[ath9k-devel] Atheros [168c 0034] can't enable wireless button LED.
Hi experts, I tested the latest kernel v3.5-rc3 ath9k for the Atheros [168c 0034], code name is Miami. I found no matter how I press the wifi button to enable/disable the wifi, it doesn't work to me. Even I found the rfkill status for this interface is not changing. -- Thank you. ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel

[ath9k-devel] [PATCH 00/10] Add support for WOW in ath9k
From: Mohammed Shafi Shajakhan moham...@qca.qualcomm.com Add support for hardware WoW in ath9k. Magic-packet, beacon loss triggers, deauth/disassoc patterns (a special case of user pattern) are tested with AR9485, AR9280. User pattern needs a bit of investigation on parsing to appropriate 802.11 format. we will do more rigorous testing and address bugs. Thanks a lot to Vadivel for providing me the hardware and inputs to test. Thanks to Rajkumar, Russell, Russell for their invaluable help. Thanks to Aeolous, Senthil and Sujith, Raja. Thanks a lot to Luis for providing the complete frame work for WoW in his initial wow patches.

[ath9k-devel] [PATCH 06/10] ath9k_hw: INI changes for WoW for AR9002 chipsets
From: Mohammed Shafi Shajakhan moham...@qca.qualcomm.com
for AR9002 family of chipsets and for WoW sleep, we reprogram
the SerDes so that the PLL and CHK REQ are both enabled. this
uses more power but in certain cases this is required as otherwise
WoW sleep is unstable and chip may disappear.

[ath9k-devel] [PATCH 09/10] ath9k: Add WoW related mac80211 callbacks
From: Mohammed Shafi Shajakhan moham...@qca.qualcomm.com
add suspend/resume/set_wakeup callbacks to the driver
*suspend
- bail out only if all the conditions for configuring WoW
is fine, currently multivif case is not handled
- check for associated state
- map wow triggers from user space data
- add deauth/disassoc pattern and user defined pattern.,
for the later a list is maintained
- store the interrupt mask before suspend, enabled beacon
miss interrupt for WoW
- configure WoW in the hardware by calling the
ath9k_hw_wow_enable
*resume
- restore the interrupts based on the interrupt mask
stored before suspend
- call ath9k_hw_wow_wakeup to configure/restore the hardware
after wow wakeup by clearning away WoW events and also
to know the WoW wakeup reason from the status register
*set_wakeup
- to call 'device_set_wakeup_enable' from cfg80211/mac80211
when wow is configured and as per Rafael/johannnes the
right way to do so rather in the driver suspend/resume
call back
also a minor cleanup

Why do you need AH_WOW_MAX_EVENT? It looks like out of sync and also it is
never be used.
i will correct this out in v2. also found few more unused stuff, will
correct it out. thanks for your review.

Why can't you align with existing HW_CAP_* flags? why do you need a separate
place holder?
i just thought as there are three flags specific, it would be nice to
have it as a seperate enumeration. Just found a bug that if
CONFIG_PM_SLEEP it would be a problem. will address this in v2.
