future
release" to allow us some flexibility on when to remove them in case we can
remove them sooner.

It doesn't say that the old argument will be kept for compatibility in 20.11.

Testpmd is not part of API/ABI compatibility area so it is not a hard
requirement.

Not really hard, but I would say it is annoying enough to consider
maintaining compatibility in testpmd for some time.

Since these are macros and therefore not part of the ABI I think we can
remove them sooner than 21.11. Therefore similar to the previous patch can
we just use "future" relase rather than 21.11

If these are internal, we don't need to wrap them in 21.11.

current code where the wrong and confusing terminolgy was used.

v3 - review feedback and acks
v2 - fix wording and checkpatch about whitespace
