Hi Rafał,
If you are refering to this line
>>> + } while ((e = brcmf_deq_event(cfg_priv)));
The extra parentheses are added to fix a compiler warning:
drivers/staging/brcm80211/brcmfmac/wl_cfg80211.c: In function
‘brcmf_event_handler’:
drivers/staging/brcm80211/brcmfmac/wl_cfg80211.c:3576: warning: suggest
parentheses around assignment used as truth value
Thanks

Does checkpatch allow that assignment in the while statement? I would expect it
to want you to
e = brcmf_deq_event(cfg_priv);
} while (e);

Yep. That is the v2 I sent. btw checkpatch did not complain on the
original patch.

In wl_cfg80211.c two semaphores were used to trigger a task to process
an event. The wait queues are better suited for that purpose. This also
removes checkpatch warning on sema_init() calls in this source file.

I should have compiled it before sending v2. Please drop this one and
stick with the original patch.

It doesn't really matter either way, but I prefer the original one.
Checkpatch.pl only cares about if statements. This is fairly
idiomatic C. After all we wouldn't write a while statement like:
foo = some_func();
while (foo) {
frob();
frob();
foo = some_func();
}
We'd just write:
while ((foo = some_func())) {
frob();
frob();
}
And do while() feels the same to me.

Iovar IOV_BLOCKSIZE code is not actually setting the sdio
function's block size. Use cur_blksize provided by mmc core where
necessary.

You are forcing IOV_MSGLEVEL to 1, so I expected values of IOV_* are
really important in some piece of code. Now you change them. AFAIU it
means you break something, or you can drop " = 1".

IOCTL codes do have a strong ordering as user-space application and
driver need to have the same code for the same entity. IOVs are internal
numbers for the driver only so there is no issue in renumbering those.

Then you can note dropping " = 1" to avoid confusion for
new-code-readers :) For your TODO.

I believe this driver is meant to support BCM4329, which is not PCI(e)
board. What adapter do you use?
I've heard about Arasan adapter. Have you tried it? Is that something
reachable from arasan.com?

Is there also a softmac version of the BCM4329 available? The wl driver
shipped with the vendor firmware of my BCM4716 device detects one of the
wifi chips as BCM4329. I think it is the one in the BCM4716 and that is
already supported by b43. Or is this a wrong information?
Here is the output of the kernel log:
eth0: Broadcom BCM47XX 10/100/1000 Mbps Ethernet Controller 5.10.144.3
eth1: Broadcom BCM4329 802.11 Wireless Controller 5.10.144.5
PCI: Enabling device 01:01.0 (0000 -> 0002)
eth2: Broadcom BCMa8d8 802.11 Wireless Controller 5.10.144.5

Please, try lspci and if you can, b43. I believe that is 14e4:4329
which is BCM4321.
Why wl can't properly print chipset name - ask Broadcom.

Our brcm80211 source tree under drivers/staging contain two drivers. The
brcmsmac driver currently supporting the PCI(e) cards with bcm43224,
bcm43225, and bcm4313 chips and the brcmfmac driver currently supporting
the SDIO card with bcm4329 chip. brcmsmac is a mac80211 driver and
brcmfmac is a cfg80211 driver.
We indeed use the Arasan adapter and both drivers are running in nightly
test cycle testing our common internal repository. So the drivers are
functionally tested on the x86 platforms (32 and 64 bit). Also looking
at sparc64 and powerpc64 but not in a nightly cycle.

Is there a chance you can donate me with such a adapter and card?

Hi Rafał,
If your interest is getting SDIO supported in bcma this card is not very
useful to you. The bcm4329 is using the SSB interconnect.

That surprised me, interesting. I've never dig into brcmfmac code.
This still should be possible to adopt brcmfmac to use ssb, right? A
first random ssb-related function: dhdsdio_chip_resetcore. It
duplicates ssb code.
I'm still willing to help in brcmfmac development.

Sorry, I meant to respond to this earlier. The Arasan adapters are in very
short supply here, and honestly they have enough issues that we're looking for
better options. A possibly better approach would be a device with a BCM4329 on
the motherboard (e.g. table, phone, etc) that can run a relatively stock linux
kernel. However, I don't know of a specific platform at the moment to
recommend.
A second choice would be something with a decent sdio controller built-in.
Some older laptops worked ok (e.g. Dell E4100), but they're more and more
diffucult to find.

Nexus One phone?

That's a possibility. Are people running recent, relatively unmodified linux
kernels on the Nexus One? (Or you could backport brcmfmac to the Android
version of the kernel, perhaps using compat-wireless).

folks run debian from the sdcard [1], a mainline kernel shouldn't be too
big of a stretch from there. Especially if the purpose is for testing
wifi. Don't need PM, GSM, display, 3D, etc for that.
Note, I haven't tried it yet, myself. It's been on the _long_ list of
projects. It would be higher on the list if brcmfmac supported all the
normal Linux features like monitor mode, AP mode, multiple-VAPs, etc.
Or, at least, was in mainline and would accept patches adding such
features... ;-)
hth,
Jason.

Would definitely accept patches for such features! We're definitely interested
in them, and they're all on our list to add, but crossing the chasm is the
first step.
