[PATCH 06/20] staging: brcm80211: remove unconditional code blocks from brcmfmac

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

Using a block statement to scope function variables is not
common in linux kernel development. Browsed through the brcmfmac
to remove those.

[PATCH 13/20] staging: brcm80211: removed two fullmac sparse spinlock warnings

[Franky Lin]

From: Roland Vossen <rvossen@broadcom.com>

By deleting three redundant functions. The spinlock was related to
event queue operation. Event queue data members were also renamed
to make their function more clear.

[PATCH 16/20] staging: brcm80211: removed log after kzalloc()/kmalloc() failure

[Franky Lin]

From: Roland Vossen <rvossen@broadcom.com>

[PATCH 18/20] staging: brcm80211: consistent naming of struct net_device *ndev

[Franky Lin]

From: Roland Vossen <rvossen@broadcom.com>

Code cleanup. Various names (ndev, net, dev) were used for the
same structure. Settled for 'ndev'.

Just about all of this patch is not good.

Splitting format strings is poor style, makes
error messages difficult to find via grep and
is error prone.

You should update your checkpatch version.
Current checkpatch doesn't warn about this.

It'd be better if you could find some way
to reduce the 6 tab indentation rather than
split 20 char format strings into pieces.

Indeed we have too many levels of indentations in some functions of 
fullmac. Will clean that up.

Greg, could you please drop this one? We will take care of the

Ok, this is the 7th patch series since the last round of "how do we get
our driver into mainline" happened.

And while code is great and nice, I still haven't seen any real answers
to all of the questions that were asked of the Broadcom driver team
during that review by the linux-wireless developers about how things
will be handled properly due to the overlap in functionality with the
existing "real" driver in the tree.

So, can you please start answering these questions?  I'm loath to keep
accepting patches until that all gets straightened out as it potentially
wastes my, and your, time by doing so.

In other words, I'm not going to apply any more patches until this gets
resolved.  Consider this patchset dropped from my to-apply queue for now
because of that.

thanks,

Let's qualify this to "some developers".

One thing I'd like to point out is that the Broadcom's firmware API has
always undergone changes over time. I'm actually surprised that b43
works as well as it does (which, tbh, isn't very well at all, at least
for me with some 11n PHY). I also don't think that Broadcom are going to
maintain compatibility and/or maintain new firmware features for old
devices, that just doesn't make any sense.

As a consequence, I don't think there's any sense in saying b43 should
be the driver that Broadcom must support upstream. Even we, back then,
split b43 into b43 and b43legacy when it wasn't really possible any more
to test and maintain a single driver for different devices. Rafal has
shown that it is possible today (to some extent) to do that for the
newer chips and the older 11g only chips that b43 still supports, but
I'm not convinced that with new features like P2P this will be true in
the future.

And this is just discussing the technical side -- the support side is an
entirely different question.

Now, don't get me wrong -- I don't think the duplication is a good
thing. A lot of the PHY code could be shared. However, I think it will
probably not be possible for much longer to share the higher level MAC
code that programs the SHM etc.

So I don't claim to know what the solution is, but I think simply
rejecting the Broadcom effort like most people seem to imply is a good
solution at all. It will leave all of us in a bad spot by creating a
driver that has to support too many different devices.

It would be nice to see some of this.  I don't think anything is
stopping either Broadcom _or_ the b43 team from posting such patches.

I'm inclined to agree.  Despite recent heroic efforts, b43 remains
behind in it's support for current features of Broadcom hardware.
As developers find other gainful interests, that gap is sure to widen
-- it certainly was quite wide just a few months ago.

As Johannes implies, it seems likely that newer Broadcom hardware will
need to be supported by a different/new driver anyway.  Is there
some reason why that new driver needs to have a b43 pedigree?
If we want/expect Broadcom to support that new driver, is it so
unreasonable to allow them to start from the codebase they prefer?
I don't think it is.

Broadcom has come a long way in the wireless arena.  I think we would
be better served by bringing them into the fold than by continuing
to demand what they don't feel able to provide.

And brcmsmac stays behind b43 if you count feature different than
performance. Monitor, RFKILL, Ad-hoc, AP, hw crypt, supported PHYs,
etc.

And what if Broadcom decides to abound their brcm80211 project?

I vote for working together, I can not see a better solution.

We still don't have any clue, when is that going to happen.

