I have configured my kernel to use ath9k debugfs:

The location of these debugfs files should be in
/sys/kernel/debug/ath9k according to:
http://wireless.kernel.org/en/users/Drivers/ath9k/debug#Debugfs_files_for_ath9k
However, when I load the modules and plug in an ath9k device, I do not
get any ath9k debugfs files:
root@parallels:/sys# find /sys -name ath9k
root@parallels:/sys# find /sys -name rx_chainmask
root@parallels:/sys# find /sys -name disable_ani
root@parallels:/sys#
I do get the ieee80211 debug, though:
# ls -l /sys/kernel/debug/ieee80211/
total 0
drwxr-xr-x 6 root root 0 Jun 11 12:30 phy0
Do I need to pass some parameter to the kernel module on load to get
the ath9k debugfs? Am I missing something else?
Thanks!

Hi George,
When you say 'plug in an ath9k device' I assume you mean you plug it in
before you boot? There aren't any ath9k devices that I know of that use
USB. I believe they're all handled by ath9k_htc.
Aside from that, you found the right spot
(/sys/kernel/debug/ieee80211/phyN) for it to live. What does dmesg say
when you plug in/boot with the device?
