Atheros HAL problem

free_daemon

Hi,

I am new in FreeBSD. Currently I use Linux, but I wish to switch to FreeBSD. My Atheros PCMCIA-Card works under Linux with ath5k, but FreeBSD could not load the HAL for this adapter.

Linux output of "tail -f /var/log/messages" when i plug in the adapter
Code:

I know that the chip is not listed in ath(4) but i hope there is a possibility to get the card working, because it works under Linux.

Thanks for any help!

HAL status 13 means that the MAC/PHY revision isn't supported.

There's definitely a debug sysctl for ath_hal available with which you get MAC/PHY version, using that information someone might be able to hack something together.

I don't know exactly what you mean.

sysctl -a -o | grep debug, doesn't give me some debug output for ath...
 
see if you have these.
Code: 
hw.ath.hal.dma_brt: 2
hw.ath.hal.sw_brt: 10
hw.ath.hal.swba_backoff: 0
hw.ath.dwell: 200
hw.ath.calibrate: 30
hw.ath.outdoor: 1
hw.ath.countrycode: 0
hw.ath.regdomain: 0
hw.ath.debug: 0
hw.ath.dump:
 
sysctl -a -o | grep hw.ath
Code: 
hw.ath.bstuck: 4
hw.ath.txbuf: 200
hw.ath.rxbuf: 40
hw.ath.resetcal: 1200
hw.ath.shortcal: 100
hw.ath.longcal: 30
hw.ath.hal.swba_backoff: 0
hw.ath.hal.sw_brt: 10
hw.ath.hal.dma_brt: 2

It doesn't looks like that there is a debugging potability with sysctl.
 
There is, I could imagine that is not available because the driver could not attach to any hardware.

Btw, is there any way to set # sysctl hw.ath.debug=0xffffffff as an initial value for that sysctl? Through /boot/kernel/device.hints or something?

# sysctl hw.ath.debug=0xffffffff
Code: 
sysctl: unknown oid 'hw.ath.debug'

Sorry, I cannot find any parameters in device.hints(5) for enabling debugging via /boot/device.hints.

/etc/sysctl.conf?
 
I'm not sure as in I didn't test this, but it might be as easy as adding
Code: 
hw.ath.debug=0xffffffff
to /boot/loader.conf.
 
Okay, I the problem of setting up the debugging mod was that ath isn't build with debugging support. I changed to /usr/src/sys/dev/ath/ and add the following line to ah_osdep.h.
Code: 
#define  AH_DEBUG
Now its possible activate ath_hal debugging by:
Code: 
sysctl hw.ath.hal.debug=0xffffffff
If I plug in the PCMCIA card I get the following output:
Code: 
kernel: cardbus0: Expecting link target, got 0x0
kernel: cardbus0: Expecting link target, got 0x0
kernel: ath0: <Atheros 5212> mem 0xbf6b0000-0xbf6bffff irq 16 at device 0.0 on cardbus0

kernel: ar5212SetPowerMode: AWAKE -> FULL-SLEEP (set chip )

It looks like, that the driver could not get the correct MAC Chip Revision.
