Question: ath6kl (driver/net/wireless/ath/ath6kl) with debug_mask value

Question: ath6kl (driver/net/wireless/ath/ath6kl) with debug_mask value

[Sangwook Lee]

Hi

I am running ath6kl-cleanup git.
If I add debug_mask values with ath6kl.ko as like followings, I get
the success full results,
but without this, "iwlist wlan0 scan" fails.

ath6kl: hw 2.0 fw 3.1.1.149

1) SCAN success with debug values: ( 0xc44,c40,40)
$ insmod ath.ko
$ insmod ath6kl.ko debug_mask=0x40
$ ifconfig wlan0 up
$ iwlist wlan0 scan

2) SCAN failure
$ insmod ath.ko
$ insmod ath6kl.ko
$ ifconfig wlan0 up
$ iwlist wlan0 scan
With this case, there is no coming event "WMI_SCAN_COMPLETE_EVENTID".
After receiving  "ath6kl: WMI_EXTENSION_EVENTID"
iwlist shows error message:
      wlan0     Failed to read scan data : Resource temporarily unavailable


Thanks

BTW, ath6kl-cleanup.git is not updated anymore. Instead there's now
ath6kl.git which follows wireless-testing. You can find it from
git.kernel.org (when it's up again) or from github.

Hmm, I'm not sure if I have hw 2.0. I try to find one from my "stash" :)

0x40 is ATH6KL_DBG_HTC_RECV. I guess the debug prints slow down the
execution and papers over the bug. At least I can't think of any other
explonation right now.

Before I'm able to find a hw 2.0 device, can you try to debug this more?
When scanning fails can check if ath6kldev_intr_bh_handler() is called
or not? When scanning fails it usually happens because irqs are failing.

Can you share any details about your setup? From linaro.org I assume you
are using an arm board of some sort ;)

Thanks for this info, I will use new git.

OK, let me debug this point later.

Hi Kalle

I used  git://github.com/kvalo/ath6kl.git for-linville (Sat Oct 1
09:43:09 2011 +0300)
to run AR6003 HW2.0 (hw 2.0 fw 3.1.1.149) in my ARM board.

But I faced booting problem as like the following:
Is there any changes for AR6003 HW2.0 with the latest ath6kl git ?

We don't actively test hw 2.0 anymore, actually I'm not even sure
anymore if I have hw2.0 anywhere. If I find the time and a hw2.0 card,
I'll try to debug this.