It's hard to talk about API compatibility breakage, until it really
happens. So far we support all firmwares, I don't have much more to
say about that. We can decide about some driver splitting, when API
breakage really happens. Now I think that are just thoeritical talks.

That's what we try to discuss with Broadcom. If they really see a
requirement to split driver into 2, they have to explain that and
discuss it with us.

I'm flexible, I've accepted Michaels' view on SSB & BCMA. We just need
to make Broadcom talk with us.

Having Broadcom ignoring all out questions and just sending more&more
patches is not good as well. How differently we can make them talk?
I've requested for discussion several times.

Actually, when we got some single response from Broadcom about their
relation to b43, they haven't mentioned support for old HW is any
problem at all. They just pointed we don't support calibration for
N-PHY and we don't support 802.11n feature for a better performance.

I feel we're creating some problems ourself. Just some guessing that
support for older HW can be real problem for future development... not
confirmed by anyone at all.

If you look at it from the perspective of a hardware manufacturer,
supporting EOLed chips is generally not a good return on investment.
There is no new revenue associated with them so any work that goes
into them stands to return very little.

That's another thing to discuss with Broadcom.

In open source kernel world, we hopefully won't let anyone drop
support for older hardware, just because it's not produced anymore.
Probably something like forking driver or modularizing it makes more
sense to us.

On the other hand we don't want Broadcom to support b43 and all the
PHYs it covers. We've already mentioned they could decide to support
b43 but limit their official support to selected cards only. They
(again) didn't response how they see such an idea.

What we really need is some communication with Broadcom and I guess
that's what Greg mostly wanted to achieve.

Support is one thing, the other is to enable the community. The later
can be done while real support goes into the newer chipsets.

AFAIK it does (unless you mean hardware covered by b43legacy).

If you take a look at 666.2 firmware, it's still available for core 5

The reason I've added support for new firmware without dropping
support for older, was users experience. I didn't want to leave anyone
with b43 not working after kernel update (without firmware update).

That is the correct thing to do. As I see it, this firmware change is a lot less 
intrusive than the changes that led to the b43/b43legacy split, where keeping 
the old version working took a lot of bookkeeping.

Perhaps in 2 or 3 years, we might want to deprecate the older firmware and force 
users to go to the newest style, but there is no rush.

I think most of the outstanding series from Broadcom are
(almost?) exclusively for their fullmac driver, which has not overlap
with b43.  We should be moving forward toward getting the fullmac
driver into wireless-next.

Ok, that's great, but again, no one from Broadcom has said what their
plans are, only sent lots of patches, which while wonderful, has caused
some confusion on my and other parts.

Our original plan was to remain a separate driver from b43. We were aware of it and all the good work that had been done to create it and we had no intention of interfering with it.  At that point there had not been very much recent movement in b43 and it did not support any of our AXI based chips.  We figured that ssb vs AXI was a good dividing line and there would be no conflict, and there wasn't initially.

Internally, prior to releasing to staging tree, development had gone quickly and it didn't take long at all to get the driver up and running.  We did not anticipate that things would go somewhat slower in the staging tree and a year (and hundreds of patches) later we are still there.  During that year b43 got some limited support for the same new chips brcmsmac already had, into its driver.  So now, here we are... both drivers supporting the new chips and b43 also supporting the old.  

We have seen the requests for us to add AXI based chipset support into b43.  I don't think that will happen in a substantial way:
- Our driver is already stable and performance is better than b43 in terms of AXI chips.  B43 seems quite raw: its full of TODO and FIXME notes and performance is 1/10th of brcmsmac on our testing. Spending another round of time and effort on b43 to get it to the place where smac already is, seems redundant and unattractive. 

- Much of brcmsmac code comes from our internal source which has whole organizations charged with testing it for compliance, compatibility, performance, etc. We understand that that is of no direct consequence but since brcmsmac code is a direct descendent of that code, much of that background still applies. Switching to b43 would mean throwing all that infrastructure and testing away and going with a driver that has none of that (that I know of).

- Most of the recent b43 additions support comes from a single person doing reverse engineering. brcmsmac has a few software people working on it directly and hundreds of people working on it indirectly (through the internal version) including engineers working on firmware, RTL, testing, etc.   

