[ath9k-devel] LEDs

[Mihai Moldovan]

Hi all,

quick question, is there any way to enable the LED on an ath9k supported
card?

I tried loading ath9k with blink=1 but it doesn't light anything.

Besides, the driver emits those messages:

[   15.118448] Registered led device: ath9k-phy1::radio
[   15.118471] Registered led device: ath9k-phy1::assoc
[   15.118498] Registered led device: ath9k-phy1::tx

I'm not entirely sure what those led devices are supposed to be, as both
cards have one LED only (probably radio on?)

Best regards,


Mihai

please tell us which card you are using. does the LED is not even getting ON

sudo modprobe ath9k blink=1 will enable LED blinking on tx traffic

are you using latest wireless-testing or compat wireless , current
ath9k LED makes use led control support via mac80211

AR9380 (AR9300) mounted in an mPCIe to PCIe adapter (not sure those will
actually handle all device's LEDs) and some AR5008 card.

Nope, never did.

Yeah I know, but I thought I might give it a try. :)

Nope, in-kernel drivers in 2.6.38.6. I used to use compat-wireless, but
it broke once in a while. May give it a try though.
On the other hand, that's not really an issue and I hestitate to change
a running system, I'm just wondering why the LEDs did never work. :)

Best regards,


Mihai

commit 353e5019e048562dc8f434c6237d41ef5e758922
Author: Senthil Balasubramanian <senthilkumar@atheros.com>

    ath9k: Fix LED gpio for AR93xx chipsets.

    The LED gpio is incorrectly programmed for AR9300 and so the led
    is not working propelry. AR93xx uses gpio 10 for LED and not the
    default.

Aaah indeed, it's included in 3.0 too, and I want to give it a try.
Let's see whether it works. :S

Otherwise, I'll try compat-wireless (and I'll even upgrade if 3.0 works.)

Thanks so far. :)

Best regards,


Mihai
