ath10k configuration

Building

To build ath10k enable these kernel build configuration options, for example with make menuconfig:

• CONFIG_ATH10K
• CONFIG_ATH10K_PCI
• CONFIG_ATH10K_DEBUG (optional)
• CONFIG_ATH10K_DEBUGFS (optional)
• CONFIG_ATH10K_TRACING (optional)

The debug and tracing options are optional, but it's strongly recommended to enable to make it easier to debug issues.

ath10k options can be found from location:

-> Device Drivers
 -> Network device support (NETDEVICES [=y])
   -> Wireless LAN (WLAN [=y])
     -> Atheros Wireless Cards (ATH_CARDS [=m])

Loading the modules

The ath10k modules should be loaded automatically in most systems. If that's not happening, first load ath10k_core.ko and then ath10k_pci.ko.

hostapd

When building hostapd enable these configuration options:

• CONFIG_IEEE80211AC
• CONFIG_ACS

Example hostapd config to use 11ac VHT80 mode with ath10k:

interface=wlan0
driver=nl80211

ssid=ath10k-test

hw_mode=a
channel=36
ht_capab=[HT40+]
ieee80211n=1
ieee80211ac=1
vht_oper_chwidth=1
vht_oper_centr_freq_seg0_idx=42

vht_oper_centr_freq_seg0_idx is calculated for VHT80 with channel + 6.

To enable ACS:

channel=0

If you get "set channel failed to set in kernel" error message, most likely your regulatory database doesn't support 80 MHz channels.