- B43 team has made the case several times that it has more features than brcmsmac.  A reminder: We were specifically asked NOT to add features while in staging tree and we have held back on features to honor that request.  AP, IBSS, 40 Mhz, using bcma, hw crypto and others, are all features we have been waiting to do.   We also have a backlog of several new chips we want to add.  And of course, we will would be adding future chips and features as they come out.

We invested a year trying to be good Linux citizens, laying out our initial plans, following the rules, working transparently, folding in feedback, submitting hundreds of patches in plain sight of everyone and now folks are asking about our plan.  Our plan is get the brcmsmac and brcmfmac into mainline and keep following that up with new features, new chips and continuing support.

Other than barely supporting one of our chips first in mainline, I would really like to understand what are the benefits and justifications of using b43 over brcmsmac for AXI based chips in the long run.  Can someone explain them?

We were aware of it and all the good work that had been done to create it and we had no intention of interfering with it.  At that point there had not been very much recent movement in b43 and it did not support any of our AXI based chips.  We figured that ssb vs AXI was a good dividing line and there would be no conflict, and there wasn't initially.

The first obvious problem is that there are SSB and BCMA (aka AXI)
cards using N-PHY. That resulted in PHY code duplication between b43
and brcmsmac. And since we already supported N-PHY in b43, adding bcma
support automatically gave us BCM43224 and BCM43225 support. That of
course means duplicated supported for the same hardware.

Well, I guess you were comparing brcmsmac working in 802.11n mode vs.
b43 workin in 802.11g mode? When I was comparing both drivers in
802.11g mode, they were similar in performance. Please see my tests at
http://zajec.net/ . If that's true, we can also say b43 is ∞ faster
than brcmsmac... if you compare AP or monitor mode.


> - Much of brcmsmac code comes from our internal source which has whole organizations charged with testing it for compliance, compatibility, performance, etc. We understand that that is of no direct consequence but since brcmsmac code is a direct descendent of that code, much of that background still applies. Switching to b43 would mean throwing all that infrastructure and testing away and going with a driver that has none of that (that I know of).

Yes, I'm aware you may be not so comfortable with differences between
internal driver and b43.
However you're already at the place, when you can not just copy&paste
code from your internal driver to brcmsmac. You have to adopt in
anyway. Are there really so many differences if you look at b43? DMA
is something you probably don't need to touch. PHY code should be
portable to b43 in the same way it is to brcmsmac. The biggest problem
is to touch some general things, not PHY-directly-related. And even in
that code we share a lot of code. Our code is based on RE of your
driver. It has to be similar.


> - Most of the recent b43 additions support comes from a single person doing reverse engineering. brcmsmac has a few software people working on it directly and hundreds of people working on it indirectly (through the internal version) including engineers working on firmware, RTL, testing, etc.

You're doing much harder job and obviously you need much more people.
I just implement the driver, without testing hardware for various
possible configurations, etc. That's the only explanation how we've
achieved such a good state. We copied init/config values from your
driver, didn't invent them ourself.


> - B43 team has made the case several times that it has more features than brcmsmac.  A reminder: We were specifically asked NOT to add features while in staging tree and we have held back on features to honor that request.  AP, IBSS, 40 Mhz, using bcma, hw crypto and others, are all features we have been waiting to do.   We also have a backlog of several new chips we want to add.  And of course, we will would be adding future chips and features as they come out.

Well, you spent a lot of time on cleaning brcmsmac, I spent a lot of
time on adding support for new hardware. I believe now we both are at
similar stage from reaching fully functional, feature-full driver. 1:1
for both of us ;)

Well, you were submitting patches, but you weren't discussing anything
with us. That's really important in being a good citizens.
How many times have I asked about the firmware? How many times about
access to the hardware? How many times about the future? Really, I was
trying hard to cooperate, you just were ignoring all of that :|
We've now finally made you respond to the questions about the future,
but you still ignore my fw questions and hw requests.
This of course resulted in the complex situation we have now.


> Other than barely supporting one of our chips first in mainline, I would really like to understand what are the benefits and justifications of using b43 over brcmsmac for AXI based chips in the long run.  Can someone explain them?

What I don't like about brcmsmac?
1) Not modularized, bcma support built in and duplicated with bcma module
2) Poor quality code
3) Duplication of a lot of code with bcma&b43. Not just PHY code, but
also more general functions, DMA support, MAC, etc.


I don't know what more I can propose now.

