Go back –> ath6kl
Starting from Linux kernel 3.2 ath6kl is available from kernel menuconfig:
-> Device Drivers -> Network device support (NETDEVICES [=y]) -> Wireless LAN (WLAN [=y]) -> Atheros Wireless Cards (ATH_COMMON [=y]) -> Atheros mobile chipsets support (ATH6KL [=m])
Or alternatively search for CONFIG_ATH6KL.
ath6kl supports various suspend which can be controlled with two module parameters, suspend_mode and wow_mode.
suspend_mode makes it possible to force a certain mode when host suspends:
Definion of different suspend modes:
; automatic : the suspend mode is chosen based on host hardware capabilities ; cutpower : the chip is powered off for maximum power savings and hence resume is slower ; deepsleep : the firmware is running on the chip but is kept ; wow : if ath6kl is connected to an AP device will maintain the connection with Wake-on-WLAN feature while host is suspended
If wow mode is enabled it's possible to choose different wow submode with wow_mode parameter:
|1||cutpower when disconnected|
|2||deepsleep when disconnected|
Definion of different wow modes:
; default : Chooses the default mode from below which is subject to change. ; cutpower :
If ath6kl is not connected to an AP the power is cut from the wifi chip. If connected to an AP WoW mode is used.
; deepsleep :
If ath6kl is not connected to an AP the firmware is put to low power deep sleep state. If connected to an AP WoW mode is used.
