Setting up ath6kl#
Kernel configuration#
Starting from Linux kernel 3.2 ath6kl is available from kernelmenuconfig:
-> 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.
Suspend#
ath6kl supports various suspend which can be controlled with two moduleparameters, suspend_mode and wow_mode.
suspend_mode makes it possible to force a certain mode when host suspends:
value | mode |
|---|---|
0 | automatic (default) |
1 | cutpower |
2 | deepsleep |
3 | wow |
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:
value | mode |
|---|---|
0 | default |
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 isnot connected to an AP the power is cut from the wifichip. If connected to an AP WoW mode is used:
; deepsleep :
If ath6kl isnot connected to an AP the firmware is put to low powerdeep sleep state. If connected to an AP WoW mode is used.
