You can obtain the microcode from: 33 34 <http://wireless.kernel.org/en/users/Drivers/iwlwifi>. 35 36 The firmware is typically installed in /lib/firmware. You can 37 look in the hotplug script /etc/hotplug/firmware.agent to 38 determine which directory FIRMWARE_DIR is set to when the script 39 runs. 40 41 If you want to compile the driver as a module ( = code which can be 42 inserted in and removed from the running kernel whenever you want), 43 say M here and read <file:Documentation/kbuild/modules.rst>. The 44 module will be called iwlwifi. 45 46if IWLWIFI 47 48config IWLWIFI_LEDS 49 bool 50 depends on LEDS_CLASS=y || LEDS_CLASS=IWLWIFI 51 depends on IWLMVM || IWLDVM 52 select LEDS_TRIGGERS 53 select MAC80211_LEDS 54 default y 55 56config IWLDVM 57 tristate "Intel Wireless WiFi DVM Firmware support" 58 depends on MAC80211 59 help 60 This is the driver that supports the DVM firmware.

See the ftrace documentation 139 for more information. 140 141 When tracing is not enabled, this option still has some 142 (though rather small) overhead. 143 144 If unsure, say Y so we can help you better when problems 145 occur. 146endmenu 147 148endif 149