We can of course continue our work without differences. I'll add
support for more cards and make it stable, meanwhile you will finally
clean your driver. What then? We will have 2 driver supporting same
hardware with comparable quality. Having 2 mainline drivers for the
same hw is not really a good option. Will we keep brcmsmac in staging
just to receive new PHY support from you and keep copying it to b43?
Doesn't sound to optimistic. How else do you see the future?

I think that is a completely bogus question.
Whether b43 or brcmsmac is better does completely depend on the application.
And for that single reason I do not see either b43 or brcmsmac being dropped
in favor of the other one any time soon.

You guys obviously don't want to support legacy hardware. So there is absolutely
no way to drop b43 in favor of brcmsmac. That is _impossible_.
And I do agree that it would be completely insane for you guys to support the legacy
b43 802.11g code.

The other way around, dropping brcmsmac in favor of b43 would be insanely stupid, too.
It would basically be dropping broadcom-linux-wlan support. Nobody wants that.

I do, however, think that a separate broadcom-supported PHY module should be created,
that is used by both brcmsmac and b43.

Agree and we are not proposing that.

We did however initially propose (and implement) a dividing line of ssb chips for b43 and AXI based chips for brcmsmac but b43 team chose to ignore/reject that.  I haven't heard any counter-proposal from b43. We would love to hear one.

I'm not totally opposed to that idea but it does not solve the primary issue of conflicting b43 and brcmsmac modules.

Well, what about embedded, for instance?

I'm not convinced that this is an issue at all and I'm not convinced that it has to be resolved.
At least not now.

I was referring to smac. There isn't any controversy over fmac AFAIK.

I was question about embedded devices like routers I believe.

The brcmsmac driver has been tested on a MIPS platform by Jonas Gorski
although only in STA mode (on a bcm63xx). Not having AP mode has been
explained in other emails.

Also we fully intend to transition to BCMA but that would also be new
feature added. Having AP mode and BCMA would enable you guys for using
it in the embedded targets, right?

It never hurts to look ahead. Both drivers have their use in the linux
tree and we should align which driver is doing what. Apparently we should
have yelled really hard when b43 was adding bcma support, because then
it snatched the chipsets we support as well. You learn your lessons the
hard way in Linux land, or so it seems ;-)

And I should have notice you add code for N-PHY with your initial
brcm80211 commit ;) There's always something that you won't notice at
the correct time.

I was aware of supported chipsets (by their names), but I got no idea
that they (BCM43224 and BCM43225) are N-PHY based ones. I though that
that are some totally new PHYs (like SSLPN/HT/LCN/LCNXN/etc.).

This just happened to be a MIPS, but apart from that it was still a
mostly standard fare PCIe connected BCM4313, no nothing really
embedded. What Michael (and Hauke, and Rafal) is talking about are
BCM47xx SoC where AMBA/AXI is the System Bus, and there is no PCI(e)
at all (except maybe for connecting a /second/ wifi).

This was one of the main motivations of the bcma driver.

Regards,
Jonas

P.S: Which reminds me, do you plan to (not) support the integrated
wifi in the BCM6362? This one seems to be neither bcma nor ssb, but
it's definitely Broadcom ;) (Haven't gotten my hands yet on a device
though).

All good points. The most rational I've seen in all of this discussion
really.

I agree that would be nice. However, I don't think that it should be
required for brcmsmac to get into mainline, nor do I think that there
should be a big rearchitecture for this. In fact, brcmsmac has a PHY
abstraction layer that looks perfectly usable to me. b43 has one too,
but it's nowhere near as fleshed out for all corner cases afaict.

Really the more important issue is support though. Rafal by himself
cannot possibly provide the level of support we're hoping to see from
Broadcom who I expect will eventually ship this driver to their
customers and support it, just like they do now with the driver it is
derived from.

Overall, the way I see it this really is a no-brainer. I really don't
see why we're even discussing this so much.
brcmsmac should be accepted into mainline as soon as possible (and I
think all the recent patchsets go a long way). After that, the Broadcom
team can easily port it to bcma, I expect that would happen within a few
weeks. Adding features to it should be fairly simple too, and go much
faster than adding any features to b43. (*)


b43 is really my child too. I spent a very long time on the reverse
engineering. But let's let it "die" peacefully. It has no reason to be
competing with a Broadcom-supported driver that supports the same chips.

johannes


(*) Rafal: Also, get a grip. Your much touted "monitor mode" is probably
a 50-100 line patch to brcmsmac. You're making yourself look extremely
childish by talking about it all the time as if it was the best thing
since sliced bread.

