ath5k: issues with AHB support on ubiquiti bullet 2 (AR2315)

Hey all,

I'm just letting you know that I have been having issues getting the the
AHB support with the ath5k driver working (from compat-wireless 2011-01-05).

I'm testing it on an ubiquiti bullet 2 device which internally is a
AR2315 WiSoC. I am using openwrt backfire with the mac80211 package
patched to use a later version of compat-wireless (ie one with AHB
support in ath5k). I had to modify some of the patches in openwrt so
they applied cleanly, but don't think any affected the ath5k (and would
cause the problem i have).

Basically the issue is this. When I try to load the module as is in the
source tree, the system hangs and module never loads (device restarts
itself).

I tried a bit of debugging (sorry about any newbie techniques here, im
new to kernel debugging) by just printing and returning errors after
every main function called. The problem seemed to be with the first time
it called ath5k_hw_reg_write, which from my tracing seemed to be in th
wisoc reset function in the following chain.

ath5k_hw_reg_write (ath5k.h)
ath5k_hw_wisoc_reset (reset.c)
ath5k_hw_nic_wakeup (reset.c)
ath5k_hw_init (attach.c)
ath5k_init_softc (base.c)
ath_ahb_probe (ahb.c)

I then tried out a few things in the vain attempt to get it to load the

No Luis, this problem came from some recent changes in PAPRD before that 
it was Ok.

Correct, it's definitely not for upstream. nl80211 now has testmode
interface which can be used for that, but as wl1251 hardware is so old
already I doubt anyone has any interest on.

I have now read and commented some of your patches, I will go through
the rest today. But 18 patches in a patchset is quite a lot. To make
it easier to review and manage the patches I would recommend to split
them to smaller and logical patchsets.

[PATCH] wl12xx: update PLT initialization for new firmware

In revision > 6.1.3.0.0 the firmware expects memory configuration command
as part of boot. This was missing if driver boots in PLT mode.
The patch adds the memory configuration command, which fixes PLT commands
tx continuous and rx statistics.

Ralink RT2501/RT2573 USB Wireless Adapter crashes kernel 2.6.37

Hi,

I reported this issue for two Linux distribution (Arch and Mandriva)
after upgrading to kernel 2.6.37 and is rather critical for users of
RT2573 Ralink USB Wireless adapters. This leads to complete system
crash, which is solved either by using a wired ethernet connection, or
by downgrading the kernel to 2.6.36 version. This happens in
particular when watching a streaming video (e.g. Youtube). I do not
see any entry in the log files. The sound goes to a loop, system is
completely blocked and only a hard reset will allow rebooting.

I feel this issue has been reported for other distributions too:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/673682
and this may be related:
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2011-January/002935.html

I tried to use the compat-wireless drivers (2011-01-30), which were
compiled correctly, but rt2x00 module loading segfaults when inserting
the USB adapter.

What can I do to help squashing this issue?

Many thanks in advance.
Eric

Agree. It may be considered a fix from a particular user-space application
perspective (ie. NetworkManager) but from standards perspective there is
no reason to do this.

I have no immediate idea about the cause of the crash, but
did you make sure you unloaded _all_ wireless modules
before plugging in the USB adapter after installing
compat-wireless?  "make unload" or a reboot should do the trick.

If it still crashes, can you check dmesg for the crash messages?

Hi Johannes,

This happend on reboot, yes. I rebooted without the adapter plugged
in, then I left udev load the modules upon plugging the USB adapter.
I'll send you the error message in a few hours when I am back home.
Note that when the system freezes (the original bug, with the modules
from kernel 2.6.37), I get no log messages whatsoever.

Thanks,
Eric
