This patch set introduces preliminary support for the Atheros' AR9130/AR9132
SoCs built-in WMAC device. Tested with compat-wireless-2009-01-12 and 2.6.27.10
kernel on the following devices:
* Atheros AP83-050 reference board (AR9132 SoC, AR9106 RF)
* TRENDnet TEW-632BRP router (AR9130 SoC, AR9102 RF)
* Mikrotik RB433 board (AR7161 SoC) + AR5416 based miniPCI card
Changes since v2:
* parentheses around RTC register's names has been removed
* rebased against master-2009-01-12 of wireless-testing
Changes since v1:
* enabling support of the AR9100 has been moved to the end of the series
* bus specific cleanup routine has been rewritten
* PCI code converted to use 'softc.irq' as well
* setup of 'hw->flags' and 'hw->wiphy->interface_modes' has been removed
from ath_ahb_probe()
* unregistering of the ath_ahb_diver has been fixed
Changes since RFC:
* bus specific DMA routines removed
* bus specific register access routines removed
* irq value is stored in softc
* rebased against master-2009-01-06 of wireless-testing
11 patches will follow as replies:
Gabor Juhos (11):
ath9k: convert to struct device
ath9k: convert to use bus-agnostic DMA routines
ath9k: introduce bus specific cache size routine

ath9k: remove (u16) casts from rtc register access
ath9k: fix ar5416Addac_9100 values
ath9k: fix null pointer dereference in ani monitor code
ath9k: enable support for AR9100

* [ath9k-devel] [PATCH v3 03/11] ath9k: introduce bus specific cache size routine

To: ath9k-devel
The PCI specific bus_read_cachesize routine won't work on the AHB bus,
we have to replace it with a suitable one later.

The PCI specific bus_read_cachesize routine won't work on the AHB bus,
we have to replace it with a suitable one later.

Now that we have converted all bus specific routines to replaceable, we
can move the PCI specific codes into a separate file.

* [ath9k-devel] [PATCH v3 07/11] ath9k: get EEPROM contents from platform data on AHB bus

To: ath9k-devel
On the AR913x SOCs we have to provide EEPROM contents via platform_data,
because accessing the flash via MMIO is not safe. Additionally different
boards may store the radio calibration data at different locations.

On the AR913x SOCs we have to provide EEPROM contents via platform_data,
because accessing the flash via MMIO is not safe. Additionally different
boards may store the radio calibration data at different locations.

Writing the register at offset 0x98c4 causes a deadlock on the AR913x
SoCs. Although i don't have detailed knowledge about these registers,
but if i change the register offset according to the 'ar5416Addac' table,
it works. Additionally there is no reference to the 0x98c4 elsewhere.

In 'ath9k_ani_reset' the 'ahp->ah_curani' will be initialized only
if 'DO_ANI(ah)' true. In 'ath9k_hw_ani_monitor' we are using
'ahp->ah_curani' unconditionally, and it will cause a NULL pointer
dereference on AR9100.

In 'ath9k_ani_reset' the 'ahp->ah_curani' will be initialized only
if 'DO_ANI(ah)' true. In 'ath9k_hw_ani_monitor' we are using
'ahp->ah_curani' unconditionally, and it will cause a NULL pointer
dereference on AR9100.

Hi,
Finally got back to testing the wireless kernel, distracted for a bit:)
make/make modules/install all work.
when I run mkinitrd I get the output below.
Not sure why the modules are not found?
Found a message to say that these messages may occur if the module is now
compiled in.
In a message from Linus re rc3 http://lkml.org/lkml/2009/1/28/277 there is
a note
Alexey Dobriyan (37):
fs/Kconfig: move reiserfs out
Now I do not understand exactly what that means, but my system with the
rc3 kernel will not boot.
My whole system runs fine on reiserfs with 2.6.27.7-9-default .
i.e. the 11N has been up for a month with no problems.
Are there changes I have to make in the config for reiserfs?
Running SUSE 11.1
Thanks,
Brian.

No that is my addition to make the kernel unique.
I have been using it for months, it works.
This parm
(-W) Local version - append to kernel release
under general setup in menuconfig.

Oh OK cool, do you have your modules all in place before calling mkinitrd under
/lib/modules/2.6.29-rc3-wl-W/kernel ?

Well spotted. The short answer is NO. I would estimate that over 50% od
the files are missing?
In the default kernel under the FS directory I have about 45 dirs
including reiser.
Under the new FS I have 8 and reiserfs is not one of them, so the boot was
never goiong to work.
So I see two options.
1) You know of a possible explanation as to why the make/make install did
not work.
I would be happy to understand why:)
2) I should do the compile again paying more attention to the logs etc.
I must admit this is the first time I have ever had a problem(must have
compiled a 100 times).
In fact it was so reliable I left it running while I had tea:)
To be clear. What I did was to go into my original wireless testing
directory and did a git pull from there.
I assumed this would bring the wireless testing directory up todate.
I then did the make clean, make menuconfig, etc.
Thanks,
Brian

It means that reiserfs parts of fs/Kconfig were moved to
fs/reiserfs/Kconfig.

No configuration changes should be needed.

Make sure that all the above code is compiled into the kernel.
Alternatively, make them all modules.
As for the problem, you need to capture the boot error. You'll get
better help in a group more relevant to that message. Maybe try a list
for OpenSUSE.

Thanks for that, my understanding of how things hang together is going up
all the time.

Great. Given the errors I thought I might have missed something.

As Luis pointed out they were not.
So I did a Make clean again then a make bzImage.
This time I watched the whole thing and the reiserfs and everything else
appeared to compile ok.
However, when I did a make modules, reiserfs and other modules were not
done.
So naturally the modules_install did not install them either.
Is there some configuration option I need to change?
Also I just did a git pull from the directory of my 11.0 system I am now
on 11.1.
Do I need to scrap what I have and download the whole wireless-testing
again?

Obviously given the above I was not even getting to first base.

Remove all lines containing "REISER" from .config and run "make" again.
No need to run "make bzImage" and "make modules" separately, "make"
implies both. You will be asked whether to enable reiserfs. Select "m"
for it to be a module. Likewise, compile other required options as
modules to be sure they are enabled.

No. It's a purely configuration problem.

That's because you chose not to boot that kernel. Unless you had a
fatal installation error, but you chose not to show output of "make
install", so I don't know.
Sorry for offtopic. It's the last time I reply to this thread.

I confirm that my AR5416 miniPCI is still working with this patch on top
of yesterdays wireless-testing (master-2009-01-12).
Unfortunately, patch named "ath9k: move PCI code into separate file"
doesn't apply to the today's wireless-testing and needs to be rebased.
Current checkpatch.pl gets confused by several patches because an
"#endif" in the unchanged part somehow causes the preprocessor stack to
underflow:
Can't use an undefined value as an ARRAY reference at
scripts/checkpatch.pl line 453.
This appears to be a bug in checkpatch.pl and should not be considered a
problem in the patches.

I have noticed it, but i'm not a Perl expert, so I have checked the patches
with checkpatch.pl from 2.6.28.

I've got a reply from checkpatch.pl maintainer. The fixed file is at
http://www.kernel.org/pub/linux/kernel/people/apw/checkpatch/checkpatch.pl-testing
It has no problems with the new patchset.