I fully agree with all of that.

It is time to merge the stuff into mainline. There really is no other option.

We all put a lot of effort into b43, but that does not imply that we have
to beat the dead horse.

b43 has to become a second b43legacy. Which means it must go into maintenance-only mode.
Features should probably be removed, too. But that has to be done after
mainlining of brcmsmac.

Completely dropping either of b43 or brcmsmac is not an option. So, Rafal, you can still
continue to work on b43. There are _lots_ of bugs and issues to fix/improve.
If you need/want some older b43 devices, I can certainly donate some of mine to you. (I have
at least piece one of any flavor of supported 802.11g devices in stock).

bcma is not only used to support the bus on a pci based wireless cards
it now also contains support for SoCs like the BCM4718. There it
provides a common interface to the hardware for the wireless so that
there were no changes in b43 needed to get the wireless core running on
this SoC. It also provides some parts needed to get the SoC boot in
Linux and so on, some parts are related to the MIPS CPU and not related
to the wireless core, so it makes sense to put that into an own module.

It's not really about seeing interest in that. I just don't see
advantages for us from this.

If we assume we will have the same level support in both drivers soon,
then what are the differences? brcmsmac seems to be preferred only
because Broadcom guys like it.

bcma is not the issue, it had to be created anyway. We can not accept
one driver handling all the BCMA/AXI cores (80211, ethernet, whatever
else). And you, I believe brcmsmac has to switch to bcma.

Chips tweaks mostly lays in bus code, which is bcma in this case. As
for PHY code, you've not even cared to take a look at our phy_n.c! But
you're commenting that anyway.
BCM43224 and BCM43225 are nothing special, there are N-PHY rev 6.
We've code for revs 1-6 from the beginning. That's how we got support
for that cards "automaticly". I was here since "ever", we just got to
add BCMA/AXI support.

[irony, yes]
Monitor mode is nothing esoteric anymore. I've compared b43 with
brcmsmac. b43 is 100000000 times faster (compared to 0 b/s).

I've said what I don't like currently in brcmsmac. I've also said both
drivers should be equal in next few months. Nothing really more to
add, it's not about flamewar. Plus Michael commented this nicely.

You really got to ignore previous thread about going mainline.
That issue was already pointed to me, and I've already started sending
patches for that.

I didn't comment your patches. Maybe I've said sth about amount of
them, but it's your choice to spend your time on cleaning, cleaning,
cleaning, I'm find with that.

I don't remember you saying finally "Sorry, we won't be able to donate
you with that". Will re-check.
Still, you refused to share BCM4331 (which is already available on
market, and even hackish-supported by b43). Same for BCM43227 and
BCM43228. I didn't even care to ask for some SSLPN card (which is also
available on the market in some routers, can find proves).
Oh, and you still didn't care too much about our firmware requests.

Please, do this soon. When merge window for 3.2 will open, you'll
receive all recent bcma code. If there is anything missing in bcma you
need, *please report that* (or provide patches).
I believe this is part of cleaning, nothing like new features. You'll
simply drop a lot of duplicated code by switching to bcma.

Yup, there is my question and respond from Henry:

Unfortunately not a word about donating me such a hardware. Plus not a
word about the cost.

Take a look at "Request for free-distributable Broadcom's (G|LP)-PHY
firmware" thread. I've been requesting and pinging you guys several
times. The response we got was:

That's all. Not really helpful.

Because doing inside a driver is wrong.  bcma is a separate bus layer
and really must stay outside the driver.  It can very reasonably argued
that the same is true for the PHY support.

Given the arguments from Johannes and other I think the only reasonable
outcome here is to make sure the broadcom drivers share

 a) the bcma bus support (already done), and
 b) the phy layer

and just make them the driver for the newer MAC revisions.

(and stop those fight already, shh..)

I am not disputing that the bcma bus driver was a good move, but there are
numerous chip devices out there with an internal bus of some sore and not
having a separate bus driver.

Regarding PHY support compared to a system bus on a chip is comparing
apples with pears. However, as said earlier we are not opposed to the
idea.

A BCMA bus driver and PHY layer does not give a wireless driver. Am I
missing something?

I thought this was just an open and lively discussion ;-)
