[PATCH v8 00/23] IB/Verbs: IB Management Helpers

[Michael Wang]

Since v7:
  * Thanks to Doug, Ira, Devesh for the testing :-)
  * Thanks for the comments from or, Doug, Ira, Jason :-)
    Please remind me if anything missed :-P
  * Use rdma_cap_XX() instead of cap_XX() for readability
  * Remove CC list in git log for maintainability
  * Use bool as return value
  * Updated github repository to v8

There are plenty of lengthy code to check the transport type of IB device,
or the link layer type of it's port, but actually we are just speculating
whether a particular management/feature is supported by the device/port.

Thus instead of inferring, we should have our own mechanism for IB management
capability/protocol/feature checking, several proposals below.

This patch set will introduce query_protocol() to check management requirement
instead of inferring from transport and link layer respectively, along with
the new enum on protocol type.

Mapping List:
		node-type	link-layer	transport	protocol
nes		RNIC		ETH		IWARP		IWARP
amso1100	RNIC		ETH		IWARP		IWARP
cxgb3   	RNIC		ETH		IWARP		IWARP
cxgb4   	RNIC		ETH		IWARP		IWARP
usnic   	USNIC_UDP	ETH		USNIC_UDP	USNIC_UDP
ocrdma  	IB_CA		ETH		IB		IBOE
mlx4    	IB_CA		IB/ETH		IB		IB/IBOE
mlx5    	IB_CA		IB		IB		IB
ehca    	IB_CA		IB		IB		IB
ipath   	IB_CA		IB		IB		IB
mthca   	IB_CA		IB		IB		IB
qib     	IB_CA		IB		IB		IB

For example:
	if (transport == IB) && (link-layer == ETH)
will now become:
	if (query_protocol() == IBOE)

Thus we will be able to get rid of the respective transport and link-layer
checking, and it will help us to add new protocol/Technology (like OPA) more
easier, also with the introduced management helpers, IB management logical
will be more clear and easier for extending.

Highlights:
    The long CC list in each patches was complained consider about the
    maintainability, it was suggested folks to provide their reviewed-by or
    Acked-by instead, so for those who used to be on the CC list, please
    provide your signature voluntarily :-)

    The 'mgmt-helpers' branch of 'git-9UaJU3cA/F/QT0dZR+AlfA@public.gmane.org:ywang-pb/infiniband-wy.git'
    contain this series based on the latest 'infiniband/for-next'

    Patch 1#~14# included all the logical reform, 15#~23# introduced the
    management helpers.

    Doug suggested the bitmask mechanism:
	https://www.mail-archive.com/linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg23765.html
    which could be the plan for future reforming, we prefer that to be another
    series which focus on semantic and performance.

    This patch-set is somewhat 'bloated' now and it may be a good timing for
    staging, I'd like to suggest we focus on improving existed helpers and push
    all the further reforms into next series ;-)

[PATCH v8 02/23] IB/Verbs: Implement raw management helpers

[Michael Wang]

Add raw helpers:
        rdma_protocol_ib
        rdma_protocol_iboe
        rdma_protocol_iwarp
        rdma_ib_or_iboe (transition, clean up later)
To help us detect which technology the port supported.

[PATCH v8 10/23] IB/Verbs: Reform cm related part in IB-core cma/ucm

[Michael Wang]

Use raw management helpers to reform cm related part in IB-core cma/ucm.

Few checks focus on the device cm type rather than the port capability,
directly pass port 1 works currently, but can't support mixing cm type
device in future.

Didn't you see that patches 15~23 will be squashed into one?


Also, when you post version N you need not only to list the changes 
since version N-1 but rather also to keep the full changes since Vx for 
x=1...N-2, reviewers needs not chase your previous cover letters and see 
if/whatwent wrong, specifically with a sensitive series like this one.

So if/when there's V9, use that practice, and for the time being, reply 
on the V8 cover letter with the full listing of changes

Or.

I missed the conversation on that, you mentioned to remove the
CC list but don't want to merge the patches, correct?

That maybe too long and with some outdated info, I can reserve
the log since this version if it was preferred by folks.

I'm using git send-mail which reply on the cover of each version,
not sure how to reply on a prev cover? and that won't start a new
thread for the new version, isn't it?

Re: [PATCH v8 00/23] IB/Verbs: IB Management Helpers

[ira.weiny]

I have run with this series and the only issue I have found is not with this
patch set directly.

This patch:

>   IB/Verbs: Use management helper rdma_cap_ib_mad()

causes an error when you actually use the port passed from the ib_umad module.
I have a patch to fix that which I found while trying to build on this series
for the use of a bit mask.

Doug, I don't know what you would like to do for this fix.  I am submitting it
shortly with a new version of the core capability bit patches.  If you want to
just add it after this series or force Michael to respin with the fix?  Frankly
I vote for the former because as it stands this series does not break directly.
It was only after I changed the implementation of rdma_cap_ib_mad that it
broke.


For the rest of the series.

Re: [PATCH v8 00/23] IB/Verbs: IB Management Helpers

[ira.weiny]

I have run with this series and the only issue I have found is not with this
patch set directly.

This patch:

>   IB/Verbs: Use management helper rdma_cap_ib_mad()

causes an error when you actually use the port passed from the ib_umad module.
I have a patch to fix that which I found while trying to build on this series
for the use of a bit mask.

Doug, I don't know what you would like to do for this fix.  I am submitting it
shortly with a new version of the core capability bit patches.  If you want to
just add it after this series or force Michael to respin with the fix?  Frankly
I vote for the former because as it stands this series does not break directly.
It was only after I changed the implementation of rdma_cap_ib_mad that it
broke.


For the rest of the series.

As I recall, there was a comment from Or requesting to squash some of
the individual patches down, but I no longer have that email in my Inbox
to double check.  And it seemed like there was one other review comment
not yet addressed.  Do I have that right Michael?  And if so, are you
working on a v9?

As I recall, there was a comment from Or requesting to squash some of
the individual patches down, but I no longer have that email in my Inbox
to double check.  And it seemed like there was one other review comment
not yet addressed.  Do I have that right Michael?  And if so, are you
working on a v9?

AFAIK Or was asking to merge the #15~23, and want to reserve the changelog
meanwhile reply the cover of prev version (I'm still confused on that...),
I've replied but get no respond yet.

I can make a v9 to merge the #15~#23 if that could benefit the maintainability,
please let me know your opinion :-)

About the Bug, if it was not introduced in this series, maybe including the
fix in next series would be better?

Michael Wang

AFAIK Or was asking to merge the #15~23, and want to reserve the changelog
meanwhile reply the cover of prev version (I'm still confused on that...),
I've replied but get no respond yet.

I can make a v9 to merge the #15~#23 if that could benefit the maintainability,
please let me know your opinion :-)

About the Bug, if it was not introduced in this series, maybe including the
fix in next series would be better?

I don't think it would make a significant difference.  I've pulled the
v8 patchset out of patchworks and I'll throw a new branch with it
included up to my github repo sometime today.
